Background The effectiveness of psychotherapeutic interventions for eating disorders (EDs) is widely studied in Europe, North America, and Australia/New Zealand. However, few controlled studies and no randomized controlled trials (RCTs) have been conducted in Japan despite the relatively high prevalence of EDs in the Japanese population. The aim of this study is to evaluate the effect of enhanced cognitive behavior therapy (CBT-E), an evidence-supported ED-focused form of cognitive behavior therapy (CBT), for the treatment of bulimia nervosa (BN) in Japan. Methods/design This multicenter RCT will compare CBT-E with treatment as usual (TAU), which is widely used in Japan. A group of 140 adult outpatients with a Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) diagnosis of BN, ≥18 years of age, a body mass index (BMI) > 17.5 and 2 will be randomly assigned to CBT-E or TAU. Participants will be stratified by intervention site and BN severity. CBT-E participants will receive 20 sessions of focused form CBT-E for 20 weeks. Those in the TAU group will receive routine treatment provided by specialists. Assessment will be performed in a blinded manner prior to the start of treatment, after 6 weeks of treatment, at the end of treatment (20 weeks), and at follow-up at 40 and 80 weeks after the start of treatment. The primary outcome is the remission of BN, defined by the absence, in the previous 4 weeks, of symptoms required to meet the DSM-5 criteria for a diagnosis of BN. Secondary outcomes include the levels of ED psychopathology and impairment due to the ED, anxiety, depression, family function, and satisfaction with treatment. Discussion This will be the first RCT conducted in Japan to compare CBT-E and TAU for the treatment of BN. If CBT-E is found to be more effective than TAU, then the evidence would support its wider use for patients with BN in Japan. Because it is possible to train therapists who do not possess extensive specialist experience, wider use is also likely to be practically feasible. In addition, demonstrating the effectiveness of CBT-E in Japan would demonstrate that it could be successfully extended to additional world cultures and regions.

Background Cognitive–behavioural therapy aims to increase quality of life by changing cognitive and behavioural factors that maintain problematic symptoms. A previous overview of cognitive–behavioural therapy systematic reviews suggested that cognitive–behavioural therapy was effective for many conditions. However, few of the included reviews synthesised randomised controlled trials. Objectives This project was undertaken to map the quality and gaps in the cognitive–behavioural therapy systematic review of randomised controlled trial evidence base. Panoramic meta-analyses were also conducted to identify any across-condition general effects of cognitive–behavioural therapy. Data sources The overview was designed with cognitive–behavioural therapy patients, clinicians and researchers. The Cochrane Library, MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Child Development & Adolescent Studies, Database of Abstracts of Reviews of Effects and OpenGrey databases were searched from 1992 to January 2019. Review methods Study inclusion criteria were as follows: (1) fulfil the Centre for Reviews and Dissemination criteria; (2) intervention reported as cognitive–behavioural therapy or including one cognitive and one behavioural element; (3) include a synthesis of cognitive–behavioural therapy trials; (4) include either health-related quality of life, depression, anxiety or pain outcome; and (5) available in English. Review quality was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2. Reviews were quality assessed and data were extracted in duplicate by two independent researchers, and then mapped according to condition, population, context and quality. The effects from high-quality reviews were pooled within condition groups, using a random-effect panoramic meta-analysis. If the across-condition heterogeneity was I 2 Results A total of 494 reviews were mapped, representing 68% (27/40) of the categories of the International Classification of Diseases, Eleventh Revision, Mortality and Morbidity Statistics. Most reviews (71%, 351/494) were of lower quality. Research on older adults, using cognitive–behavioural therapy preventatively, ethnic minorities and people living outside Europe, North America or Australasia was limited. Out of 494 reviews, 71 were included in the primary panoramic meta-analyses. A modest effect was found in favour of cognitive–behavioural therapy for health-related quality of life (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval –0.05 to 0.50, I 2 = 32%), anxiety (standardised mean difference 0.30, 95% confidence interval 0.18 to 0.43, prediction interval –0.28 to 0.88, I 2 = 62%) and pain (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval –0.28 to 0.74, I 2 = 64%) outcomes. All condition, subgroup and sensitivity effect estimates remained consistent with the general effect. A statistically significant interaction effect was evident between the active and non-active comparator groups for the health-related quality-of-life outcome. A general effect for depression outcomes was not produced as a result of considerable heterogeneity across reviews and conditions. Limitations Data extraction and analysis were conducted at the review level, rather than returning to the individual trial data. This meant that the risk of bias of the individual trials could not be accounted for, but only the quality of the systematic reviews that synthesised them. Conclusion Owing to the consistency and homogeneity of the highest-quality evidence, it is proposed that cognitive–behavioural therapy can produce a modest general, across-condition benefit in health-related quality-of-life, anxiety and pain outcomes. Future work Future research should focus on how the modest effect sizes seen with cognitive–behavioural therapy can be increased, for example identifying alternative delivery formats to increase adherence and reduce dropout, and pursuing novel methods to assess intervention fidelity and quality.

