epression has a long history among mental health disorders, with a documented legacy dating back thousands of years to the time of ancient Greece (Hippocrates, 1923–1931, p. 185). In modern times, the disorder now ranks among the most common and greatest overall contributors to disability in industrialized countries (GBD 2015 Disease and Injury Incidence and Prevalence Collaborators, 2016). In the United States, recent estimates suggest a 12-month prevalence of about 7% and a lifetime prevalence of about 16% (Kessler et al., 2003). The classic form of clinical depression, major depressive disorder (MDD), is defined by a distinct episode lasting two weeks or longer that includes either sad mood or anhedonia and a total of five symptoms from a list of nine, which also includes sleep disruption, change in weight or appetite, fatigue or loss of energy, psychomotor retardation or agitation, difficulty concentrating or indecisiveness, feelings of worthlessness or inappropriate guilt, and recurrent thoughts of death or suicide (American Psychiatric Association, 2013). These symptoms must cause clinically significant distress or impairment of functioning in social, occupational, or other important roles. These criteria allow for a remarkable degree of variability across people who are defined as experiencing depression. Those with depression vary in their experience of specific symptoms as well as the duration and intensity of those symptoms. Depression is a highly heterogeneous disorder with regard to both symptom presentation and etiology (Lorenzo-Luaces, 2015). Onset of MDD can occur at any age; however, during puberty, risk of onset increases substantially, with https://doi.org/10.1037/0000219-001 Handbook of Cognitive Behavioral Therapy: Vol. 2.

girls experiencing significantly higher rates than boys (Kessler et al., 2003). In some cases, MDD presents as a chronic disorder, whereas for others, episodes of depression remit and recur over time. Chronicity of depressive symptoms is associated with increased risk of comorbid personality, anxiety, and substance disorders, as well as reduced likelihood of full symptom remission following treatment (Klein & Black, 2017). Risk of recurrence is higher among those with more severe symptoms, multiple prior episodes of MDD, or residual symptoms during remission (Strunk & Sasso, 2017). Although some have suggested that MDD be considered primarily a highly recurrent or even chronic disorder, evidence also indicates that a substantial portion of cases are characterized by a single time-limited episode with no subsequent recurrences (Monroe & Harkness, 2011). In accordance with the heterogeneity observed in the symptoms and course of depression, there is also considerable variety seen in approaches to its treatment. Among these, the cognitive aspects of depression have attracted a great deal of interest, with research efforts in this area developing into a major theoretical perspective in the 1960s. Beck suggested that depression is characterized by overly negative views of one’s self, world, and future. Subsequent research has shown that people with depression tend to experience more negative thoughts than those without depression (Beck & Bredemeier, 2016), and focusing on negative thoughts appears to prolong depressive episodes (Nolen-Hoeksema, 1991). Researchers have debated whether the less positive views of those with depression tend to be inaccurately negative (as Beck had suggested) or might instead be realistic (i.e., the depressive realism hypothesis; see Alloy & Abramson, 1988). Although findings have been mixed (Moore and Fresco, 2012), there is evidence that patients with a clinically significant level of depression tend to exhibit key negative biases and that these biases may be particularly pronounced for emotionally engaging self-relevant judgments (Strunk & Adler, 2009; Strunk et al., 2006). Depression is also associated with increased elaboration of negative information and impaired ability to inhibit or disengage from negative cognition, even when it is irrelevant to the current task (Joormann & Gotlib, 2010). Those with depression also tend to engage more often in generally maladaptive emotion regulation strategies, such as avoidance, rumination, and suppression, and they use generally adaptive strategies, such as problem solving or reappraisal, less often than those who are not depressed (Aldao et al., 2010). Findings such as these support a view of depression in which cognition and emotion play central roles. In this chapter, we review several of the most prominent models of cognitive behavioral treatments for depression, addressing their theoretical rationale, evidence of treatment efficacy, possible mechanisms, and recent efforts to disseminate these treatments. We also address some of the special issues facing cognitive behavioral therapists working with patients with depression and discuss the impact of some of the most common comorbid conditions.1 Clinical examples are disguised to protect patient confidentiality.

MODELS OF COGNITIVE BEHAVIORAL TREATMENTS FOR DEPRESSION The models underlying cognitive behavioral approaches share a view that thoughts, behaviors, and emotions are fundamentally and dynamically interrelated, and that these relations can be leveraged to bring about meaningful improvement in dysfunctional or distressing psychological states. Some cognitive behavioral treatments aim to correct overly negative views thought to be associated with depression. Others are directed at promoting acceptance of these experiences rather than changing them per se. Still others aim to identify and leverage individual functional associations thought to maintain each individual’s depression. Although formalized cognitive behavioral therapies are less than half a century old, these foundational concepts have deep historical and philosophical roots. The Stoics of ancient Greece and thinkers from the Taoist and Buddhist traditions highly emphasized the relations between emotions and thought. For example, Epictetus (ca. 125/1955) wrote, “Men are disturbed not by things but by the views which they take of them” (p. 19). Leveraging the relations between thoughts, emotions, and behavior to treat psychopathology became a primary focus in clinical psychology during the 20th century. Freud developed a highly influential approach to the treatment of psychological distress by targeting unconscious cognitions through psychoanalysis. Although the primacy granted to unconscious drives is not part of most cognitive behavioral conceptualizations, the more fundamental insight that clinical improvement may be possible through individual verbal psychotherapy sparked significant development in psychotherapy theory and practice for the decades that followed. Many post-Freudian approaches have emphasized the role of effortful changes to maladaptive cognitive and behavioral processes in order to treat psychopathology. Although some behaviorists initially eschewed cognition as inessential and overly subjective, later theorists successfully integrated cognitive and behavioral approaches to understanding and treating mental health disorders. Among the various maladaptive processes examined in this integrated cognitive behavioral tradition, there has been a special interest in the role of inaccurate cognitions in causing psychological difficulties. For example, Lazarus, a student of the behaviorist Wolpe, suggested that behavioral change may either precede or follow the “correction of misconceptions” that is the primary aim of psychotherapy (Lazarus, 1972). Ellis’s rational-emotive psychotherapy explicitly connects “activating events” to “emotional consequences” via “intervening beliefs,” which may lead to dysfunction when based upon faulty assumptions (Ellis, 1957, 1962). Thus, cognition and cognitive change have occupied a central place in the cognitive behavioral models for decades. The most widely studied and disseminated of the cognitive behavioral psychotherapies is Beck’s cognitive therapy (CT; Beck et al., 1979), which was heavily influenced by these developments. We now discuss its application to the treatment of depression.
6 Strunk, Pfeifer, and Ezawa
Cognitive Therapy Aaron T. Beck (1967) put forth a cognitive model of depression that emphasized unrealistically negative views as playing a central role in the etiology and maintenance of depression. On the basis of this model, Beck et al. (1979) developed an active, structured psychotherapy aimed at correcting these negative thoughts and beliefs—a treatment they called cognitive therapy (CT). In CT, therapists and patients work together to identify the patients’ negative thoughts and beliefs and use a variety of cognitive and behavioral strategies in an effort to foster more realistic views. The primary focus in CT is on patients’ current problems, although attention can be directed to either the patient’s past or the therapeutic relationship as needed. Sessions are structured with therapists and patients working together to set and follow an agenda at each session. Rather than adhering to a highly prescribed session-by-session guideline, the CT manual calls for a flexible, principle-based approach in which each patient’s treatment is informed by their specific goals and individual case conceptualization. CT includes behavioral strategies, with these strategies being used primarily as a means of bringing about cognitive change. Among the most important of the behavioral strategies used in CT are self-monitoring and behavioral experiments. Self-monitoring involves patients recording their activities and moods, typically each hour across a number of days. Using self-monitoring data, the therapist and patient can work together to identify information that could be used to evaluate any of the patient’s negative predictions. Therapists can also use such data to help patients break down challenging activities into smaller, more easily accomplished parts. A particularly compelling approach occurs when a patient’s negative thoughts or beliefs can be effectively tested through a behavioral experiment. Behavioral techniques also often play an important role in addressing sleep difficulties. Finally, role-play and behavioral rehearsal can be important strategies in working with patients to develop assertive strategies for addressing interpersonal challenges. The primary focus of CT is working to identify, evaluate, and respond to negative thoughts and beliefs. Patients are taught to pay special attention to their automatic thoughts. Therapists introduce thought records as a vehicle to record the patient’s thoughts and feelings related to specific situations. Thought records also serve as key aids in the process of reevaluating one’s automatic thoughts, guiding patients through a series of questions that can help them arrive at more complete, accurate reevaluations of their initial thoughts. As treatment progresses, therapists work with their patients to identify and evaluate patients’ schemas or core beliefs. Patients’ specific thoughts are understood as being influenced by their schemas (i.e., basic cognitive structures that organize information; Beck et al., 1979). Recognition of one’s core beliefs is thought to promote recognition and successful responding to one’s automatic thoughts as well as ultimately fostering change in these beliefs.
Depression 7
Behavioral Activation and Problem-Solving Therapy Behavioral activation (BA) is a therapy that emphasizes the use of focused activation strategies to help depressed patients approach and access sources of positive reinforcement in order to reduce depressive symptoms (Martell et al., 2001). BA is based in the contextualist tradition (see Ferster, 1973), defining depression as the result of unconditioned responses to an environment either devoid of positive reinforcement or saturated with punishment. Emphasis is placed on the role of avoidance behaviors in particular, which further reduce the availability of positive reinforcers and intensify depression. BA promotes increased activation as the remedy for this cycle of avoidance and depression. A key distinction between BA and CT, which includes many of the same behavioral techniques, is the therapist’s aim in implementing behavioral change. In CT, a primary target of behavioral change is cognitive change (Beck et al., 1979; Hollon, 1999), whereas the rationale for BA suggests that behavioral change alone is sufficient to treat depression. Problem-solving therapy is a cognitive behavioral intervention based on the relational/problem-solving model of stress (Nezu et al., 2013), which identifies effective problem solving as an important moderator of the effects of life stress on negative physical and mental health outcomes. The treatment is primarily focused on improving (a) the patient’s problem orientation, defined as a set of generalized beliefs, attitudes, and emotional reactions to problems in living and one’s ability to cope with them, and (b) problem-solving style, which refers to the patient’s cognitive and behavioral tools for coping with stressors. The program begins with didactic presentation of the developers’ model of problemsolving training, which includes discussion of effective problem orientation, problem formulation, generation of alternative solutions, decision making, and solution implementation and verification. Patients are assisted in implementing these tools in domains relevant to their lives, including the use of homework assignments to help generalize skills. Cognitive Behavioral Analysis System of Psychotherapy The cognitive behavioral analysis system of psychotherapy (CBASP; McCullough, 2000) is another package used in the treatment of individuals with depression. James McCullough developed CBASP in an attempt to emphasize the role of interactional issues that were less emphasized in preceding cognitive behavioral theories and treatment approaches to depression (i.e., those that primarily focused on intrapersonal cognitive and behavioral aspects). The model underlying CBASP is that depression is characterized by Piagetian preoperational thinking (i.e., a stage of cognitive development marked by lacking concrete and abstract logical reasoning), which maintains depression. Treatment is focused on helping patients recognize they are disconnected from their environment and environmental consequences/feedback, and their sense of helplessness/ hopelessness is an indication that they have not yet recognized their connection
8 Strunk, Pfeifer, and Ezawa
to the world. The model underlying CBASP represents a blend of cognitive, behavioral, interpersonal, and psychodynamic perspectives. Acceptance and Commitment Therapy Acceptance and commitment therapy (ACT; Hayes et al., 2012) encourages patients to accept their experiences, including their experiences of depression, without trying to change them directly. Using a process called cognitive defusion, patients are encouraged to see that their thoughts convey no inherent meaning. The emphasis on recognizing that one’s thoughts do not convey inherent truth was referred to as distancing in Beck’s CT. In fact, early writings about ACT called it comprehensive distancing. Treatments Focused on Preventing Relapse and Recurrence As we describe in more detail later, one of the key empirical findings regarding CT is that it appears to offer patients not only acute symptom relief, but also effects that endure long after treatment has ended. Rather than working to develop an acute treatment that also offers enduring effects, some treatment developers have used alternative approaches. One alternative is to continue the use of cognitive behavioral treatment after acute treatment has proven successful (i.e., continuation treatment; Jarrett et al., 2013). A second alternative is to develop treatments not intended to serve as acute treatments, but which nonetheless may offer protection from relapse and recurrence when provided after someone has recovered from a depressive episode. Taken together, available evidence suggests that these various kinds of cognitive behavioral approaches appear to provide some protection from risk of relapse following remission (Hollon et al., 2006; Vittengl et al., 2007). In this section, we review three treatments developed for preventing relapse and recurrence: mindfulness-based CT (MBCT), well-being therapy (WBT), and preventive CT (PCT). MBCT typically involves 8 to 10 weekly 2-hour sessions, with daily meditation practiced outside of session. The first few sessions are focused on becoming aware of how the mind wanders and how to refocus it. The next few sessions are then focused on how to handle mood shifts. The last session of MBCT involves encouraging patients to become aware of personal warning signs of impending relapse and to develop specific plans on how to handle this occurrence. This treatment combines techniques from both traditional CT for depression and mindfulness meditation (Segal et al., 2002). The mindfulness aspect of this therapy involves working toward a nonjudgmental awareness of the present moment and environment. Patients are taught to practice meditation and breathing techniques, as well as to become more aware of their thoughts, emotions, and bodily sensations. By practicing these techniques, patients develop the ability to decenter and relate to their emotions and thoughts in a more accepting way. These techniques are practiced with the aim of preventing negative rumination and subsequent depressive relapse. Thus, patients learn to
Depression 9
both adopt more realistic and skillful responses to unwanted thoughts and accept unwanted thoughts in a manner that is thought to protect against rumination and mood worsening. WBT is another prevention effort that involves cognitive and behavioral techniques, but complemented with elements of psychological well-being (Fava, 1999a, 1999b). It is usually conducted over eight weekly sessions with structured homework assignments completed between sessions. The first sessions of WBT involve teaching and encouraging patients to keep a diary to track thoughts, emotion, and behaviors that affect the patient’s sense of well-being. These connections are then discussed and evaluated in session. Patients are also encouraged to increase activities that lend to a positive sense of well-being. Later sessions of this treatment then focus on identifying and discussing thinking errors and finding alternative thoughts. PCT is also a modified form of traditional CBT that was developed for relapse and recurrence prevention of depression (Bockting et al., 2005). PCT typically involves eight weekly, 2-hour sessions conducted in a group-therapy format. The groups usually consist of seven to 12 patients and the therapist. Though PCT is a CBT-based program, PCT is comparatively less focused than traditional CBT on modification of current negative, dysfunctional thoughts. Instead, PCT treatment begins with focus on the identification of core dysfunctional attitudes, assumptions, and beliefs that are often latent, but easily activated, in remission. Once identified, PCT uses CT techniques (e.g., Socratic questioning) to challenge the attitudes, assumptions, and beliefs. In a similar manner as traditional CBT, patients are encouraged to practice techniques outside of the sessions. Moreover, patients are encouraged to keep a diary of positive experiences to help the storage and retrieval of specific positive memories. In addition, the last session in PCT involves developing individual prevention plans. These plans include identification of warning signals for relapse, such as psychological vulnerability factors and expected stressful events, and helpful strategies to use when these warning signals occur.
SPECIAL CONSIDERATIONS WITH PATIENTS WITH DEPRESSION Cognitive behavioral therapists should be mindful of some special concerns related to the treatment of depression. Most significantly, depression can be a fatal disorder. The prevalence of suicide among those with MDD is estimated to be between 2% and 6% (Michaels et al., 2017). Significant risk factors for a suicide attempt include having a specific plan for attempting suicide, being within a year of the initial onset of suicidal ideation, previous suicide attempts, hopelessness, and comorbid psychiatric disorders (Beck et al., 1985; Kessler et al., 1999; Suominen et al., 2004). Joiner’s interpersonal theory of suicide emphasizes three factors that increase risk for suicide: perceived burdensomeness, thwarted belongingness, and acquired ability/access to means of suicide (Joiner, 2005). Therapists must be aware of suicide risk factors, carefully assess
10 Strunk, Pfeifer, and Ezawa
suicidality throughout treatment, and actively work with patients to prepare a crisis plan. It is critical that therapists gain an accurate understanding of the nature, duration, and intensity of their patients’ thoughts, plans, and prior experiences regarding suicide. Inaccurate assessment may obscure the true risk of an impending suicide attempt, with potentially devastating consequences— whether it results in a patient’s death or the termination of therapy following disproportionate action taken by the therapist. Providers of CBT also must contend with the fact that lack of motivation and low energy are common symptoms of depression and may undermine patients’ efforts to make the changes that are a key focus in CBT. Therapists commonly hear patient reports that depression interfered with completing homework, contributed to their arriving late, or caused them to miss sessions altogether. Such experiences can be viewed as “grist for the mill,” or experiences that can be used to highlight the application of CBT procedures for overcoming such obstacles. Strategies such as structuring activities and working to counteract negative views as one undertakes such efforts are especially important. In the vignette below, we illustrate one way a therapist might help a patient to overcome difficulty in completing an early homework assignment. THERAPIST:
Let’s take some time to talk about the homework from last week. How did it go tracking your mood with the activity log?
PATIENT:
Well, I started filling it out, but then it slipped my mind and the week got away from me. I think I left it at home.
THERAPIST: Sounds like you had some trouble with it. Why don’t we start by
going back to the last moment you thought about working on it? Do you remember when that was? PATIENT:
I think it was the day after our last session. I realized that I hadn’t filled it out at all that day—I think I realized it sometime that night, just before bed.
THERAPIST: Okay. That sounds important. Do you remember how you felt at
that time? PATIENT:
I felt really down about it. I was disappointed in myself. Here I am finally in therapy working on what seemed like a pretty straightforward assignment and I can’t even do that.
THERAPIST: I know you were disappointed, but I’d like to point out that
you’re doing a great job identifying your thoughts and feelings now. It sounds like you took not filling out the form as an indication of your inability to do well in therapy. PATIENT:
Well, yeah. If I can’t do this, I didn’t really see how I was going to succeed in this treatment. We’re just getting started, and I’m already falling short.

THERAPIST: Okay, so you took this as a strong indicator about how you’ll do
in treatment. Do you imagine others have struggled with this assignment? PATIENT:
I wasn’t thinking about it, but I suppose some have.
THERAPIST: Absolutely. It’s very common. And nonetheless, people who
struggle with the assignment initially often go on to have very positive results with treatment. Remembering to do the assignment regularly is almost always a challenge for folks. Fortunately, it doesn’t have to be perfect to be useful to us. So, if you miss some time, you can just do your best to fill in what you missed. PATIENT:
Okay, I know we talked about checking in with the form at least twice a day, at lunch and around bedtime.
THERAPIST: How did that work as a plan? PATIENT:
It was okay, but I was busy at lunch and missed the check-in. Then, it seemed like I had really gotten off track with my plan when I looked it over in the evening and there wasn’t much filled out.
THERAPIST: Okay, and once you were off track then you didn’t continue
with the assignment? PATIENT:
Yeah, I thought I had already messed it up, so there really wouldn’t be much point in doing it partially.
THERAPIST: It is true that filling it out more completely is helpful, but we’re
often able to learn a lot from it—even if it’s only partially completed. Actually, sometimes the missing parts are quite informative. Our discussion here has led us to highlight some ways you were thinking about the assignment that served to make it harder to keep up with it. PATIENT:
I guess that’s true.
THERAPIST: I wonder, if we try this again and you miss some time filling it
out, are there some things that would be important to remind yourself of, so that you’re able to keep working on it? PATIENT:
Well, I could remind myself that it’s not uncommon to miss some time when tracking.
THERAPIST: Terrific. I think that’s a great thing to remember. Let’s jot that
down. Could you write that as a reminder on this new activity log I have for you? . . . Any other reminders you would want to note?
12 Strunk, Pfeifer, and Ezawa
PATIENT:
I could also remind myself that we can still learn from the assignment if I do it partially.
THERAPIST: Super! I think that will be really key. Let’s jot that down too. PATIENT:
Okay, got it.
THERAPIST: I think it could be really helpful to have those reminders at the
ready when you’re working on the form. What do you think? PATIENT:
It could help.
THERAPIST: Nice. Now, why don’t we go back and try to recreate a record of
some of the moods and activities you’ve experienced over the past few days and see what we can learn from that. This vignette was intended to illustrate how a therapist can use a cognitive approach to helping patients identify and overcome obstacles to successfully working on therapeutic assignments. Another concern that can arise in CBT for depression is that patients may either misunderstand or have concerns about the treatment rationale. Two of these merit special attention. First, some patients may misunderstand CBT and believe they are being asked simply to “think positively.” CBT’s focus on weighing evidence for and against negative automatic thoughts and considering more realistic alternatives does not amount to endorsing positive thinking in the absence of supporting evidence. If one simply rehearses positive thoughts to replace negative ones without regard for the evidence, the new thoughts may not be believable and therefore may not promote lasting improvements. In fact, there is some evidence to suggest that among those who respond to CBT, those who show extreme positive thinking have a greater risk of relapse (Forand & DeRubeis, 2014; Teasdale et al., 2001). It may be that those patients whose takeaway from CBT is to replace negative thoughts with positive ones, without a careful review of the evidence for those views, are at greater risk of relapse. THERAPIST: [after discussing the CBT rationale] What’s your reaction to
hearing about the approach we take in CBT? Do you have any thoughts about why it might or might not be helpful for you? PATIENT:
I don’t think so. I guess I can try it.
THERAPIST: You sound hesitant. Are there any parts of the treatment that
you are concerned about? PATIENT:
To be honest, I’ve tried to replace negative thoughts with positive thoughts. It just hasn’t worked for me. So I am not sure what’s going to make it work now.
Depression 13
THERAPIST: Okay, I really appreciate your sharing your concern with me. I
agree with you that just replacing our negative thoughts with positive ones may not be a great strategy. If you try to change your view just by thinking more positively, it can be difficult to sustain, because there’s not much making those more positive views believable. That’s why our approach is a bit different than that. In CBT, we will really emphasize examining evidence to carefully evaluate any automatic thoughts we consider. It’s only following this careful examination of evidence that we would try to formulate new thoughts—thoughts that align closely to what a careful review of the evidence supports. PATIENT:
I feel like my negative thoughts are often more accurate than any optimistic thoughts I might try to come up with.
THERAPIST: Some of your negative thoughts may be true, or may have
important elements of truth to them. To the extent your negative thoughts are true, we’ll talk about the best ways to cope with your situation. But we generally find that for people with depression, even if there’s some truth to their automatic thoughts, there are very often some overly negative aspects as well. So I would just ask that you keep an open mind to see what the process of evaluating your thoughts more carefully might reveal. Often times, people with depression are surprised to see there are different, more realistic ways to look at things. And these changes in their thoughts can often lead to improvements in your mood. Would you be willing to try it out? THERAPIST: Yeah, I guess so. I like the idea that I will be strengthening my
thinking by making it more rooted in facts, instead of just changing it to something more positive. A second potential misunderstanding emerges if patients interpret their therapist’s efforts to evaluate evidence for their beliefs as failing to recognize and appreciate their truly difficult life circumstances. Some patients may respond with frustration if they believe their therapist does not accurately understand the extent of their pain and hopelessness. This is an unfortunate scenario because many cognitive behavioral techniques can be used to alleviate suffering and bolster problem-solving skills even in terribly difficult circumstances. Cognitive behavioral therapists must repeatedly articulate the cognitive behavioral model to clear up such misunderstandings when they arise. Therapists should both be able to distinguish validation of patients’ emotions from validation of the accuracy of patients’ thoughts and beliefs and also be cognizant of the ways CBT techniques can be beneficial even when circumstances are bleak (e.g., major losses such as homelessness or terminal illness).

EFFICACY OF COGNITIVE BEHAVIORAL TREATMENTS FOR DEPRESSION We now turn to evidence regarding the efficacy of cognitive behavioral treatments. We cover these selectively, focusing on a few treatments that have been particularly well studied. The most extensively studied of these treatments is CT. The strongest evidence for the efficacy of CT comes from trials comparing it with antidepressant medication. Taken together, evidence from these trials suggests that the acute (e.g., 12- to 16-week) effects of CT are comparable to antidepressant medication. However, this comparison has not been without controversy. Findings from the Treatment of Depression Collaborative Research Program (TDCRP) raised the possibility that for more severe forms of depression, antidepressant medication may be more efficacious than CT. In a reanalysis of data from that trial (Elkin et al., 1995), an initial depressive symptom severity by treatment interaction suggested that medication was more efficacious than CT, but only among the more severely depressed patients. Nonetheless, this pattern was not evident in an analysis that pooled data from four trials including the TDCRP (DeRubeis et al., 1999). In a subsequent larger trial focused on moderate to severe depression in outpatients, the investigators failed to find an overall difference between CT and medication, with both treatments showing the same response rate of 58% after acute treatment (DeRubeis et al., 2005). Thus, the best available evidence suggests that CT and medication do not differ in their acute impact on depressive symptoms. This is true both overall and specifically among more severely depressed patients. Whereas initial depressive symptoms do not appear to serve as a moderator of the impact of CT versus medications on depressive symptoms, initial depressive symptoms do appear to be a vital moderator of specific effects of a treatment relative to a control treatment. In an analysis of data from six trials, Fournier et al. (2010) found that the advantage of medication over pill placebo was moderated by initial symptom severity. Medication outperformed placebo at moderate to high levels of depressive symptoms, with the greatest benefit observed among patients in the very severe group (Cohen’s d = 0.47), but this difference was small and nonsignificant for those with mild-to-moderate depressive symptoms. A similar moderating effect has been reported for the comparison of psychotherapy and control conditions; the difference varied as a function of initial severity with the difference only being clear among the more severely depressed patients (Driessen et al., 2010). Thus, the specific benefit of current treatments for depression does appear limited to moderate-to-severe depression. For mild-to-moderate depression, there is little evidence that any treatment offers specific benefits (above those offered by a control condition). Having considered evidence relevant to evaluating the acute outcomes of CT, we now consider long-term outcomes. CT includes a strong emphasis on fostering a set of coping skills that patients can use after the conclusion of treatment to help prevent relapse and recurrence. Across trials examining cognitive
Depression 15
behavioral treatments for mood and anxiety disorders, much of the available evidence indicates that CT has strong enduring effects (Hollon et al., 2006). Following the sample of moderately to severely depressed patients who participated in the DeRubeis et al. (2005) trial, Hollon et al. (2005) examined the patients who responded to CT or medication. Those who responded to medication were randomized either to continue their medication or to switch to a pill placebo. Relapse rates over the 1-year follow-up period were 76% for discontinued medication, 47% for continued medication, and 31% for prior CT. Patients with prior CT were at significantly lower risk of relapse in the year following treatment than patients who discontinued medication. Cuijpers et al. (2013) found a similar pattern of results when aggregating follow-up data from 506 patients across several trials. In this meta-analysis, for every five patients treated with CT rather than discontinued medications, a relapse was prevented. When considering both acute and long-term outcomes, the advantages and disadvantages of CT and medication become clear; the choice appears to be between what could be a time-limited course of CT (that confers enduring effects) or medication continued for an extended period. In fact, patients are often encouraged to stay on medications indefinitely. The comparison of long-term outcomes for medication and CT raises important questions. Are the observed long-term differences in these treatments attributable to the effects of having participated in CT? Or are they attributable to the negative consequences of discontinuing medication? What accounts for prior exposure to CT outperforming discontinued medication? If one assumes that any effects of medication are short-term, then one would be likely to look to what patients learned in CT to explain this difference. However, common clinical trial designs have not ruled out the possibility that medication, well after it has been discontinued, might increase people’s vulnerability to depression (Andrews et al., 2011; Whitaker, 2010). This is because trials have focused overwhelmingly on testing drug–placebo differences to evaluate acute effects and continued–discontinued medication differences following treatment to evaluate long-term effects. Drawing on comparisons of CT and other psychotherapies, there is some evidence that what patients learn in CT specifically may serve to protect them from relapse. In their examination of long-term outcomes in a clinical trial of CT and ACT for mixed anxiety and depression, Forman et al. (2012) found that patients who had received CT reported significantly less depressive symptomatology and better functional outcomes than those who had participated in ACT. Specifically, at the 18-month follow-up, about one-third more CT patients than ACT patients were in the normative range of depressive symptoms, and more than twice as many CT patients than ACT patients were in the normative range of social/occupational functioning. Nonetheless, there is still a substantial need for well-powered, head-to-head randomized comparisons evaluating the long-term effects of CT versus other forms of psychotherapy. In addition to CT, several other forms of CBTs also have established efficacy as treatment for depression. BA, CBASP, and problem-solving therapy are
16 Strunk, Pfeifer, and Ezawa
among those recognized by the American Psychological Association, Division 12, as having strong research (American Psychological Association, 2018). BA has garnered considerable attention in recent years, perhaps due to the claim that it can be implemented successfully with clinicians with minimal qualifications in the absence of extensive training. An early trial supporting the efficacy of BA was a component analysis study of CBT for depression (Jacobson et al., 1996). In this study, the investigators found no differences in treatment outcome between CBT and BA. In a subsequent trial comparing BA, CT, medication, and placebo, the researchers compared the treatments separately for more and less severely depressed patients. Among the more severely depressed portion of the sample, BA did not differ from medication and significantly outperformed CT (with no differences in the less severe part of the sample; Dimidjian et al., 2006). Longitudinal follow-up of relapse and recurrence suggested that both BA and CT did well, outperforming discontinued medication (Dobson et al., 2008). These results are quite promising for the efficacy of BA. What about the clinical benefits of treatments intended to reduce risk of relapse or recurrence among patients who recently responded to another treatment? MBCT is among the more commonly studied of these treatments. Evidence suggests that MBCT does provide protection against relapse or recurrence, but this is limited to patients who have a history of a number of depressive episodes (Teasdale et al., 2000). A meta-analysis of six trials examining the prevention of relapse following MBCT for depression reported that MBCT patients’ risk of relapse was reduced by 34% compared with those receiving treatment as usual or placebo, and that those patients with three or more prior episodes of depression experienced a relative risk reduction of 43% (Piet & Hougaard, 2011). In addition, a recent component analysis of MBCT failed to find that the specific treatment strategies incorporated into the treatment yielded any better outcomes than a rigorous control condition that lacked those treatment components (Britton et al., 2018).
DISSEMINATION AND IMPLEMENTATION After establishing the efficacy of a treatment, testing its effectiveness is important to evaluating the generalizability of the treatment’s benefits in the “real-world” conditions in which it may be used. Some key limitations common to many dissemination practices for evidence-based therapies have been identified, including poor assessment of treatment fidelity, little follow-up to assess the long-term effects of the intervention, and inadequate development of evidence-based training procedures (Karlin et al., 2012; Rakovshik & McManus, 2010; Shafran et al., 2009). Considerable systemic obstacles to dissemination are also apparent, including insufficient supply of trained mental health professionals, inadequate support for mental health service delivery, enduring stigma toward mental illness and treatment, as well as a potential for cultural incompatibilities with evidence-based practice (Damschroder et al., 2009;
Depression 17
Kanter & Puspitasari, 2016; Karlin et al., 2010; Lewis et al., 2016). Researchers have called for more comprehensive efforts to evaluate dissemination programs (McHugh & Barlow, 2010), and there are several notable efforts for depression underway. We note a few of the larger efforts, which focused on CT-inspired CBT and BA. The single largest dissemination and implementation program in the United States for CBT for depression is the Department of Veterans Affairs (VA) CBT-D program (Karlin et al., 2010). With the goal of training VA personnel (psychologists, psychiatrists, social workers, and advanced practice nurses) to competency, CBT-D includes experiential training workshops to teach the theory and application of CBT, as well as ongoing weekly consultation with CBT experts, following a manual specifically adapted for veterans and service members. The treatment approach is an adaptation of CT for depression. Initial results from this program were that over 80% of therapists who participated in the program completed all elements of training and achieved competency; however, the way in which these efforts impact therapeutic outcomes relative to alternatives is a vital question that remains (Karlin et al., 2012). In the United Kingdom, the Improving Access to Psychological Therapies (IAPT) program is an effort to expand access to psychotherapy based on cognitive behavioral principles among adults with anxiety and depression (Keen & Freeston, 2008; McManus et al., 2010). Several thousand providers have been trained through IAPT, with plans to train thousands more in the coming years. IAPT utilizes a stepped-care model, with separate training programs for high-intensity CBT therapists and low-intensity psychological well-being practitioners (PWPs; Clark, 2018). Many people with mild-to-moderate depression or anxiety disorders first receive treatment from a PWP, which could include computerized CBT, psychoeducational groups, or guided self-help. Those who do not improve are then offered treatment with a high-intensity therapist trained in one of the evidence-based therapies recommended by the National Institute for Health and Clinical Excellence. All therapists receive weekly supervision. Pre-post outcome scores were available for over 90% of patients, and 40% of patients met clinical cutoffs for recovery at posttreatment (Gyani et al., 2013), suggesting the potential promise of such a program. Some have advocated for greater efforts toward disseminating BA as opposed to CT on the basis that BA may require less intensive training that could be completed at a lower cost (Martell et al., 2001). In a recent noninferiority trial (i.e., a trial to test whether one treatment is comparable to another), BA provided by less expert therapists appeared to yield effects over 1 year that were comparable to those achieved with CT (Richards et al., 2016).
COMORBIDITY AND OTHER COMPLICATING FACTORS A commonly raised concern regarding the effectiveness of CBT for depression is whether its effects are attenuated for complex presentations. In addition,
18 Strunk, Pfeifer, and Ezawa
some have suggested that comorbid conditions are associated with weaker treatment outcomes in CBT for depression, but also that the compromised performance of treatment can be limited by using highly competent therapists (Kuyken & Tsivrikos, 2009). Below, we review evidence for the efficacy of cognitive behavioral treatments for depression in cases with complex or comorbid presentations. Persistent/Recurrent MDD A considerable portion of those with MDD experience recurrences (Strunk & Sasso, 2017). CBT has a documented enduring effect that reduces the risk of relapse or recurrence (Hollon et al., 2005, 2006) and appears to persist for years after treatment (Paykel et al., 2005). Continuation CBT (i.e., continued sessions provided following acute treatment, often occurring less frequently) also reduces risk of relapse (Vittengl et al., 2007). For patients with three or more previous episodes, MBCT appears to be an effective treatment for relapse prevention (Kuyken et al., 2008; Piet & Hougaard, 2011; Teasdale et al., 2000). Unstable remission, prior episodes of MDD, childhood trauma, and early age of onset have been identified as markers of risk for relapse and recurrence that might be used to select patients for relapse prevention strategies or continuation treatment following remission (Bockting et al., 2015). Anxiety Disorders Although CBT is an efficacious treatment for both depression (DeRubeis et al., 2005) and anxiety disorders (Chambless & Peterman, 2004) separately, the way in which comorbid anxiety impacts the treatment of depression has been a source of some controversy. Comorbidity between depression and anxiety is common, leading some to suggest that anxiety and depressive disorders have significant diagnostic overlap (Zajecka & Ross, 1995) and shared etiology (Moses & Barlow, 2006). When anxiety is comorbid with depression, prognosis is poorer (Zajecka & Ross, 1995), there is a greater likelihood of residual symptoms and risk of relapse (Keller & Hanks, 1995), rates of improvement slow, and dropout rates increase (Brown et al., 1996). Generally, those who respond to treatment for one disorder tend to experience improvement in both depression and anxiety (Allen et al., 2010; Emmrich et al., 2012; Tsao et al., 2002, 2005). Nonetheless, a common dilemma facing therapists of patients with comorbid depression and anxiety is whether to tackle one of the two issues first, or whether to try to integrate the treatments in some way. Although not focused on depression specifically, Craske et al. (2007) randomized patients with panic disorder to either CBT for that disorder or CBT that allowed for “straying” to comorbid disorders. The focused form of CBT yielded better outcomes, raising the possibility that treatments might optimize outcomes by focusing on one core clinical problem at a time. Similarly, Gibbons and DeRubeis (2008) found that to the extent to which therapists
Depression 19
providing CT for depression strayed to address anxiety (as opposed to depression), their patients tended to achieve less improvement in both depression and anxiety symptoms. Taken together, these results suggest that various treatment procedures may be effective in cases involving comorbid depression and anxiety disorders, but that switching too frequently between them may undermine overall effectiveness. Personality Disorders There is a commonly held view that comorbid personality disorders (PDs) are a poor prognostic indicator in the treatment of MDD, though findings and conclusions regarding them have been mixed (Kool et al., 2005; Newton-Howes et al., 2006). However, a recent meta-analysis coauthored by those who had been on opposing sides of this issue showed that comorbid personality disorder diagnosis does predict poorer treatment outcome among patients with depression. In their analysis, those with a comorbid personality disorder were more than twice as likely as those without to experience a poor outcome (odds ratio = 2.16; confidence interval [1.83, 2.56]; Newton-Howes et al., 2014). In a large trial of CT for depression versus medication, medication outperformed CT when comorbid PDs were present, but CT outperformed medication among those without comorbid PDs (Fournier et al., 2008). Patients with comorbid PDs had a 44% response rate compared with 66% among medication patients; however, for those who did respond to acute CT, nearly all experienced a sustained response. These results, taken together, suggest that comorbid PDs complicate treatment of depression and make a poorer response likely. Some evidence suggests that medication may have an advantage over CBT in the treatment of depression with personality disorders; however, efforts to replicate such findings are needed. Substance Use Disorders According to the National Epidemiologic Survey on Alcohol and Related Conditions, the 12-month prevalence of comorbid substance use disorders among those with MDD is estimated to be 19% (Grant et al., 2004). In the majority of these cases, the onset of substance use disorders is temporally secondary to that of MDD (Kessler et al., 1997). A recent meta-analysis concluded that combined CBT and motivational interviewing (MI) outperformed treatment-as-usual for alcohol use disorders with comorbid depression (Riper et al., 2014). These results suggest that targeting both substance use and depression simultaneously may be an effective approach, with preliminary evidence that computer-based treatments may have similar efficacy as individual face-to-face CBT/MI (Kay-Lambkin et al., 2009). However, a major limitation in this literature is that many studies of CBT for depression exclude cases involving substance use disorders, particularly substance dependence. As a result, comparatively little is known about whether comorbid substance use disorders interfere with CBT for depression.
20 Strunk, Pfeifer, and Ezawa
Medical Conditions Numerous studies have posited a link between depression and physical health outcomes. In a World Health Organization survey, results showed that MDD is present in 9% to 23% of those with chronic physical diseases such as cardiovascular disease, arthritis, asthma, and diabetes. Depression is also commonly associated with chronic pain (Bair et al., 2003; Breivik et al., 2006), and patients with depression are three times more likely to be noncompliant with medical treatment recommendations than those without depression (DiMatteo et al., 2000). These findings suggest that depression may compound the effects of serious medical issues. CBT for depression appears to be associated with benefits in the treatment of such conditions; for example, the combination of CBT and supportive diabetes education outperformed supportive diabetes education alone in achieving remission of depression, as well as in follow-up mean glycosylated hemoglobin levels among patients with Type 2 diabetes and comorbid MDD (Lustman et al., 1998). CBT has also been associated with improvements in perceived disability and current pain in the treatment of nonspecific chronic low back pain (Smeets et al., 2006), and it is increasingly a topic of study as a treatment for a variety of chronic pain conditions (Turner et al., 2007). Another area of interest is the use of CBTs, especially mindfulness-based approaches, to reduce depression in cancer patients (Cramer et al., 2012; Shennan et al., 2011).
MECHANISMS OF CHANGE Because psychotherapies are long, complex interventions, evidence of the efficacy of such interventions leaves important questions about which aspects of the treatments are responsible for therapeutic gains unanswered. Psychotherapy process research seeks to address these questions by assessing the degree to which variability in therapeutic procedures is related to therapeutic outcomes. In assessing the fidelity of a treatment (i.e., the degree to which a treatment is delivered as intended), three aspects have been highlighted: (a) competence (i.e., the skillfulness or quality with which the treatment is provided), (b) adherence (i.e., the extent to which the therapist acts in accordance with the treatment manual), and (c) differentiation (i.e., delivery of the intended and not other interventions; Perepletchikova et al., 2007). Of these process variables, adherence and competence have received the most empirical attention. Remarkably, meta-analytic estimates suggest that adherence and competence are not related to therapeutic outcome on average (r of .02 and .07, respectively; Webb et al., 2010). As one evaluates this literature more closely, it becomes clear that there are many important methodological choices researchers make in conducting such research. Investigators have made a variety of choices across studies, yielding a collection of studies that vary considerably in their methods and analytic approach. Because important decisions about a therapist’s ability to provide a treatment are often based on assessments of competence, we focus first on research
Depression 21
examining the relation between competence and outcome. The most commonly used measure of competence is the Cognitive Therapy Scale (CTS; Young & Beck, 1988)—a rating of competence typically made on the basis of observing a single CT session. As noted, the overall evidence for this association has been quite mixed. To our knowledge, only one study has reported a finding that competence predicts subsequent outcome in CBTs for depression (Strunk, Brotman, DeRubeis, & Hollon, 2010). In a sample of 1,247 patients treated by 43 therapists as part of the British government’s IAPT program, they did not find a significant correlation between CBT competence and outcome (Branson et al., 2015). However, when they compared the outcomes of the caseloads of the most and least competent therapists, they did find a small difference in favor of the most competent therapists with regard to improvement in symptoms of anxiety. To place this evidence in context, it is important to consider the factors working against the detection of a competence-outcome association. There have been major concerns raised about the reliability of CTS competence ratings (Jacobson & Gortner, 2000; Schmidt et al., 2018). In addition, variability across patients in the degree to which high-quality therapy is required (or sufficient) to produce a positive outcome likely impacts estimates of the relationship between competence and outcome. In one analysis, therapist competence was more strongly related to outcome among patients whose characteristics suggested that they would be more difficult to treat (Strunk, Brotman, DeRubeis, & Hollon, 2010). Despite the overall lack of evidence for a relation between adherence and outcome, several studies of adherence to cognitive strategies in CT for depression specifically predict subsequent therapeutic gains. In two studies of CT, when therapists in an early session of CT utilized more of a set of techniques termed “concrete” (i.e., problem-focused), patients went on to experience greater overall symptom reduction (DeRubeis & Feeley, 1990; Feeley et al., 1999). Following these studies, a factor analysis in a larger sample suggested three adherence factors in CT for depression: cognitive methods, behavioral methods/homework, and negotiating/structuring (Strunk et al., 2012). Using this structure in a study of session-to-session changes across early sessions of CT, therapist adherence to cognitive methods (i.e., techniques intended to directly facilitate cognitive change) predicted session-to-session symptom improvements (Strunk, Brotman, & DeRubeis, 2010). Additional analyses suggested that this association was not accounted for by any stable patient characteristics (Sasso et al., 2016). Consistent with these indications of the importance of cognitive strategies in CT, therapists’ use of Socratic questioning was found to predict early session-to-session symptom change among trainees providing CT (Braun et al., 2015). Although methodological differences across studies complicate the comparison of findings (Pfeifer & Strunk, 2015), there have now been several studies suggesting that use of cognitive methods or concrete techniques predict subsequent symptom change. Perhaps the greatest controversy regarding the process of change in cognitive behavioral treatments has been over the role cognitive change plays.
22 Strunk, Pfeifer, and Ezawa
Although Beck hypothesized that CT achieves its effects through cognitive change, some have interpreted the available evidence as indicating that CT does not achieve its effects through cognitive change (Kazdin, 2007; Longmore & Worrell, 2007). The finding that BA achieves comparable symptom reduction to using both behavioral and cognitive interventions (Jacobson et al., 1996) has been taken to suggest that cognitive strategies do not impact symptoms. However, it is possible that cognitive change serves as a mechanism of therapeutic change in one treatment and a byproduct of another change process in the other treatment. Alternatively, cognitive change may serve as the mechanism of change in both treatments. The model underlying CT does not suggest that cognitive change is a mechanism only in CT (see Lorenzo-Luaces et al., 2015). There is evidence consistent with the view that cognitive change may serve to reduce depressive symptoms in CT. Of course, a great deal of research has documented the relation of reductions in negative cognition and depressive symptoms in a wide variety of psychotherapies. However, this might be accounted for by cognitive change serving as a mechanism of therapeutic change or as a byproduct of another mechanism. One of the most compelling findings consistent with the possibility that cognitive change may serve as a mechanism has been obtained in the context of studies examining sudden gains. Sudden gains are large and lasting improvements in depressive symptoms that occur in a single between-session interval. In two separate studies, the sessions preceding sudden gains have been found to be characterized by a high incidence of statements by the patient indicating cognitive changes (Tang & DeRubeis, 1999; Tang et al., 2005). Another key finding in support of the importance of cognitive change involves cognitive reactivity (i.e., patients’ endorsement of negative beliefs following a negative mood induction). Segal et al. (2006) found that patients treated with CT achieved lower levels of cognitive reactivity than those treated with medication, and cognitive reactivity predicted subsequent risk of relapse across both groups. Thus, the evidence does not show that cognitive change is not a mechanism of CBTs. In fact, key evidence is consistent with the possibility that cognitive change may serve as a mechanism of change.
CONCLUSION Cognitive behavioral approaches to treating depression have wielded a tremendous influence in recent decades. These treatments not only significantly reduce acute symptoms to the same degree as antidepressant medication, but they also provide an enduring effect of reduced risk of relapse that surpasses discontinued medication. The cognitive behavioral tradition occupies an honored position as one of clinical psychology’s most well-known and frequently studied models of psychological science, and today it is arguably one of the foremost representatives of the field to the public. The compelling and timeless theoretical rationale, emphasis on collaborative empiricism between therapist
Depression 23
and patient, and basis in well-developed scientific principles are essential elements of the success and popularity of cognitive behavioral treatments. Key issues for the future research include further refining our understanding of how these treatments work and what therapeutic strategies best engage key mechanisms for different patients, better specifying how these treatments can be integrated into a comprehensive model of care, and identifying how these treatments can best be disseminated to meet the tremendous societal need for such evidence-based treatments. Given the greater burden of depression observed in underserved and minority communities, cross-cultural applications of established treatments are an especially important area of focus (Miranda et al., 2003). CBTs have played, and are continuing to play a vitally important role in promoting the well-being of millions of people with depression around the world and are likely to continue doing so for many years to come.

nxiety is a common human emotion and a normal and adaptive part of everyday experience. Anxiety can optimize functioning under pressure, and scientists have long known a moderate anxious arousal improves performance for well-learned, simple tasks (Yerkes & Dodson, 1908). For instance, consider an athlete who performs best in a big game or a student who shows improved math exam scores following cognitive reappraisal (i.e., reframing the exam as an opportunity changes one’s emotional response to it; Jamieson et al., 2010). Athletes and performers use their anxious energy to improve their performance; in fact, those who accept anxiety-provoking events as challenges gain energy from their anxiety and improve their performance (Strack et al., 2017). For most people, anxiety is part of everyday life. Others experience anxiety that is severe or persistent, and the anxiety leads to difficulties with personal relationships or interferes in their ability to function at work or in school. About 40 million U.S. adults were diagnosed with an anxiety disorder in the previous year (Kessler, Chiu et al., 2005). Anxiety that causes life interference, emotional distress, and impaired functioning is often indicative of an anxiety disorder diagnosis (American Psychiatric Association [APA], 2013).1 Several revisions in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) impacted the classification and treatment of anxiety disorders. First, in contrast to prior editions (that were not developmentally based), the DSM-5 anxiety chapter reflects a developmental approach Clinical examples are disguised to protect patient confidentiality.

with disorders now sequenced according to typical age at onset. Second, separation anxiety disorder and selective mutism are newly classified as anxiety disorders in the DSM-5, whereas in prior editions they were among disorders that first appear in childhood. Also, obsessive-compulsive disorder and posttraumatic stress disorder are in new DSM-5 chapters (and no longer classified as anxiety disorders). Third, because panic attacks are a common occurrence accompanying anxiety disorders and other psychological and medical disorders, they are now specifiers in the DSM-5, as appropriate. Finally, the 6-month duration applies for most anxiety disorders. Other changes include changes to increase diagnostic precision including disorder-specific rating scales, changes in morbidity overlap, and efforts to characterize severity and course tracking. Our chapter reviews DSM-5 anxiety disorders and critically examines their treatment using cognitive behavioral therapy (CBT). Following an overview of chief symptoms and epidemiology, we review the methods, theory, and purported mechanisms of change underlying CBT for anxiety disorders. Metaanalyses and efficacy of treatments are reported, as available. We conclude with dissemination and treatments as applied to diverse populations, and we provide statements for application of anxiety treatment and conscientious clinical practice.
GENERALIZED ANXIETY DISORDER Worry is uncertainty or anxiety about real or perceived difficulties. It is adaptive when it helps a person prepare for the future or possible threats. For some individuals, however, worry is maladaptive when it is chronic, disproportionate, and unreasonable. When worry becomes excessive (i.e., occurring on more days than not for at least 6 months) and is difficult to control, a diagnosis of generalized anxiety disorder (GAD) is assigned. GAD impairs quality of life and role functioning and leads to high health care costs (Bereza et al., 2009). Excessive anxiety and worry are the chief cognitive symptoms, and three of six associated symptoms (e.g., restlessness, irritability, sleep disturbance) characterize the physical symptoms of GAD. Individuals with GAD may experience symptoms partly due to an overlap in genetic vulnerability and biological vulnerability related to disturbances in GABA, serotonergic, and noradrenergic systems (Nutt & Malizia, 2001). In other words, those prone to GAD may have an inherited underlying propensity toward neuroticism (Hettema et al., 2004). The lifetime prevalence of GAD is approximately 5.7%, and about 3% of the population suffers from GAD in any 12-month period (Kessler, Chiu, et al., 2005). GAD is a chronic disorder with few patients remitting over a 12-year period (42%), and nearly half of individuals who remit show recurrence (Bruce et al., 2005). GAD is approximately twice as common in women than in men. A large percentage (60% to 80%) of individuals with GAD remember being anxious all their lives, and they report a slow, insidious onset (Roemer et al., 2002; Wells & Butler, 1997). Some research documents the development of
Cognitive Behavioral Therapy for Anxiety Disorders 35
GAD in older adults for whom GAD is the most common anxiety disorder (e.g., Mackenzie et al., 2011). Cognitive behavioral theory explains why individuals with chronic worry and GAD show common characteristics that maintain the cognitive and behavioral cycle of worry. Among these attributes are a tendency to catastrophize negative events, a low tolerance for uncertainty, an iterative style of and difficulties with problem solving, worry about worry, and other behavioral and cognitive strategies that may be detrimental and sustain the cycle of worry (Borkovec, 1994). GAD is associated with an attentional tendency to interpret ambiguous situations as threatening (Hayes et al., 2010) and to overestimate the probability of negative events. According to the cognitive avoidance model of GAD (Borkovec et al., 2004), clinically significant worry may function as an avoidance behavior in an effort to (a) prepare for or prevent bad events from happening or (b) reduce emotional response (i.e., avoiding feared images or autonomic arousal). In other words, worry may function as avoidance by subduing upsetting imagery and associated autonomic activation. This creates a negative reinforcement cycle (i.e., upsetting imagery followed by worry as cognitive avoidance to escape the possible attentional threat of negative information). Studies have not yet supported all aspects of this model, but the evidence indicates that worry produces short-term relief from the physiological responses to stress (i.e., negative reinforcement). Behavioral avoidance is also a GAD feature that reinforces anxiety and increases the cycle of worry. Worry behaviors include procrastination (e.g., excessive list-making), overpreparation (e.g., arriving at appointments excessively early), and checking behaviors (e.g., reassurance seeking). Intolerance for uncertainty, a cognitive bias that affects how a person perceives, interprets, and responds to uncertain situations, is also a characteristic among those with GAD (Anderson et al., 2012). An intolerance for uncertainty is a common factor observed among other emotional disorders as well (Boswell et al., 2013). Treatment The most well-studied and empirically supported psychotherapy for treating GAD is CBT. In CBT, patients are taught to identify anxiety-related thoughts, images, and beliefs and then search for evidence to create alternative, less anxiety-arousing assumptions or interpretations. As part of homework and experiments, patients test alternative viewpoints and are taught coping methods. One primary goal in CBT for GAD is to interrupt the negative, selfperpetuating cycles of worry and related behaviors. The excessive, uncontrollable worry about future events and outcomes, which is a key feature of GAD, may serve an avoidance function by using worry to reduce arousal to feared outcomes (i.e., negative reinforcement). Patients learn techniques in controlled breathing and progressive relaxation training, visualization, or mindfulness to encourage return of normal parasympathetic nervous system functioning over time.
36 White and Cheung
CBT for GAD is multimodal and includes psychoeducation, relaxation training, identification and monitoring of worry cues/triggers, cognitive restructuring, and exposure (i.e., imagined or feared images, anxiety-provoking situations, subtle avoidance behaviors, and in vivo, as needed). Psychoeducation introduces patients to the model of factors that perpetuate GAD, informs and corrects misconceptions about anxiety and worry, and educates patients about the causative factors of pathological worry. Relaxation training is significant for GAD patients who experience reduced autonomic functioning and high muscle tension. Patients eventually learn cue-controlled relaxation by progressive muscle relaxation after brief deliberate tension exercises (i.e., 12-muscle group, 8-muscle group, and 4-muscle group). Breathing exercises are often paired with the progressive relaxation treatment. This initial step in CBT is to provide patients with regular practice to reduce overall physiological arousal and a method to help calm anxious arousal. The Socratic questioning method is used to identify and modify thoughts and appraisal in GAD. Excessive worry about future events, a key feature of GAD, may serve as an avoidance function by reducing arousal to feared outcomes (i.e., negative reinforcement). Thus, early in treatment, patients learn to identify anxious thoughts and worry triggers. Worry triggers arise from the environment, thought content (i.e., image, belief), or behavioral or physiological events. Patients detect worry triggers and discern the different characteristics of worry (i.e., cognitions, behaviors, and physiology). This process encourages patients to objectify their experiences and identify ways to interrupt the cycle of worry. The purpose of this treatment component is (a) to disrupt the negative, self-perpetuating cycle of worry and worry behaviors and (b) to seek evidence to create rational, less anxiety-arousing alternatives to each worry, assumption, or interpretation via cognitive restructuring. During this process of cognitive restructuring, individuals generate alternative hypotheses, identify and modify fearful thoughts, and consider realistic alternatives. The aim is to help the patient tolerate and accept probable, authentic alternatives to their original worry-based concerns and assumptions and then test out the alternatives to the extent possible. Treatment of GAD includes repeated exposure to situations that are avoided or endured with excessive preparation or checking behaviors. Imaginal and in vivo exposure techniques help individuals notice avoidance behaviors and help them become comfortable with their most feared outcomes. For example, if a retired patient avoids watching/reading the financial news for fear it will trigger unwanted fears about personal financial collapse (i.e., bankruptcy, loss of retirement savings), exposure to financial news channels and reading business pages would be an important exposure. After the exposure, the patient can use cognitive restructuring to examine the feared outcome (e.g., bankruptcy) and cognitive errors. For instance, worry may involve probability overestimation (e.g., what is the likelihood of the feared outcome? What are alternative possibilities? Is it 100% likely or less?) and decatastrophizing (e.g., if the feared outcome happened, could I cope? Have I ever dealt a difficult challenge before? How did I cope in the past? How did I manage a difficult circumstance in the past? What steps would I take if this happened?). Part of the therapeutic
Cognitive Behavioral Therapy for Anxiety Disorders 37
process in exposure and cognitive restructuring is to increase acceptance of alternative possibilities and increase tolerance for uncertainty. An intolerance for uncertainty results from negative thoughts about uncertainty and its consequences, and it involves how a person interprets and responds to uncertain situations and their consequences. Work by Michel Dugas and his colleagues has shown that intolerance of uncertainty is common among those with GAD. In a multiple baseline study, treatment response for GAD treatment using CBT was related to change in intolerance for uncertainty (Dugas & Ladouceur, 2000). Efficacy CBT has been the most studied psychological treatment and is a first-choice intervention for GAD. CBT for GAD is efficacious, as shown in several metaanalyses (Cuijpers et al., 2014; Hofmann & Smits, 2008b; Mitte, 2005). Effect sizes for CBT for GAD are large (ES = 1.8) compared with control conditions, including wait-list control and placebo control (ES = 0.44 to 0.57; Hofmann & Smits, 2008b), and treatment effects from CBT persist for up to 6 to 12 months (Mitte, 2005). Comparative trials show CBT is more effective than supportive therapy (Borkovec & Costello, 1993; Borkovec & Mathews, 1988) and psychodynamic therapy (Leichsenring et al., 2009). Response rates range from 44% to 71% (x = 56%), and treatment attrition is approximately 10.7% (Newman et al., 2011; Westra et al., 2009; Wetherell et al., 2011). Few dismantling studies have examined which components are essential to the efficacy of CBT for GAD. However, some research has found individual components to be comparatively more effective. A few randomized trials have shown that progressive relaxation training did not differ from CBT at posttreatment (Hayes-Skelton et al., 2013; Siev & Chambless, 2007). Cognitive therapy (CT) may be effective as an independent component for GAD (Borkovec et al., 2002) compared with non-CT controls, but the effects were weaker in comparison (d = 63). Finally, studies have successfully modified patient attentional bias using computerized training programs (Amir, Beard, Burns, & Bomyea, 2009), yet these studies have smaller effect sizes and did not use standard CBT. GAD commonly co-occurs with major depression. Treatment response is less than optimal for patients who experience GAD in the context of major depression. This is because these disorders share worry and ruminative features, also known as negative self-referential processing. A recent study compared CBT plus principles from affect science with an attention control condition; the combined CBT condition outperformed the attention control condition at the end of treatment, as evidenced by large effect sizes for both GAD and major depression (Mennin et al., 2018). Patients receiving the combined treatment maintained response at a 9-month followup. Considerations Clinical trials for CBT for children and adolescents with GAD generally suggest efficacy, including a computer-assisted intervention (Khanna & Kendall, 2010).
38 White and Cheung
Rates of response of generalized worry in later life compared with CBT with younger adults is slightly lower (Stanley et al., 2002). Results by Wetherell et al. (2013) found the sequence of antidepressant medication augmented by CBT led to worry reduction in the short term, and continued medication prevented relapse. However, for many older adults, CBT allowed sustained remission without requiring long-term pharmacotherapy late-life GAD. In a separate group treatment study, CBT was similarly efficacious and included interaction and opportunity for self-disclosure (Wetherell et al., 2003). Treatment components include memory enhancers (e.g., reviews, homework reminders), learning aids (e.g., acronyms) to compensate for reduced memory abilities, and a slower pace of CBT sessions.
PANIC DISORDER AND AGORAPHOBIA Panic attacks are characterized by sudden and acute surges of fear or discomfort that reach peak levels of intensity within several minutes of onset. Unexpected panic attacks occur in the absence of obvious cues, whereas expected panic attacks are elicited by situational determinants. Anxiety involves the activation of the sympathetic nervous system, triggering fight or flight reactivity. Ergo, episodes of panic are accompanied by physical symptoms (e.g., palpitations, shallow breath, chest pain, nausea, dizziness, chills or heat sensations, and paresthesia [i.e., numbness or tingling sensation]) that may resemble myocardial infarction, as well as cognitive symptoms such as depersonalization, derealization, and fears of going crazy or dying (APA, 2013). A minimum of four symptoms are required for a full-blown panic attack, whereas fewer than four symptoms specify a limited-symptom attack. Experiences of panic are common, and a panic attack alone does not qualify an individual for panic disorder (PD). A diagnosis of PD is assigned when an individual experiences recurrent panic attacks, persistent concern about the occurrence or consequences of future attacks (e.g., fears of a heart attack, losing control), and significant behavioral change for a minimum of 1 month. Epidemiological studies estimate the lifetime prevalence of panic attacks and PD in the general population is 13% and 1.7%, respectively (de Jonge et al., 2016; Weissman et al., 1997). Within the United States, rates of lifetime occurrence are higher, at about 3.7%, with women showing two-fold greater risk than men (Eaton et al., 1994; Kessler et al., 2006). Symptoms typically emerge in early adulthood with modal onset between 21 and 23 years of age. A central feature of PD is anxiety sensitivity, or the belief that interoceptive sensations reflect signs of impending harm (Reiss et al., 1986). In efforts to avoid the real or imagined consequences of panic, individuals are hypervigilant for changes in physiological arousal and maintain urges to avoid or escape situations and behaviors that would likely elicit panic. Aversion to somatic sensations associated with anxiety and panic is known as interoceptive avoidance and may include abstinence from arousal-inducing experiences (e.g., strong emo-
Cognitive Behavioral Therapy for Anxiety Disorders 39
tion, caffeine, physical exercise, sexual activity; White & Barlow, 2002). In a subset of individuals with PD, fear and avoidance across multiple situations may reveal an independent, secondary DSM-5 diagnosis of agoraphobia. In rare cases, individuals with severe agoraphobia become housebound. Rates of agoraphobia are thought to be underestimated because of difficulties in seeking treatment; however, PD is highly comorbid with agoraphobia. Patients engage in safety behaviors to prevent feared outcomes and to promote a sense of security (White & Barlow, 2002). Examples of safety behaviors include monitoring the proximity to certain locations (e.g., bathrooms, hospitals), carrying objects (e.g., rosary beads, pill bottles, lucky charms), and attaching “safety” to a support person (e.g., family member, therapist). Interoceptive avoidance minimizes exposure to the conditioned stimulus while safety behaviors mitigate the intensity of the conditioned response. Despite providing immediate relief from panic attacks and panic-like symptoms, both emotion regulation strategies perpetuate distorted beliefs and prevent fear extinction. Thus, CBT for PD includes exposure to physiological arousal and elimination of safety behaviors. Treatment and Efficacy CBT is a benchmark treatment for PDs (Barlow et al., 2000). Efficacy studies show CBT treats PD better than placebo, applied relaxation, and supportive therapy (Barlow et al., 2000; Clark et al., 1994; Craske, Maidenberg, & Bystritsky, 1995). Two of the most well-established and supported forms of CBT for PD are Clark’s CT (Clark, 1986) and Barlow and Craske’s Panic Control Treatment (PCT; Barlow & Craske, 2007). Both short-term treatments involve psychoeducation on the components of anxiety and panic, identifying and restructuring misinterpretations about physiological sensations, and exposure therapy. Dismantling studies have enabled the microanalysis of specific treatment components, and the results for breathing retraining (e.g., training a patient to help decrease hyperventilation symptoms) are mixed. One study found breathing retraining to be nonessential and iatrogenic to outcome. In a dismantling study by Schmidt et al. (2000), CBT with breathing retraining yielded a poorer outcome compared with CBT without breathing retraining. For most patients, breathing retraining is an avoidance behavior that prevents an individual from experiencing the full extent of their physical symptoms. For some patients, breathing retraining can be an experimental procedure (i.e., not a treatment technique). It can help patients test whether breathing (or overbreathing) plays a role in panic attacks. During CBT, patients learn panic attacks are harmless and time-limited symptoms, and breathing is an autonomic nervous system process that does not need (re)training. From a cognitive perspective, panic is thought to arise from interpretations of somatic sensations as signs of imminent harm and loss of control. Autonomic activation enhances physiological arousal, reinforcing distorted cognitions in a positive feedback loop. For instance, perceptions of an elevated heart rate may prompt erroneous beliefs about an impending heart attack. These thoughts
40 White and Cheung
increase fear and, in turn, produce a faster heart rate. To the patient, this may serve as evidence to confirm the initial hypothesis that “something terrible is about to happen.” Individuals with PD may vigilantly scan the body for somatic sensations that indicate threats of serious physical and mental harm. In CT, exposures serve to elicit cognitive change through the modification of erroneous assumptions. Randomized controlled trials have shown the efficacy of CT over supportive therapy (Beck et al., 1992), applied relaxation, and imipramine (Clark et al., 1994). Moreover, Clark et al. (1999) found that a brief five sessions of CT was as efficacious for PD as receiving the full course of CT. PCT emerged from Barlow’s (1988, 2004) landmark contribution that integrated a “triple vulnerabilities” model of anxiety and encompassed behavioral principles of associative learning. The development of PD is attributed to interoceptive conditioning resulting in anticipatory anxiety or fear of fear (Goldstein & Chambless, 1978). Panic attacks are likened to false alarms, whereby autonomic arousal is activated in the absence of a true threat. Through classical conditioning, initial interoceptive and exteroceptive (situational) cues pair with intense fear; subsequent experiences of physiological arousal prompt the conditioned response of acute anxiety or panic attacks. In PCT, exposure helps to extinguish the feared response and to gather evidence to disconfirm distorted thoughts (i.e., probability overestimation, catastrophizing). Research points to an advantage of in vivo exposure over imaginal exposure. Exposure exercises provide the opportunity for patients to gather information that may disconfirm misappraisals about themselves in situations they fear. PCT integrates skills in exposure (i.e., situational and interoceptive) and cognitive restructuring over time. PCT reduces PD, and its effects are better than supportive therapy, progressive muscle relaxation, and wait-list controls (Barlow et al., 1989; Craske, Maidenberg, & Bystritsky, 1995). An abbreviated version of PCT (i.e., four to six sessions; Craske, Maidenberg, & Bystritsky, 1995) and a brief computer-assisted course of PCT have been effective in PD treatment (Newman et al., 1997). In one study, researchers tested a maintenance CBT aimed at reinforcing treatment gains and preventing relapse in patients who responded to PCT; the maintenance CBT produced lower relapse rates and reduced work and social impairment compared with an assessment-only condition at a 21-month follow-up (White et al., 2013). For patients who failed to respond to an initial course of CBT (i.e., PCT nonresponders), they experienced greater improvement in PD symptoms by switching to SSRI treatment compared with those who received continuation CBT (Payne et al., 2016). In summary, numerous controlled studies show the efficacy of CBT (both PCT and CT) to treat PD; and both approaches yield 70% to 80% panic-free states and high end-state functioning. One meta-analysis compared treatment outcomes of combination CBT and antidepressant treatment to monotherapies and found that combination treatment outperformed both medication alone and psychotherapy alone regardless of antidepressant type and comorbid diagnoses (Furukawa et al., 2007). At 6 months posttreatment, combination therapy was comparable to psychotherapy alone and superior to medication only. These
Cognitive Behavioral Therapy for Anxiety Disorders 41
results are consistent with research citing the enduring effects of CBT in preventing panic relapse following discontinuation of medication (Choy, Peselow, et al., 2007; Hofmann et al., 2009). Finally, a recent dismantling review and component network meta-analysis of the components of CBT for PD found support for face-to-face CBT and interoceptive exposure, but data were not supportive of muscle relaxation and virtual-reality exposure (Pompoli et al., 2018). Considerations Given the somatic nature of PD, many individuals experiencing panic attribute their symptoms to an organic (e.g., heart attack) rather than psychological etiology. Thus, a vast majority of individuals with panic attacks and PD present to primary care physicians and emergency departments (Katerndahl & Realini, 1995; Wang et al., 2005), resulting in the need for interdisciplinary collaboration and integration of evidenced-based treatments of PD in these settings. Efforts to disseminate CBT show promise. In primary care, CT (Grey et al., 2008) and combination CBT with pharmacotherapy (Roy-Byrne et al., 2005) were more effective than treatment as usual in reducing panic symptoms. Researchers trained therapists in a managed care setting to deliver PCT to their patients (Addis et al., 2006); among treatment completers, patients in the PCT group showed a greater reduction in panic severity and agoraphobic avoidance relative to those in treatment as usual. These studies provide support for dissemination of CBT with brief therapist training, thus increasing the proportion of patients with PD receiving evidence-based treatment in medical settings. Clinical Example Lucia was a 33-year-old, married woman raising two young sons and working part time in education. She came for treatment because of anxiety and panic attacks that had increased in the past 2 years. Two years ago, during her second pregnancy, she experienced a sudden heart palpitation. Lucia recalls feeling terrified that she was dying from a heart attack and that her heart symptoms would harm her unborn child. She was tested and released from an emergency department; outpatient cardiology later evaluated her, and she received a diagnosis of mitral valve prolapse (MVP). The mitral valve (between the heart’s upper and lower left chambers) was not closing smoothly during her pregnancy. Lucia recalls these stressful medical events coinciding with her first full-blown panic attack. A general practitioner referred her for treatment of health anxiety. Assessment Phase Lucia’s therapist was a licensed clinical psychologist. A central tenet in CBT is to cultivate a strong therapeutic alliance and conduct a culturally informed functional behavioral analysis. To build rapport and assessment, a detailed interview
42 White and Cheung
and self-report battery were completed. The semi-structured interview, Anxiety Disorders Interview Schedule-5L, comprised a diagnosis of anxiety, mood, trauma, and other related disorders. Panic attacks are pervasive and occur across anxiety and other disorders, so differential diagnosis can be difficult. Details collected during the interview and questionnaires helped the therapist arrive at a diagnosis and adapt treatment for Lucia’s individual presentation. Diagnostic Impressions Lucia’s clinical presentation was consistent with a principal diagnosis of Panic disorder (F41.0) and Agoraphobia (F40.00). Medical history was significant for Mitral valve prolapse (134.1) and Asthma, unspecified and uncomplicated (patient-reported). Medications included the following: generic birth control pill (QD) and Advair (inhaler, PRN). Scores on the Panic Disorder Severity Scale and on the Albany Panic and Agoraphobia Questionnaire showed elevated panic attack severity and high situational avoidance and interoceptive fears. On the Anxiety Control Questionnaire, scores suggested low perceptions of anxiety-related dimensions of Emotion, Threat, and Stress control. Scores on the Beck Depression Inventory-II suggested a depressive mood state. Self-report data were consistent with diagnostic interview impressions. Medical Evaluation The therapist recommended Lucia get a medical evaluation during the assessment phase. Some medical conditions may underlie or exacerbate PD, including cardiac disorders (e.g., heart disease, MVP), hormone and metabolic disorders (e.g., diabetes, changes in blood sugar including hypoglycemia), and respiratory disorders (e.g., chronic obstructive pulmonary disease, asthma, allergies); thus, medical evaluation was necessary. Lucia provided the therapist with a signed medical release for communication between the therapist and Lucia’s cardiologist. Following concise discussion between the therapist and cardiologist about Lucia’s cardiovascular health issues (MVP and current health), the cardiologist provided a written letter stating Lucia was qualified for full participation in CBT, including physical activity. Case Conceptualization Lucia’s panic attacks were characterized by symptoms including a pounding and racing heart, hot flush, throat tightness, shortness of breath, and a sense of impending doom. Her main fears were of a loss of control or death, particularly that she may lose control when the panic is unexpected (i.e., when she is driving, when she is sleeping) or she may die (i.e., from a heart problem). Average frequency was three full-blown panic attacks and two to three limited-symptom attacks. Each attack lasted from a few seconds to 15 minutes. Antecedents to her panic attacks were situational (expected) and internal (unexpected), and Lucia spent 70% of the day apprehensive about panic attacks. Internal antecedents included heart rate variations, heart flutter sensations associated with MVP, racing heart, lightheadedness, hunger, thoughts of hospitals, thoughts of open spaces, aloneness, thoughts of not being able to handle a heart attack, and
Cognitive Behavioral Therapy for Anxiety Disorders 43
fears she could not do this much longer. Situational antecedents included driving on freeways, driving outside safe areas, being alone (at night), physical activity (that provokes cardiovascular activation), and social events (when escape is difficult). Lucia’s cognitive misappraisals included the belief that because the panic attack symptoms resembled the symptoms of a heart attack, she feared she was dying of a heart attack. Some of Lucia’s other cognitive misappraisals included beliefs that the panic attacks would make her lose control and behave erratic or crazy. Behavioral reactions to panic attacks include situational avoidance and escape behaviors. Lucia’s situational avoidance included avoidance of all longdistance driving, night-time driving, being at home alone, most social events, and exercise and cardiovascular physical activities. Her escape behaviors included pulling off to the side of the road, leaving social events early, and calling safe others (her husband and mother). Safety behaviors included wearing a smart watch with cardiac app, pulse checking, excessive planning, air conditioning, and a water bottle. As an example, to cope and reduce her anxiety and fear or when she felt threatened, Lucia would turn up the air conditioning and keep water near. These safety behaviors reduced anxiety in the short term (i.e., less warmth, perspiration, activation, dry mouth), but safety behaviors prolonged her fear and anxiety of nonthreathing situations in the long term. Lucia’s husband had been compassionate but concerned; his support had diminished as the children grew older with more needs. Lucia was working part time, but she reduced her workload. Lucia described difficulty concentrating and sleeping; she felt tearful and sad much of the time. Her low mood included episodic hopelessness, and she had a hard time expressing herself and accomplishing tasks at work and home. Anxiety and panic interfered with Lucia’s social and occupational functioning. Treatment Phase It was mutually agreed to begin evidence-based CBT for PD and agoraphobia, using a modified version of PCT. The goal of PCT was to foster within Lucia the ability to identify and correct maladaptive thoughts and behaviors that start, maintain, and exacerbate her anxiety, panic attacks, and avoidance. To achieve this goal, treatment combined psychoeducation, cognitive techniques, and exposure techniques. Early sessions included psychoeducation and skill-building components. Lucia learned about the fear response (its nature and functions), its nervous system substrates, and how natural fear enhances our ability to survive and compete in life. Panic attacks are inappropriate fear reactions that arise from spurious but otherwise normal activation of the body’s fight-or-flight nervous system; like any fear reaction, they encourage immediate defensive action and a search for the source of the threat. Like others with panic, when Lucia could not find a source of threat, she looked inward and interpreted the symptoms as signs that something was wrong with her (e.g., “I am dying of a heart attack”). Lucia wondered if she was interpreting her heart symptoms as signs that something was wrong with her; she worried, “If my heart beats too hard or flutters too much, will my heart break or give out on me?” The
44 White and Cheung
therapist and Lucia discussed the integrative model of PD, the three-component model of anxiety (cognitive, behavioral, and physical), a rationale for treatment, and self-monitoring. The next sessions focused on evaluating some of Lucia’s thoughts about of anxiety and fear. Lucia was global and nonspecific in refuting or countering her anxious thoughts. Lucia had two kinds of anxious thought processes: probability overestimation (i.e., Lucia’s prediction that a panic attack may cause her heart palpitations that lead to her losing control of the car and crashing), or overestimating the likelihood of a negative outcome, and catastrophic thinking (i.e., if Lucia were to collapse due to a panic attack, she perceived the consequences would be insufferable and she would die alone). In CBT, she learned to gather facts and evidence to test and refute her feared predictions and their consequences. Based on her past experiences and critical thinking skills, Lucia determined the likelihood (or probability) of a feared event. Further, if the worst outcome occurred, she allowed herself to think about how she would cope with the consequences. To provide clinical context for the cognitive work and to set the stage for exposure, a preliminary fear and avoidance hierarchy (FAH) was drafted. Lucia and her therapist spent several weeks conducting behavioral experiments. Principles and techniques of exposure were discussed, and the interoceptive experiments were modeled by the therapist and conducted in session. Certain physical sensations (like tachycardia, dizziness, smothering) are deliberately provoked by each exercise (like breathing through a straw, spinning, vigorous running for 30 to 60 seconds). Using prediction testing (a component of CT), Lucia would test some of her feared predictions. At the 30-second mark (the halfway point of the 1-minute exercise) when she was running in place vigorously, Lucia stopped in a full-blown panic attack. She sat down, signaling with her hands that she was upset. The therapist could see she was blinking tears, sweating, and unsteady. The therapist asked Lucia stand up with her feet in a narrow stance (without stabilization) and without holding onto the desk. Within minutes, Lucia seemed astonished to report the panic attack had subsided. This was perhaps the most important moment in Lucia’s treatment: she was provided with disconfirming evidence that a panic attack would cause her heart to break and lead her to collapse on the floor, and she learned that when she dropped to the floor in the past during a panic attack, she had done so of her own volition, as a way of coping. Prior to conducting any trials, Lucia predicted a 65% chance that the first trial of running in place would cause her “heart to beat very rapidly and cause her to drop to the floor uncontrollably.” After completing two trials, Lucia’s predicted probability of dropping to the floor changed to 10%. As she became less fearful of in-session experimental sensations, Lucia practiced interoceptive exposures (experimental and natural) at home (e.g., caffeinated drinks, sexual activity, exercise in warmer spaces). Subjective units of distress symptom (SUDS) ratings were collected. For situational exposure, the therapist adhered to a modified version of the agoraphobia supplement to PCT. To measure treatment progress, Lucia pro-
Cognitive Behavioral Therapy for Anxiety Disorders 45
vided fear and avoidance ratings on the FAH developed early in treatment. Each situation on the FAH was rated, including duration and other relevant information (e.g., alone vs. accompanied, time of day), and situations were listed least to most difficult based on fear and avoidance ratings. One item on Lucia’s FAH was “Drive on the interstate to Exit 38B, alone, after dark.” At the end of each session, she selected one item from the bottom of the FAH to practice two to three times before the next session. Toward the end of treatment, Lucia combined internal and external cued exposures. She paired situational exposures with interoceptive exposures (e.g., exercising in a different park, watching an emotional movie at night time, consuming a caffeinated beverage while driving alone). Lucia was reluctant to induce interoceptive symptoms and conduct situational exposures. Effective exposures combined both cues to reduce the risk of later return of fear. LUCIA:
I am afraid to go to the market with my children when I feel my heart racing and palpitations from drinking coffee.
THERAPIST: What worries you about market shopping with the kids and
drinking the coffee? LUCIA:
Well, I’ve practiced market shopping with the kids a lot, and that feels okay. But if I drink coffee, I will feel very anxious.
THERAPIST: And if you feel very anxious in the market, then what? LUCIA:
I am unsure. If I feel very anxious, I might feel like I need to leave. I might need to leave in case something happens.
THERAPIST: It sounds like you might feel you need to leave. Based on what
you have learned about feelings and facts, how else might you manage the situation? LUCIA:
Well, I have learned that I can feel anxious and tolerate challenging situations. Also, feelings are real symptoms, but as we discussed, my panicky feelings are not equal to the facts in this situation.
THERAPIST: That sounds good. And it sounds like you are learning to accept
the anxiety including a fast racing heart with an awareness that you can tolerate it. Is there anything else? LUCIA:
I also know that panic attacks are not likely to cause me to die or faint. And I can ask myself: What’s the worst that can happen? I know my heart can beat very fast.
THERAPIST: And if your heart beats very fast, what does that mean? LUCIA:
I guess, it means my heart rate is going fast.
THERAPIST: This is good. You are learning to tolerate and accept anxiety and
its symptoms.

