Evidenzbasierte Diagnostik und Psychotherapie bei Essstörungen

Along with the specific eating-related symptoms, eating disorders are associated with substantial psychological, social and medical sequelae. Overvaluation of body shape and weight and corresponding body dissatisfaction are a central feature of anorexia nervosa (AN) and bulimia nervosa (BN); additionally, these features are also a common symptom in individuals with binge eating disorder (BED). Regarding treatment, cognitive behavioral therapy (CBT) focuses on the distinctive features of the disorder, such as nutritional management and normalization of food intake, alteration of body image disturbances and negative feelings towards one’s body and alteration of the functional relationship between stress, negative emotions and pathological eating behavior. Interpersonal psychotherapy (IPT) instead focuses on the alteration and reduction of interpersonal problems. Following the German S3 guidelines, CBT should be the treatment of choice for BN and BED. Given the scarce empirical evidence of treatment effectiveness for AN, no specific treatment recommendation can be made for AN; however, psychotherapy and not medication should be the treatment of choice.     

Addressing Weight Suppression to Improve Treatment Outcome for Bulimia Nervosa

Cognitive behavioral therapy (CBT) is regarded as the gold-standard treatment for bulimia nervosa (BN), yet despite impressive empirical support for its effectiveness, over 50% of patients fail to achieve abstinence from binge eating and purging by the end of treatment. One factor that may contribute to reduced efficacy rates in CBT is weight suppression (WS; the difference between a person's highest weight ever at their adult height and current weight). A growing body of research indicates that WS in patients with BN may have a clinically significant effect on symptomatology and prognosis. However, the current cognitive behavioral framework for BN does not explicitly acknowledge the role of WS in the onset or maintenance of BN symptoms and does not provide guidance for clinicians on how to address WS during treatment. The relationship between WS, biological pressure to regain lost weight, and the maintenance of BN symptoms suggest that current cognitive behavioral models of BN may be improved by considering the role of WS and exploring needed treatment modifications. Indeed, a reconceptualization of existing models may offer insight into potential strategies that can be used to reduce the susceptibility to treatment dropout, nonresponse, and relapse. It is therefore necessary to consider whether, and how, clinicians' consideration of WS during case conceptualization and treatment planning could serve to improve CBT outcomes. The current review explores ways in which high WS could contribute to poor CBT outcomes, provides preliminary clinical recommendations for incorporating WS into existing cognitive behavioral treatments based on extant data and clinical wisdom, and proposes suggestions for future research needed in this domain.     

Developing an Acceptance-Based Behavioral Treatment for Binge Eating Disorder: Rationale and Challenges

Binge eating disorder (BED), characterized by recurrent eating episodes in which individuals eat an objectively large amount of food within a short time period accompanied by a sense of loss of control, is the most common eating disorder. While existing treatments, such as cognitive behavioral therapy (CBT), produce remission in a large percentage of individuals with BED, room for improvement in outcomes remains. Two reasons some patients may continue to experience binge eating after a course of treatment are: (a) Difficulty complying with the prescribed behavioral components of CBT due to the discomfort of implementing such strategies; and (b) a lack of focus in current treatments on strategies for coping with high levels of negative affect that often drive binge eating. To optimize treatment outcomes, it is therefore crucial to provide patients with strategies to overcome these issues. A small but growing body of research suggests that acceptance-based treatment approaches may be effective for the treatment of binge eating. The goal of the current paper is to describe the development of an acceptance-based group treatment for BED, discuss the structure of the manual and the rationale and challenges associated with integrating acceptance-based strategies into a CBT protocol, and to discuss clinical strategies for successfully implementing the intervention.     

Feasibility,Acceptability, and Preliminary Target Engagement of a Healthy Physical Activity Promotion Intervention for Bulimia Nervosa: Development and Evaluation via Case Series Design