Increased interest in disseminating and implementing psychological treatments has focused on the need for evidence-based training programs for providers, especially those without specialized training. To evaluate provider-training programs, validated outcome measures are necessary; however, the scalable measurement of training outcomes has been largely overlooked. Current methods of assessing providers' ability to deliver psychological treatments are generally time-consuming and costly, representing a major bottleneck in scaling up mental health care for commonly occurring disorders such as depression. The present study describes the development and initial validation of a scalable measure for assessing provider competence in delivering a brief behavioral activation treatment for depression, called the Healthy Activity Program, adapted for primary care settings. The measure focuses on testing knowledge about the treatment and applied knowledge regarding how to skillfully deliver the treatment, both essential features of competence. The measure was tested on a sample of 531 respondents with a variety of educational levels and professional backgrounds and found to meet the requirements of the Rasch model. Three versions of the measure each of equal difficulty were derived to allow repeat testing of training outcomes over time. A scalable measure of provider competence is an essential first step towards supporting the wider dissemination and implementation of brief psychological interventions for depression, especially in low-resource settings.

Objective: Understanding the mechanisms of action of psychological treatments is a key first step in refining and developing more effective treatments. The present study examined hypothesized mediators of change of enhanced cognitive behavior therapy (CBT‐E) and interpersonal psychotherapy for eating disorders (IPT‐ED).Method: A series of mediation studies were embedded in a randomized controlled trial (RCT) comparing 20 weeks of CBT‐E and IPT‐ED in a transdiagnostic, non‐underweight sample of patients with eating disorders (N = 130) consecutively referred to the service. Three hypothesized mediators of change in CBT‐E (regular eating, weighing frequency, and shape checking) and the key hypothesized mediator of IPT‐ED (interpersonal problem severity) were studied.Results: The data supported regular eating as being a mediator of the effect of CBT‐E on binge‐eating frequency. The findings were inconclusive regarding the role of the other putative mediators of the effects of CBT‐E; and were similarly inconclusive for interpersonal problem severity as a mediator of the effect of IPT‐ED.Discussion: This research highlights the potential benefits of embedding mediation studies within RCTs to better understand how treatments work. The findings supported the role of regular eating in reducing patients' binge‐eating frequency. Other key hypothesized mediators of CBT‐E and IPT‐ED were not supported, although the data were not inconsistent with them. Key methodological issues to address in future work include the need to capture both behavioral and cognitive processes of change in CBT‐E, and identifying key time points for change in IPT‐ED.

In the past few weeks, coronavirus disease 2019 (COVID-19) has dramatically expanded across the world. To limit the spread of COVID-19 and its negative consequences, many countries have applied strict social distancing rules. In this dramatic situation, people with eating disorders are at risk of their disorder becoming more severe or relapsing. The risk comes from multiple sources including fears of infection and the effects of social isolation, as well as the limited availability of adequate psychological and psychiatric treatments. A potential practical solution to address some of these problems is to deliver enhanced cognitive behaviour therapy (CBT-E), an evidence-based treatment for all eating disorders, remotely. In this guidance we address three main topics. First, we suggest that CBT-E is suitable for remote delivery and we consider the challenges and advantages of delivering it in this way. Second, we discuss new problems that patients with eating disorders may face in this period. We also highlight potential opportunities for adapting some aspects of CBT-E to address them. Finally, we provide guidelines about how to adapt the various stages, strategies and procedures of CBT-E for teletherapy use in the particular circumstances of COVID-19. Key learning aims (1) To appreciate that CBT-E is suitable for remote delivery, and to consider the main challenges and potential advantages of this way of working. (2) To identify and discuss the additional eating disorder-related problems that may arise as a result of COVID-19, as well as potential opportunities for adapting some aspects of CBT-E to address them. (3) To learn how to adapt CBT-E for remote delivery to address the consequences of COVID-19. Specifically, to consider adaptations to the assessment and preparation phase, the four stages of treatment and its use with underweight patients and adolescents.