SOCIAL ANXIETY DISORDER Some individuals are shy or introverted, and this is a natural quality among the general population. However, the suffering associated with the experience of clinically significant social anxiety disorder (SAD) is more than shyness or social inhibition; the personal anguish of SAD can provoke debilitating fear of interacting with people, and the act of forming social relationships can provoke panic. The impact of severe SAD on occupational functioning and quality of life can be extensive. SAD is prevalent and characterized by an intense fear of negative evaluation from social or performance situations. Estimates show that 10% to 12% of the U.S. adult population is affected during their lives, and SAD can have a severe, chronic course leading to disability, functional impairment, and reduced quality of life (Kessler, Berglund, et al., 2005; Ruscio et al., 2008). SAD onsets in childhood or adolescence, and treatment seeking is somewhat low. Left untreated, a large proportion of individuals with SAD (70% to 80%) meet diagnostic criteria for a comorbid diagnosis that onsets subsequent to the SAD diagnosis; in community samples, the common comorbidities are agoraphobia, major depressive disorder, and substance abuse (e.g., alcohol use disorders; Schneier et al., 1992). Treatment CBT is the most studied and most efficacious treatment for SAD, as evidenced by numerous randomized controlled trials. One aim of CBT for SAD is to identify and modify maladaptive cognitions accompanying social situations. Another aim is to target and reduce behavioral factors that maintain avoidance during SAD. Several theoretical models support evidence-based CBT approaches. According to one model by Rapee and Heimberg (1997), when exposed to social situations, individuals with SAD fear they are in danger of acting inept or undesirable and thus their actions would have negative personal consequences (i.e., social rejection, loss of status). Therefore, when they are in social situations, they are attentive for cues that signal the realization of their fears. They look for sources of negative scrutiny (real or imagined) and maintain a negative view of how they appear to others by attending to the negative cognitive, behavioral, and affective cues of their anxiety. Patients with SAD observe and monitor their physiological processes (e.g., increased heart rate, blushing sensations), and this attentional shift leads to a negative self-concept (Wells et al., 1995). Furthermore, patients then engage in overt (i.e., choosing a written presentation over an oral presentation) and subtle safety behaviors (i.e., wearing a scarf or turtleneck sweater to hide neck flushing) to provide a sense of short-term anxiety reduction. In the long term, however, safety behaviors prolong and maintain anxiety because they prevent the individual from testing the feared outcomes. Hofmann (2007) posited that individuals with SAD fear social situations partly because of a cycle of undefined expectations for performance, increased self-focused attention, and complex cognitive processes including an
Cognitive Behavioral Therapy for Anxiety Disorders 47
exaggerated probability of a negative outcome of a social situation and a view of their social skills as inadequate. Evidence-based CBT begins with psychoeducation about normal social worries (i.e., the adaptive, shared anxiety that is part of the human condition and which is unnatural to eradicate completely) versus problematic social anxiety (Hope et al., 2010). Patients also learn about the three-component model of anxiety (i.e., cognitive, behavioral, and physiological). The therapist and patient discuss the costs and benefits of treatment success (e.g., less relationship dependency). Factors thought to be related to the patient’s development and the onset of social anxiety include genetics, inherited biological sensitivity, family factors, and social learning history. Early social experiences are explored, and any negative, maladaptive thought processes are examined for signs of perceived personal shortcomings rather than logical consequences of social experiences. For example, therapists ask patients to consider how maladaptive thoughts from past events (e.g., thoughts of not fitting in with social groups, thoughts about being made fun of by peers, and anticipating feelings at social events) impact current functioning. Individuals with SAD may be anxious in social situations for any number of reasons. They may perceive a high, unrealistic social standard; they may have a desire to make an impression on others (but have self-doubt about their ability); or they may be deficient in selecting achievable social goals (Hiemisch et al., 2002). Altogether, this increases social apprehension and self-focused attention, and highly anxious individuals may overestimate the probability of a negative outcome and catastrophize the potential social costs (Clark & McManus, 2002; Heinrichs & Hofmann, 2001). Individuals with SAD view themselves as having low perceived control over their emotional responses, view the social event and its costs more negatively, and view themselves as insufficient in social skills. After social experiences, they use maladaptive tactics to manage their social anxiety, including avoidance and safety behaviors, and engage in post-event worry and rumination leading to increased social angst (Hofmann, 2007). Evidence-based CBT helps patients to detect and restructure automatic thoughts and expectations about social situations. Social anxiety is initiated and maintained partly by a person’s thoughts and expectations in a social situation. Patients are asked to contemplate how their social anxiety might change if their thoughts and cognitive preconceptions (i.e., biases) were to change. Because idealistic social standards and a failure to set realistic social goals are characteristic of SAD, patients consider the evidence for and against their specific social fears before beginning exposure therapy. For example, prior to an interpersonal exchange with a stranger, automatic thoughts might include all-or-nothing thinking (e.g., “I have to impress them”), mind-reading (e.g., “They will think I am boring”), and “should” statements (e.g., “I should be able to talk with a stranger”). After cognitive restructuring and applying rational response alternatives, exposure sessions begin. Before beginning exposure therapy, an FAH of social situations is developed based on anxiety (i.e., ranging from least anxiety-provoking social situations to most anxiety-provoking situations) and
48 White and Cheung
avoidance (i.e., ranging from least avoided social situations to most avoided social situations). Situational exposures begin with mildly anxiety-provoking situations and proceed over time to more moderately anxiety-provoking situations. The exposure situations can be conducted in vivo (e.g., talking with a store salesclerk), imaginal, or as role plays (e.g., talking with a confederate acting as a salesclerk). If assessment shows the patient deficient in social skills, CBT may include social skills training, which involves teaching social interaction skills through the behavioral techniques of modeling, reinforcement, corrective feedback, and other similar techniques. Efficacy Empirical data show CBT for SAD produces large effect sizes, is superior to no treatment control (i.e., pill placebo), and has a larger treatment impact than psychological comparison therapies (Mayo-Wilson et al., 2014). As examined in meta-analyses of randomized controlled trials, CBT has shown to be efficacious compared with placebo control, with medium to large effect sizes on social anxiety symptoms (Barkowski et al., 2016; Hofmann & Smits, 2008a). One augmentation trial examined a cognitive enhancer (i.e., D-cycloserine [D-4-amino-3-isoxazolidone; DCS]) strategy. DCS is a partial agonist at the glycine recognition site of the glutamatergic NMDA receptor. Researchers compared CBT + pill placebo versus CBT + DCS. Patients received either DCS (50 mg) or pill placebo 1 hour before each of five exposure sessions (that were part of a 12-session CBT group treatment). Results showed high response rates (73% and 79% response rates) and remission rates, and no group differences were apparent (Hofmann et al., 2013). Although CBT group treatment is considered the treatment of choice for SAD, fewer studies have shown individual CBT to outperform group CBT (Stangier et al., 2003). Evidence-based CBT for SAD provides support for either delivery mode (Hofmann & Otto, 2008). Group CBT is conducted by two therapists in 12 weekly sessions of 2.5 hours duration. Individual CBT is commonly conducted in 15 weekly sessions of 1 hour duration. As a complement to CBT, attention retraining is a promising treatment strategy. Randomized trials show that eight sessions of attention retraining to reduce attentional bias (i.e., threat cues) are superior to an attention control condition in reducing SAD symptoms (Amir, Beard, Taylor, et al., 2009).
SPECIFIC PHOBIAS Specific phobias (SPs) are the most common of anxiety disorders. According to the DSM-5, an SP is marked by a persistent fear of specific objects or situations. Phobias precipitate active avoidance of feared stimuli or are endured with extreme anxiety when faced. Intense fear may induce panic attacks and cause impairment in daily functioning (APA, 2013). The five categorical subtypes of
Cognitive Behavioral Therapy for Anxiety Disorders 49
SP are (a) animals (e.g., spiders, insects, dogs), (b) natural environments (e.g., heights, storms, water), (c) blood-injection-injury (e.g., needles and other invasive medical procedures), (d) situational (e.g., airplanes, elevators, enclosed spaces), or (e) other (e.g., choking, vomiting, loud sounds, costumed characters). Lifetime prevalence of SP is 7.4%, as reported in a cross-national epidemiological study of individuals from 22 countries (Wardenaar et al., 2017), and the prevalence of U.S. adults reporting a lifetime prevalence of SP is 13% (Kessler et al., 2012). The most common SP subtype is animals. Age of onset varies across subtypes. Whereas a younger age onset is typical for animals, enclosed spaces, and blood-injection-injury (median age of initial symptoms = 8 years; Fredrikson et al., 1996; Wardenaar et al., 2017), situational phobias are more common among older adolescents and adults (Sigström et al., 2016). Prevalence rates also vary across age, sex, and race; younger individuals, females, and Caucasians compared with Asian and Latino individuals are more likely to experience SP (Stinson et al., 2007; Wardenaar et al., 2017). The course of SP is chronic, with low rates of spontaneous remission (Goisman et al., 1998; Wittchen, 1988). The condition often co-occurs with and precedes mood, anxiety, and eating disorders (Kessler et al., 1996; Lieb et al., 2016; Trumpf et al., 2010). Despite significant distress and role impairments, many with SP do not seek treatment (Essau et al., 2000; Regier et al., 1993). Of those who use mental health services, a substantial proportion end treatment before symptoms improve. Avoidance is characteristic of anxiety disorders, and fear may prevent full engagement in treatment, as CBT involves some confrontation with the feared stimulus. Treatment and Efficacy Of the available treatments, exposure therapy has garnered the most support and is the benchmark treatment for SP (Barlow et al., 2002). Although there are many variations of exposure therapy, all interventions extend from behavioral models of fear acquisition. Through fear conditioning, a benign conditioned is paired with a stimulus with an anxiety-provoking unconditioned stimulus to elicit a conditioned fear response (Watson & Rayner, 1920). This association is (negatively) reinforced and maintained by avoidance, which prevents the individual from learning new and more adaptive responses to aversive stimuli (Mowrer, 1960b). Rachman (1978) proposed that fear may also be acquired (indirectly) through vicarious learning and information transmission. In exposure therapy, the patient is exposed to feared items on the fear hierarchy in vivo (i.e., in real life) until fear has subsided, thus reducing the strength of the conditioned response. Phobic items are presented in various contexts to generalize fear reduction. To prepare clients for in vivo exposure (and direct contact), therapists can begin with imaginal exposure. Efficacy studies boast medium to large effect sizes at posttreatment (Choy, Fyer, & Lipsitz, 2007). In vivo exposure has produced more favorable outcomes relative to systematic desensitization (inclusive of imaginal exposure with relaxation; Bandura et al.,
50 White and Cheung
1969; Egan, 1981), vicarious exposure (Öst et al., 1997), imaginal exposure (Emmelkamp, 2003), and control conditions. Advancements in technology have led to novel treatment modalities in exposure through virtual reality (VR). VR is most beneficial when in vivo conditions are costly, unpredictable, or difficult to plan. Therapists immerse patients in a contextually relevant environment that is computer simulated, allowing for gradual exposure in a controlled setting. Studies using VR exposure show it is superior to systematic desensitization (Wiederhold et al., 2002) and imaginal exposure (Emmelkamp, 2003), and is comparable to in vivo exposure (Emmelkamp et al., 2002; Rothbaum et al., 2000). However, research in this line of treatment is still in its infancy, with studies using small sample sizes. The pharmacological agent DCS offers promise to augment exposure treatment for anxiety disorders (Rodrigues et al., 2014). DCS combined with VR exposure outperformed VR exposure alone for patients with acrophobia (i.e., fear of heights; Ressler et al., 2004). DCS improves exposure treatment (compared with placebo) for SP only when administered before exposure sessions (Nave et al., 2012), but not after (Tart et al., 2013). In addition to exposure treatments, cognitive interventions of SP target attributions regarding the safety of stimulus and one’s perception of control over external events. Two core cognitive features of anxiety include catastrophizing and overestimating the likelihood of negative outcomes. Treatment involves identifying distorted beliefs associated with SP, evaluating the evidence of such beliefs, and replacing irrational thoughts with more rational probabilities of outcome. Behavioral experiments often aid cognitive strategies to test differences between expected and observed outcomes. Short intensive CT outperformed interoceptive exposure and was as effective as in vivo exposure to treat claustrophobia (Booth & Rachman, 1992; Öst et al., 2001). In fact, a single session of cognitive restructuring was effective in reducing dental anxiety (De Jongh et al., 1995). The evidence is mixed regarding the advantages of combined cognitive and exposure techniques. Cognitive procedures enhanced in vivo exposure of claustrophobia (Craske, Mohlman, et al., 1995), but they were not incrementally beneficial to treat spider (Koch et al., 2004) or flying phobias (Van Gerwen et al., 2002). However, Mühlberger (2003) found that cognitive strategies plus VR exposure (in combination) resulted in greater reduction of flying phobia symptoms when compared with CT alone. Taken together, the efficacy of CT as a stand-alone treatment or as an adjunct to exposure therapy is still unclear and may depend on the phobia subtype and the exposure treatment type. Considerations Age is a consideration in the treatment of SP. For example, gait and balance decline with age, and older adults are at an increased risk for fall. History of functioning (including motor functioning, prior falls, and head injuries) and other features associated with risk are important to differentiate logical fears
Cognitive Behavioral Therapy for Anxiety Disorders 51
from a situational phobia. Although SP is more prevalent earlier in the life course (Sigström et al., 2016; Wardenaar et al., 2017), CBT is effective across all age groups. CBT approaches have been effective in treating SP in children (Ollendick et al., 2009) and older adults (Pachana et al., 2007). Medication use is a consideration among older adults, and greater benzodiazepine use has been found among older adults who meet full or subthreshold criteria for SP (Grenier et al., 2011), which is contraindicative to exposure-based fear extinction.
SEPARATION ANXIETY DISORDER Separation anxiety disorder moved to classification as an anxiety disorder from a childhood disorder in the DSM-5. Most infants and young children show distress when separated from their caregivers. As young children develop increasing independence, they are less hesitant and feel less distress in the absence of their caregivers. For some children, however, they feel distress without their caregivers, and they develop fears that something could go wrong (e.g., fear about their health or their caregiver’s health). For a diagnosis, the DSM-5 requires that three of eight symptoms last for at least 4 weeks in children and adolescents, and the symptoms include experiencing distress when away from home or a major attachment figure. Additional symptoms include (a) worry about the well-being of the attachment figure (i.e., kidnapping, self or other getting lost), (b) an unwillingness to leave home, (c) fear of being alone, (d) unwillingness to sleep alone or outside the home, (e) nightmares, and (f) physical complaints (i.e., headaches, stomachaches). Adults with separation anxiety disorder are typically (over)concerned about their children and partners and experience marked discomfort when separated from them; separation anxiety disorder is assigned if the symptoms onset before age 18. Prevalence of this clinical condition in adulthood is underestimated partly because it was classified under “Disorders Usually First Diagnosed in Infancy, Childhood or Adolescence” in the previous DSM (Bögels et al., 2013). In community samples, the 12-month prevalence of separation anxiety disorder is 4% in children and 1.6% in adolescents (APA, 2013). The National Comorbidity Survey Replication (NCS-R) found the lifetime prevalence of adult separation anxiety disorder to be 6.6%, with the large majority (77.5%) reporting an adult onset of symptoms (Shear et al., 2006). Gender differences are less prominent in adult separation anxiety disorder; yet, across development, childhood onset is more common among females, and males are more likely to experience onset in adulthood. Although this condition is prevalent, research on presumed risk factors has focused almost exclusively on child samples. Heritability estimates point to a low-to-moderate specificity, and modest evidence supports biomarkers (i.e., carbon dioxide hypersensitivity, a peripheral-type benzodiazepine receptor binding), information-processing biases (e.g., more threat interpretations, attention selectivity), and temperamental antecedents (i.e., maternal separation anxiety, interpersonal sensitivity; Bögels et al., 2013).

Treatment and Efficacy Consistent evidence shows CBT reduces separation anxiety, and treatments involving parent training are especially effective for children and adolescents. For example, Pincus and colleagues modified parent-child interaction therapy (PCIT)—an approach in the family of CBTs—to successfully treat separation anxiety disorder in young children (Puliafico et al., 2012). Schneider et al. (2011) also used a disorder-specific CBT with parent training for child separation anxiety and demonstrated that 76% of children with separation no longer met the diagnostic criteria for separation compared with 14% of children in the wait list control condition. To improve access to treatment, researchers have also found empirical success with summer camp interventions for separation anxious children (Santucci et al., 2009). As expected, because DSM-5 only recently permitted this diagnosis in adulthood, clinical treatment studies examining separation anxiety among adults are uncommon. Relatedly, however, research has examined the impact of adult separation anxiety on treatment outcome for other anxiety disorders. In one study, patients with PD and comorbid separation anxiety symptoms were four times more likely to have a poor treatment response compared with those without separation anxiety; this finding remained significant after covarying out other prognostic indicators, including severity of anxiety and agoraphobia, number of comorbid diagnoses, duration of illness, and socioeconomic class (Aaronson et al., 2008). A separate study found that separation anxiety symptoms negatively impacted treatment response for adults in treatment for PD, SAD, and GAD (Kirsten et al., 2008).
SELECTIVE MUTISM Selective mutism (SM) is marked by an inability to speak in specific situations (e.g., school), despite competence in expressive verbal communication in other contextual settings (e.g., home). SM occurs more often in younger children and adolescents than adults. Reticence or shyness are normative in the first few months of a new environment (i.e., school), and among nonanxious children speech increases with comfort. Pathology arises when silence continues despite acclimation to new settings. A diagnosis is assigned if clinical symptoms persist for 1 month or longer and the SM impairs functioning (i.e., in educational or social settings). It can be difficult for teachers to test academic competencies, such as reading, in children with SM. Lack of verbal engagement prevents opportunities to address academic needs and clarify misunderstandings. SM can be diagnosed when the mutism is not better attributed to another condition including communication disorder, autism spectrum disorder, intellectual disability, schizophrenia, or another psychotic disorder (APA, 2013). On the basis of samples drawn from community and clinical settings, the prevalence for SM ranges from 0.18% to 1.9% (Bergman et al., 2002; Kopp & Gillberg, 1997). Like other anxiety disorders, SM is more common among
Cognitive Behavioral Therapy for Anxiety Disorders 53
females than males (Dummit et al., 1997; Kumpulainen, 2002). SM symptoms remit over time, with a mean duration of 8 years (Remschmidt et al., 2001). Symptoms typically manifest before age 5, but SM often goes undetected until formal education, as children may exhibit normal speech with immediate family members. The mean age of diagnosis is 6.5 years (Ford et al., 1998). The condition is often comorbid with separation anxiety (Steinhausen & Juzi, 1996) perhaps partly because both disorders are augmented by anxiety and avoidance in social situations. Moreover, among children with SM, 70% of first-degree relatives met criteria for social phobia, and 37% reported a history of SM (Black & Uhde, 1995). Although there is similarity, SM is distinct from separation anxiety disorder because in separation anxiety, anxiety occurs when anticipating or separating from home (or major attachment figures), whereas in SM, there is a consistent failure to speak in specific social situations despite speaking in other situations. Children with SM are often willing to engage through nonverbal communication. Treatment and Efficacy Treatment of SM remains an understudied area, with most studies using single case designs. Two trials have shown CBT is effective for SM (Bergman et al., 2013; Oerbeck et al., 2014). Behavioral models conceptualize SM as an avoidance strategy used to regulate emotions in distressing situations (Scott & Beidel, 2011). Avoidance is negatively reinforced when it reduces anxiety (Mowrer, 1960a). Early intervention is critical to successful treatment of SM. Younger children with SM may benefit more from in vivo exposure; this may be because they have difficulty with exercises involving imagery and relaxation because of their developing cognitive skills and interoceptive sensitivity (Compton et al., 2004). From the perspective of CBT conducted from a family systems perspective, SM is caused and maintained by family dynamics. Family therapy interventions seek to identify and change faulty patterns of communication. Edison et al. (2011) examined parental control across selectively mute, anxious, and nonanxious children, and they found that parents of children with SM granted less autonomy and made more power remarks compared with parents in other groups. In one case study, structural family therapy increased speech with distant relatives and friends (Tatem & Delcampo, 1995).
CONCLUSIONS AND PRINCIPLES FOR PRACTICE Mechanisms of Change Identifying mechanisms helps explain how interventions yield outcomes and helps refine treatments by identifying components of effective therapy. Extensive data support the efficacy of CBT for anxiety disorders, yet less is known about the mechanisms of change. One mechanism in GAD is decentering, the ability to observe thoughts and feelings as objective events in the mind rather than personally identifying with the thoughts or feelings. In a growth curve
54 White and Cheung
analysis, researchers found increased decentering was associated with decreased anxiety. Also, changes in decentering preceded changes in symptoms within both treatments (i.e., acceptance-based CBT, applied relaxation), which the researchers concluded may be a common mechanism of action (Hayes-Skelton et al., 2015). One study with PD patients found the effects of CBT on agoraphobia, anxiety, and panic frequency were partially accounted for by reductions in fear of fear (Smits et al., 2004). Other studies provide evidence for unique and distinct changes in self-efficacy and anxiety sensitivity, and subsequent changes in panic symptoms during CBT for PD (Gallagher et al., 2013). CBT for social anxiety modulates brain responses related to cognitive reappraisal, timing, and functional connectivity (Goldin et al., 2013). Dissemination Despite research showing high efficacy of CBT for anxiety disorders, many patients do not receive CBT for anxiety in routine clinical care. Further, even when patients receive CBT in routine care, there is evidence that the treatment is not delivered with adherence. The manualized protocols are highly effective and specific, but they are also somewhat complex and, thus, restrict dissemination. Bridging the gap between research and clinical practice has led to the development of transdiagnostic approaches. Transdiagnostic treatment approaches were developed to be applicable across the emotional disorders. The Unified Protocol is one transdiagnostic, emotion-focused CBT approach that has demonstrated treatment effects, with 73% achieving responder status and 60% achieving high end-state functioning. Results improved further at a 6-month follow-up, with 85% classified as treatment responders and 69% achieving high end-state functioning (Farchione et al., 2012). Norton’s transdiagnostic CBT has also found promising results for anxiety disorder and other emotional disorders, and data from meta-analyses show that transdiagnostic CBT is comparable to traditional CBT treatment (Norton & Roberge, 2017). Application to Diverse Populations The role of culture is fundamental to understanding relevant processes underlying anxiety and its treatment. Cross-cultural research shows that anxiety is a universal emotion and anxiety disorders likely exist in all human societies, with some differences in prevalence and form (Good & Kleinman, 1985; Kirmayer et al., 1995). Yet studies often treat culture, ethnicity, race, or country of origin as research variables that require statistical controls. To extend research in anxiety to benefit the international community, investigators need to examine the social condition and cultural factors that influence the expression and treatment of anxiety. Studies examining the efficacy of CBT have been efficacious among majority White populations for decades (Deacon & Abramowitz, 2004). A meta-analysis of 57 effectiveness studies for anxiety disorders found CBT to be effective across
Cognitive Behavioral Therapy for Anxiety Disorders 55
samples. Yet African Americans or Caribbean Americans of African descent made up at least 20% of the sample in only 10.5% of the studies (one in six studies), and Latinos made up at least 20% of the sample in only 3.5% of the studies (two studies; Stewart & Chambless, 2009). A few studies have examined the efficacy of CBT cross-culturally. Pina and colleagues (2003) examined exposure-based CBT for Latino and European American youth with anxiety disorders; both groups responded to the intervention. In case studies, culturally sensitive CBT for anxiety has been effective for individuals who identify as gay, lesbian, or bisexual (Martell et al., 2004) and for two individuals who immigrated from China and Central America (Weiss et al., 2011). The United States is increasingly diverse. People of color make up over 36% of the population, many of whom identify as gay, lesbian, bisexual, or transgender. One in five Americans experience a physical disability or impairment (Taylor, 2018). Graham and colleagues (2013) called for enhancing the cultural sensitivity of CBT for anxiety in diverse populations and provided specific suggestions to increase cultural competence. At the core of CBT is the ability to connect with our patients, to respect the diversity of culture and life experiences, and to practice with cultural competence.

3 Obsessive-Compulsive Disorder Christine Purdon
O
bsessive-compulsive disorder (OCD) is characterized by the occurrence of obsessions and/or compulsions. Obsessions are intractable, persistent thoughts, images, impulses, or doubt, and compulsions are overt or mental behaviors conducted to prevent or ameliorate distress or a dreaded event or outcome, and/or are performed according to rigid rules (American Psychiatric Association, 2013). Although the lifetime prevalence of OCD is relatively low, with estimates ranging between 1.1% and 3.3% (e.g., Ruscio et al., 2010), it is one of the top 10 leading causes of disability in the world (World Health Organization, 1999) due to its costs in time and energy. In their epidemiological study (N = 2073), Ruscio et al. (2010) found that obsessions consume an average of 5.9 hours per day and compulsions 4.6 hours per day. The degree of impairment caused by OCD is on par with schizophrenia (Moritz, 2008). Furthermore, Ruscio et al. found that 28% of their sample had subthreshold symptoms of OCD, suggesting that it has an even greater public health burden than is suggested by merely the prevalence of clinically significant symptoms. In the absence of treatment, the course of OCD is chronic. In a 2-year prospective study, the probability of full remission was 6% (Eisen et al., 2010). Although exposure-based treatment has an efficacy rate of 80% to 95%, treatment dropout rate is an estimated 19%, which reduces efficacy to as low as 60%, and this does not include treatment refusal rates, for which we have very little data (Ong et al., 2016). OCD is associated with significant impairment, it is unlikely to remit in the absence of treatment, and treatment does not benefit almost half of those https://doi.org/10.1037/0000219-003 Handbook of Cognitive Behavioral Therapy: Vol. 2.

seeking it. This presents a moral imperative to better understand its development and persistence, and better help people engage with and benefit from effective treatment. This chapter reviews the characteristics of obsessions and compulsions, describes cognitive behavioral theories of OCD, provides an overview of the main treatment approaches, and offers suggestions for formulating the problem in OCD, framing treatment, and collaboratively executing it.
SYMPTOMS Obsessions Obsessions are repetitive, unwanted thoughts that the individual seeks to control. Although OCD is rare, obsessive thoughts are a universal experience (e.g., Purdon & Clark, 1993; Rachman & deSilva, 1978). Content areas of obsessions include contamination fears; repugnant obsessions involving themes of sex, aggression, or blasphemy; obsessions involving passive harm (e.g., forgetting to turn off an appliance and causing a fire); obsessions involving symmetry/exactness obsessions (with or without superstitious ideation); and nonsensical obsessions (e.g., snippets of songs, number sequences, an urge to count). Obsessions can occur in the form of verbal propositions (e.g., “Chemicals cause cancer”), images (e.g., an image of one’s house on fire), impulses (e.g., a sudden, unwanted impulse to swerve into the next lane while driving), and doubt, which is characterized by “what if . . .,, “did I . . .,” “maybe I . . .,” and “should I . . .” Although doubt is often considered a subtype of obsessive thought, it is important to keep in mind that, historically, OCD has been referred to as the “doubting disease,” which speaks for the centrality of doubt in symptom presentation regardless of the content of obsessions. Clinically, it is helpful to recognize doubt as a form of obsession that can reflect any of the content areas (e.g., “Maybe I am a pedophile.”; “What if this sunscreen interacts with my hand lotion to create a carcinogen?”; “Did I run over someone back there and not notice it?”; “Maybe these aren’t, in fact, perfectly aligned.”; “Maybe that red stain was blood.”; “What if I am not really in love with my husband?”). Compulsions According to the DSM-5, compulsions are actions performed to ameliorate the distress associated with the obsessions and/or to prevent some feared outcome, and/or are behaviors that are performed according to rigid rules. Types of overt compulsions include washing, checking, repeating, ordering/arranging, counting, superstitious rituals (e.g., ensuring one walks in a clockwise direction), and overt reassurance seeking. Reassurance seeking is essentially checking by proxy, and it can be overt (e.g., asking a spouse whether they love them, asking a spouse if the spouse is sure they saw someone lock the door, scouring the internet for reassuring information such as how long bacteria can live on a countertop) or quite subtle (e.g., asking indirect questions to obtain reassurance, such as questions about the person’s health). Covert compulsions include
Obsessive-Compulsive Disorder 69
invoking mental images or phrases, mentally reciting prayers or “safe” phrases, mental checking (e.g., for indications of sexual arousal, for the memory of having locked the door properly), and mental reassurance seeking (e.g., reviewing all the characteristics one does not have in common with a pedophile, reviewing the research one has done about germs, closely observing loved ones for indications of good health). Like obsessions, compulsions are almost universal behaviors, but they are performed in a prolonged and/or inflexible manner until their goal is met or other demands supersede them. It is also important to note that compulsions are typically infused with doubt as to whether the goal has been met, whether it is okay to move on, whether it has been done “properly,” and whether one’s memory and sensory experiences can be relied upon to establish the above to the degree of certainty required.
HISTORY The symptoms of OCD have been recognized for centuries, and historical records about many public figures appear to suggest that they may have had OCD. For example, John Bunyan was said to be overwhelmed with obsessive thoughts regarding sin and the devil. Martin Luther was plagued with fears he would blaspheme when praying. Charles Darwin had persistent, repugnant images. Obsessive-compulsive symptoms are mentioned in ancient early texts on mental illness. In 1903, Janet provided a detailed phenomenological description of OCD and the characteristics of its sufferers. Freud considered OCD a neurosis and driven by unconscious conflict between the id and ego, which generate obsessions that symbolically represent the id instinct rejected by the ego, but which represent a threat that the unacceptable id instinct is surfacing. Compulsions are performed to neutralize the obsession and keep the feared instinct repressed. Behavioral theory holds that obsessions elicit an aversive affective reaction, which the compulsion alleviates. This reduction in distress serves as negative reinforcement for the compulsive act. Furthermore, the performance of the compulsion terminates exposure to the obsession, which prevents extinction of the emotional response. Researchers such as Rachman (1971, 1976, 1997, 1998) and Salkovskis (1985, 1989) observed that an obsessive thought in and of itself is only a source of distress to the extent that it is appraised as a threat, which was the catalyst for the development of the cognitive behavioral model of OCD described in the next section.
COGNITIVE BEHAVIORAL MODEL OF OCD The cognitive-behavioral therapy (CBT) theory of OCD is the leading psychological model of OCD. Since Rachman and Salkovskis’s seminal work on cognitive
70 Christine Purdon
appraisal in OCD, the model has been elaborated in response to subsequent research, particularly that on appraisal and on self-perpetuating mechanisms in compulsions. According to the model, obsessive thoughts are appraised as signaling threat of some kind, which evokes distress of some kind. People engage in a range of escape and avoidance behaviors to either prevent the obsession from occurring, to reduce the possibility of a feared event occurring, and to reduce the distress. The most salient of these actions are of course compulsions. All such actions interfere with new learning about the obsession and its appraisal, as well as the need to perform the compulsion. Meanwhile, compulsions become prolonged and repetitive due to several self-perpetuating mechanisms, including poor memory and sensory confidence, which can evoke a doubt-repetitiondoubt cycle. In the next sections, each element of the model is reviewed, and then the way the components operate together to create an insidious cycle is examined. Obsessions, Distress, and Appraisal Obsessive thoughts are highly idiosyncratic in nature but fall into several themes, including (a) contamination (e.g., with respect to germs, dirt, chemicals, bodily fluids); (b) repugnant (i.e., those with sexual, religious, aggressive themes that decidedly go against one’s morals and values); (c) symmetry/exactness (need for objects to be aligned or “just so,” for body sensations to be equalized bilaterally); and (d) concerns about whether one has caused, or will cause, harm due to carelessness (e.g., while driving, locking the house, turning off appliances, preparing food). Obsessive thoughts often evoke anxiety, and when developing the case formulation, as well as when executing treatment, it is useful to be mindful of ways in which anxiety affects both mind and body. For example, anxiety narrows the attentional scope such that threat-relevant stimuli are attended to at the expense of other information; it can result in exclusive focus on highly salient but not necessarily constructive goals; and it makes threat-relevant memories more accessible (for reviews, see Mitte, 2008; Richards et al., 2014). Anxiety, of course, activates the sympathetic nervous system, which results in physiological arousal. Although a response to threat detection, the symptoms of physiological arousal can be readily interpreted as a signal that threat is truly present, thereby enhancing negative appraisal of the thought’s meaning. For clients with repugnant sexual obsessions, symptoms of anxious arousal can readily become confused with symptoms of sexual arousal, which is often experienced as strong internal evidence that the obsession is meaningful and important. Although obsessions often evoke anxiety, it is important to recognize that this is not the case for all sufferers. Some people with OCD feel a sense of disgust or a “not just right” feeling without any sense of foreboding or anxiety, apart from anxiety resulting from secondary appraisal that there must be something wrong if one is feeling disgusted or “not just right,” or that if the feeling
Obsessive-Compulsive Disorder 71
is not ameliorated, it will interfere with other important goals. Both disgust and not just right experiences respond to exposure with response prevention. However, when establishing the case formulation, it is important not to assume that the client’s obsessive concerns evoke anxiety and instead, to take the time to identify the client’s actual emotions. Beliefs and Appraisal The Obsessive Compulsive Cognitions Working Group (OCCWG; Steketee et al., 2003) proposed six types of appraisal and beliefs as especially important to OCD, including responsibility, importance of thoughts, mental control, overestimation of threat, intolerance of uncertainty, and perfectionism. Responsibility Salkovskis (1985, 1989, 1999; Salkovskis et al., 1995) proposed that obsessions develop when normal thoughts activate overvalued beliefs about one’s responsibility to protect oneself and others from harm. Examples include “Failing to prevent (or failing to try to prevent) harm to self or others is the same as having caused the harm in the first place,” “Responsibility is not attenuated by other factors (e.g., low probability of occurrence),” and “Not neutralizing when an intrusion has occurred is similar or equivalent to seeking or wanting the harm involved in that intrusion to happen” (Salkovskis, 1985, p. 579). These general appraisals lead to situation-specific appraisals of the thought’s occurrence, such as “It would be immoral for me to ignore this thought,” “I must be 100% certain that X will not happen before it is moral to go on to other things,” and “I must stop and deal with this now, before anything else.” Salkovskis (1985, 1989) also made the important observation that people with OCD do not fear harm as much as they fear being responsible for harm. For example, people with checking concerns are typically not bothered when their spouse is in charge of ensuring appliances are off before leaving their house for the day, even though they may estimate that the chance of the spouse overlooking something and a fire occurring as being well above zero. Importance of Thoughts Rachman (1998) introduced the idea of “thought action fusion” to describe the beliefs that (a) having an unacceptable thought increases the likelihood of the negative event represented in the thought coming true and (b) having a morally repugnant thought is the moral equivalent to committing a morally repugnant deed. This overemphasis on the thought’s meaning also manifests in beliefs that “obsessional thoughts indicate something significant about oneself (e.g., that one is terrible, weird, abnormal),” and “negative intrusive thoughts must be important merely because they have occurred” (Thordarson & Shafran, 2002, p. 15). Other examples include “This thought reflects my true evil nature,” “Having this thought means I am a bad person,” “If I think this, I must really want it to happen,” “Thinking this can make the event more likely to
72 Christine Purdon
happen,” “If others knew I thought this, they would think I am an evil person,” and “Having this thought means I am likely to lose control over my mind or my behavior” (Rachman, 1997, p. 793). In one instance, a client with repeated obsessive thoughts about the state of her finances believed that these thoughts would not occur unless there was some truth to them, signaling that she had forgotten an expense or, even if she had not, that the thought was a prophetic warning sign. She also believed that she and her partner possessed personality characteristics, such as self-indulgence, that could result in irresponsible accrual of debt. Mental Control Mental control refers to “over-evaluation of the importance of exerting complete control over intrusive thoughts, images or impulses, and the belief that this is both possible and desirable” (Purdon & Clark, 2002, p. 37). Examples of such beliefs include, “I would be a better person if I gained more control over my thoughts,” “If I exercise enough willpower, I should be able to gain complete control over my mind,” and “Being unable to control unwanted thoughts will make me physically ill.” People with OCD will often appraise the recurrence of a thought as further evidence of their weakness of character and inability to maintain control over important matters. Overestimation of Threat Overestimation of threat refers to the overestimation of the severity and/or the likelihood of the occurrence of negative events (Steketee et al., 1998). Examples of such beliefs, as summarized by Sookman and Pinard (2002, p. 64), include “I believe that the world is a dangerous place,” “Bad things are more likely to happen to me than to other people,” and “When anything goes wrong in my life, it is likely to have terrible effects.” Intolerance of Uncertainty Intolerance of uncertainty is reflected in beliefs such as, “If I am uncertain, there is something wrong with me,” “If I’m not absolutely sure of something, I’m bound to make a mistake,” and “It is essential for me to consider all the possible outcomes of a situation.” These ideas lead people with OCD to seek certainty that the occurrence they fear has not, is not, nor will not occur, and feel the need to do so immediately and at the expense of other tasks. Perfectionism Steketee (1999) defined perfectionism as the “tendency to believe that there is a perfect solution to problems, that doing something without mistakes is possible and desirable and that even minor errors will have serious consequences” (p. 146). Examples of such beliefs as they pertain to OCD include “In order to be a worthwhile person, I must be perfect at everything I do,” “If I fail at something then I am a failure as a person,” “I must keep working at something until it is done exactly right,” “There is only one right way to do things,” and “Even
Obsessive-Compulsive Disorder 73
minor mistakes mean a job is not complete.” It is important to note that people with OCD may not exhibit a general sense of perfectionism, but rather seek to ensure that their obsessive concerns have been perfectly satisfied and/or their compulsions perfectly completed. In the case of non-comorbid OCD, perfectionism may be closely tied to overestimation of threat and intolerance of uncertainty. Core Beliefs, Assumptions, and Appraisal Beck’s cognitive model assumes that psychopathology is characterized by negative schemas about self, world, and/or future. The term schema refers to an operating framework for a category of people, places, and things in which previously encoded information about that category is stored. Schemas allow for rapid processing of situational information, such that we can quickly anticipate what is going to happen next and prepare ourselves to respond. Once a schema is activated, relevant memories, images, thoughts, and emotions accompany it, along with evaluative or summative conclusions, or beliefs, about that category. Schemas about self, world, and future are central, and they are often referred to as “core” beliefs. Core schemas are represented in summative and evaluative core beliefs (e.g., “I am bad,” “The world is dangerous,” “The future is bleak”). Once a schema has developed, information consistent with it tends to be noticed and encoded (e.g., a dirty look from someone for being a few minutes late), whereas information inconsistent with it tends to be ignored, trivialized, or discounted (e.g., others being unconcerned about one’s lateness). Thus, they can readily give rise to information-processing biases. Interestingly, core beliefs regarding self, world, and future have not been well-explicated in the cognitive behavioral model of OCD. Salkovskis (1985, 1989) identified core beliefs of overvalued responsibility, as described previously, as central to the development and persistence of OCD. Rachman (1971, 1997, 1998) observed that the content of obsessive thoughts often reflect the themes of moral systems (e.g., aggression, sex, blasphemy, cleanliness), and thus, obsessive thoughts, which represent a violation of those moral systems, are likely to be experienced, at least initially, as sinful, disgusting, alarming and/ or threatening and will evoke distress. Whereas most people are able to reappraise the thought as silly, senseless, and meaningless, albeit unpleasant, those prone to developing obsessional problems will appraise the thought as having important meaning and relevance for the self. Purdon and Clark (1999) elaborated on this and argued that obsessive thoughts that threaten one’s self-view are more likely to breach the attentional threshold. Most people will assimilate the thought into their self-view (e.g., “Even a person like me can have a thought like this”), but those vulnerable to OCD may alter their self-view to accommodate the thought (e.g., “Maybe I am a homicidal maniac at heart”). Clark and Purdon (1993) also argued that people with OCD may have a fewer number of domains by which they define themselves (e.g., being a moral person, being a caring person, being a responsible
74 Christine Purdon
person). Thus, thoughts that challenge these domains (e.g., the thought that one may have caused harm) compromise self-worth and will activate attempts to repair potential damage and compensate for one’s failings. This is consistent with Guidiano and Liotti (1983), who proposed that compulsive behaviors emerge as a strategy for gaining approval and self-worth. Indeed, it has been found that obsessions that contradict valued aspects of the self are particularly distressing (Rowa et al., 2005), that OCD symptoms are associated with a sense of incompetence in key self domains (Doron et al., 2007), and that people with OCD tend to exhibit ambivalent core beliefs (e.g., “Maybe I am incompetent”; Bhar & Kyrios, 2007). Given that important schemas are formed in childhood, there is emerging research on the association between attachment and OCD as well as family factors. Doron et al. (2011) found that people with OCD had higher attachment anxiety (but not attachment avoidance) in their adult relationships than people with anxiety disorders, even controlling for depression. Rachman (1976) observed that we are more likely to be criticized for actions for which we are responsible than for actions for which we are not responsible. In their classic analysis of obsessions and compulsions, Rachman and Hodgson (1980) argued that critical parenting heightens the perceived consequences of errors, leading to excessive caution when one is responsible for the outcome, as well as the need for certainty that it has been done well. Salkovskis et al. (1999) identified parental criticism as a pathway to inflated responsibility and similarly argued that persistent criticism increases the perceived cost of being responsible. Guidiano and Liotti (1983) and Ehntholt et al. (1999) generally agreed that when people receive contradictory messages about their self-worth (i.e., when subjected to criticism), the compulsion becomes a means of gaining a positive sense of self. Similarly, McFall and Wollersheim (1979) posited that perfectionism may evolve from the need to avoid being criticized. There is empirical evidence for an association between criticism in family of origin and current family, OCD symptoms, and overvalued responsibility, although the literature is small and approaches to studying the issue are quite varied (Pace et al., 2011). In addition to a need to avoid being held responsible for outcomes and therefore criticized, a critical environment may also lead one to mistrust one’s own judgement and perceptions. If people behave in ways that strike them as quite reasonable and justifiable, and yet they find themselves criticized by authoritative people, they may conclude that their own judgement and perceptions are misleading, flawed, or otherwise untrustworthy. Thus, they may have difficulty achieving an internal, felt sense that they have done something properly or that danger has passed (e.g., Lazarov et al., 2010; Szechtman & Woody, 2004). Taken together, it may be the case that people with OCD exhibit ambivalent or negative core beliefs about the self (e.g., “I am flawed,” “Maybe I am a bad person,” “I am careless”) which generate assumptions (e.g. “If I am in charge things are more likely to go wrong,” “I will be held accountable for negative events, even when they are mostly out of my control,” “If there is a possibility
Obsessive-Compulsive Disorder 75
that something I do can cause harm I shouldn’t do it”), and rules for living, such as “When it comes to matters of harm, if I do the action to prevent it perfectly I can’t be faulted,” “I can and must control thoughts lest they lead to harm,” “It is immoral to move onto other things until you know for sure you have prevented harm,” and “If I am alerted to the possibility of harm, no matter how remote, it would be immoral to ignore it.” These beliefs and assumptions evoke negative appraisal of the obsessive concern as a threat, which drives the compulsion. The compulsion is done to ameliorate distress and/or prevent harm, but also to preserve self-worth. Thus, there is an imperative for perfection and perceived need for certainty in completing it. A final observation is that people with OCD do not necessarily exhibit a general intolerance of uncertainty, but rather a high intolerance of uncertainty regarding the obsession and the extent to which the compulsion has been done properly. Ameliorative Strategies People with OCD can engage in a wide range of strategies to ameliorate the distress over the obsession, to avoid or prevent feared events, or to avoid or prevent having to do the compulsion, including thought suppression, avoidance, and of course compulsions. Thought Suppression People with OCD generally attempt to suppress their obsessive thoughts, and in fact, thought suppression is a defining feature of obsessions in the DSM-5. Purdon et al. (2007) had people with OCD keep a diary record of their thought suppression attempts over three days and found that suppression attempts were frequent and effortful. The top reasons reported for suppression were to get rid of the obsession before the compulsion became necessary, to prevent anxiety from escalating, and to prevent potential harm. It is generally accepted as psychological fact that suppression results in a resurgence of unwanted thoughts (the so-called “white bear effect), but in reality there is very little evidence that suppression results in an escalation of the frequency of obsessions (for reviews, see Abramowitz et al., 2001; Magee et al., 2012; Purdon, 2004; Rassin et al., 2000). Purdon et al. (2007) found that suppression actually facilitated functioning about a third to half the time; that is, it was effective in managing mood and improving concentration. However, suppression is seldom 100% effective, and there is research suggesting that thought recurrences can reinforce negative appraisal of the thought’s meaning and importance (e.g., “The more I have this thought, the more concerned I become about my personality”; Magee & Teachman, 2007; Purdon et al., 2005, 2011). Invoking the “white bear effect” to explain the persistence is thus not advised, both because the evidence does not bear it out and because it may be quite inconsistent with people’s own experiences of periodic successful thought control. However, when developing the case formulation, it is important to factor in the client’s expectations for thought control and their interpretation of thought recurrences.
76 Christine Purdon
Avoidance People with OCD use a wide range of avoidance strategies to preempt occurrences of the obsession, to prevent harm, and to reduce distress when contact with feared stimuli is unavoidable. Newth and Rachman (2001) observed that people with repugnant obsessions also tend to avoid revealing the content of their obsessions in order to avoid causing the obsession to be acted upon or otherwise come true, out of shame and embarrassment and out of fear of practical consequences (e.g., having their child removed from their custody). One means of avoidance is thought suppression, as previously discussed. In order to avoid experiencing the obsession, people may also avoid places where the obsession is likely to be triggered (e.g., hospitals, playgrounds, public bathrooms, cemeteries), objects (e.g., knives), situations (e.g., being the last one to leave the house, being the one to tend to a wound, being alone with a child, driving, changing a diaper), and people (e.g., people who have or may have an illness, children). The avoidance can be quite subtle as, for example, when one client realized that of the two family cars, he had been avoiding driving the red one because the color red triggered his obsessive concerns about blood. When people with OCD are unable to avoid contact with feared events, situations, objects, or people, subtle avoidance strategies may be used, such as avoiding direct contact with the stimulus (e.g., wearing gloves, using the sleeve to open a door, maintaining distance) or enjoining others to perform tasks within the situation (e.g., changing a diaper). Rachman (1998) observed that as the idea that the thought portends danger persists, the number of external cues that become relevant to the thought increases (e.g., someone with the obsession of stabbing a loved one with a knife may start to view any sharp object as a potential weapon and begin avoiding it). Thus, the range of threats in the individual’s environment increases, which means that the number of triggers for the obsession increases. Avoidance strategies are understandable, but they work against people in the long term. Avoidance prevents new learning about the feared stimulus and helps sustain negative appraisal of the obsession and appraisal of the perceived need to do the compulsion. Avoidance is also time consuming and inconvenient, contributing to the intrusiveness of the disorder. Hypervigilance People with OCD are hypervigilant for triggers for the obsessive concern, for information that harm has or will occur, as well as for indications that the compulsion may not have been successful in averting harm. People can be vigilant for internal information (i.e., body sensations, thoughts) in addition to external information. Ironically, avoidance of triggers requires hypervigilance for those triggers, so avoidance may be preceded by threat monitoring. People with contamination concerns will often track a “contaminated” object (e.g., a handbag that was set down on the floor) and monitor all the places that object has touched so those spots can be avoided or cleaned, or they may constantly monitor the ground or other areas for contaminants in order to avoid contact (e.g., blood, feces, band-aids, chemicals).
Obsessive-Compulsive Disorder 77
People with symmetry/exactness concerns may track the movements of people in their home so they can follow behind and correct misplaced objects. People with repugnant obsessions may monitor their body sensations for indications of inappropriate sexual arousal, monitor the news for indications that an accident has occurred, or closely monitor their thoughts for indications of a recurrence of the obsession. People with obsessions about illness or contamination may monitor their bodies for symptoms of illness. Avoidance and vigilance monitoring tend not to be included on measures of OCD symptoms, but they are important markers of the intrusiveness and severity of the disorder and the extent to which treatment has succeeded. Like avoidance, hypervigilance is understandable, but it is unhelpful in the long term because it ensures that even the smallest indication of threat are attended to, and this may occur at the expense of important information, such as information about the safety of the situation. Attending to bodily sensations can cause people to notice and react to perfectly normal physiological changes and to misattribute their cause. Monitoring to determine whether harm has occurred is problematic because the null hypothesis (i.e., that harm has not occurred) cannot be proved; the failure to detect indications of harm could simply mean that harm has not been discovered yet. Finally, as discussed in more detail in the next section, repeating an action, such as monitoring one’s body, undermines confidence in one’s sensory experiences. Compulsions Compulsions are overt or covert (i.e., mental) actions that neutralize obsessive concerns and/or ameliorate distress and tend to be conducted in a rigid or ritualized manner. There is a growing body of work suggesting that once a compulsion is performed, several self-perpetuating mechanisms follow. First, a number of studies have found that individuals with OCD have less confidence in their memory, cognitive, and sensory faculties overall than do individuals with another psychiatric diagnosis or individuals with no diagnosis (Hermans et al., 2003; Nedeljkovic & Kyrios, 2007; Nedeljkovic et al., 2009; van den Hout et al., 2008), particularly when referencing OCD-relevant actions such as locking a door (Hermans et al., 2003). People with OCD are then especially prone to doubting whether they have done something correctly and, therefore, are inclined to repeat it just to be sure. Meanwhile, repeating an act compromises memory, sensory, and cognitive confidence in as few as five repetitions, even though actual memory is intact (Coles et al., 2006; Fowle & Boschen, 2011; Radomsky et al., 2006; van den Hout & Kindt, 2003). This effect is especially pronounced under conditions of high responsibility and on tasks relevant to current goals (Boschen & Vuksanovic, 2007; Radomsky et al., 2014). Furthermore, as an act is repeated, the amount of detail that the individual seeks to track in order to form a strong memory later increases, thereby taxing working memory, which makes it difficult to achieve a memory for the action with the clarity desired. Thus, once an action is repeated, confidence that the compulsion has been done properly is
78 Christine Purdon
undermined, and this in turn can readily lead to generalizations about one’s memory, cognitive, and sensory acuity. However, it is important to note that compulsions are handily terminated a great deal of the time. In their study of compulsions conducted in vivo, Bucarelli and Purdon (2015) and Bouvard et al. (2020) found that compulsions yielded a sense of satisfaction and/or a sense that enough had been done to prevent harm more often than not, even when they had been repeated. This intermittent reinforcement schedule is one of the most difficult to break. Furthermore, this bespeaks the fact that compulsions often work for people. When the obsessive concern (and concomitant distress) arise, the compulsion can be a very efficient means of handling it. On the other hand, almost half the time the compulsion does not achieve its goal, which is useful for therapists to note when discussing beliefs about the utility of the compulsion. Although compulsions can “work” in the short term, they prevent new learning about the meaning and importance of the obsessive concern. When the feared event does not occur, it is attributed to the performance of the compulsion. When the compulsion does not meet its goals, sufferers believe that their distress is at least lower than it would have been had the compulsion not been done. The reduction in distress afforded by the compulsion is negative reinforcement for its continued use. Furthermore, the performance of the compulsion terminates exposure to the distress associated with the obsession, which prevents new learning about the obsession and compromises extinction of the emotional response, which would decline on its own without the compulsion. Finally, as noted, the insidious cycle of repetition-doubt-repetition prolongs the compulsion in the moment and undermines general confidence in memory, cognitive, and sensory systems.
CASE FORMULATION The route to successful treatment is the development of a case formulation that identifies the “culprits” in the persistence of the client’s obsessions and compulsions, which the client understands and shares. This allows the client and therapist to ally with each other against the OCD. A good assessment results in a solid understanding of the breadth, range, and severity of symptoms, the beliefs, assumptions, and appraisal of both obsessions and compulsions, and the avoidance, vigilance, and safety strategies used, as well as relevant factors in the client’s life, such as learning history (e.g., parental criticism, fear conditioning). The therapist can also bring to bear research on thoughts and thought suppression; the association between repetition, doubt, and memory/cognitive/sensory confidence; attentional processes (i.e., that anxiety focuses attention on threat-relevant stimuli at the expense of other information); and relevant learning principles such as the role of distress reduction in reinforcing the ameliorative strategies. It is also important to understand the activities that the OCD compromises, so as to introduce positive goals for the individual to strive
Obsessive-Compulsive Disorder 79
toward, instead of focusing treatment solely on symptom reduction. Once the therapist and client have a solid working formulation that explains (not just describes!) the persistence of the symptoms, the treatment plan emerges into focus. The formulation will develop over time as the client and therapist discover more about these elements and the way in which they work together, but treatment should start with a good working model that clearly identifies the culprits that cause OCD symptoms to persist. As discussed earlier, people with OCD may not be comfortable reporting on the content of their obsessions and/or the extent and nature of their rituals. It is important that the therapist and client have an open discussion about the content of the obsession because otherwise it is difficult to build a case formulation and execute effective cognitive restructuring around the appraisal of the thought’s meaning. If the person has repugnant obsessions, they may find it difficult to disclose content, as mentioned previously. In such cases, it is useful to normalize the content by explaining that many people experience repugnant thoughts and show the client lists of thoughts experienced by people without OCD (e.g., Purdon & Clark, 1993; Rachman & deSilva, 1978). As a first step, the therapist can also ask the client to write the content down and then read it aloud. People with OCD may lack perspective on the extent to which their habits are excessive. For example, they may not know how long most people spend in the shower or how often most people clean their bathrooms and kitchens and, therefore, are simply not aware that their habits are quite different. Some good preliminary or supplementary questions to ask include “Do you tend to use a lot of hot water and/or soap in the shower?” “Does cleaning take you a lot longer than it does other people you know?” “Do the people you live with often tell you that you spend too much time in the shower/cleaning/ordering/ etc.?” “Do you tend to go through a lot of soap and/or hand sanitizer in a week?” “Does it take you a long time to leave the house?” “Does it take you a long time to check everything before going to bed or leaving the house?” “Do you prefer it if others lock up the house rather than you?” “Are there people, places, or situations that you prefer to avoid, or endure with distress if you can’t avoid?” “Do you have thoughts that you have to ‘undo,’ suppress, or ‘correct’?” and “Do you find it hard to stop doing certain actions until you are absolutely certain you have done them well, even it if means being late for other things or keeping people waiting?” To establish diagnosis, structured interviews are the gold standard. However, if there is limited time available and only a quick OCD screen can be conducted, options are available. NICE (2005) guidelines recommend the Zohar-Fineberg Obsessive Compulsive Screen (Z-FOCS), which consists of five questions, has good psychometric properties, and can be administered in 1 minute (Fineberg et al., 2008). The most widely used diagnostic interviews are the Structured Clinical Interview for DSM-5 (SCID-5; First et al., 2015) and the Mini Neuropsychiatric Interview for DSM-5 (MINI 7.0; Sheehan, 2016). The MINI takes considerably less time than the SCID and has excellent reliability. If time is
80 Christine Purdon
limited, the OCD modules from either can be used on their own to establish diagnostic status. There are numerous symptom severity measures, of which Grabill et al. (2008) provide an excellent comprehensive review. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS; Goodman et al., 1989a, 1989b) is commonly used because it readily identifies the range of symptoms, target symptoms, and level of insight; has well-established norms; and is sensitive to pre- and post-treatment symptom changes. The self-report version of the measure has shown good consistency with the interviewer-administered version (Federici et al., 2010). Given the degree of comorbidity with depression and the potential of depression to compromise motivation, it is advised that depressive symptoms be assessed. The Beck Depression Inventory-II (BDI-II; Beck et al., 1996) is an obvious choice. In order to assess beliefs about obsessive thoughts and their appraisal, the OCCWG developed, respectively, the Obsessive Beliefs Questionnaire (OBQ; OCCWG, 2001; Steketee et al., 2005) and the Interpretation of Intrusions Inventory (III; OCCWG, 1997). These measures can be used to identify targets for CBT and to assess treatment progress. It is important to note that some people with OCD score low on these measures, and some have argued that they represent a subtype of OCD not characterized by negative appraisal (e.g., Taylor et al., 2006). However, it may also be the case that only one or two negative beliefs about and/or appraisal of obsessive thoughts, held strongly, are necessary to evoke clinically significant distress. It is important to use scores on any self-report measures as a guide to further discussion, as opposed to ends in themselves. Once diagnosis and severity have been assessed, the therapist and client begin working on a formulation of the problem. Kuyken et al. (2009) observed that a sound formulation explicates the internal logic of the obsessive-compulsive cycle, is derived collaboratively, creates a simple (but not simplistic) model to explain a complex experience, and helps clients develop a more compassionate understanding of their symptoms and of themselves. Most importantly, the case formulation explicates the mechanisms by which the problem persists, as opposed to simply describing the symptom cycle. In OCD, the formulation must explain what is meaningful about the obsessive concern (i.e., why it captures and holds attention in the first place), why it evokes the aversive emotional response/distress, and why the compulsions are repeated both within and across episodes. To accomplish this, it is useful to have the client keep a diary record of their obsessions and compulsions for a week. Drawing from a nomothetic model of OCD, the client is asked to record the content and form of the obsessive thought (i.e., thought, image, impulse, doubt); the personal meaning and importance of the obsession; the range of emotions it evoked; and the coping strategies used to manage that distress, with particular focus on the compulsions. The client also reports on how often they repeat the compulsions within the episode and how successful the compulsions were in achieving their goal. The client also
Obsessive-Compulsive Disorder 81
reports on the impact of repetition on memory, cognitive, and sensory confidence. Using these data as a guide, the therapist and client conduct a detailed cognitive-behavioral assessment of their OCD with the goal of developing a strong working case formulation. The case formulation identifies the obsessive preoccupation, the appraisal of the obsessive thought, the subsequent emotions, and the ameliorative strategies used and their emotional, behavioral, and practical consequences, and the beliefs and assumptions generating the appraisal.
DESCRIPTION OF MAIN TREATMENT APPROACHES AND THEIR PROCEDURES According to United Kingdom’s National Institute for Health and Care Excellence (NICE; 2005) and the American Psychiatric Association (2007) guidelines, the psychological treatment of choice for OCD is cognitive therapy (CT), which includes exposure with response prevention (ERP). ERP refers to exposure to the obsession while the compulsive ritual is prohibited. In CT+ERP, negative appraisal of the thought’s meaning is addressed via standard cognitive restructuring techniques and behavioral experiments, while the aversive emotional response to the obsession is extinguished through ERP. The NICE guidelines recommend a stepped approach, such that milder cases receive a brief (i.e., 10 therapy hours or less course) of CT+ERP with structured self-help materials or telephone contact with a therapist, or they receive group treatment. For people who fail to benefit from such low intensity approaches and for those with more severe symptoms, a choice of either a more intensive course (i.e., 10+ therapist hours) of CT+ERP or a course of selective serotonin reuptake inhibitors (SSRIs) is recommended. When symptoms are so severe that the person is unable to leave the house, telephone sessions are recommended. Family members are almost invariably involved in the client’s compulsive rituals by providing reassurance or assisting in or conducting safety, checking, cleaning, and avoidance rituals. Family dynamics may also play a role in treatment outcome. For example, when the sufferer’s family environment is characterized by over-involvement, hostility, and high criticism, treatment outcome tends to be poorer (for a review, see Purdon, 2012). Furthermore, although family members may genuinely wish for the client’s suffering to be relieved, they may find adjusting to changes in the client’s behavior and perspective difficult and may unintentionally behave in ways that undermine treatment. For example, they may find it difficult to give up providing reassurance or protecting the family member from responsibility. If possible, it may be useful to meet with key family members to help them develop a compassionate understanding of the client’s symptoms and the way treatment will help overcome them, and to instill hope. Once treatment is underway, family members need to have a clear understanding of how best to respond to reassurance, avoidance, and other behaviors
82 Christine Purdon
that maintain the client’s OCD. Family members should be discouraged from being complicit in rituals but without taking a mocking, critical, or harsh tone, which tends to exacerbate rituals (Amir et al., 2000). Family members can, instead, be encouraged to be firm but supportive (e.g., “You are asking me for reassurance, and we have agreed that it doesn’t help you overcome your OCD for me to provide it. I know you are strong, you are doing great, and you can ride through the anxiety. I have confidence in you”). Family members can also be given basic instruction in ERP and can coach clients in between sessions. Van Noppen and Steketee (2003) and Renshaw et al. (2005) have advocated for a multifamily behavioral treatment in which family members are trained in exposure to rituals, contracts to improve communication within the family, and reducing hostile and antagonistic responses to OCD. Guidelines for this approach are outlined in these respective papers. Setting the Stage for Treatment The first phase of treatment involves identifying the specific targets of treatment, or the culprits, presenting the treatment plan, and setting the stage for treatment. CBT of OCD requires people to refrain from the strategies that they have used to cope with distress, which they believe serve to prevent harm, and which, in turn, reflect highly important goals and values. Unless the rationale for this is obvious and compelling, they are vulnerable to refusing treatment, dropping out, or continuing with treatment while avoiding its anxiety-evoking elements (e.g., Maltby & Tolin, 2003; Vogel et al., 2004). Avoidance strategies and compulsions advance valued goals (e.g., to protect the family from harm, to prevent sin, to be a good parent), and many clients may fear that treatment will require that they work against these goals. Once the formulation has been developed, it can be useful to identify the valued aspects of self or important goals that are being advanced by the compulsions (e.g., expressing caring via elaborate checking rituals to ensure safety) and those that are being compromised by the compulsions (e.g., conscientious punctuality that is compromised by habitual lateness due to checking routines). The former can be understood as an important reason that the compulsions developed and persist, whereas the latter is the reason the client has sought treatment. The overall goal of treatment is to help the client advance the former without compromising the latter. Once the therapist and client are in agreement as to what the culprits are and how they compromise valued goals, it is important to discuss that treatment involves taking risks. These risks include not engaging the OCD “voice” and thereby risking ignoring a genuine threat, terminating ameliorative strategies before achieving a sense of certainty, and tolerating the ensuing doubt (thereby risking that harm may have, or could in future, occur). The goal of treatment is to help people learn to take the same acceptable risks that people without OCD take and that they themselves take on matters outside obsessive concerns. Furthermore, people with OCD tend to overestimate risk, particu-
Obsessive-Compulsive Disorder 83
larly when they are the ones responsible for the outcome, and they feel a moral imperative to prevent that harm, no matter how small its probability. In setting the stage for exposure and behavioral experiments, it can be useful to develop a reasonable estimation of threat, not for the purposes of reassurance, but rather to establish that the obsessive concern typically has a very remote risk of occurring. Consider Ms. K., who was preoccupied with concerns that she may have a bank overdraft and checked her account balance, credit card statements, and her wife’s spending multiple times per day. The therapist and Ms. K. sought to estimate the probability that at that moment in time her expenses outweighed their income. Ms. K. reasoned that for this to happen, (a) her wife would have had to have spent more than $300 in the past week, (b) Ms. K. would have had to have miscalculated their income, and (c) there would have had to be expenses of which she was unaware. Ms. K’s estimations of each event were, respectively 0.08, 0.10, and 0.05. Thus, even with a 10% chance that Ms. K. had miscalculated their income, the probability of her feared event happening was 0.08 × 0.10 × 0.05 = 0.0004; the chance that the event would not happen was 99.996%. Yet the probability that Ms. K. was compromising important goals in the service of assuring herself that an event of minute probability had not occurred was 100%. The therapist can then discuss the probability that Ms. K. could have gotten into a bad car accident on her way to the office, which she estimated to be about 2% but said it was negligible compared with the inconvenience of not driving. This could be discussed as an example of how Ms. K. takes fully acceptable, normal risks on a daily basis; Ms. K. felt no moral imperative to stop driving even though it carried considerably more risk than having an overdraft. Thus, there may not be a moral imperative to act on the obsessional thought any more than there is to act on the thought that there is a 2% chance of getting into a car accident. Having established this, the client and therapist can examine the values and goals that are being supported by the compulsion and those that are thwarted by the compulsion. Consistent with Egan et al. (2014), the therapist can draw a graph with a horizontal line that reflects the goals and values supported by the compulsion, as well as an intersecting vertical line that reflects the goals and values compromised by the compulsion. Each line has anchors of 0, which means “not succeeding in meeting these goals at all,” and 100, which is labelled “fully meeting these goals.” The client rates themselves on each line and plots the point of intersection. This exercise often helps clients realize that no matter how much effort they put into compulsions, they are unable to achieve the goals the compulsions support, as they are oriented almost exclusively to how they fall short while typically having perfectionistic standards for goal attainment. Therefore, the point of intersection is typically in the lower two quadrants, and often in the lower left quadrant. Treatment aims to help the individual move into the upper right quadrant. The benefit of illustrating this point is that it helps people be assured that in order to overcome OCD, they do not have to give up the very values and goals that define them (e.g., they do not have to
84 Christine Purdon
compromise their religious traditions, they do not have to care less about their families). A second benefit is that it addresses what is often the white elephant in the therapy room, which is that compulsions both work and are expressions of important goals and values, as opposed to purely shameful behaviors that must be annihilated at all cost. Active Treatment The ultimate goal of active treatment is to help the client develop a defiant and airtight stance against the OCD. For Ms. K. it would be, “Yes, OCD, you might be right, I might be running further into debt, but probably not, so I am going to accept that risk and just get on with the immediate and important things I know need my attention right now rather than checking my bank balance.” Exposure With Response Prevention Pyschoeducation about the self-perpetuating mechanisms of compulsions is an essential prelude to conducting exposure. This will have been part of the case formulation but should be a continued focus of discussion, and in helping the person recognize that repetition is a major culprit in OCD, persistence can assist with motivation for ERP. In ERP, the obsession is evoked, and the person is prohibited from conducting the compulsion. Once the distress declines substantially, the process is repeated until the obsession causes little to no distress. ERP can appear deceptively simple, and in the absence of a strong working case formulation, therapists can make the mistake of simply having people expose themselves to any stimuli that make them uncomfortable. However, this can miss the point entirely. Consider the obsessive concern “Maybe I’m gay and am ruining my partner’s future by staying with her.” In order to avoid triggering the obsession, people with this concern may avoid naked images of same sex people, just as the person phobic of dogs might dislike and avoid a dog park. In both cases, the target of exposure should be the primary fear, not a secondary fear of a stimulus that evokes the primary fear. The primary fear for our OCD clients was that the thought “Maybe I’m gay” signaled something important and meaningful about their sexual orientation, which in turn meant that their heterosexual relationship was fraudulent. Exposure should target the doubt about being gay while prohibiting attempts to achieve certainty that they are not gay. If required, stimuli can be used to evoke the obsession (e.g., pictures of same sex people), but extinction is of the response to the obsessive doubt, not the pictures, just as when working with someone who is afraid of dogs, extinction is to the fear of dogs, not dog parks. The case formulation is of central importance in determining what to expose the client to and in what order. The therapist must first ask, “What does the client need to achieve new learning about?” Ms. K. would benefit from new learning as to (a) whether having the thought that her bank balance might be low truly signals imminent and clear danger and requires immediate action, (b) whether she has a moral imperative to drop everything to prevent that
Obsessive-Compulsive Disorder 85
danger, and finally, (c) whether or not her distress would truly fail to dissipate unless she did her compulsions. The next question in ERP is where to start. Therapists often have clients develop an exposure hierarchy starting with stimuli and situations that cause moderate distress and lead up to those most feared. One downside of this approach is that, at least initially, the prospect of having to face the dreaded situation at the top of the hierarchy can reduce motivation to progress (e.g., “If I do step four this week I’ll have to do that last step in just a couple of weeks!”). It can also lead to defining treatment goals in terms of progress on the hierarchy as opposed to reclaiming one’s life. It can be more useful to build exposure around the client’s treatment goals (e.g., to get to work on time), identify the compulsions that get in the way of those goals, and identify the factors that influence distress when the client’s obsessions occur (e.g., proximity, presence vs. absence of other people, home vs. other places). The therapist and client can then identify a starting point (e.g., exposure to thoughts about one’s bank balance when at home and after having checked once that day) and build on that each week, with flexibility for the client to move ahead between sessions as long as they are clear on the goals and purpose of the exposure. Furthermore, safety behaviors can be built into exposure. In traditional approaches to ERP, all safety behaviors are prohibited (Foa & Kozak, 1986), which can make exposure very difficult to accept. There is now fairly clear evidence that judicious use of safety behaviors does not impair extinction and may in fact reduce treatment fears (e.g., Milosevic & Radomsky, 2013a, 2013b). Safety behaviors can be worked into an exposure hierarchy or template (e.g., touch the floor with thick gloves, then thin gloves, then a tissue, then the bare hand). The target of exposure is typically uncertainty as to whether an undesired event has happened, is happening, or will happen or an intrusive feeling (e.g., disgust, not just right) that the person believes needs to be resolved before moving on to other activities. In traditional exposure models, the compulsion is prohibited, but there may be merit in having the client complete the compulsion but stop before they get the sense that it has been done properly, inhibiting further compulsive behavior. This will help the client achieve new learning about both the obsession and the necessity of the compulsion, as well as build tolerance for uncertainty around whether or not the compulsion has achieved its goal. For example, clients with contamination fears can be enjoined to contaminate their hands, wash their hands once (according to recognized hygiene guidelines), and then sit with doubt and uncertainty as to whether their hands are still contaminated while further washing is prohibited. The next step might be to then repeat the previous steps, but then to touch the face with their hands despite not being sure whether their hands are clean. Eventually exposure can involve no washing at all. The therapist is well-advised to conduct exposure in session so the client knows what to do between sessions and heads into the more difficult work in between sessions with mastery experience and a solid understanding of how to execute exposure. In session, the therapist serves as a coach and facilitator.