Bulimia nervosa (BN) is characterized by a pattern of binge eating and compensatory behaviors as well as an overemphasis on body weight and shape in self-evaluation. Although cognitive behavioral therapy (CBT) is efficacious, recent reviews suggest that only 30% of patients reach abstinence at posttreatment. One potential reason for these poor outcomes is that CBT fails to adequately reduce elevated negative affect (NA) and shape and weight concern, which have been shown to be correlated with poorer treatment outcomes in BN. Therefore, novel treatment components that focus on improving NA and shape and weight concern are needed in order to enhance outcomes. Promoting physical activity (PA) is a promising avenue through which to reduce NA and improve body image in healthy individuals, other clinical populations (e.g., individuals with depression or anxiety), and individuals with eating disorders. While prescribing PA for individuals with BN has been controversial (due to concerns that exercise maybe be used to compensate for binge episodes or become driven or compulsive), this approach may have many benefits, including promoting healthy lifetime exercise habits that reduce likelihood of relapse through the improvement of emotion regulation skills and weight regulation.Given the promise of PA for targeting key maintenance factors of BN, we developed a 12-session healthy PA promotion intervention for BN and tested initial feasibility, acceptability, and preliminary target engagement in an iterative case series design (n = 3). The treatment provided cognitive-behavioral skills designed to identify, practice, and achieve behavioral goals while asking patients to engage in up to 150 minutes of moderate-to-vigorous PA per week, which was preplanned during each session with the client’s therapist.Results suggested that the healthy PA promotion intervention was both feasible and acceptable to deliver. In addition, the intervention resulted in a clinically significant decrease in BN symptom frequency in each participant. Further, participants showed clinically significant decreases in NA and shape and weight concern.The current study demonstrates that healthy PA interventions can have beneficial effects on BN symptoms, NA, and shape and weight concern. However, due to the small sample size, conclusions must be treated with caution. Future research should investigate additional approaches for promoting healthy PA and include a larger sample in order to further test initial efficacy of this treatment approach.     

A randomized trial comparing the efficacy of cognitive-behavioral therapy for bulimia nervosa delivered via telemedicine versus face-to-face

OBJECTIVE: A major problem in the delivery of mental health services is the lack of availability of empirically supported treatment, particularly in rural areas. To date no studies have evaluated the administration of an empirically supported manual-based psychotherapy for a psychiatric condition via telemedicine. The aim of this study was to compare the relative efficacy and acceptability of a manual-based cognitive-behavioral therapy (CBT) for bulimia nervosa (BN) delivered in person to a comparable therapy delivered via telemedicine. METHOD: One hundred twenty-eight adults meeting DSM-IV criteria for BN or eating disorder-not otherwise specified with binge eating or purging at least once per week were recruited through referrals from clinicians and media advertisements in the targeted geographical areas. Participants were randomly assigned to receive 20 sessions of manual-based, CBT for BN over 16 weeks delivered either face-to-face (FTF-CBT) or via telemedicine (TV-CBT) by trained therapists. The primary outcome measures were binge eating and purging frequency as assessed by interview at the end of treatment, and again at 3- and 12-month follow-ups. Secondary outcome measures included other bulimic symptoms and changes in mood. RESULTS: Retention in treatment was comparable for TV-CBT and FTF-CBT. Abstinence rates at end-of-treatment were generally slightly higher for FTF-CBT compared with TV-CBT, but differences were not statistically significant. FTF-CBT patients also experienced significantly greater reductions in eating disordered cognitions and interview-assessed depression. However, the differences overall were few in number and of marginal clinical significance. CONCLUSIONS: CBT for BN delivered via telemedicine was both acceptable to participants and roughly equivalent in outcome to therapy delivered in person.     

Characteristics and effectiveness of stand-alone body image treatments: a review of the empirical literature

This literature review examined the characteristics and effectiveness of treatments dedicated exclusively to body image. A total of 18 studies met selection criteria. All but one involved at least one cognitive-behavioural therapy (CBT) condition and only three compared CBT to another treatment approach. Twelve studies were conducted with non-clinical, body dissatisfied, participants and only one focussed on eating disordered women. Overall, the interventions were highly effective in improving body image and psychological variables and, to a lesser extent, eating attitude and behaviour. Changes were generally maintained at follow-up. Given their efficacy, more controlled trials of stand-alone body image treatments in clinical populations are needed. Investigating approaches other than CBT may open fruitful avenues of body image treatment.     

Dialectical Behavior Therapy of Anorexia and Bulimia Nervosa Among Adolescents: A Case Series

The aim of this study was to describe a case series of adolescents (mean age = 16.5 years, SD = 1.0) with anorexia nervosa (AN) and bulimia nervosa (BN) who received dialectical behavior therapy (DBT). Twelve outpatients with AN and BN took part in 25 weeks of twice weekly therapy consisting of individual therapy and a skills training group. Family members were involved in the treatment. The patients were compared pre- and posttreatment on behavioral symptoms of AN and BN and symptoms of general psychopathology using standardized instruments (Structured Inventory for Anorectic and Bulimic Syndromes, Eating Disorder Inventory-2, The Symptom Checklist-90-Revised). Posttreatment, significant improvements in behavioral symptoms of eating disorder and symptoms of psychopathology were identified. The application of DBT adapted for the treatment of AN and BN among adolescents was associated with a decrease in behavioral symptoms of eating disorders and symptoms of general psychopathology. However, randomized controlled studies are required to prove the efficacy of this approach.     