Anorexia nervosa is difficult to treat and no treatment is supported by robust evidence. As it is uncommon, it has been recommended that new treatments should undergo extensive preliminary testing before being evaluated in randomized controlled trials. The aim of the present study was to establish the immediate and longer-term outcome following “enhanced” cognitive behaviour therapy (CBT-E). Ninety-nine adult patients with marked anorexia nervosa (body mass index ≤ 17.5) were recruited from consecutive referrals to clinics in the UK and Italy. Each was offered 40 sessions of CBT-E over 40 weeks with no concurrent treatment. Sixty-four percent of the patients were able to complete this outpatient treatment and in these patients there was a substantial increase in weight (7.47 kg, SD 4.93) and BMI (2.77, SD 1.81). Eating disorder features also improved markedly. Over the 60-week follow-up period there was little deterioration despite minimal additional treatment. These findings provide strong preliminary support for this use of CBT-E and justify its further evaluation in randomized controlled trials. As CBT-E has already been established as a treatment for bulimia nervosa and eating disorder not otherwise specified, the findings also confirm that CBT-E is transdiagnostic in its scope., Highlights ► CBT-E is designed to address eating disorder psychopathology. ► The findings show that CBT-E can be used with patients with marked anorexia nervosa. ► Two-thirds of the patients completed treatment. ► Among the completers there was a substantial, and well maintained, response. ► The findings confirm that CBT-E is transdiagnostic in its scope.

Large numbers of therapists worldwide wish to receive training in how to deliver psychological treatments. Current methods of training are poorly suited to this task as they are costly and require scarce expertise. New forms of training therefore need to be developed that are more cost-effective and scalable. Internet-based methods might fulfil these requirements whilst having the added advantage of being able to provide trainees with extensive exposure to the treatment as practised. New strategies and procedures for evaluating training outcome are also required. These need to be capable of assessing the therapist's knowledge of the treatment and its use, as well as the therapist's ability to apply this knowledge in clinical practice. Standardised role play-based techniques might be of value in this regard. © 2011 Elsevier Ltd.

It is remarkably difficult for people with obesity to maintain a new lower weight following weight loss. The aim of the present study was to examine the immediate and longer-term effects of a new cognitive behavioural treatment that was explicitly designed to minimise this post-treatment weight regain. One hundred and fifty female participants with obesity were randomized to the new treatment, behaviour therapy (the leading alternative psychological treatment) or guided self-help (a minimal intervention). Both of the main treatments resulted in an average weight loss of about ten percent of initial weight whereas weight loss was more modest with guided self-help. The participants were subsequently followed-up for three years post-treatment. The great majority regained almost all the weight that they had lost with the new treatment being no better than the behavioural treatment in preventing weight regain. These findings lend further support to the notion that obesity is resistant to psychological methods of treatment, if anything other than a short-term perspective is taken. It is suggested that it is ethically questionable to claim that psychological treatments for obesity “work” in the absence of data on their longer-term effects.

Background Many risk factors have been implicated in the development of anorexia nervosa. Little is known about their relative contributions, nor in most cases is it clear whether they are specific to anorexia nervosa or risk factors for all eating disorders or for psychiatric disorder in general. Methods We used a case-control design involving the comparison of 67 female subjects with a history of anorexia nervosa with 204 healthy control subjects, 102 subjects with other psychiatric disorders, and 102 subjects with bulimia nervosa. A broad range of risk factors was assessed by interview. Results The subjects with anorexia nervosa and the healthy controls differed in their exposure to most of the putative risk factors. There was no greater exposure to factors that increased the likelihood of dieting, once the influence of other classes of risk factors had been taken into account. Premorbid perfectionism and negative self-evaluation were especially common and more so than among the general psychiatric controls. Parental obesity and an early menarche, together with parental psychiatric disorder, distinguished those with bulimia nervosa from those with anorexia nervosa. Conclusions There appears to be a broad range of risk factors for anorexia nervosa and bulimia nervosa, some of which are shared with other psychiatric disorders. Factors that increase the likelihood of dieting seem to have more important influence as risk factors for bulimia nervosa than anorexia nervosa. Perfectionism and negative self-evaluation appear to be particularly common and characteristic antecedents of both eating disorders.