First, it is useful to revisit the values and goals graph to help the client recognize what goals will be advanced by overcoming the compulsions and, realistically, how much failing to do the compulsion will compromise the goals served by the compulsions. Prior to beginning exposure, the client and therapist review the terms of exposure, which are that the therapist and client collaboratively specify the exercise, that the therapist neither forces the client to do anything nor springs any surprises, and that the client refrains from compensating for the exposure later (e.g., by doing extra rituals once home). Open communication and collaboration will be facilitated by clarity about how exposure will target key culprits. Furthermore, the client and therapist can discuss the many ways the client is advancing the goals served by the compulsion, but in other ways, as well as whether reducing compulsions moves them significantly lower on the goals and values plot. When commencing exposure, the therapist models the desired behavior first. This makes the exercise clear, models a non anxious response to the behavior, and enhances the alliance. During exposure, the therapist is warm and supportive, using statements such as, “You’re doing a really good job” and “If you can hang in a bit longer this is going to pay off even more.” The therapist asks the client to report on their distress level using whatever scale works best for the client. The therapist watches the client’s body language to gauge when distress is increasing or decreasing and ask for ratings accordingly. ERP can also provide a rich environment in which to identify the key cognitive culprit appraisals in action, so when distress increases, the therapist can ask what thoughts were going through the client’s head. Once the situation or stimulus results in significantly less distress, the challenge can be increased. When the exercise is over, the therapist and client evaluate the initial predictions in light of what actually happened and discuss what that means about the appraisal of the obsession and the perceived need to do the compulsion. Finally, the therapist and client plan between-session exposure sessions. One common mistake in ERP (or CBT in general) is that the between-session work is prescribed by the therapist in the last few minutes of the session. Treatment is far better served when the therapist reserves ample time to develop between-session exercises collaboratively with the client, with clear identification of what idea is being tested and the opportunity to discuss practical considerations. With respect to pacing and timing, research shows that massed exposure is more effective than spaced (10 times per week is much more effective than 10 times in 10 weeks; Antony & Swinson, 2000). The client will thus want to conduct at least one exposure per day. The therapist and client will also want to plan how to increase the challenge throughout the week if required. When the client returns for the next session, it is imperative that the first part of the session process the between-session work. What was done and what was learned from it? The session then builds on that new learning. If family members are involved in the compulsions that have been targeted in ERP, it is useful to have them join the client for a session. The goal is to help family members better understand why the compulsions persist and the role of
Obsessive-Compulsive Disorder 87
ERP in treating them. The therapist and family members can discuss how best to support the client through ERP. A key reason why family members participate in rituals is that they find it difficult to see their loved ones suffer. It can be helpful to provide psychoeducation about extinction and frame ERP as “short-term pain for long-term gain.” Cognitive Restructuring Salkovskis (1999) stated that the goal of cognitive restructuring is for the “patient and therapist to work together to construct and test a new, less threatening explanation of the patient’s experience, and then to explicitly examine the validity of the contrasting accounts.” As in ERP, the therapist must be mindful of what exactly to target in cognitive restructuring. The most important rule is that the content of the obsession, and the probability of the feared event, are not the targets for cognitive restructuring. Rather, the appraisal of the obsession that gives rise to the distress, the perceived need to take immediate action, and the intolerance of uncertainty as to whether harm has been averted by the compulsion are. For example, Mr. L. was a 30-year-old man who had had a severe and intractable bladder infection for over a year that significantly affected his life in all domains, and he developed contamination fears around contracting another infection. A previous therapist had asked him what would be the worst outcome of an infection, to which he replied that it would be the need for a colostomy. The therapist proceeded to target his fear of having to get a colostomy, deeming it as dysfunctional (e.g., “What is so bad about that?”). The client dropped out of treatment. The culprit in OCD is not fear of something terrible happening to oneself or a loved one, but rather the ideas that the thought is the vector through which harm will occur, that immediate action is required no matter how minute the probability of harm, and that it is morally or otherwise imperative to perform the compulsion and achieve certainty. In the case of Mr. L., the culprits were the ambivalent core belief that he may be a weak and ineffectual person, appraisals such as “as long as the risk of contracting infection is not zero I must guard against it,” and intolerance of uncertainty with respect to whether his cleanliness rituals had protected him from infection. With appropriately targeted cognitive restructuring, Mr. L. improved dramatically. As in cognitive interventions for any other type of problem, the crux of change is in the client’s ability to generate alternative ways of viewing a problem or thinking about a situation. The therapist’s role is to facilitate insight through guided discovery, not to provide alternative and more constructive ways of viewing anxiety-provoking stimuli and situations. If the therapist provides alternative and more optimistic ways of viewing a problem or thinking about situations, clients could have reactions such as, “She’s my therapist, she has to say that” and “But he doesn’t know all the bad stuff about me!” Although it may take considerably longer for the client to produce alternative explanations and balanced alternatives to OCD-related thoughts, therapy will ultimately be more efficient.

Cognitive restructuring techniques include the downward arrow technique (i.e., asking successive questions through which the core personal meaning or importance of an event is revealed), Socratic dialogue (i.e., dialogue in which hypotheses about a situation, person, or thing are examined and rejected or accepted), evidence weighing using thought records (i.e., identifying a key hypothesis and examining the evidence that supports it and that which does not support it), and core belief continua (i.e., identifying a core belief about the self and placing it on a continua between worst and best exemplars of that category). As in all cognitive restructuring, the goal is for the client and therapist to develop hypotheses that best account for all relevant internal (e.g., memories, body sensations) and external information, as opposed to that which the OCD system makes available in the moment. There are numerous excellent resources for cognitive restructuring strategies for specific subtypes of OCD (e.g., Antony et al., 2007; Bream et al., 2017; Munford, 2004, 2005; Purdon & Clark, 2005; Rachman, 2006; see also Vol. 1, Chapter 8 of this book). Treatment can readily combine ERP with cognitive restructuring, and between-session work typically involves both exposure exercises as well as thought records for obsessive concerns and the need to perform the compulsion. Once the client has become adept at responding to the obsessive concern with relative indifference and has a host of new experiences that disconfirm previously held ideas about the meaning of the obsession and the importance of the compulsion, the therapist and client may choose to work on negative schema. Greenberger and Padesky’s (2016) continuum approach works well for this. For example, consider the schema “Maybe I’m incompetent.” The therapist and client can first identify the qualities that contribute to competence. Often clients initially have a very narrow range of criteria by which they evaluate where they stand on the continuum (e.g., financial success). The therapist and client can work to identify other relevant qualities (e.g., being organized and efficient at work, managing a household well) that contribute to evaluations of competence. The therapist and client can then draw a line anchored at the left by “least competent person” and at the right by “most competent person” (e.g., Hitler and Mother Teresa, respectively), and then have the client identify people they know who would fall toward the left and right anchors, such as a coworker whose lack of initiative and knowledge created a lot of work for others on the left and the leader of their church on the right. The client then plots friends, spouse, and family members, and then finally themselves. Given that people tend to associate with others who share their values, clients invariably end up plotted in the vicinity of the most important people in their lives. This makes the initial statement of the schema less tenable. It also presents the opportunity for some behavioral experiments. For example, the client in this case can be tasked with recognizing and recording indications of her competence and bring a broad range of information to bear on that judgement. Ms. K., for example, soon recognized that she tended to ignore or discount indications of competence.

OUTCOME DATA CBT for OCD is generally efficacious. In their authoritative meta-analysis, Öst et al. (2015) found that CBT had a large effect size of 1.33 compared with placebo. In a large-scale study comparing group treatment with “pure” cognitive therapy (CT), ERP, and wait-list control, McLean et al. (2001) found that ERP was marginally more effective than CT both post-treatment and at a 3-month follow-up, and that both were superior to no intervention. However, there were more dropouts in the ERP condition. They suggested that CT in group format may not be the most ideal means of offering treatment and that there may be advantages to offering CT individually. Warren and Thomas (2001) reported an 84% treatment response with ERP + cognitive restructuring in a routine clinical practice setting, suggesting that the treatment is fairly generalizable to settings at which most people receive their care. Van Balkom et al. (1998) compared the efficacy of adding CT or ERP to medication (fluvoxamine) at Week 9 to that of each psychotherapy alone and to a wait-list control. All treatment groups were found to be equally effective as compared with the wait-list control. In a double-blind, multisite treatment efficacy study comparing the relative and combined effects of ERP (with discussion of appraisal during exposure) and clomipramine, Foa et al. (2005) found that ERP and ERP + clomipramine had completer response rates of 86% and 79%, respectively, and were equal in efficacy but superior to a placebo. In their meta-analysis of CBT for anxiety disorders, Hofmann and Smits (2008) found that CBT relative to placebo had a strong effect size of 1.37, and in fact was more efficacious in treatment of OCD than most other anxiety disorders. In their comprehensive review of the treatment efficacy literature, McKay et al. (2015) concluded that there is considerable evidence for the efficacy of ERP-based CBT, although they note that ensuring adherence to exposure is critical to outcome.
MECHANISMS OF CHANGE Rhéaume and Ladouceur (2000) examined change in appraisal of the obsession in relation to changes in the frequency of checking rituals in participants receiving ERP versus CBT in a small (N = 15) time series analysis. They found that for all those in the ERP group and for one third of those in the CBT group, change on at least one type of appraisal preceded a decrease in checking rituals, although for each participant, decreased checking rituals also preceded change in appraisal at least once. Wilhelm et al. (2015) found that beliefs about the need for perfection and for certainty and schemas relevant to dependency and incompetence mediated treatment response. These findings support the link between appraisal and compulsions asserted by cognitive models, and they also suggest that changes in appraisal and core beliefs may actually cause change in use of compulsive strategies. Thus, appraisal appears to play an important role

in treatment success. Of course, exposure may also operate on more general constructs, such as self-efficacy, and improved flexibility may improve interpersonal relationships, which can alleviate mood symptoms.
APPLICATION TO DIVERSE POPULATIONS In their comprehensive review of transcultural aspects of OCD, Fontenelle et al. (2004) concluded that its core features are consistent across cultures with little variation, but the content of obsessional concerns may vary. For example, there is a preponderance of religious and aggressive obsessions in middle eastern countries and Brazil. Thus, the CBT model of OCD should apply well to people from all cultures. However, as in any treatment, it is important for the therapist to identify their own culturally based assumptions and be sensitive to cultural differences in their clients that can have an impact on treatment, while at the same time not assuming that the client conforms to the norms of their culture. Therapists best be sensitive to and aware of salient cultural differences, such as gender roles, responsibilities and obligations to family, understanding of and attitudes toward mental health, and understanding of and attitudes toward professionals. The “bottom line” is that therapists will do well to identify and avoid acting solely on their own cultural assumptions. It is important to work within the client’s value system, particularly when developing exposure exercises. As discussed earlier in the chapter, compulsions may be an expression of important values. People with strong religious observance may experience certain obsessional content as especially repugnant, believing that even the thought’s occurrence is sinful. For clients who believe that having a sinful thought is equivalent to sinning, the therapist and client need to focus on the overvalued and excessive meaning and importance of the thought; the client may be permitted to engage in appropriate atonement, just as a client may engage in a “normal” hand wash after using the toilet. In some religious traditions, viewing pornography is proscribed, and yet it is not uncommon for therapists to include viewing pornography as part of exposure to repugnant obsessions. The client is best served if the therapist is aware of the client’s values and works creatively to develop exposure exercises and behavioral experiments that achieve new learning but do not compromise important values.
CONCLUSION OCD is heterogenous in its presentation and can be very complex, with numerous factors involved in the persistence of both obsessions and compulsions. However, with careful assessment of the idiographic presentation of the symptoms and the factors in their persistence and use of a strong case formulation as a compass in each session, cognitive and behavioral techniques, particularly
Obsessive-Compulsive Disorder 91
ERP, can be very effective. A key to successful treatment is helping the client overcome obstacles to fully engaging in exposure, such as family factors, fear of compromising valued goals, and core beliefs that are activated by failing to do compulsions. Although there are many resources on conducting ERP, not as many focus on development of a comprehensive case formulation, particularly identification of core beliefs and assumptions, and the factors involved in the persistence of compulsions, such as repetition and memory confidence.

n the initial days and weeks after a traumatic event such as physical or sexual assaults, terrorist attacks, severe accidents, disasters, or war zone experiences, most people will experience at least some symptoms of posttraumatic stress disorder (PTSD) such as intrusive memories, sleep disturbance, feeling emotionally numb, or being easily startled (Rothbaum et al., 1992). Most people will recover in the following months, but for some the symptoms persist, often for years (Kessler et al., 1995). What prevents these people from recovering? Cognitive behavioral theories of PTSD have identified factors that prevent change (e.g., Ehlers & Clark, 2000; Foa & Rothbaum, 1998; Resick & Schnicke, 1993) and can be successfully addressed in cognitive behavior therapy.1,2

therapies (CBT) for phobias and other anxiety disorders had already been developed (for a review see Öst, 2008). Research on the treatment of PTSD benefited from these advances and led to the development of a range of effective CBT programs for PTSD. Keane’s and Foa’s groups (Foa et al., 1991; Keane & Kaloupek, 1982) pioneered the systematic application of in vivo exposure and imaginal exposure to the treatment of PTSD. Resick and Schnicke (1992) were among the first to apply principles of cognitive therapy to PTSD. Several other authors developed further treatment programs that involved a range of exposure and cognitive interventions (e.g., Blanchard et al., 2003; Bryant et al., 1998, 2008; Marks et al., 1998; Tarrier et al., 1999). Besides these trauma-focused CBT (TF-CBT) programs, other CBT experts applied principles of anxiety and stress management to the management of symptoms of PTSD (e.g., Veronen & Kilpatrick, 1983; Meichenbaum, 1997). Early exposure treatments build on the hypothesis that exposure would facilitate extinction of conditioned responses to trauma reminders and reduction of emotional and physiological responses to trauma memories through habituation (e.g., Keane & Kaloupek, 1982). Avoidance behaviors are thought to prevent extinction of the conditioned responses. There is evidence that people with PTSD show delayed extinction and overgeneralized conditioned responses in conditioning studies, and that delayed extinction predicts subsequent PTSD when exposed to trauma (see Lissek & van Meurs, 2015, for a review). However, several theorists pointed out that conditioning alone is insufficient in explaining all the symptoms of PTSD, including the features of reexperiencing symptoms that are central to the disorder. Several theorists proposed that (a) features of trauma memories, (b) negative meanings of the trauma (interpretations, appraisals, beliefs), and (c) avoidance play a role in maintaining PTSD symptoms. Foa and colleagues proposed an emotional processing theory of anxiety disorders and PTSD (e.g., Foa & Kozak, 1986; Foa & Rothbaum, 1998) that forms the theoretical framework for prolonged exposure (PE). They postulated a specific fear structure—a network of associations in memory—that includes excessive stimulus and response elements as well as pathological meaning elements. For example, a survivor of a motor vehicle accid ent may associate the color of the car that hit them and difficulties breathing (as experienced when the airbag opened) with danger and respond to them with anxiety. The fear structure of trauma survivors with PTSD is also thought to include two basic dysfunctional cognitions, namely, the world is completely dangerous (e.g., “It is dangerous to drive”) and the self is totally incompetent (e.g., “I can’t handle any stress, my PTSD symptoms mean that I am going crazy”). According to Foa and Kozak (1986), the fear structure can be changed by activating it and presenting information that is incompatible with its elements (e.g., habituation to driving through prolonged exposure) so that it is integrated into the fear structure to replace pathological elements with realistic ones (e.g., “driving is no more dangerous than it was before the accident”). Resick and Schnicke (1993) proposed that changes in cognitive schemas are central to the understanding and treatment of PTSD. They suggested that
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 101
although cognitive accommodation (modification of existing cognitive schemas) is necessary to integrate the traumatic event, people with PTSD overaccommodate trauma-relevant information by inaccurate and overgeneralized belief changes such as “people are either totally in control or out of control of life events.” They may also show inappropriate assimilation by modifying the perception of the trauma to sustain their previous beliefs. For example, people with PTSD may conclude that an assault was their fault because of a prior assumption that people get what they deserve because the world is fair. They may mistakenly attribute the cause of the assault (i.e., agency) to themselves and thus inappropriately assimilate it into the preexisting fair world schema. The personal meanings of trauma and their close relationship with features of trauma memories are central to Ehlers and Clark’s (2000) cognitive model of PTSD. This model is described in greater detail below as an example that illustrates the close link between theory and practice in evidence-based TF-CBT programs.
COGNITIVE BEHAVIORAL TREATMENTS FOR PTSD The current evidence suggests that several versions of individual trauma-focused cognitive behavior therapy (TF-CBT) are highly effective and are therefore recommended as first-line treatments for PTSD. On the basis of a systematic review, the APA Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder (PTSD) in Adults (2017) strongly recommend individual cognitive processing therapy (CPT; e.g., Resick & Schnicke, 1992; Resick et al., 2002), cognitive therapy (CT; e.g., Ehlers et al., 2005, 2014), prolonged exposure therapy (PE; e.g., Foa et al., 1991, 2005) and cognitive behavioral therapy (CBT) that combines imaginal exposure, in vivo exposure, and cognitive work (e.g., Blanchard et al., 2003; Bryant et al., 2008). Eye movement desensitization and reprocessing (EMDR; Shapiro, 1989), brief eclectic psychotherapy (BEP; Gersons et al., 2015), and narrative exposure therapy (NET; e.g., Neuner et al., 2008), a CBT protocol developed for refugees, are conditionally recommended. Other recent guidelines such as the Clinical Practice Guidelines of International Society for Traumatic Stress Studies (2019) and the UK National Institute for Health and Care Excellence (NICE guidelines (2018) make similar recommendations. While the different TF-CBT programs differ in their emphasis on certain treatment procedures, they overlap in treatment targets and hypothesized mechanisms. Schnyder et al. (2015) suggested that effective trauma-focused psychological treatments have the following six common ingredients: • Psychoeducation: Therapy usually starts with psychoeducation about the nature and course of posttraumatic stress reactions and normalizes clients’ reactions to their traumas. • Exposure: While all TF-CBT programs facilitate the client’s engagement with the trauma memories by talking about the trauma and its meaning, they differ widely in the amount of exposure to trauma memories. In imaginal
102 Ehlers and Wild
reliving, a core technique in PE, clients visualize what happened during the trauma while giving a verbal account of what is happening, including their own thoughts, emotions, and reactions. Repeated narrative writing can also be used as an exposure technique (e.g., Blanchard et al., 2003). PE, NET, BEP and many of the TF-CBT programs reviewed in the APA guidelines emphasize repeated exposures, whereas CPT and CT-PTSD emphasize cognitive work. CPT can be delivered effectively without the repeated writing of a trauma narrative that constituted part of the original protocol (CPT-C; Resick et al., 2008). As described below, CT-PTSD (Ehlers & Clark, 2000) uses only a few imaginal relivings and/or the writing of a narrative to access the moments in memory that are linked to the client’s personal negative meanings and to update these with evidence for less threatening meanings. In addition to imaginal exposure, in vivo exposure to situations that the client has avoided since the trauma is another central element of PE, and dismantling studies have shown that it enhances efficacy of TF-CBT (Bryant et al., 2008). CT-PTSD includes in vivo behavioral experiments designed to test a client’s appraisals, including overgeneralized appraisals of danger. • Changing personal meanings: While all TF-CBT programs aim to change negative meanings of the traumas, they use different methods to achieve this aim. For example, in PE, the emphasis is on repeated imaginal exposures, followed by a discussion of what the client has learned from the exposure. In CPT and CT, negative meanings of the trauma for the client’s view of themselves, other people, and the future are the focus of treatment and addressed with a range of techniques as described below. • Dealing with a range of emotions: Early PTSD theories and treatments emphasized the role of fear in PTSD. However, guilt, shame, anger, grief, or sadness are also common and addressed in most TF-CBT programs. Cognitive therapy programs build on the hypothesis that different emotions have different underlying beliefs or appraisals, which are identified and targeted in treatment. • Emotion regulation: Schnyder et al. (2015) also suggested that traumafocused treatments improve emotion regulation and coping skills. Some programs include skills training designed to help clients tolerate the exposure, such as breathing training in PE (Foa & Rothbaum, 1998) or relaxation in BEP (Gersons et al., 2015). Two treatments that were developed for PTSD related to childhood abuse include a period of skills training before exposure to the trauma memories: training in affective and interpersonal regulation in STAIR/MPE (Skills Training in Affective and Interpersonal Regulation plus Modified Prolonged Exposure; see Levitt & Cloitre, 2005), or training in distress tolerance in Dialectic Behavior Therapy for PTSD (Steil et al., 2011, 2018). However, other efficacious treatments such as NET or CT-PTSD do not include such skill training. • Changing memories: Schnyder et al. (2015) suggested that the creation of a coherent narrative of the trauma is another common ingredient of effective
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 103
trauma-focused treatments. For clients with multiple events, a timeline can help the client see the traumas in the context of other events in their lives (e.g., in NET, CT-PTSD). Besides the specific treatment components, it is important to note that TFCBT shares nonspecific factors common to all psychological treatments: therapist support and a trusting relationship where clients feel safe and understood, the generation of hope through the treatment rationale and the therapist’s encouragement, and the client’s commitment to spend time and take action to get better. These are likely to contribute to changes in cognitions such as “I cannot trust anyone” or “My life is ruined” and to a reduction of avoidance and other behaviors that maintain PTSD, which thus contributes to improvement.
AN EXAMPLE OF TRAUMA-FOCUSED CBT: COGNITIVE THERAPY FOR PTSD Ehlers and Clark’s (2000) model suggests that PTSD develops when individuals process the traumatic experience in a way that gives rise to a sense of serious current threat, which is accompanied by high arousal and strong negative emotions such as guilt, shame, anger, or fear. The sense of current threat is driven by two key processes (see Figure 4.1).3 First, excessively negative appraisals (i.e., personal meanings) of the trauma and/or its sequelae (e.g., reactions of other people, physical consequences of the trauma, initial PTSD symptoms) that extend beyond what anyone would find threatening/horrific about the event. People with PTSD typically experience a range of negative emotions, which depend on the type of appraisal (Ehlers & Clark, 2000). Perceived external threat can result from appraisals about impending danger (e.g., “Nowhere is safe,” “I cannot trust anyone”), leading to excessive fear, or appraisals about the unfairness of the trauma or its aftermath (e.g., “I will never be able to accept that the perpetrator got away with it”), leading to persistent anger. Perceived internal threat often relates to negative appraisals of one’s behavior, emotions, or reactions during the trauma or to the perpetrators’ or other people’s humiliating or derogatory statements, and may lead to shame (e.g., “My actions are despicable,” “I am a bad person”) or guilt (e.g., “It was my fault”). A common negative appraisal of consequences of the trauma in PTSD is perceived permanent change of the self or one’s life (e.g., “I have permanently changed for the worse”), which can lead to sadness and hopelessness. In the case of individuals who have experienced multiple trauma, personal meanings tend to become more generalized (e.g., “I am worthless,” “I do not matter,” “I deserve bad things happening to me”), leading to an enduring sense of degradation, defeat, or low self-worth. The appraisals Video illustrations and treatment materials are available at https://oxcadatresources. com.

can become more embedded in a person’s belief systems over time. For example, if an early life trauma has led a person to feel that they are damaged in some way or unlucky in life, experiencing further trauma is likely to confirm this belief. The second source of perceived current threat are characteristics of trauma memories. According to Ehlers and Clark (2000), the subjectively worst moments of the trauma are poorly elaborated in memory; that is, poorly integrated into the context of the trauma and within the context of previous and subsequent experiences. This includes information from the trauma itself that changes the meaning of these moments (e.g., that they were forced to comply with the perpetrator and that is why they did not fight back). As a consequence, people with PTSD remember the trauma in a disjointed way. When they recall the worst moments, they typically do so without much contextual information; in particular, it is difficult for them to access information that could correct the impressions they had or predictions they made at the time (e.g., “I am going to die and my children will be alone”). In other words, they do not naturally update their memory for these moments with what they know now (e.g., “I survived and am still looking after my children”). This disjointed, decontextualized recall has the effect of inducing a sense of threat similar to the threat they experienced during these moments and making them relive the same emotions and high arousal as though the trauma were reoccurring now rather than being a memory from the past (Ehlers et al., 2004). This includes “affect without recollection” where people with PTSD reexperience emotions and show behaviors from the trauma without realizing that they are responding to a memory. Ehlers and Clark (2000) also noted that intrusive trauma memories and other reexperiencing symptoms are easily triggered in PTSD by sensory cues that overlap perceptually with those occurring during trauma (e.g., similar sounds, colors, smells, shapes, movements, or bodily sensations) and often do not have a meaningful relationship with the trauma. They suggested that this is a result of cognitive processing during trauma when people are attuned to perceptual features of the experience (i.e., data-driven processing), leading to strong perceptual priming, which lowers the threshold for spotting similar perceptual patterns in the environment. Through learned associations, the stimuli become associated with strong affective responses, which can generalize to other similar stimuli. The two processes (i.e., perceptual priming and associative learning) are thought to lead to easy detection of similar stimuli in the individual’s environment and poor discrimination from those encountered during the trauma (in particular, those that share common perceptual features). According to Ehlers and Clark (2000), the symptoms are maintained because people with PTSD use understandable but unhelpful cognitive strategies and behaviors to control the perceived current threat or their PTSD symptoms. These correspond in meaningful ways to the problematic appraisals they may
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 105
have about their trauma, symptoms, or future safety. The strategies include rumination, effortful suppression of memories, avoidance of reminders, safety behaviors (i.e., excessive precautions), and substance use. These cognitive strategies and behaviors prevent change in the unhelpful appraisals or nature of a person’s trauma memories and may increase symptoms, thereby keeping the sense of current threat going and maintaining PTSD. Figure 4.1 illustrates the three factors (i.e., appraisals, memory characteristics, cognitive/behavioral strategies) that maintain a sense of current threat and PTSD symptoms according to Ehlers and Clark’s (2000) model. Cognitive therapy for PTSD (CT-PTSD) targets these three factors. The model serves as the framework for an individualized formulation of the client’s problems and treatment. The model suggests three treatment goals: • Modify excessively negative appraisals (meanings) of the trauma and its sequelae. • Reduce reexperiencing by elaboration of trauma memories and discrimination of triggers. • Reduce behaviors and cognitive strategies that maintain the sense of current threat.

Core treatment procedure (described in greater detail below) in CT-PTSD includes4: • individualized case formulation—therapist and client collaboratively develop an individualized version of Ehlers and Clark’s (2000) model of PTSD, which serves as the framework for therapy. Treatment procedures are tailored to the formulation. • reclaiming/rebuilding your life assignments from the first session onwards to address the client’s perceived permanent change after trauma, which involves reclaiming or rebuilding activities and social contacts. • changing problematic appraisals of the traumas and their sequelae through guided discovery, behavioral experiments, and surveys. • updating trauma memories is a three-step procedure that includes (a) accessing memories of the worst moments during the traumatic events and their currently threatening meanings, (b) identifying information that updates these meanings (either information from the course of events during the trauma or from cognitive restructuring and testing of predictions), and (c) linking the new meanings to the worst moments in the memory. • discrimination training with triggers of reexperiencing involves systematically spotting idiosyncratic triggers (often subtle sensory cues) and learning to discriminate between “Now” (cues in a new safe context) and “Then” (cues in the traumatic event). • a site visit to complete the memory updating and trigger discrimination. • dropping unhelpful behaviors and cognitive processes, which commonly includes discussing their advantages and disadvantages and behavioral experiments where the patient experiments with reducing unhelpful strategies such as rumination, hypervigilance for threat, thought suppression, and excessive precautions (safety behaviors). • a blueprint that summarizes what the client has learned in treatment and includes plans for dealing with anniversaries and any setbacks. Format of Treatment CT-PTSD is usually delivered in up to 12 weekly individual treatment sessions for clients who reexperience a small number of traumas, and more sessions (usually up to 20) for clients with multiple traumas and complex presentations. Therapists should allow 90 minutes for sessions that involve work on trauma memories so that the client has time to refocus on the present before they leave. Weekly measures of PTSD symptoms, depression, and cognitive processes (appraisals, memory characteristics, responses to intrusive memories, Video extracts of the procedures and therapy materials can be accessed at https://oxcadatresources.com.

and safety behaviors) are helpful in monitoring the effects of interventions and spotting remaining problems. An alternative is daily intensive treatment (2 to 4 hours per day) for up to 7 working days, which is also effective (Ehlers et al., 2014). Guidance for remote delivery of CT-PTSD via videoconferencing or telephone is found in Wild et al. (2020). Therapeutic Style and the Therapeutic Relationship The therapeutic style in cognitive therapy is collaborative and centers on guided discovery. Client and therapist work together like a team of detectives who set out to test how well the client’s perceptions and ideas match reality. Together, they consider the client’s cognitions like hypotheses, exploring and evaluating the evidence the client has for and against them. The aim is to collaboratively generate a less threatening alternative interpretation. Socratic questioning is essential in this process of guided discovery and involves the therapist gently asking questions that help the client to consider their problems from different perspectives, drawing their attention to information that is relevant yet likely outside their current focus, and helping them to reevaluate a previous conclusion or construct a new idea (Padesky, 1993). For example, clients who believe that they are likely to experience another trauma consider the alternative hypothesis that the perceived “nowness” of their intrusive memories gives them the impression that another trauma is likely to occur but is not evidence of an impending trauma. Generating an alternative interpretation (i.e., insight) is usually not sufficient to generate a lasting emotional shift. Therefore, the cognitive therapist will emphasize experiential learning and plan behavioral experiments to test the client’s appraisals, which they will carry out in or out of the office. Behavioral experiments are very important for helping the client experience new evidence against their threatening interpretations. These experiments are often the most compelling tests of a client’s unhelpful appraisals. CT-PTSD follows these general principles with some modifications. Because many clients with PTSD feel they can no longer trust people, therapists need to take extra care to establish good therapeutic relationships and make sure the client feels safe in the therapeutic setting (as subtle trauma reminders can make the client feel unsafe in many situations). Because CT-PTSD focuses on changing cognitions that induce a sense of current threat after trauma, careful assessment of the relevant appraisals is necessary. Clients may have unhelpful beliefs (e.g., perfectionism) that are not relevant to their sense of current threat and thus do not need to be addressed in treating their PTSD unless they hinder the client’s engagement and progress in therapy or are important for maintaining comorbid problems that would interfere with the treatment of PTSD. Importantly, the main problematic appraisals that induce a sense of current threat and that need to be addressed in therapy are usually linked to the worst moments during the trauma. The nature of memory recall and cognitive avoidance influences what clients with PTSD remember about their traumas, which in turn may influence their problematic appraisals. In addition, disjointed recall

makes it difficult to assess the problematic meanings by simply talking about the trauma. It also has the effect that insights from cognitive restructuring may be insufficient to produce a large shift in affect. Thus, work on appraisals of the trauma is closely integrated with work on the trauma memory in CT-PTSD. Developing an Individual Case Formulation and Treatment Rationale At the beginning of treatment, the therapist and client discuss the client’s symptoms and treatment goals and start developing an individualized case formulation.5 The therapist normalizes the PTSD symptoms as common reactions to an extremely stressful event and explains that many of the symptoms are signs that the memory for the trauma is not fully processed yet. The therapist asks the client to give a brief account of the client’s traumas and starts exploring the personal meanings (“What was the worst thing about the trauma?” “What were the worst moments and what did they mean to you?”). The Posttraumatic Cognitions Inventory (PTCI; Foa et al., 1999) is helpful in identifying cognitive themes (i.e., appraisals such as negative view of the self, self-blame, permanent change, and overgeneralized sense of danger) that will need to be addressed in treatment. The therapist also asks the client about the content of their intrusive memories and what they mean to the client. This question is important because intrusions point to moments that are essential for understanding the sense of current threat; they are often the moments that clients reexperience yet omit from their trauma narratives. To identify problematic strategies that contribute to the maintenance of PTSD, the therapist asks the client what strategies they have used so far to cope with their distressing memories. Suppression of memories, avoidance, safety behaviors (i.e., excessive precautions), and numbing of emotions (including substance use) are commonly mentioned, as is rumination (dwelling on the memories). The Response to Intrusions Questionnaire6 (which measures suppression, rumination, and numbing; e.g., Ehring et al., 2008) and Safety Behaviours Questionnaire (which assesses excessive precautions; Dunmore et al., 2001) can help to identify strategies that need to be reduced in therapy. The therapist then uses a thought suppression experiment (asking the client to try hard not to think about an image such as a green rabbit or a black and white cat sitting on the therapist’s shoulder) to demonstrate that suppressing mental images has paradoxical effects. After discussing this experience, the therapist encourages the client to try to experiment with letting intrusive memories come and go during the next week (an exception to this homework assignment are clients who spend much time ruminating about the trauma, as they need to learn the distinction between intrusive memories and rumination first). The therapist uses the information gathered so far to develop an individualized case conceptualization and treatment plan with the client, which relates to the three main processes (appraisals, memory, and maintaining cognitive Adapted with permission from Ehlers and Wild (2015).

strategies/behaviors) in the model and contains the following core messages in individualized form using the client’s words as much as possible (adapted from Ehlers, 2013): • Many of the client’s current symptoms are caused by problems in the trauma memories. Therapy will help the client to get the trauma memories in a shape in which they no longer pop up as frequent unwanted memories. They will feel like memories of the past rather than something that is happening now. • The memories of the client’s traumas and what happened in their aftermath influences the client’s current view of their self and the world. The client perceives a threat from the outside world, a threat to their view of themselves, or both. In therapy, the therapist and client will discuss whether these conclusions are fair representations of reality and will consider the possibility that the trauma memories color their perception of reality. • Some of the strategies that the client has used to control the symptoms and threat are understandable but counterproductive and maintain the difficulties the client is having. In therapy, the client will experiment with replacing these strategies with other behaviors that may be more helpful. The graphic presentation of the treatment model shown in Figure 4.1 is usually not presented to the client, as it is quite complex. Instead, different parts of the model, such as the vicious circle between intrusive memories and memory suppression, or the relationship between beliefs about future danger, safety behaviors, and hypervigilance may be drawn out for the client to illustrate particular maintenance cycles that the client is trying to change. Modifying Excessively Negative Appraisals of the Trauma and Its Sequelae Reclaiming/ Rebuilding Your Life Assignments People with PTSD often feel stuck at the time of the trauma and that they have permanently changed for the worse and have become a different person since (e.g., Dunmore et al., 2001).7 Related to this perceived permanent change, clients with PTSD often give up activities and relationships that used to be important to them. This withdrawal from previously important activities in the client’s life usually goes beyond avoidance of reminders of the traumatic event. Some activities may not have been possible in the immediate aftermath of the event, and the client has not taken them up again. Giving up these significant activities maintains the perception of permanent change by providing confirmation that the client has become a different person and that their life is less worthwhile since the trauma. Reclaiming/rebuilding your life assignments is discussed in every treatment session. The aim of the initial discussion in the first treatment session is to map the areas where clients would like to reclaim or rebuild their lives.

client then agree on an achievable first step in one of these areas and develop the first homework assignment. The therapist refers to the client’s treatment goals, which usually include an improvement in the ability to work or study and in their relationships. This intervention helps to instill hope that the client will be able to improve their quality of life. It also helps the therapist get an idea of the client’s life and personality before the trauma so that they can build on previous strengths and interests. If clients have lost much of their former lives since the trauma (e.g., loss of significant other or home, life-changing injuries, the trauma occurred when they were very young), it is best to refer to “(re)building your life” as these clients may say they can never get back what was lost, that they never had a life, or that their former life was not one they wish to reclaim. This intervention has some similarities with behavioral activation (Jacobson et al., 2001) but focuses on meaningful and pleasant activities that were lost since the trauma to help clients retrieve specific memories of their former selves and address their sense of permanent change (Kleim & Ehlers, 2008). Changing Meanings of Trauma by Updating Trauma Memories CT-PTSD uses a special procedure to shift problematic meanings (i.e., appraisals) of the trauma—the updating trauma memories procedure.8 This involves three steps: To access the personal Step 1. Identifying threatening personal meanings. meanings of a trauma that generate a sense of current threat, the moments during the trauma that create the greatest distress and sense of “nowness” during recall (hot spots) are identified through imaginal reliving (Foa & Rothbaum, 1998) or narrative writing (Resick & Schnicke, 1993), and through discussion of the content of intrusive memories. The personal meanings of these moments are explored through careful questioning (e.g., “What was the worst thing about this?,” “What did you think was going to happen?,” “What did this mean to you at the time?,” “What does this mean to you now?,” “What would it mean if what you feared most did happen?”). It is important to ask direct questions about clients’ worst expected outcomes, including their fears about dying, to elicit the underlying meanings, as this guides what information is needed to update their trauma memory. Imaginal reliving and narrative writing both have particular strengths in working with trauma memories, and the relative weight given to each in CT-PTSD depends on the client’s level of engagement with the trauma memory and the length of the event. In imaginal reliving (Foa & Rothbaum, 1998), clients visualize the traumatic event (usually with their eyes closed), starting with the first perception that something was wrong and ending at a point when they were reasonably safe again (e.g., the assailant left; being told in hospital that they were not paralyzed). Clients describe (usually in the present tense) moment by moment what is happening in the visualized event, including what they are feeling and thinking. This technique is powerful in facilitating emotional engagement with the memory and accessing details of the memory, Adapted with permission from Ehlers and Wild (2015).

Cognitive Behavior Therapies for Posttraumatic Stress Disorder 111
including emotions and sensory components. The therapist facilitates controlled engagement with the trauma memory so that the client maintains awareness of the present surroundings. In CT-PTSD, the therapist will usually guide imaginal reliving of the traumatic event two or three times to access the hot spots with sufficient detail to assess their problematic meanings and then will move on to the steps of updating their meaning. This is different from prolonged exposure therapy, in which more sessions are devoted to reliving the traumatic event (Foa & Rothbaum, 1998). Identifying hot spots and their meanings may take longer if clients suppress their reactions or skip over difficult moments because, for example, they are ashamed about what happened. An alternative method of accessing the personal meanings of the event is writing a narrative (Resick & Schnicke, 1993). This method is used when the traumatic event lasted a long time and reliving the whole event would not be possible. The narrative covers the entire traumatic time period and helps to identify the moments or events with the greatest emotional significance so that their meaning can be explored further. Narrative writing is also particularly suitable if clients dissociate and lose contact with the present situation, are very confused about what happened, or show very strong physical reactions when remembering the trauma (e.g., clients who were unconscious during parts of the trauma may feel very faint; see Murray et al., 2020 for details of the treatment of PTSD following treatment in intensive care). Writing a narrative on a whiteboard or computer screen with the support of the therapist can help introduce the necessary distance for the client to take in that they are looking back at the trauma rather than reliving it. Narrative writing is also especially helpful when the client is not clear about aspects of what happened or the order of events because the therapist can interweave a discussion about the different ways the event may have unfolded. Reconstructing the event with diagrams and models and a visit to the site of the trauma (which provides many retrieval cues) can also help in such instances. The narrative is useful for considering the event as a whole and for identifying information from different moments that have implications for the problematic meanings of the trauma and for updating the memory (see Steps 2 and 3). After completing therapy, clients at times find it helpful to refer back to their updated narrative when memories are triggered, such as around anniversaries of the trauma. For clients who dissociate and those with high shame or an enduring sense of degradation, trigger discrimination or initial cognitive restructuring may be conducted first to facilitate the memory work. Step 2. Identifying updating information. Once a hot spot and its meaning are identified, the next step is to identify information that provides evidence against the problematic meanings (i.e., updating information). It can be something that the client is already aware of but has not yet linked to the meaning of this particular moment in memory, or it may be something the client remembers during imaginal reliving or narrative writing. Examples include knowledge that the outcome of the traumatic event was better than expected (e.g., the client did not die, is not paralyzed), information that explained the client’s or other people’s behavior (e.g., the client complied with the perpetrator’s instructions
112 Ehlers and Wild
because he had threatened to kill him; other people did not help because they were in shock), and the realization that an impression or perception during the trauma was not true (e.g., the perpetrator had a toy gun rather than a real gun). Information and explanations from reliable sources or experts (e.g., cars are built in a way that makes explosions after accidents very unlikely; certain distressing procedures in hospitals were done to save the client’s life) can also be valuable in identifying updating information. For other appraisals (e.g., “I am a bad person,” “It was my fault,” “My actions were disgraceful,” “I attract disaster”), guided discovery to generate an alternative perspective is necessary. Cognitive therapy techniques such as Socratic questioning, systematic discussion of evidence for and against the appraisals, behavioral experiments, discussing hindsight bias, pie charts, or surveys are helpful. Imagery techniques can also be helpful in widening the client’s awareness of other factors that contributed to the event or in considering the value of alternative actions. For example, assault survivors who blame themselves for not fighting back during the trauma may visualize what would have happened if they had. This experience usually leads them to realize that they may have escalated the violence further and the assailant may have hurt them even more. Step 3. Active incorporation of the updating information into the hot spots. Once the therapist and client have worked together to identify updating information that the client finds compelling, it is actively incorporated into the relevant hot spot. This can be done as soon as the updating information has been identified for that particular hot spot, for example, in the same session as the first reliving. Clients are asked to bring this hot spot to mind through imaginal reliving or reading the corresponding part of the narrative and then to remind themselves, prompted by the therapist, of the updating information (a) verbally (e.g., “I know now that . . .”), (b) by imagery (e.g., visualizing how one’s wounds have healed, visualizing the perpetrator in prison, looking at a recent photo of the family or of oneself, visualizing the person who died in the trauma in a peaceful place where they are no longer suffering), (c) by performing movements or actions that are incompatible with the original meaning of this moment (e.g., moving about or jumping up and down for hot spots that involved predictions about dying or being paralyzed), or (d) through incompatible sensations (e.g., touching a healed arm). To summarize the updating process, therapist and client create a written narrative that includes the new meanings for each hot spot and highlights them in a different font or color (e.g., “I know now that it was not my fault”). Changing Appraisals of Trauma Sequelae For some clients, a main source of current threat comes from threatening appraisals of the aftermath of the traumatic event. These appraisals are modified by the provision of information, guided discovery with Socratic questioning, and behavioral experiments. For example, some clients believe that intrusive memories are signs that they are going crazy or losing control (e.g., Ehlers et al.,
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 113
1998). Their failed attempts to suppress the intrusions are seen as further confirmation of this appraisal. Others interpret some people’s responses after the event as signs that no one cares for them or understands them or that other people see them as inferior (Dunmore et al., 2001). Such appraisals can be modified through education about the symptoms of PTSD, Socratic questioning, surveys, providing new information, and behavioral experiments. Memory Work to Reduce Reexperiencing Memory work focuses on elaboration and updating trauma memories and discrimination training with trauma triggers. Imaginal Reliving and Narrative Writing The updating trauma memories procedure described above helps elaborate the trauma memory. Retrieving the memory and talking about it helps to make it appear less vivid and intrusive. Clients may observe that some of the sensory impressions from the trauma fade away (e.g., colors or taste fading). When the hot spots have been successfully updated, clients usually experience a large reduction in reexperiencing symptoms and negative emotions and an improvement in sleep (Woodward et al., 2017). Identification and Discrimination of Triggers of Reexperiencing Symptoms Clients with PTSD often report that intrusive memories and other reexperiencing symptoms occur “out of the blue” in a wide range of situations.9 Careful detective work usually identifies sensory triggers that clients have not been aware of (e.g., particular colors, sounds, smells, tastes, touch, body posture, or movement). To identify these subtle triggers, client and therapist carefully analyze where and when reexperiencing symptoms occur. Systematic observation by the client and the therapist in the session and through homework is usually necessary to identify all triggers. Once a trigger has been identified, the next aim is to weaken the link between the trigger and the trauma memory. Weakening the link involves several steps. First, the client learns to distinguish between “then” and “now”—that is, to focus on how the present triggers and their context (i.e., now) are different from the trauma (i.e., then). This leads them to realize that there are more differences than similarities between then and now, that now is very different from the trauma, and that they are responding to a memory of then, not current reality (now). Second, intrusions are intentionally triggered in therapy so that the client can learn to apply the then-versus-now discrimination. For example, traffic accident survivors may listen to sounds such as brakes screeching, collisions, glass breaking, or sirens, that remind them of their car accidents. People who were attacked with a knife may look at a range of metal objects. People who were shot may listen to the sounds of gunfire generated on a computer. Survivors of bombings or fires may Adapted with permission from Ehlers (2013).

look at smoke produced by a smoke machine or a cigarette. People who saw a lot of blood during the trauma may look at red fluids. The then-versus-now discrimination can be facilitated by carrying out actions that were not possible during the trauma (e.g., performing movements that were not possible in the trauma, touching objects or looking at photos that remind them of their present life). Third, clients apply these strategies in their natural environments. When reexperiencing symptoms occur, clients remind themselves that they are responding to memories. They focus their attention on how the present situation is different from the trauma and may carry out actions that were not possible during the trauma. Site Visit A visit to the site of the trauma completes the memory work.10 This visit is done in person where possible or via Google Street View or Google Earth if not (e.g., if the trauma happened in another country). Visiting the site can help correct remaining problematic appraisals because the site provides many retrieval cues and helps access further information to update the appraisals. The site visit also helps complete the stimulus discrimination work. Clients realize that the site now is very different from then, which helps place the trauma in the past. Imagery Work Imagery can be a powerful way to update hots spots (e.g., visualizing a person who died at peace, visualizing how the body has healed/renewed itself after the trauma). In addition, if reexperiencing symptoms persist after successful updating of the client’s hot spots and discrimination of triggers, imagery transformation techniques can be useful. The client transforms the trauma image into a new image that signifies that the trauma is over. For example, with the help of the therapist, a client may transform their image of impact in a car accident to an image of a recent birthday celebration with their children to signify that the client is safe now, their trauma is in the past, and their fears that their children would lose a parent did not happen. Transformed images can provide compelling evidence that the intrusions are a product of the client’s mind rather than perceptions of current reality. Image transformation is also particularly helpful with intrusions that represent images of things that did not actually happen during the trauma (e.g., transforming images of the future that represented their worst fears such as images of a client’s children growing up sad and alone or images of people’s reactions at their funeral). Dropping Dysfunctional Behaviors and Cognitive Strategies The first step in addressing cognitive strategies and behaviors that maintain PTSD is usually to discuss their problematic consequences.11 Sometimes these consequences can be demonstrated directly by a behavioral experiment.

example, the effects of selective attention to danger cues can be demonstrated by asking the client to attend to possible signs of danger unrelated to the trauma. An assault survivor may be asked to stand by a busy road for a few minutes and attend to signs of potentially risky driving. Clients find that this exercise makes them more aware of a range of possible dangers. They then reflect on what this means for their own efforts to scan for signs of danger, typically specific to their trauma, and consider the possibility that the world may not be as dangerous as they assumed. They discuss with the therapist the alternative hypothesis that their intrusive trauma memories lead to the impression that they are in danger. This discussion leads to further behavioral experiments in which they test their appraisals. For example, a person may test “If I do not look carefully for people who look like the assailant, I will be attacked again” by walking to a local shop whilst dropping their hypervigilance and any safety behaviors. They are encouraged to use the then-versus-now discrimination to deal with any reexperiencing symptoms that may be triggered during the experiment. Clients usually predict a very high chance of being attacked and are surprised to find that no one attacked them. Note that the focus of the discussion is on whether the prediction was correct rather than on anxiety levels. In other instances, a discussion of advantages and disadvantages of the strategy is a helpful start. For example, when discussing rumination with the therapist, a client may generate the perceived advantage that dwelling on questions like “Why did it happen to me?” and “If I had done X, could I have prevented the trauma from happening or influenced the outcome?” will help to prevent another trauma. The client may then reflect on the fact that the rumination has not generated any answers, makes them feel worse, wastes a lot of time, and prevents them from moving on with life. This process motivates clients to experiment with moving to other activities when they notice the first signs of rumination. Tailored Treatment As the CT-PTSD case formulation is tailored to each individual, it can be applied to a wide variety of presentations, traumas, and cultural backgrounds and can incorporate comorbid conditions and the effects of multiple traumas. For example, comorbid depression may be related to some of the client’s appraisals of the trauma and other life experiences (e.g., “I am worthless”) and cognitive strategies (e.g., rumination). Comorbid panic disorder may have developed from interpretations of the reexperiencing symptoms (e.g., reexperiencing difficulty breathing leading to the thought “I will suffocate”). And comorbid OCD may be linked to appraisals such as “I am contaminated” and linked behaviors such as excessive washing. The cognitions and unhelpful coping strategies associated with comorbid symptoms are incorporated into the individual case formulation and addressed in cognitive therapy. An example is given in the case illustration. Cultural beliefs may influence an individual’s personal meanings of trauma and their attempts to come to terms with trauma memories in helpful and unhelpful ways. Treatment is tailored to the individual’s beliefs, including their cultural beliefs.
116 Ehlers and Wild
CT-PTSD allows for flexibility in the order in which the core treatment procedures are delivered, depending on the individual formulation and client preference. The memory updating procedure usually has a fast and profound effect on symptoms (Woodward et al., 2017) and is generally conducted in the first few sessions, if possible. For patients with severe dissociative symptoms, training in trigger discrimination is conducted first, and narrative writing is preferred over imaginal reliving. In addition, for certain cognitive patterns, the memory work is prepared through discussion of the client’s appraisals and cognitive processing at the time of the trauma. For example, if clients believe they are to blame for a trauma and their shame or guilt prevents them from being able to describe it fully to the therapist, therapy would start with initial cognitive work (e.g., guided discovery, surveys, spotting self-criticism) to weaken these beliefs sufficiently to enable the client to engage with the memory work of these appraisals. If a client experienced mental defeat (i.e., the perceived loss of all autonomy; Ehlers, Maercker, & Boos, 2000) during an interpersonal trauma, therapy would start with discussing the traumatic situation from a wider perspective to raise the client’s awareness that the perpetrators intended to control and manipulate their feelings and thoughts at the time but are no longer exerting control. For clients displaying complex features of PTSD, other problems may need to be addressed as an initial priority, particularly if reexperiencing symptoms and coping strategies are currently placing a client at risk, for example, as with severe dissociative episodes, excessive use of substances, self-harm, and risky sexual behavior. In addition, a comorbid condition that is a clinical priority and would interfere with the successful or safe delivery of CT-PTSD, such as severe depression with acute suicidal intent or acute psychosis, would require prior treatment. In some cases, it may be necessary to prioritize other problems or events for a few sessions during treatment if they become the client’s primary problem.
SPECIAL CONSIDERATIONS When Should CBT for PTSD Be Offered? In the first 12 to 18 months after a traumatic event, there is a substantial rate of natural remission (up to 50%) from PTSD symptoms (Kessler et al., 1995). This raises the question of when treatment should be given and who should receive early treatment. People with mild PTSD symptoms in the first weeks following trauma have a higher chance of natural recovery than those with severe symptoms (Rothbaum et al., 1992). Thus, a period of active monitoring is recommended (e.g., NICE, 2018)—that is, offering follow-up assessments to check whether the symptoms have declined naturally or whether treatment is indicated. For people with severe PTSD symptoms in the first weeks after trauma or those meeting diagnostic criteria for acute stress disorder, a course of TF-CBT has been shown to be effective (e.g., Bryant et al., 1998; Ehlers et al., 2003; Foa et al., 1995). Individual or group debriefing for trauma-exposed individuals is not effective in preventing PTSD (NICE, 2018).
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 117
Dissociation Dissociative experiences in response to memory triggers are common in PTSD, and clients differ in the severity of dissociation. Some feel unreal, numb, or have ‘out of body’ experiences, but remain aware of their current environment.12 Therapeutic strategies for this milder form of dissociation include normalization of the experience as a common response to trauma (the therapist may want to link dissociation to freezing in animals who face predators); cognitive restructuring and behavioral experiments to modify interpretations of the experience such as “I am going crazy,” “I live in a different reality to other people,” or “The real me died, and I am an alien/ghost now”; and trigger discrimination. It can also be helpful to guide clients who had out-of-body experiences during imaginal reliving to return to their body and perceive the event from the perspective of their own eyes. If clients lose awareness of the current situation completely and feel and behave as if the trauma were happening again, this can involve significant risk to self and others and needs to be assessed carefully. Adaptations of the treatment procedures in CT-PTSD include a strong emphasis on trigger discrimination from the outset of therapy and the use of objects or strategies that remind them of the here and now, helping them stay aware of the present (e.g., touching a small toy or pebble from a beach, using room perfume, watching a recent video of their children, or listening to music when memories are triggered). The therapist explains that strong emotional reactions linked to the trauma can occur without any images of the event itself (e.g., strong urge to leave a situation, strong anger) and guides the client to become increasingly aware that these are signs that trauma memories are being triggered. The work on trauma memory updating is adapted to allow the client to remain aware of the present safe environment. For example, therapist and client may write a narrative on a whiteboard or computer in small steps in combination with stimulus discrimination strategies, and the updates for each hot spot are then included in the narrative in a different color and read out together. Risk to self and others is assessed and precautions are agreed if indicated. Multiple Traumas Many clients with PTSD have experienced more than one trauma, but not all traumas are necessarily linked to their current PTSD.13 To determine which traumas need to be addressed in therapy, the therapist and client discuss which traumas still bother them (i.e., are represented in reexperiencing symptoms or are linked to personal meanings that trouble the client). This discussion also provides a first assessment of problematic meanings that link several traumas. For example, repeated trauma may lead to generalized negative appraisals such as “There is something about me that attracts disaster” or “I deserve bad things to happen to me.” Client and therapist discuss which trauma to start with.

would usually be a trauma that the client currently finds the most distressing or a trauma during which an important problematic meaning originated. The therapist also may assist the client in developing a timeline of their life and trauma history, to facilitate the identification of focal traumas. The therapist also notes whether elements from other traumas come up when the client relives the identified trauma, as these may have influenced its personal meanings. Once the hot spots from the identified trauma have been updated, the therapist checks whether this decreases the reexperiencing of other traumas that carry related meanings. The remaining traumas that are still distressing or relevant for problematic appraisals are then addressed in turn. Dissociation may be pronounced and will need to be addressed with the methods described above. Work on reclaiming/rebuilding the client’s life is especially important after multiple traumas, as these clients may lead very restricted lives and may need much support from the therapist as well as problem solving about how to best build up a social network, reengage in the job market, and so forth. Work on maintaining behaviors is also especially important as clients may show extreme forms of these behaviors (e.g., chronic hypervigilance and complete social withdrawal). For clients with long-standing multiple traumas, additional work on self-esteem may be helpful (e.g., keeping a log of things they did well or positive feedback from others). Physical Problems The injuries contracted in the traumatic event may lead to ongoing health problems that significantly affect the client’s life.14 Chronic pain is common. Sometimes the traumatic event leads to a permanent loss of function, for example, difficulty walking, inability to have children, or blindness. Clients often need help in adjusting to these physical problems and the impact they have on their lives. This may require additional treatment strategies such as pain management or coping strategies similar to those for coping with chronic illness. Cognitive distortions such as overinterpretation or overgeneralization of the negative impact of the loss on their lives (e.g., “I am useless,” “My life is worthless now”) may need to be addressed in therapy. For other clients, the physical injuries may have compromised their appearance, which may have negative effects on their job or social life. They may need support in learning to adapt to these changes. It is also not uncommon for clients to perceive a loss of attractiveness or a disfigurement that is greater than the objective change. For these clients, video feedback is used in CT-PTSD as it helps clients update the image of how they believe they appear to others (which is influenced by the trauma memory) with a more accurate image. Clients watch themselves in a short video recording, with the instruction to watch themselves objectively as if they were another person they do not know. For example, a client who believed that his facial scars were repulsive saw bright Adapted with permission from Ehlers and Wild (2015).
14

red scars when he visualized how he would appear to others. His face was filmed with different red objects in the background. Comparing his face with the objects made him realize that the scars no longer looked red and were much less visible than he had imagined. Surveys are helpful in testing clients’ beliefs about what other people think about their appearance. For example, the client agreed with the therapist that some other people could watch the video recording and answer a series of questions about his appearance, starting with neutral questions and ending with direct questions about the client’s concern: “Did you notice anything about this person’s appearance?” “Did you notice anything about this person’s face?” “Did you notice that he had scars?” “What did you think about the scars?” “How much, out of 100%, did you think he looked repulsive?” The therapist fed back the responses in the following week and the client was relieved to find that no one thought he looked repulsive and most people had not even noticed the scars. Other health problems that existed before the traumatic event may influence the course of treatment. For example, clients with some medical conditions, such as poorly controlled diabetes, may find it hard to concentrate for long periods of time and require shorter sessions or sessions with frequent breaks. Clients with chronic heart conditions may require a more graded approach in recalling the trauma and visiting the site where the trauma occurred than clients who are physically healthy. Comorbidity Many clients with PTSD have comorbid conditions that need to be addressed in treatment.15 Depression that is secondary to PTSD will usually resolve with treatment of the PTSD. However, in some cases, depression may become so severe that it needs immediate attention (i.e., suicide risk) before PTSD treatment can commence. In some trauma survivors (especially after multiple traumas), depression may dominate the clinical picture to the extent that it makes a treatment focus on the trauma impossible and warrants treatment first. Depressive symptoms most likely to interfere with PTSD treatment are severe suicidal ideation, extreme lack of energy, social withdrawal, inactivity, and poor concentration. The first goal in treatment will be to lift the client’s mood sufficiently so that TF-CBT can commence, for example with behavioral activation or antidepressant medication. Anxiety disorders such as panic disorder, agoraphobia, obsessive-compulsive disorder, generalized anxiety disorder, or social phobia may be preexisting conditions or develop as a complication of PTSD. The therapist needs to determine whether the comorbid anxiety disorder needs treatment in its own right. If this is the case, the case formulation and treatment plan will need to integrate the treatment of both the PTSD and the other anxiety disorders. It is not always easy to determine in the initial assessment whether patterns of avoidance are Adapted with permission from Ehlers and Wild (2015).

part of the client’s PTSD or part of another anxiety disorder. An important question is “What is the worst thing that could happen if you . . . (encounter the feared situation, do not take special precautions).” In PTSD, the client’s concern would usually be another trauma (“I will be attacked again,” “I will die in another accident”). Other concerns suggest other anxiety disorders, for example, panic disorder (“I will have a heart attack,” “I will faint”) or social phobia (“I will make a fool of myself,” “People will think I am weird”). It is often difficult to determine whether or not a panic attack or strong anxiety response in a certain situation constitutes a reexperiencing symptom, as clients are usually not aware of the subtle sensory triggers of reexperiencing. In these cases, an ongoing assessment of the need for separate work on the other anxiety disorder is needed as treatment progresses. In most cases with comorbid anxiety disorders, treatment starts with the TF-CBT program. An important exception are clients with panic disorder who believe that a catastrophe will happen if they become very anxious or put their body under stress—for example, believing that they will have a heart attack, will faint, or go crazy. These misinterpretations often need to be addressed before working on the trauma memory as these clients are unlikely to engage in treatment or may drop out if their concerns are not addressed. Many clients with PTSD use alcohol, cannabis, or other substances to numb their feelings or distract themselves from trauma memories. This may include heavy smoking or even consumption of caffeinated beverages in large quantities. Substance misuse is not a contraindication for treatment. Treatment of the PTSD will help clients with reducing their substance use. The therapist will need to incorporate the substance use as a maintaining behavior in the case formulation and address it together with the other maintaining factors in the overall treatment plan. However, if physical substance dependence has developed (i.e., the client has withdrawal symptoms, tolerance, and acquiring and consuming the substances takes up much of the client’s life), withdrawal is usually necessary before the client can benefit from the treatment described here. If in doubt, a useful strategy is to explain to clients with very high substance use that it will interfere with their capacity to process the therapy sessions and to benefit from the treatment. The therapist will need to educate clients about the negative effects of the substance on their symptoms (e.g., alcohol may help the client get off to sleep, but it will lead to more awakenings at night and feeling irritable and emotional the next day; cannabis may make the client feel more unreal or more paranoid; smoking leads to brief relief, then increased anxiety; caffeine can lead to irritability, poor sleep, and poor concentration). The therapist should then ask whether clients would be willing to reduce their substance consumption before treatment commences. Many clients will agree to give it a try if they have the prospect of receiving help for their PTSD. These clients often find that the reduction in substance use in itself has a positive effect on their symptoms. If the client does not feel able to reduce the substance consumption, treatment will need to target the dependence first.

CLINICAL EXAMPLE Lara, a 46-year-old Spanish woman living in the UK, was sexually assaulted in her flat in front of her 10-year-old daughter. During the attack, she was forced to fondle her daughter. The perpetrator, well known to the police, had been on parole following imprisonment for sexually assaulting women. After the attack, he was caught, arrested, charged, and sentenced to life imprisonment. Prior to the attack, Lara had been addicted to heroin for 10 years and had supported herself on and off with prostitution. She had received treatment for drug dependence and had been abstinent from alcohol, drugs, and prostitution for 4 years prior to the trauma. At the time of the assessment, 10 years after the assault, Lara’s daughter was studying at university and Lara was working as a nurse. The diagnostic assessment with the Structured Clinical Interview for DSM-IV (First et al., 1995) showed that Lara was suffering from PTSD, social anxiety, dysthymia, and generalized anxiety disorder, all of which had developed after her attack. Symptoms included unwanted memories of the rape; for example, of her daughter’s face, looking terrified, as she watched what was happening to her. About once a week, she had nightmares about being attacked again. These woke her, and she was unable to return to sleep. Lara avoided thinking about the attack, and she had lost interest in socializing with colleagues, seeing friends, and practicing yoga. She felt distant, numb, and cut off from other people. Lara had difficulty falling and staying asleep, irritability, and difficulty concentrating. She was overly alert and jumpy in response to loud noises. The symptoms that most bothered her were the memories of being raped, which also triggered memories of her work as a prostitute. The intrusions of the trauma and prostitution triggered rumination and confirmed her pretrauma beliefs that she was a disgusting, bad mother, who was careless, selfish, and stupid. After periods of rumination, she felt low and had thoughts of taking her life. Her goals for treatment were (a) to stop the memories of the rape and prostitution, (b) to feel less guilty and ashamed about what happened during the trauma and her prior work as a prostitute, (c) to try yoga again, and (d) to socialize with work colleagues. Case Formulation According to Ehlers and Clark’s (2000) Model The cognitive assessment revealed the following factors that contributed to Lara’s sense of current threat. Appraisals Lara blamed herself for the attack. She believed that she should have been able to prevent the attack, that it was her fault, and that she was careless and stupid (belief rating: 100%). Lara believed that she had let her daughter down by fondling her and that she was a bad mother (90%). She believed that the repetitive nightmares, frequent memories, and inability to stop questioning herself
122 Ehlers and Wild
meant that she was “losing it” and would never recover and socialize with other people (90%). Trauma Memories Lara’s main reexperiencing symptoms included images of her daughter’s terrified face as she was being attacked. The images meant that her daughter Anna was damaged and that Lara had not protected her; that she had let her down. The nightmares were about being attacked again and when she had them, she had periods of dissociation and felt as though the trauma was happening again and that she was about to be raped. As a result, she forced herself to stay awake for the rest of the night. Lara was tearful when she described her worst memory of the rape in the first session. She remembered that she had been forced to fondle her daughter but was unsure how helpful she had been in ending the attack and was unable to access information that revealed she had protected her daughter from being raped. Lara reported that her intrusive images were triggered by seeing photos of her daughter when she was a child, reading news reports of sexual assault, conversations about sexual abuse scandals, fictional TV programs featuring prison life, seeing similar-looking people as the perpetrator, children screaming, and scissors. Sometimes images came out of the blue, suggesting there were triggers she had not spotted yet. Maintaining Behaviors and Cognitive Strategies A range of cognitive strategies and behaviors maintained Lara’s PTSD and low mood: • suppression of trauma-related images and memories • rumination and self-criticism • safety behaviors and hypervigilance • withdrawal from social life and other activities When images of the trauma came to mind, Lara tried hard to push them away. She told herself not to think about the memories, which kept them in mind and triggered periods of rumination, during which she overanalyzed her past, berating herself for drug abuse and prostitution whilst caring for a young child. The rumination and self-criticism made it impossible for her to access information that could help to update the memories and their meanings, and maintained her sense of guilt, shame, and sadness. Her feelings of guilt and shame caused her to withdraw socially, which maintained her low mood. Lara took unnecessary precautions (safety behaviors) to keep herself and her now grown daughter safe. She called her daughter several times a day to check that no one had approached her with threatening behavior. She avoided dating. She was hypervigilant at home, double-locking her doors and checking local news stories to keep up-to-date on crime in the area. When she was
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 123
woken by a nightmare, she avoided going back to sleep, which caused her to feel irritable and have difficulty concentrating the next day. Lara felt ashamed of what the perpetrator had done and ongoing shame linked to her past. She believed people could see that she had been raped and that she was “losing it” when they looked at her. As a result, she avoided eye contact at work, socializing, and taking part in activities, such as yoga, where other people were present. She felt detached from others, felt unsafe when she was around men, and had stopped going out with friends. Comorbid Conditions The cognitive assessment suggested that many of the factors maintaining Lara’s PTSD were also maintaining her social anxiety, dysthymia, and generalized anxiety disorder. Her appraisals that she was a disgusting, bad mother who had failed her daughter and was careless, selfish, and stupid, and her rumination on these self-critical thoughts as well as her withdrawal from friends and previously enjoyed activities maintained her dysthymia. Lara worried about bad things happening and this generalized to situations unrelated to the trauma. She worried about being knocked off her bike on the way to work and sustaining a permanent injury. She worried about her health, her daughter’s health, and the consequences of developing an injury or having poor health, which caused her to worry about finances and her job. Her appraisals that other people could see she was “losing it” and that she had been raped made her anxious around other people. She believed she would say something stupid, which would confirm other people’s view of her as being stupid. Her avoidance of socializing and making eye contact at work maintained her social anxiety. Treatment Lara attended 12 sessions, lasting between 60 and 90 minutes each. Work on Appraisals Interpretation of symptoms. S ome of Lara’s appraisals concerned interpretations of her symptoms: “I’m losing it.” “I’ll never recover and socialize with other people.” These were addressed with the following interventions in Session 1: Normalization of symptoms: Intrusive, distressing memories and nightmares are normal after trauma. They are a sign that we need to work on the trauma memory to help you process it and put it in the past, which will make the memories less intrusive. Information about the nature of trauma memories: Trauma memories often feel like they are happening now and give you a sense that there is immediate danger. For example, one of your trauma memories is seeing your daughter’s terrified face as you were being attacked. This brings back the feeling of danger because when you saw her looking terrified during the trauma, you were in danger. Her terrified face was a sign that you were still in danger. You did not know then how the trauma would end and you believed you
124 Ehlers and Wild
would be killed. The feeling that you are in danger now when the memory comes to mind is coming from the trauma memory. Reclaiming your life assignments. Examples of the activities Lara built up over the course of therapy included (a) yoga poses in a standing position at home for 15 minutes twice a week, then half an hour, then with a friend at her home, and toward the end of therapy, with a friend at the gym, including poses where she lay down, and then by herself at the gym; (b) a telephone chat with a friend, then a coffee with a friend at her house, then in a café, then lunch with colleagues at work; (c) researching courses on training as a yoga instructor; and (d) booking a holiday. These activities helped to reduce the strength of Lara’s belief that she would never recover or socialize again. She was encouraged to focus her attention externally when she tried these activities, paying attention to signs that people were responding to her in a kind and friendly manner, which helped her to feel less anxious around other people. Engaging in activities helped to increase her social contact, improve her mood, and loosen the belief that people could see her past. Self-blame for assault. Lara believed she should have been able to prevent the attack—that it was her fault (100%) and she was careless and stupid (100%). These were linked to particular moments during the assault that were identified with imaginal reliving and updated over two sessions. In Session 2, Lara described the trauma in imaginal reliving. Lara had been living in an area in London with higher than average rates of crime. She had been at home alone with her daughter when someone knocked at the door. The person said they were a police officer investigating a burglary in the area and asked if they could ask Lara a few questions. Lara opened the door, and the man feigning to be a police officer attacked her. He raped her and asked her to fondle her daughter. Lara was lying face down on the floor, and as she moved to start to fondle her daughter, she saw a pair of scissors. She grabbed them, and with all her strength, she pushed the man off her back and chased him out of her flat and down the street. A neighbor called the police and the man was arrested, charged, and imprisoned. To access updating information, the therapist used Socratic questioning, asking the following: “How did you get out?,” “When during the trauma did things change?,” “Did you save your daughter from being raped?,” “What does this say about you as a mother?” Lara realized that although being asked to fondle her daughter was a worst moment during the trauma, it was also a turning point, signifying the moment she was able to turn the situation around and save them. It was in this moment that she saw the scissors and was able to chase the perpetrator away. She realized that although she had briefly fondled her daughter, she had protected her from being raped. The therapist and Lara constructed a pie chart to look at all of the contributing reasons for why the attack happened. Lara was asked to apportion responsibility as a percentage to each factor before apportioning responsibility for her
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 125
own actions. Lara concluded that she was not responsible for the attack and that the responsibility lay with the perpetrator, the police, and the justice system for giving the perpetrator parole when he was still risky to the public. In the next session, Lara relived the hot spot (being asked to fondle her daughter) in imaginal reliving and linked the updating information to this moment in memory. To generate updating information for Lara’s appraisal “I am careless and stupid” (100%), the therapist constructed a survey with Lara in which they wrote a brief description of the trauma and followed it with questions. The survey asked people to rate out of 100% how careless and stupid they would consider someone to be for opening their door to a man stating he was a police officer investigating crime in area. The survey also included questions asking what other people would have done in a similar situation. The therapist reviewed the survey in Session 3. All respondents indicated that they thought the person was 0% stupid and that they would have done the same thing. Lara had predicted that no one would have opened the door and that everyone would have thought a person who fell for the perpetrator’s introduction as a police officer was entirely stupid. Learning that other people would have done the same thing and that they too would have wanted to be helpful to the person claiming to be a police officer helped Lara to reassess her belief, which she rerated as 0%. In the next session, Lara relived the hot spot in imaginal reliving and linked the updating information to it: that it is normal and understandable to open the door to the man claiming to be a police offer, that it is exactly what other people would do, and that it is a sign she is a helpful and concerned citizen. “I am a bad mother.” L ara believed that she had let her daughter down by fondling her (80%) and that she was a bad mother (90%). In Session 3, Lara described in imaginal reliving the moment the perpetrator asked her to fondle her daughter. The therapist elicited the worst meaning of fondling her daughter and Lara revealed that it meant that her daughter was now damaged, that her life was ruined, and that Lara was a disgusting, bad mother. To access updating information, the therapist used guided discovery, asking Lara to describe her relationship with her daughter and her daughter’s relationship with friends and her romantic partner as well as her daughter’s achievements. Lara revealed that Anna thought very highly of her and that she was proud that her mum had been able to achieve so much, having a difficult past with drugs, and that she admired her work as a nurse, saving people’s lives. Lara also described her daughter’s achievements, the main one being that she was studying political science at a respected university. She also had supportive friends and a boyfriend of 2 years whom Lara liked. The therapist asked Lara to write the updating information on a flashcard and take a picture with her phone so that she could remind herself of it. Lara concluded that her daughter was doing well, that she was not damaged, and that her life was not ruined. She rerated her belief that she had let her daughter down as 40%. The therapist then guided Lara to relive the worst moment and to link all of the updating
126 Ehlers and Wild
information they had discovered to the worst moment. Lara described the worst moment with her eyes closed, and in the present tense, she then included the updating information about why the event happened, what other people would have done, and how much Anna had achieved as well as what she thought of Lara. Lara relived the worst moment with updating information a few times in this session. Her rerated belief after linking the updating information to the worst moment in imaginal reliving was 0%. To update the belief that she was a bad mother, the therapist constructed a survey, asking people what they would think of a woman who had been raped in front of her daughter and then forced to fondle her for a few minutes before seeing a pair of scissors and chasing the perpetrator away. They were asked to rate out of 100% how much they believed this woman was a bad mother and to indicate what they think they would have done in similar circumstances. The therapist discussed the results of the survey with Lara in Session 4. An extract from this therapy session is below. THERAPIST: Lara, before we read through the survey results, I’d like to ask
how much you believe you are a bad mother? LARA:
Very strongly. 90%. I feel awful about being forced to fondle Anna during the attack. I let her down completely.
The therapist then read the survey responses out loud to Lara. After each question, she asked Lara how the response made her feel and how they fit with her belief that she was a bad mother. When the surveys had been read, the therapist used Socratic questioning to help Lara reevaluate the belief that she is a bad mother.
THERAPIST: So we’ve read through all the responses from the eight people
who completed the survey. What have you discovered? LARA:
Well, no one rated me as a bad mother. They actually commented on how brave I was during the attack, that I may even have saved my daughter from possible rape and death.
THERAPIST: Exactly, and overall, what did people think of your behavior of
fondling your daughter—did they see it as evidence that you are a bad mum? LARA:
No one thought I was a bad mum for being forced to fondle Anna. Everyone thought that I was brave for grabbing the scissors soon after he made me fondle her and chasing him out.
THERAPIST: Exactly. And what did people think they would have done in a
similar situation?
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 127
LARA:
I was surprised to discover that most people—seven out of eight people—thought they would have been too paralyzed with fear to fight the attacker.
THERAPIST: So no one rated you as a bad mum. All eight people thought you
were brave and that you saved your daughter from being attacked and possibly raped. And seven out of eight people thought they would have been unable to fight back and protect their child in this situation. Lara, I’m wondering what does this say about whether or not you are a bad mum? LARA:
Looking at it this way and hearing about what other people think and would have done, I don’t think I am a bad mum.
THERAPIST: How much out of 100%, do you believe you are a bad mother? LARA:
Much less. About 10%.
THERAPIST: And what makes you a 10% bad mother, Lara? LARA:
The choices I made when Anna was a toddler, choosing to work as a prostitute to support my heroin habit. I feel so ashamed about this.
THERAPIST:
I understand. We’ll look at this in a little more detail in a moment.
To address her self-blame linked to prostitution, the therapist asked Lara what her mental and emotional state was at the time when she was heavily using heroin. Did she have capacity to make healthy choices? The therapist guided Lara to discover that the physiological addiction to heroin gave her little choice for healthy behaviors at the time. The therapist and Lara concluded that when people are in the throes of heroin addiction, their capacity to make healthy choices are limited, that the heroin makes choices for them. Prostitution seemed understandable as a means to pay for the habit and avoid horrendous withdrawal symptoms. To address Lara’s shame linked to prostitution, the therapist used guided discovery and Socratic questioning, illustrated in the therapy extract below. The therapist is aiming to help Lara discover that her choices are more similar than different to other people since this will reduce the sense of shame. THERAPIST: I’d like us to come back to this belief that you’re a bad mother.
Considering the survey we’ve just run through, you’ve rated the belief that you’re a bad mum as 10%. LARA:
Yeah, 10%. It helps to know that other people don’t judge me for being raped in front of Anna and they don’t rate me as a bad mother, but I can’t change that I was a prostitute when she was a toddler.
128 Ehlers and Wild THERAPIST: I can see you feel badly, Lara. I’m wondering what you believe
prostitution says about you as a person? LARA:
I’m weak. I allowed myself to be violated and to be paid for it. I was not true to my values, and I’m clearly different to other people now because I was a prostitute and was addicted to heroin.
THERAPIST: Well, let’s start with “I’m weak.” What have we learned so far
about how the trauma ended? LARA:
I grabbed a pair of scissors and chased the perpetrator out eventually.
THERAPIST: Yes, that’s right, and what did we learn in the survey about what
other people might do if they were in a similar situation? LARA:
Most of the people said they thought they would freeze and would be unable to fight back.
THERAPIST: So you ended the trauma, saving your daughter by grabbing the
scissors and chasing the perpetrator out of your flat. Other people think they would have frozen and been unable to fight back in similar circumstances. How does this fit with being weak? LARA:
Well, it doesn’t, and I know I protected Anna in that situation. But when she was really young, I made money having sex to support a habit and didn’t value the choices I was making then.
THERAPIST: And what have we learned about how heroin drives behavior? LARA:
I now know that my state of mind at the time was unhealthy because of heroin and that my choices were being driven by heroin.
THERAPIST: That’s right and how does this make you feel? LARA:
It helps a bit but it doesn’t change the choice I made to have sex for money.
THERAPIST:
Lara, do you know people or have you heard of people who have carried out acts they don’t value, who weren’t true to themselves and their values and who were paid for it?
LARA:
I don’t know. Maybe. I have a friend who works for a company, I don’t want to say the name, but they are well known for avoiding corporate taxes and employing kids in China in horrid work conditions. He keeps working for them all the same, supporting their productivity.
THERAPIST: And does he value his work or the decision to keep working
for them? LARA:
No, he’d rather work for another company.
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 129 THERAPIST: So why does he keep working for them? LARA:
Because he needs the money. They pay well.
THERAPIST: And did you need the money when you worked as a prostitute? LARA:
Yes, I did.
THERAPIST: Any other people you know or have heard about on TV who go
against their values in the work that they do? LARA:
Well, I think most of the people who work for this company that I mentioned know about their corporate tax evasion and what’s going on overseas and they keep working for them anyway. They employ at least one million people.
THERAPIST: So a lot of people choose to go against their values, to be paid for
work they may not value? LARA:
Yes, that’s true.
THERAPIST: So would this make you more similar or different to other peo-
ple—that you chose to work in an area you did not value so that you could make money? LARA:
I guess that makes me more similar.
THERAPIST: I would agree. Let’s come back to this point you made about
being violated and being paid for it. I understand it makes you feel completely different from other people. Let’s think about this a bit more. Have you heard of women who stay in horrendous marriages and have sex with husbands they do not value or care for because they enjoy a lifestyle they’d otherwise be unable to afford? LARA:
I have heard of this. I don’t know how they do it. Year in, year out.
THERAPIST: So would you say they are choosing to be violated for money? LARA:
Yes, that is what’s happening.
THERAPIST: So the behavior of having sex for money—is this similar or dif-
ferent to some other people? LARA:
It’s similar.
THERAPIST: That’s interesting. And what does this tell us about you, Lara?
Are you similar or different to other people? LARA:
I’m more similar when I look at it this way.
130 Ehlers and Wild
THERAPIST: That’s right. And I’d like us to turn to your addictive behavior for
a moment. I’m wondering if there are habits other than heroin that might be addictive? LARA:
Alcohol. Smoking.
THERAPIST: That’s right. Anything else? LARA:
I don’t know.
THERAPIST: Have you heard of people becoming addicted to video games or
binge watching Netflix series or even being addicted to caffeine—not being able to get through the morning without a cup of coffee? LARA:
I have. But these aren’t harmful though.
THERAPIST: Some behaviors are addictive in the short term and some in the
long term with varying levels of harm. Looking at addiction in this way, would you say that most people have experienced a form of addiction? LARA:
Yes, I hadn’t thought of it like this before. My daughter is addicted to her phone!
THERAPIST: And that is another example of a behavior with addictive fea-
tures. So would you say you are more similar or different to other people? LARA:
Put like this, I am actually more similar.
THERAPIST: I would agree. Considering this new information, Lara, how
much do you believe now that you are a bad mother because you worked as a prostitute in the past? LARA:
I don’t! Let’s say 2%. I don’t think it will ever be 0% because of the situation I was in at the time, but I can see that past prostitution does not make me a bad mum and I am more similar than different to other people.
Memory Work to Reduce Reexperiencing Imaginal reliving, transforming images, and visiting the block of flats where the trauma took place by Google Street View helped Lara to identify hot spots and update the worst meanings linked to each one. She learned that she had done everything possible to protect her daughter and to prevent her from being attacked, and she had been successful in keeping her safe. She learned through updating the memories that her actions were nothing short of heroic and that is how they were seen by people who completed the surveys. In Session 5, Lara learned to transform frightening images with new information. She practiced turning from the image of her daughter’s terrified face to
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 131
an image of her studying at university with friends. The updated image captured the updating information, which was that Lara had protected her from being attacked, that her life was not ruined, and that she was not damaged. In Sessions 6 and 7, Lara explored with the therapist triggers for intrusive memories. Through observation and attention to sensory similarities between possible triggers and the trauma, she spotted a range of triggers she had not noticed before. Examples included lying on her stomach, which she had been forced to do at the time of the trauma; being pushed from behind, which had happened at the time of the trauma; activities which made her short of breath, such as running upstairs or up a hill, since the perpetrator had forced her face down from behind and she had found it difficult to breathe; and sex scenes in television programs and films. The therapist helped Lara discriminate between the triggers today and the trauma in the past, focusing on their differences (stimulus discrimination). In-session work included running up and down stairs whilst focusing on where she was now, how it was different to the time of the trauma, and how her breathlessness signified fitness rather than danger; looking at romantic scenes in everyday television programs and focusing on how the characters were consenting to be close; going out of the office with the therapist with the therapist gently bumping into her from behind; as well as seeking out men who looked similar to the perpetrator and focusing on how these people today were different from the trauma, which helped to discriminate between the triggers today and the past trauma. In Session 8, the therapist guided Lara to revisit the block of flats where she was raped on Google Street View to practice discriminating between then and now. This helped Lara to discover experientially that the trauma was in the past and that the site looked different now. There was nothing visibly dangerous in the Google Street View image of the block of flats, which were captured in daylight in the summer, and the flat doors had been painted blue, which was different to residents’ black doors at the time of the trauma. Work on Maintaining Behaviors and Cognitive Strategies Suppression. The therapist addressed Lara’s maintaining strategies as early as Session 1, beginning with suppression in response to intrusive images and memories. The therapist asked Lara to think about anything she wanted to for 60 seconds except a bunny rabbit with a green bow and floppy ears (thought suppression experiment). Lara discovered that suppressing the rabbit only made it come to mind more often, and that the same was most likely true for the memories she was trying to suppress, which helped her to experiment with dropping suppression as a strategy. Rumination. To address Lara’s rumination and self-criticism, the therapist elicited recent examples when she had ruminated and criticized herself. The memory of her daughter’s terrified face triggered memories of the rape, which then led to memories of herself as a prostitute and triggered episodes of rumination. When the memory came to mind, Lara would question why she was a disgusting, bad
132 Ehlers and Wild
mother who had made selfish choices. She criticized herself for taking up heroin again after she had made it through the pregnancy without it and criticized herself for failing to give Anna a safe environment during her toddler years. The therapist set up a behavioral experiment to test the effect of ruminative thinking versus concrete thinking on her mood. Lara discovered that thinking in a ruminative way made her feel low and led to no plan or action. She spotted that her triggers for rumination were seeing photos of her daughter when she was very young, which triggered the memory of her rape and her prostitution, and lying in bed at night. With the help of her therapist, she learned to spot when she was ruminating and to use the awareness as a cue to break the cycle. She would remind herself of new information with updating imagery and become active when possible with yoga stretches that required her to balance her weight, thus absorbing her full attention. She also spotted her self-critical thoughts and in response, she read the flashcard on her phone, which captured her daughter’s pride and gratitude. She then practiced self-compassion, speaking to herself with the same kindness that she would extend to a friend in similar circumstances. Safety behaviors and hypervigilance. Lara’s safety behaviors, hypervigilance, and avoidance were addressed by considering the hypothesis that her trauma memories made her feel like her daughter was in danger. She experimented with reducing her checking with a series of behavioral experiments incorporating stimulus discrimination in session and for homework. She learned that her daughter’s safety was unrelated to her telephone calls or the trauma, and that focusing on the differences between her life at university and the trauma helped to reduce Lara’s anxiety about her safety. She experimented with reviewing news reports of crime one day and not the next, discovering that checking the reports made her feel more rather than less anxious, which helped her to stop checking altogether. She continued to double lock her doors at home, but she stopped checking whether or not they were locked since she learned that checking kept her mind focused on danger, which made her more anxious. Lara practiced focusing on the here and now and looking at a recent photo of her daughter, reminding herself that they were safe and the trauma was in the past when a nightmare woke her. She then experimented with returning to sleep and discovered that she was able to sleep, that she did not reenter the nightmare, and that overall, she felt less irritable and better able to concentrate the next day. As the trauma memory was updated, the nightmares reduced in frequency. Social withdrawal. Reviewing the responses people gave on her surveys gave Lara the confidence to enroll in a yoga instructor course. She experimented with asking questions on the course, focusing her attention on how people responded to her rather than on how she was feeling. The experiments helped Lara to see that people responded to her in a kind and friendly manner, and that no one judged her now or in the past, which made her feel much more comfortable in social situations.
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 133
Outcome At the end of treatment, Lara no longer suffered from PTSD, social anxiety disorder, dysthymia, or generalized anxiety disorder. She occasionally felt sad when she thought about her daughter’s early life. However, reminding herself of her daughter’s achievements and that her early life was a short period during which Lara met her basic needs with unconditional love helped her to feel more compassionate toward herself. One year after treatment ended, Lara had successfully completed an advanced yoga instructor training course. She now runs yoga retreats in Spain and Morocco.
EFFICACY AND EFFECTIVENESS OF CBT FOR PTSD Degree of Change With Treatment There is good evidence from randomized controlled trials (RCTs) that individual CBT is efficacious in reducing the severity of PTSD symptoms, with large effect sizes. For example, a meta-analysis by Watts et al. (2013) reported a large controlled effect size of g = 1.26 (g = 1 is equivalent to a symptom change of 1 standard deviation) for pre- to posttreatment changes with CBT across 54 trials with 2585 clients. Analyses of subsets of CBT programs showed mean effect sizes of 1.63 for programs primarily focusing on cognitive interventions, 1.08 for those using primarily exposure, and 1.36 for those using both exposure and cognitive interventions. EMDR (Shapiro, 1989) also showed a large effect size of g = 1.01. EMDR has overlapping elements with TF-CBT in that it includes series of brief 30 sec exposures to images of the trauma while clients focus on an external stimulus, typically therapist-directed lateral eye movement, and identifies alternative positive beliefs to replace negative beliefs. Comparison of Outcomes for Different Treatments According to meta-analyses, trauma-focused treatments are more efficacious than other psychological treatments such as stress management, supportive therapy, or hypnotherapy (e.g., Cloitre, 2009; Tran & Gregor, 2016; Watts et al., 2013). NICE (2018) found a substantially better outcome (effect size SMS = 1.64 for self-reported PTSD symptoms and 1.35 for blind assessments) for TF-CBT programs compared with wait lists. Across trials of clients with single event and multiple traumas, 60% of clients no longer had PTSD at the end of TF-CBT. Non-trauma-focused CBT also led to greater changes in PTSD symptoms than wait lists, but with smaller effect sizes than TF-CBT (SMS = 0.93 for self-reported PTSD symptoms and 0.59 for blind assessments). TF-CBT was superior to supportive counseling (SMS = 0.58 for self-reported PTSD symptoms and 1.04 for blind assessments) and present-centered therapy, which focuses on the client’s current problems rather than the trauma (SMS = 1.29 for self-reported PTSD symptoms and 0.65 for blind assessments).

Long-Term Outcomes Studies of the long-term effects of TF-CBT programs have also shown encouraging results. A meta-analysis of 32 studies with 72 treatment conditions by Kline et al. (2018) suggested that all active treatments showed long-term efficacy and advantage over control conditions, which were maintained throughout follow-up. Nevertheless, more data on long-term outcomes are needed (Bisson et al., 2013). Treatment Acceptability In addition to the efficacy, the acceptability of treatments is an important clinical criterion in the evaluation of treatments. Overall, trauma-focused treatments are associated with somewhat greater dropout rates than non-traumafocused treatments. Compared with the mean dropout rate of 13% for all psychological treatments, TF-CBT programs showed mean dropout rates of 23% in RCTs (Bisson et al., 2013). While dropouts cannot be unambiguously interpreted as a sign of poor treatment response, data suggest that dropouts have poorer outcomes than completers (e.g., Ehlers et al., 2013). Thus, while TF-CBT programs were highly efficacious, a significant proportion of clients did not complete the treatment protocol and are thus likely not to have received the full benefits. These data suggest that client engagement needs careful attention in TF-CBT. However, there is heterogeneity in dropout rates across TF-CBT studies, which may be a function of client group, therapist experience with the treatment model, and/or treatment protocol. For example, Schnurr et al. (2007) observed a greater dropout rate of 38% for PE in an RCT of women veterans or active duty staff than most other RCTs of PE, and the authors point out that the chronicity of the sample, broad inclusion criteria, and use of nonexpert therapists may have contributed to greater dropout rates and smaller within-group improvements. CT-PTSD has been shown to have a very low dropout rate (3% on average) in several RCTs in adults (Ehlers et al., 2003, 2005, 2014; Ehlers, Wild, et al., 2020) and children (Meiser-Stedman et al., 2017; Smith et al., 2007). Three effectiveness studies (Duffy et al., 2007; Ehlers et al., 2013; Ehlers, Grey, et al., 2020) in routine clinical services showed higher dropout rates (around 15%) than the RCTs of CT-PTSD, but rates were still below the average for RCTs of TF-CBT of 23% (Bisson et al., 2013). In women who had been sexually abused during childhood, Cloitre et al. (2010) found that training in affect regulation and interpersonal skills decreased dropout rates in PE compared with supportive counseling followed by PE (15% versus 33%). However, there was no comparison group that started PE immediately. Treatment Guidelines On the basis of these results, international treatment guidelines recommend trauma-focused treatments as first-line psychological treatments for PTSD (e.g.,
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 135
American Psychological Association, 2017; Australian Centre for Posttraumatic Mental Health, 2007; International Society for Traumatic Stress Studies, 2019; NICE, 2018; Stein et al., 2009; U.S. Department of Veterans Affairs & Department of Defense, 2017). Some of the recent guidelines recommend non-traumafocused CBT programs (such as present-centered therapy or stress inoculation training) or pharmacotherapy as second-line treatments (International Society for Traumatic Stress Studies, 2019; NICE, 2018; U.S. Department of Veterans Affairs & Department of Defense, 2017).
Effectiveness Studies Stewart and Chambless (2009) reviewed effectiveness studies of anxiety disorders in clinical practice, including six studies of PTSD, and found that the outcomes in clinical settings were in the same range as those in efficacy RCTs. There was a small inverse relationship between clinical representativeness of the samples and outcome (i.e., there was some loss in effectiveness in clinically representative samples). Some RCTs were conducted in clinical settings and found comparable outcomes to RCTs in academic settings (e.g., Foa et al., 2005, PE; Neuner et al., 2008, NET). Similarly, outreach programs after the Omagh and London bombings (Brewin et al., 2010; Gillespie et al., 2002) found similarly large effects for CT-PTSD on PTSD symptoms as those observed in RCTs (intent-to-treat pre-posttreatment effect sizes of around 2.5; Ehlers et al., 2003, 2005, 2014; Ehlers, Wild, et al., 2020; Meiser-Stedman et al., 2017; Smith et al., 2007) with over 70% of the clients remitting from PTSD. Three further effectiveness studies (Duffy et al., 2007; Ehlers et al., 2013; Ehlers, Grey, et al., 2020) implemented CT-PTSD in routine clinical services. The samples treated in these studies included a wide range of clients including those with complicating factors such as severe social problems, ongoing objective danger, very severe depression, borderline personality disorder, or multiple traumatic events and losses. Therapists included trainees and experienced therapists. Outcomes remained very good, with large intent-to-treat effect sizes of 1.25 and above. Around 60% of the clients who started therapy remitted from PTSD. These results, and those of Schnurr et al. (2007) and Steenkamp et al. (2015) for PE and CPT, are in line with Stewart and Chambless’s conclusion that there is some loss of effectiveness in clinically representative samples compared with RCTs. The reasons remain unclear and require further investigation. They could include client factors (e.g., chronicity, comorbidity, attitude to treatment), therapist factors (e.g., experience with PTSD treatment, commitment to trauma-focus of the intervention), quality of treatment delivery, social factors (e.g., financial problems, stability of living situation, ongoing threat), and organizational factors (e.g., limits to number or length of sessions in the service). It is noteworthy that the clients in the effectiveness studies did not receive more sessions on average despite the complexity of their problems. There was also evidence that the treatment for clients with multiple traumas and social problems was less trauma-focused than for other clients in the same cohort (Ehlers
136 Ehlers and Wild
et al., 2013). Thus, the dose of trauma-focused work they received may have been less than ideal. Does TF-CBT Make Some Clients Worse? Clinicians are sometimes concerned that focusing on trauma memories in TF-CBT may risk making their clients worse. However, the empirical data suggest that TF-CBT is safe. The percentage of clients whose symptoms worsened with TF-PTSD in RCTs was close to zero, and smaller than in clients waiting for treatment (Ehlers et al., 2014; Jayawickreme et al., 2014). Similarly, studies of clients treated in routine clinical care also showed that hardly any clients experienced a mild degree of symptom worsening over a course of TF-CBT (e.g., 1.2% in Ehlers et al., 2013), and it remains unclear whether this was due to treatment or new life events/stressors. Different Modes of Treatment Delivery TF-CBT is usually delivered once or twice a week, but other delivery formats have also been found to be efficacious. For example, CT-PTSD has been successfully used in an intensive format, where therapy is delivered daily over the course of 5 to 7 working days (Ehlers et al., 2014; Murray et al., 2017), and in a briefer self-study assisted16 format (Ehlers, Wild, et al., 2020). PE has also been found to be efficacious in an intensive format (Foa et al., 2018, Hendriks et al., 2018). Web-based interventions (e.g., Knaevelsrud & Maercker, 2007; Lange et al., 2003; Litz et al., 2007; Wild et al., 2016) have also shown encouraging results. Virtual reality is promising tool for exposure therapy (Rothbaum et al., 2001). Comparisons of CBT With Medication There is evidence that pharmacological treatment with antidepressants, especially SSRIs, has small to moderate effects in PTSD. For example, the meta-analysis by Watts et al. (2013) reports a controlled effect size of g = 0.48 for SSRIs, and that by NICE (2018) reports placebo-controlled effect sizes of SMS= 0.26 for self-reported PTSD symptoms, and 0.28 for blind assessments. The improvement observed with TF-CBT is greater than that observed with medication, and the combination of TF-CBT with medication yields better outcomes than medication alone (e.g., NICE, 2018). However, there is no evidence that the combination of TF-CBT with medication leads to better outcomes in PTSD than TF-CBT alone (e.g., Hetrick et al., 2010; Rauch et al., 2019). Zoellner et al.’s (2019) RCT found that PE was superior to sertraline on most outcome measures. In addition, client preference was an important factor in treatment outcomes in that participants who were assigned to their treatment of choice had better compliance and better outcomes.

MECHANISMS OF CHANGE Excessively negative appraisals about what the trauma and its aftermath mean about the self or other people are addressed directly or indirectly in most forms of TF-CBT. A review of 65 treatment studies (Brown et al., 2018) found that psychological treatments lead to changes in both PTSD symptoms and negative posttrauma appraisals, and that the degree of change in symptoms and appraisals is correlated. They identified 15 studies that investigated whether cognitive change during treatment drives symptom change, or vice versa. Eleven of these studies supported cognitive mediation of symptom change, in that change in negative posttrauma appraisals predicted subsequent change in PTSD symptoms, but not vice versa. For example, Kleim et al. (2013) used bivariate growth curve modeling of session-to-session measures of unhelpful appraisals (as measured by a short version of the PTCI; Foa et al., 1999) and PTSD symptoms in a sample of 268 clients treated with CT-PTSD. In line with cognitive theories, decreases in the PTCI predicted subsequent symptom change in the following session, whereas there was no significant effect of symptom improvement on subsequent change in appraisals. One study reviewed by Brown et al. (2018) showed the opposite pattern of prediction (reverse mediation), and three studies supported both mediation and reverse mediation. Thus, change in problematic posttrauma appraisals appears to be a mechanism common to effective trauma-focused psychological treatments. Wiedemann et al. (2020) replicated Kleim et al.’s (2013) results in a second consecutive cohort of clients treated with CT-PTSD and also investigated whether the results extend to the other factors proposed in Ehlers and Clark’s (2000) model: qualities of memories and maintaining behaviors such as safety behaviors, rumination, numbing and thought suppression. The results also supported these factors as mediators of symptom change.
APPLICATIONS TO DIVERSE POPULATIONS TF-CBT has been shown to be effective in the treatment of PTSD following a wide range of traumas. There has been debate about whether people who suffered prolonged or multiple traumas or those whose traumas happened in childhood need different interventions than those with PTSD following discrete events in adulthood. However, a meta-analysis of RCTs (Ehring et al., 2014) showed the same pattern of results for adult survivors of childhood abuse with PTSD as other meta-analyses of PTSD treatments: trauma-focused psychological treatments were more efficacious than non-trauma-focused treatments. TF-CBT programs led to large improvements in PTSD symptoms (Hedges’s g = 1.34). Similarly, several RCTs showed large effect sizes for outcomes for refugees who had experienced multiple traumatic events (e.g., Neuner et al., 2008). A meta-analysis (Thompson et al., 2018) supported the use of individual traumafocused psychological interventions such as NET and EMDR in this population, with a mean effect size of SMD = 1.14 compared with inactive controls.
138 Ehlers and Wild
There is, however, evidence to suggest that veterans or military populations may benefit less from psychological and pharmacological treatment for PTSD than civilians (Watts et al., 2013; Steenkamp et al., 2015). A meta-analysis of RCTs by Steenkamp et al. (2015) reported that while the first-line psychological treatments CPT and PE led to moderate-to-large improvements in PTSD symptoms (d = 0.78–1.10) in this population, only 28 to 40% recovered from PTSD. The benefits of these treatments compared with non-trauma-focused treatments such as present-centered therapy were also less pronounced than in studies with civilians (see also Foa et al., 2018; Schnurr et al., 2007). TF-CBT programs have been successfully adapted for children and adolescents (e.g., Cohen et al., 2018; Foa et al., 2008; Smith et al., 2009). One of the common adaptations concerns the education of parents about the child’s PTSD and how they can support their child through treatment. A meta-analysis by Gutermann et al. (2016) concluded that there is good evidence that a range of TF-CBT programs, especially when conducted in individual treatment with the inclusion of parents, are highly effective for trauma symptoms (see also Gillies et al., 2012; NICE, 2018). Long-term follow-ups indicated the maintenance of treatment effects (Gutermann et al., 2017). When treating clients from a different cultural background to that of the therapist, therapists need to be aware of culture-specific beliefs and may need to adapt some of the treatment procedures accordingly. For example, Schnyder et al. (2016) discuss that survivors may be exposed to (self-)stigma in the aftermath of trauma as result of culture-specific meanings linked to trauma and trauma-related disorders. This may make them reluctant to talk about their traumatic experiences. In treatment, they may instead be willing to write or use other ways of accessing the painful memories such as drawing. Community and family cohesion are especially important for recovery in some cultures. The authors point out that while awareness of culture-specific aspects is important, premature cultural stereotyping is unhelpful, and the general principles of TF-CBT are applicable across cultures.
DISSEMINATION TF-CBT programs have been successfully disseminated into clinical services and to other countries. PE is the most widely disseminated TF-CBT program to date (Foa et al., 2013). However, dissemination programs of TF-CBT have difficulties and obstacles to overcome, and some decreases in overall effectiveness have been observed under some conditions. In an early attempt to disseminate TF-CBT, Clark and colleagues trained local clinicians who did not have experience with treating PTSD in CT-PTSD after the Omagh bomb in Northern Ireland, using a workshop followed by subsequent case supervision. This training enabled the clinicians to achieve similarly good outcomes with their clients as those observed in RCTs of CT-PTSD (Gillespie et al., 2002). Similarly, Foa et al. (2005) successfully trained community therapists working at a rape crisis center in PE through workshops and
Cognitive Behavior Therapies for Posttraumatic Stress Disorder 139
weekly supervision and found that the community therapists achieved the same outcomes with PE as therapists from Foa’s academic center. These studies show that it is possible to train therapists who are inexperienced with PTSD and TF-CBT programs through workshops and case supervision. Weekly measures of PTSD symptoms were important in the training effort, as they are not only helpful in monitoring the effects of the intervention, but also in convincing clinicians who were skeptical about a trauma-focused approach of its benefits in leading to fast improvement (Clark, 2018; Foa et al., 2013). Foa et al. (2013) discussed the successes and challenges encountered in the dissemination of PE, including the adaptations to other cultures. They highlight the importance of the quality of training (which requires case supervision of at least a few training cases besides a manual and workshop), high-level organizational support, and an appropriate infrastructure for the maintenance of dissemination efforts. In the United States, both PE and CPT have been disseminated into the Veterans Administration health care system through a large training initiative (Karlin et al., 2010). The National Child Traumatic Stress Network (https://www.nctsn.org) aims to make Cohen et al.’s (2018) TF-CBT program more available for young people with PTSD. NET has been successfully disseminated in Uganda through the training of lay counselors (Ertl et al., 2011; Neuner et al., 2008). In the English National Health Service, TF-CBT has been disseminated into the Improving Access to Psychological Therapies (IAPT) program. This program aims to implement empirically supported psychological treatments for depression and anxiety disorders including PTSD. It established a new work force by training over 10,500 new psychological therapists and deploying them in new services. IAPT treats over 560,000 clients per year, obtaining clinical outcome data on 98.5% of these individuals, and places this information in the public domain. Around 50% of clients treated in IAPT services recover, and two-thirds show clinically worthwhile benefits (Clark, 2018). Schnyder et al. (2016) and Foa et al. (2013) pointed out that when disseminating empirically supported psychotherapies for PTSD across cultures, limited resources and a poor health infrastructure in many low and middle income countries pose a challenge. Possible solutions include training lay therapists from the community (e.g., Neuner et al., 2008) and web-based interventions or telemedicine (e.g., Knaevelsrud & Maercker, 2007; Lange et al., 2003; Litz et al., 2007; Wild et al., 2016). Therapists attitudes such as skepticism toward evidence-based interventions and overestimation of the risks of exposure to trauma memories can also impede the implementation of TF-CBT (Foa et al., 2013; Schumacher et al., 2018).
CONCLUSIONS AND FUTURE DIRECTIONS Knowledge about the best ways to treat PTSD has rapidly accumulated over the last decades, and a range of TF-CBT programs have been shown to be
140 Ehlers and Wild
efficacious and effective and are now recommended as first-line treatments in international treatment guidelines. The majority of clients treated with TF-CBT programs achieve clinically significant benefits that do not only include a very large reduction in PTSD symptoms, but also improvement in comorbidity, everyday functioning, and quality of life. Nevertheless, it remains an important challenge for future studies to determine why some clients or groups of clients achieve little or smaller benefits, and why there is a certain loss of treatment effects in effectiveness studies. Studies of mediators and moderators of treatment effects are likely to help with further development of treatment strategies and techniques for those who achieve suboptimal outcomes, and they may help develop criteria for individual decision making on which treatment to offer. There are aspects of treatment delivery that require further research. For example, the recent revision of the International Classification of Diseases (ICD-11; World Health Organization, 2018) distinguishes between PTSD and complex PTSD. While the treatment programs reviewed in this chapter were designed for a wide range of presentations, including those that meet the ICD-11 complex PTSD criteria, further investigation is needed to determine whether additional treatment techniques are helpful and if phased interventions have benefits or disadvantages. NICE (2018) also recommends studies of stepped care and sequencing of treatment. Access to TF-CBT in the community is still limited due to the high prevalence of PTSD and a lack of trained therapists. The dissemination of these effective treatments therefore remains a challenge, and the best way to train large numbers of therapists in delivering one of the effective TF-CBT programs needs to be studied further. The current evidence shows that a combination of workshops, treatment manuals, and case supervision are required to train therapists to a sufficient standard of competence. It is likely that online training materials will increasingly play an important role in dissemination efforts. Similarly, technological tools such as online therapy or virtual reality have shown promising initial results and have the potential to greatly improve access to treatment such that systematic evaluations are warranted.

5 Eating Disorders Madelyn Ruggieri, Courtney McCuen-Wurst, and Kelly C. Allison

ognitive behavioral therapy (CBT), as applied to eating disorders, is based on Beck et al.’s (1979) conceptualization of CBT as “an active, directive, time limited, structured approach used to treat a variety of psychiatric disorders” (p. 3). Just a couple of years later, Fairburn (1981) adapted the approach for the treatment of bulimia nervosa (BN), and later for binge-eating disorder (BED; Fairburn et al., 1993). The core of this treatment has endured as the front-line approach for BN and BED. Arguably, anorexia nervosa (AN) has been the subject of more popular interest than BN and BED, and the focus of its treatment was originally psychodynamic (Bruch, 1970). CBT is also now a recommended treatment for AN in adults, but the evidence for its efficacy for this disorder, as we review later in the chapter, is inconsistent.1 BN is characterized by repeated episodes of consuming objectively large amounts of food within a limited time frame paired with feeling a loss of control. Additionally, the use of compensatory behaviors intended to prevent weight gain, such as laxative use, self-induced vomiting, and compulsive exercise are employed (Lampard & Sharbanee, 2015). BN was first clinically described as we currently recognize it in 1979 by British psychiatrist Gerald Russell. Dr. Russell was treating patients with AN when he began seeing patients with “powerful and irresistible urges to overeat” in addition to an extreme fear of becoming fat (Castillo & Weiselberg, 2017, p. 85). Dr. Russell categorized these particular patients as being in a “chronic phase of anorexia nervosa” with a poorer prognosis, more resistance to treatment, and dangerous Clinical examples are disguised to protect patient confidentiality.

physical comorbidities (Castillo & Weiselberg, 2017, p. 85). Dr. Russell later retracted this statement, stating that individuals diagnosed with BN had a more favorable prognosis compared with individuals with AN. He also recognized BN and AN as separate eating disorders (Castillo & Weiselberg, 2017). The lifetime prevalence of BN is 0.28%, with an estimate of 0.5% in women and 0.15% in men, using the DSM-5 criteria among a nationally representative sample in the United States (Udo & Grilo, 2018). By comparison, the lifetime prevalence of AN is 0.8% overall, with 1.4% among women and 0.1% among men (Udo & Grilo, 2018). Purging disorder is similar to BN, except that the meals prompting the inappropriate compensatory behaviors are not “objectively large.” Instead, persons with purging disorder vomit, use laxatives, or use diuretics after eating a meal or a snack (Keel, 2007). These behaviors are still quite serious, even without including the objectively large amount of food in the criterion. The prevalence of purging disorder is estimated between 1.1% to 5.3% among women, with no estimates among men (Keel, 2007). Development of treatments are still underway for purging disorder, so the same CBT approach for BN that is discussed below is typically applied. BED is also characterized by recurrent episodes of consuming an objectively large amount of food in a short period of time paired with a feeling of loss of control. During binge episodes of overeating, individuals often eat much more rapidly than normal, eat until uncomfortably full, consume a large amount of food even when not physically hungry, eat alone due to embarrassment related to the amount of food consumed, and feel disgusted, depressed, or guilty after these episodes. However, unlike those with BN, those with BED do not use compensatory behaviors (American Psychiatric Association [APA], 2013). BED was first identified by Dr. Albert Stunkard (1959), who later worked with others to establish the first diagnostic criteria for the disorder (Spitzer et al., 1993). Although the disorder was previously identified as an “Eating Disorder Not Otherwise Specified,” it was characterized as its own disorder in the DSM-5 in 2013 (APA, 2013). AN is characterized by extreme food restriction that leads to a significantly low body weight. Typically, persons with AN develop very strict rules about what, when, and how much of any specific food they allow themselves to consume. There is no specific diagnostic cutoff for body mass index (BMI) or percent of expected weight in the DSM-5 criteria, but mild AN would be specified by a BMI of 17.00 kg/m2 or higher, moderate would be 16.00–16.99 kg/m2, severe would be 15.00–15.99 kg/m2, and extreme would be a BMI below 15 kg/m2 (APA, 2013). For an individual who is 5 ft 5 in., this would translate into weights of ≥ 103 lb for mild, between 96 and 102 lb for moderate, between 90 and 95 lb for severe, and ≤ 89 lb for extreme. Individuals with AN have a strong fear of weight gain or becoming fat. They also place a very high value on their shape and weight for self-evaluation, accompanied by very little insight into their actual shape and size and the seriousness of their low weight as it relates to their medical, psychological, and social well-being. There is a restrict-
Eating Disorders 151
ing type and a binge-purge type, where persons restrict most of the time but also have periodic binge-purge episodes. If all the criteria for AN are met, a diagnosis of AN will override a diagnosis of BN, BED, or purging disorder. Night-eating syndrome (NES) consists of a delayed pattern of eating, such that individuals consume at least 25% of their intake after the evening meal, and/or they wake during the night to eat at least twice per week (Allison, Lundgren, O’Reardon, et al., 2010). Persons with NES are aware of their nighttime eating; if they are sleepwalking and eating or have very limited awareness, it would be considered sleep-related eating disorder (SRED), which is a parasomnia (American Academy of Sleep Medicine, 2014). The diagnostic criteria indicate three of the following features should also be present: (a) lack of appetite in the morning/skipping breakfast more than half the time; (b) a strong desire to eat between dinner and bedtime; (c) initial onset or middle insomnia at least half the time; (d) the belief that one must eat to fall (back) asleep; and (e) low mood or worsening mood as the day progresses. Distress regarding this behavior should also be present. Although NES can be diagnosed comorbidly with the other eating disorders, careful consideration of other primary causes should be determined, such as medications (i.e., sleep agents such as zolpidem) or other causes of insomnia. Prevalence of NES is estimated at 4.6% in men and 3.4% in women among participants in the Swedish Twin Registry (Tholin et al., 2009), and 3.8% of men and 4.3% of women among a U.S. university sample (Runfola et al., 2014).
BULIMIA NERVOSA Underlying Theory We start with BN because its treatment serves as the foundation of CBT for all of the eating disorders. The cognitive behavioral theory posits that the core psychopathology of BN is related to overvaluation of shape and weight, or judging one’s self-worth mostly by weight and body shape, thus ignoring perceived performance in other domains of life (Cooper & Fairburn, 2011; DuBois et al., 2017). In turn, overvaluation of shape and weight can result in dietary restraint and restriction, body checking, and preoccupation with thoughts about shape and weight (Cooper & Fairburn, 2011). Individuals with BN tend to marginalize other areas of their lives due to this focus, which becomes a losing proposition given that controlling one’s weight and shape completely is difficult, if not impossible, thus maintaining low self-esteem. This overly dependent self-evaluation based on shape and weight leads to the behaviors that characterize BN (Murphy et al., 2010). One aspect of BN that is not directly related to overvaluation of shape and weight is binge eating. The cognitive behavioral theory posits that binge eating occurs in response to attempts to adhere to extreme dietary rules. Breaking these rules strengthens patients’ beliefs that they lack self-control, which maintains the core features of the psychopathology (Fairburn et al., 2008; Murphy et al., 2010). Binge episodes often occur in response to negative mood states
152 Ruggieri, McCuen-Wurst, and Allison
and act as a temporary mood neutralizer. This response can result in habitual binge-eating when negative mood states are present (Fairburn, 2002). BN often goes unnoticed, as individuals with the disorder are at or above the normal weight range. In addition, those with the disorder often do not have medical complaints that would warrant visiting a physician (Castillo & Weiselberg, 2017). When individuals do seek treatment for the disorder, the literature shows that the treatment of choice for BN is CBT (Cooper & Fairburn, 2011). CBT-BN is utilized with individuals who can be treated on an outpatient basis. Treatment typically lasts up to 20 sessions, with maintenance or booster sessions following less frequently, as needed. With some individuals, progress is limited by maintenance factors associated with the core psychopathology of BN, including clinical perfectionism and low self-esteem (Fairburn, 2002), which are discussed below. Main Procedures Treatment is relatively short term (about 20 sessions delivered over 16 weeks on average, with some variability) and is based on a structured manual to be led by a trained clinician. Treatment can be divided into several stages, as described by Fairburn et al. (2008). Stage one involves establishing a therapeutic relationship, as well as the introduction of self-monitoring. Detailed logs of all food and beverages consumed, accompanied by associated thoughts and feelings are established in this first stage. Psychoeducation on the ill effects of rigid dieting and purging behaviors is provided, and implementation of a more regular eating pattern and healthy food choices are also introduced. Ideas about healthy shape and weight are discussed, and weekly weighing is established. The first several sessions are delivered twice per week to establish momentum. Stage two aims to help individuals deal with the dysfunctional thoughts and triggers that drive their dieting behaviors, such as rigid rules around food that lead to binge eating. The cognitions typically addressed are targeted to (a) create insight into the impact of overvaluation of weight and shape and its consequences, (b) develop other aspects central to one’s self-concept, (c) challenge body-checking and feelings of “fatness,” (d) examine etiological factors for overvaluation, and (e) develop skills to address eating disordered attitudes and thoughts. During stage three, progress is reviewed, and realistic planning for the future is discussed (Fairburn, 1995). These final sessions may be delivered every other week. More recently, an updated form of CBT has been developed called enhanced CBT (CBT-E). CBT-E was developed in response to the finding that many eating disorders have similar core psychopathology (Fairburn et al., 2003), and thus a more inclusive treatment was developed to treat all eating disorders using a “transdiagnostic approach” (Fairburn et al., 2008). The CBT-E model suggests that the core psychopathology of BN may be maintained by (a) mood intolerance, (b) clinical perfectionism, (c) low self-esteem, and/or (d) interpersonal problems. In the first model, the impulse to binge and purge is due to mood
Eating Disorders 153
intolerance; binge eating and purging functions to regulate emotions. Clinical perfectionism refers to striving toward extremely high standards in every domain of one’s life. The term “clinical” refers to perfectionism becoming problematic when attempts to pursue these high standards continue despite negative consequences. Perfectionistic standards with regard to weight and shape would then lead to disordered eating. Core low self-esteem refers to an insidious negative view of self-worth. In the CBT-E model of treatment for BN, core low self-esteem differs from low self-esteem in that it is unconditional, which is more pervasive as opposed to being situational or limited in scope. Individuals with BN characterized by core low self-esteem are not affected by changes or improvements in the state of the disorder, as they believe these eating patterns are part of their identity (Cooper & Fairburn, 2011). In other words, core low self-esteem contributes to hopelessness about one’s ability to change, which may negatively affect treatment. Interpersonal problems contribute to core low self-esteem while creating negative mood states, leading to binge eating and purging behaviors (Lampard & Sharbanee, 2015). Cooper and Fairburn (2010) stated that most patients will benefit from the original CBT for BN approach, but for those presenting with more complex pathology, initiating the broadened treatment is useful. Efficacy Research on the effects of CBT-BN indicates that half the patients make a full and lasting recovery, with the most significant effect being the reduction of the frequency of binge episodes and compensatory behaviors (Fairburn, 2002; Fairburn et al., 2008). In a systematic, quantitative review of psychotherapy for BN, Hay et al. (2009) identified CBT as significantly superior to no treatment or wait-list control for the proportion of patients in remission from binge eating, RR = 0.69, 95% CI [0.61, 0.79]. When compared with other psychotherapies, including hypnotherapy and psychoanalytic or psychodynamic therapy, CBT has been shown to be more efficacious in the treatment of BN symptoms, RR = 0.83, 95% CI [0.71, 0.97]. CBT was also superior to no treatment or wait-list control in reducing depressive symptoms, SMD = –0.69, 95% CI [–1.09, 0.30], whereas it was favored, but not statistically significant, over the previously listed psychotherapies in reducing depressive symptoms, SMD = –0.28, 95% CI [–0.57, 0.00]. CBT-E therapy is considered “enhanced” because, as mentioned above, it incorporates strategies to improve outcomes associated with hindrances to change, including mood intolerance, clinical perfectionism, low self-esteem and interpersonal problems, in addition to focusing on overvaluation of shape and weight (Murphy et al., 2010). In a trial conducted by Fairburn et al. (2009), 154 participants were enrolled in a two-site randomized controlled trial (RCT) involving 20 weeks of treatment and a 60-week follow-up period. The two forms of treatment were enhanced, with the “focused” approach targeting disordered eating psychopathology exclusively, and the “broad” version targeting
154 Ruggieri, McCuen-Wurst, and Allison
one or more of the associated problems, in addition to the core psychopathology. Participants in the control condition had an 8-week waiting period prior to treatment. Results were based on global EDE change and showed that patients in the wait-list control group demonstrated little change in symptom severity (–0.09), whereas those in the active conditions (focused and broad) displayed significant and equal change in symptom severity (–1.51 vs. –1.53, respectively); this change was maintained during follow-up. One form of therapy that has been used as a comparator for CBT is interpersonal psychotherapy (IPT). IPT is an evidence-based psychotherapy for disorders in which interpersonal difficulties are maintaining factors. With regard to eating disorders, patients can become more isolated from their peers due to their eating disordered attitudes and behaviors, resulting in psychopathology that persists because it goes unnoticed. In addition, interpersonal problems can exacerbate or cause low self-esteem, which tends to increase efforts to control shape and weight (Murphy et al., 2012). IPT can be used as an alternative to CBT-BN, but treatment often lasts longer (approximately 8–12 months longer), and treatment responses tend to be slower in the beginning, but similar over longer follow-up periods (Fairburn et al., 2008). In a study conducted by Agras et al. (2000), 220 patients meeting criteria for BN were randomized to 19 sessions of either CBT or IPT and evaluated for 1 year after treatment. Results indicated that CBT was significantly superior to IPT at treatment end for the proportion of individuals recovered (29% vs. 6%) and remitted (48% vs. 28%). For treatment completers, the proportion recovered was 45% in CBT versus 8% in IPT. However, at the 1-year followup, there were no significant differences between the CBT and IPT treatment completers. Special Considerations With This Population CBT-BN has been tested in adolescents and adults. There do not seem to be any contraindications for its use based on gender or race/ethnicity. As noted above, if certain core psychopathologies are present, the broad version of CBT-E should be employed (NICE, 2017). Mechanisms of Change In the original CBT-BN model, changes in overvaluation of shape and weight and dietary restraint are the two most important mechanisms of change (Lampard & Sharbanee, 2015). Studies have shown that changes in these two factors relate to changes in BN symptoms, such as reductions in binge eating and compensatory behaviors. CBT-E utilizes different modules that are meant to treat different maintaining factors of BN, in addition to treatment of the core psychopathology. For example, the mood intolerance module is intended to lead to changes in mood, which will then lead to reductions in binge eating (Lampard & Sharbanee, 2015). Peterson et al. (2017) showed that improvement in emo-
Eating Disorders 155
tion regulation, or the ability to tolerate momentary negative mood states and self-directed behavior from baseline to midtreatment and to posttreatment follow-up, predicted improvements in global eating disorder scores. Application to Diverse Populations Statistics on the prevalence of eating disorders in minority populations are scarce. This may be due to a historically biased view that only White women suffer from eating disorders or that few studies have been conducted with significant numbers of people from varying racial and ethnic groups and men (Ham et al., 2015). Following completion of diagnostic interviews by a national representative sample of adults in the United States, Udo and Grilo (2018) reported that, on the basis of DSM-5 criteria, the lifetime prevalence for BN was 0.28%. Prevalence of any eating disorder was greater for women than for men after adjusting for various demographic variables including age and race and/or ethnicity. Adjusted odds ratios did not differ significantly by race and/or ethnicity for BN. The same study examined these differences for AN, showing significantly lower adjusted odds ratios for non-Hispanic Black (AOR = 0.48, 95% CI [0.33, 0.72]) and Hispanic (AOR = 0.19, 95% CI [0.11, 0.33]) respondents than for non-Hispanic White respondents. Finally, for BED, Udo and Grilo (2018) reported lower lifetime (AOR = 0.60, 95% CI [0.38, 0.92]), but not 12-month, adjusted odds ratios for non-Hispanic Black compared with non-Hispanic White individuals. Case Example “Erica” reported starting to binge and purge with vomiting during her freshman year of high school. She was attending a high-pressure private school that she found challenging, but she was supported by her family, and she was particularly close with her father. Tragically, her father died in an accident, and she was having trouble coping. She started to eat emotionally, and she started gaining weight. After eating sweets in the evening, she would try to restrict what she ate the next morning, fearing she would continue gaining weight. She was active as a soccer player, and she also enjoyed running in the off season. Over her high school years, her binge-and-purge episodes continued, but she was able to hide them. She presented for treatment her senior year in college, afraid that she would continue this pattern even after she graduated. It had started to sink in that this was not just a temporary fix but a cycle that had taken on a life of its own. Erica described experiencing stress related to her coursework and her relationships with her mother and her peers. By now, her mother knew of Erica’s disordered eating, but she was uncertain how to address it. They bickered over concerns for Erica’s well-being and the financial burden the binge episodes were causing. Erica’s mood was also affected by these binge-purge episodes, which negatively influenced her body image further. This led to trying on
156 Ruggieri, McCuen-Wurst, and Allison
outfits for up to an hour before going out with friends or avoiding social events altogether. Finally, with school, if she felt overwhelmed by starting a project or studying for an exam, she would be triggered to binge, followed by vomiting. She would then feel ill and end up watching shows or movies in her room by herself, leading to missed deadlines and poor grades. Therapy began with a log of her eating and purging behaviors to identify her pattern of eating and the triggers for her binge episodes. Erica identified several episodes from the previous week. The therapist spent time reviewing a particular episode with her that involved baking brownies for a fundraiser for her club soccer team (see Figure 5.1). She also felt overwhelmed because she had a paper due the next day and did not know where to start. She began eating the brownies and was unable to stop, finishing the whole pan. She felt disgusted and overly full, but she thought it would be okay because she could get rid of the calories and the feeling of being too full if she just vomited. Afterward, she was exhausted and shut herself in her room to watch shows the rest of the night. She felt sad and ashamed the next morning when she had to ask her professor for an extension for her paper. First, psychoeducation was provided regarding the limited effectiveness of purging to compensate for the calories consumed. Next, the therapist used a thought record to help her identify the situation—having a paper due, but not knowing where to begin. Next, she identified her feelings, which included feeling anxious, overwhelmed, and tired, as well as her automatic thoughts. These thoughts included, “I can’t come up with a good idea for how to start my paper. Whatever I write, it won’t be good enough,” and, “The brownies look so good, it will be okay if I just eat one.” After not being able to stop and eating the pan of brownies, she identified these thoughts: “I feel disgusting. If I just throw up, I will feel better and will be able to get on with my night.” After vomiting she FIGURE 5.1. Food Intake and Binge/Compensatory Behavior Log Time Location 12:00 pm

I was stressed about writing a paper and had just made the brownies for my club’s fundraiser. I wanted to just eat one, but I couldn’t stop. I felt so full that I had to make myself vomit. Then I was relieved, but exhausted. I didn’t feel up to doing any schoolwork.

stated, “I am worn out and can’t concentrate. I don’t feel better and don’t feel up to writing.” The therapist helped Erica identify alternative responses to each thought, also asking her to recognize and tolerate her negative emotions. For example, although she was feeling anxious about writing, her homework for the coming week was to open a document and start typing her ideas out, no matter how tired or overwhelmed she felt. She believed that once she was sitting and writing, she would be able to complete the assignment, so she agreed to this homework task. Erica was also having trouble resisting vomiting after normal meals given the frequency of her episodes. She stated that even any “normal” sized meal made her feel uncomfortable. The therapist used exposure exercises to have her sit after meals and engage in conversation or go somewhere where she was unable to purge to prevent compensation from occurring. Finally, the therapist helped her use these tools to address her body image issues and improve communications with her mother around her eating and weight concerns so that Erica’s need to be secretive about it would lessen and she could start to rebuild her relationship with her mother. A joint session was held to help facilitate communication between Erica and her mother, as well. As sessions progressed, Erica was able to show good understanding and use of the CBT skills, decreasing her binging and purging episodes over time. She was still having periodic episodes in response to stressors or when home alone with access to baked goods or granola bars (two of her most difficult trigger foods), but she was pleased with her progress and felt more confident about graduating and moving into an “adult life” without the burden of BN. She felt more confident in her body as well, as she generally felt more in control and less depressed. She had even begun dating a fellow student as the sessions concluded.
BINGE-EATING DISORDER Underlying Theory Theories of the psychopathology of BED are based on cognitive behavioral theory and the restraint model (Grilo, 2017). According to cognitive behavioral theory, BED, similar to the models for AN and BN, can be characterized by an excessive attention to weight and shape, a desire for control associated with eating behavior, and/or emotional dysregulation (Fairburn, 2017; Haedt-Matt & Keel, 2011; Haedt-Matt et al., 2014; Wilfley et al., 2000). Although overvaluation of weight and shape is not included as a diagnostic criterion for BED, its presence typically indicates a more severe form of the disorder (Mitchison et al., 2018). Additionally, there are particular cognitive and behavioral differences observed in those with BED that are not observed in those with AN nor BN. Wilfley et al. (2000) found that individuals with BED have significantly lower cognitive restraint of eating (i.e. deliberately restricting food in an effort to align with rigid rules regarding eating) scores compared with those with AN and BN. Further, persons with BED are more likely to report eating in secret,
158 Ruggieri, McCuen-Wurst, and Allison
being unsatisfied with their weight, feeling fat, being unhappy with their shape, and experiencing discomfort with seeing their body compared with individuals with AN, BN, and persons who have overweight or obesity but who have no eating disorder. Compared with those with AN and BN, people with BED do not have a significant desire to have a completely flat stomach and report less distress and less avoidance of eating (Wilfley et al., 2000). Whereas the cognitive behavioral theory of binge eating suggests that thoughts and feelings about body shape and size and other emotional distress become triggers for binge episodes, the restraint theory suggests that dieting increases the likelihood of binge eating. As a result of a calorie deficit, either through dieting or skipping meals, hunger levels increase, leading to a sense of loss of control once eating is allowed. The more frequently this restriction occurs, followed by a binge episode, the more likely it is for a cyclical pattern to develop (Polivy & Herman, 1985). However, not all persons with BED have a history of restriction. Thus, binge eating could also result as a means of controlling or distracting oneself from experiencing emotional dysregulation. Main Procedures CBT for binge eating focuses on the cognitive distortions often exhibited in those with eating disorders (Fairburn, 2017), such as concerns about shape and weight, “all or nothing” thinking, perfectionism, and low self-esteem. Given the influence that weight and shape have on the way individuals with BED view themselves, treatment focuses on improving self-confidence and discovering alternative influences on self-worth other than weight and shape. Treatment also focuses on creating more regular healthy eating habits and identifying and resolving triggers associated with maladaptive eating patterns. CBT for binge eating was adapted from CBT-BN (Fairburn et al., 2008), as described previously. As with any manualized form of treatment, it is important to follow the protocol for optimal effectiveness. A meta-analysis by Vocks et al. (2010) examining various forms of treatment for binge eating found CBT-based psychotherapy and structured self-help to have a strong effect on reduction in binge eating. Evidence suggests that following a structured program may be a useful first-line approach to treating BED, and also that using a self-help approach based on the manual holds promise and may also increase access to CBT care (Grilo, 2017). Special Considerations With This Population A majority of those with BED have other psychiatric and medical comorbidities, independent of weight status (Kessler et al., 2013). There is a strong evidence base of a high comorbidity rate between psychological disorders and BED, with the most common disorders being mood, anxiety, and substance use disorders. Additionally, BED is associated with medical comorbidities, such as dyslipidemia and Type 2 diabetes; however, the evidence is not as consistent for
Eating Disorders 159
medical as for the psychopathology comorbidities (Devlin, 2017). Although comorbidities are important to consider when conceptualizing a clinical case, they do not necessarily have an effect on treatment outcomes (Kessler et al., 2013), as discussed in the section on mechanisms of change. As with the other eating disorders, individuals with BED often have complex presentations, with binge eating representing only one of many health concerns. Efficacy CBT is considered the leading psychological approach to treatment for eating disorders by both the American Psychiatric Association (Yager et al., 2012) and the National Institute for Health and Care Excellence (NICE, 2017), with CBT for BED proven efficacious in eliminating binge episodes in about 60% of those who receive treatment (Fairburn, 2017). In addition, CBT for BED has been shown to reduce eating-disorder-related psychopathology, including depression. CBT for BED has largely been proven superior against controls such as medications and behavioral weight loss in binge eating outcomes. It is important to note that while CBT for BED is efficacious in improving the aforementioned symptoms, it is not particularly helpful for weight loss (Grilo, 2017). A meta-analysis by Vocks et al. (2010) that included 1,973 participants found CBT more efficacious in reducing binge-eating frequency (d = 0.82, 95% CI [0.41, 1.22]) and days with binge eating (d = 1.04, 95% CI [0.70, 1.38]), as well as increasing binge-eating abstinence (d = 6.83, 95% CI [3.50, 13.33]) compared with untreated control groups. CBT also was found to reduce binge-eating-related psychopathology such as depression (d = 0.36, 95% CI [0.08, 0.64]), to a lesser degree, and concerns about weight (d = 0.85, 95% CI [0.43, 1.27]) and eating (d = 1.43, 95% CI [0.84, 2.01]). CBT for BED did not significantly reduce dietary restraint scores, shape concern, or body mass as compared with those without treatment. Vocks et al. (2010) also found that self-help CBT significantly reduced binge frequency (d = 0.84, 95% CI [0.37, 1.30]) and concerns with weight (d = 0.85, 95% CI [0.43, 1.27]) and eating (d = 1.43, 95% CI [0.84, 2.01]), while increasing binge abstinence (d = 25.77, 95% CI [9.74, 68.15]). Additional improvements observed with self-help CBT include decreased dietary restraint scores (d = 0.68, 95% CI [0.09, 1.26]) and concerns associated with shape (d = 0.66, 95% CI [0.25, 1.07]); however, this self-help form of therapy did not significantly reduce depressive symptoms. Brownley et al.’s (2016) systematic review and meta-analysis found therapist-led and structured self-help CBT for BED more efficacious in decreasing binge frequency and increasing binge-eating abstinence compared with wait-list controls (58.8% vs. 11.2%, RR = 4.95, 95% CI [3.06, 8.00]). Therapistled CBT also significantly reduced global eating disordered attitudes and behaviors (strength of evidence, moderate; no relative risk reported), but not depressive symptoms or body mass. Multiple studies have found no to minimal effect of combining medication with CBT compared with CBT alone for the treatment of BED (Devlin et al., 2005).
160 Ruggieri, McCuen-Wurst, and Allison
Mechanisms of Change Although CBT for BED has been established as one of the leading treatments for binge eating, there is a paucity of literature on mechanisms of change. Grilo et al. (2012) examined moderators and predictors of response to CBT treatment. They found the most predictive and moderating trait of binge eating remission in CBT treatment was the overvaluation of shape/weight, whereby those who had lower scores of overvaluation of shape/weight were more successful at treatment end. Several demographic variables, including education status and older age of onset of the disorder, were associated with higher rates of binge remission. However, Grilo et al. (2012) found that psychiatric disorders, personality disorders, and obesity failed to predict or moderate BED treatment outcomes. Medical comorbidities, which are also often found among those with BED, have not been examined as predictors of treatment efficacy. A systematic review by Vall and Wade (2015) examining predictors of efficacy among various BED treatments found several significant factors. First, higher weight suppression (i.e., the difference between an individual’s highest weight and current weight) was associated with more binge episodes. Second, more frequent binge eating at baseline predicted worse binge-eating outcomes at end of treatment. Third, higher motivation to change and less eating disorder pathology predicted better outcomes. Finally, several psychopathology measures at baseline predicted better outcomes, including lower depressive symptom scores, higher BMI, higher self-esteem, lower weight/shape concerns, older age of onset, shorter duration of the disorder, less comorbid psychopathology, and better interpersonal functioning. It is important to note that while the majority of studies examined in this systematic review included forms of CBT, the authors did not exclusively examine CBT, including other forms of treatment as well. Kober and Boswell (2018) argued that neural processing features and certain areas of the brain, such as the ventral striatum, amygdala, insula, and orbitofrontal cortex (Boswell & Kober, 2016), now often measured in brain imaging studies, may also provide insight into treatment outcomes. They offer that impairments in cognitive control and increased emotional reactivity, food-cue reactivity, and cravings are likely related to emotion dysregulation, which in turn may cue binge eating. However, more research is needed to pair outcomes with imaging studies to outcomes in CBT trials for BED. Application to Diverse Populations A randomized placebo-controlled trial by Grilo et al. (2014) evaluated the effectiveness of a weight-loss medication (sibutramine) and a self-help form of CBT, alone and in combination, in an ethnically diverse primary care setting (55% non-White) for the treatment of BED. Although sibutramine was associated with greater weight loss compared with placebo, none of the treatments differed in binge-eating outcomes. Demographic factors, such as age, sex, race, and education, did not predict any changes in outcomes. It appears that CBT for
Eating Disorders 161
binge eating is equally effective across different demographics, but more studies would be valuable to confirm these results. Clinical Example “John” is a 40-year-old African American man with a BMI of 42.1 kg/m2 (5 ft 8 in., 285 lb) who meets the criteria for BED. He works as a delivery person for a local paper product manufacturer whose primary clients are various restaurants in the area. Each day while making deliveries, he is offered food (e.g., pizza, sandwiches, baked goods, etc.; see Figure 5.2). John usually skips breakfast to control his weight. He often packs what is considered a normal sized lunch, such as a turkey and cheese sandwich, small bag of chips, a granola bar, and soda, but he typically eats it around 10:00 a.m., well before he originally intended. Later on, he continues to snack on the foods offered to him from various restaurants. For example, he may eat a slice of pizza around 11:30 a.m., then a side of French fries and large (12 in.) cheese steak around 1:00 p.m. This pattern continues throughout the day. John finishes his shift around 4:00 p.m. and has dinner with his wife and two children at their home around 5:45 p.m. However, about twice per week, John will stop, without his wife knowing, at his favorite Italian chain FIGURE 5.2. Example of Behavioral Chain for Binge-Eating Disorder
162 Ruggieri, McCuen-Wurst, and Allison
restaurant for an all-you-can eat dinner after 4:00 p.m. During these occasions, he eats about five breadsticks, three large bowls of salad, and two large pasta entrees. Once he begins eating, he reports feeling immense pleasure and inability to stop. He orders the second pasta and tells himself that he will buy it now but save it for his lunch tomorrow. However, once the food arrives, he always ends up eating that portion before he leaves. He keeps these episodes from his wife, using cash instead of charging the meal. This routine has become a secretive, affair-like relationship with food. When he returns home and eats dinner with his family, he has a regular plate of food (i.e., two grilled chicken breasts, one cup of macaroni and cheese, and a baked potato). Often, he will follow dinner with dessert, such as two ice cream bars or a one-eighth portion of pie, from about 5:45 p.m. to 6:00 p.m. He reports having his restaurant meal before his “actual dinner” because he is embarrassed about overeating in front of his family. This way, he can enjoy his large meal by himself without the shame and guilt he experiences from eating large amounts in front of others. Although John feels pleasure while eating, he feels guilty and disgusted afterward, and his eating is negatively impacting his relationship with his family. John has experienced nine binge episodes per week, on average, for the past 2 years. In treatment, the therapist began by reviewing the CBT model for the treatment of BED. The therapist reviewed a food log form to track his intake throughout the day, including when, what, and how much he was eating, and what triggers may have been present before eating. Next, they completed a behavioral chain to make the chain of events explicit. Completing these exercises increased his awareness regarding his belief that restricting in the morning would be healthy, but in fact, it was prompting him to eat his lunch early, producing dichotomous thinking that he had ruined his plan for the day, so he might as well eat the food that was offered to him at the restaurants. He was assigned to begin eating a nutritionally sound breakfast and continuing to pack his lunch and snacks. Dysfunctional thought records were introduced next to modify these automatic thoughts, including the opportunity to generate alternative responses he could use in those situations. Each week, he completed these tools to provide opportunities during each therapy session to use each difficult eating situation as a learning tool, and to illustrate progress when he successfully resisted loss-of-control eating episodes. As he progressed through treatment, he gained momentum by internalizing his successes and building self-efficacy for his ability to decline food offers from the restaurants. The therapist also helped John focus on alternative activities he could do after work when he was feeling compelled to stop at the restaurant. This intervention included planning a different route home so he would avoid driving near the restaurant and setting up an exercise routine for himself with his children or his wife, when possible, during that time instead. He also generated other ideas for filling that time, like accomplishing household tasks that had been lingering or starting a hobby that he had not participated in for a while. The final target of treatment included targeting his body dissatisfaction. Following the use of Socratic questioning (i.e., asking key questions to draw out
Eating Disorders 163
answers to the patient’s own questions and to uncover assumptions that may be the basis for one’s automatic thoughts), John was able to describe the pressure he was feeling from his wife and his own standards to preserve a muscular physique that he had when he was several years younger. He viewed himself as a failure with his 30-pound weight gain over the previous 2 years, and he was developing health issues, such as high blood pressure and hyperlipidemia. The therapist used thought records to help John modify his discomfort with his body, as well as emphasize healthy eating habits and physical activity that would help to address his growing health concerns. Finally, marital issues that contributed to his secretive, disordered eating behaviors were addressed, and the therapist assigned John exercises to talk with his wife regarding the impact of her language regarding health behaviors and body shape and size expectations on his emotional and physical functioning. A typical thought was “My wife won’t know that I ate it, so I might as well have it now so that I don’t overeat in front of her and risk having her comment about it.” An alternative thought that he eventually generated was “Just because my wife doesn’t know, doesn’t mean that I don’t end up feeling badly about it. I will feel better if I say no now, and I will not feel like I’m hiding things from her and my kids.” John found success by instituting a regular eating schedule and by typically packing his own meals and snacks. He developed the ability to decline foods that were offered to him on his deliveries, and the business owners stopped offering food so frequently as his responses remained consistent. He physically felt better and less sluggish by the end of the day, so he was more open to going home and spending time with his children and being active with them or by himself. He also felt as though a burden had been lifted between him and his wife, as he was not spending money for binge episodes and hiding his behavior. John was able to communicate more openly with his wife about comments and rules that she had regarding weight and eating that were maintaining his secretive eating behaviors, raising her awareness of the paradoxical result that her comments were having. She was able to prepare meals and snacks that provided more satiety for John, and to support his packing and preparing of meals and snacks for work. Overall, John reduced his binge episodes to about once per month. In the final sessions, the focus was on his ability to recover from infrequent episodes and learn from the triggering event, emotion, or thought to continue preventing binge episodes from occurring most of the time.
ANOREXIA NERVOSA Underlying Theory After Fairburn adapted Beck’s CBT for depression for use with BN, others in the field (e.g., Garner & Bemis, 1982, 1985) provided a treatment manual of CBT for AN. The formulation of CBT for AN is similar to that described above for BN and BED; overvaluation of weight and shape, which are rooted in low self-esteem, lead to a strong drive or desire to control one’s weight and shape through extreme restriction of food intake. Thus, the cognitive disturbance
164 Ruggieri, McCuen-Wurst, and Allison
—extreme dissatisfaction with weight and shape—leads persons with AN to make choices to restrict their intake or compensate inappropriately after eating (the behavior). This becomes a cycle that is quite difficult to break. Persons with AN differ from those with BN and BED by their achievement of a very low body weight. To reach such a low weight, individuals typically have certain personality features, such as perfectionism, and a temperament that can sustain such self-deprivation. Their low self-esteem is often tied to feelings of social unease and ineffectiveness, and they often lack an awareness of their feelings (a lack of interoceptive awareness), such that they are unable to express their emotions constructively. They then turn their distress inward and try to put their focus on controlling their eating in order to control their weight and shape, which is conceptualized as a strong drive for thinness. AN-restricting subtype is manifested by strict restrictive behaviors, and AN-binge-purge subtype is characterized by dietary restriction most of the time, interrupted by binge-purge episodes, which also can become cyclical. Once caught in this cycle, eating causes increasing discomfort—both cognitively, with negative thoughts about one’s value as a person if they eat something “bad” or too much of a serving, and physically, with increasing gastrointestinal discomfort as weight loss and starvation become severe. Persons with AN obsess about food and planning what and how they will eat the little amount of food that they allow themselves, and their worlds generally become smaller. They isolate themselves more to focus on their food and weight goals and become less able to eat or socialize with others because of their extreme eating rules and rituals. However, they are living in a trapped world where they believe the only way they can increase their self-esteem is to control their weight and shape. Main Procedures CBT for AN consists of the same phases of treatment as described above for BN; however, the first goal of treatment for AN is always weight gain. This is so for obvious safety reasons, but also for efficacy reasons. If someone is starving, their thinking becomes increasingly rigid, and it becomes difficult to engage in talk therapy in an effective manner. Thus, in the first phase, the rationale for CBT is described, and psychoeducation is provided on the biological, psychological, and social underpinnings of the disorder. Persons with AN are often reluctant to engage in treatment, as their loved ones may be more distressed by their symptoms than they are, so an appraisal of their motivation for treatment is useful. This phase is also a time to build the therapeutic relationship by focusing on setting collaborative goals for improvements. This can be challenging for those with AN because they may not want to gain weight, but in outpatient treatment, clear goals should be set for progression of weight gain. A skilled therapist will set about this task in an empathic and open manner so that patients have a voice in expressing their goals and desires for regarding their eating disorder and their desired quality of life. The therapist can carefully highlight how the eating disorder has increasingly taken on its own life, and how it
Eating Disorders 165
initially may have felt to the patient that they were in control, but now the AN is in charge. As this conversation progresses, along with weight gain, patients can start to disengage from the AN thoughts and behaviors, and they improve their ability to express longer term goals and desires for their lives outside of weight and shape. Weight is taken at each treatment session on a regular schedule—typically at the beginning of each session. If patients are reluctant to see their weight, desensitization to seeing the number becomes part of the therapy. Homework is also an essential part of the treatment, and patients must understand from the outset that there will be goals and tasks to practice at home, such as increasing the number of meals, increasing their calories and nutrients, and decreasing physical activity, which will be reviewed and problem-solved at their next session. This homework also includes self-monitoring of all food eaten, where it is eaten, as well as details about one’s automatic thoughts and possible triggers for restricting or binge eating and purging. From these records, the therapist and patient can work together into the second phase of treatment to identify feelings, self-deprecating thoughts, and patterns of interpersonal exchanges that maintain the eating disorder. They can then work to establish alternative ways of cognitively assessing these situations so that healthier eating patterns can replace the dysfunctional ones, and skills for managing one’s feelings and interpersonal interactions can be implemented. During this phase, a weight gain goal is clarified, and a meal plan is set. Collaboration with a nutritionist and physician is recommended to implement the meal plan and weight regain goals safely. The weight goal should be a range based on past weight history before onset of AN, as well as other health parameters, such as resolution of amenorrhea, if applicable. An action plan should be developed with the patient to identify the necessary steps to increase the likelihood that the prescribed meals and snacks will be eaten. These can be used to problem-solve situations where patients are experiencing obstacles to enacting their eating plans or other homework assignments, which prevents them from reaching their goals (e.g., weight gain, improved social skills, decreased body dissatisfaction). Thought records are used in this phase to identify and restructure cognitive distortions, such as “If I eat three meals a day, I will be fat and disgusting” or “If I go out after I have eaten, my stomach will be so bloated that everyone will notice.” The content of these thoughts can relate to eating, body dissatisfaction, or everyday stressors or interpersonal problems. Modifying these thoughts and generating alternative responses is an ongoing process, with hope that the patient will continue to use this strategy even once treatment has ended. Several behaviors are targeted with thought-restructuring exercises, including body checking, which can take on the form of extended periods of time pinching oneself or scrutinizing oneself in the mirror, picking at one’s clothing so that it is not too form-fitting, and seeing if parts of one’s body are touching (e.g., thighs) or hanging (e.g., arms or stomach). Excessive exercising is also targeted, with an initial moratorium on exercise until weight has approached the desired
166 Ruggieri, McCuen-Wurst, and Allison
range. Exercise can be reintroduced at that time, with attention to rigid thoughts that sustain the excessive nature of exercise typically seen with AN. Finally, the behaviors associated with undereating, such as choosing low-fat foods, moving food around on the plate and cutting food into small pieces during the meal, and any variety of methods used to consume smaller quantities of food than prescribed, are addressed in this phase of treatment. The therapist would start with validation of how difficult it is to stop using these behaviors, followed by challenges to discontinue the use of these behaviors that maintain the psychopathology. Once patients have approached their weight goals and they are normalizing eating behaviors, the last phase of treatment shifts toward deconstructing the schema that maintain AN. Weight restoration is typically accomplished before the disordered attitudes regarding body weight and shape and low self-esteem are significantly improved. This treatment phase focuses on identifying other aspects of oneself outside of shape and weight that they value, as well as longerterm life goals and ways in which AN is not consistent with those values and goals. A visual, typically a pie chart, can be used to identify one’s current valuation of all aspects of oneself, as well as the version of the chart that one aspires to without having the AN (see Figure 5.3). Further work on interpersonal interactions and regulation of emotions is also targeted in this phase of CBT for AN, such that one can increase self-efficacy and not rely on AN symptoms as distractors from solving problems effectively in the real world. Therapy typically ends with sessions every other week to help patients practice and maintain their skills. Booster sessions may be scheduled as needed following treatment end. Efficacy Unfortunately, there have been relatively few studies of CBT for AN and limited development of the theory, perhaps because of its low prevalence and the historically high dropout rates observed in treatment (Galsworthy-Francis & Allen, 2014). In general, CBT or CBT-E for AN show significant gains in BMI, eating disordered attitudes and behaviors, and mood, but these outcomes are not typically significantly better than comparison treatments, such as IPT, family-based therapies, and specialist supportive clinical management. With CBT for AN, BMI shows increases between 0.9 to 2.1 kg/m2 (e.g., from a BMI of 16.0 to 16.9–18.1 kg/m2) from baseline to treatment end (Byrne et al., 2017; Fairburn et al., 2013; Zipfel et al., 2014). This has not been superior to the gains shown with specialist supportive clinical management, ranging from 1.4 to 1.5 kg/m2 (e.g., from a BMI of 16.0 to 16.4–16.5 kg/m2; Byrne et al., 2017; McIntosh et al., 2005; Schmidt et al., 2015), or Maudsley model anorexia nervosa treatment for adults (MANTRA), with gains ranging 1.4 to 1.8 kg/m2 (e.g., from a BMI of 16.0 to 16.4–16.8 kg/m2; Byrne et al., 2017; Schmidt et al., 2015). When examining the proportion of participants who reach a BMI of 18.5 kg/m2, CBT is not superior to other treatments statistically, but there seems
Eating Disorders 167
FIGURE 5.3. Visualization of Current Versus Desired Self-Schema in a Patient With Anorexia Nervosa
to be more separation when using this measure, with 59% in CBT-E, 44% in MANTRA, and 48% in specialist supportive clinical management reaching this marker of weight normalization (Byrne et al., 2017). In a systematic review of CBT for AN, Galsworthy-Francis and Allan (2014) included just 16 treatment studies that had been conducted between 1995 to 2014, with only five of those being RCTs. Comparison between therapies and examination of long-term outcomes was difficult, they reported, due to the high treatment dropout rates, particularly with follow-up data. Thus, no statistical comparisons across studies were reported. Galsworthy-Francis and Allan (2014) further confirmed that CBT often produced significant gains in BMI, disordered eating pathology, and some general pathology. This was not superior to results from other approaches (e.g., dietary counseling, nonspecific supportive management, IPT, behavioral family therapy), but less dropout was observed in the CBT treatment conditions in four of seven controlled studies, particularly as compared with inpatient treatment and nutritional counseling. They also suggested that one reason CBT does not perform significantly better than other approaches with AN could be that the large amount of psychoeducation and use of cognitive skills, such as thought restructuring, may be too difficult in light of the cognitive rigidity associated with starvation in this disorder. However, it appears that CBT for patients with severe and enduring AN (duration of more than 7 years) show similar outcomes as patients who do have this high level of impairment and disability (Calugi et al., 2017). Calugi et al. (2017) reported that among 66 inpatients, 44% of the nonsevere (n = 34) and 41% of the severe (n = 32) groups reached BMIs greater than 18.5 kg/m2, indicating a weight in the “normal” range, with 32% and 33%, respectively, having minimal eating disorder pathology at a 12-month follow-up. Overall, the data are not convincing that CBT for AN is superior to other treatments, but it also is not inferior to other treatments. It may be more
168 Ruggieri, McCuen-Wurst, and Allison
acceptable to patients, as evidenced by slightly lower treatment dropout rates (Galsworthy-Francis & Allan, 2014), so it certainly remains one of the best options available at this time for adults with AN. Mechanisms of Change CBT for AN first targets weight regain so that rigidity of thinking is reduced and the substance of treatment, such as modifying dysfunctional thoughts regarding overvaluation of weight and shape and extreme restraint of eating, can ensue. As specific examples of triggers and eating disordered attitudes and behaviors are modified and skills are taught for generating alternative responses, the underlying schema (i.e., one’s framework for conceptualizing oneself and one’s view of the world) of what the individual values and strives for in life can shift from control of one’s body weight and shape to more varied and productive goals. These mechanisms are hypothesized based on the cognitive theory of eating disorders (Fairburn, 2017; Fairburn et al., 2008). More data are needed to confirm these pathways. Special Considerations With This Population Outpatient care for patients presenting with very low BMI (below 17 kg/m2) would typically be contraindicated. A full assessment of medical stability and safety should be undertaken in conjunction with a physician to determine the appropriate level of care in these cases (e.g., hospitalization or partial hospitalization; NICE, 2017). Application to Diverse Populations As Galsworthy-Francis and Allan (2014) commented in their review, most studies of CBT for AN did not report race or ethnicity, let alone the impact of age, sexual orientation, or gender identity (most studies report over 90% of participants are women). It is unclear how these factors may impact CBT outcomes for AN.
NIGHT-EATING SYNDROME Underlying Theory The core feature of NES is that the typical daytime pattern of food intake is delayed, which interrupts the normal diurnal sleep-wake cycle. Persons with NES feel compelled to eat to fall asleep initially or to fall back to sleep during the night. NES is conceptualized as an eating disorder with features of sleep (insomnia) and mood (depressive) symptoms. Thus, CBT was adapted for NES based on the approaches for each of these disorders. Allison et al. (2004) described four of the most common themes reported by persons with NES before their nocturnal eating episodes. These included expe-
Eating Disorders 169
riencing (a) specific food cravings (e.g., “I know that jar of peanut butter is in the cabinet—I can’t fall back to sleep now until I have some”), (b) feeling anxious or agitated (e.g., “I am still worried about how my meeting at work will go tomorrow and can’t sleep, but if I eat, that will help me fall back to sleep”), (c) feeling the need to eat something so one’s stomach feels full (e.g., “I just need to put something in my stomach, and then I will be able to sleep”), and (d) feeling the need to eat to fall back to sleep (e.g., “I will be a wreck at work tomorrow if I don’t get back to sleep soon—I know I can fall back to sleep if I eat something, so that is what I will do”). Unfortunately, persons with NES often experience shame, disgust, and distress after nocturnal eating, particularly in the morning. Many describe feeling as though they have a “food hangover,” causing them to delay their eating in the morning, thus perpetuating the cycle. Main Procedures As with the previously described approaches, in the first stage of CBT for NES, the therapist develops the therapeutic relationship, explains the rationale for CBT, and educates the patient on the basic techniques of CBT (Allison, 2012). These techniques include monitoring sleeping, eating, and mood patterns, along with the automatic thoughts associated with these events (Sessions 1–4). The Nighttime Eating Assessment—which presents a series of visual analog scales that the patient completes before eating at night to identify mood states that might be triggering the urge to eat—are to be completed for the first 2 weeks of therapy. This exercise helps to identify other targets of therapy so that skills can be developed to undermine the patient’s typical pattern (Allison, 2012). Thought records are used to construct alternative thoughts and responses to the urge to eat at night, and the use of social support is encouraged. In addition to identifying the stressors and thoughts that precipitate unwanted eating, the patient is asked to complete food logs to detail their circadian pattern of food intake. Patients are encouraged to move their first meal of the day earlier (e.g., if nothing is eaten until 2:00 p.m., a lunch at noon would be prescribed), with successively earlier meals assigned in subsequent sessions. The therapist explains that although regulating the daytime eating schedule is not sufficient to stop the nocturnal ingestions, it is necessary to break the delayed pattern of eating. In addition, the therapist encourages behavioral experiments (i.e., homework designed to modify beliefs about the pros and cons of behaviors, and debunk dysfunctional thoughts that sustain those—usually negative—behaviors) to address the nighttime awakenings and ingestions, including attention to the energy and nutrient content of the snacks. A “kitchen is closed” time is also chosen, indicated with a verbal declaration and by turning the lights off. Patients are encouraged to brush their teeth and move to another area of the house after that time. A behavioral chain describing the specific steps in a patient’s nocturnal eating episodes, along with ways that the patient can break the links, is also completed and given to the patient for reference at home.
170 Ruggieri, McCuen-Wurst, and Allison
If patients have overweight or obesity and have a desire to lose weight, calorie tracking with their food log is instituted at Session 3, with typical goals of 1,200–1,500 calories for women and 1,500–1,800 calories for men. At weights above 250 lb (113 kg), adjustment of these calorie goals is made accordingly. Clinical experience has suggested that implementing a calorie goal improves motivation for change and therapy compliance among those seeking treatment for NES, as part of their distress regarding their nighttime eating is its negative influence on their weight gain. Restraint and overvaluation of weight and shape are not as extreme in those with NES as in BED and other eating disorders (Allison et al., 2005), so encouraging a structured behavioral weight loss component does not seem contraindicated for this disorder. In the middle stage of CBT for NES (Sessions 5–8), the work centers on firmly establishing the skills that have been developed in the first phase. Depressed mood and dysfunctional thoughts about eating continue to be monitored and addressed through the use of thought records, together with continued use of behavioral interventions. Behavioral experimentation is essential for decreasing the occurrence of evening and nighttime ingestions. Although the actual methods may differ based on the layout of the patient’s house, the presence or absence of family or roommates, and what food is available, each approach involves stimulus control of food, including strategies such as preparing preset, portion-sized snacks and placing them on the counter or in the front of the refrigerator; locking or hiding away desirable food at night; or engaging in another activity until sleepiness returns. Thoughts regarding fear of weight gain and lack of hunger with regard to starting to eat earlier in the day, and with regular daytime meals and snacks, is also addressed. If depressed mood is present, these symptoms are treated with the same thought records and behavioral activation/change of typical routine outlined previously. Negative beliefs about weight and shape, if present, are also be attended to throughout the therapeutic process, as these beliefs are often intricately tied to negative affect. The final stage of therapy, Sessions 9–10, transitions to biweekly sessions. The therapist reviews progress and helps the individual generate possible triggers for relapse. Therapists also aim to increase self-efficacy regarding the patient’s ownership of the progress they have made, so that they can maintain their progress outside of the therapeutic relationship. Efficacy One study has tested CBT for NES, with a 10-session treatment delivered over 12 weeks among 25 participants (Allison, Lundgren, Moore et al., 2010). Intention to treat analysis showed significant reductions in the percentage of food intake consumed after dinner (from 35% to 24.9%), number of weekly awakenings (from 13.5 to 8.5 per week), and weekly nocturnal ingestions (from 8.7 to 2.6 per week; Allison, Lundgren, Moore, et al., 2010). Among participants with overweight or obesity, a 3 kg weight loss was also reported, with caloric reductions from 2,356 per day at Session 3 (the first time calories are tracked)
Eating Disorders 171
to 1,759 per day at treatment end. More studies are needed to confirm these results. Mechanisms of Change CBT for NES seems to work by recalibrating an individual’s temporal pattern of eating, such that the nocturnal drive to eat, which becomes habitual over time, is diminished and patients no longer feel compelled to eat, even if they continue to wake up during the night. The treatment uncouples the urge to eat during the night from the act of falling asleep initially or falling back to sleep, so that even if they have problems initiating sleep or waking during the night, they are able to do other soothing activities in order to resume sleep (Allison, 2012). These mechanisms are based on the CBT theory of NES, so these pathways should be tested further. Special Considerations With This Population Some persons with NES report that their first moments of awareness do not occur until they are standing in front of the refrigerator, whereas others are fully aware from the moment they wake and rise from bed. Persons with reduced awareness typically are not able to identify automatic thoughts until they are about to eat or are already eating. Treatment of nocturnal ingestions focuses on increasing awareness progressively earlier in the waking process so that patients can access and implement the CBT skills during the nocturnal eating episodes. Behavioral approaches, such as placing a bell or some other type of alarm on the door may be used in some cases to raise awareness before they are even able to leave the bedroom. Persons with NES who have normal weight seem to endorse more severe symptoms; a higher proportion of their intake occurs after dinner because they seem to be restricting more during the day than persons with overweight or obesity. Persons with NES who have normal weight also report higher levels of compulsive exercise to compensate for their nocturnal ingestions. Thus, those with NES with normal weight may need to pay more attention to compensatory behaviors and fear of weight gain than those with higher weights (Allison, Lundgren, Moore, et al., 2010).
DISSEMINATION OF CBT FOR EATING DISORDERS CBT has been evaluated through numerous RCTs and is regarded as the “gold standard” treatment for BN and BED, but there remains limited access to effective, evidence-based versions of this treatment. Some barriers include the availability of resources, namely doctoral-level therapists, inadequate training for therapists, and lack of competence and consistency in adhering to the treatment protocol (Fairburn & Wilson, 2013). Therefore, efforts to address these
172 Ruggieri, McCuen-Wurst, and Allison
barriers are pivotal in the transfer from evidence-based research to clinical practice. Self-help or guided self-help using evidence-based treatment manuals are also valuable in disseminating these treatments (Peterson et al., 2009). The primary manual for self-help CBT, developed by Fairburn (2013), includes information about the disorder and manualized instructions for implementation of treatment. Given the severity of AN, professional help is typically recommended. CBT and CBT-E trainings are offered through the Centre for Research on Eating Disorders at Oxford (CREDO, https://www.credo-oxford.com), and professional conferences, such as the Academy for Eating Disorders (https://www. AEDweb.org), can be valuable tools for therapists to learn this treatment. There are few self-help CBT treatments for AN, with little outcome data currently available. Much work is needed to disseminate CBT for NES given it is not wellrecognized (Goncalves et al., 2009). A self-help book is available (Allison et al., 2004), as well as a treatment manual (Allison, 2012).
CONCLUSION AND FUTURE DIRECTIONS CBT is the first-line treatment recommended for both BN and BED. The evidence is less clear for the treatment of AN, as CBT reduces symptoms but is not superior to other therapies. Even though it is the most commonly recommended therapy for BN and BED, the proportion of those patients who enter remission with treatment typically ranges between 50% and 60%, leaving a need for other therapies, given the large minority of patients whose symptoms persist. Accessing treatment can be difficult, however, so it is important to note that self-help manuals may be helpful, particularly in milder cases of BN and BED. More work is needed to validate treatments for purging disorder and NES.