SummaryThe DSM–IV scheme for classifying eating disorders is a poor reflection of clinical reality. In adults it recognises two conditions, anorexia nervosa and bulimia nervosa, yet these states are merely two presentations among many. As a consequence, at least half the cases seen in clinical practice are relegated to the residual diagnosis ‘eating disorder not otherwise specified’. The changes proposed for DSM–5 will only partially succeed in correcting this shortcoming. With DSM–6 in mind, it is clear that comprehensive transdiagnostic samples need to be studied with data collected on their current state, course and response to treatment. Only with such data will it be possible to derive an empirically based classificatory scheme that is both rooted in clinical reality and of value to clinicians.

Interpersonal psychotherapy (IPT) is a leading evidence-based treatment for those eating disorders in which binge eating is a feature. This article begins with a consideration of the rationale for using IPT to treat patients with eating disorders. This is followed by a review of the evidence supporting its use and a brief description of treatment including an illustrative clinical case vignette. The article closes with a discussion of possible future directions for research on IPT for eating disorders. Copyright © 2012 John Wiley & Sons, Ltd. Key Practitioner Message IPT for eating disorders (IPT-ED) closely resembles IPT for depression and primarily focuses on current interpersonal problems. It is well suited for helping patients to address interpersonal difficulties which appear to be maintaining the eating disorder.

It is a consistent finding that, among obese patients, the weight lost as a result of the most widely available treatments for obesity is almost always regained. This relapse appears to be attributable to the individual's inability to persist with the behavioural strategies needed to maintain the new lower weight. Little research has investigated the psychological mechanisms that might account for this phenomenon. This study aimed to identify psychological factors that predict weight regain. Fifty-four women with obesity who had lost weight by attending community slimming clubs were interviewed immediately after losing 10% of their initial body weight, and then followed-up every 2 months for a period of 1 year by means of telephone interviews. The results identified two prospective predictors of weight regain: one cognitive factor (dichotomous thinking) and one historical variable (maximum lifetime weight). The finding that a specific cognitive style is a significant predictor of relapse has implications for the treatment of obesity.

In recent years there has been widespread acceptance that cognitive behavior therapy (CBT) is the treatment of choice for bulimia nervosa. The cognitive behavioral treatment of bulimia nervosa (CBT-BN) was first described in 1981. Over the past decades the theory and treatment have evolved in response to a variety of challenges. The treatment has been adapted to make it suitable for all forms of eating disorder—thereby making it “transdiagnostic” in its scope— and treatment procedures have been refined to improve outcome. The new version of the treatment, termed enhanced CBT (CBT-E) also addresses psychopathological processes “external” to the eating disorder, which, in certain subgroups of patients, interact with the disorder itself. In this paper we discuss how the development of this broader theory and treatment arose from focusing on those patients who did not respond well to earlier versions of the treatment.

SummaryBinge eating occurs across the entire range of eating disorders. It is required for a diagnosis of bulimia nervosa but it is also seen in some cases of anorexia nervosa and in many cases of eating disorder not otherwise specified (usually referred to as eating disorder NOS or atypical eating disorder). This article focuses on the management of those eating disorders in which binge eating is a prominent feature.

Hetherington has recently argued that psychology's concern with anecdotal evidence, introspective data and rare or one-off events renders the methodology and explanatory model of the natural sciences inappropriate and inadequate; and as such psychology needs to develop its own methods of inquiry. However, an examination of his arguments reveals that psychological data do not require explanation of a radically different kind from that employed in the natural sciences. Hetherington is correct in emphasizing that what is distinctive about the subject matter of psychology is its concern with intentional content; however, the conclusions he draws about the special nature of psychological explanation are unwarranted.

The EDE is a semistructured interview which has been developed as a measure of the specific psychopathology of anorexia nervosa and bulimia nervosa. To establish its discriminant validity it was administered to 100 patients with anorexia nervosa or bulimia nervosa and to 42 controls. The two groups differed significantly on all items. Five subscales were derived on rational grounds and evaluated on the two populations. The α coefficients for each subscale indicated a satisfactory degree of internal consistency. The EDE provides clinicians and research workers with a detailed and comprehensive profile of the psychopathological features of patients with eating disorders.