n this chapter, the term addiction, which has various definitions, will stand for the term problematic addictive behavior. Figure 6.1 presents the continuum of problematic addictive behavior. This continuum can be divided between each term in the right-hand column. Although the boundaries between each pair of categories may be fuzzy, overall the progression of categories is clear. If divided under abstinence, below that division is use. If divided under moderation, below is problematic use. If divided under subclinical (or misuse), below are diagnosable disorders. If divided under mild substance use disorder (SUD), FIGURE 6.1. The Continuum of Problematic Addictive Behavior

below is the ICD-10 code (F10.2 for alcohol dependence) for a moderate or severe disorder, and if divided under moderate SUD, below is addiction: Some clinicians will choose to use the word addiction [emphasis in the original] to describe more extreme presentations, but the word is omitted from the official DSM-5 substance use disorder diagnostic terminology because of its uncertain definition and its potentially negative connotation. (American Psychiatric Association, 2013, p. 485)1
CBT can be provided for any problematic addictive behaviors or substances. Behaviors are also termed processes or activities and include gambling, pornography, sexual activity, video gaming, shopping, and others. For ease of presentation in this chapter, alcohol use will often be the addictive behavior discussed. CBT can also be provided regardless of severity. As cases become more severe (as they move down the chart in Figure 6.1), the intensity and frequency of treatment may increase and the setting may change, but treatment itself from a psychological perspective is not fundamentally different. Treatment should be offered even if the individual has only subclinical use. Focusing on subclinical use is not a trivial matter in clinical practice because the number of individuals in this category may be larger than that of all the SUDs combined. Many of these subclinical individuals might be prevented from developing a SUD if they are willing to seek services and appropriate services are available. Figure 6.1 views addictive behavior as not necessarily problematic. Nonproblematic addictive behavior (moderation) is a type of habit that causes negligible problems but arises as problematic addictive behavior does, in response to repetitive desires. These desires in their strongest form are termed urges or craving. Craving will be the term used in this chapter for the entire continuum. If a substance or behavior is initially pleasurable to the individual, it is addictive (desirable) for that individual without necessarily leading to problematic behavior. Alcohol is unlikely to become an addictive substance for an individual who immediately gets sick from it. However, most of the substances or activities we popularly (and in the DSM) consider addictive (e.g., alcohol, caffeine, cocaine, opiates, gambling, etc.) are pleasurable to most individuals, across a wide range of doses, routes of administration, settings of use, and other variables. Repetitive craving is the basis of addictive behavior, and significant problems are the basis of problematic addictive behavior, which, if severe enough, is diagnosable. With enough repetition, any addictive behavior may become problematic, meaning that the benefits of use have become outweighed by the costs. The initial transition from beneficial to overly costly addictive behavior (i.e., moving toward the bottom of Figure 6.1) may happen slowly or quickly. An individual may fluctuate up and down Figure 6.1 indefinitely. Individuals who present for treatment have generally been toward the bottom of Figure 6.1 for long enough—with enough personally painful problems and with enough ineffective efforts at self-change—that help-seeking becomes desirable. Fortunately, most individuals move back to the top (abstinence or moderation) on their own (i.e., they resolve their problematic addictive behavior through Clinical examples are disguised to protect patient confidentiality.

natural recovery). Self-guided change has recently been suggested (Bishop, 2018) as a more descriptive term. This chapter views self-guidance as the foundation of change. CBT, or any addiction treatment, is not an example of “art perfects nature” but of “art augments nature.” Individuals unable to fully accomplish self-guided change can complete the process by participating in CBT or other treatment approaches.
HISTORY CBT, specifically for addiction, became a significant presence in the scientific literature approximately in the 1980s with the work of Abrams and Niaura (1987), Marlatt and Gordon (1985), Monti et al. (1989), and others. However, these publications often describe their foundation as social learning theory (Bandura, 1969) rather than CBT specifically, and they describe themselves as providing relapse prevention or social skills training rather than CBT. Nevertheless, these publications share with contemporary CBT for addiction an emphasis on the primary role of learning processes in the development and resolution of addiction. This emphasis diverges from the general practice of the addiction treatment industry, then and now, which emphasizes addiction as a disease with primarily biological roots. The focus of emerging CBT for addiction was on developing the psychological components of treatment, while accepting that biological and social components were significant but perhaps largely unchangeable. From the CBT perspective, a full biopsychosocial approach to addiction is needed, but one oriented toward issues the individual can actually address, which are primarily psychological. CBT, nevertheless, incorporates the biology of substance use (e.g., substances can be intoxicating, some can lead to physical dependence, response to a substance is dose-dependent) and social processes (e.g., it can be very difficult to act contrary to one’s identity group or the social demands of specific situations; when there is an attempt to restrict freedom the individual will make great effort to regain freedom). The full expression of the contemporary CBT approach (for any problem, and for addiction specifically) is founded on the fundamental human learning processes, including respondent conditioning, operant conditioning, modeling, and cognitive mediation. Respondent conditioning occurs when a stimulus that elicits an automatic response (e.g., food eliciting salivation) is paired closely in time with a neutral stimulus (e.g., a bell). With enough pairings where the bell rings and the food quickly arrives, the bell alone can elicit salivation. Operant conditioning occurs when a positive or negative experience quickly follows a specific behavior. If the experience is positive, the behavior increases; if negative, it decreases. If I earn money for a behavior it tends to increase, but if I get fined it tends to decrease. Modeling occurs when we observe someone (a model) engage in a behavior new to us and we learn about the behavior by observing it. This process is also called observational learning. Cognitive mediation occurs when the “facts” of a situation are appraised (and possibly changed
180 A. Tom Horvath
substantially) by the observer. The interpretation or behavior that follows is based on the appraisal rather than immediately on the facts. You may appraise someone’s behavior as kind, but I may appraise it as manipulative. My appraisal may be based on my experience with that person, or with others who previously engaged in that behavior, or with others whom that person reminds me of, or on other aspects of my learning history. Because we can cognitively mediate our own cognitive mediations, we can change them. Mediation of mediation is at the heart of CBT. Cognitive behavioral therapists assume that learning helpful or unlearning unhelpful behaviors involves these fundamental learning processes, that human behavior is largely learned in specific contexts, that unhelpful thoughts and beliefs can also be changed using fundamental learning processes and guided practice, and that effective treatment needs to be personalized to each individual based on adequate assessment (Rotgers, 2013).
UNDERLYING THEORY CBT, as the name implies, combines behavioral and cognitive approaches to client change. The underlying theory assumes that there have been disturbances and a lower level of adaptation to the present, in both behavior and cognitions (both thoughts and beliefs). What was adaptive in a previous context or a shorter time frame may be no longer adaptive, for instance, because the context has changed or the individual has aged and more mature behaviors are expected. In CBT for addiction, specifically, the behavior of primary concern is continuing to engage with the addictive behavior (e.g., drink alcohol, use cocaine, go to the casino). The cognition of primary concern is the belief that “I need this substance/behavior in order to accomplish my goals.” CBT, thus, has multiple foci, all in the service of resolving addictive problems: (a) reducing or ending the addictive behavior, (b) building up an alternative set of beliefs such that “I don’t need this in order to accomplish my goals,” and (c) developing skills or changing situations such that the need is met in other ways (or matured out of). Typically, the third focus requires the most therapeutic emphasis. In many cases, the third focus requires a CBT approach to another disorder—most commonly anxiety, depression, or trauma. As for behavior, cognitive behavioral therapists are open to the possibility that the client may be able to shift up the continuum (see Figure 6.1) enough to moderate stably, rather than necessarily needing to abstain. At present, there appears to be no reliable way to predict who will succeed in moderating and who will need to abstain. A difficult clinical situation arises when the client for an extended period unsuccessfully pursues moderation. In these cases, the discussion needs to reemphasize the original goal of resolving problems. A comprehensive CBT model of addiction includes a focus on proximal situational factors as well as distal background factors (Wenzel et al., 2012). Because genuine early success may result in rapid termination of treatment (e.g., “I get
Addictions 181
it, why do I need to come back?”), the clinician may not have time for a complete CBT conceptualization of the client. However, when slow or no progress is occurring, or a client has returned after a premature termination, conducting treatment with reference to a comprehensive model is invaluable. What are the typical internal or external events that occur before engagement in the addictive behavior? Proximal factors include anxiety, boredom, and tension, or being out with friends, coming home after a difficult day, or seeing a beer commercial. What positive expectancies arise? These might include “I’ll be able to cope if have a drink” or “I will enjoy myself once I have a drink.” These expectances are a type of belief because they typically are not fleeting and have often been considered at length by the client. What (fleeting) automatic thoughts then arise? These might include “Just a little one” or an image of a previous enjoyable drinking experience. What craving (desire, urge, tension) then arises? Like hunger, this craving orients someone toward the object of the craving. What “permissions” then arise? These might include “No one will find out this time” or “Screw it, it doesn’t matter anyway.” Finally, what preparatory actions does the individual engage in? These might include going to the liquor store or calling a friend to go out. Despite the proximal factors at any particular moment, drinking is not inevitable. It can be interrupted by situational changes. Perhaps a loved one calls with an urgent need for assistance, or it is suddenly raining heavily, or the client realizes they are out of cash (and they do not want to use an ATM or credit card for fear of their partner discovering the expense). Drinking can be interrupted by internal changes as well. Actually, each of the just-mentioned situational changes activate helpful beliefs or priorities: “I deeply care about this loved one, and he is more important than drinking” or “I hate going out in the rain; I don’t want more conflict about my drinking.” Sometimes these internal changes arise in a way less directly connected to external cues, such as when the client is headed out the door to drink, sees something that reminds them of someone who would be upset about their drinking, and a line of thinking results in the decision to override the craving. If craving could not be overruled, then all of us would be at the mercy of whatever desire, craving, or impulse happened to enter our minds. If a simple summary of CBT for any emotional issue or disorder is, “I am not at the mercy of thoughts that enter my mind; I can evaluate and modify them,” then a simple summary of CBT for addiction is, “I am not at the mercy of cravings that enter my mind; I can act by balancing the short-term satisfaction of using against the longer term satisfactions associated with the priorities in my life.” A fundamental challenge for all human beings is how to balance our desires for satisfaction right now with acting on longer term goals. Addiction exemplifies this challenge. In most moments, life will be better, at least for a short while, if I engage in addictive behavior (Heyman, 2009). Against that near-certain pleasure and satisfaction, I can weigh the importance of my longer term interests. Am I willing to delay the likely gratification from the “right now” activity, for the less certain but bigger gratification to be experienced later?
182 A. Tom Horvath
What can make the “right now” satisfaction even more compelling is a history of distal factors that predispose us to find intoxicated states highly desirable. These distal factors can include difficult circumstances or outright trauma growing up; dysfunctional basic beliefs about the self, others, or the future; a childhood or teenage history of observing others engage in problematic addictive behavior; and personal “success” using addictive behaviors to cope or escape (leading to positive expectancies about them). If the clinician does not have significant personal experience with problematic addictive behavior, a comparable experience may be how easy or hard it is to cut back on eating when quite hungry and when not especially hungry. Individuals with a large number of distal factors are often quite eager to escape the tension that they may live with on a daily basis. As adverse childhood experiences accumulate, addiction is a common outcome (Felitti et al., 1998). For these kinds of clients CBT for addiction will, for the most part, be focused on issues covered in the other chapters.
MAIN PROCEDURES This summary of CBT for addiction describes an ideal course of basic individual psychotherapy. The summary is intended for clinicians who are familiar with CBT or addiction, but not both. Extended presentations of CBT for addiction include Walters and Rotgers (2013), who summarized evidence-based treatments for addiction (i.e., motivational interviewing, contingency management, CBT, 12-step facilitation, couples and family approaches, and medications). Miller et al. (2011) also covered brief intervention and a wide range of broader treatment issues (including settings, treatment matching, case management, promoting adherence, coping with resistance, and ethical issues). Denning and Little (2012) focused on harm reduction, an approach that helps clients improve (i.e., move up in Figure 6.1) without necessarily reaching one of the two highest levels. Wenzel et al. (2012) presented group CBT using a cognitive therapy framework. Sobell and Sobell (2011) combined group CBT with motivational interviewing. O’Farrell and Fals-Stewart (2006) presented a couples’ approach. Smith and Meyers (2004) described an approach for working with families to motivate loved ones to enter treatment. Client workbooks may be useful for both client and clinician; options include Epstein and McCrady (2009), Horvath (2004), and Monti et al. (2002). In addition to gaining current knowledge about CBT for addiction, the clinician will also benefit from an increased capacity to understand addictive experiences. The clinician may not be “in recovery”; even if the clinician has past addictive problems, about half of similar individuals do not use the term “in recovery” to describe themselves (Kelly et al., 2017). Regardless of whether this term is used, the clinician’s self-assessment about where on Figure 6.1 they
Addictions 183
have been for various substances and activities at different times in life, and in particular, any current struggles with keeping addictive behavior from becoming problematic, increases the capacity for empathic understanding of clients (Horvath, 1994). Many clinicians ignore addiction in their clients or actively attempt to avoid it. However, in most clinical settings, addiction is likely to be a component of many cases. Addiction issues (from subclinical ones to severe SUD; see Figure 6.1), like depressive symptoms, anxiety symptoms, “stress,” and relationship problems, are expectable aspects of clinical practice. Further, many clients with addiction do not identify it along with other presenting problems, or they may actively hide it. The clinician needs to screen for addiction initially, be alert for signs of it later, and be confident that providing basic addiction treatment is within their skill set. Clients are poorly served if the clinician immediately refers them out because “I don’t treat addiction.” For many clients, attending a first session is a major step forward. Facing the unknown again with a new provider may require more courage than many clients can muster. The moment of motivation, which can fluctuate rapidly with any clinical problem but especially addiction, needs to be acted upon quickly when it appears. Fortunately, basic addiction treatment is not difficult for someone already trained in CBT, and it is, similarly, not impossibly challenging for clinicians using other therapeutic approaches. There remains the option to refer the client at any time for more intensive treatment. Furthermore, addiction is remarkable in that the intensity of effective treatment is not highly correlated with the level of addiction. Clients with a severe SUD may be effectively treated with a brief course of basic treatment or even a brief intervention. For instance, in Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity), four sessions of motivational interviewing were as effective as 12 sessions of CBT or 12-step facilitation (Project MATCH Research Group, 1997). Clinicians can use the concepts and techniques from this chapter knowing that in general they will do no harm, and that they often may be sufficient to address the addiction presented, with no further treatment needed. Viewing addiction treatment in this way is to view it, as already noted, as an adjunct to self-guided change, the process by which most individuals resolve addiction. The clinician strives to identify what has halted self-guided change and assists the client in creating plans for getting beyond these obstacles. Although the addiction treatment industry generally appears to view treatment as essential to change, this perspective is not consistent with the self-empowering stance of CBT. In CBT, we help clients resolve current problems and prepare for future problems. We do not insist that everyone has the same needs; hence, we do not provide addiction “programs.” We do not provide more help than is needed; hence, clients are free to end treatment when it has served them sufficiently (and are free to return as needed). If treatment can be helpful, too much or a nonindividualized approach could also be harmful.

Treatment primarily addresses the dysfunctional belief “I need this [addiction].” Treatment also addresses beliefs like “I’m defective” (and the sense of shame, guilt, and demoralization) and “I will never have other sources of satisfaction” (and the sense of hopelessness and despair). Most addiction clients have attempted to cut back or stop. If unable to do so, they typically draw negative conclusions about themselves and their futures, and these beliefs need to be addressed. Addiction clients often expect to be criticized and labeled (e.g., “alcoholic”), and they may be highly sensitive to this possibility. The clinician can frame addictive problems as arising from a combination of factors including chance and situation (e.g., “Your first friends in college happened to be drinkers, so as a shy person of course you wanted to fit in and used drinking to do it”) and difficultly with balancing short-term and longer term satisfaction. Addiction is viewed not as a unique problem for that individual, but as an apparently universal human challenge. Just as engineers translate the findings of theoretical and applied physicists into actual products and processes, clinicians translate the findings of psychological scientists for the benefit of specific clients. In so doing they need to be aware of the differences between subjects in clinical studies and clients in actual clinical practice. This distinction exists for any disorder, but it is especially important in addiction treatment. Resolving problematic addictive behavior is fundamentally about establishing and maintaining motivation. When motivation is high enough, treatment is not needed. Clients come to treatment when they are ambivalent about change, or they would have changed already (Miller & Rollnick, 2013). They are motivated enough to seek initial consultation, but perhaps not much more. Subjects in clinical studies are highly selected and well-prepared for the treatment they experience. Subjects typically do not begin treatment until a significant degree of assessment has occurred. The assessment process may also include significant socialization about how to be a successful client. Subjects have also screened themselves as generally appropriate for the treatment they expect to experience. By comparison, many clinical practices will initially screen and evaluate nearly anyone. Because a very wide range of clients can show up, screening, assessment, socialization, treatment planning, relationship building, history taking, and other tasks all need to occur in the initial session, or there is little hope of keeping the client engaged for additional sessions. Subjects in treatment studies may often be motivated by the opportunity to receive free treatment. In return for having no financial burden, these subjects may be fairly tolerant of the study process established by scientific investigators (which may appear to have little connection to their immediate needs). Clients in clinical practice may be significantly more demanding. They want to feel respected and understood, to focus on the issues of concern to them (not to the clinician), and to have a therapist who seems sensible to them and who uses methods that make sense to them. Overall, they want to experience good value for their time
Addictions 185
and money (Norcross & Lambert, 2011). Consequently, I focus first on the initial session, in the hopes of engaging clients effectively so that they will return for additional sessions if needed. Fortunately, CBT begins even in the initial session by establishing a foundation for identifying and changing the fundamental dysfunctional belief, “I need this [addiction].” The Initial Session If the client has not volunteered information about addiction, it is necessary to screen for it. In some clinical situations, screening is accomplished by having the client complete screening instruments prior to the session. The clinician can review the responses with the client, paying particular attention to the nonverbal behavior in that discussion. If there are no screening instruments, then “What problems do you have from substance use or other addictive behaviors like gambling and video games?” is a straightforward question, but one that may not gather the information the clinician needs to be helpful. Shame, guilt, and demoralization about the possibility of change may often lead clients to withhold information about addiction, even if they have other primary presenting problems. An alternative screening question is “What substances and activities do you enjoy?” A noncommittal response can lead to an elaborated question, such as, “I’m thinking about caffeine, nicotine, alcohol, cannabis, cocaine, heroin, methamphetamine, and other substances, and activities like gambling, pornography, video games, shopping, and so forth. Which ones of these do you enjoy?” If the process of answering this question reveals client hesitation, the therapist can address this hesitation directly. Options include questions like “Is this an uncomfortable question to answer? Are you concerned that I will criticize your choices? Are you concerned about what I will do with that information?” The following statements may be useful: “You told me about your (depression, anxiety, stress, relationship) problems. Sometimes problematic addictive behavior contributes to these problems. Because we want to find a complete solution for you, it is important I understand the big picture of your life. There may be connections between your various behaviors that you didn’t realize. Fortunately, I will make almost no demands on you. Even if we do discuss changing some of your addictive behaviors, the choice to do so, or not, will be yours. In any event, all of us at times act on our short-term interests when we would do better to give more attention to our longer term interests. There are not too many people who save too much for retirement! We are all by nature drawn to short-term satisfaction. We can focus on helping you adjust that balance so that your longer term satisfactions get the attention they need.” If the client screens positive for addiction, there is probably insufficient time in the initial session for a complete functional analysis (described more fully later in this chapter). However, a limited functional analysis can be achieved by asking, “What do you like about drinking?” This question suggests that the
186 A. Tom Horvath
therapist will focus on drinking as an adaptive effort that has significant positive results for the client (or the client would have stopped it). Individuals do not continue with addictive behaviors they do not enjoy or that do not bring some benefit. Only enjoyable behaviors (e.g., drinking, gambling) are engaged in long enough, and large enough, doses to become coping methods. Ultimately these behaviors lead to the belief that “I need this” in order to cope with problems or achieve goals. In these initial interventions we are beginning to identify this client belief. The answers to “What do you like about it?” are often straightforward and easy to understand: “It helps me relax. I can’t socialize without it. I can unwind after a bad day at work with it. It makes me more creative. It gives me energy. It allows me to fit in.” The clinician can acknowledge (e.g., “That makes sense!”) how the client has, indeed, benefited from drinking. Drinking initially provides the kinds of benefits just described, but it may become problematic over time as harmful side effects occur. Additionally, the original benefits may diminish, sometimes substantially. The session now needs to transition to asking about what problems may have arisen from drinking: “So alcohol helps you relax, and you appreciate that relaxation very much. Alcohol has been a good friend in this way, and perhaps other ways as well. I’m curious though, has alcohol also led to any noteworthy problems?” Whatever problems are reported should be responded to empathically: “That’s too bad. That was hard on you. You didn’t realize that would happen and be so upsetting.” It is now time for a summary statement, such as “To summarize our discussion, you experience [these benefits] from drinking, and you don’t like [these side effects]. Have I summarized accurately?” The client may agree and spontaneously draw a conclusion, such as “I need to think about my drinking more. It’s time to cut back on alcohol” or “It’s time to stop drinking.” If such a conclusion is not offered, the client can be asked, “Given this complex relationship with alcohol, what is your plan with it?” If the session is primarily devoted to drinking (perhaps because it was the presenting problem), then treatment planning might begin immediately. If there are other more significant problems to address, then addressing drinking may be deferred: “It appears we should move on from drinking for now. If you track your drinking until next session, even if just mentally, we can discuss it again next time.” Self-monitoring is a way for the client to keep concerns about drinking in mind. Most problems need continued attention for resolution. The exact placement of the client on the continuum of problems (see Figure 6.1) is not generally a crucial issue. If there are more addictive problems than the client wants, then treatment is warranted from the clinical perspective, even if the problems do not meet medical necessity as an insurer might define it. Ideally, five accomplishments emerge from the initial session. First, the client and therapist construct a prioritized list of mutually agreed upon goals (based on “What’s wrong?”) and a tentative plan for achieving them (i.e., “How
Addictions 187
do we fix it?”). In CBT, this list and plan is often termed a case conceptualization. Second, the session needs to establish for the client that the therapist is understanding and not punitive or critical. Perhaps the therapist is helpful in articulating the client’s experience, even beyond what the client was able to express. The session also needs to establish, third, that the therapist is working on the client’s behalf (and is concerned about the client); fourth, that the therapist is respectful; and fifth, that the therapist is trustworthy. If these conditions are met, then the client can conclude that the sessions are helpful and worth a return visit (Norcross & Lambert, 2011). If the client is well advanced in self-guided change, the initial session may be the only one needed. The elements addressed in the next section may then need to be included, very briefly, in the initial session. Continued Sessions If resolving addiction is on the goal list, how much therapy time it merits will depend on the other goals being addressed. The idea that addiction is a “primary problem” and must be addressed before other problems, even if accurate in a few cases, may not align with the client’s priorities. In such cases, making progress on other goals may keep the client involved long enough to allow returning to goals about addiction. In general, from the client’s perspective, treatment involves building and maintaining motivation to change, learning how to cope with craving and manage high-risk situations, addressing related issues (e.g., anxiety, depression, trauma), achieving greater lifestyle balance (to prevent a recurrence of problems), improving relationships, and enhancing meaning and purpose in life. From the psychotherapist’s perspective, there are potentially numerous technical questions to address, including level of care, frequency and intensity of treatment, ancillary services, how to conduct exposure sessions (for coping with craving), psychiatric and addiction medications, treatment techniques for various comorbid problems, involvement of family members, harm reduction techniques, attendance in mutual help groups, communication with other providers, and so forth. An addiction specialist may well be needed, as someone to refer to or as a consultant. Nevertheless, because addiction treatment is an adjunct to a naturally occurring process, these technical questions may never emerge or may evaporate quickly. As with many activities in life (such as chess and psychotherapy), beginnings and endings are easier to describe than “the middle game.” The following tasks are presented for consideration when progress does not occur or seems to reverse itself. In longer term cases, progress is rarely smooth, and fluctuations should be expected. Cycling back to tasks that once appeared completed is common. After each recurrence, for instance, the immediate intervention can be, “What did you like about it?” Trust is also not an all-or-nothing matter. It may take some time for the client to reveal information that is crucial to success, but that the client was not ready to utter.
188 A. Tom Horvath
Time on task is also very much affected by client sophistication, resources, and circumstances. As already noted, because the client’s motivation to change is the single most important aspect of achieving a good addiction outcome, if that motivation becomes strong and stays strong, many aspects of a “complete” CBT for addiction can be abbreviated. Progress made on co-occurring problems can also be highly motivating because the belief “I need this addictive behavior” can become less accurate as alternative coping methods are developed. If the addictive behavior is needed less, addictive problems become more prominent and further increase motivation to change. As with other CBT, sessions need to be structured (to a degree consistent with client preference) to include items like a check-in about events since the last session (especially cravings and high-risk situations), an update on projects from last session and any ongoing projects, an agenda for the working time of the immediate session, plans for continuing work between sessions, and a review of progress to date on the goal list and of the session just conducted. Some clients are highly talkative, and the clinician may need to guide discussion discreetly toward the above topics, possibly in random order, rather than follow a stated session agenda. Functional Analysis A functional analysis connects the antecedents of a behavior, the behavior itself, and the consequences of the behavior (ABC) in an effort to understand how specific situations lead the client to expect that the addictive behavior will be reinforced in them. Most addictive behaviors are strongly reinforcing because of their biochemistry, and they often come to be strongly associated over time with multiple situations. Nicotine in cigarettes is a clear example of the power of learning in addiction. Although nicotine itself is a relatively weak intoxicant (i.e., no one is advised not to drive or not to sign a contract while under the influence of nicotine), it can become associated with so many situations (at least before the advent of significant smoking restrictions) that quitting can be a challenge nearly everywhere. One of the advantages of “going off to rehab” is that it removes the client from cues to use, such that abstinence in a facility is much easier to maintain than in the normal environment. Unfortunately, recurrence of addiction upon discharge is common because typically clients in residential treatment do not engage in any exposure therapy to practice facing, resisting, and forming new associations with cues to use. The limited functional analysis suggested above, to ask about the benefits (i.e., rewards or consequences) of the addictive behavior, recognizes that the biochemical effects may be more important to understand than the cues that elicit the behavior, especially if the behavior is daily or near daily. In some cases the cue is a time of day, regardless of immediate environment. A complete functional analysis (Smith & Meyers, 2004) includes antecedents such as (a) external triggers (i.e., with whom, where, when) and (b) internal triggers (i.e., what were you thinking and feeling), the behavior itself (i.e.,
Addictions 189
what, how much, over how long), and consequences such as (a) short-term positives (i.e., enjoyment with whom, where, when, pleasant thoughts, pleasant feelings) and (b) long-term negatives (i.e., interpersonal, physical, emotional, legal, vocational, financial, and other). A blank form to facilitate functional analysis may be brought into session. An easy-to-recall version of the ABC is to use the journalism questions (i.e., who, what, when, where, why, and how) with respect to relevant antecedents, behavior, and consequences, with particular emphasis on thoughts and feelings at each step. In some cases, the answer to the question “What do you like about it?” will be sufficient as a functional analysis. If an immediate reduction in addictive behavior occurs, therapeutic time may be best employed in other areas. Presumably, in these cases, treatment will focus on building the client’s capacity to achieve the benefits of the addictive behavior by other means or reducing the need for these benefits. To whatever extent the functional analysis is completed, it is used for making changes that will reduce the addictive behavior. Examples include “Oh, I get it. I have been drinking to relax. I just need new ways to relax” or “I see that most of my excessive drinking occurs on the weekends, with only two people, and only if we are watching sports. It’s so obvious when you put it down on paper. Maybe I can change that routine to help me reduce drinking until I’m strong enough to handle those situations.” Moderation Training In CBT for addiction, either abstinence or moderation is an option and can be considered from both the behavioral and cognitive aspect of CBT. The behavior may be reduced or stopped. The cognition “I need this” can become modified either to “I enjoy this but don’t need it” or “I can live without this.” In the addiction treatment industry, it is still commonplace to hear “moderation isn’t possible.” Even if moderation after severe SUD is viewed as impossible, there should be little argument that moderation after subclinical use is possible. A review of the evidence about who can most easily moderate is beyond the scope of this chapter, but a CBT perspective assumes that moderation is possible starting from any category in Figure 6.1 (Heather & Robertson, 1983; Rotgers, 2013). In practice, the more important questions are (a) how much effort will be involved in accomplishing moderation and (b) whether the benefits of moderation will have been worth the effort. Even if someone appears not to be a good candidate for moderation, it is crucial not to dictate abstinence or moderation to the client. Doing so may arouse psychological reactance (Brehm & Brehm, 1981). The result can be a client focusing on “I need to show you I can moderate” rather than focusing on “I actually don’t need this addictive behavior.” With respect to this issue, CBT adopts the perspective of motivational interviewing, meaning that the cognitive behavioral practitioner views this decision as belonging to the client. At present, the most sensible course regarding abstinence or moderation appears to be to suggest to the client that moderation is indeed possible, but
190 A. Tom Horvath
that it may not be worth the effort involved for the minor benefit likely to be obtained and at the costs likely to be experienced in what may be a trial-and-error process of successive approximation to the desired goal. If the client is already close to further major negative consequences, moderation plans need to be considered carefully. Relevant questions include ones about motivation, past history of moderation success, past history of persistence in the face of obstacles, current circumstances and the likelihood of strong cravings being elicited in them, whether the substance or behavior is illegal, and the likely reactions of significant others to moderation and to any slips or relapses that occur (Horvath, 2004). A family session on this subject may be worthwhile. In most cases, abstinence is easier to accomplish than moderation. Once use begins, it can become very difficult to maintain the belief that “I don’t need this.” Even if someone aims to moderate, an initial abstinence period of 30 or even 90 days helps fortify a full set of adaptive beliefs. Abstinence is generally easier because after about 90 days craving has often diminished to near zero, multiple social encounters have been negotiated without using, and new relevant habits have been established. A difficult clinical scenario emerges when the client is “working” on moderation but repeatedly not achieving it. In such cases, it is crucial to evaluate, via functional analysis, the episodes of excess. If the client wishes to continue in treatment, the focus may shift from moderation training to harm reduction. Client workbooks specific to alcohol moderation training include Miller and Munoz (2004) and Rotgers et al. (2002). Moderation training for other substances is even more controversial in the addiction treatment industry than it is for alcohol, but the same general approach applies. In the case of other substances, such treatment might be termed harm reduction rather than moderation training. Co-Occurring Problems Does the goal list accurately represent what the client needs to work on? Here, input from the clinician to educate the client about problematic addictive behavior, and about cognitive behavioral case conceptualization, is essential (Beck et al., 1993). Ideally, the goal list includes both new behaviors and new beliefs. Creating the goal list is itself a motivational intervention. The client may not appreciate that one consequence of addictive behavior is an increase in emotional or behavioral problems. Indeed, these problems may resolve when addictive behavior is reduced or ended. In many, if not most addiction cases, the primary focus in sessions is co-occurring problems (which include co-occurring disorders). The other chapters will thus be highly relevant to the clinician treating addiction. However, clients do not care whether a diagnosis applies to their pressing problems; they just want help with them! If we focus on co-occurring disorders alone (all clients have the broader category of co-occurring problems), then in addiction treatment settings, most clients have additional diagnoses. In a mental health setting, comorbidity is lower but still common.
Addictions 191
Coping With Craving For some clients, craving is not a critical issue. However, for other clients, “I need this” becomes especially believable when craving is present. When a client experiences intense craving, almost nothing else is in the client’s awareness. Does the client understand craving sufficiently in order to cope with it effectively? A powerful, yet typically safe, approach is to discover past experiences of successful coping with craving. These experiences generally occur when a sudden change in situation brings to mind a priority higher than the addictive behavior. For instance, the client may have planned to get intoxicated, but then their ex-spouse called with a last-minute request to watch the children, who, for this individual, are a high priority. Ideally, a discussion of such episodes will clarify the roles of three accurate beliefs about craving: (a) it is time-limited, (b) it is not harmful, and (c) it does not force the client to do anything. Careful interviewing can elicit the client’s experience of the accuracy of each belief. The same set of accurate beliefs applies to panic attacks. Each client’s priorities, situations, and degree of self-control are different, but we assume that there are at least a few situations, even in the most severe cases, when other priorities will assert themselves. If addictive behavior is, in fact, the client’s highest priority at all times, then treatment is pointless. But this state of affairs is highly atypical and might be classified as suicide-by-addiction rather than addiction. If the client is physically dependent on the substance (e.g., alcohol), then control might be exhibited as allowing withdrawal to occur, or drinking just enough to prevent significant withdrawal symptoms, or tapering off over time. Once past success coping with craving is identified, then practicing coping with craving becomes less risky (but, in any event, should be undertaken cautiously). One way to begin this practice is to elicit craving at the beginning of a session (to allow time for it to dissipate) and then to move the discussion on to other topics and not address the craving at all, allowing the simple passage of time to result in diminished or evaporated craving. Although redirection, counter-argument, and distraction techniques can be used against craving (Horvath, 2004), many clients may wonder if they can apply these techniques well enough. However, all clients can simply wait until craving goes away. Monitoring craving and the responses to it would normally be a routine task in ongoing CBT for addiction. Ultimately, the client needs to have confidence that all routine life situations can be engaged without strong concern about craving, and that cravings that arise “out of the blue” can also be managed. Ongoing graded exposure therapy may be the most straightforward method to achieve this confidence. One very simple exposure method (which might also be termed willpower training) is to suggest that once the decision to engage in the addictive behavior is made, the client set a timer before acting. For instance, even if I have decided to drink, I can set the kitchen timer for 5 minutes before doing so. After the timer goes off, I can drink or set it again (for any period of time). Over time, I can set the timer for increasingly longer times, until eventually when it goes off
192 A. Tom Horvath
my mind has moved on and the craving has evaporated. In offering this suggestion, it is important to have the initial timer setting be quite short, seconds if necessary, so the client has a success experience. Relationships Although there may be a bias among clinicians for individual addiction treatment, the outcomes for couple or family treatment are at least as good (but beyond the scope of this chapter). Given that, for most individuals, there is no more important source of satisfaction and meaning in life than relationships, even if significant others are not in session, treatment should include a focus on improving these relationships. Resources for improving relationships, for both clinicians and clients, are easily available. Lifestyle Balance Addictive behavior is often used to redress quickly an imbalance that has built up over time. For instance, sleep deprivation leads to fatigue, which can be overcome by stimulants. Excessive concentration on work leads to tension, which can be resolved by drinking. Many clients need to review their knowledge of and habits regarding sleep, exercise, and nutrition, as well as other health habits and basic balances in life such as work versus play, social versus alone time, new projects versus maintenance activity, family time versus time with friends, activity versus contemplation, and so on (Horvath, 2004). Achieving better balance reduces the risk of craving, which in turn reduces the risk of recurrence. Meaning and Purpose in Life Ultimately, the purpose of resolving problematic addictive behavior is to live with greater purpose and meaning, which will lead, as a byproduct, to increased happiness. In the midst of major addictive problems, the client typically focuses almost entirely on a short time frame (hours to days). As change occurs, that time frame can increase, ultimately to a focus on activities that may extend beyond the client’s lifetime. The discussion of ultimate values and beliefs, and the day-to-day activities they imply for this client, may not typically be considered part of CBT. However, a well-entrenched addiction may require very high levels of persistent motivation to displace it, and such motivation may need to be based on the client’s ultimate values and beliefs. Many 12-step participants state that their motivation to change is ultimately founded on their acceptance of guidance from a “higher power.” Although theistic values and beliefs are not necessary for resolving addictive problems (even in individuals who are theistic), the 12-step approach demonstrates how focusing on ultimate beliefs and values is motivating. The identification of ultimate values and beliefs circles the client back to the search for motivations to change. Early in the change process, short-term motivations are identified (e.g., “I won’t be hung over in the morning”). As progress occurs, an ultimate value might emerge (e.g., “If I’m not drunk tonight and hung over tomorrow, I can
Addictions 193
be a much better father to my children”). Ideally the clinician repeatedly reflects back to the client progress toward higher or ultimate goals. Initially, clients are motivated to escape the pain that brought them into treatment (the precipitating event). However, over time, the pain of the precipitating event fades in memory, and craving tends to reassert itself. Until it does, there may be a “honeymoon period,” when the clinician can help the client gain greater confidence in experiencing longer term satisfactions in order to leave problematic addictive behavior behind.
SPECIAL CONSIDERATIONS WITH THIS POPULATION Medical Considerations Ideally, each client is also under the care of a physician. If so, the nonmedical therapist need only stay in contact with this physician as needed. It may be necessary to strongly (and perhaps repeatedly) encourage the client to seek such care. Beyond all the possibilities for medical complications from substance use, the primary treatment concern is withdrawal from alcohol or other central nervous system (CNS) depressants (e.g., benzodiazepines like Xanax or Valium, or barbiturates). If a client stops these substances suddenly, a withdrawal syndrome may develop. Severe withdrawal syndromes may be fatal, especially in someone medically compromised. Withdrawal from opiates, which have similarities to CNS depressants but also significant differences, is quite uncomfortable but rarely fatal. Nevertheless, even in these cases the client should be referred to a physician. By comparison, significant withdrawal from stimulants and most other substances will be uncomfortable but not dangerous. Therefore, substances can be divided into two broad groups: (a) those that can be stopped suddenly and (b) those that need to tapered over time or have medically managed detoxification. The CNS depressants and opiates can be compared to scuba diving. With enough time at significant depth, the body accommodates to the pressure of the water (a kind of “depressant”) and cannot return quickly to the surface without significant negative consequences (the bends). Other substances are like taking a hot air balloon ride, which can end safely with a quick return to the original altitude. Some clients are not willing to seek medical care, often for privacy reasons. They may have experience managing withdrawal symptoms or may be able to taper successfully. In some cases, they may know substantially more pharmacology than the psychotherapist. Nevertheless, referral to a physician is ideal. Medication-assisted treatment (MAT) also involves a physician. In this approach, the patient is given a medication that substitutes for the original substance (e.g., methadone or buprenorphine for opiates) or one that interferes with what has been the typical use of the substance (e.g., disulfiram, naltrexone, or acamprosate for alcohol; naltrexone for opiates). The use of a substitute has been controversial because the client is not abstinent. However, substitutes are perhaps more effective than any other approach to treating opiates, to the
194 A. Tom Horvath
degree that once a substitute is in place clients often no longer seek psychological services. Clinicians whose MAT clients discontinue psychotherapy can reach out to them with an open invitation to return when the time seems right. Residential Treatment, Outpatient Treatment, and Ancillary Services Generally, recommendations about these options should be made by addiction specialists. Residential treatment is overemphasized in the United States and does not provide, in most cases, increased effectiveness when compared with outpatient (Miller & Hester, 1986). Families may believe they know best and that “rehab” is definitely needed. However, other options may achieve the peace of mind they are seeking and also help the client. Admission for detox (detoxification) may be an essential first step (per the physician involved). It can be accomplished, typically over a span of days, and sometimes as an outpatient, without continuing on in residential treatment. Mutual Help Groups For many clients, the availability of free mutual help groups is a powerful adjunct to treatment. Clients should be encouraged to consider one or more mutual help groups and attend if these groups appear helpful. The most widely available groups are Alcoholics Anonymous (AA) and the several dozen offshoots of it, including Narcotics Anonymous (NA), Cocaine Anonymous (CA), and Gamblers Anonymous (GA), collectively known as 12-step groups. AA itself is effective if the participant is sufficiently engaged (Kelly, 2017). Although 12-step groups are often the only mutual help group referred to, there is now evidence that other groups are equally effective. In a 1-year longitudinal study comparing four mutual help groups (i.e., AA, SMART Recovery [Self Management And Recovery Training], LifeRing Secular Recovery, and Women for Sobriety), participants equally involved in each group had comparable outcomes (Zemore et al., 2018). These three relatively new options are significantly different than AA in varying degrees, including (because of a decreased [or no] emphasis on spirituality) conversational meetings, and a self-empowering (rather than a “you-are-powerless-over-this-disease”) orientation. SMART, in particular, is highly compatible with CBT (Horvath & Yeterian, 2012). However, in most localities, these groups are not readily available, and their online versions may be insufficient for many people. Fortunately, participation in mutual help groups, 12-step or otherwise, is not essential for change. Although the differences between, for instance, AA and SMART appear to be substantial on the surface, it now appears likely that all of these groups work because of the common factors available in any mutual help group, especially the acceptance into the group’s social network (Kelly, 2017). Therefore, these groups cannot be distinguished on the basis of their effectiveness or their mechanisms of behavior change. However, many individuals will find one group
Addictions 195
superior to the others because of the approach to change it uses. AA’s powerlessness, spiritual approach or SMART’s self-empowering, CBT and motivational interviewing approach appeal to rather different groups of clients. Nevertheless, some individuals attend both groups. Genetics Although genetics can be a powerful influence in the development of problematic addictive behavior, they have a small role in addiction treatment. Perhaps because of the influence of the idea that “addiction is a disease,” many clients are interested in the genetic impact on their addiction problems. Just as many other behaviors and traits do, addictions run in families (Enoch & Goldman, 2001). Individuals who especially enjoy one or more substances (not all individuals enjoy all substances) probably inherited the biochemistry that allows for this enjoyment. These individuals may also have a high natural tolerance for one or more substances, which postpones negative consequences from the substance until higher doses are used. Impulsivity-related traits, including lack of premeditation, sensation seeking, and lack of perseverance, are genetically influenced and associated with having addictive problems (Kale et al., 2018). In treatment, these genetic differences should be acknowledged and addressed to the extent they can be addressed. Outdated Terms and Treatment Techniques Although there are many media portrayals about how family members or professionals need to “confront” addicts and alcoholics in order to break down their denial and initiate recovery, this approach is not part of CBT and not supported by evidence (Smith & Meyers, 2004). Moreover, “addict,” “alcoholic,” and “chemical dependency” remain widely used terms. The DSM-III supported the use of better terms, and DSM-5 continues that support. The language used to describe our clients influences how we interact with them and how they think about themselves (Kelly et al., 2016). By using current and nonstigmatizing language (such as the language in Figure 6.1, except abuse, dependence, and addiction), we increase the chances that treatment will be helpful. Confrontation (“You MUST stop drinking”) is still widely used, but it can be counterproductive: “When one’s freedom is threatened there is a natural tendency to reassert it” (Miller & Rollnick, 2013, p. 143; Brehm & Brehm, 1981). A motivational interviewing approach is much more likely to help the client remember how longer term goals are not being served by current addictive behavior (Miller & Rollnick, 2013) and to consider making new choices. In this approach, denial is understood as a description of a type of interaction between clinician and client, rather than as a trait of the client. Denial can disappear when the clinician changes how the discussion is being conducted by using autonomy-supportive language. If we do not insist our clients accept a label (addict or alcoholic), do not generalize from having one or a few substance
196 A. Tom Horvath
problems to having problems with all significantly intoxicating substances (chemical dependency), and do not confront them because they are in denial, but rather inquire about what is important to them both now and in the future, we can build an alliance in which their energy can be used to address their problems and change, rather than to fight off our attempts to control their thinking.
OUTCOME DATA CBT is approximately as effective as any other treatment for addiction. The evidence for its effectiveness now spans decades (Carroll & Kiluk, 2017). In a meta-analysis of 53 randomized controlled trials of CBT for alcohol and illicit drug disorders, Magill and Ray (2009) found that Across studies, CBT produced a small but statistically significant treatment effect (g = 0.154, p < .005). The pooled effect was somewhat lower at 6–9 months (g = 0.1 15, p < .005) and continued to diminish at 12-month follow-up (g = 0.096, p < .05). The effect of CBT was largest in marijuana studies (g = 0.513, p < .005) and in studies with a no-treatment control as the comparison condition (g = 0.796, p < .005). (p. 516)
Even though no treatment is more effective than CBT for addiction, there are several treatments as effective. All three arms (i.e., CBT, 12-step facilitation and motivational interviewing) of Project MATCH (Project MATCH Research Group, 1997) had approximately the same outcomes, even at 1-, 2-, and 3-year follow-ups. Imel et al. (2008), in a meta-analysis, found that a wide range of rather different treatments for alcohol problems appeared to be equally effective. Even if CBT is no better on average than some other addiction treatments, might it be better for specific types of individuals? One of the goals of Project MATCH was to identify variables that might be used to match clients to the three types of treatments offered. No highly clinically significant matches were found. Other attempts at matching have also yielded minimal results. For now it appears that, just as with mutual help groups, clients will need to sort themselves into treatments. For clients seeking a fact-based, self-empowering, and reasoned approach to change, CBT is likely to be appealing. Clinicians can confidently use CBT for addiction but should refrain from stating that it is better than other approaches. Nevertheless, CBT is likely to remain a treatment of choice, and an option offered by competent clinicians and much sought out by clients for years to come.
MECHANISMS OF CHANGE Just as mutual help groups for addiction, despite their significant differences on the surface, may have the same mechanisms of change, so too with addiction treatments (or at least with alcohol treatments, where there are sufficient data
Addictions 197
from which to draw conclusions). If we assume that CBT for alcohol problems offers a unique approach by helping clients identify and change dysfunctional thoughts, beliefs, and behavior, then we should find that CBT (a) is better overall; (b) is better for some definable group; or (c) changes thoughts, beliefs, and behavior in expected ways. However, there is insufficient evidence to firmly support any of these ideas for CBT in general (Wenzel, 2017). As Imel et al. (2008) concluded in their review of alcohol treatment specifically, Although a lack of evidence in regards to treatment differences cannot fundamentally resolve the polemic between the models of treatment, our findings suggest that additional head-to-head comparisons of bona fide psychological treatments are unlikely to provide further answers. In addition, our findings are consistent with: (a) mixed findings in regards to matching specific client diagnostic traits to treatment characteristics and (b) a failure to find consistent patterns of theory specific mediation and moderation of treatment effects . . . research that looks beyond the therapeutic rationale as a guide to the psychological mechanisms responsible for change, to potentially more universal change factors may be increasingly beneficial. (p. 541)
For now, we need to preserve and advance CBT and other established treatments because they are working, but recognize that we have much to learn about treatment. One promising mechanism of change in CBT for addiction is the use of homework. Homework has long been considered an important aspect of CBT for addiction (Beck et al., 1993). Carroll and colleagues found that “participants who completed more homework assignments demonstrated significantly greater increases in the quantity and quality of their coping skills and used significantly less cocaine during treatment and through a 1-year follow-up” (Carroll et al., 2005, p. 794). Beyond homework specifically, CBT for addiction includes components that may yet be identified as mechanisms of action, including examining and preparing for high-risk situations (including refusal skills), changing inaccurate beliefs about craving, and emphasizing the autonomy of the client and the choices available. In order to advance the clinical practice of CBT, common clinical errors (Kim et al., 2016) need to be avoided. These errors include insufficient functional analysis, an insufficient goal list and case conceptualization, challenging seemingly irrational thoughts rather than investigating them, and not staying on the course set by the goal list and case conceptualization if problems arise (rather, such problems should be investigated and resolved or a course correction made). If CBT proves to provide factors beyond common factors of change, by avoiding these errors we increase our chances of providing these unique factors.
DISSEMINATION The use of CBT in specialty addiction treatment facilities is widespread, if only because of relapse prevention training. However, the underlying ideas of relapse prevention (which includes a harm reduction orientation) may not be
198 A. Tom Horvath
given much weight. Rather, relapse prevention may be taught as a set of techniques. This chapter’s approach to CBT appears not to have been disseminated widely. How soon this situation will significantly change is hard to predict. Kiluk et al. (2017) found evidence that CBT4CBT (computer-based training for cognitive-behavioral therapy) improved treatment outcomes when added to treatment as usual: “In this methadone maintained sample, those with poorer quality skills in response to certain high-risk situations at baseline appeared to improve their coping strategies following CBT4CBT compared to standard methadone treatment alone” (p. 87). This software could be disseminated inexpensively. The opportunity for the dissemination of CBT for addiction to the large number of psychotherapists who already know CBT is promising. Some of these psychotherapists may need to move beyond the belief that addiction needs to be treated only by individuals with lived experience and only by using a 12-step, disease model approach. SMART Recovery is also disseminating CBT concepts (including those of REBT [rational emotive behavior therapy], DBT [dialectical behavior therapy], ACT [acceptance and commitment therapy], and others). However, it may be some years before SMART meetings are very widely available. Nevertheless, SMART may be the most effective method for disseminating CBT concepts and treatment because its meetings are free and open to the public. As participants in SMART cycle in and out of the U.S. treatment system, they may insist upon services consistent with their experiences in SMART.
APPLICATION TO DIVERSE POPULATIONS Any CBT for any disorder is capable of being completely personalized to the individual client. However, because CBT emphasizes using scientific facts, reasoning, and identifying and modifying unhelpful thoughts and beliefs, these emphases may resonate with privileged populations (who view them as skills that helped them attain and maintain their current societal position), rather than the underprivileged. However, CBT has been offered in large, federally funded addiction treatment studies, using community-based samples with diverse populations. For instance, in Project MATCH the outpatient arm of the study (952 subjects) was 28% female, 64% single, 80% White, 49% unemployed, and had 13.4 years of formal education (SD = 2.2 years; Project MATCH Research Group, 1997). In these studies, CBT works as effectively as other treatments. Above and Beyond in Chicago is an example of CBT in a diverse community setting. Since being established in 2015, this community clinic has served over 2,000 clients, a largely African American and underprivileged population, with substantial levels of illiteracy, past incarceration, and past homelessness. Clients are free to choose 12-step or SMART Recovery track. The SMART track is chosen by approximately 90% of clients (D. Hostetler, personal communication, January 30, 2018).
Addictions 199
SMART Recovery also has emerging groups in prisons and other correctional settings and was the subject of a large study (N = 5764) in the Australian prison system (Blatch et al., 2016), where a significant portion of the population is underprivileged. Participants who attended both a SMART training program and a SMART mutual help group had significantly lower percentages (compared with controls) of reconviction for general offenses (21%) and for violent offenses (42%).
CLINICAL EXAMPLE This idealized version of an initial interview and treatment plan may substantially underestimate how much time might be needed with some individuals. Issues addressed here in a few sentences might require entire sessions. THERAPIST: How can I help you? CLIENT:
I want to know if I’m an addict or not.
THERAPIST: Unless you have freely chosen that term it’s often unhelpful.
Everyone’s addictive problems are unique. How about if we focus on the problems you have and how to solve them? CLIENT:
Well, I have lots of problems: Alcohol, especially vodka, meth sometimes, food a lot, and sometimes gambling. I smoke weed every day too, but I don’t really think that’s a problem. Do you?
THERAPIST: Your substance use is up to you. I’m glad weed does not seem to
be causing major problems. CLIENT:
But that’s the thing: I pretty much get into trouble with anything addictive. Even TV! I binge watch shows and even YouTube. That’s why I think I’m an addict. I used to shoot coke and smoke heroin too, but they scared me too much, so I quit.
THERAPIST: Congratulations, that’s a big accomplishment. CLIENT:
I suppose so, but all these other problems too! Booze is now the worst. My doctor told me my liver is starting to get bad. Maybe I’m just an alcoholic, not an addict.
THERAPIST: That’s another probably unhelpful term. What would you like to
do about your drinking? CLIENT:
I’d love to moderate. I just don’t know if I can.
THERAPIST: How often have you tried? CLIENT:
Many times. Sometimes I’m successful, sometimes I’m not. If the craving gets strong, I just give in.
200 A. Tom Horvath
THERAPIST: I could teach you techniques for coping with craving. But, actu-
ally, you already know about them. You just don’t realize it. You were successful with coke and heroin, right? CLIENT:
Yeah. That was interesting. It was like a switch got flipped in my head. I did have cravings, sure, but I had made up my mind.
THERAPIST: How were you able to make up your mind so firmly? CLIENT:
I could see where the coke and heroin were leading me. Two friends OD’d, and one went to prison for dealing. I’m smarter than all of them, but it seemed like in time even being smart wouldn’t keep me out of trouble.
THERAPIST: That’s impressive. You made a long-term decision, based on how
you want your life to go, and you stuck with it. CLIENT:
Yeah, actually I’m kinda proud of myself. But not with alcohol! I never liked the other stuff as much as I like booze.
THERAPIST: That often happens. Many people have one or a few favorites.
The rest are easier to deal with. CLIENT:
I get it. Alcohol is the tough one for me.
THERAPIST: What do you like about drinking? CLIENT:
Where do I begin? When I’m amped up, it calms me down. When I’m bored it gives me a lift. I can’t imagine partying without it, or winding down without it. When I’m stressed, it’s the best. Once I get going that’s all I want to do. I do moderate sometimes, but sometimes I just go for days.
THERAPIST: Alcohol is valuable for you. You like what it does for you. CLIENT:
I do. I really do.
THERAPIST: Did something happen recently that led you to call me? CLIENT:
I’m too embarrassed to talk about it. But let’s say that, if I don’t change, I’m going to get kicked out of the house. I think she means it this time. And I actually want this relationship. It’s the best one I’ve ever had. I love her, and I know she loves me. But not my drinking!
THERAPIST: I’m sorry, that’s a painful spot to be in. You love her, and you
love alcohol, and having both is looking difficult. CLIENT:
She says I need to work on my demons. Like I’m possessed! But in a way I am. My dad was a boozer. He never beat me, but I always thought he would. When I got to be 10, I finally realized he was always too drunk to do anything more than scream at
Addictions 201
me. But by then a lot of damage was done. I’m still way too scared, too much of the time. I guess booze really helps with that. THERAPIST: I’m sure it does. Alcohol may be cheaper, faster, and more effec-
tive for anxiety than anything else on the market. Unfortunately, it has some unfortunate long-term negative effects. CLIENT:
I’ll say. But yes, the booze really works. I don’t know what I’d do without it.
THERAPIST: Actually, you may know more than you realize. After all, you
quit coke and heroin. How did you do it? Somehow you learned to live without them. CLIENT:
True. But alcohol will be harder.
THERAPIST: Sounds like you might be deciding it’s time to change. CLIENT:
I don’t want to get kicked out of my place. She’s right, really. Alcohol is killing me. And I really don’t want to lose this relationship!
THERAPIST: Are you changing for her or for yourself? CLIENT:
You ask tough questions!
THERAPIST: I hope they’re helpful. That’s actually an important question.
We’ll probably talk about it more. CLIENT:
I do want to be a better partner. I do want to keep this relationship. I do want to keep my health. I do want to end up not like my old man. Huh! I guess I do want to change. But could I still moderate?
THERAPIST: No one seems to know how to predict with much accuracy
whether any individual can moderate. But we can find out in your case by trying, if that’s what you want to do. CLIENT:
Some doctor once told me moderation was impossible for someone like me. What do you think?
THERAPIST: We can find out by trying. But keep in mind that trying moder-
ation and not succeeding would be risky. How many more benders do you think she will tolerate? CLIENT:
I’m lucky I’m still alive now! Just joking, she’s not violent. But I’ll never forget the look on her face after the last one.
THERAPIST: She got your attention. One option to consider is an extended
period of not drinking. I’m thinking a year, but it’s your decision. It would create good will at home, and it would give you time to
202 A. Tom Horvath
learn what you need to learn. Then at the end of that time you could reconsider the whole issue. CLIENT:
Actually, that sounds sensible, but it still scares me. Alcohol is a lot to give up. In some ways, it’s been the best friend I ever had.
THERAPIST: I believe you. CLIENT:
Still, as you said, I did it with coke and heroin. Oh, did I mention cigarettes? I quit smoking over 3 years ago.
THERAPIST: Congratulations, another big accomplishment. How hard was it? CLIENT:
Unbelievable! I knew I wasn’t going to smoke, but wow! What a pain! And for weeks!
THERAPIST: How often do you want to smoke now? CLIENT:
I almost never think about it anymore. Gee! That’s pretty good, isn’t it!
THERAPIST: I agree. And it shows you what’s possible. In fact, when it’s all
done, you may say that smoking was harder to change than drinking. CLIENT:
I had a friend tell me that. She quit heroin and cigarettes. She liked heroin more, but cigarettes were harder.
THERAPIST: So are you ready to take on this project? CLIENT:
As ready as I’m going to be. But I’ll need help.
THERAPIST: Understood. Let’s review a moment. You came here because you
don’t want your relationship to suffer from drinking. You like drinking in many ways, but the costs have become too high, in particular because your relationship is very important to you, and you also want to keep your liver. You are ready to abstain for now. I proposed a year, but we didn’t finalize that timeframe. For now, would you consider a month? CLIENT:
I could do a month. I’ve done that before.
THERAPIST: Good, we can reconsider in a month. You’ll need to learn how to
wind down from stress without alcohol, and there may be other skills to learn as well. That will be some of our most important work. You’ll also need to think about how important this change is for you, rather than just your partner. Does my summary sound accurate? CLIENT:
Yes, thanks.
THERAPIST: Okay, one immediate item is your recent drinking and the possi-
bility of withdrawal symptoms. Did you drink today?
Addictions 203
CLIENT:
Nope. I tapered off last week. I haven’t had a drink in four days. I’ve tapered before, because a few years ago I had withdrawal symptoms. They weren’t severe, but they were pretty uncomfortable. So I’m okay now.
THERAPIST: Good. And when do you see your medical doctor next? CLIENT:
Should I go again?
THERAPIST: That would be safest. I encourage you to do so. CLIENT:
Okay, I’ll get an appointment.
THERAPIST: And if you misjudged about withdrawal symptoms, call your
doctor or go to the emergency room immediately, okay? CLIENT:
Thanks, but I’ll be fine.
THERAPIST: Understood. Let’s spend the rest of today making an initial plan.
We may not get to everything today, so let’s begin by deciding when to meet next. What do you think? CLIENT:
I don’t know, what do you think?
THERAPIST: How is tomorrow? CLIENT:
Really? Fine by me.
THERAPIST: You’ll see, before long we may hardly be seeing other, perhaps
only once a month. But it’s good to start strong. CLIENT:
That’s good, actually. I only have one night to get through right away.
THERAPIST: Here’s my proposed agenda for the rest of this session. How does
this sound? Let’s talk about how to get through the rest of today, including how to relax tonight, how to cope with craving, what to tell your partner about this session, and how soon we might have a couple’s session. Sound okay? CLIENT:
Yes, that’s good. Especially the part about a couple’s session. I think she’d like to meet you.
THERAPIST: Good to know. If we have time today we can also discuss what
your other goals for being here are, including all those other substances and activities you mentioned, whether you will attend a mutual help group like SMART or AA, whether addiction medications or psychiatric medications might be helpful, and what to talk about with your medical doctor. Soon, you can also tell me your drinking story and your life story, including where you see your life heading. We’ll also talk about—and this will be a big part of our conversation—what healthy habits you can add to your life and, most importantly, what your life is
204 A. Tom Horvath
going to be about if drinking isn’t in the picture. I know this is a lot to keep track of, but that is my job. For now, you just need to get through tonight, so let’s talk about that. CLIENT:
Sounds good. Here we go!
THERAPIST: Let’s start by considering what would be helpful tonight, based
on what you’ve already accomplished with smoking, coke and heroin. . . .
CONCLUSION CBT for addiction (problematic addictive behavior) has a well-established scientific history and foundation, is as effective as other addiction treatments, addresses the underlying belief that the addictive behavior is needed in the client’s life (and related unhelpful beliefs), can be used in a highly flexible manner (including the options to pursue harm reduction and moderation as well as abstinence), and can be used with underprivileged populations. For clients who prefer a fact-based, self-empowering, and reasoned approach to addiction treatment, CBT may be the treatment of choice.

he symptoms that comprise bipolar disorder, though not always wellunderstood in the past, have both fascinated and frightened sufferers and observers throughout history, and have been associated with tragic heroes from Greek mythology to temperamental Romantic Era writers, artists, and musicians (Jamison, 1993). Kraepelin (1921) pioneered a scientific approach to the study of this area of psychopathology, painting a bleak picture of an unglamorous life of inexorable neurocognitive deterioration. Decades later, with the advent of pharmacologic treatments such as lithium, there was a greater sense of hope regarding the prognosis for persons suffering from bipolar disorder (Tondo et al., 1997). More recently, a range of evidenced-based psychosocial treatments—including cognitive behavioral therapy (CBT)— have shown promise in adding significantly to the overall treatment of bipolar disorder, emphasizing such skills as objective self-monitoring, behavioral moderation, regulation of sleep-wake patterns, improved communication and interpersonal collaboration, and metacognition, including rational responding and modifying maladaptive schemas (S. L. Johnson & Leahy, 2004; Reiser et al., 2017).1 Bipolar disorder consists of a wide spectrum of symptoms, and the course of the illness is highly variable. Though there are core principles of CBT that are applicable regardless of the condition in which a particular patient presents in a given session, an effective cognitive behavioral practitioner has to be able to assess changes (sometimes frequent and rapid) in a bipolar patient’s state of Clinical examples are disguised to protect patient confidentiality.

mind and level of functioning, and to adapt the therapy agenda accordingly. Thus, the heterogeneity of bipolar disorder poses complexities in assessment and treatment planning (S. L. Johnson & Peckham, 2018). The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5; American Psychiatric Association, 2013) describes the many facets and subcategories of bipolar disorder. For example, the DSM-5 criteria for bipolar I disorder specifies the presence of at least one lifetime episode of mania, a term which is defined in such a way as to distinguish it from the less extreme but still problematic hypomania, which may also be present in bipolar I. However, if a patient is determined to have had a history of at least one major depressive episode and at least one hypomanic episode, but not a period of full-blown mania, this is designated as bipolar II. In spite of the lack of a full-blown mania, bipolar II should not be taken lightly, as it often confers serious symptoms on its sufferers, such as significant depressive episodes (with the potential for suicidality) and varying levels of functional impairment. Another variant is cyclothymic disorder, which comprises “chronic fluctuations between high and low moods that are not severe enough to qualify as episodes, yet persist for two years (or one year among children and adolescents)” (S. L. Johnson & Peckham, 2018, p. 253). Again, one should not be lulled into clinical complacency by the phrase “not severe enough to qualify as episodes.” For example, in a study of pediatric bipolar disorder, Freeman et al. (2009) reported that youth with cyclothymia have a lower quality of life and fewer days of quality functioning than their matched peers with serious medical illnesses. DSM-5 also describes “bipolar and related disorder due to another medical condition,” as well as “substance/medication-induced bipolar and related disorder” when sufficient mood symptoms have been triggered by the use of or withdrawal from substances. There is also a grab-bag category of “other specified bipolar and related disorders” (formerly called “bipolar disorder not otherwise specified”) that subsumes bipolar symptoms that do not meet full criteria for other sub-categories, such as short-duration hypomanic episodes (e.g., 2 to 3 days), as well as “unspecified bipolar and related disorders” when there is a probable but unverified history of manic symptoms. Add to all of these designations the myriad specifiers such as “with anxious distress,” “with mixed features,” “with rapid cycling,” “with psychotic features,” and others, and one can readily see the inherent difficulties in devising a treatment for bipolar disorder as if it were a single entity. For the sake of convenience, this chapter will choose the generic term bipolar disorder to refer to the entire bipolar spectrum, and will use subcategories when deliberately zeroing in on a specific type of bipolar disorder. Much of the literature on CBT for bipolar disorder is meant to refer to bipolar I (S. L. Johnson & Peckham, 2018), but this chapter describes interventions that may be used more broadly unless otherwise indicated. Another factor that potentially complicates the description of a given treatment for bipolar disorder is the fact that comorbidity is so prevalent (S. L. Johnson, 2004). Three top examples are anxiety disorders (as high as 60% to 75%; Goodwin & Hoven, 2002; Merikangas, & Kalaydjian, 2007), alcohol and other
Bipolar Disorder 209
substance use disorders (up to 50%; Sherwood Brown et al., 2001; Zarate & Tohen, 2001), and personality disorders (ranging from 33% to 50%; e.g., Üçok et al., 1998). These additional diagnoses require more comprehensive treatment planning, with special attention paid to increased risk of medication nonadherence and suicidality (Üçok et al., 1998; Vieta et al., 2001). Bipolar disorder requires a longitudinal treatment plan given the disorder’s likely effects across the lifespan. Although CBT has a reputation for being time-effective, and for teaching patients durable coping skills that improve self-efficacy and help maintain gains over the long term, it is still often necessary to have repeated periods of CBT over the years, superimposed (ideally) on an ongoing regimen of pharmacotherapy (Newman et al., 2001; Reiser et al. 2017). Unless the cognitive behavioral practitioner is licensed to prescribe medications, the treatment will likely necessitate collaborative care between at least two mental health professionals. Such coordinated care requires good working relationships among the parties, including periodic communication, mutual support for and understanding of the respective treatment approaches, and skillful handling of situations in which the patient is dissatisfied with or rejecting of one of the treatments. It is helpful to think of CBT and pharmacotherapy as having points of overlap rather than as entirely separate treatments. For example, when pharmacotherapy is improving a patient’s stability of functioning, it facilitates the patient’s participation in CBT, including attendance, learning coping skills, and doing homework assignments. Similarly, when patients learn the CBT skills of self-monitoring and rational responding, they are in a better position to take their medications as prescribed and to identify and modify any excessively negative beliefs they may maintain about their medications (e.g., “I will lose my true self if I take medications”). Indeed, there can be a synergy between psychosocial and pharmacologic treatments (Basco, Ladd, et al., 2007; Sudak, 2011).
UNDERLYING THEORY Classic models of cognitive vulnerability in depression—including Beck’s (1967) model of negative self-schemas, Seligman’s (1975) learned helplessness model, and the hopelessness model (e.g., Abramson et al., 1989)—have been extended to bipolar spectrum disorders (e.g., Alloy et al., 2006). Alloy et al. (2018) reviewed the research indicating that the same cognitive styles hypothesized to be risk factors in unipolar depression may increase vulnerability to bipolar depressive episodes, stating, “Generally, many studies have indicated that individuals with BSD [bipolar spectrum disorder] in a depressive episode exhibit underlying cognitive styles at least as or more negative than those of unipolar depressed persons and more negative than those of healthy comparison individuals” (p. 111). The authors noted that bipolar sufferers in a depressed state also demonstrate negative cognitive biases on implicit tasks. Interestingly, Alloy et al. (2018) added that “hypomanic BSD individuals often present positive
210 Cory F. Newman
cognitive styles on explicit measures, but continue to exhibit evidence of underlying negative cognitive styles on implicit assessments” (p. 111). For example, a person in a manic state may experience a dramatic shift in mood valence such that they feel extremely attractive, with a desire to charm and seduce others, while still harboring self-doubts and a core belief of not being lovable, which is manifest in hiding away from others when depressed. Thus, the state of the person’s mood and belief may change with the phase of the illness, but the basic underlying vulnerability to feeling unlovable may remain. From a neurobehavioral perspective, there is evidence that persons with bipolar illness possess a hypersensitive behavioral approach system (BAS), a rewardfocused, motivational system involved in goal-striving and attainment of rewards (see S. L. Johnson et al., 2012). The BAS, which has been linked to a dopaminergic frontostriatal neural circuit activated by internal or external reward-relevant stimuli, is associated with increased motor activity, magnified focus on incentives (and less relative focus on risk), and heightened positive emotions associated with striving for goals (Gray, 1994; Haber & Knutson, 2010). Its corresponding cognitive styles include perfectionism, high valuing of autonomy, overambitious pursuit of goals, and marked self-criticism when these high goals are not met (Alloy et al., 2009). Data from recent studies are congruent with an integration of the cognitive models and BAS theories of bipolar disorder. For example, Lam et al. (2004) measured the cognitive styles of persons with unipolar depression and bipolar disorder via the Dysfunctional Attitudes Scale (Weissman & Beck, 1978) and found that the individuals with bipolar disorder scored higher than those with unipolar depression only on goal-attainment attitudes. Examples of such items included, “A person should be able to control what happens to him,” “I ought to be able to solve problems quickly,” and “If I try hard enough, I should be able to excel.” Similarly, Shapero et al. (2015) found that persons with bipolar disorder were more ambitious in their goal striving than depressed persons, but they were also more self-critical. Additional evidence for cognitive vulnerability to bipolar symptoms from a BAS perspective comes from Lozano and Johnson (2001), whose data indicated that cognitive styles involving the need for high achievement predicted increased manic symptoms over a period of 6 months. Rather dramatically, Alloy et al. (2012) studied adolescents with no prior history of bipolar disorder and (when controlling for initial mood symptoms and family history of bipolar disorder) found that ambitious goal-striving predicted first onset of bipolar disorder over a 13-month follow-up. Although BAS appears to be a feature that is particularly relevant to bipolar disorder, the preponderance of evidence seems to suggest that similar maladaptive cognitive styles may serve as vulnerabilities to both unipolar and bipolar mood disorders (Alloy et al., 2018). The dysfunctional attitudes, maladaptive self-schemas, and attributional styles described in hopelessness theories and Beckian cognitive theory appear to exhibit some independence from current mood state but predict onset and recurrence of symptom episodes in bipolar
Bipolar Disorder 211
disorder, both spontaneously and in conjunction with life events that interact with the patient’s cognitive style. For example, the self-image of bipolar patients is composed of a complex combination of both positive and negative self-regard (e.g., Scott & Pope, 2003; Winters & Neale, 1985), though the “hyperpositive” aspects of self-image tend to emerge as a prodromal sign of hypomania (Goldberg et al., 2005; Lam, Wright, & Sham, 2005). These findings have direct therapeutic implications, in that cognitive-behavioral interventions need to help bipolar patients moderate their goal pursuits and self-image whilst taking care not to exacerbate the aspects of their thinking that are self-doubting and self-denigrating. Bipolar patients also demonstrate poor autobiographical recall (i.e., highly general and nonspecific) for both negative and positive life events, even exceeding the difficulties exhibited by persons with unipolar depression (Mansell & Lam, 2004; Scott et al., 2000). Cognitive behavioral practitioners can use guided imagery to help patients retrieve the specifics of important memories so that cognitive restructuring and problem solving can proceed effectively (Mansell & Lam, 2004). Alloy et al.’s (2018) summary of the above findings (and more) indicates that future research will continue to take into account the integration between cognitive and neurobiological models of bipolar disorder. Life events also play an important role in the development and expression of bipolar symptoms. S. L. Johnson et al. (2016) reported that childhood abuse is associated with greater severity of bipolar illness. Similarly, exposure to trauma at any age is related to chronic stress and greater reactivity to negative life events that worsen the course of the disorder. Further, family difficulties that include patterns of aversive interactions predict an increase in bipolar symptoms, particularly depression. Lack of social support in general is yet another exacerbating factor (S. L. Johnson et al., 1999). Similar to problems with patients’ problems with cognitive biases and dysfunctional behavioral habits, environmental hardships are important targets for intervention in CBT. The problems above can be targeted together in CBT, as there is evidence that stressful life events, cognitive vulnerabilities, and mood symptoms all influence each other (Calvete et al., 2013). In summary, the CBT model of bipolar disorder strives to find a conceptual bridge between biology, beliefs, and behaviors; between triggering life events and patients’ individual ways of making meaning out of these events; and between cognitive-emotional “states” and “traits.”
THE THERAPEUTIC RELATIONSHIP An important part of establishing a healthy, constructive therapeutic relationship lies in providing good psychoeducation about bipolar illness and its treatment in a way that invites the patient’s input. As noted by Colom and Murru (2011), psychoeducation with bipolar patients should sound like it is coming from a place of partnership, rather than from authority, and in a spirit of mutual
212 Cory F. Newman
education, rather than the mere unilateral delivery of information. In this manner, trust and teamwork can be established. Therapists need to be able to offer validation for patients’ sense of despondency and demoralization when they are in their down phases, and yet still offer sincere reasons to have hope and to keep trying. This has to be balanced with being truly happy for patients when they are bursting with good mood in their “up” phases, and yet still being able to give them caring, corrective feedback about their hypomanic or manic behaviors and thoughts. In a related vein, therapists should not prejudge that a hypomanic patient’s stated ambitious ideas and goals are necessarily unrealistic. Therapists can be generally supportive of patients’ endeavors while still walking them through the steps of advance problem solving, weighing of pros and cons, and seeking consultation from trusted others. Additionally, when patients express weary distress about the toll taken by the cyclical ups and downs of their functioning, and/or ongoing worries about future symptom episodes, therapists need to acknowledge that bipolar disorder is indeed a major life burden whilst still extolling the virtues of maximizing healthy functioning through serious commitment to treatment. It is sometimes difficult for patients to accept their diagnosis. Even those who are willing to acknowledge that their symptoms are consistent with a bipolar diagnosis may be loath to accept a goal of averting hypomania, reasoning that this phase of the illness helps them in a number of ways and provides some measure of “compensation” for the misery of the depressive phases. To be maximally effective, therapists must try to avoid getting into power struggles with patients who express these viewpoints. Instead, therapists need to take an approach that is akin to motivational interviewing (Miller & Rollnick, 2002)—a therapeutic stance that is congruent with good CBT in that it emphasizes collaboration, guided discovery, empathy, and a striving toward graded improvements in function (rather than taking an “all or none” position about complying with treatment). A sense of collaboration is fostered when therapists show an interest in and respect for the patient’s goals, even while characterizing some of those goals as being potentially problematic (e.g., wanting to accomplish as much as possible when one’s mood is good, even if it means overworking and losing sleep). The therapist can state that it is understandable that the patient may not want to seek a stabilized mood when what they really want is maximum functioning. However, therapists can use guided discovery questions to help patients examine their own past experiences for evidence for and against the advisability of their goals. For example, the therapist may say, “I remember that you said you were able to work on multiple projects when you were in a manic phase, and that you enjoyed this, but I also remember what you said about the unintended consequences, and how you couldn’t count on yourself to sustain working on your projects, so a lot of work got neglected before you were ever able to finish it. How might you be able to achieve more of your goals going forward? How might a more stable mood serve a useful purpose for you?”
Bipolar Disorder 213
Therapists also realize that they cannot demand and dictate that patients automatically buy into the entirety of a “safe” treatment plan (e.g., taking appropriate medications, reducing excessive goal-directed behavior, getting feedback before acting on impulsive ideas), lest they risk straining the therapeutic relationship and perhaps losing the patient from treatment altogether. Instead, therapists find ways to engage the patients in pursuing goals where they show some agreement, reaching negotiated “compromises” in principle that are then evaluated in practice. For example, a patient who appeared to be exhibiting flights of thought, pressured speech, and grandiose ideation reported that he wanted to write a scientific textbook, and he explicitly asked the therapist for her opinion on this matter. The therapist recognized that the patient’s sense of self-efficacy was manically inflated, but she wanted to remain respectful of the patient even while trying to offer corrective feedback. Eschewing the all-or-none approach of telling her patient “flat out” that his thinking was manic (at one extreme) or risk positively reinforcing the patient’s grandiosity (at the other extreme), the therapist asked the patient if he would consider “running a pilot study.” The therapist explained that many major scientific projects start with a scaled-back version of a full study in order to collect data that will inform the larger project later on. She then suggested that the patient organize his hypotheses in the form of a short paper that could be submitted for publication as a feature piece in a popular scientific magazine. If this “pilot project” went well, then perhaps the patient could consider building on the paper to the point where it could become a book proposal. The therapist then added, “In the meantime, it is very important that you get enough sleep, and that you touch base with the psychiatrist, because having a strong desire to pursue demanding, time-consuming goals is one of those warning signs of mania we talked about, especially if you are tempted to work late hours.” In taking this “middle-ground” approach, the therapist was avoiding shaming or overcontrolling the patient while still advocating for limits and safeguards. An exchange of feedback is a key component of a well-run CBT session, as a means by which to clarify communication, to summarize key learning points, and to show mutual respect (J. S. Beck, 2011). In the case of bipolar disorder, cognitive behavioral practitioners make sure to ask patients their opinions about the session and about how they think they are being treated. They also give feedback to their patients, positively reinforcing the patients’ constructive efforts to engage with the treatment plan, and tactfully offering comments of concern if the patients appear to be off track or otherwise responding dysfunctionally. Toward this end, the following is a sample comment that therapists can make early in treatment: THERAPIST: We will work well as team if we can speak freely with each other
about important matters. I am depending on you to give me feedback about how you feel about our work together, and to let me know what seems helpful and what does not. On the flip side, I hope you will return the favor and allow me to give you
214 Cory F. Newman
feedback about how you’re doing in therapy. You can expect me to ask about your moods and thoughts every session, and to check on your between-session homework. If I see anything that concerns me, I won’t jump to conclusions about your state of mind until I point it out to you and ask you for your opinion. I hope that seems fair. I’m optimistic that we can give each other constructive feedback in a respectful way and make the most of this treatment. What do you think? It is in a spirit of teamwork that the specific interventions and related homework assignments will have their best impact. Patients will be more inclined to learn and practice psychological skills and therefore to maintain their gains, an outcome that is particularly important in the treatment of a disorder that requires long-term attention.
DESCRIPTION OF MAIN TREATMENT APPROACHES As noted, patients suffering from bipolar disorder may exhibit a wide range of symptoms, and the treatment landscape may change depending on the particular subtype(s) and/or phase of the illness that the patients demonstrate. As a reflection of this complex reality, the specific interventions described in this section represent a mixture of approaches, some more appropriate for patients in a depressive state, some more applicable to those who show signs of hypomania or mania, and some that may be utilized across the board. What the interventions have in common is an attempt to keep the patient’s functioning within normal limits and to provide compensatory coping strategies that include safeguards against overcompensating (such as when a person with bipolar depression engages in behavioral activation but takes care not to schedule too many activities that may interfere with sleep and risk potentially switching into hypomania). The first “intervention”—self-monitoring—also doubles as an assessment method. Self-Monitoring and Recognizing Prodromal Signs One of the most important skills that cognitive behavioral practitioners can introduce to their patients is to recognize early warning signs (i.e., “prodromes”) of symptom episodes, particularly hypomania or mania, in which patients may otherwise not think there is a potential problem. This intervention—which is an important subset of the overarching skill of self-monitoring—has solid empirical support (e.g., Lam et al., 2000; Lam, Hayward, et al., 2005; Perry et al., 1999). When patients are taught to self-monitor their moods, sleep patterns, behavioral activities, and feedback from others (as ongoing homework exercises), they gain valuable information as well as an increased sense of self-efficacy. Although there are some signs of impending symptom episodes
Bipolar Disorder 215
that are common across patients, there is also individual variability. Thus, it is important for patients to identify their own “relapse signatures” as part of this process of spotting prodromes (Smith & Tarrier, 1992). Although it may not always be possible to fully prevent a symptom episode, early detection can help patients take prompt, active steps (in terms of cognitive-behavioral interventions and/or supervised pharmacologic adjustments) that may reduce the intensity and duration of the symptoms along with their potential consequences. For example, a young man in CBT for bipolar disorder called his psychiatrist when he noticed that he was “happy to stay up all night,” which resulted in his being instructed to increase the dosage of one of his medications ahead of his appointment. Further, the patient also contacted his cognitive behavioral practitioner to schedule an impromptu session, during which they devised an updated treatment plan that included focusing on sleep hygiene, agreeing on a temporary moratorium on important life decisions, and enlisting the help of a friend and a sibling to spend more time with the patient (thus providing supervision during a critical time). The patient also diligently practiced his controlled breathing and relaxation skills (for homework, twice per day) so as to reduce excessive physiological arousal. The skill of self-monitoring, in addition to being a central feature of recognizing prodromes, helps patients to identify patterns of functioning that, if altered therapeutically, may improve the patients’ quality of life and reduce the likelihood of provoking symptom episodes. Several mood monitoring tools exist and are readily available for patients to use as part of their regular homework (see Basco & Rush, 2007; Reiser et al., 2017; Sachs & Cosgrove, 1998). Reiser et al. (2017) astutely noted that bipolar patients may view any fluctuations in their mood with undue alarm and, therefore, that patients should be counseled to recognize the normality of mood variability for anyone. To that end, Reiser et al. provided a monitoring chart that incorporates a range of normal mood that they dub the “comfort zone.” At the same time, it is a good idea for bipolar patients to use their mood charting to flag signs that they associate with straying from the comfort zone so that they can implement self-help skills and enlist the assistance of professionals and people in their personal life in a prompt, preventative fashion. Although it is important to be vigilant for prodromal signs of hypomania and mania to be able to enact CBT and/or pharmacologic interventions promptly, it is also important for people to be able to enjoy an improved state of mind without necessarily being in an ever-present state of high alert, the likes of which can be excessively stressful and can reduce quality of life (Mansell et al., 2007). Toward the goal of allowing a respite from this sort of hypervigilant selfmonitoring, it is useful for patients to take stock of the differences between signs of “normal good mood” and prodromal signs of being too high. This inventory can be taken in session with the therapist assisting the process and/ or can be done or completed for homework. The following are examples of some responses about this matter from bipolar patients, including some of their ideas about how to reassure concerned others:
216 Cory F. Newman
• “When my mood is good, but normal, I can sit and read. I feel contented, and I don’t have to get up every couple of minutes to do something, and I don’t get distracted from what I’m reading. I don’t mind the quiet time, and I don’t get bored (if what I’m reading is interesting). I have noticed that my wife likes it when I sit and read for a stretch of time. She thinks it’s a signal that I’m doing well.” • “I know that my mood is in a good zone when I want to be social, but I don’t feel pressure to talk all the time, and I can focus on what other people are saying without feeling the need to interrupt or talk about myself. In fact, I make it a point to be a good listener. This tells me I am okay. Also, other people don’t get annoyed with me.” • “Sleep is important. If I am getting hypomanic, I can’t sleep or I don’t want to sleep. When I’m in a good mood but I can get a full night’s sleep, then I know I’m in a safe range, and I can trust myself to function properly.” • “If somebody tells me they think I’m getting manic I sometimes feel a little annoyed, but if I can reply calmly and not get angry, then this is a good sign that tells me that my mood is normal because I’m not overreacting to someone showing concern for me.” • “Sometimes if I joke around too much, or if I’m busy doing too many things at all hours, it worries my parents, and it can make we wonder about my mood as well. However, if I can hold a calm, serious conversation, and if I’m willing to slow down and take a break from my activities to get some rest, this usually shows me (and my parents) that I’m still in the ‘normal zone.’” Through self-monitoring, patients can determine from a position of strength (i.e., on their own volition and via their own observations) that they may be becoming hypomanic or manic, rather than always being on the receiving end of corrective feedback, which can be disconcerting.
Behavioral Activation and Behavioral Moderation The typical symptoms of unipolar depression—dysphoria, anhedonia, lethargy, sleep disruptions, difficulties with concentration, feelings of guilt and worthlessness, thoughts about suicide, and others—are difficult enough to manage when the “war on mood disorder” is only on one front. In the case of bipolar depression, there is the added challenge of helping the patients boost their mood and activity level without adding undue risk of overshooting the mark and inadvertently potentiating a hypomanic or manic episode. An important intervention for depression is behavioral activation (e.g., Dimidjian et al., 2011). Motivating depressed patients to take part in more of the activities of everyday life is a worthy goal, as success leads to greater self-efficacy, better maintenance of life tasks (which potentially prevents problems), and improved chances of experiencing naturally occurring positive reinforcement.
Bipolar Disorder 217
However, in the case of bipolar disorder, patients who increase their levels of activity may run the risk of becoming overly involved in the pursuit of goals (perhaps staying up late at night in the process), a factor that has been linked to hypomania and mania (S. L. Johnson et al., 2012). Thus, therapists try to engage their patients in a collaborative effort to plan and take part in constructive and/or rewarding tasks in a careful, gradual, and methodical fashion. For example, more than simply scheduling things to do for the coming week, patients also must commit to adhering to a healthy sleep-wake cycle. A college student with bipolar disorder who had been missing classes, avoiding spending time with peers, not working on academic assignments, and not getting exercise would certainly be making progress if they started to do all of these things— but not if they began staying up until all hours of the night in the process, as this would increase the risk of “switching” to a high phase. Behavioral activation remains a central part of helping those with bipolar depression be more effective in the tasks of living, connecting with others, feeling a sense of healthy self-confidence, and experiencing enjoyment. However, therapists must provide the patients with psychoeducation about the importance of moderation and maintenance of sleep hygiene. This may be a “hard sell” to patients who are concerned about the productive time they have lost while depressed and who reason to themselves that they need to “make up for lost time” by going into hyperdrive when they are feeling good. The starting point for therapists is to express understanding of these patients’ position. Empathy is important under any circumstance, but especially so when therapists are setting limits or otherwise suggesting a course of action that is not exactly the patients’ top preference. The following represents the sort of comment that can set the right the tone to elicit the most therapeutic collaboration: THERAPIST: I’m glad that your mood is up and that your energy is up too.
It’s good to see. I want you to be able to sustain a healthy positive feeling and productivity level. I don’t blame you for wanting to do as much as you can as soon as you can. I would probably have the same impulse if I were you. But can we talk about how to pace yourself so that you stay in a safe, healthy zone? With your help and with a good plan, I think we can find a way to prevent going too far and incurring risk. It is okay to try to compensate for lost time, but it would be really wise not to overcompensate. What can be done when the bipolar patient is depressed and is underactive? An initial step is to identify the activities the patient has previously favored (or would like to incorporate) that create a sense of accomplishment or enjoyment (also described as “mastery” and “pleasure”). Patients who are currently depressed may not be optimistic about their ability to summon up the energy to do things for accomplishment, and they may not expect to feel a sense of enjoyment, but they may be willing to begin the process by describing their past interests. Compiling such a list can lead to the therapist encouraging the
218 Cory F. Newman
patient to choose a starting point, as a behavioral experiment to see if the chosen activity creates an incrementally positive effect. A related method is to help patients plan to “chain” behaviors together so that they can get themselves to start their day one action at a time, starting with basic self-care activities such as eating something, getting washed and dressed, and going outside (for exercise, a chore, or going to school or work). At times, patients will be unimpressed, downplaying the significance of such seemingly mundane aspects of functioning. Again, the therapist expresses empathy, emphasizing that quality of life clearly involves more than just getting “up and out” in the morning but also noting that it takes a great deal of fortitude to do this when depressive symptoms dominate. Therapists encourage any good-faith attempts patients make to increase their activity level. Even when the patients have difficulty in starting, the fact that a list has been generated provides ideas for what to do if the patients begin to feel a little better. On the other hand, when patients are in an “up” phase, therapists help patients moderate their participation in the activities for accomplishment and enjoyment. Therapists can present the idea that sometimes showing “mastery” means being the “master of one’s impulses.” This refers to knowing when to refrain from going too far in such activities as shopping, exercising, partying, engaging in hobbies and projects at the expense of sleep, and other potential excesses. The Daily Activity Schedule (DAS; see J. S. Beck, 2011) is a form that patients can use to chart how they use their time (hour-by-hour, day-by-day). The DAS can be used retroactively (i.e., writing what they have already done) or prospectively (i.e., planning how to use their upcoming time). When used retroactively, the DAS can provide clues about how the patients can make better use of their time going forward. When a patient is becoming hyperactive and the DAS indicates that the patient is overbooked to the point of risk, the therapist can ask the patient to choose “10% of the activities that are the lowest priority” and to experiment with replacing those activities with more relaxation and sleep (Newman et al., 2001). Aside from reducing the quantity of activities in which a potentially hypomanic patient may be engaging, another way to safeguard against extremity is to emphasize the importance of the “simple pleasures” of life. Rather than going for high-stimulation activities that pose risks (e.g., drinking at a party, going to a casino, making a major purchase), therapists can help patients consider activities that create a sense of quiet satisfaction and peacefulness. Such activities may include reading, speaking with friends, watching a movie, taking a walk (perhaps with their dog or with an important person), playing music, working on an uncomplicated household project, engaging in a hobby—anything that can be done without too much effort and that brings about a pleasant feeling. Understanding the Consequences of Hypomanic and Manic Behavior As Jamison (1995) noted in her classic memoir, An Unquiet Mind, feeling the high of hypomania and mania is very seductive. Jamison reflected on the days
Bipolar Disorder 219
when she felt on top of the world, able to use her mind and her charms to their maximum power. What brought her back to stark reality was the downside: the inevitable depressive crash and the negative consequences wrought by risky and otherwise extreme behaviors enacted while “high.” Jamison noted that this hard-earned experience can be valuable in terms of preventing future consequences. When patients give indications that they are not being suitably vigilant in guarding against hypomania and mania, such as by skimping on hours of sleep, being a bit laissez-faire about taking their medications, and speaking fondly about being euphoric and energetic, therapists can empathize first, but then ask some important questions (adapted from Newman et al., 2001): 1. How would you describe yourself when you were in a hypomanic or manic episode? What are some things you did during those times that you would choose not to do now? 2. In your experience, how much does your excessively high mood convince you that everything is fine, even when everything is not fine? 3. Knowing what you know now, what sorts of precautions would you be willing to take to limit the risks of being high from this point forward? What are some of the valuable lessons you have learned from your personal experiences with hypomania and mania, and how can you apply those lessons now? When asking such questions, it is important to have a respectful tone because the topic can potentially be shaming. It is also helpful to acknowledge that the experiences of hypomania and mania can be very difficult to resist; therefore, it is important to focus ahead of time on the downsides of these phenomena (e.g., negative consequences) to serve as a motivating force for adhering to limits and striving for moderation in all things. Testing the Functionality of Hyperpositive Thoughts There is an extensive literature on the application of the methods of cognitive restructuring to modify negative thoughts and beliefs (including schemas) that contribute to excessive emotional distress (e.g., J. S. Beck, 2011; Newman, 2015). These same methods can be applied to hyperpositive thoughts (see Lam, Wright, & Sham, 2005; Newman et al., 2001) with the goals being to maximize the skill of “reality testing” and to prevent the sorts of impulsive actions associated with unrealistic optimism and exuberance. The goal is not to discourage, restrict, control, doubt, or demean the patients, though some patients may construe the intervention this way. Again, therapists should be very collaborative and respectful, emphasizing that supporting the patient’s autonomy is a priority, in the context of developing well-practiced skills for keeping themselves in check.

What are some of the signs that a patient’s thoughts are dysfunctionally positive? The following is a brief list of some informal categories of such thoughts, each with an accompanying example: 1. Overestimating one’s capabilities. A tip-off is when patients describe goals that blatantly exceed their credentials, training, experience, and/or aptitude, but they lack the insight to see the implausibility of the outcomes they seek. For example, a young man who had just begun a martial arts class for beginners enthusiastically predicted that he could become the “sensei of [his] own dojo” in a couple of years. 2. Overreliance on luck. This hyperpositive distortion is often manifested by the patient who is neglecting to actively solve problems and/or meet responsibilities, but maintains an attitude that “it will all work out somehow.” Such patients demonstrate insufficient concern about consequences and are more focused on having a good time in the moment than on taking care of important matters that need attention. The people in this patient’s life often get the sense that they are “in denial.” For example, a patient was convinced that he could continue an illicit affair without being discovered, without having to make difficult choices, and without any emotional drama. Thus, he was disinclined to make any changes in his behavior, as he was content with the status quo, believing that it could continue indefinitely, entirely in his control. 3. Overvaluing of immediate gratification. This characteristic of thinking is associated with impulsivity, low frustration tolerance, and an exaggerated sense of urgency in doing something for pleasure. One patient enacted this in the therapy session itself, as she wanted to talk about the Academy Awards (which she had watched on television the night before) rather than focus on a therapeutic agenda. She felt strongly that she should obey her feelings on the matter (i.e., to not discuss appropriate clinical topics) and that she would be “untrue to [herself]” if she had to talk about “something less interesting.” Therapists who detect such hyperpositive thinking in their patients must find a way to address this cognitive problem while still communicating a willingness to understand the patient’s points of view. Therapists have to point out inconvenient truths in a respectful, caring way, without sounding judgmental or authoritarian. One therapist appealed to her patient’s better judgment by saying, “It’s great to be confident, but it’s risky to be overconfident. Knowing where the line between confidence and overconfidence lies requires great wisdom, patience, and humility. I have faith in you that you will exercise wisdom, patience, and humility right now, which means resisting acting on impulse and being willing to get feedback from others.” In terms of helping patients with bipolar depression rationally respond to their excessively hopeless and self-reproachful thoughts, the general literature on CBT interventions for unipolar depression is applicable (e.g., A. T. Beck et
Bipolar Disorder 221
al., 1979; Moore & Garland, 2003). What may be added is a special emphasis on patients’ pessimistic thoughts about ever being able to manage and/or overcome the bipolar illness itself, as well as the patients’ self-condemning or shameinducing beliefs about having the illness in the first place. The sections in this chapter on suicide risk and stigma will touch upon these issues and offer suggests for intervention. Consulting With Trusted Others When patients experience flights of ideas, high energy, and extreme optimism, they often believe that they can do as they wish without having to get feedback from others about the advisability of their plans. In some instances—especially those in which the patient’s family members are alarmed by the patient’s behavior and try to assert control—these patients will do all they can to reassert their autonomy by doing as they please, confident that they are right and that things will work out well. This often leads to a power struggle, thus adding relational discord into the mix, which is distressing for all parties. Therapists can play an important role by helping patients see the merits in communicating openly with trusted others, asking for their feedback, and trying to be collaborative. Toward that end, the therapist can introduce the concept of the two-person feedback principle (Newman et al., 2001). During times when the patient is euthymic, the therapist and patient identify the people in the patient’s life whose judgment and/or counsel are trusted the most. The therapist and patient reach an agreement to utilize these people’s opinions as a safeguard whenever there is reason to believe that the patient is heading toward hypomania or mania. If the patient is married, it is often a good idea to encourage the patient to include the spouse on this “short list,” provided that the spouse is well meaning and responsible. If the patient professes to being solitary most of the time, it is okay if the therapist suggests that they, themselves, should be on this list, provided that someone else is added as well (e.g., a cohort from a support group that the patient has been attending). The patient does not necessarily have to ask others the question “Do you think I’m becoming manic?” It will suffice if patients ask for feedback about their ideas, plans, or decision making. For example, a patient may suddenly wish to buy a new car. Rather than simply acting on their own impulse, the patient can ask at least two other trusted people if they think this sounds like a reasonable idea. An important aspect of this technique is to present it in such a way that it helps the patient “save face.” Therapists do not want to imply that the patients are incapable of making their own choices or that they need a “watchdog.” Instead, this method is presented as a way for patients to illustrate to the important people in their life that they are capable of being careful and thoughtful and as a way to honor others by soliciting their opinions on important matters. Therapists can note that people who are accomplished and influential often hire consultants precisely because it is smart to do so, given that an
222 Cory F. Newman
individual cannot know everything. It is best to surround oneself with people whose judgment is trustworthy. Another benefit of consulting with at least two people is that it takes some time to enact and, therefore, serves as an anti-impulsivity technique. Anything that puts some time and distance between an impulse and acting on that impulse can help prevent patients from making important mistakes in decision making. Sometimes patients take umbrage at the idea that they are not supposed to be “spontaneous” or “trust their own judgment.” Therapists should reframe the matter, noting that the most rewarding acts of spontaneity are typically free of potential negative consequences, and that mastering one’s own impulses represents a high level of well-functioning (e.g., “The highest form of control is self-control”). Improving Interpersonal Functioning Having a good social support system helps patients with serious mood disorders have a higher quality of life and to reduce the risk of suicide (Jamison, 1999; S. L. Johnson et al., 1999). In bipolar disorder, patients’ interpersonal relationships tend to suffer when they self-isolate during periods of dysphoria and/or when they act out during manic episodes in ways that alienate others. Thus, it is common for a CBT agenda with such patients to include interpersonal problem solving, in which patients learn to monitor and recognize the need for repairs, improve communication skills, reduce expressions of anger, and affiliate with others within normal limits (i.e., not too little; with appropriate boundaries). When patients are depressed and disinclined to initiate social interactions, they can still make it a point to be receptive to social invitations and to test their hypotheses that they are “horrible company” or that they will “have a miserable time anyway.” When they are feeling too high, patients can be encouraged to practice self-restraint in what they say and how they act toward others, with the goals of respecting others’ boundaries and being the “master of their impulses.” Therapists teach their patients that effective communication starts with listening, which makes one a better companion for conversation, reduces pressured speech, and improves empathy for the other person. One could argue that training in listening is naturally embedded in a therapy session that includes such fundamental CBT components as summary statements (e.g., when patients are asked to restate the main points that they are taking away from the session) and in giving and receiving feedback. To teach communication skills more broadly, therapists serve as role models for making comments that are thoughtful, tactful, and on topic. Therapists respectfully try to “shape” their patients into speaking in ways that others will find pleasant and congenial, such as steering clear of profanities, making requests instead of complaints, keeping one’s tone of voice moderated, and avoiding being verbose (see Newman, 2005). Of course, the therapeutic relationship itself is a testing ground for the patient’s interpersonal behavior, and the therapist has to be a tactful pur-
Bipolar Disorder 223
veyor of feedback and humble suggestions when patients are acting overly gregarious or familiar toward the therapist or expressing excessive negativity (e.g., insults or sarcastic comments directed at the therapist).
SPECIAL CONSIDERATIONS WITH BIPOLAR SPECTRUM ILLNESS Bipolar illness often poses special challenges for patients as well as their families and practitioners. Some of these challenges include (but are not limited to) the following: (a) difficulties with adherence to pharmacotherapy, (b) risk of suicide, (c) family stressors (both as a triggering factor and as a consequence of the patient’s psychological problems), (d) proper diagnosis and treatment of bipolar disorder in very young patients, and (e) stigma, all of which are described in more detail below. Difficulties With Adherence to Pharmacotherapy Although there is great promise in the use of CBT to improve the functioning and quality of life in bipolar sufferers, the standard of care still customarily necessitates pharmacotherapy. Those cognitive behavioral therapists who are not licensed prescribers themselves generally have to work in tandem with the practitioners who are in charge of their shared bipolar patients’ medication regimens. Although the use of CBT may seem to run parallel to the pharmacotherapy part of treatment, there are important points of overlap. These include the therapist’s need to be aware of the patient’s medication-taking habits (especially if these habits are inconsistent or otherwise maladaptive), the importance of the therapist being empathic about the patient’s fears and misgivings about their medications, and the therapist helping their patient to identify and modify their negative beliefs about medication that may be impeding their adherence to a pharmacotherapy plan. A number of studies have provided evidence that bipolar patients who receive CBT tend to adhere to their medication regimen significantly more than those who do not (e.g., Cochran, 1984; Lam et al., 2000; Scott et al., 2001). Even when patients with bipolar disorder take their medications faithfully, they may still experience low-level symptoms or symptom breakthrough (Solomon et al., 1995). This can be quite discouraging and even demoralizing for patients, and cognitive behavioral therapists have to be able to communicate empathic understanding. Similarly, pharmacotherapy typically comes with side effects, and although the hope is that side effects gradually subside as therapeutic benefits take effect, the reality is not always this straightforward. Further, patients may be on medications that interact in complex ways, such as when a patient needs to be on a diuretic, which can potentially have a problematic impact on the blood levels of the bipolar medication(s). Some patients react to these complications by wanting to abandon their use of the medication(s) for their bipolar illness. This is where therapists have to be able to demonstrate
224 Cory F. Newman
empathy and support while still taking a problem-solving approach that supports the pharmacotherapy in an improved way (in collaboration with whomever is prescribing). CBT has a particularly important role to play with regard to patients’ beliefs about medications, some of which contradict objective findings and/or unnecessarily discourage patients. In order to address such beliefs—the likes of which many patients spontaneously articulate—therapists must try to facilitate a mutually respectful dialogue. This starts with the therapist empathically summarizing the patient’s position as a prelude to offering their own. Let us look at how a therapist might address a number of such problematic beliefs by offering support, validation, reframing, and psychoeducation:
BELIEF: “Medications will turn me into someone I am not. I will lose my true self.”
THERAPIST: It may be true that when you take medications you feel a little
different, especially at the start. It may even feel quite disorienting if your side effects are prominent. On the other hand, if the medication helps prevent extremes in your mood, you may be able to function in the way you normally would, or how you naturally would have functioned if you didn’t have the burden of the bipolar symptoms in the first place. Maybe it is the bipolar illness itself that is robbing you of your true self. Maybe the right medications can help you be the person you were always meant to be if you didn’t have the illness. BELIEF: “Medications will take away my energy and my creative ideas.”
THERAPIST: I believe you when you say that your best creative work is done
with the burst of energy you get when you’re hypomanic, and that you value this. I agree that it is important for you to be able to be productive and imaginative in your work, and I think this is a strength of yours. I can understand why you might be reluctant to take any medications that might stabilize your mood, especially if you equate “stable” with “average,” which you most certainly are not. What I’m thinking about is all the valuable time you’ve lost to your depressive episodes, and how you almost completed a suicide last year, which would have ended all your creative ideas once and for all. I would like to work with you to find a way to minimize risk—and that means doing both CBT and pharmacotherapy—while still supporting your creative
Bipolar Disorder 225
work in any safe way we can. Kay Redfield Jamison is a great role model for this. Remember her book An Unquiet Mind? She admits that when she’s on her medication she doesn’t read as fast, but her books are beautifully written and quite compelling nonetheless. Similarly, I think it is possible for you to take medication and still have great ideas and do great work. Are you willing to see for yourself? BELIEF: “Medications are only needed when I’m sick. I feel fine, so I don’t need them.”
THERAPIST: You’ve been great about taking your medications while you
were so depressed, and you’ve been very patient about waiting until your mood lifted. Now that you’re feeling somewhat better, you’re hoping to get off the medication and move on with your life. I get it, and I wish you could do that. You’ve worked so hard in therapy to get to this point. It would be a terrible thing if you suffered a setback, and I’m concerned that going off your medication would invite this outcome. You’re feeling fine now, and that’s great. You’ve reached a sort of “cruising altitude,” and staying the course seems like the safest thing to do. I’m worried about what might happen if you change the flight plan right now. Can we talk more about this? BELIEF: “Being told to take my medications is inherently demeaning and disrespectful.”
THERAPIST: I agree with you that some people sarcastically use the phrase
“You need to go take your pills” as a gratuitous insult. I know it’s used that way, and it’s wrong. It shows incivility and ignorance on the part of the person saying it. So if that’s the way you perceive being instructed to partake in pharmacotherapy by me, or your psychiatrist, or by somebody in your family, I can understand why you feel indignant. I would too if I were you. However, can we consider the possibility that sometimes being advised to take medication is part of a well-meaning, respectful recommendation, and that it comes from a place of good intentions combined with experience and knowledge?
BELIEF: “I could become addicted to my medications. Thus, I should avoid them.”
226 Cory F. Newman
THERAPIST: The issue of inadvertent addiction to a prescribed medication is
important and timely, and I’m glad you’re aware enough to inquire about it. You’re partially correct that your body adapts gradually to the sorts of medications you are taking and that you can’t just “get off” the medications when you want to make a change. You have to wean off carefully, under supervision. That looks suspiciously like an “addiction,” but actually it’s not. The medications you’re taking are not fast-acting, they don’t give you a “buzz,” and you’ll never develop cravings for them. Yes, there are medications that fit this description of “potentially addictive,” but the medications you’re being prescribed do not. But I appreciate your awareness of this matter, and it’s good that you brought up your concern. You’re asking good questions and being a good advocate for yourself, and I respect that. When patients express concerns, fears, and antipathy toward pharmacotherapy—whether based on maladaptive beliefs or hard experience or a combination of the two—it is imperative that therapists offer compassion and respect. Though pharmacotherapy is customarily an essential part of best practices for the most hopeful outcomes, it can bring side effects and long-term worries that would be daunting for anyone. If practitioners find themselves growing a bit exasperated by their patients who are inconsistent in (or downright avoidant of) taking their medication, they would do well to consider the following hypothetical questions to ask of themselves: “Would I ever volunteer to take the medications my patients are taking?,” “How would I feel about taking such medications for years and decades?” A sober answer to these questions may raise our level of understanding. Similarly, clinicians would do well to understand the appeal of hypomanic and manic states, as some patients with bipolar illness state that the feelings of energy, euphoria, and personal empowerment— however fleeting—are the most redeeming aspects of having the disorder. Thus, they are loath to volunteer to give up these extremely positive feelings through treatment. Therapists do respond by pointing out the negative consequences, including the crushing depressive states that typically follow soon enough, but they must also acknowledge that it is difficult to walk away from peak experiences. Ultimately, one of the idealistic goals of therapy is to help patients find joy and meaning in their lives amid the stability. Risk of Suicide The risk of suicide in the population of sufferers of bipolar disorder is substantial, with an estimated 15% to 19% ultimately completing suicide (Goodwin & Jamison, 2007; Simpson & Jamison, 1999; Strakowski, 2014). Clinicians need to be alert for this risk, assessing their bipolar patients’ thoughts about life and death as a routine part of treatment. The field of CBT has developed robust, brief interventions and safety-planning methods for suicidal patients and thus
Bipolar Disorder 227
is well-positioned to provide care that offers safeguards for those with bipolar disorder (e.g., Brown et al., 2005; Stanley & Brown, 2012; Wenzel et al., 2009). It is good practice to utilize self-report measures (e.g., Beck Depression Inventory-II; A. T. Beck et al., 1996) on a routine basis so that negative changes in the patient’s mood and ideation can be monitored. The issue of hopelessness often is central to a patient’s risk for suicide (A. T. Beck et al., 1990, 1993, 1985), such as when patients maintain the belief that no matter what they do they are always going to suffer (so they might as well end things now). A similar cognitive concept related to the risk of suicide in bipolar patients has to do with feeling defeated and entrapped by an immutable illness (Owen et al., 2018). In such cases, therapists have to navigate a dialectic of validating the patient’s feelings and opinions about having a chronic disorder, while promoting the idea that adhering to treatment and learning self-help skills can in fact lead to significant improvements in one’s life (Newman, 2005). Patients sometimes lament that they are afraid to be hopeful, lest they set themselves up for having their hopes dashed yet again by another virulent symptom episode. They may view suicide as a way to “cut their losses.” The therapist’s task is to cite the current moment as a potential positive turning point if the patient can invest in and commit to treatment. The therapist can add that far from cutting their losses, patients who die prematurely by their own hand may in fact be forfeiting future improvements. The therapist must communicate empathy for the patient’s fears about being hopeful and acknowledge that it is unwise to have blind optimism. However, it is also a set-up for a self-fulfilling prophecy of misery if one only thinks about the downside of life and does not consider the possibility that working collaboratively in treatment can lead to a higher quality of life—one that is worth living. Cognitive behavioral therapists help their deeply depressed and suicidal patients with bipolar disorder construct rational responses to their “suicidogenic beliefs” (Newman, 2018). Three of such beliefs are outlined below, each followed by a sample rational response in brackets: 1. Suicide is the solution to end all problems. [Actually, suicide is the problem to end all solutions, and the problems will only be passed down to others I care about. If I stay alive, I can possibly work to solve some of my problems.] 2. I am a burden to others, and they would be better off if I killed myself. [Actually, the biggest burden to others would be if I killed myself, and that could never be fixed. If I want to be less of a “burden,” I can show that I care about others by working hard in therapy so I can bring something more positive to their lives. And who says I’m a “burden”? That may be my own self-criticism talking. There is plenty of evidence that others care and that I can do some good things.] 3. The pain of bipolar disorder is too much to bear, and the only way to end the pain is to die. [This feels so true, but I also remember what it’s like to feel joyful and enthusiastic, and I want that experience again, but first I have to live.]
228 Cory F. Newman
A sense of social isolation exacerbates the patient’s depression, and, therefore, therapists try to help their patients to seek social support. In fact, this is a standard part of safety planning in CBT (see Stanley & Brown, 2012). When friends are in short supply, and/or the patient’s family members are feeling depleted, therapists can assist their patients in finding and attending support groups via their local chapters of the National Alliance on Mental Illness (NAMI, https://www.nami.org) or the Depression and Bipolar Support Alliance (DBSA, https://www.dballiance.org), among other organizations. Bipolar Disorder and the Family “Bipolar disorder and its treatment frequently are family affairs” (Newman et al., 2001, p. 137). Fundamentally, there is a significant hereditary component to bipolar disorder, and, thus, it is quite common for bipolar patients to have family members who are also on the bipolar spectrum (Algorta et al., 2015). Individuals who suffer bouts of mood swings and other extreme symptoms also affect the lives of their family members, especially those with whom they reside. In like fashion, the individual’s treatment can be influenced (for better or worse) by the actions of their loved ones. The ways in which individuals with bipolar disorder and their close relations interact in characteristic patterns of communication and interpersonal control can exert an influence on the individuals’ episodes of relapse and recovery (S. L. Johnson et al., 2016; Miklowitz, 2008; Miklowitz et al., 1996). A thorough assessment necessarily involves inquiring about the role of the family relationships in the patient’s life, and the treatment plan can include family members in one or more of the patient’s therapy sessions. Cognitive behavioral practitioners are mindful of the hardships that bipolar patients and their families suffer, and they come ready to be explicitly empathic to all parties. For example, a bipolar patient may feel criticized, blamed, stigmatized, patronized, overcontrolled, and perhaps rejected by one or more family members. For their part, the family members may experience the stress of worrying about their loved one with bipolar illness being at risk for engaging in destructively impulsive behavior, including suicide. Family members often report that they have had to contend with such significant problems as the patient’s unwise monetary expenditures, risky behaviors (including those that put the household and its inhabitants in harm’s way), infidelities, neglect of responsibilities, legal involvements (e.g., stemming from illicit drug use and/or traffic mishaps), and at times abusive behavior, to name a few problems. In a conjoint couple or family session, therapists often must manage one or more parties’ anger, extreme worries, and/or hopelessness, and they must do so in a way that keeps order and structure in the session whilst still offering support and concrete suggestions for intervention. Families that are high in “expressed emotion” (EE; see S. L. Johnson et al., 2016; Miklowitz et al., 1996) are most often those who present in the manner described above. EE is a term that was originally coined in research on families
Bipolar Disorder 229
of persons diagnosed with schizophrenia (see Kavanagh, 1992), but it has been appropriated for use in the study of the families of bipolar disorder. It refers to high levels of negativity and criticism, both emanating from and coming toward the identified patient in typically vicious cycles. Low-EE families have their tensions as well, but their interactions tend not to be characterized by attacks and counterattacks. In any event, assessment of the family’s communication style and intervening therein is central to doing family work with bipolar patients. Expressions of blame and shame need to be identified and modified. Similarly, malevolent interpretations of intent must become targets for intervention (e.g., when both the bipolar patient and their family members believe the other is deliberately trying to ruin their lives, when in fact they are all scrambling to survive the best way they know how). Communication skills training and modification of attributions are central components in working effectively with families, but these interventions are further assisted when the clinician takes the time to listen to and understand the unique hardships facing the patients and their families. To borrow from Leo Tolstoy, unhappy families are unhappy in their own way. Bipolar Disorder in Very Young Patients There is evidence that the first signs of bipolar disorder often occur in childhood and adolescence, and that early detection and early intervention are of key importance in outcome for sufferers and their families (Youngstrom & Algorta, 2014). The occurrence of a manic episode is required for the diagnosis of bipolar I disorder; however, there are challenges in identifying mania in children and adolescents, where factors surrounding cognitive and emotional development can cloud the assessment (e.g., when is “grandiosity” simply a matter of inexperience or immaturity rather than frank dysfunction?). Though it is difficult to apply the strict definition of mania as noted in adults to the assessment of children and adolescents, it is possible to flag symptoms such as chronic mood lability, agitation, and irritability as potential signs of a developing bipolar illness. Coincidentally, these are also signs of attention-deficit/hyperactivity disorder (ADHD) and pediatric depression (Strakowski, 2014). Therefore, differential diagnosis poses difficulties, made more complicated by the fact that ADHD and bipolar disorder can co-occur in children and adolescents (Pavuluri & May, 2014). Unfortunately, there are significant risks involved in providing pharmacotherapy for the “wrong” clinical problem. For the child or adolescent with bipolar illness who is inadvertently identified as having ADHD, a prescribed stimulant can induce manic symptoms. Conversely, the child or adolescent with ADHD who is given a bipolar diagnosis may needlessly take mood stabilizing medication(s) that are not ideal for neurodevelopment (i.e., cannot be taken under the age of 10), to be taken only when not taking them would lead to more unfavorable outcomes. To minimize errors, it is advised to look for distinguishing features of mania (e.g., decreased need for sleep, episodic presentation) combined with a family history of bipolar disorder (Strakowski, 2014; Youngstrom et al., 2010).
230 Cory F. Newman
Given that children and adolescents are very sensitive to side effects from medications that are approved for the treatment of bipolar disorder (e.g., weight gain, sedation, cognitive impairment), the use of psychosocial treatments that involve the family and that teach the skills of mood charting and self-reflecting before taking action are of critical importance. A prime example is the RAINBOW program (West et al., 2017), a 12-session child-and-family-focused CBT intervention (CFF-CBT) for children on the bipolar spectrum that involves intensive work with the parents in parallel to the work with the children. This treatment program fits the interventions to the developmental level of the child and the unique needs of the family, offers psychoeducation and communication skills training, and identifies itself as a combination of CBT and interpersonal therapy. Combating Shame and Stigma Manic episodes, in particular, can induce people to engage in behaviors that they would ordinarily exercise discretion to avoid if they were in a more stable state of mood and mind. Looking back over negative consequences incurred as a result of impulsive, risky, and otherwise undercontrolled behavior can cause shame and regret. As Jamison (1995) noted, even when it is difficult to remember what one has done while in manic states, the inevitable depressions that follow include the challenge of dealing with the consequences, which may include damaged relationships, work projects that have been started and abandoned, bills that have accumulated, and other results that exacerbate selfreproach. One of the delicate balances that therapists must maintain is the ability to support patients in their efforts to take ownership of their decisions and actions, while dissuading them from punishing and no longer caring about themselves owing to their earlier problematic decisions and actions. In addition to self-blame, persons with bipolar illness may face the prospect of discrimination in terms of housing and employment (Corrigan, 1998), as well as medical advice about their fitness to become parents (Jamison, 1995). Of course, in our present time, the looming threat of bipolar disorder as a “preexisting condition” that may impede access to health insurance is also a matter of great concern. In recent times, we have also seen more people in the public eye (e.g., actors, musicians) come forward with their stories about dealing with bipolar illness, and this development has served an important educational and potentially destigmatizing function in society. However, much remains to be done in order to overcome the stigmatization that still exists. Perhaps the area in which patients and their therapists have the best chance of making a positive impact on stigma is in overcoming self-stigma. Bipolar sufferers sometimes blame themselves for their illness, an internal attribution that serves as a counterproductive self-condemnation. Therapists can help their patients to modify this view by taking a more constructive stance. This is typified by endorsing the belief that while the bipolar illness itself is not directly in the patient’s control, the positive steps that can be taken to effectively manage

the bipolar illness are at least partly in the patient’s control. Therapists give their patients much positive reinforcement for their active participation in treatment, including adhering to their pharmacotherapy as best they can, doing their CBT homework, maintaining stability in their personal schedules and sleep-wake cycles, and self-monitoring their depressive and/or hyperpositive thought processes for prompt modification, among others. Therapists need to keep their antennae up for patients’ self-stigmatizing statements such as “I’m just weird and crazy,” “I’m hopeless and useless,” and “I’m a burden to everyone.” These self-stigmatic beliefs immediately become targets for intervention in session and for homework. In summary, although it may be a difficult, long haul to change societal attitudes toward mental illness (though still a most worthy goal), we see that it is perhaps more doable to work on reducing stigma from the inside out (Newman et al., 2001). CBT inherently helps with this goal by focusing on objective assessment and skills acquisition, rather than on labeling and blaming (Lam et al., 1999). Additionally, CBT helps patients build on their personal strengths, including their talents, social support systems, and examples of successful coping. When patients are proud of their writing or artistic skills, therapists can encourage them to make use of these abilities in the service of therapy homework (provided that the patients do not keep themselves up too late at night working on it). Patients have been known to want to show their therapists examples of their creative output, including poetry, articles they have written, artwork and photography, and online links to their performances (e.g., singing in a band, doing stand-up comedy), and it is important for therapists to take an interest. Aside from demonstrating good will, therapists can also work with their patients to derive joy from their creative activities while striving toward improved self-management in areas of their life that require self-regulation and routinization (e.g., reliably getting up in the morning with enough time to get to work without being late; being tactful even when they have an urge to be sarcastic).
EFFICACY Although CBT for bipolar disorder is not necessarily a short-term treatment, most of the relevant studies have utilized a limited number of sessions for practical purposes. In one of the earliest studies, just six sessions of CBT were found to significantly improve patients’ adherence to lithium (21% discontinuing as compared with 57% discontinuing) and to reduce hospitalization rates when compared with pharmacotherapy alone (Cochran, 1984). Another brief CBT intervention (up to 12 sessions) called “relapse prevention” focused heavily on teaching patients to self-assess prodromal signs of bipolar mood episodes. Compared with treatment as usual (TAU), the CBT group had significantly fewer manic relapses (27% vs. 57%), and fewer, shorter hospital stays (Perry et al., 1999). The CBT group also showed higher levels of social functioning and work

performance. In a study of 25 bipolar patients who were experiencing relapses in spite of being on mood stabilizers (Lam et al., 2000), 6 months of CBT was superior to TAU in terms of better adherence to medication, fewer symptom episodes, and improved hopefulness and social functioning. In a CBT trial that also emphasized activity regulation and sleep intervention, 42 patients were randomly assigned to CBT or a 6-month wait-list condition followed by CBT (Scott et al., 2001). Data collected at the 6-month mark and 18-month mark showed that CBT was associated with significant improvements in depressive symptoms, depressive relapse rates, and global adaptational functioning compared with the wait-list control, but manic symptoms showed no significant difference. Scott and colleagues later conducted a multicenter randomized controlled trial (RCT) involving 253 patients with bipolar disorder (Scott et al., 2006), in which 22 sessions of CBT were compared with TAU. Follow-ups were conducted approximately every 8 weeks for 18 months posttermination. Results were mixed in that adjunctive CBT was significantly better than TAU for patients who had relatively fewer previous episodes, but less efficacious in those with higher numbers of prior episodes, leading the authors to posit that CBT may be better viewed as an early treatment option for bipolar disorder. In another significant RCT, CBT with pharmacotherapy was compared with pharmacotherapy alone (Lam et al., 2003). Patients in the CBT condition had access to 12 to 18 sessions within the initial 6-month period and two booster sessions within the next 6-month period. During the first year of follow-up, patients who received CBT had significantly lower relapse rates (44% vs. 75%), fewer days in episode, higher social functioning, and less depression and mania than those receiving pharmacotherapy alone. At the 2-year follow-up mark, the gains made in reducing depressive symptoms held, but reductions in manic symptoms were not maintained (Lam, Hayward, et al., 2005). One interpretation of this finding is that maintenance of therapeutic gains in combatting mania may require more frequent sessions over a longer period of time, and another is that current CBT approaches may be more powerful for depression than for mania (S. L. Johnson & Peckham, 2018). The data from an earlier study also recommended more sessions of CBT even for depressive episodes, with an emphasis on modifying dysfunctional beliefs (Zaretsky et al., 1999). In an open trial, Reilly-Harrington et al. (2007) designed and tested a 20-session CBT protocol (50 minutes per session) designed to tackle one of the most virulent forms of bipolar disorder—rapid-cycling. Using the Newman et al. (2001) text and the Otto et al. (2011) manual, Reilly-Harrington and colleagues adapted the treatment to place emphasis on coping with frequent shifts in mood, as well as managing comorbid conditions (e.g., anxiety disorders). They reported that 6 out of 10 patients completed the program, with the four who dropped out doing so because of practical reasons unrelated to their satisfaction with the treatment. Completers showed improvements in depression, which remained stable through 2 months of follow-up. However, the tendency toward hypomania and mania did not change, and patients’ irregular sleep patterns frequently contributed to difficulties.
Bipolar Disorder 233
Some studies have provided evidence that CBT and other active psychosocial treatment approaches (when used as adjuncts to pharmacotherapy) may achieve comparable results. In a study involving 204 patients, CBT did not differ from a group psychoeducation approach in terms of relapse rates and symptom severity across an 18-month follow-up (Parikh et al., 2012). In another clinical trial involving 120 adults with bipolar I disorder, structured psychoeducation sessions were found to be more efficacious when compared with an unstructured support group or medication alone, resulting in fewer symptom episodes and fewer and shorter inpatient stays, even at a 5-year follow-up (Colom et al., 2009). In yet another study of 76 patients randomly assigned either to CBT or a combination of psychoeducation, supportive therapy, and mood monitoring, relative relapse rates showed no difference (Meyer & Hautzinger, 2012). In a major, multisite, longitudinal RCT called the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), Miklowitz et al. (2007) reviewed the data from 15 clinics, in which the active psychosocial treatments consisted of 50-minute sessions. A group of 163 patients diagnosed with either bipolar I or bipolar II disorder received either CBT, family-focused therapy (FFT; Miklowitz, 2008), or interpersonal social rhythm therapy (IPSRT; Frank et al., 2005); up to 30 sessions over 9 months. Another group of 130 patients received three sessions of “collaborative care” (involving psychoeducational videotapes and instructions), and all 293 patients received pharmacotherapy. Rates of attrition from treatment did not differ significantly across conditions (about a third of the patients left treatment early), and patients receiving CBT, FFT, and IPSRT had significantly higher year-end recovery rates and shorter times to recovery compared with collaborative care. There were no statistically significant differences between CBT, FFT, and IPSRT regarding outcome. Miklowitz et al. (2007) made some important observations about the results of the STEP-BD project, including the assertion that the overall attrition rate was unacceptably high and needed more attention as a target for assessment and intervention in its own right. He added that CBT, FFT, and IPSRT have many shared components in their protocols and that “future studies will combine the most effective components of the modalities and evaluate hybrid models of psychotherapy” (p. 425). Additional findings from the STEP-BD project are noteworthy. Having an extreme attributional cognitive style predicted lower likelihood of recovery (Stange et al., 2013), highlighting the importance of cognitive interventions. Also, subsyndromal depressive symptoms had a significant negative impact on patients (Marangell et al., 2009), suggesting that patients need support even when they are not technically in a symptom episode. Lower total time of sleep and increased sleep variability were associated with greater mood severity (Gruber et al., 2011), emphasizing the role of sleep disruption in the disorder and the utility of improved sleep hygiene. A recent meta-analysis (Chiang et al., 2017) reviewed the data from 19 rigorously conducted RCTs (from the years 2000 to 2015, including some of those mentioned above) in which CBT with pharmacotherapy was compared with “standard care” (often pharmacotherapy alone) in the treatment of both bipolar
234 Cory F. Newman
I and II disorders. The efficacy of CBT in lowering the relapse rate was evaluated from the overall odds ratio (pooled OR = 0.506), on the basis of which the authors concluded that CBT significantly reduced relapse (more so for those with bipolar I rather than bipolar II). Using Hedges’s g to determine the effect sizes of continuous outcomes, the authors concluded that CBT improved depressive symptoms (g = –0.494), lowered the degree of mania severity (g = –0.581), and aided the patients’ psychosocial functioning (g = 0.457), representing mild-to-moderate effect sizes. This outcome was particularly noteworthy in that the meta-analysis included the Scott et al. (2006) study that reported an overall null effect owing to its inclusion of patients with longstanding, refractory bipolar illness. Chiang et al. (2017) also found that the contributory benefits of CBT were enhanced when the sessions were lengthy (90 minutes or more), and they hypothesized that this may be due to the extra attention to the therapeutic relationship that is required in any given session with such patients. One may also hypothesize that getting patients in the depressive phase activated to take part in the session and helping patients in the hypomanic phase to be more focused and on track also requires more time in session. It should be noted that (in general) the treatment studies cited in this chapter indicate that 90-minute sessions are more common in group- and family-based sessions than in individual CBT. In addition to the studies that have found additive effects of CBT on improving functioning and reducing morbidity in patients with bipolar disorder, there have been recent studies (not included in the Chiang et al., 2017 meta-analysis) on CBT and related psychosocial interventions (e.g., mindfulness) aiming for broader goals. The “recovery-oriented” model of treatment seeks to improve patients’ quality of life even as they accept the difficulties that phasic mood instability and cognitive alterations pose over the long term (Jones et al., 2015; Murray et al., 2017). Jones et al. (2015) described the recovery-oriented model as being more flexible than customary CBT manuals for bipolar illness. The recovery-oriented model is based in part on the findings of the STEP-BD multisite study (Miklowitz et al., 2007), suggesting that the major psychosocial models for bipolar treatment (e.g., CBT, IPSRT, FFT) were all found to be superior to TAU, that there was an absence of significant differences in outcomes among them, and that each of them had something of value to offer, perhaps in a complementary fashion. Jones et al. (2015) stated that the goals of treatment are set collaboratively with the patients, the course of treatment is guided by an individualized case conceptualization (e.g., taking into account such factors as comorbid conditions and self-stigmatizing beliefs), and quality of life (e.g., improvement in social functioning) is given relatively more emphasis than a focus on reducing symptoms per se. The patients are free to draw from methods across psychosocial models as they see fit (e.g., going beyond CBT to include interventions from FFT and IPSRT). The Jones et al. (2015) study randomized 67 patients to 18 sessions of recovery-focused CBT or TAU. Although there was no significant difference between the groups with respect to medication adherence, the recovery-focused
Bipolar Disorder 235
CBT group showed significantly increased time to any mood relapse up to 15 months of follow-up. The authors also reported that quality of life and social functioning were improved compared with TAU. There is acknowledgment that bipolar illness—as a longitudinal disorder— presents varying challenges across time. Patients who have suffered the illness through numerous cycles and many years respond differently to treatment than those who present for treatment earlier in the course of the illness (see Scott et al., 2006). In response, the recovery-oriented approach recommends a staging approach to treatment. For example, more time is allowed at the start of treatment to deal explicitly with what it means to the patient to receive the diagnosis of bipolar disorder. Taking time to engage the patient in this manner is not only empathic, it also facilitates patients’ acceptance of the treatment. Another example of a staging approach is the recovery-oriented model’s emphasis on the importance of subsyndromal symptoms (particularly depressive symptoms). This is particularly important in that patients with bipolar illness may feel worn down and demoralized with what they feel to be an ongoing battle with symptoms, even when clinicians might otherwise deem them to be in-between episodes (Samalin et al., 2014). At such times, focusing on maintaining hope and striving to continue to be invested in positive activities are of utmost importance. Additionally, there is evidence that mindfulness-based interventions may have a positive role to play across all stages of bipolar illness (Deckersbach et al., 2014; Miklowitz et al., 2009). Aside from facilitating a general sense of calm, mindfulness methods may also reduce anxiety and improve sleep, adding to quality of life and reducing the risk of provoking hypomania. The recoveryoriented CBT approach above (Jones et al., 2015; Murray et al., 2017) also included mindfulness among its interventions. Another application of a CBT treatment model aimed at reducing comorbid anxiety problems in bipolar disorder is the Unified Protocol (UP; Barlow et al., 2011). In a pilot feasibility and acceptability trial, Ellard et al. (2017) hypothesized that the UP’s focus on common core processes that underlie the full range of anxiety and mood disorders would be advantageous in helping anxious bipolar patients develop general emotional regulation skills. Their results were promising for the reduction of anxiety on the Hamilton-Anxiety Rating Scale (Hamilton, 1959; Cohen’s d = 0.88) and the attenuation of depressive symptoms on the Hamilton-Depression Rating Scale (Hamilton, 1960; Cohen’s d = 0.82), thus meriting further studies. The authors also suggested improvements to the protocol to bolster responsivity in those patients who showed greater difficulties with treatment compliance. As early intervention for bipolar disorder is ideal (Youngstrom & Algorta, 2014), treatment for children and adolescents with the illness takes on added significance. In terms of individual treatment, a manualized cognitive behavioral intervention was tested on a small sample of adolescents with bipolar disorder, half of whom received CBT in addition to pharmacotherapy (Feeny et al., 2006). The authors concluded that the results supported the feasibility and efficacy of the CBT approach as an adjunct to pharmacotherapy. Looking at treatment for
236 Cory F. Newman
children that also includes the family (the RAINBOW program; West et al., 2017), CFF-CBT was found in a randomized trial to result in reductions in patient-reported mania at posttreatment, reductions in patient-reported depression at both posttreatment and follow-up, and improvements in global functioning at follow-up (West et al., 2014). Later, this program was tested in Sweden in a case-series design involving patients from ages 8 to 18 and their families, where multiple families would meet together (Knutsson et al., 2017). The authors stated that this format of CFF-CBT was feasible to deliver in an outpatient setting and that there was evidence that it increased parents’ skills and knowledge for coping, improved the interactions of the family members, and enhanced the psychosocial functioning of the children and adolescents with bipolar disorder. CBT-based approaches in a group format for adults with bipolar disorder also seems to hold promise. In an early study, an open trial in the UK on a small group of four patients with bipolar disorder showed the potential benefits of this format (Palmer et al., 1995). Shortly thereafter, a randomized, controlled study in the United States using group CBT for bipolar disorder supported these findings (Hirshfeld et al., 1998), with longer periods of euthymia in the CBT group maintained at follow-up as well. More recently, in a RCT utilizing 14 sessions of group CBT for bipolar patients (CBT vs. TAU, with all participants receiving pharmacotherapy), those receiving CBT indicated significantly higher quality of life on self-report measures, significantly lower scores on depression, and reduced frequency and duration of symptom episodes (Costa et al., 2012). There have been recent developments in applying and adapting the dialectical behavioral therapy (DBT) group format for use with bipolar populations, based on the idea that patients with bipolar disorder are similar to those with borderline personality disorder in potentially benefiting from emotional selfregulation, mindfulness, and psychological skills training in a supportive, validating environment. For example, van Dijk et al. (2013) conducted a RCT with 26 adults with bipolar I or bipolar II disorder assigned to a DBT-based psychoeducational group, comparing them to patients in a wait-list control group. Those who took part in the DBT group evinced greater mindfulness skills, lower fear of and increased sense of control over emotional states, and fewer emergency department visits and mental health admissions over a 6-month period. Eisner et al. (2017) ran an open trial in which 37 participants with bipolar disorder engaged in a 12-week DBT skills group. Repeated measures for mixed models revealed improved emotional self-regulation, distress tolerance, and improved sense of well-being. Although there is an ever-growing body of literature on the efficacy of psychosocial approaches to the individual treatment of persons with bipolar disorder, the data on family and group approaches to psychological care show that there is indeed strength in numbers.
CONCLUSION AND FUTURE DIRECTIONS Overall, findings for the efficacy of CBT for bipolar disorder have been moderately promising, especially with regard to increasing adherence to pharmaco-
Bipolar Disorder 237
therapy and in the amelioration of depressive symptoms. However, results have been mixed in that there is evidence that patients in later stages of bipolar disorder are less responsive to CBT (Scott et al., 2006), and questions remain about whether CBT is beneficial compared with other active psychosocial treatments (S. L. Johnson & Peckham, 2018). A more hopeful way of looking at the data is that there are several evidence-based psychosocial models of treatment for bipolar disorder that overlap in their approaches but also bring unique strengths that may work well in synergy (see Miklowitz et al., 2007). Treatment manuals, such as Reiser et al. (2017), bring together interventions from CBT, FFT, and IPSRT, and there is evidence that adding mindfulness training can also boost the efficacy of psychosocial approaches to the treatment of bipolar disorder (Deckersbach et al., 2014; Miklowitz et al., 2009). The intent of the recovery-oriented model of CBT (as a whole) is to place more emphasis on tailor-making the treatment to fit the bipolar patient’s stage of illness, to better address the patient’s comorbid problems and individually conceptualize the case, and to go beyond simple reduction of symptoms to improving the patient’s quality of life as the patient defines it. Further developments of psychosocial treatments for bipolar disorder will prioritize this humanistic approach (Murray et al., 2017). It is conceivable that, going forward, this hybridization of psychosocial interventions will be more the norm rather than the exception. Bipolar patients need to learn a plethora of self-help skills for combating dysregulation, which makes them potential candidates for the DBT model in terms of utilizing modules of skills training (e.g., social and circadian rhythm monitoring and routinization; behavioral activation and moderation; pursuit of personally meaningful goals within healthy limits; emotional self-regulation with relaxation and mindfulness; rational responding against hopelessness as well as hyperpositive thinking; making peace with pharmacotherapy; family sessions with communication training). As noted, promising work has been reported in applying DBT to bipolar sufferers (Eisner et al., 2017; van Dijk et al., 2013), and further research and development in this area is highly likely. Self-monitoring takes on added significance in bipolar disorder, as patients reflect on and measure their moods, thought processes, behavioral activities, and sleep-wake cycles. Handy, helpful tools such as phone apps to track and measure these (and other) areas of functioning will become more widely utilized and hopefully standardized (see https://www.healthline.com/health/ bipolar-disorder/top-iphone-android-apps for an up-to-date sampling of digital mood journals, diary cards, skills coaches, medication reminders, etc.). In the near future, one could imagine the further development of personal tracking devices that people wear (e.g., successive generations of Fitbit) that will go beyond monitoring activity levels and sleep patterns to actually provide warning messages, as well as positive reinforcement comments, all of which may be tied (with the patient’s consent) into the electronic records managed by the patient’s healthcare providers. The popularity of apps and personal devices will assist in the dissemination of CBT and other psychosocial treatments for bipolar
238 Cory F. Newman
disorder that emphasize self-monitoring, perhaps ultimately serving as an incentive for persons to seek treatment with mental health professionals when they otherwise may not have done so without the consciousness-raising assist from the apps. A more low-tech (yet high-benefit) method of dissemination of evidencebased treatments for bipolar disorder comes in the form of self-help books based on the treatment methods described in this chapter (e.g., Basco, 2015; Bauer et al., 2009; Miklowitz, 2011; Pavuluri, 2008; Otto et al., 2011; Roberts et al., 2014; van Dijk, 2009), which may be assigned by therapists as part of patients’ homework, and/or recommended to persons whose family members with bipolar illness may be reluctant to commence treatment but who may be willing to read on the subject of self-help. Cross-cultural issues increasingly have been recognized as playing important roles in understanding psychopathology and in crafting treatments to fit the sensibilities of the patients of differing backgrounds (Hays & Iwamasa, 2006). In the case of bipolar disorder, family approaches such as FFT (as well as CBT and IPSRT sessions that include family members) need to adapt communication exercises in a way that is sensitive to the cultural norms of the families. For example, the Western family communication model of making direct eye contact and using “I” statements may be construed as disrespectful if being directed from a younger to an older generation member in a non-Western culture (Ozerdem et al., 2015). Patients and their families from non-Western cultures may be more receptive to acceptance and mindfulness methods as compared with their Western counterparts, who may be more open to rational responding and other active change processes (Miklowitz, 2015). When studying bipolar disorder more broadly in terms of cross-national prevalence, there is evidence that cultures that value and reward individual empowerment and goal pursuit, and that provide rich opportunities for personal achievement, are somewhat “maniatrophic” (see K. R. Johnson & Johnson, 2014) when compared with societies that place more value on collectivism. Understanding such differences will shape future research on bipolar disorder and its treatment on a global level.