Purpose. The purpose of this paper is to review the rationale for 'transdiagnostic' approaches to the understanding and treatment of anxiety disorders. Methods. Databases, searches and examination of the reference lists of relevant studies were used to identify papers of relevance. Results. There is increasing recognition that diagnosis-specific interventions for single anxiety-disorders are of less value than might appear since a large proportion of patients have more than one coexisting anxiety disorder and the treatment of one anxiety disorder does not necessarily lead to the resolution of others. As transdiagnostic approaches have the potential to address multiple coexisting anxiety disorders they are potentially more clinically relevant than single anxiety disorder interventions. They may also have advantages in ease of dissemination and in treating anxiety disorder not otherwise specified. Conclusions. The merits of the various transdiagnostic cognitive-behavioural approaches that have been proposed are reviewed. Such approaches have potential benefits, particularly in striking the balance between completely idiosyncratic formulations and diagnosis-driven treatments of anxiety disorders. However, caution is needed to ensure that transdiagnostic theories and treatments benefit from progress made by research on diagnosis-specific treatments, and further empirical work is needed to identify the shared maintaining processes that need to be targeted in the treatment of anxiety disorders.

The eating disorders provide one of the strongest indications for cognitive behaviour therapy (CBT). This bold claim arises from two sources: first, the fact that eating disorders are essentially cognitive disorders and second, the demonstrated effectiveness of CBT in the treatment of bulimia nervosa, which has led to the widespread acceptance that CBT is the treatment of choice. In this paper the cognitive behavioural approach to the understanding and treatment of eating disorders will be described. A brief summary of the evidence for this account and of the data supporting the efficacy and effectiveness of this form of treatment will be provided. Challenges for the future development and dissemination of the treatment will be identified. © 2008 British Association for Behavioural and Cognitive Psychotherapies.

The DSM-IV scheme for classifying eating disorders1 has certain fundamental flaws. Most prominent among them is the fact that the supposedly “residual” diagnostic category, eating disorder not otherwise specified (EDNOS), is the most common eating disorder encountered in clinical practice: it is more common than the two specified eating disorders, anorexia nervosa (AN) and bulimia nervosa (BN). This is firmly established among adults who are outpatients,2–7 and now Rockert et al. have demonstrated that this is true of those attending a tertiary care outpatient center.8 It also seems to be the case in inpatient settings9 and among adolescent cases.10,11 A second problem concerns the utility of the current diagnostic distinctions. Their arbitrariness is immediately apparent when working with patients. This is especially obvious when one follows patients over time as migration between the eating disorder diagnoses is the norm rather than the exception. Many cases of AN evolve into BN12 or EDNOS, and many cases of BN evolve into EDNOS.13,14We suggest that these changes in clinical state do not truly reflect recovery from one psychiatric disorder and the development of another, as the DSM-IV scheme would suggest, but rather the evolution of a single eating disorder. If we were to tell those patients with EDNOS who have a history of AN and BN that they have had three different psychiatric disorders, two of which they have recovered from, they would react with skepticism. Perhaps we, as clinicians, should do the same. With these flaws in mind, we suggest that there is a need to think afresh about the classification of eating disorders. Specifically, we suggest that we need answers to the following two overarching questions: What is an “eating disorder”? What are the grounds for subdividing the overall category eating disorder? In addition, there is the pragmatic question of what to do about the classification of eating disorders while we are seeking answers to these questions.

Perfectionism can be a problem in its own right and it can impede the progress of treatment of Axis I disorders. This study reports on a preliminary randomised controlled trial of cognitive-behaviour therapy (CBT) for “clinical perfectionism”. Twenty participants were randomly assigned to either immediate treatment (IT) (n=10) or a waitlist (NL) (n=10). Treatment consisted of ten sessions of CBT over eight weeks. Two participants did not complete the follow-up assessments (10%). Fifteen of the original 20 participants (75%) were clinically significantly improved after treatment and the effect size was large (1.8). Treatment gains were maintained at 8-week and 16-week follow-up.