Beyond that, it was considered unnecessary to delve into what voices said or what material was contained in the delusions. To do so was a waste of time, as once the presence of hallucinations and/or delusions was established, it was only necessary to determine the presence of other symptoms that would clarify which diagnosis—containing psychosis as a symptom—was correct and, from there, which medications to order. It did not take this author long to question this approach. It was difficult to believe that someone reporting voices telling him to commit suicide was not also experiencing that same urge to do so. Likewise, it seemed that someone with a delusion of being married and having children and a career would also have those same desires.1 A number of years from then, in the mid-1990s, a book called CognitiveBehavioral Therapy for Schizophrenia was published (Kingdon, & Turkington, 1994). British authors David Kingdon and Douglas Turkington (cf., Kingdon & Turkington, 2002) described how the content of voices and delusions are important and are used to facilitate treatment efforts. Cognitive behavioral therapy for psychosis (CBTp) helps clients examine the beliefs associated with their voices and delusions by testing their veracity. Other British clinical research groups and clinicians (Chadwick et al., 1996; Fowler et al., 1995; Morrison, 2002; Morrison et al., 2004; Nelson, 1997; Wykes et al., 1998) were Clinical examples are disguised to protect patient confidentiality.

also developing and testing the use of CBTp. This effort eventually spread throughout the world so that now CBTp is practiced and researched in most nations where CBT for other psychological conditions is utilized. The importance of the content of hallucinations and delusions has become a more acceptable outlook.
CONDITIONS AMENABLE TO CBT FOR PSYCHOSIS Psychosis consists of hallucinations and/or delusions. Some definitions add the positive symptoms of formal thought disorder (FTD) and bizarre behavior, and some even add the negative symptoms (i.e., lack of: motivation [avolition], interest [apathy], socialization [asociality], affect [blunted affect], speech [alogia], and pleasure [anhedonia]). Although commonly viewed as a loss of touch with reality, it is more an addition to reality (hence the term positive symptoms) of nonexistent entities (i.e., voices, images) and/or situations (i.e., being followed or listened to, or being able to read minds). Mostly associated with schizophrenia, psychosis presents in other mental health conditions including brief psychotic disorder, delusional disorder, schizoaffective disorder, major depressive disorder, bipolar disorder, and psychosis due to substance use or medical conditions. CBTp is used for these conditions (though the latter two are better managed by addressing the underlying causes—substance use and medical condition). Research posits that psychosis exists on a continuum from less frequent self-reported attenuated positive symptoms in the general population, to schizotypal traits, to schizotypal personality disorder, and ultimately to fullblown psychosis, which results in the diagnosis of a psychotic disorder (Esterberg & Compton, 2009). Not all instances of psychosis need treatment, but CBTp represents an important part of the collection of treatments available when the person is distressed or functioning suboptimally. CBTp is used in an expanded manner for people with schizophrenia— addressed as well are FTD, bizarre behavior, and negative symptoms. In addition, general CBT can be used when psychosis is in the context of other conditions typically treated using CBT (e.g., major depressive disorder with psychotic features is treated with both CBT for depression and CBTp). For brevity, we use the terms “psychosis” and “CBTp” to mean the conditions and CBT treatments of both psychosis and schizophrenia, keeping in mind that schizophrenia can also include FTD, bizarre behavior, and negative symptoms as well as cognitive deficits (e.g., difficulties with attention, memory, sequencing, etc.). We often refer to treatment of schizophrenia with the understanding that aspects involving psychosis also apply to other psychotic disorders. Although the emphasis here will be on cognitive therapy, we use the acronym CBTp as opposed to CTp, as some techniques presented here use predominantly behavioral approaches. However, behavioral approaches are most beneficial when the cognitive components are considered as well.
Psychosis 249
A BRIEF HISTORY OF THE TREATMENT OF PSYCHOSIS Treatment of psychosis has drastically changed over the centuries (de Chávez, 2009; Colp, 1995). Ancient and medieval treatments, such as blood-letting, trepanation (i.e., drilling holes in the skull to release demons), and exorcisms, were “modernized” by the early 1800s with the use of fever therapy (sometimes induced by purposeful infection), freezing water, sensory deprivation, vomiting therapy, and forms of terror induction (e.g., immobilization, swinging). In the early 1900s, various (often dangerous) treatments such as hydrotherapy, insulin coma therapy, and lobotomies were utilized. Starting in the 1930s, electroconvulsive therapy was added. Medicinal treatment began in 1952 with the introduction of Thorazine. Institutionalization, started in medieval times, continues to this day, but with changes in its detailed nature. Psychotherapy for psychosis can be traced back to ancient Greece with the use of rhetoric and dialogue by philosophers to alter the thinking of those with psychosis (de Chávez, 2009). Formal psychotherapeutic approaches for schizophrenia started in the early 1900s with psychoanalysis, having limited success. Efforts to deinstitutionalize this population began in the 1960s with John F. Kennedy’s Mental Health Act. Psychosocial methods were needed (in addition to the prominent use of medications) in the rehabilitation into society of people with psychosis. The 1960s and 1970s were characterized by social skills training, token economy, and supportive therapy. This was followed, beginning in the late 1980s, by cognitive therapy and cognitive remediation/rehabilitation (which address cognitive deficits). Just as cognitive therapy expanded to include behavioral therapy, CBTp has more recently been expanded to include other modalities of treatment including acceptance and change therapy, compassionfocused therapy, and mindfulness approaches (Wright et al., 2014).
THE USES OF CBTp CBTp is used in the treatment of persons with psychosis in a number of ways. In a modified form (described below in the negative symptoms section), CBT helps with their depression, anxiety, anger, and other emotional distress, much as with any other client. Often, those with psychosis have not been provided with individual therapy addressing their basic concerns related to common emotional reactions. To this day, medication continues to be the mainstay of treatment for those with psychosis, partly due to them being less likely to request therapy than those with primarily emotional issues. This is also due, in part, to providers not being aware of psychotherapeutic treatments for psychosis such as CBTp. When therapy is provided, it is often supportive therapy that does not delve into ways to help them resolve these problems. Psychotherapeutic intervention, especially that of CBT, had not been recognized for decades as a modality for use with persons with psychosis. Once the British groups started
250 Stolar and Wolfe
using CBT to treat psychotic symptoms, the door was opened to use it for emotional problems as well. CBTp can address these issues using a structured, directive approach that is often needed by those with psychosis. CBTp is also used to improve insight about illness by increasing understanding of how symptoms could result from physiological alterations amenable to improvement with the use of medication and therapy. Examining, correcting, and modifying beliefs about one’s condition can be beneficial in many ways, but caution is needed, as it can be detrimental (as elaborated below). Finally, and most prominently, CBTp is useful in treating the individual positive and negative symptoms, as much of this chapter will describe. Together, these uses of CBTp for psychosis improve general, social, and occupational functioning, thus enhancing quality of life.
THE LIMITATIONS OF CBTp CBTp is beneficial to many people with psychosis, but there are limitations in its use and effects. Some persons have symptoms that are too severe to allow meaningful utilization of CBTp (or any psychotherapy, for that matter). If comprehension, attention, memory, language, and/or motivation are severely impaired (due to cognitive deficits, FTD, negative symptoms, and/or distraction by hallucinations), the interchange necessary for therapy to proceed does not occur. Likewise, if paranoia (especially involving the therapist) is severe, there can be reluctance to attend sessions or engage in the process in a sincere manner. Furthermore, lack of insight into illness can deter engagement in therapy by not seeing a purpose. Despite attempts to reduce these barriers (using medication, cognitive remediation, initial trials of CBTp, etc.), some persons are still not candidates for CBTp. It is difficult to know, however, if the hurdles are too high to surmount. The persistence and patience of the client, therapist, and family often determine how much effort needs to be exerted (and for how long) before reaching this conclusion. Importantly, “progress” is not only improvement, but also the prevention of relapse (including reduced hospitalization). In a given person, it cannot be known if inpatient treatment would have been more likely had CBTp not been used. There are also limitations for those who are able to benefit from CBTp, in that treatment might not completely eliminate symptoms or change quality of life dramatically. Although some persons relinquish their delusions or rid themselves of hallucinations, many retain the symptoms, but in a diminished and more manageable level. The transition from viewing situations as facts to viewing them as one’s own beliefs and finally as internal feelings or “a sense that . . .” shows progress. The feelings can persist without becoming troublesome or leading to bizarre acts or avoidance maneuvers. Complete elimination of the symptoms is often not the end result, but quality of life improves. Likewise, as mentioned above, hospitalization can be reduced with CBTp. Similarly, nega-
Psychosis 251
tive symptoms can be reduced as a person becomes more involved in activities such as household chores or hobbies, even if they are still unable to hold a paid job. Improvement in insight into illness can also be limited. Insight into illness is treated as a type of belief. CBTp methods are used to examine evidence of those beliefs. As stated above, to avoid depression and possible suicide, care must be taken to assess the consequences of relinquishing these beliefs in a given individual. In many, lack of insight persists despite efforts to address and modify those beliefs. Lack of insight does not preclude continuation and usefulness of CBTp for the other symptoms. A person can work on and diminish, if not eliminate, paranoid delusions or voices even as they continue to be unaware of or disbelieving of the symptoms as internal symptoms of a mental health condition. Insight of illness is not necessarily required for one to benefit from CBTp treatment, as problematic symptoms can still be mitigated and quality of life increased. As stated above, another limitation in the effectiveness of CBTp is that medication is nearly always necessary as ongoing treatment for certain conditions with psychosis. CBTp can be used to treat the full psychosis spectrum—from prevention/early intervention with high-risk, prodromal, and first episode populations, to those experiencing mild, moderate, or severe psychosis in the clinical population, either exclusively or as part of other disorders. With some of these populations (e.g., early intervention, prodromal), it would be unethical to administer medication when psychotic symptoms are not present. In use with clinical populations (e.g., schizophrenia, schizoaffective disorder, bipolar disorder with psychosis), it is important to offer medications and explain the benefits and risks of using them, as well as the risk of not taking them, because not taking medication can severely limit the ability of CBTp to have its full effect. General CBT is a short-term therapy that often requires 12 to 16 weeks; however, with schizophrenia and schizoaffective disorder, therapy is typically longer and tends to be most useful as an ongoing treatment. In many cases, frequency of sessions can be reduced in time, but termination of therapy is likely to lead to recurrence or persistence of some symptoms. From another perspective, there are often residual symptoms (commonly negative symptoms) that can still be addressed by continuation of therapy. Although a person might improve by being able to do volunteer work, they may require further therapy if paid employment is desired as the next step. In one author’s (NS) clinical experience, delusions that persisted at first resolved years later as therapy continued. In contrast to schizophrenia and schizoaffective disorder, psychosis as part of mood disorders resolves as the current mood episode ends. Mood episodes may resolve with the use of CBT for depression or mania, so duration of treatment with CBT would follow the norms of those conditions. Other conditions, such as delusional disorder, have variable lengths of therapy. Booster sessions can help in cases when regularly scheduled sessions (even as infrequent as trimonthly) are no longer necessary but symptoms arise after some time, and relearning of certain useful skills can be quick but effective in returning to health.
252 Stolar and Wolfe
PSYCHOSIS AND THE COGNITIVE MODEL In the general cognitive model (Beck, 1976), an event activates an automatic thought (AT) or belief (AB), often influenced by a core belief about oneself, others (the world), and the future. This belief leads to an emotional reaction (including a physiological response) that can have behavioral consequences as well. The individual symptoms of psychosis and schizophrenia can be viewed in terms of this general model. Which components of the model fit each positive and negative symptom can be debated, but one characterization is as such: Hallucinations Hallucinations can be viewed as events and/or as beliefs (when voices are involved). Hallucinations are events partly since the person views the internal stimulus as an external event. The person’s interpretation of the event (ATs/ ABs) are examined in an effort to reduce the severity of the emotional and behavioral responses. Much of the work in CBTp for voices (the most common type of hallucination in schizophrenia) focuses on beliefs about voices (e.g., “who” they are, their power) and the emotions and behaviors (including avoidance) that result. When viewed as beliefs, the content of voices is determined (as best possible) as to whether it reflects the actual beliefs of the person. A voice saying, “The medication is poison,” might reflect a belief that can then be addressed as such using the cognitive model. Delusions Delusions (i.e., firm, fixed beliefs) fit neatly into the model as ATs/ABs. They can be in reaction to specific situations (e.g., “That person on the bus is coughing because they are angry at me”) or be ongoing beliefs (e.g., “The CIA is following me,” or “I have been selected for a divine mission”). Much of the work in CBTp for delusions focuses on examining these beliefs in terms of gathering evidence for and against them and considering alternative explanations. Cognitive components of delusions include a data-gathering bias of jumping to conclusions (Garety & Freeman, 1999), wherein persons with delusions reach decisions utilizing less information (Garety et al., 1991). Further, these persons frequently have an externalizing attributional bias (Garety & Freeman, 1999), which effects are attributed to external causes. Hence, there may be hypervigilance and safety behaviors with paranoid delusions in particular, which serve to alert persons to potential “dangers” while preventing exposure to safe situations (that could potentially dispel the belief of lurking danger). Bizarre Behaviors Bizarre behaviors are behavioral responses that are approached by determining what led to the behaviors—beliefs (e.g., wearing an aluminum foil hat due to a
Psychosis 253
belief that it prevents the government from reading one’s mind), voices (e.g., yelling in public due to hearing and opposing what the voices are saying), or disorganization (e.g., wearing two pairs of pants, a shirt inside out, and a pair of glasses on an angle due to difficulty in organized dressing). Some bizarre behaviors can be more neurological (e.g., catatonic behavior) and therefore not subject to cognitive analysis. CBTp for bizarre behavior focuses on working on the ATs/ABs or voices (as described above) or disorganization (as described below) that might be responsible for the bizarre behavior. Formal Thought Disorder FTD, or disorganized speech, can be considered a physiological response, similar to stuttering. It results from beliefs about situations, leading to anxiety and hence a stress response. Disorganized behavior can be viewed in a similar manner. (This can be distinguished from more purposeful bizarre behavior as described above.) Work with FTD focuses on discerning what events are associated with its onset or worsening, and what ATs/ABs elicited by these events lead to the anxiety. The other symptoms of schizophrenia can be viewed in a similar way, in that stress has the ability to make symptoms such as hallucinations and delusions worse or more frequent (Kingdon & Turkington, 1994). Viewed in this way, work can be done to address situations (and their resultant ATs/ABs and emotions) associated with the symptoms when stress seems to affect their onset and/or severity. Negative Symptoms Negative symptoms can be viewed as behavior or the lack thereof. These diminished behaviors include emotional expression, socialization, motivated behavior, and speech. This halting of behavior may be the result of beliefs that it is useless to even try (e.g., to make friends, to get a job) after years of demoralizing failures (Grant & Beck, 2009). Work in CBTp for negative symptoms aims at dispelling these dysfunctional beliefs (e.g., negative expectancies, negative self-appraisals, defeatist beliefs) mainly by conducting behavioral experiments to show that steps toward desired goals can be achieved. Thus, each symptom can be characterized in terms of the cognitive model. This provides a framework for the symptoms and allows for therapeutic approaches based on this model.
STAGES OF TREATMENT Treatment is divided into stages, including establishing rapport, assessment, goal setting, coping skills, normalization, cognitive/behavioral approaches, case conceptualization, relapse management, and termination (Fowler et al., 1995; Kingdon & Turkington, 1994). Each session consists of symptom ratings, setting
254 Stolar and Wolfe
an agenda, using active problem-solving methods, assigning homework, and eliciting an evaluation. Establishing Rapport CBTp begins with the potentially long process of establishing rapport. It involves the pillars of therapy—listening, empathizing, reflecting, providing a positive regard without judgment, and demonstrating intention to assist the person in progressing. Establishing rapport begins at first contact—in person, by telephone, electronically, or by way of a third party (e.g., parent, spouse, adult child, mental health professional). It takes many sessions to develop. Maintenance continues as long as the person is in treatment. Rapport is especially difficult to establish and maintain with persons with psychosis in that they can develop paranoid delusions about the therapist, making trust a distant endeavor. In these cases, rapport must be reestablished repeatedly. In addition, poor insight into the need for help limits the desire of clients to engage in therapy, hampering the building of rapport by keeping objectives disparate. Assessment As with establishing rapport, assessment is a stage that can start before meeting a client—when one learns why the person is seeking or being sent for treatment—and continues throughout treatment until one assesses readiness for termination and referral. Depending on the cooperation of the person treated, full assessment may need to be delayed until enough rapport is established. Although many treatment facilities require a complete evaluation in the initial session (as guided by specific clinical procedure codes), it may be more clinically practical to spread the initial assessment questions over a number of sessions. Formal assessment uses standard psychiatric/psychological evaluations. Specific items include determining for each symptom the severity, frequency, duration, pervasiveness (i.e., how much it affects the person’s life), preoccupation (i.e., how much attention is paid to it), distress induced, personal explanation, precipitants, aggravating/ameliorating factors, nature of onset (i.e., age, circumstances, reaction), and development. Additional information is obtained for auditory hallucinations of voices (e.g., number of voices, familiarity, gender, intervoice communication, and content of what the voices say) and for delusions (e.g., content and conviction—to what extent the person believes each to be true). Often, information from the person in therapy about current symptoms is limited due to poor insight or distrust of the assessor (including fears of being hospitalized or further medicated). Reports might come from family, friends, hospital records, or others. Care is needed in how this information is presented to the person in therapy, but it can be an opening to further elaboration of the descriptions of the symptoms.
Psychosis 255
Assessment is also an integral part of each session. CBT focuses on specific situations as a way to learn from them and generalize to similar situations and on the cognitive, affective, and behavioral reactions to them. The initial step in working with a specific situation is to assess it by gathering information about it—the thoughts/beliefs it elicited, the emotions resulting from the cognitions, and the behaviors and physiological reactions produced by the emotions. The person’s reaction to and interpretation of the symptoms, as well as how they may have been exacerbated or diminished by reactions of the person (such as isolating), are also important. The assessment of individual situations begins with whatever the person presents first as prominent. It could be the event, emotions, behaviors, physiological reactions, or the thoughts/beliefs themselves. However, it can help to conduct the assessment with the symptom as the starting point. Depending on the person’s perspective, the symptoms can be considered as various parts of the cognitive model. If viewing hallucinations as events, they need to be assessed in terms of the beliefs about them, leading to physiological responses and possibly behavior. Alternatively, if hallucinations are presented in terms of their content, assessment of the preceding step (situation) and resulting steps (emotions, physiological reaction, and behavior) fill out the story. Goal Setting Goal setting can be particularly difficult with people with psychosis because often there is little insight regarding having anything problematic on which to work. People with this condition are often persuaded by family or ordered by the legal system to engage in treatment. Eliciting goals on which to work from the people with the condition may be considered fruitless to some. However, CBTp is most effective when working towards an individual’s self-identified goals (Chadwick, 2006), regardless of how unrealistic they might seem (Riggs, 2019). Discussing the reasons as to why the individual would want to reach their identified goal, and what accomplishing that goal would mean to them, can aide in understanding the purpose that their identified goal would serve. With that information, one can break the goal down into smaller, achievable steps to focus on throughout treatment (Riggs, 2019). Family members serve as an additional source for information on an individual’s goals, but relying completely on goals generated from others deviates from the tenet of CBT to focus therapy on the goals of the person coming to therapy. A good starting point is asking the person what changes they would like to have happen in their life. When this is frequently followed by replies similar to “Nothing,” a more focused second approach is how they would like things such as voices, disturbing beliefs, difficulties in communication, socialization, employment, and so on to change. Sometimes, goals are indirectly related to symptoms. For example, getting a job could be a stated goal with voices being a barrier which can then be worked on directly. Another approach is when the
256 Stolar and Wolfe
person in therapy says they do not know why they are there, the goal for therapy can be addressing the issue of others wanting them to go to therapy when they do not know why (D. Foster, personal communication, 2004).
Coping Skills Therapy first addresses aspects of the condition that can interfere with the interpersonal, interactive, communicative requirements of the core therapy process. Some of these barriers are overcome as rapport is established, but others involve levels of symptoms too severe to allow formal therapy to proceed. The latter can be addressed using coping skills, often behavioral in form (Fowler et al., 1995), that can also be used at any stage of therapy when needed. Once symptoms are reduced enough, cognitive techniques can be applied. Coping skills, as with any treatment, need to be individualized. What works for one person might not work for another—or might even be deleterious. Therefore, it is best to begin with having clients list and rank order by effectiveness any coping skills they are already using or have used in the past, including ones that did not work or made things worse (Riggs, 2017). Second is identifying factors that exacerbate or ameliorate symptoms, and respectively reducing or promoting these precipitants. For instance, if voices worsen in social settings, the behavioral strategy of temporary solitude can be used to reverse this. Again, individualization of treatment is important, as some have voices that worsen in isolation, so for these, promoting social settings is the direction to proceed instead. In many cases, specific social supports can help in alleviating symptoms. Any factor that increases or reduces stress is a candidate for use as a coping skill (by eliminating or introducing that factor, respectively). Delusions and/ or voices can worsen in the presence of strangers or of familiar others. If symptoms become severe, moving away from such people helps keep those symptoms in check. These types of coping skills are often temporary fixes, as maintaining them can be unfeasible and/or countertherapeutic. A person becoming visibly agitated due to voices exacerbated by the presence of Uncle Charles at Thanksgiving might need to retreat to a bedroom for much of the evening, but this strategy is best supplanted by others that do not disrupt family events. Third is utilizing physiological strategies, which include relaxation methods such as deep breathing, progressive muscle relaxation, or meditation. Other coping skills specific for auditory hallucinations include attentional strategies in which alternative auditory processing tasks interfere with the hallucinations. These include listening to music (Breier & Strauss, 1983), reading (silently or aloud), humming, or repeating what voices are saying. Attentional strategies using distraction are another way to provide competition with the symptoms of hallucinations and delusions. For example, look, point, name is a way to ground a client in attending to external stimuli as a way to reduce the attention to internal stimuli. The individual is instructed to look around, point to objects one at a time, and name each in turn.
Psychosis 257
Normalization Once coping skills have reduced the severity of symptoms, the verbal interactions of therapy sessions can proceed. An important component of CBTp, which applies to all symptoms, is normalization (Kingdon & Turkington, 1994). It can be used at any time in the course of therapy, and its repetition can be instructive. Normalization can be viewed as a type of acceptance (as prominent in Acceptance and Commitment Therapy [Hayes et al., 1999] and Dialectic Behavioral Therapy [Linehan, 1993]) in which a person learns to accept their condition while paradoxically making efforts to improve. Normalization goes beyond acceptance, showing how symptoms of psychosis can occur in any of us. Evidence is presented to diffuse the belief that one is odd or strange for having these symptoms. In this approach, the primary target for therapy is the distress, not the content of the beliefs. For one, certain conditions—ingestion of certain drugs, extreme lack of sleep, extreme stress, sensory deprivation—can induce true psychosis in anybody. Other, more common, situations can produce reactions similar to psychotic symptoms. Loss of a loved one can lead to hearing that person’s voice. Hearing one’s name called when no one appears to be doing so can happen to many without a mental health condition. Many of us have beliefs that can be considered as somewhat paranoid, referential, or grandiose. How many of us, hearing a police siren some distance behind us on the highway, suddenly check our speedometer and try to recall if our car is in good order, thinking the police siren is likely meant for us? When a car turns around in our driveway, we wonder what they are up to. Once the situation passes (the police go past us after someone else; the car that turned around goes off without event), we are relieved. Someone with psychosis might think there is still something afoot— the police made note of their license plate; the car now knows where they live. The initial assumption of something being wrong (paranoia), was made, nevertheless, by both groups. As for grandiosity, many people buying lottery tickets or supporters of a sports team watching a game have a strong belief that this time they are going to win. We make many assumptions and generalizations that protect us by assuming potential threats to, and possible greatness for, ourselves. Much of general CBT addresses these kinds of assumptions. To illustrate further, a person watches a horror movie. That night in bed, they notice out of the corner of their eye something that scares them, or they feel there is a presence in the room. Although this belief is similar to a paranoid delusion, the conviction is much less. The person who watched the horror movie, upon having this belief may say, “I am scared because I watched a horror movie. This is my mind playing a trick on me,” whereas a person with a paranoid delusion will have a stronger feeling that the belief is real and not attribute it to their imagination. The content of delusions can be normalized. Although many delusions seem bizarre, the content is often like that found in science fiction novels, dreams, and song lyrics. Although people without psychosis can create these same
258 Stolar and Wolfe
ideas, the strength of the beliefs differ. Furthermore, beliefs that are considered delusional in psychiatric populations cannot be distinguished, based on content alone, from new religious movements (Peters et al., 1999). Psychosis can be regarded as one end of a spectrum, not as a distinct, unusual anomalous condition. For instance, approximately 10% to 25% of the general population has heard voices at least once in their life (Slade & Bentall, 1988), and 60% to 80% percent of the population has heard a voice (Romme & Escher, 2000). There are many people who hear voices but lead otherwise normal lives. Many of these voice-hearers, as they call themselves, learn to merge the voices into their daily lives and do not require treatment (Romme & Escher, 1989). Paranoid beliefs are widespread and exist on a continuum, occurring throughout the general population. They are believed to be associated with the same mechanisms occurring in anxiety disorder (e.g., interpretation bias, hypervigilance, safety behaviors; Freeman et al., 2005, 2008). Moreover, such safety behaviors influence maintenance of the underlying threat belief (Freeman et al., 2016). The process of normalization can help reduce the stigma of “mental illness” and view it as a condition that one can learn to manage in order to live to one’s own potential. This in itself can reduce distress associated with the symptoms of psychosis. Cognitive/Behavioral Approaches The core of CBTp is a verbal, collaborative interchange between client and therapist in which beliefs of the former are evaluated by examination of evidence supporting or opposing these beliefs, while considering alternative explanations. This process is guided discovery, in which the therapist, through the use of Socratic questioning (i.e., probing questioning meant to stimulate critical thinking and to elicit ideas), gently leads the client to challenge their beliefs. Behavioral experiments, such as trying out a behavior to see if feared outcomes actually occur, enhance the cognitive approach by modifying beliefs on the basis of in vivo data. The techniques involved in these essential aspects of CBTp are presented in more detail in sections relating to the various symptoms of psychosis, as well as to the negative symptoms. Case Conceptualization Although specific therapeutic techniques are very useful in the treatment of psychosis, an overlying assessment and characterization of a person’s condition and reaction tendencies allows for a broader view and thought-out strategies over the mere use of one technique after another. The development of a case conceptualization (Morrison et al., 2004) and its presentation to the client provides a means to illustrate this overview, develop a hypothesis of how symptoms and problems formed and are maintained, and suggest treatment options.
Psychosis 259
Although CBT focuses primarily on the here-and-now, case conceptualization begins with precedents for the current situation. The first are genetic and prenatal/perinatal factors (Beck et al., 2009), pertinent for schizophrenia and many other conditions with psychosis. For a given individual, the degree to which these factors are relevant in the etiology of the condition is not typically known; however, it can be informative to clients to see that these factors are part of how their conditions came to be. Sometimes this leads to relief that the condition is not their fault. Other clients could take this to mean that they are serving a life sentence with this condition. Care needs to be taken when providing this general information. Developmental influences, such as traumas or events at home, school, work, or with friends, can contribute to how vulnerable to symptoms someone is (Kingdon & Turkington, 1994). Genetic and developmental aspects are predisposing factors. The degree to which each category contributes (nature vs. nurture) is an ongoing focus of exploration. More proximal factors leading to the onset of symptoms are determined by gathering a detailed history—when they first occurred; what was happening at the time (especially stressors present); and thoughts, beliefs, emotions, behaviors at the time. Sometimes the content of voices and paranoid delusions reflect actual incidents in the person’s earlier life, implying that the incidents may have contributed to the onset. These incidents can be examined using CBTp techniques because they could still be influencing the person’s current emotions, thoughts, and behaviors. The next step in developing a case conceptualization involves compiling three to four samples of thought/belief records that represent common themes for the person. The records include events, ATs/ABs, and meanings of the beliefs, emotions, and behaviors. These are used to determine key symptoms, problems, core beliefs (i.e., unconditional assumptions about self, others, and the future), and conditional assumptions/beliefs/rules of how to cope with the core beliefs (e.g., “If I am being followed by the CIA, I am an important person,” as a way to cope with a core belief of “I am an insignificant person”). Next, precipitating, perpetuating and protective factors are listed. These are, respectively, (a) current triggers for symptoms; (b) thoughts and behaviors maintaining the symptoms; and (c) strengths, social supports, and positive patterns of behavior protecting against the symptoms. Coping or compensatory strategies (such as social isolation or vigilance) can be helpful in dealing with symptoms, or at times they can become problems themselves (Leahy et al., 2005). The case conceptualization serves to illustrate the origins of the problems and a working hypothesis of how the various factors and reactions above might be linked sequentially, suggesting a plan of treatment and a prediction of what obstacles to treatment might arise and how to overcome them (Persons & Tompkins, 1997). The case conceptualization guides the therapist and is presented to the client to increase understanding of one’s condition. However, insight gained from a
260 Stolar and Wolfe
formulation can have various effects (including depression and suicidality), so, again, care must be taken in the presentation, and in some cases, it might be best to limit it and introduce it gradually. Treatment Completion The ending of treatment is not always indicated, as many with psychosis require ongoing therapy. Progress in CBTp can be slower than that with nonpsychotic conditions. If symptoms remit, or at least improve, they often do so sequentially. Positive symptoms tend to improve before negative ones. Ego-dystonic (i.e., incongruent with one’s desires) delusions might be rejected before ego-syntonic (i.e., congruent with one’s desires) ones. Auditory hallucinations may continue to be present but less intrusive, whereas other symptoms persist. When indicated, the ending of treatment is a critical part of the process. It enables the person to continue treatment by treating oneself independent of the clinician, and to evaluate when return to formal therapy is needed. Relapse Management Part of the process of therapy is maintaining gains made and addressing relapse prevention, which consists in part of reviewing techniques that helped bring about remission. Frequently, skills learned in therapy to manage, diminish, or resolve symptoms need to be practiced on an ongoing basis. Another aspect of relapse prevention is identifying and acting upon early signs of relapse. The constellation of early signs varies among persons and conditions. For bipolar disorder (and schizoaffective disorder, bipolar type), less need for sleep and increased goal-directed activity can be the first signs of relapse. With schizophrenia, social isolation and talking to oneself could be early signs for some and have little clinical significance for others. Early signs signal clients, family members, and agency staff that a person might need to return to therapy or increase the frequency of therapy sessions. Medications might need to be adjusted and CBTp skills reminded, prompted, relearned, and/or resumed. As with initial therapy, coping strategies (such as listening to music when voices get worse) may be all that is needed.
ESSENTIAL COGNITIVE BEHAVIORAL THERAPY FOR PSYCHOSIS Formal CBTp proceeds virtually in the same manner as that for other conditions (Beck et al., 2009), with some minor adjustments (described below in the negative symptoms section). The basic focus is on identifying ATs/ABs and examining them for supporting or refuting evidence. Especially if there is only weak support for the beliefs, alternative explanations for the observed event(s) are determined and possibly tested. There is an emphasis on the person’s subjective experience and personal meanings given to events. These meanings are elicited and examined, but they may only be revealed after many sessions.
Psychosis 261
The types of beliefs examined differ for the various symptoms. For hallucinations, it is beliefs about the hallucinations, including the source of the hallucinations (e.g., demons, deities, aliens), their power, and so on. It might also involve the content of voices, for example, when they say derogatory comments. For delusions, the beliefs are the content of the delusions themselves. These include grandiose, paranoid/persecutory, somatic, religious, and so on. For FTD, the beliefs could relate to what the person believes others might think of them or to whether they are capable of social interaction. Other beliefs are possible contributors to the stress leading to FTD. For negative symptoms, the beliefs tend to center around an inability to accomplish anything successfully or to be valuable or worthwhile (Beck et al., 2009). Cognitive Behavioral Therapy for Delusions Often, beliefs that are delusional are firmly held but isolated from their context. There are several CBTp approaches to delusions, including general normalization of delusions, first-generation reasoning experiments, and more recent interventionist causal approaches. The first-generation CBTp approach focuses on whittling down the beliefs by examining the context (context elaboration) in terms of logical conditions and logical outcomes. If the event had actually happened, what must likely have preceded and followed it, and is there evidence for these contextual items? To illustrate, a person believes that a man from her day program is in her bedroom in a house she shares with her aunt. One can ask how he got into the house. By the time she reports the event to a therapist, she should be able to say her aunt let him in, he got in via an open door/window, or it was a break-in. These are logical conditions to the man being in her bedroom; however, delusions are often single concepts (“The man is in my bedroom”) without the logical context. Next, the therapist could ask if she yelled for her aunt, called the police, or asked the man why he was there and told him to leave. These are logical outcomes. Also, because she sees him at least weekly, one can ask what she said when she next saw him. One author (NS) has a client with a similar scenario who did not have answers to any of these questions. This delusion was brought up by the client many times, with the therapist asking these questions each time it “occurred.” Eventually, the client changed her presentation of the story from the man being in the room to her feeling as if he was in the room. Without a context of logical conditions and outcomes, the delusion weakened from a belief to a felt sense. Sometimes, rather than the absence of a logical condition or outcome, there is an absence of logical arrangement of the immediate context of the delusional material. For example, a person stated a staff member who shared her living space was touching her inappropriately. When asked where she and the staff member were when this happened, she said that the staff member was at her bedroom door while she was lying in bed (some distance from the door). She had difficulty explaining how the staff member touched her from that distance. This exploratory questioning provides insights into delusions that can prove
262 Stolar and Wolfe
useful in other ways to understand particular delusions. In another example, one person had delusions of knowing famous people. Once, the therapist asked where the famous person was physically located at the time. The person responded that they were in her room on the television. This helped in determining how her delusions started with seeing celebrities on television and then grew into believing she knew them personally. Examining the evidence for beliefs is conducted in various ways using (a) guided discovery (with the therapist adapting a pseudoinnocent wondering, called the Columbo method, after the 1970s TV detective), (b) Socratic questioning (i.e., probing questioning to stimulate critical thinking), (c) behavioral experiments (i.e., testing beliefs using action, such as testing “Others will ignore me at parties” by going to a party and seeing how many people say “Hello”), (d) evidence for and against charts, (e) externalization of voices (i.e., use of a different term is more appropriate with this population), (f) pie charts, and (g) spectrum lines (Beck, 1976; Burns, 1980; Greenberger & Padesky, 1995; Morrison & Barratt, 2010). Other creative methods are used to help people test the validity of their beliefs. For example, one person believed people from cars pulling up to his apartment building would invade his apartment. This client was asked to tally the times during the month he heard a car park outside his building and (a) people from the car invaded his apartment or (b) nobody invaded it. He brought back the paper with many checks indicating no invasion of his apartment and none indicating an invasion. When asked what he thought of his experiment, he said that he guessed people from the cars parking outside were not necessarily going to invade his apartment. Another person thought others could read his mind. His therapist asked if he would be okay if the receptionist (whom the client knew well) could join them to test his belief, and if he would believe the receptionist’s response. He agreed to both. Note that it is important in these experiments to establish, in advance, the client’s acceptance of the results. The receptionist was asked what the client was thinking. She said she did not know and was excused. When asked by the therapist, the client said he guessed people could not read his mind. Although these examples may seem like simplistic ways to disprove delusional beliefs, sometimes delusions rest on weak foundations that can be easily shattered by testing the beliefs directly, as these examples show. As another example, a person used a recording to test her belief that she said inappropriate things in front of her family. With the built-in recorder on her cellphone, she monitored what she said when she thought this event was occurring. Listening to the recordings revealed the absence of the believed event—she did not hear herself saying anything inappropriate to her family. Particularly when it is hard to prove a belief to be false or true, looking for alternative explanations is another way to loosen the tenacious grip of delusional beliefs. Even if the initial belief remains the primary belief, the presence of plausible alternative explanations can weaken its strength. For example, a person believed a blimp after a sports event was following him as he walked to
Psychosis 263
his car. He rated this belief as 100% certain. When asked for other explanations for the blimp’s apparent movements, he denied any. He was then asked to give alternative explanations even if he did not believe them. He came up with the following: (a) the blimp happened to have turned the direction he had; (b) the blimp only appeared to have changed directions; and (c) the blimp changed directions first, but he thought he had turned first. After offering these explanations, when asked again about the strength of his belief that the blimp was following his movements, he lowered it to 95%. Although this may seem small, it was “a foot in the door.” What had originally been a fixed, firm belief became open to questioning once alternative beliefs were considered. In another example, where it might be difficult to determine if a belief is true or not, a person had the delusion that strangers he would see in such places as convenience stores were angry at him. This would lead many times to the person hitting the strangers. The therapist showed the client a paper (found in many therapy offices) containing cartoon drawings of labeled emotional facial expressions. The therapist covered the emotion labels and asked the client to identify each emotion. The client considered the smiling face as “happy” but all the others (including neutral, surprised, sad) as “angry.” It was difficult for the client to question his delusion by examining the evidence. Although the client did not have much evidence that strangers were angry with him (except for questionably angry faces), the absence of evidence did not convince him of the likely falseness of his delusion. For more direct evidence, he would have had to approach strangers and ask if they were angry with him. It was more fruitful for the therapist to address the client’s delusion with two sets of alternative explanations relating to the strangers’ emotions and their connection to the client—namely to consider the possibilities that the strangers were experiencing emotions other than anger, and if they were angry, they might be angry at something unrelated to the client. With these considerations in mind, the client was able to question and then ultimately reject his habitual delusional belief. This, in turn, resolved his aggressive behavior toward others. A form of examining the evidence is considering the belief to be due to the mental health condition itself. This approach is a delicate one. Increased insight into one’s condition can have various effects. For some persons, it will be a relief that they are not to blame for their situation (e.g., of not having a career, family, or housing of one’s own). Others may see it as devastating to think that one’s beliefs, possibly decades-long, have been due to some deficit in one’s thinking ability—and that one is forever limited by this condition. Depression and suicidality are potential consequences of this type of epiphany. It is important to individualize this topic. Each person’s reaction to this realization must be assessed before embarking on this discussion. One way to do this is to present the possibility of a delusion being false as a hypothetical, asking the person how they might feel if this was the case. Much progress can be made even without insight into one’s illness, but it can be helpful to approach the topic if a person appears ready.
264 Stolar and Wolfe
One way to venture gently toward the idea is to make the connection between stress preceding symptoms and the occurrence of the symptoms themselves. As a person comes to notice that voices and beliefs worsen during stressful situations, they might realize that these symptoms are dependent on their state of mind. It is usually a small step from this to statements such as, “It must be my mind playing tricks on me,” or “It’s all in my head.” In rare cases, attaching medical labels such as schizophrenia and delusional disorder may be useful, but more often, they are not necessary once the person considers the alternative explanation that some of their beliefs (and the presence of voices) are produced internally as opposed to being actual, external phenomena. At times there is a diminishing belief progression seen in the development of a person’s view of their delusions. Initially, delusions are considered to be facts. As the delusions are questioned over time, and as they discover that others do not share the same view of the “facts,” the delusions start to be viewed as personal beliefs. With more time, some persons who have challenged their own beliefs with repeated use of examining the evidence and considering alternative explanations begin to rephrase their beliefs as feelings (see Garrett, 2019; Nelson, 1997). The person who said a staff member of an agency she attended was in her house behind her when she was in bed came to rephrase it as “It feels as if he is right here behind me when I am at home in my bed.” This was arrived at after many instances of her reporting the recurring event as a fact and of being asked about logical conditions and outcomes (to which she was unable to provide answers). It is not necessary (and potentially detrimental) to challenge a person’s felt sense. It is best to validate the presence of the feelings and then educate the person that feeling (or “sensing”) something is occurring does not mean that it is. Examining the evidence and considering alternative explanations (the cornerstones of good science) are the steps that follow these feelings. Another way that progress in therapy might be partial, yet beneficial, is when clients no longer talk about delusions or allow them to influence their behavior or emotions, thus appearing to have relinquished them. Only when questioned about them is it known that they have not been completely abandoned, yet it might only be when probed that they think about them. Challenging beliefs is a delicate process better termed “guided discovery” and “Socratic questioning.” People with psychosis have endured years of others challenging their beliefs, yet they continue to cling to them. Facilitating the processes of examining the evidence and considering alternative explanations rather than directly confronting delusions more often leads to gradual rejection, alteration, or dampening of the importance of these beliefs. Therapists can facilitate these processes by first encouraging clients to provide examples of evidence for or against the beliefs and to consider alternative explanations for the events that led to assuming the delusional beliefs. If someone has difficulty producing their own examples, the therapist may suggest other possibilities. However, this should be done sparingly and in a collaborative, exploratory manner. Direct confrontation of delusions can lead to a more entrenched belief as well as confabulation (i.e., elaboration of the delusion to address logical
Psychosis 265
challenges of it). An example of confabulation is adding to the delusion of an implanted listening device to say that it is microscopic, after being told it should appear on an x-ray. Confabulations can be incorporated into the delusion such that next time it is presented as if it was always part of the belief. At times, delusions serve a helpful purpose for the person. Most grandiose delusions have desirable qualities, but nongrandiose delusions, such as being married with children and having a regular job, can also be satisfying. Even paranoid delusions can have positive meanings if one’s importance feels enhanced by having important others (e.g., CIA, devil) follow and threaten them. Examining the evidence, considering alternative explanations, and other logical arguments have limited effect when desirable personal meanings are emotional anchors keeping the delusion in place despite utilization of cognitive techniques. The first step to dislodge emotional anchors is to identify the meaning behind the delusion(s), or what purpose it serves. A way to determine this is to ask the person what it would mean if the belief were true, or if it were not true. For example, if a person believes that they are a celebrity, the practitioner asks, “What’s good about being that person?” The person replies that it means they are talented, important, and liked by others, thus reflecting the possible purposes the belief is serving (to feel talented, important, and well-liked). Once the meaning is identified (which may not always be completely determined), the person can brainstorm (facilitated by the therapist) other means by which these meanings can be accomplished. In another case, an unemployed, unmarried college graduate with the delusion of being employed by the CIA was encouraged by her mother to read novels as opposed to passively watching television (and not being able to report what shows she had been watching). Therapy consisted in part of “quizzing” the person about the content of novels she was reading to ensure that she was doing so and to help her exercise her cognitive functioning through recall and summarization. Her delusion about being employed by CIA eventually subsided, potentially in response to the enrichment of her life with her return to reading. The concept of emotional anchors holding delusions in place is a specific example of a more recent approach to change in delusions that incorporates an interventionist-causal model (Kendler & Campbell, 2009). This model addresses delusions by specifically focusing on and targeting hypothetical factors that are involved in the formation and maintenance of delusions (Freeman, 2007; Freeman & Garety, 2014; Garety et al., 2007) without challenging the delusion itself (Mehl et al., 2015). Studies using the interventionist-causal model approach have focused on cognitive or emotional factors involved in the formation and maintenance of persecutory delusions such as reasoning biases (Waller et al., 2015), negative self-evaluations (Freeman et al., 2014), and worrying (Foster et al., 2010; Freeman et al., 2015). In their worry-intervention study, Freeman et al. (2015) used CBT to target and reduce worry in persons experiencing persecutory delusions and found, via mediation analysis, the change in worry may have accounted for 66% of the change in delusion, with reductions maintaining at a 24-week follow-up (Freeman et al., 2015). A meta-analysis on the effect
266 Stolar and Wolfe
of CBTp on delusions (Mehl et al., 2015) found first generation CBTp techniques to be superior to treatment as usual (TAU) with regard to delusion modification, which is maintained through the course of a follow-up period. However, they did not find the first generation CBTp methods superior to other effective interventions, such as those using the interventionist-causal model approach to delusion modification, at end of therapy nor at follow-up. It is important to recognize that delusions can also often be misinterpretations of real situations. Asking for evidence can expose real events leading to the production of the delusion. One elderly woman living in a residential facility reported that people in the building next to hers would come into her room at night and deliver, then steal, her newborn child. When finally asked what led her to this belief, she stated that she would wake with her bed wet. It turned out that, unbeknownst to the staff, she had urinary incontinence and changed the linen herself. This delusion informed the staff of this frequent occurrence. Later, she developed a heart condition, which was being treated when she started having a delusion that she was being stabbed in the back. When asked for evidence, she reported that she could feel the point of the knife “right here,” as she pointed to the left side of her chest. Had the heart condition not been previously identified, this delusion could have been the first indication that she was experiencing chest pain. Cognitive Behavioral Therapy for Hallucinations Cognitive behavioral treatment for hallucinations focuses partly on the beliefs about the origin and power of the hallucinations (Chadwick et al., 1996; Fowler et al., 1995), which tend to be auditory and mainly voices. Persons often believe voices to be from deities, aliens, demons, or other powerful sources. They often believe threatening voices are powerful enough to fulfill their threats. This leads to fear that if commands are not followed, the threat will be carried out. As with other delusions, examining the evidence and considering alternative explanations are the mainstay of treatment. Specifically, persons are queried about evidence for the belief that their voices have external sources. It is hard for persons to prove this—at best, the voices seem to be coming from outside oneself. Supporting evidence would include others hearing the voices, but these persons usually have experience of others saying they do not hear them. This has not swayed their belief in the voices. A method of testing the existence of voices is through the use of audio recording equipment; voices caught on the recording provide proof of existence, and their absence provides evidence that they do not exist. An illustration of utilization of tape recorders (or built-in recorders on cellphones or other electronic devices) is a person asked to record when she believes she hears neighbors or her mother (away at work) talking to her. The recording is played back to reveal the absence of the believed event— she did not hear neighbors or her mother talking to her. Prior to this experiment, the person would call her mother at work (or waking her, late at night), asking if she was home and talking to her. This method to gather evidence
Psychosis 267
became disruptive for the mother, so the recording technique helped alleviate the disruption. With regard to the voices being powerful enough to fulfill threats, evidence against this includes that the person often has not obeyed the commands (ones such as hurting oneself or others) for many years and yet the alleged source of the voices has not fulfilled the threats. Although this conclusion may seem obvious, persons in this situation often overlook it. Consideration of alternative explanations includes that the voices are produced internally. As previously stated, as persons notice the connection of the presence or worsening of the voices in the context of stress, the conclusion that these voices must be produced by themselves arises. This eliminates the belief that the voices have any power or threat. Persons also discover they can at will initiate, terminate, and raise or lower the volume of auditory hallucinations (Fowler & Morley, 1989). This is best initiated with practitioners who coach the person on how to do these maneuvers. This technique helps persons realize the voices are produced internally since they can be internally manipulated. As with other symptoms, the belief that the phenomenon is produced internally can lead to recognizing it as something that can be treated. A second method to address voices is to consider the content of what the voices are saying. Sometimes voices reflect a person’s beliefs. For instance, a client in an initial psychiatric evaluation said her voices told her that the new agency was trying to poison her with medication. When asked if she believed what the voices said, she replied she did. This opened up discussion of the risks and benefits of the medication, that it was her right to refuse to take the medication at any time, and the strategy of starting at a low dose to see how she handled the medication. This consequently led to her agreeing to take the medication, which she continued to do long term. Assessing if voices reflect a person’s thoughts/beliefs consists of simply asking whether what the voices are saying is also what the person believes. If so, discussion can then shift to the person’s belief itself, sometimes no longer needing to examine the beliefs about what the voices are. Care must be taken not to assume that the content of voices reflects the person’s own beliefs. They can alternately reflect what others have said to that person (such as derogatory comments). Asking the person if they share the belief of the voice can provide clarification. Cognitive Behavioral Therapy for Other Positive Symptoms Additional positive symptoms include bizarre behavior and FTD. Bizarre behavior results from delusions, hallucinations, or disorganization. If someone wears a hat of aluminum foil because of the belief that aliens are reading their mind, then this behavior is best addressed by working on the delusion using CBTp methods. If a person shouts at unseen entities in public, gently determining if this is in response to auditory or visual hallucinations, followed by working on corresponding phenomena as described above, is the preferred approach. If nothing else, these approaches demonstrate understanding of the person by
268 Stolar and Wolfe
tuning in to the perceptions and beliefs behind the bizarre behavior rather than viewing the behavior from a bewildered stance. Many appreciate this attempt at greater empathy. At times, bizarre behavior is not associated with delusions or hallucinations, but rather is due to disorganization, one of three factor-analyzed subcategories of schizophrenia (the others being delusions/hallucinations and negative symptoms). Bizarre behavior of this type includes repetitive, meaningless movements (perseveration) and erratic behavior. Although using an aluminum hat is considered bizarre, it is a fairly organized behavior. Treatment of disorganized bizarre behavior is similar to that of disorganized thought/speech (FTD—also in the subcategory of disorganization). Although mostly handled with the use of medication, disorganization can be indicative of a stress reaction. Conceptualized in this manner, it can be reduced (although possibly not completely eliminated since other factors may be involved) by determining the ATs/ABs behind the emotions (especially anxiety) leading to the stress reaction that includes bizarre behavior. This can be difficult, as disorganized behavior is often accompanied by disorganized speech. One can use behavioral coping skills first, such as removing suspected stressors (e.g., certain people, places) and seeing if disorganization diminishes. A person could learn relaxation methods and be encouraged to use them when disorganization ensues. Examining and modifying irrational beliefs about the avoided people and places leads to further diminishing of anxiety (and the accompanying disorganization and bizarre behavior) and eventual reduction in the avoidance of these people and places. FTD itself contains verbal content—confusing content, however. Sometimes the content is meaningful, but these meanings take effort and exploration to determine since many have personal, obscure meanings. Additionally, explanations persons give frequently are disorganized themselves. An example of searching for personal meanings of seemingly meaningless speech is a client with bipolar disorder with psychotic features seen by the treatment team on rounds. A respiratory consult had determined the need to initiate treatment with an inhaler. The client, with FTD evident throughout her hospital stay, answered “Model.” The treatment team was confused by this response until one member (NS) asked if she was concerned about the recent, publicized death (from using an inhaler) of the sister of a famous model. The client responded affirmatively, so the team gave a detailed explanation about the inhaler and its benefits and risks. The client agreed to use the inhaler. Although this example presents the method in its simplest form, other attempts to decipher thought-disordered content in a collaborative manner can also lead to understanding what a person is communicating. Through the process, a person may feel understood in ways they have not with most others, as the more typical approach is to politely nod as if what is said is understood when it really is not. This feeling of being understood can reduce a person’s stress and thus turn a vicious cycle of stress to worsening speech to worsening stress into a virtuous cycle of feeling understood to less stress to improved speech to being more understood.
Psychosis 269
Another approach to FTD is to have clients listen to tapes of themselves. This leads to reduction of its severity, which leads to improvement in quality of life. While in session, one client listened to tapes from the previous session and remarked, “That was me rambling,” when examples of FTD occurred on the tape. His thought-disordered speech improved markedly, and he was subsequently able to secure a managerial position at a food delivery establishment. Cognitive Behavioral Therapy for Negative Symptoms Much of CBTp research and treatment initially focused on the positive symptoms of delusions, hallucinations, and FTD. The negative symptoms of amotivation, apathy, affective flattening, asociality, and alogia were less amenable to the basic techniques of CBT. Negative symptoms seemed biologically based, as did neurocognitive deficits of diminished attention, memory, and executive functions. These did not seem to derive from beliefs. However, some studies showed positive changes in the negative symptoms when positive symptoms were mainly addressed (Rector et al., 2003). Later, work focusing more directly on negative symptoms showed significant results (Grant et al., 2012). Beck and associates (Rector, 2004; Rector et al., 2005; Grant & Beck, 2009) conceptualized negative symptoms as based on years of persons not succeeding in typical life functions—career, relationships, forming a family, and so on. These shortcomings led to the demoralized belief that it was not worth trying to do much of anything—certainly not to try anymore to get a job, a relationship, or have children. A vicious cycle of not doing well in the world leading to defeatist beliefs, then to retreat, and eventually to diminished ability to do well in the world characterizes the fate of those with negative symptoms. Reversing this cycle requires changing the belief one will not succeed into one of potential achievement. The first step is to identify a client’s personally meaningful goals. Next, the essence of these goals is elicited, such that accomplishable goals that meet the essence of the original goals can be formulated. For example, if a goal is to become the U.S. president, the essence might be being a leader, and an accomplishable goal might be to become a client coleader in a day program. Small steps are plotted out in that direction. The client is then assisted in achieving the first step. The belief that they cannot do the step (if present) is addressed and tested with a behavioral experiment. An example from Beck’s group (Grant et al., 2014) is an elderly woman who frequently called hospitals asking if they needed her help. Though seemingly benign, the frequency of calls was disruptive to hospitals. The therapist started with identifying the client’s personal goals. She stated she wanted to make coffee for people at her program. She did not know how to make coffee, so the therapist helped her learn during their sessions to make it and deliver it to persons at the therapist’s office. After discovering that she could make and deliver coffee, the client eventually achieved her goal of making it for her program. This accomplishment led to cessation of her calling the hospitals. The experience of making coffee for her program and the thanks she received appeared to
270 Stolar and Wolfe
give meaning to her life so that the pleas to the hospitals to help were no longer necessary (Grant et al., 2014). Along the lines of Viktor Frankl, Carl Rogers, Martin Seligman, and others, addressing meaning in one’s life is an important part of mental well-being. An accompaniment to addressing negative symptoms by examining validity of beliefs of inability to accomplish certain tasks, work on neurocognitive deficits helps not only the process of therapy, but also the ability to accomplish specific goals. Cognitive remediation/rehabilitation therapy (CRT; also confusingly referred to as cognitive therapy) utilizes computer “games” to provide systematic practice of neurocognitive skills (Wykes & Reeder, 2005). Whereas CBT focuses on higher levels of cognition (i.e., thoughts, beliefs, assumptions), CRT works on the building blocks of cognition, including neurocognitive skills such as attention, memory, decision-making, and planning. CRT works similarly to physical rehabilitation, enhancing basic skills through repetitive exercising of those skills in a gradual, progressive manner. CRT is outside the domain of this chapter; nevertheless, it is used to enhance the work of CBTp by improving basic cognitive functioning, leading to better participation in therapy. To accommodate for cognitive deficits in attention, memory, comprehension, and planning, techniques to facilitate clearer communication and remembrance of therapy items are used (Morrison et al., 2004), consisting of simplification, emphasis, repetition, and feedback. Simplification involves using words and phrases familiar to a given person. If new terms are introduced, they are defined using familiar words. Homework exercises are spelled out in simple steps. Any explanation is broken down into understandable units. Important points are emphasized by getting the client’s attention with good eye contact, using their name, pausing (but not too long), and writing down what has been said. The writing is another form of repetition, which emphasizes important points. Writing occurs in session with whiteboards or paper. At the close of a session, assignments, summaries, and take-home points are written (or typed and printed) and given to the client to take home for easy referral. Clients comfortable with electronic technology can make notes on their devices for easy reference (i.e., alternative rational beliefs used on coping cards for situations eliciting common ATs/ABs). Client feedback is also a key ingredient to accommodate for cognitive deficits. Having clients repeat important information during a session, summarizations of sessions, and homework assignments at the end of a session help to reinforce information via repetition (and emphasis), while allowing the therapist to confirm comprehension of material. Overall, improvement in understanding and retention can increase their confidence in their own ability to engage in therapy. This leads to a decrease in demoralization and an increase in motivation.
CBTp AND MEDICATION Although CBTp reduces psychiatric symptoms in some people with psychosis choosing not to take medication (Morrison et al., 2014), medications often
Psychosis 271
provide relief and freedom from long-term hospitalization. Furthermore, many conditions with psychosis (i.e., schizophrenia, schizoaffective disorder, bipolar disorder, and in many cases, major depressive disorder) require ongoing medication to prevent relapse. Clients and their families may believe CBTp leads to no need for medication, but this is generally not the case. Although doses might be safely reduced, rarely can medication be stopped completely. On the other hand, in persons at high risk for psychosis, medication use is not justified because symptoms are not yet present. Studies have shown that the use of CBTp in high-risk populations prevents the onset of psychosis in many—thus eliminating the need for antipsychotic medication (Stafford et al., 2013). Nevertheless, this is different from treating those who have had “full-blown” symptoms. The use of medication is resisted for various reasons including (a) believing medication is only needed temporarily as with antibiotics; (b) noting symptoms do not return after medications are discontinued (until they finally do); (c) not being comfortable with needing medication—due to side effects, cost, stigma, and having to accept the presence of a persistent disease; and (d) poor insight (e.g., believing one has no problem, and therefore, one needs no medication). CBTp approaches are useful in examining the evidence for and against these beliefs as well as in aiding the decision-making process related to the risks and benefits of taking or foregoing medication. Persons may develop the belief that once symptoms resolve, medication is no longer needed, especially when symptoms do not recur for weeks after stopping medications. Because the beneficial effects of psychotropic medications tend to linger for at least a month after stopping them, symptoms later recur. Resumption of medication does not work quickly enough to avert problems from the symptoms. Moreover, insight into the recurrence of symptoms is limited, such that the person does not recognize the need to resume medication, which in turn further perpetuates the symptoms. Hence, hospitalization is often needed to bring about remission. CBTp approaches can increase insight into one’s condition, potentially leading to increased adherence. Insight is not always required for clients to want medication. For example, one person with the delusion of being possessed by demons believed medication helped to dispel them. Side effects and costs of medications can be serious deterrents to continuation of their use. The beliefs associated with these factors are valid. Physicians can discuss with clients the potential major side effects, presenting available options so choices can be made based on individual preferences (e.g., persons more sensitive to weight gain choosing a medication less likely to have that side effect) and being aware of and addressing socioeconomic obstacles. Physicians can address socioeconomic obstacles by informing persons of government-offered and pharmaceutical-sponsored assistance programs, or by providing coupons for and samples of medication. There are barriers to inexpensive access to medications, but feeling embarrassed to ask for help can be the first, toughest barrier. Finally, life-altering illness (especially involving mental health) and the devastation as well as the stigma involved can be a serious setback to self-esteem, especially with the tendency for these conditions to have their onset when one
272 Stolar and Wolfe
is beginning to start one’s independent life. It can take considerable time to decide that taking medication as a way to maximize one’s potential is preferable to being medication-free but burdened with significant, life-draining symptoms.
FAMILY INVOLVEMENT It is often difficult to conduct CBTp without involvement of family members (or agency staff if a person lives in a residential facility). Family members provide useful information that the client is not able to (or only with inaccuracies) regarding history, symptoms, progress, and treatment adherence (therapy as well as medication). This can go both ways for delusions. A person might state something as true that family members refute (e.g., having graduated from college). Alternatively, a claim that seems delusional may be confirmed by a family member. Families often need education about the nature (including prognosis) of the condition. Misinterpretations exist, a common one being mistaking negative symptoms for laziness (Pelton, 2002). Given that schizophrenia often starts with years of prodromal symptoms (e.g., declining cognition and motivation) and progresses past an active positive symptom phase to a residual phase with mainly negative symptoms, the chronic aspects of low motivation can be viewed by families as laziness when unaccompanied by the more pathognomonic positive symptoms. Families can aid therapy by assisting with completion of homework exercises. They may need education in the thin line between useful encouragement to engage in certain activities (including household chores) and “nagging” about lack of involvement. There is another thin line between refuting a person’s delusion and refusing to collude with it. A gentle admission that one does not share the person’s belief but respects that they do can go a long way. Families may find it confusing and frustrating to wonder how their years of refuting delusions is any different from a therapist appearing to do the same thing with CBTp. As above, differences of therapy include not being a family member (with emotional associations involved), the gradual nature of guided discovery, involvement of the client in looking for evidence and alternative explanations via the “Columbo” and other collaborative methods, the individualization of treatment with a focus on the client’s needs and goals, and the use of positive acceptance and regard. Teaching these to families help improve symptoms, quality of life, and the client’s sense of being heard.
EFFICACY As noted previously, beginning in 1978, a number of research groups in the United Kingdom initiated the formal use and investigations of CBTp, and continue to lead the endeavor (Wykes et al., 2008), which has spread from the United Kingdom to several countries, including but not limited to the United
Psychosis 273
States, Germany, Netherlands, Australia, Israel, Canada, and Italy. CBTp has been shown to be efficacious in treating the positive and negative symptoms of psychosis, mood, hopelessness, and overall functioning. More recently, CBTp has been used in the treatment of persons at clinical high risk (CHR) for psychosis (e.g., due to having first-degree relatives with schizophrenia) and has been found to be more effective in preventing transition to psychosis than TAU (van der Gaag et al., 2012), with results sustaining at a 4-year follow-up (Ising et al., 2016). Not only does the evidence show CBTp’s efficacy in CHR, prodromal phase (prior to onset of full symptomatology), first episode psychosis, and stable chronic symptoms (Birchwood, 2014), but also it has recently been found to lower ratings of positive and negative symptoms scores in those that are unmedicated (Morrison et al., 2014). Although more research is required on the predictive client characteristics and number of sessions required, it has been recommended as an adjunctive treatment to medication management by several entities including the Patient Outcomes Research Team (Kreyenbuhl et al., 2010), and the National Institute for Health and Care Excellence (NICE) guidelines—Psychosis and Schizophrenia in Children and Young People (Kendall et al., 2013), and Psychosis and Schizophrenia in Adults (National Collaborating Centre for Mental Health, 2014). Notwithstanding the above, reports of the efficacy of CBTp vary widely, especially considering differences among studies in the use of randomization of subjects, blind assessment of results, and therapy controls (e.g., supportive counseling) versus TAU. Initial summaries of CBTp studies reported results of individual studies (e.g., Haddock et al., 1998); later investigations used metaanalytic techniques (Burns et al., 2014; Jauhar et al., 2014; Jones et al., 2012; Lynch et al., 2010; Lutgens et al., 2017; National Collaborating Centre for Mental Health, 2009; Sarin et al., 2011; Tarrier et al., 2004; van der Gaag et al., 2014; Wykes et al., 2008; Zimmermann et al., 2005; see review Sivec & Montesano, 2012), mostly with small-to-moderate effect sizes (ESs; 0.20, 0.50 and 0.80 being small, medium, and large, respectively [Cohen, 1988], for positive, negative, and overall symptoms). In a comprehensive analysis of selected meta-analyses, Sivec and Montesano (2012) reported ESs for use of CBTp for positive symptoms ranging from 0.08 (for comparison to therapy controls at a 24-month follow-up; National Collaborating Centre for Mental Health, 2009) to around 0.30 (for studies with blind assessments; Zimmermann et al., 2005; Wykes et al., 2008). Regarding negative symptoms in studies in which blind assessments were used, ESs ranged from 0.04 (Jauhar et al., 2014) to 0.34 (standard mean difference; Lutgens et al., 2017). Again, limiting studies to those with blind assessments, ESs for overall symptoms ranged from 0.00 (Lynch et al., 2010) to 0.307 (Wykes et al., 2008). Possible reasons for the relatively low ESs include variability of experience using CBTp, small sample sizes (Lutgens et al., 2017), and variability in the treatment parameters (Wykes, 2014). What effects are pertinent can vary. Symptom severity, level of functioning, and quality of life are all reasonable foci of treatment. Client-defined goals may be viewed as an optimal category of measurement for effectiveness (Wykes, 2014).