Objective: To examine the relationship between eating disorders and attentional biases. Method: The first study comprised 23 female patients with clinical eating disorders, women with high levels ofanxiety (n = 19), and three female normal control groups comprising low (n = 31), moderate (n = 21), or high levels of shape concern (n = 23). The second study comprised 82 women with clinical eating disorders and 44 healthy controls. All participants completed measures of eating disorder psychopathology and completed a modified pictorial dot-probe task. Results: In the first study, biases were found for negative eating and neutral weight pictures, and for positive eating pictures in women with eating disorders; these biases were greater than those found in anxious and normal controls. The second study replicated these findings and biases were also found for negative and neutral shape stimuli. Conclusion: It is concluded that future research should establish whether such biases warrant specific therapeutic interventions. © 2007 by Wiley Periodicals, Inc. Int J Eat Disord 2007

SynopsisThis paper draws attention to an important adverse outcome in depression, the occurrence of residual symptoms after partial remission. Among patients with definite major depression followed every 3 months to remission and thereafter, residual symptoms reaching 8 or more on the Hamilton Depression Scale 17-item total were present in 32% (19) of the 60 who remitted below major depression by 15 months. The pattern was of mild but typical depressive symptoms. Residual symptoms were more common in subjects with more severe initial illness, but were not related to any other predictors, including longer prior illness, dysthymia, or lower dose of drug treatment during the illness episode. There were weak associations with personality that might have been consequences of symptom presence. Residual symptoms were very strong predictors of subsequent early relapse, which occurred in 76% (13/17) of those with residual symptoms and 25% (10/40) of those without.

Objective: The aim of this study was to examine how alcohol intake changes during and after transdiagnostic cognitive behaviour therapy for eating disorders (CBT-E). Additionally, the paper considers the relationship between alcohol consumption, eating disorder diagnosis and current major depressive episode at the time of first assessment. Method: One hundred and forty nine outpatients with an eating disorder (body mass index over 17.5) were divided into high or low alcohol intake groups (HIG and LIG) according to their intake at pre-treatment assessment. Their alcohol intake and eating disorder psychopathology were examined over the course of treatment and follow-up. Results: There was no difference between the groups on response of the eating disorder to treatment. The HIG significantly reduced their alcohol intake following treatment whilst the intake of the LIG remained stable over the course of treatment and follow-up. There were no group differences in major depression and overall severity of eating disorder at baseline. Conclusions: The response to CBT-E was not influenced by baseline level of alcohol use. The mean alcohol intake of the heavy drinking subjects decreased without being specifically addressed by the treatment. © 2011 Elsevier Ltd.

Little is known about how psychological treatments work. Research on treatment-induced mediators of change may be of help in identifying potential causal mechanisms through which they operate. Outcome-focused randomised controlled trials provide an excellent opportunity for such work. However, certain conceptual and practical difficulties arise when studying psychological treatments, most especially deciding how best to conceptualise the treatment concerned and how to accommodate the fact that most psychological treatments are implemented flexibly. In this paper, these difficulties are discussed, and strategies and procedures for overcoming them are described.

The specific psychopathology of anorexia nervosa and bulimia nervosa is complex in form. Although for many purposes self-report questionnaires are a satisfactory measure of this psychopathology, for detailed psychopathological studies and for investigations into the effects of treatment, more sensitive and flexible assessment measures are required. For this reason a semi-structured interview was developed. This interview, the Eating Disorder Examination, is designed to assess the full range of the specific psychopathology of eating disorders, including these patients' extreme concerns about their shape and weight.

Eight patients with bulimia nervosa were treated using purely behavioral techniques in the absence of explicit cognitive procedures. All were systematically assessed before and after treatment; seven were reassessed at a 1-year follow-up. As a group, they showed substantial improvement in terms of eating habits, a global index of specific psychopathology, and mental state. These changes were comparable to those previously obtained in an Oxford sample of patients using a cognitive behavioral treatment. These findings raise the question as to whether cognitive procedures are necessary to produce change in patients with bulimia nervosa.

Investigated depressed patients' memory for stories. This indicated that although normal Ss showed particularly good recall for units central to the structure of the story, this did not hold for depressed Ss. In contrast, effects of centrality were comparable in high- and low-IQ Ss and effects of imageability of story units were comparable in both depressed and normal Ss. These results are consistent with the hypothesis that depressed patients do not use structure to organize stories when encoding them. A failure to identify central aspects of material and selectively recall them is likely to be a handicap to everyday functioning.