MECHANISMS OF CHANGE Researchers have begun to examine what specific changes occur that account for the positive effects of CBTp. While proposed mechanisms driving change in CBTp have included reasoning processes (Garety et al., 2015), use of case formulation and homework (Flach et al., 2015), and alteration of negative asocial and defeatist self-beliefs (Beck et al., 2019) as mechanisms driving change in CBTp, the evidence remains unclear. For example, a study that directly measured mechanisms of change using mediation analysis (Mehl et al., 2018) to assess amelioration of delusions using CBTp found that neither changes in reasoning biases (i.e., jumping to conclusions, theory of mind, attributional biases) nor in self-schemas accounted for the effect on delusions. In a study using imaging to determine brain region changes associated with improvement with CBTp, Mason et al. (2016) found that reduction of positive symptoms correlated with increased connectivity between regions associated with higher order cognitive processes (potentially including cognitive appraisal) and a network involved with threat perception and salience (i.e., the importance of stimuli). This study suggests that cognitive reappraisal may be a mechanism of change for CBTp.
DISSEMINATION AND APPLICATION TO DIVERSE POPULATIONS Despite being recommended in the United States as treatment, adjunctive to medication, for individuals with both psychosis (Dixon et al., 2010; National Collaborating Centre for Mental Health, 2014) and early psychosis (Bertolote & McGorry, 2005), CBTp continues to be poorly disseminated, and training is limited (Kimhy et al., 2013). Kimhy et al. (2013) examined dissemination by surveying training directors in psychiatry residency and clinical psychology doctoral programs, finding limited knowledge of CBTp’s efficacy and little to no training opportunities within the programs. Given the present state of inadequate training opportunities and minimal dissemination in the United States, delivery of effective CBTp services to mitigate psychoses is very limited. A collection of CBTp experts across North America has existed for approximately 2 years. This group formally launched as the NA-CBTp Network in October 2018, opening up membership more broadly (K. Hardy, personal communication, September 10, 2018). Hardy et al. (2011) successfully developed a sustainable community early psychosis program in a nonuniversity health care setting in San Francisco County, California, called the Prevention and Recovery from Early Psychosis (PREP) program (Hardy et al., 2011). PREP clinicians received extensive training in evidence-based approaches and treated 30 clients and their families within the first year of operation. Implementation of this community-academic partnership program included extensive partnering with agencies acquainted with the local resources and helped bridge the gap between research and prac-
Psychosis 275
tice via successful integration of fidelity practice at the community level. More recently, Hardy et al. (2014) focused on the development of a sustainable “train the trainer” CBTp training and supervision model that could be implemented within a community-based service setting with predominantly master’s-level clinicians. This model included a 20-hour didactic training package, followed by weekly group supervision and monthly tape review. Persons trained to competence in the model became CBTp trainers and consultants. Community clinicians were trained to competence in CBTp utilizing this sustainable model. However, they encountered many obstacles throughout the development and implementation of the program, including staff turnover, resistance to implementation, recruitment of clinicians without basic background in CBT, language barriers, and delay in implementing skills in vivo due to gaps in establishing caseload (Hardy et al., 2014). Riggs et al. (2016), utilizing a pilot implementation project, demonstrated that staff in a high-demand, busy, real-world, public mental health system can learn and effectively implement CBTp achieving positive clinical effects. Moreover, Granholm et al. (2010) considered the feasibility of implementing CBTp in Assertive Community Treatment (ACT) teams and found that, whereas case managers can be trained to deliver CBTp with adequate fidelity, along with effective delivery from front-line workers, implementation barriers hindered the delivery of a sufficient amount of therapy (Granholm et al., 2010). Despite achievement of adequate fidelity ratings, key CBT skills were low in therapists with less than postgraduate education (this was with minimal, low-intensity training). Moreover, only 60% of therapists achieved adequate fidelity ratings, and only in at least one rated session. In reference to availability of CBTp services and trainings in the United States, there are some outlets that currently offer workshops and agency trainings, although they vary in applicability to outpatient and inpatient settings, milieu staff, and ACT teams. Yulia Landa is the program director for CBT for the Prevention and Treatment of Psychosis, a group- and family-based CBTp program for early psychosis (Landa et al., 2016). Landa also provides training in CBTp for mental health professionals working with psychotic disorders within the VA system (Landa, 2017). Aside from developing national strategies to increase dissemination of early psychosis models, with the aim of bringing these cutting-edge treatments to a broader population, Hardy also offers trainings and consultation in CBTp to a wide range of professionals. Riggs of NYC CBTp offers training workshops and consultations/supervision for both full individual and group therapy. Additionally, Riggs offers full CBTp trainings for agencies as well as CBTp-informed interventions for milieu working with psychosis. University of Washington’s Department of Psychiatric and Behavioral Sciences offers evidence-based trainings, including CBTp, for mental health providers working with persons with serious mental illness. In contrast to the United States, CBTp has been widely implemented and disseminated in Europe, especially within the United Kingdom, where it serves not only as a front line of therapy offered to persons experiencing psychosis
276 Stolar and Wolfe
(Wykes et al., 2008; Birchwood et al., 2014), but also in first episode psychosis (Bird et al., 2010) and as an early intervention service (van der Gaag et al., 2012; Ising et al., 2016). In South London and Maudsley, a clinical psychosis demonstration site used an approach from the U.K. National Health Service—Improving Access to Psychological Therapies for people with Severe Mental Illness (IAPT-SMI; Jolley et al., 2015). IAPT-SMI led to an almost three-fold increase in access to CBTp. Moreover, the protocol was found to be feasible and acceptable to service users, while boasting high completion rates and clinical improvement. Despite the success of such initiatives in Europe, implementation, training, and dissemination of CBTp in this country remain insufficient. A systematic review of 26 articles conducted by Ince et al. (2016) examined the implementation of recommended psychological interventions for schizophrenia, addressing rates, barriers, and improvement strategies. They found the estimated implementation range for CBTp from National Audits and Surveys in addition to local audits of services in different settings to be between 4% and 100%. Further, only one of the studies (Haddock et al., 2014) addressed quality assessment by using a design to minimize risk of bias to internal and external validity. Inequality in the provision of evidence-based therapies for persons with schizophrenia appears to continue notwithstanding our knowledge gains in this area. More recently, studies have examined feasibility, methodology, and cultural adaptability (Rathod et al., 2010, 2013) of CBTp trainings in countries such as Tanzania (Stone & Warren, 2011), Japan (Kikuchi, 2013), China (Li et al., 2017), India (Kumar, 2018), and Pakistan (Naeem et al., 2015, 2016).
CLINICAL EXAMPLE This example illustrates some CBTp techniques discussed in this chapter, including goal setting, normalization, voice content assessment, cognitive restructuring, coping tools for addressing auditory hallucinations, context elaboration (examining the context for logical conditions and outcomes), interventionist-causal approach to mitigating delusions and related distress, and guided discovery using the Socratic method. “Martha” is a 40-year-old woman who in her late 20s, while working as a clerk at an investment company after she graduated from college, began hearing voices and experiencing paranoia. Her symptoms worsened, interfering with her overall functioning and leading to the loss of her job. Her voices told her that people around her were saying negative things about her. Martha’s symptoms caused her significant distress whenever she was in public, which led to her avoiding crowded places and social interactions. Eventually, Martha’s decreased overall functioning and social isolation led her mother to move her back home and bring her to a CBTp therapist. Early in treatment, Martha and her therapist collaboratively outlined her treatment goals by breaking down her personal goals into achievable steps they could address together.
Psychosis 277
THERAPIST: Now that we’ve spent some time discussing what brought you
here, let’s talk about some of your goals and dreams. Imagine you aren’t experiencing any of the symptoms we’ve discussed and there are no obstacles present; what would you want to be doing with your life? MARTHA:
Well, if I could do anything in the world, I would want to be a famous movie star.
THERAPIST: What would you like the most about being a famous movie star? MARTHA:
If I was a famous movie star, I’d be really popular. I would be an important person and lots of people would look up to me. I would have a lot of friends. Being a celebrity, I could get into any restaurant I wanted to, and all of the guests would compliment my beauty.
THERAPIST: If you were a famous movie star, you’d be very well-known and
well-liked. People would look up to you, say nice things about you, and you’d have a lot of friends. Can you describe what being well-liked looks like for you? MARTHA:
If I were well-liked, then I would have a lot of friends. People would want to hang out with me, and we could do fun things together.
THERAPIST:
What would it mean about you if others are complimenting you?
MARTHA:
It would mean that I’m not disgusting and that I’m good at doing things.
THERAPIST: What would “being good at doing things” say about you? MARTHA:
Being good at doing things would mean I’m useful and can contribute in some way.
THERAPIST: That makes a lot of sense. How do you feel about yourself
right now? MARTHA:
I feel like I can’t do anything right anymore. I’m not useful or helpful in any way. I’m probably just an added burden to my mother and the people around me. I’m also really gross, so people don’t want to be around me because they think I am disgusting.
THERAPIST: Those sound like really hurtful feelings. How about we work
together to come up with treatment goals that get you closer to things you identified as wanting to experience such as being well-liked, having friends, going out to places you like, and feeling useful.
278 Stolar and Wolfe
The therapist and Martha spent the rest of the session discussing her experience being around other people and some of the beliefs that arise during those times. They also spent some time reviewing the CBT triangle and breaking down some of Martha’s thoughts into core beliefs. Martha had scheduled another session the following week. The following conversation took place during the bridge from the previous session: THERAPIST: Last week we spent some time discussing what it feels like to be
out in public around other people. I remember you were telling me about some of the things the voices say to you when you’re out in public. You said they tell you what people around you are thinking. MARTHA:
That’s right. The voices get really loud when I’m out around other people. Especially when there are big crowds. They say very mean things that other people are thinking about me.
THERAPIST: That would make going out to places very uncomfortable. MARTHA:
It is really stressful going out places where other people are since the voices get really loud and everyone is really mean to me. It makes me feel very uncomfortable.
THERAPIST: You try to avoid going out to places where others are unless you
absolutely have to. MARTHA:
Yeah. Sometimes my mom makes me go places with her and I feel so anxious the whole time. The voices start talking more and much louder when we are out in public. They even say nasty things to me when I am on my way to our appointments.
THERAPIST: Would it be helpful to be able to control the voices? Like being
able to turn the volume down on a stereo so you don’t have to hear a song? MARTHA:
It would be nice to be able to control them. Is that possible? How can you do that?
THERAPIST: It is possible, and we can work together on building skills that
can help you control the voices. The technique we are going to work on today is called “look, point, name.” What I want you to do is to look at an object in the room, point to it with your finger, and then say the name of the object out loud. I am going to go first and then I want you to try.
[THE THERAPIST LOOKS AT THE WINDOW IN THE OFFICE, POINTS TO IT, AND SAYS “WINDOW” OUT LOUD.]
THERAPIST: Okay, now it’s your turn.
[MARTHA LOOKS AT THE AIR CONDITIONER, POINTS TO IT, AND SAYS “AIR CONDITIONER” OUT LOUD.]
Psychosis 279
THERAPIST: Excellent! What were you thinking about when you were
engaging in this activity? MARTHA:
I wasn’t thinking about anything else besides the object I was looking at, pointing to, and naming in the moment.
THERAPIST: That’s how this technique can be helpful. This activity engages
different areas of your brain, which makes it hard to think about other things while you are doing it. When you look at something it is activating your visual system. Your motor system is activated when you point at the object, and then you use your memory recall and other parts of your brain when you name the object. Activating all of these different areas of your brain will help to turn down the volume and give you more control over the voices. It is much harder to concentrate on the voices when you are using your brain for all of the different types of activities involved in doing look, point, name. So, for your homework this week, I want you to practice using look, point, name, when the voices come up. Do it for as many rounds as it takes for them to quiet down, and record your experience with this coping technique to bring with you to our next session. Does that sound like something that would be helpful in getting closer to your goals? MARTHA:
I think having more control over the voices would be helpful. It would definitely make it easier to go places and be around other people since the voices wouldn’t be talking so loudly.
THERAPIST: It seems having control over your voices might make it easier to
go to places and be around other people since you won’t be hearing mean things other people might think about you. Martha continued to see her therapist for sessions regularly. In another session, Martha brought up an event that frightened her, MARTHA:
I was in bed and Steve Barnett from Community Clubhouse was there.
THERAPIST: He was in your room? MARTHA:
Yes. I didn’t see him, but I knew he was there.
THERAPIST: That must have been scary. MARTHA:
It was.
THERAPIST: Did you scream? MARTHA:
Oh, no. I did not.
THERAPIST: How did he leave? MARTHA:
I don’t know. He was gone.
280 Stolar and Wolfe
THERAPIST: And then you called the police? MARTHA:
No, I did not.
THERAPIST: You called for your mother? MARTHA:
I did not.
THERAPIST: You saw her at breakfast the next morning like you usually do,
correct? MARTHA:
Yes.
THERAPIST: What did you say to her about Steve? MARTHA:
Oh, nothing.
THERAPIST: You didn’t tell her that he got into your room? MARTHA:
No.
THERAPIST: That seems a bit unusual to not bring it up. MARTHA:
I suppose so.
Other times Martha brought up this type of delusion, the therapist would ask a few more questions examining logical conditions and outcomes. The therapist would ask only a few questions at a time to avoid interrogation as opposed to collaborative examination of the situation’s context. Other areas of inquiry included how Steve got into the house and Martha’s interaction with Steve the next day at the Clubhouse activities. The delusion was not questioned directly in terms of examining the evidence, and the therapist did not directly challenge any beliefs of Martha. Instead, questions concerning the context surrounding the delusional content were asked in an effort to elaborate the belief expressed in terms of logical conditions (e.g., Steve would have had to get in through an open door, someone letting him in, or by breaking in) and logical outcomes (e.g., Martha would likely have reacted to a real intruder by yelling, calling for her mother, calling the police, or at least letting her mother know about it). Martha’s belief in the delusion diminished as the logic behind it was gradually whittled away over the course of sessions. After some time, she started describing it in a subtly but significantly different manner: MARTHA:
Last night, it felt like Steve Barnett was in my bed again.
THERAPIST: Do you think he was really there or that it just felt like he
was there? MARTHA:
I just know that it felt that way—as if he was right there.
THERAPIST: Well, your feeling itself is real. You felt a sense as if he were
there. But you seem to recognize that just because someone has a feeling about something, does not mean it is true. The feeling
Psychosis 281
is true. You had that feeling. But, again, that does not mean that what you feel or sense is actually happening. Many can have a feeling that someone is angry at them, but that does not necessarily mean it is true. People often feel as if someone in a group of people is looking at them, but when they look around, they do not see anyone looking at them. MARTHA:
Yes, I had the feeling about it, but I did not find any evidence that he was there.
Eventually, the Martha did not bring up this delusion anymore. Throughout the course of treatment, it became evident that Martha’s negative self-beliefs and fear of negative evaluation had been perpetuating her experience of paranoia, voices, social avoidance, anhedonia, lack of motivation, and loneliness. Martha and her therapist broke down her goal of being a “famous movie star” into smaller, achievable treatment goals that hit on some of her personal values. This included Martha having control over her voices and other distressing symptoms, making friends, engaging in more activities at the places she wanted to go to, building skills that would make her feel “more useful,” helping others, and feeling better about herself (e.g., not feeling “disgusting”). Through discussing the content of her voices and fears of negative evaluation from others, Martha and her therapist were able to identify some of her pervasive negative beliefs about herself (e.g., “I am disgusting,” “I am useless,” “I am unlikable,” “I am a failure”) and then subsequently use the CBT techniques of cognitive restructuring to replace them with more accurate and adaptive beliefs (e.g., “I am competent,” “I am likeable”). On the basis of the information Martha provided throughout their sessions, the therapist identified negative self-concept, low self-esteem, fear of negative evaluation, and worry to be primary issues impacting Martha’s symptomatology. As such, the therapist used the interventionist causal approach to CBTp (focusing on and targeting factors involved in the formation and maintenance of delusions) to address Martha’s paranoia and suspiciousness via engaging Martha in interventions and activities that targeted her negative self-evaluation and worry. That is, as Martha’s self-concept became more positive, fear of negative evaluation and worry decreased, and her experience of paranoia and suspiciousness began to dissipate.
CONCLUSION CBT expanded from its original use for treating depression to encompass a vast array of mental health conditions, including the challenging state of psychosis, found in a number of conditions, most notably schizophrenia. The basic tenets of examining the evidence and alternative explanations for events, interpreted by these persons in ways that stretch logic beyond what most of us would
282 Stolar and Wolfe
consider veritable, are viable methods even in these extreme cases. The definition of delusions as “firm, fixed beliefs” breaks down as this approach continues to help people question these beliefs and, at times, abandon them. In addition to addressing delusions, CBTp is used to alter beliefs about the power, nature, and content of voices; beliefs leading to bizarre behavior; beliefs that lead to stress exacerbating (or producing) disorganization of behavior and speech (the latter manifesting as FTD); and dysfunctional beliefs leading to negative symptoms. The effectiveness of CBTp has been called into question by rigorous analyses that require treatment controls (such as supportive counseling) and blind assessments when conducting meta-analyses. Although this evidence-based view is scientifically sound and helps prevent claims of treatment effectiveness that are not justified, there are limits to how well the evidence-based approach mirrors the clinical values of a given therapeutic method—specifically in three areas. First, by requiring CBTp outcome studies to have therapy controls, CBTp has to not just be shown to be effective, but it has to be statistically significantly more effective than other forms of therapy. This would be optimal, but is it fully necessary? CBTp was shown in Lynch et al. (2010) to usually be better than therapy controls, but not with a statistically significant difference. This would be important if it was significantly more expensive than other forms of therapy, but other than the initial cost of training a therapist in CBTp, there is usually no ongoing substantial cost difference. If parents are told that CBTp is better than other forms of therapy, but not statistically significantly better, and has a similar cost, they are likely to request it. Secondly, statistical analyses rely on means. With medications, maximum doses are sometimes determined by studies showing that, on average, people taking a medication will not do any better above the maximum dosage. However, there are a good number who do better, if needed, at the higher dose, so many physicians base their practices on experience and will prescribe the higher doses. This is an illustration of the principle of individualized treatment. Again, with most studies showing better outcomes for CBTp in the Lynch et al. (2010) analyses (but not statistically significant better), most individuals likely did benefit from the treatment beyond what other forms of therapy would do. A lesser number would have done no better, and an even lesser amount might have done worse than if they had another form of therapy. A better approach than dismissing CBTp as not effective enough is to determine which individuals are the ones who would benefit from CBTp—much as genetic analyses are being used more frequently to determine which medications work best for which clients, as often a client has to try many of them before finding one that works well enough. Finally, and perhaps most importantly, is how outcome studies depend on what measures of effectiveness are chosen. Usually symptom reduction and functioning are measured. Quality of life is sometimes used. These are important yardsticks, but when a parent says that no one else has connected as well
Psychosis 283
with their adult child; when the person comes back to therapy again and again after leaving other attempts at treatment; when a person can have their beliefs addressed instead of merely medicated, listened to, and examined; and when the emotional anchors holding those beliefs in place are addressed, then perhaps additional measures need to be considered—ones that demonstrate the value of seeking to objectively learn another’s reality.

efore outlining cognitive behavioral therapy for insomnia (CBT-I) and the evidence surrounding its efficacy and effectiveness, it is important to provide, albeit briefly, a working definition of insomnia. This not only provides a context from which we can examine CBT-I and its central components, but it also gives an insight into what outcomes, in terms of its symptom profile, CBT-I is aiming to address.1,2,3 Insomnia has been conceptualized in many different ways since its inclusion in the ninth edition of the International Classification of Diseases (ICD) in 1977. Since that time, iterations of what determines a case of insomnia have changed between, and within, three main nosologies: the ICD, the Diagnostic and Statistical Manual of Mental Disorders (DSM), and the International Classification of Sleep Disorders (ICSD). There are, however, some core features that have Throughout this chapter, cognitive behavioral therapy for insomnia will be referred to as CBT-I. This is partly because it is a standard acronym by which to refer to the treatment. As or more important, the acronym suggests that this is one form of CBT-I (one protocol), where there are many others (e.g., CBT-D for depression, CBT-A for anxiety, etc.). Although this kind of “naming” runs countercurrent to the “transdiagnostics” movement, it has the advantage of identifying the treatment protocols that are specific to the particular brand of CBT. Because the term “insomnia” has both formal and informal denotations, problems falling and staying sleep will also be referred to as “sleep continuity disturbance.”

both united these nosologies and stood the test of time. Predominately the principle complaint—of a self-reported difficulty in initiating and/or maintaining sleep—has remained constant. Additionally, albeit qualitatively and quantitatively different at times, the inclusion of minimum frequency, duration, and an impact criterion have also united these nosologies. Insomnia disorder, at least within the ICSD-3 and DSM-5, is predicated on the basis of a principle complaint of a difficulty getting off to sleep (initial insomnia), difficulty staying asleep (middle insomnia), and/or waking up earlier than required or desired (late insomnia) and should exist despite having adequate opportunity to sleep. Interestingly, there are no formal criteria for severity. That is, there is no definition for what “difficulty” initiating and maintaining sleep means. In other words, how much time needs to pass for it to be considered a problem? Although there are no formal definitions, there seems to be clinical consensus that suggests any amount of time greater than 30 minutes starts to frame the problem. Further, the difficulty should occur for at least three nights per week, have been present for at least three months, and cause—again within the context of self-report—significant distress and/or impairment to daytime functioning. One of the most significant advances in the area of defining insomnia, however, has been the reconceptualization of insomnia as a disorder, outlined in the fifth edition of the DSM (American Psychiatric Association, 2013) and the third edition of the ICSD (American Academy of Sleep Medicine [AASM], 2014). Previously, if insomnia was observed alongside another illness, disease, or disorder it was classified as secondary insomnia, with the assumption that if the other illness were managed the insomnia would resolve naturally. This change to a primary insomnia (where only insomnia is present) versus a secondary insomnia classification system continues to challenge the traditional viewpoint of insomnia and, indeed, all general forms of sleep disruption. Insomnia should no longer automatically be considered a symptom of another illness, disease, or disorder but instead a disorder in its own right, regardless of what comorbid disorders occur alongside the insomnia (unless a compelling case can be made for contingency—termed “adequately explained” in the DSM-5). This not only has ramifications for how insomnia is regarded by the healthcare profession but also mandates that chronic insomnia (i.e., insomnia disorder) be targeted for independent treatment and opens up the possibility that such treatment may have positive clinical effects on other disorders. The determination of whether a comorbid condition adequately explains the insomnia, however, is largely in the eye of the beholder. It remains easy for any clinician to assume that the insomnia is explained simply by the presence of the other illness. This is what continues to be the problem, which will not be solved until it becomes clear to the clinician that once perpetuating factors take hold the insomnia has taken on a life of its own and will not likely remit with targeted treatment for the “other” condition. Although definition is paramount, it is important, at least for our later understanding of why CBT-I may be considered a suitable candidate treatment for
Insomnia 293
insomnia disorder, to understand how and why insomnia develops. Arguably the most influential framework for understanding the development of insomnia came from Spielman and colleagues (Spielman, 1986; Spielman, Caruso, & Glovinsky, 1987). According to Spielman, the course of insomnia is comprised of three factors: predisposing factors, precipitating events, and perpetuating factors (see Figure 9.1—the 3P model of insomnia). Whereas predisposing factors include anything underlying that may increase the likelihood of insomnia occurring when the individual is under challenge or threat, the actual stressor or trigger itself is considered the precipitant event, responsible for initial insomnia, otherwise known as acute insomnia. As can be seen in Figure 9.1, over time the impact of the stressor dissipates. That is not to say that the stressor, which Spielman conceptualized as a significant life event (e.g., bereavement, divorce, an illness)—although this viewpoint has been challenged more recently (see Ellis et al., 2012; Morin et al., 2003)—has been overcome, per se, but the stress response, largely biological in nature, fueling the initial period of insomnia has reduced. Most importantly, it is the perpetuating factors, which develop during the acute phase and grow in strength and importance over the course of insomnia, that are considered to be the drivers of the insomnia through its acute to chronic phase (Spielman, Caruso, & Glovinsky, 1987). These perpetuating factors, according to Spielman and others around the same time, such as Bootzin (1972), focused largely on the behaviors by which the individual attempts to cope or compensate for this initial period of insomnia and its resultant impact on daytime functioning. Perpetuating factors include drinking caffeine or napping during the day to counteract daytime tiredness, drinking alcohol to get off to sleep at night, and/or engaging in behaviors in the bedroom, such as watching television or working, when unable to sleep.

Whereas caffeine has the potential to keep us alert when we should or would want to be sleeping, alcohol is likely to decrease the amount of time it takes to fall asleep but increase the likelihood of fragmented sleep and nocturnal awakenings. Both strategies are therefore incompatible with sleep. Further, activities in the bedroom, other than sleep or sex—which is good for sleep—are likely to condition the bedroom to be a place for wakefulness by blurring the lines between daytime and nighttime activity whilst increasing arousal at night. The perpetuating factor believed to have a substantive impact on the course of insomnia, however, is spending excessive time in bed, either by going to bed early, lying in bed in the morning, or napping in the daytime (Spielman, Saskin, & Thorpy, 1987). Here, the belief is that any of these behaviors can reduce the drive to sleep at night, desynchronize the circadian rhythm for sleep, and have the capacity to fragment sleep. Further, this excessive time in bed is likely to create a scenario in which sleep-related stimuli become conditioned stimuli for wakefulness (i.e., bedroom, bed, and bedtime elicit the physiology of wakefulness and potentially negative affective states). Although the later models of insomnia (e.g., Buysse et al., 2011; Espie, 2002; Harvey, 2002; Morin, 1993; Perlis et al., 1997) still acknowledge the central role of the aforementioned behavioral factors in the perpetuation of insomnia, they also began to stress the importance of neurocognitive and neurobiological factors. Based upon phenomenological studies on individuals with insomnia, concepts such as “the racing mind,” the inability to “switch off,” and sleep-related attentional and interpretative biases were found to be common features amongst individuals with insomnia (Barclay & Ellis, 2013; Ree & Harvey, 2006; Wicklow & Espie, 2000). Thus, factors such as sleep-related dysfunctional beliefs, catastrophic worries over the short- and long-term consequences of poor sleep, sleep effort, and sleep preoccupation were seen as additional factors that could also perpetuate insomnia and would need addressing within a treatment framework (Ellis et al., 2007; Lichstein & Rosenthal, 1980; Morin et al., 1993). More importantly, and in some cases more implicitly, the newer models began to suggest that insomnia should be seen as a 24-hour disorder whereby actions, thoughts, and feelings during the day can influence sleep at night. In essence, if these perpetuating factors (both behavioral and cognitive) are the main issues fueling the chronic version of insomnia, then it stands to reason that their removal or successful management is likely to resolve or significantly ameliorate the insomnia. This rationale fits with the premise of CBT-I as a multicomponent treatment strategy that addresses both sleep-related cognition and behavior.
CBT-I AND ITS COMPONENTS The first thing to note about CBT-I is that it currently has no formal standardization. The length, number of sessions, and even the guidance on each component, including the order of delivery, differs among manuals, research
Insomnia 295
protocols, and clinicians. That said, in the majority of cases, each session will generally be around 45 to 60 minutes in duration and occur over the course of 6 to 8 consecutive weeks. The first step in the treatment sequence is a thorough assessment. This initial evaluation aims to (a) ensure the individual has a form of insomnia that is amendable to CBT-I (e.g., not the sleeplessness associated with circadian rhythm disorders) and (b) take into account complicating factors related to comorbidities, substance use, current medication regimens, and/or life circumstances. The initial evaluation should also include assessment directed at uncovering the presence and type of perpetuating factors that may be involved. Immediately following the assessment is a period of baseline monitoring of sleep for between 1 and 2 weeks. This monitoring entails the prospective continuous sampling of sleep continuity data via the completion of daily sleep diaries. Sleep diaries, it should be noted, are critical to the conduct of CBT-I and are required for the duration of therapy. Sleep Diaries The sleep diary collects information, via self-report, regarding the timing, quantity, and quality of sleep. To be completed every morning, shortly after awakening, the information gathered from the sleep diary is usually summarized over the course of a week. The core sleep diary queries include time in and out of bed (TTB and TOB), sleep latency (SL), number of awakenings (NWAK), and time spent awake after sleep onset (WASO). These variables allow for the calculation of several additional metrics including total sleep time (TST), time in bed (TIB), and sleep efficiency (SE), the latter variables being essential for the conduct of CBT-I, or at least the component referred to as sleep restriction therapy. Although there are many sleep diaries available (which vary in both content and format), there is a consensus sleep diary (Carney et al., 2012), and this particular format is the one that is recommended here (see Table 9.1). These dimensions map on to the core symptoms of insomnia and are used both to inform treatment recommendations, as will be seen later on, as well as to TABLE 9.1.

provide an indicator of treatment success. Importantly, sleep diaries can also provide a gross measure of adherence to the behavioral components of CBT-I. More recently sleep/activity trackers have been suggested as an alternative to self-report sleep diaries. Although these devices are helpful in some circumstances (e.g., where there are practical limitations to completing a self-report sleep diary or potentially to detect a form of sleep continuity disturbance— problems initiating or maintaining sleep—known as paradoxical insomnia), questions remain about their validity when used in place of sleep diaries in patients with insomnia (Kang et al., 2017). One of the main issues usually raised by the individual with insomnia, in the context of sleep diaries, is clockwatching. It is important to advise the individual not to have a clock face visible in the bedroom, as this can lead to clockwatching (i.e., calculating how long individuals have been asleep and how long they have remaining before they need to get up) throughout the night, which can increase anxiety about the consequences of poor sleep on daytime functioning, thus further delaying sleep onset. So how are individuals with insomnia going to complete a sleep diary if they do not have a visible clock from which to work? This is an interesting question and one that various therapists probably approach differently. One suggested way forward is to discuss the relevance of the subjective complaint (i.e., the reason they have come for CBT-I) over the issue of objective sleep. It is also essential to emphasize with the patient that clinical experience has demonstrated that, in most cases, subjective impressions are reasonable “ballpark” estimates that will be close enough to guide appropriate treatment choices. Psychoeducation (Including Sleep Hygiene) The main premise of psychoeducation is to begin to address the individual’s preconceptions and expectations about sleep, such as how much sleep an individual needs (including intra-individual differences), some basic sleep architecture constructs, how sleep changes over the lifespan, what insomnia is, and why it occurs. Addressing these issues affords the individual an understanding that there is no nomothetic rule with regard to sleep need and that insomnia, in its initial presentation, is a normal biological reaction to stress. Further, this latter assertion affords a discussion of the role of perpetuating factors using Spielman’s model, how these can maintain insomnia, and consequently, why CBT-I is an appropriate treatment strategy. Within this session, the basics of sleep physiology are also likely to be discussed, usually with reference to Borbély’s two-process model of sleep, which defines sleep regulation in terms of circadian and homeostatic factors (see Borbély, 1982). According to Borbély’s model, the circadian rhythm is the internal biological clock that regulates the timing of sleep, largely evidenced through the production and suppression of melatonin and changes in body core temperature, whereas the sleep homeostat (i.e., drive) regulates the propensity to sleep through a biochemical system that starts on termination of the prior sleep
Insomnia 297
episode and continues until the next sleep episode occurs. The relevant points to note in this discussion are that (a) the homeostatic drive to sleep will continue to build until sleep occurs and (b) the circadian timing for sleep remains relatively constant whether we sleep or not. The first point allows for a discussion regarding night to night variability in sleep, in that individuals with insomnia will have the “odd” reasonable night of sleep because the drive to sleep is so high, and the second point allows for a discussion of why people are likely to feel particularly drowsy at certain times of the day, irrespective of how much sleep they have obtained (Perlis et al., 2010, 2014; Vallières et al., 2005). Additionally, providing an overview of this model affords a discussion on the way in which behaviors such as napping and spending excessive amounts of time in bed can weaken the sleep drive, making it difficult to sleep at night, and the way in which both variability in sleep schedules and the timing of other activities, such as eating and exercising, also have the potential to desynchronize the circadian system. It is helpful to underscore that such disruptions help explain why the individual’s sleep problem remains relatively consistent despite the fact that the original stressors that brought about the insomnia initially have long since abated. The second aspect of psychoeducation is sleep hygiene, which refers to a set of guidelines regarding the optimal sleep environment and routine, as well as lifestyle factors and habits that can impact on sleep. As with CBT-I, there is no standard set of guidelines; however, common aspects include (a) limiting or avoiding alcohol, caffeine, and nicotine in the evening; (b) ensuring that the bedroom is conducive to sleep (i.e., cool, dark, and quiet; removal of electronics from the bedroom); (c) not going to bed hungry or thirsty, but also not full up; and (d) using exercise to promote sleep, although exercise is not advocated in the later part of the evening due to its capacity to desynchronize the circadian rhythm (Morin, Hauri, et al., 1999). When considering the AASM’s Practice Parameters for the treatment of insomnia (Morgenthaler et al., 2006; see Table 9.2), one will note that sleep hygiene is not endorsed as a standard or guideline treatment on its own, but instead as part of a multicomponent treatment. The rationale for this is that studies that have examined differences between individuals with insomnia and normal sleepers in terms of levels of sleep hygiene practices have been equivocal, at best (Jefferson et al., 2005). In fact, several studies have shown that individuals with insomnia demonstrate a better awareness and practice of sleep hygiene than normal sleepers (Lacks & Rotert, 1986; Gellis & Lichstein, 2009). The final aspect of this session is likely to revolve around what CBT-I is and the individuals’ expectations from it. Many individuals with insomnia expect to be sleeping longer by the time they have completed treatment, when TST does not tend to significantly increase during acute treatment. The central aim of CBT-I is to reduce the amount of time awake during the night while simultaneously increasing the quality of the individuals’ sleep. To clarify this point, it is helpful to ask the individual to think of nights where they have slept for a long time and not felt refreshed and, conversely, nights in which they have had

fewer hours of sleep but woken feeling refreshed and alert. That said, individuals can be assured that if they continue to practice what they have learned in therapy, they can expect to slowly increase TST to more optimal levels over time.
Sleep Restriction Therapy (Restriction and Titration) Restriction The term sleep restriction therapy is a misnomer, as it is not the intention, or practice, of this protocol to restrict or reduce the amount of sleep an individual is achieving, per se (Spielman, Saskin, & Thorpy, 1987). The aim is to match sleep opportunity (i.e., amount of time in bed) to sleep ability (i.e., the amount of sleep the individual can generate) while simultaneously adding pressure to the sleep drive. This is achieved by restricting the amount of time that is allowed in bed, using the pretreatment sleep diary as a guide. As noted previously, the sleep diary provides information on how much time individuals perceive they are sleeping (TST) and how much time they are spending in bed (TIB). The initial goal of sleep restriction is to reduce TIB so that it is in alignment with TST. It is important not to reduce TIB too far, so if an individual with insomnia reports sleeping less than 5 hours on average, then a 5-hour minimum TIB is usually set (Spielman, Saskin, & Thorpy, 1987). Setting the timing of this new sleep schedule with the individual can be challenging, but the discussion generally focuses on what time the individual needs to be up in the morning.
Insomnia 299
Setting the new sleep schedule “prescription” based upon wake time (i.e., the anchor time) serves two purposes: (a) a regular morning routine strengthens the sleep drive and places it roughly in alignment with the circadian rhythm, and (b) it limits interference with the individual’s life circumstances (e.g., getting up for work, getting the children ready for school), increasing the likelihood of adherence. Once the anchor time is set, the time to bed can also be calculated and set by working backward (e.g., “If I am getting up at 7 a.m., and my TST is on average 6 hours, then I will go to bed at 1 a.m.”). This “prescription” is adhered to (both in terms of time to bed and time out of bed) for the next 7 days or until the next appointment. Serious session time must be devoted to helping individuals devise ways to deal with obstacles to adherence (e.g., difficulty staying awake until the prescribed bedtime, waking up and getting out of bed at the prescribed wake time) at this juncture. Titration At the next session and over the subsequent weeks of treatment, the initial prescribed sleep schedule is titrated on the basis of the individual’s SE, from the most recent 5 to 7 days of sleep diary data. As seen in Table 9.2, the sleep diary can be used to create an index of SE with the equation: TST/TIB*100. Based upon the average SE, the rules of titration in most cases are then introduced: (a) if SE is less than 85%, then the amount of time allowed in bed is reduced (usually in terms of going to bed later) by 15 minutes; (b) if SE is between 85% and 89% then, the prescription stays the same; and (c) if SE is 90% or above, then the amount of time allowed in bed is increased (usually in terms of going to bed earlier) by 15 minutes (although there are some therapists who increase time in bed based upon a SE of 85% to increase the chances of adherence). Importantly, the 5-hour minimum is still in effect, as it is throughout the entirety of CBT-I, so if the calculations suggest that titration should go below 5 hours, then the 5-hour minimum is still used. The rationale for the 5-hour minimum is that at least for the first week of treatment the individual may still have sleep initiation or maintenance difficulties, and a buffer of 5 hours is needed to ensure unmanageable levels of sleep deprivation are not induced. It is important to tell individuals being treated that they are likely to experience higher levels of sleepiness, albeit for a brief period; otherwise, they may interpret the increased sleepiness as treatment failure and discontinue treatment. Caution must be taken to discuss the possible exacerbation of short-term sleepiness, and work is needed to come up with strategies to stay safe during the day (e.g., taking safety naps, considering alternative modes of transportation to driving). Stimulus Control (Standard, Exceptions, and Managing Time Out of Bed) Standard Developed by Bootzin (1972), stimulus control aims to address the conditioned arousal that has developed over the course of insomnia. It is common for individuals with insomnia to state, for example, that they frequently “nod off” on the sofa in the evening, but that when they approach the bedroom or start their
300 Ellis, Perlis, and Posner
normal bedtime routine (e.g., brushing their teeth), they become fully awake and alert and, thus, are unable to sleep. Moreover, many people with insomnia, when asked about their bedroom, are likely to respond negatively, stating that the bedroom and bed are a source of worry, anxiety, frustration, or anger. Naturally, being alert, anxious, worried, frustrated, or angry in bed is going to be incompatible with sleep. In order to break the association between the bedtime routine and the bedroom and wakefulness, as well as reestablish the bedroom as a place for sleep, Bootzin outlined a series of instructions relating to the bedroom environment and managing periods of being awake during the night. As can be seen in Figure 9.2, put simply, the instructions ensure that any time awake is spent outside of the bedroom and any time sleeping is spent in the bedroom, with the bedroom being optimally conditionable for sleep. This latter presentation also starts to address another insidious perpetuating factor—sleep effort. Most good sleepers cannot explain what intentional actions they take to get to sleep. In other words, they do not attempt to empty their minds, change breathing patterns, or relax muscles, much less toss and turn in order to achieve the right position to achieve sleep. Individuals with insomnia often perform all of these “efforts” to obtain sleep. Being told to get out of bed as soon as one becomes aware of being awake and engaging in any of these actions begins the process of helping the individual to let go of sleep effort, wait for sleepiness, and to get back into bed when sleep is more likely to unfold naturally without effort.
FIGURE 9.2. Bootzin's Instructions
STIMULUS CONTROL INSTRUCTIONS 1. Lie down to go to sleep only when you are sleepy/sleep only in the bedroom. 2. Do not use your bed for anything except sleep and sex. 3. If you find yourself unable to fall asleep, get up and go into another room. Stay up as long as you wish and then return to the bedroom to sleep. 4. If you still cannot fall asleep, repeat step (3). 5. Set your alarm and get up at the same time every morning irrespective of how much sleep you got during the night. 6. Do not nap during the day.
Insomnia 301
Exceptions As can be imagined or foreseen, there are inevitably circumstances whereby it is impractical for an individual to leave the bedroom or, indeed, the bed. These factors include frailty and the risk of falls, physical disabilities, and/or the bedroom environment itself (e.g., a bedsit, prison), for example. In these instances, counter control may be employed as an alternative. In this case, the individual remains in the bed, but one side of the bed is designated as an “awake” zone, and the other side is the “sleep” zone. In the “awake” zone, the individual can engage in wake-like activities, but there should be no intention to sleep (i.e., no sleep effort). Although limited, the studies that have utilized counter control have shown good efficacy comparative to traditional stimulus control (Hoelscher & Edinger, 1988; Zwart & Lisman, 1979). Managing Time out of Bed One of the main issues raised following both sleep restriction therapy and stimulus control is what can the individual do during those times out of bed. Maintaining good sleep hygiene is advocated, and the individual is usually instructed to engage in activities that are not physically or psychologically arousing. However, if the individual is devoted to getting out of bed and just sitting in the dark and waiting anxiously to return to bed, this should be seen as another type of sleep effort and a misunderstanding of how stimulus control works. It is important from the outset that the individual understand that the reconditioning that is expected with stimulus control cannot be achieved in a single night and may take several weeks of consistent application to help change the bedroom and bedtime experience back into conditioned stimuli for sleepiness and sleep. Therefore, any given night is to be sacrificed for improvement in the long term. It is important to work with the individual to make a list of activities they can do out of bed aimed at enjoyment and relaxation. This is why, on any given night, individuals need not worry about whether they can get back to sleep that night and why they need not fear engaging enjoyable activities (e.g., watching movies, reading good books, doing favored hobbies or crafts) at night. Relaxation Therapy The most evidence for relaxation therapy, used within the framework of CBT-I, has been from studies employing either progressive muscle relaxation (PMR) or biofeedback (Chesson et al., 1999; Freedman & Papsdorf, 1976; Morgenthaler et al., 2006). In fact, both strategies are endorsed, as was seen earlier, by the AASM. Other forms of relaxation, such as meditation, autogenic training, and imagery training, have also been used, but there is at present limited evidence for their efficacy. Irrespective of the type of relaxation employed, the aim is to reduce somatic tension either prior to or in bed by having the individual focus on their state of physical arousal. That said, there is limited evidence that this is the mechanism by which they work. It could equally be suggested that they work through cognitive distraction, limiting the racing mind and catastrophic
302 Ellis, Perlis, and Posner
thinking. PMR instructions suggest the individual start at the head and tense the muscles in that region, hold that tension for a few seconds, then release, and then progressively move all the way down the body, whereas biofeedback involves monitoring objective physiologic signals and identifying and self-modulating any signs of tension. Whereas PMR is a simple technique that can be employed by the individual at their leisure, the main challenge with biofeedback is that it is a resource intensive, time-consuming, and expensive procedure. Thus, biofeedback is rarely used in clinical practice. Cognitive Therapy Probably the component that most speaks to the lack of standardization is cognitive therapy, with several techniques currently being employed and with some protocols not including any form of cognitive therapy at all. In fact, as we saw earlier (Table 9.2), a cognitive component is not necessarily required for CBT-I by the AASM. The four main types of cognitive therapy used within the context of CBT-I are outlined in Table 9.3 alongside their aims and brief instructions (for full instructions see Espie & Ellis, 2016). Although dysfunctional cognitions are thought to influence insomnia primarily through worry and anxiety (i.e., a hyperaroused state), they are also likely to influence sleep-incompatible behaviors. For example, the belief that the individual needs 8 hours of sleep to TABLE 9.3. Overview of Cognitive Therapies for Insomnia Cognitive therapy

function or that sleeping badly one night can significantly impact on next day’s performance are likely to result in excessive time being spent in bed and the use of stimulants throughout the day. Two additional cognitive strategies are setting a wind-down time and practicing worry time. A wind-down time involves simply setting a time after which the individual sets aside arousing activities such as work, emails, and planning for the next day and instead begins to engage in more relaxing activities leading up to bedtime. Worry time is utilized when the individual with insomnia regularly complains of mind racing, worries, and thoughts about planning for the next day interfering with sleep onset and/or maintenance. The technique involves instructing the individual to set aside a dedicated period of time during the day (perhaps as short as 15 minutes) to actively plan or address worries that are bothering them. The rationale is that such a strategy can help shift the need for such problem solving from the night to the day. Regular practice can help the individual to avoid efforts to suppress such thinking at night (another form of sleep effort) and postpone these thoughts to a more appropriate time of the day. A recent study by Harvey et al. (2007) used a cognitive intervention alone to see its impact on insomnia. The aim was to address the five cognitive factors that she proposed to maintain insomnia in her earlier model (Harvey, 2002). The intervention contained three elements: case formulation (i.e., identifying cognitive factors perpetuating the insomnia), personalized experiments with guided discovery (i.e., devising and instigating behavioral experiments to challenge dysfunctional cognitions with the help of the therapist), and relapse prevention in order to identify and manage (a) worry and rumination, (b) attentional biases toward sleep-related cues and sleep-related threat monitoring (e.g., monitoring for physical signs of wakefulness at night), (c) dysfunctional beliefs about sleep, (d) the use of safety behaviors (e.g., canceling engagements due to perceived tiredness), and (e) misperception of both sleep and daytime deficits (e.g., attributing “normal” variations in daytime sleepiness to the insomnia). Although preliminary, the results showed continued sustained treatment gains in terms of self-reported sleep and on the Insomnia Severity Index (ISI; Morin, 1993) posttreatment and up to a year later (i.e., moderate to large effects in terms of reductions on SL, WASO, and ISI scores and increases in SE). Paradoxical Intention Paradoxical intention is the only “cognitive” therapy that is endorsed by the AASM. Its application to the treatment of insomnia is based on the premise that trying to sleep is counterproductive, and the effort expended trying to sleep is likely to result in keeping the individual awake feeling angry, frustrated, and/or worried (Espie et al., 2006). The instructions for paradoxical intention involve the individual getting everything ready for bed, as normal, including getting into bed and switching off the lights. With their eyes open, individuals are then instructed to remain quietly awake, periodically congratulating themselves on being able to passively resist sleep. This should continue until sleep has been
304 Ellis, Perlis, and Posner
achieved. Although not well studied, the rationale for its success is believed to be through reductions in sleep effort and the resultant physical and psychological tension when sleep effort does not pay off and the individual tries harder to sleep. Mindfulness-Based Approaches Although not strictly a cognitive therapy, more recently the principles of mindfulness have been introduced into existing CBT-I, with some excellent results (Ong, Shapiro, & Manber, 2008; Ong et al., 2009, 2014). For example, Ong et al. (2014) demonstrated a 78.6% treatment response rate, significant reductions in the amount of time spent awake at night, and a long-term (12 months posttreatment) effect size of 2.56 on the ISI. Mindfulness, as applied to insomnia, differs from the other cognitive therapies in that instead of identifying and addressing dysfunctional cognitions, the individual acknowledges any thoughts or attributions related to sleep or thoughts of any nature over the sleep period. Several techniques are applied to how sleep and insomnia are viewed—nonjudging (i.e., understanding that being awake at night is not automatically a negative occurrence), beginner’s mind (i.e., treating each night as just that, a single night), nonstriving (i.e., not trying to sleep at night or hiding your feelings of sleepiness during the day), acceptance (i.e., accepting the present state of wakefulness), letting go (i.e., not trying to change the content of sleep-related thoughts), trust (i.e., believing one’s sleep system can and will eventually reset), and patience (i.e., acknowledging getting sleep back on track will not happen overnight; Ong et al., 2012). One of the drawbacks of this approach, however, is that it appears that a great deal of training and practice is required to master the approach. Relapse Prevention Rarely discussed in the literature is relapse prevention, despite the fact that many clinicians use the final session of CBT-I to address this. Going back to Spielman’s 3P model, although CBT-I does not really consider predisposing factors and precipitating events in its main formulation, addressing these issues could be considered helpful at this point. For example, identifying the ways in which the individual is vulnerable to insomnia and the kinds of precipitating events that triggered insomnia previously, as well as the types of coping strategies used that were unhelpful in the past, may provide useful insights to prevention or early management of a future episode (Drake et al., 2014). In addition, once the individual is sleeping well, the amount of sleep restriction is reduced, and stimulus control is rarely needed. However, the individual should be alerted to the fact that bouts of acute insomnia are inevitable, and that re-application of stimulus control and sleep restriction can help to avoid more chronic insomnia. One final consideration at this point is regarding increased vulnerability. Although there is evidence that suggests that having a prior episode of insomnia confers a significant risk for a future episode (Jarrin et al.,
Insomnia 305
2014; Morin et al., 2009), it should be borne in mind that the initial phase of insomnia (i.e., from onset to 2 weeks) may in fact be a normal biological reaction to a stressor (Perlis et al., 2016). Thus, during this period no intervention is required beyond telling the individual not to engage in compensatory practices and sleep-related effort during that period.
CANDIDATES FOR CBT-I The main consideration for candidacy for CBT-I has been the sleep deprivation, albeit brief, created by sleep restriction therapy and stimulus control. Candidacy has primarily focused on two areas—occupational issues and illnesses, diseases, or disorders (including medications), which may be affected by sleep deprivation. In terms of the first area, there are a few occupations, predominately ones that require sustained attention and focus (e.g., air traffic controllers, surgeons, train drivers, pilots), whereby more safeguarding and monitoring is usually required during the early part of CBT-I. For the exceptions noted above, it may be necessary to take these individuals out of work for the first week or two of CBT-I until they begin to experience better sleep and less daytime sleepiness. However, for most other individuals, it should be noted that a recent study suggests sleep restriction therapy does not confer “risk of significant impairments in sleepiness and reaction times” following 1 and 2 weeks of treatment (Whittall et al., 2018). Therefore, it may be reasonable to simply monitor sleepiness by using a sleepiness scale, such as the Epworth Sleepiness Scale (ESS; Johns, 1991), to track levels of sleepiness at the initiation of treatment and at regular intervals. If the individual reports a high level of daytime sleepiness (i.e., a score of 10 or above on the ESS), then additional support and safeguarding is advised. For example, typically when titrating sleep back into the individual’s schedule, when the criterion of 90% SE is reached, 15 minutes of time in bed is added to the schedule. However, it may be that with significant sleepiness (e.g., ESS > 10), an increase in time allowed in bed of 30 minutes would be more judicious. When the ESS is reduced below 10, then return to a weekly titration of 15 minutes. Other than occupational issues, a useful algorithm for determining who is and who is not a candidate for CBT-I was advanced by Smith and Perlis (2006). Following confirmation that the problem is one of falling asleep or staying asleep (in this case using a 30-minute SL or WASO minimum criteria) with an accompanying daytime complaint, the next stage is to ensure that the sleep problem is not a circadian rhythm issue. Here, the question, “If you were allowed to sleep ad libitum, would the 30 or more minutes awake at night still occur?” is used. If the issue would be resolved by being able to sleep whenever the individual wanted, then the likelihood is that the problem is a delay or advance in the circadian rhythm, and CBT-I is not indicated. The next sections of the algorithm focus on comorbidities. First, it asks (a) whether there are there any undiagnosed or untreated illnesses that will
306 Ellis, Perlis, and Posner
need assessing and treating before treatment is initiated; (b) if the insomnia still remains following appropriate management, then whether the illness prevents the individual engaging with CBT-I; and (c) whether CBT-I would make the illness worse (both exit points). Finally, the algorithm asks whether the individual presents with signs of sleep-incompatible maladaptive behaviors (i.e., excessive time in bed) and/or conditioned hyperarousal. That said, and as we will see shortly, as long as the illness appears to be stable, CBT-I can and has been used in the context of virtually all types of illness.
EFFICACY Before discussing relative efficacy and effectiveness of CBT-I, it is worth noting the outcome measures used within the context of CBT-I. In addition to the data from sleep diaries (in terms of improvements in SL, WASO, and SE), the ISI (Morin, 1993) is commonly used. The ISI is a brief (seven item), valid, and reliable self-report scale that maps onto the main symptom profile of insomnia disorder (Bastien et al., 2001). Although some have used other outcome measures (e.g., Pittsburgh Sleep Quality Index [Buysse et al., 1989]; PROMIS [Buysse et al., 2010]), the ISI remains the most often used outcome measure. One reason for its continued, and likely future, endurance is recent research by Morin and others (Morin et al., 2011), which provides cutoff scores for insomnia in both clinical and community samples (≥ 11 and ≥ 10 respectively) in addition to the point reduction on the ISI, following CBT-I, that equate to a slight improvement (i.e., a reduction of 4.7 points), a moderate improvement (i.e., a reduction of 8.4 points), and a marked improvement (i.e., a reduction of 9.9 points). Beyond the AASM practice parameters, there are now at least 20 metaanalyses that demonstrate that CBT-I is effective and durable (see Table 9.4). As can be seen, these meta-analyses do not just cover insomnia disorder/primary insomnia, but they are also relevant to comorbid insomnia in a wide range of different populations, including several meta-analyses of older adults. The combined evidence suggests moderate to large effects (using the vernacular of Cohen) for CBT-I in terms of reductions in individual symptoms (SL, WASO, SE) and overall insomnia symptomology (e.g., ISI) as well as increases in perceived sleep quality. Moreover, CBT-I appears to be durable, with many of the studies demonstrating only minimal declines in efficacy and/or relapse 1-year postintervention, with one study demonstrating its durability 24 months posttherapy (Morin, Colecchi, et al., 1999). To date, there are only two meta-analyses that compare CBT-I to pharmacotherapy (Mitchell et al., 2012; Smith et al., 2002). The findings of both meta-analyses indicate broadly similar effects for both treatment modalities during acute treatment but reduced efficacy following the discontinuation of pharmacotherapy. Comparisons of long-term durability were difficult, as there have been very few longitudinal studies of the efficacy and effectiveness of pharmacotherapy within the context of insomnia.

Insomnia (> 55 vs. 300 min/week) maintained the largest weight losses at 24 months (~10.5% of initial weight), compared with individuals who engaged in 250–299 min/week (~7% loss), 150–249 min/week (~5.5% loss), and < 150 min/week (~3% loss; Jakicic et al., 2008). For this reason, physical activity goals are often increased to 225–300 min/week during the maintenance phase of lifestyle modification programs (Donnelly et al., 2009). Unfortunately, studies that have randomly assigned participants to high, moderate, or low physical activity recommendations have not found a consistent benefit for high activity prescriptions, likely due to poor adherence to the prescribed activity goals (Catenacci & Wyatt, 2007; Jakicic et al., 2008). Behavior Therapy Adherence to diet and physical activity goals is facilitated through techniques derived from behavior therapy. These techniques are given a more central role in behavioral treatments but are also incorporated into some CBT modules (e.g., barriers to weight loss) alongside cognitive techniques. Core components of behavior therapy include goal setting, self-monitoring, stimulus control, and problem solving.
Cognitive and Behavioral Treatments for Obesity 461
Goal Setting Participants are encouraged to set specific, measurable goals at each session, including targets for modifying diet and physical activity and for changing their environment and habits to facilitate adherence to diet and activity goals (e.g., removing high-calorie foods from home, bringing gym bag to work). Participants are taught both to identify the specific behavior that they wish to adopt and to specify when, where, how, and with whom they will engage in that behavior (Wadden, Crerand, & Brock, 2005). Progress with meeting identified goals is reviewed with the interventionist at the subsequent treatment session and is often shared with other participants during group treatment sessions to further increase accountability. If a goal has not been met, the interventionist (and group, where appropriate) can help the participant to address barriers by problem solving or to modify the goal to make it more likely to be achieved. Self-Monitoring The monitoring of key behaviors allows patients to determine whether their goals are being met and to assess the effect of these changes on body weight. Throughout treatment, participants are encouraged to keep daily records of their food intake and physical activity, and to record their weight at least once weekly. Typically, food records include the types, amounts, and caloric content of all foods and beverages consumed. Ongoing record-keeping throughout the day can help patients select foods for remaining meals to stay within their daily calorie goal. Activity records can include the type and duration of physical activity or pedometer step counts, if available. A number of applications (“apps”) and devices now exist to facilitate the monitoring of food intake and physical activity (Ainsworth et al., 2015; Pagoto et al., 2013). Self-monitoring records typically form the basis for reviewing the patient’s goal progress in treatment. This review can help the patient and interventionist to identify intervention targets (e.g., high-calorie foods that could be replaced or consumed in smaller portions) and behavioral patterns that impact eating and activity (Wadden & Foster, 2000). For example, patients might track additional information about their emotional state or the location of eating episodes to help them to identify cues associated with overeating. The interventionist can also help patients identify additional sources of caloric intake. Most individuals underestimate their calorie intake, and this problem may be most extreme for the minority of patients who report that they are meeting their calorie goals but have not lost weight (Lichtman et al., 1992). All participants are encouraged to weigh or measure foods, when possible, to improve recording accuracy. A high frequency of self-monitoring is associated with better long-term weight loss (e.g., Tronieri et al., 2020; Wadden, Berkowitz, et al., 2005), and frequency of monitoring itself is often discussed as a behavioral goal in treatment. Barriers to record-keeping can be addressed by problem solving, or the interventionist may prescribe a more flexible monitoring schedule, as appropriate.

Stimulus Control As discussed previously, both internal (e.g., emotions) and external (e.g., sight or smell of food) cues can become associated with eating or (in)activity. Stimulus control seeks to modify or reduce exposure to problematic cues, and to increase cues for behavioral targets in order to facilitate adherence to diet and activity goals (Butryn et al., 2011; Wadden, Crerand, & Brock, 2005). For example, patients can be taught to modify their environment by avoiding storing large quantities of high-calorie foods in their home and by increasing the visibility of healthy, low-calorie options (such as by storing them at eye-level). Problem Solving Behavior analysis involves the examination of antecedents (i.e., precipitating factors), behaviors, and consequences (i.e., reinforcement value) as a means of understanding factors that may contribute to a given behavior pattern (Wadden, Crerand, & Brock, 2005). Participants are taught to identify the series of preceding factors that may have contributed to an episode of overeating or physical inactivity, including both situational factors and cognitive and emotional antecedents. Linking these events and their consequences to form a “behavior chain” (see Figure 14.1) can allow the participant to identify opportunities to “break the chain” in the future by intervening to alter the sequence of events (Brownell, 2004; Wadden, Crerand, & Brock, 2005). Participants are taught to brainstorm possible solutions, select the intervention with the greatest likelihood of success (early in the chain, if possible), and implement and evaluate the solution’s efficacy. For example, in Figure 14.1, the patient might prevent overeating by using assertiveness skills (e.g., talking to friend about health goals, suggesting an alternative activity), stimulus control (e.g., selecting a restaurant that promotes healthy options, eating a healthy snack to reduce hunger), cognitive restructuring (e.g., “My health goals are important even though I’ve had a hard day. I can treat myself to a relaxing activity instead of with food”), or skills to cope with negative emotions (e.g., listening to music or talking to a friend to reduce stress). Cognitive Behavioral Therapy As in many CBTs, cognitive restructuring is used in obesity treatments to identify, test, and correct distorted or irrational thoughts that may interfere with behavior change. In behavioral treatment, unhelpful thoughts in response to lapses (i.e., deviations from eating/activity plan) are a primary target for cognitive restructuring (Wadden & Foster, 2000; Wadden et al., 2003). Patients may respond to overeating episodes by either minimizing (e.g., “Eating a few more won’t matter”) or magnifying their impact (e.g., “I’ve already blown it; I might as well eat whatever I want”). Either pattern can delay or prevent attempts to respond to the lapse by resuming efforts to meet diet and activity goals. Patients are taught to identify and respond to unrealistic thoughts by characterizing the lapse as a temporary setback that they can learn from, and emphasizing the importance of getting back on track as soon as possible.

FIGURE 14.1. A Behavior Chain
Note. Situations, feelings, and thoughts that lead to or result from a given behavior (i.e., antecedents and consequences) are linked to help a patient to identify opportunities for intervention. Additional behavior chain examples can be found in Brownell (2004).
As described previously, the primary target for cognitive change in CBT for obesity is to help patients correct unrealistic expectations about weight loss and to view weight maintenance as a distinct and worthwhile goal that requires active intervention (Cooper & Fairburn, 2001). According to the theory underlying the treatment, patients who have more realistic expectations for weight loss and maintenance from the outset of treatment will be less likely to become discouraged when weight loss slows, more likely to appreciate the benefits of the loss that has been achieved, and, therefore, more likely to engage in the behaviors necessary to maintain lost weight. Through guided argument, the therapist helps the patient recognize the arbitrariness of their weight goal and that weight loss of a large magnitude is likely to be unrealistic (based on the patient’s prior experience) because it requires the maintenance of dietary restriction for long periods (Cooper & Fairburn, 2002). Through this discussion, the therapist and patient form a model for how unrealistic weight goals have impacted the patient’s ability to maintain lost weight with past attempts. During the weight loss maintenance phase, patients are explicitly discouraged from seeking further weight loss and are taught strategies associated with long-term weight maintenance (e.g., monitoring weight, cognitive responses, physical activity, flexible healthy eating; Cooper & Fairburn, 2001). A related goal in CBT for obesity is to help patients correct beliefs about the degree to which their “primary goals” (i.e., the goals that the patient hopes to achieve through weight loss) are tied to losing weight. Some goals may be reached with less weight loss than anticipated (e.g., health or fitness goals), whereas others can be addressed independently of weight loss (e.g., relationship goals, improving self-esteem; Cooper & Fairburn, 2001). Treatment seeks
464 Jena Shaw Tronieri
to help patients to both recognize the benefits of the weight loss that they have achieved and to separate the pursuit of primary goals from their weight loss goals (Cooper & Fairburn, 2002). For example, the body image module helps patients to improve body image directly by testing assumptions that maintain excessive body checking and/or avoidance, correcting negative thoughts about body shape, and encouraging body acceptance (Cooper & Fairburn, 2002). Problem-solving strategies are incorporated to help patients to take steps toward achieving other primary goals.
OUTCOME DATA After 6–12 months of treatment, intensive lifestyle modification programs produce mean losses of 5%–10% of initial weight (approximately 5–10 kg) that are significantly larger than those produced by usual care (e.g., advice, psychoeducation; Jensen et al., 2014; Wadden et al., 2020). Moderate-intensity programs (i.e., 1–2 sessions per month) are associated with smaller mean losses (Jensen et al., 2014). Christian et al. (2010) combined categorical data from 14 studies to show that a substantial portion of participants achieve clinically meaningful weight loss after 12 months, particularly in intensive programs (see Figure 14.2). Sustained losses of as little as 3%–5% can produce clinically meaningful health benefits, including improvements in triglycerides, blood glucose, hemoglobin A1c, and the risk of developing Type 2 diabetes (Jensen et al., 2014). Losses greater than 5% are associated with improvements in blood pressure, high- and low-density lipoprotein cholesterol, and lipids (Jensen et FIGURE 14.2. Percent of Participants Who Achieve Categorical Weight Loss
Note. Outcomes at 1 year in intensive and less-intensive behavioral treatment programs, as reviewed in Christian et al., 2010. Not enough intensive programs reported the percent of participants who achieved a 0.1-4.9% loss or no weight loss to allow those results to be included.

al., 2014), as well as quality of life and depression (Wing & Hill, 2001). Across these health outcomes, larger losses are associated with greater improvements (Wing et al., 2011). Weight regain continues to temper the long-term benefits of lifestyle modification. On average, one third of lost weight is regained in the year following treatment, and nearly half of participants have returned to their starting weight at 5 years posttreatment (Butryn et al., 2011). However, 35%–60% of patients maintain losses greater than 5% at 2 or more years after treatment, and weight losses remain superior to usual care at long-term follow-up points (Jensen et al., 2014). Further, although many of the benefits to cardiometabolic risk factors are reversed or diminished by weight regain, some may outlast the initial weight loss. For example, in the DPP, the intensive lifestyle modification program produced a 5.6 kg weight loss after a mean of 2.8 years that was associated with a 58% lower incidence in the development of Type 2 diabetes, compared with placebo (Knowler et al., 2002). At 10 years posttreatment, weight loss no longer differed between the groups (–2 kg for lifestyle intervention and –1 kg for placebo), but the lifestyle intervention group maintained a 34% lower incidence of Type 2 diabetes (Knowler et al., 2009). On an individual basis, successful weight loss maintenance is associated with ongoing engagement in key weight-control behaviors, including the consumption of a low-calorie diet, high levels of physical activity, and regular monitoring of body weight (Klem et al., 1997; Wadden et al., 2011; Wing & Hill, 2001). Successful weight-loss maintainers report a lower caloric intake than individuals who have a similar current weight with no history of weight reduction (e.g., Shick et al., 1998). This difference may be attributable to metabolic adaptation that is disproportionate to the change in their body mass (e.g., Astrup et al., 1999; Fothergill et al., 2016); however, not all studies have identified such deficits (e.g., Wadden et al., 1990), and others suggest that there is high individual variability in the degree of metabolic adaptation (Fothergill et al., 2016; van Dale et al., 1990). High levels of physical activity may help patients overcome changes in resting metabolic rate that would otherwise produce weight regain (van Dale et al., 1990). Regular self-weighing may facilitate maintenance because it allows patients to detect small increases in weight and implement additional weight control strategies to prevent further regain from occurring (Butryn et al., 2007). Additional behaviors, such as eating regularly throughout the day (an average of 4.9 meals and snacks/day), eating breakfast on most days, limiting eating out, eating a low-fat diet, and limiting television watching, are also reported by successful weight maintainers (Klem et al., 1997) and likely support their consumption of a low-calorie diet and high activity levels. Two treatment approaches have been shown to improve the maintenance of lost weight, likely by facilitating adherence to behaviors associated with long-term weight control. The first is the provision of ongoing lifestyle modification sessions, which reduce weight regain for periods of up to 2.5 years after initial weight loss (Jensen et al., 2014; Perri & Corsica, 2002). In a review of 13 studies assessing the benefit of ongoing sessions for weight-loss maintenance
466 Jena Shaw Tronieri
(Perri & Corsica, 2002), extended treatment (for an average of 12.5 months) resulted in the maintenance of 96.3% of the initial mean 10.7 kg loss (equivalent to 10.3 kg). Comparison conditions with no extended contact maintained a lower 66.5% (6.6 kg) of the initial loss. In longer-term treatment (beyond 1 year), treatment attendance begins to decline and some regain occurs, resulting in an average maintenance of 65.8% at 22 months for patients who are provided with ongoing treatment, compared with 38.3% for those who are not (Perri & Corsica, 2002). The rate of weight regain appears to level off, such that patients still maintain about 50% of their initial weight loss after 3 or more years of extended treatment (Knowler et al., 2002; Wadden et al., 2014). The second treatment approach is the addition of medications approved by the U.S. Food and Drug Administration (FDA) for weight management. This approach has been likened to the treatment of other chronic health conditions that require long-term pharmacologic intervention (Butryn et al., 2011). Several trials have shown that the addition of obesity medication after weight loss induction aids in the maintenance of lost weight (Hill et al., 1999; Smith et al., 2010; Wadden et al., 2013). However, the benefit of some pharmacologic agents may be small when combined with ongoing weight loss maintenance counseling (Tronieri et al., 2018), and more research is needed to evaluate the long-term benefit of recent FDA-approved medications. The Effect of Treatment Components on Weight Loss In addition to treatment intensity and duration, treatment format may influence short- and long-term weight loss. Group treatment has been shown to produce larger weight losses than individually delivered treatment in some studies (e.g., Renjilian et al., 2001), but equivalent losses in others (e.g., Minniti et al., 2007). Small group size appears to produce superior losses compared with large groups (e.g., 12 participants vs. 30 participants; Dutton et al., 2014). The results of a Cochrane review found that the combination of behavior therapy, diet, and physical activity (i.e., behavioral treatment) produces larger weight losses than treatment with diet and activity recommendations alone (Shaw et al., 2005). Behavioral treatment is typically delivered as a package, and the degree to which most individual behavior therapy components improve weight loss has not been tested in an RCT. Of these strategies, more frequent self-monitoring of dietary intake and weight has been associated with greater weight loss in several studies (e.g., Butryn et al., 2011; Tronieri et al., 2020; Wadden, Berkowitz, et al., 2005). A number of studies have tested whether treatment packages that add or emphasize particular skills produce superior results compared with standard behavioral treatment. The addition of a self-efficacy intervention (Burke et al., 2015), problem-solving therapy (Perri et al., 2001), or acceptance-based strategies (Forman et al., 2016) may improve weight loss, but further study is needed to replicate these results. Interventions that have not significantly improved weight-loss outcomes include increased attention to modifying the home envi-
Cognitive and Behavioral Treatments for Obesity 467
ronment, motivation-focused treatments (that highlight benefits associated with different motivations for weight loss), and relapse prevention training (although training in weight stability maintenance prior to initiating weight loss may be beneficial; Perri & Ariel-Donges, 2018). Of note, CBT for obesity as described by Cooper and Fairburn was not found to produce weight losses superior to behavioral treatment in an RCT (Cooper et al., 2010). After 44 weeks, behavioral treatment produced a mean loss of 12.7% of initial weight, compared with 8.9% with CBT (and 5.4% with guided self-help; differences between the behavioral and CBT groups were not statistically significant p = .07). During the 3-year follow-up, rate of weight regain did not differ between the two intervention groups, such that behavioral treatment had total losses that were still 2.8 kg larger than CBT participants at the end of the follow-up period. CBT produced greater improvements in body shape acceptance than behavioral treatment, but the hypothesis that those improvements would facilitate weight loss maintenance was not supported (Cooper et al., 2010). Efficacy of Lifestyle Modification With Diverse Populations A number of studies have examined whether demographic characteristics or comorbid conditions predict weight loss with lifestyle modification. In most studies, sex, education, employment, and marital status are not associated with weight loss (Fabricatore et al., 2009; Gomez-Rubalcava et al., 2018). Some studies have found younger age to predict poorer weight loss (Delahanty et al., 2013; Gokee-LaRose, Gorin, Raynor, et al., 2009; Wadden et al., 2011), whereas others have not (Fabricatore et al., 2009; Gomez-Rubalcava et al., 2018). It may be that younger individuals are more likely to have competing demands on their time (e.g., childcare, early career status) that interfere with their ability to focus on weight-loss goals. One study found that young adults aged 21–35 years attended fewer sessions (52% vs. 74%) and were less likely to complete 6 months of treatment than older adults (Gokee-LaRose, Gorin, Raynor, et al., 2009). Modifying treatment by limiting enrollment to young adults and directly addressing behaviors and experiences that are relevant to that age group may improve their treatment outcomes (Gokee-LaRose, Gorin, & Wing, 2009). Similarly, some studies have found that racial/ethnic minorities, particularly Black women, lose less weight in behavioral programs than their White counterparts after 6–12 months (Delahanty et al., 2013; Fabricatore et al., 2009; Gomez-Rubalcava et al., 2018). However, the smaller losses of Black participants may be better maintained than the larger losses of the White participants, and several studies suggest that longer-term losses do not differ by race/ethnicity (Gomez-Rubalcava et al., 2018; Seo & Sa, 2008; Wadden, et al., 2011). Researchers have suggested that lifestyle modification programs should be tailored to address sociocultural and environmental factors relevant to minority groups. However, interventions adapted for Black participants have reported only modest initial mean weight losses, and treatment delivery by interventionists
468 Jena Shaw Tronieri
of the same race/ethnicity does not improve weight loss (Seo & Sa, 2008). In meta-analysis, individually delivered interventions and interventions that included a family component were associated with larger weight losses in minority groups (Seo & Sa, 2008), but studies that directly compare interventions with these components to standard behavioral treatment are needed. Obesity is associated with a higher prevalence of psychological problems, including binge-eating disorder, depressive disorders, and anxiety disorders (Puhl & Pearl, 2018). The presence of these comorbid conditions has been hypothesized to limit weight loss; however, most studies have not found baseline binge eating, depression, or anxiety to predict treatment outcome (Fabricatore et al., 2009; Gomez-Rubalcava et al., 2018; Tronieri & Wadden, 2018). Patients who continue to experience binge eating during treatment may lose less weight (Chao et al., 2017; Grilo et al., 2011). A study by Grilo et al. (2011) compared CBT for binge-eating disorder to behavioral weight-loss treatment and combined treatment (CBT followed by behavioral weight loss) for producing binge-eating remission and weight loss. The three groups had similar rates of binge-eating remission after 24 weeks of treatment (44%, 38%, and 49%, respectively) and at a 12-month follow-up (51%, 36%, and 40%, respectively). However, reductions in binge frequency, while similar at posttreatment, were better maintained at 12-month follow-up in CBT than in BWL. At posttreatment, weight loss was greater in the behavioral and combined groups when compared with CBT; however, these differences were not maintained at follow-up. Similarly, depressive symptoms tend to improve in behavioral weight-loss treatment, although these improvements may decline over long-term follow-up in association with weight regain (Tronieri & Wadden, 2018). Treatments that combine behavioral weight loss and CBT for depression may lead to greater improvements in mood than behavioral treatment alone, but do not improve weight-loss outcomes. In general, these findings suggest that the presence of comorbid psychological conditions is not a contraindication to weight loss treatment for most patients; however, it is best practice to provide appropriate mental health referrals for the treatment of the psychological symptoms (Tronieri & Wadden, 2018).
DISSEMINATION Research on the efficacy of lifestyle modification for obesity has typically been conducted in academic medical settings (e.g., DPP Research Group, 2002; Wadden et al., 2006). Such programs are not widely available and can involve substantial costs, both to the institution and to participants who incur costs to travel to the site, even if treatment is provided free of charge. Participants typically are screened for appropriateness, which may involve the exclusion of individuals with certain medical or psychological conditions. They typically attend several visits prior to beginning treatment and thus are likely to be more
Cognitive and Behavioral Treatments for Obesity 469
highly motivated than individuals who do not complete the screening process or who do not volunteer for long-term research studies. Further, the behaviors required for successful weight loss represent a substantial commitment of time and effort on the part of the participant, as does their long-term attendance of treatment sessions. Providing lifestyle modification programs in community, primary care, and workplace settings can improve patient access. Of these, studies of behavioral treatments delivered in community centers produce outcomes that are most similar to those conducted in academic medical centers and are associated with lower program and participant costs (Butryn et al., 2011). Most studies also have found that high-intensity lifestyle modification programs (that provide at least 12 sessions per year, as defined by the U.S. Preventative Services Task Force) produce clinically meaningful weight losses (4–7 kg) when delivered in person or by phone in primary care settings (Tronieri et al., 2019). However, intensive programs are difficult to integrate into clinical practices due to lack of provider time, training, and reimbursement. Low- to moderate-intensity counseling delivered in primary care may be somewhat more feasible but produces only modest weight losses of 1–2 kg. Worksite programs also typically produce small mean losses (e.g., 1–2 kg; Butryn et al., 2011). Delivering lifestyle interventions by telephone, internet, or smartphone app may also improve their accessibility and reduce cost and time burdens. Telephone delivery has been shown to be as effective as in-person delivery for both weight loss and weight maintenance and substantially reduces travel costs to the participant (but not clinic costs; Donnelly et al., 2013; Perri & Ariel-Donges, 2018). Internet- and app-based treatments may have the widest availability and lowest costs. For weight loss, internet-based treatment consistently produces smaller losses than in-person treatment but is superior to minimal treatment in some studies (Butryn et al., 2011; Sherrington et al., 2016). Online treatments that offer a structured program of diet, physical activity, and behavioral strategies (Butryn et al., 2011), and that provide interventionist feedback, produce the strongest results (a mean 2.1 kg loss in meta-analysis; Sherrington et al., 2016). Internet-based programs may be more effective for facilitating weight-loss maintenance, and two studies found no differences between online and in-person delivery methods (Butryn et al., 2011). However, two other studies found that online programs resulted in greater weight regain than in-person treatment (1.2 and 4.7 kg more, respectively; Harvey-Berino et al., 2002; Svetkey et al., 2008). As noted previously, smartphone apps are now frequently used by individuals who are enrolled in behavioral treatment to facilitate self-monitoring of eating, weight, and physical activity. These apps could also be used to provide stand-alone interventions. A recent systematic review found that 13 of 21 studies (62%) did not find that apps produce greater weight loss than a control condition (Covolo et al., 2017). However, this is a relatively recent area of research and many studies were of low quality. Additionally, research-based apps may be less user-friendly than commercially available apps, which may

impact their use. On the other hand, most of the numerous commercial apps that claim to facilitate weight loss, healthy eating, calorie tracking, or physical activity have not been tested in an RCT. A review of 30 commercial apps for weight loss found that, on average, they included only 19% of the behavioral strategies used in a typical lifestyle modification program (Pagoto et al., 2013). It is likely that the average benefit of such apps is small, if present. However, because of their wide reach and low cost, it is worthwhile to continue to investigate whether their efficacy can be improved by developing apps that are both easy to use and incorporate evidence-based techniques and corrective feedback.
CONCLUSION A distinction has been drawn between behavioral and cognitive behavioral obesity treatments based on the theoretical primacy of behavioral versus cognitive change, respectively, for producing weight loss and long-term weight maintenance. However, in practice, these treatments share many core features, including prescriptions for dietary change and increased physical activity and the use of behavioral and cognitive strategies to facilitate adherence to those recommendations. Further, when compared in an RCT, the two treatments did not produce different amounts of initial weight loss or different rates of weight regain. Instead, lifestyle modification programs with either a cognitive or behavioral emphasis can be expected to produce mean losses of 5%–10% of initial body weight and related improvements in cardiometabolic and psychosocial outcomes. Weight regain after treatment continues to be common and is reduced, on average, by the provision of ongoing behavioral or pharmacologic treatment. Patients who continue to consume a low-calorie diet and engage in high levels of physical activity are most likely to maintain lost weight in the long term. Further research is needed to develop methods for increasing access to these interventions and reducing treatment burden without significantly diminishing the treatments’ efficacy.