Body image interventions in cognitive-behavioural therapy of binge-eating disorder: a component analysis

The present study sought to investigate effects of body exposure in the treatment of binge-eating disorder (BED). Cognitive-behavioural therapy with a body exposure component (CBT-E) was compared with CBT with a cognitive restructuring component focused on body image (CBT-C). Twenty-eight patients diagnosed with BED were randomly assigned to CBT-E or CBT-C, both delivered in a group format. Negative automatic thoughts about one's body, dysfunctional assumptions about shape and weight, and body dissatisfaction were assessed using experimental thought-sampling techniques, a clinical interview (Eating Disorder Examination), and self-report questionnaires. At posttreatment and at 4-month follow-up, CBT-E and CBT-C were equally effective in improving body image disturbance on all indicators assessed. Both CBT-E and CBT-C produced substantial and stable improvements in the specific and general eating disorder psychopathology. Results suggest that both treatment components are equally effective in the treatment of BED.     

Body image disturbance in patients with borderline personality disorder: Impact of eating disorders and perceived childhood sexual abuse

Body image disturbances occur in women with borderline personality disorder (BPD). Systematic research on these characteristics in well-defined BPD groups is lacking. It is unknown, if the disturbances are related to eating disorders and childhood sexual abuse (CSA), which frequently co-occur in patients with BPD. In the present study, cognitive-affective and behavioral components of body image for 89 female patients with BPD (49 with lifetime eating disorders) and 41 healthy participants were assessed via Body Image Avoidance Questionnaire (BIAQ) and Multidimensional Body-Self Relations Questionnaire (MBSRQ). Within the BPD group, 43 patients reported a history of CSA. Compared to healthy controls, BPD patients reported significantly more negative scores in the BIAQ and the MBSRQ. Both a history of CSA and a comorbid eating disorder were independently associated with an even more negative body image. Results suggest a disturbance of cognitive-affective and behavioral components of body image in female BPD patients.     

Multidimensional body image comparisons among patients with eating disorders,body dysmorphic disorder,and clinical controls: A multisite study

Body image disturbance is considered a core characteristic of eating disorders and body dysmorphic disorder (BDD), however its definition has been unclear within the literature. This study examined the multidimensional nature of body image functioning among individuals with either anorexia nervosa (AN; n = 35), bulimia nervosa (BN; n = 26), or BDD (n = 56), relative to female (n = 34) and male (n = 36) psychiatric controls. Participants were recruited from 10 treatment centers in the United States and England and completed psychometrically validated and standardized self-report measures of body image. Overall, the AN, BN, and BDD groups were characterized by significantly elevated disturbances in most body image dimensions relative to their gender-matched clinical controls. There was variability, however, in the comparisons among the three groups of interest, including foci of body dissatisfaction and body image coping patterns. On omnibus indices of body image disturbance and body image quality of life, patients with BDD reported more body image impairment than those with eating disorders. Although AN, BN, and BDD are characterized by body image disturbances, similar and partially distinctive cognitive, behavioral, and emotional elements of body image functioning exist among these groups. The study's empirical and clinical implications are considered.     

Cognitive-Behavioral Therapy for Adolescent Body Dysmorphic Disorder

The onset of appearance-related concerns associated with body dysmorphic disorder (BDD) typically occurs in adolescence, and these concerns are often severe enough to interfere with normal development and psychosocial functioning. Cognitive behavioral therapy (CBT) is an effective treatment for adults with BDD. However, no treatment studies focusing on adolescents with BDD have been conducted. The need for an effective treatment in this population led to the development of a brief CBT protocol with family involvement. The treatment focuses on enhancing an adolescent's quality of life through the reduction of maladaptive thoughts and behaviors, and incorporates skills training and parent training. Similar treatment packages have already been shown to be efficacious for children and adolescents with similar disorders, such as obsessive-compulsive disorder and social phobia. The following case illustrates the application of this brief CBT protocol for BDD in an adolescent, and highlights clinical considerations needed when adapting CBT for a pediatric population. Treatment was associated with clinically significant improvement in symptoms of BDD, self-esteem, depression, and quality of life. This report extends extant literature by suggesting that CBT may be a helpful treatment for adolescents with BDD.     

Perfectionistic self-presentation, body image, and eating disorder symptoms

A specific model for eating disorder symptoms involving perfectionistic self-presentation and two different moderators (i.e., body image evaluation and body image investment) was tested. Participants completed measures of perfectionistic self-presentation, body image dysfunction, and eating disorder symptoms. Findings indicated that all three dimensions of perfectionistic self-presentation were associated with eating disorder symptoms. Results also showed that perfectionistic self-presentation predicted eating disorder symptoms in women who were dissatisfied with their bodies, but that it did not predict eating problems in women who liked their bodies and felt there was little or no discrepancy between their actual and ideal appearances. Body image investment did not moderate the relationship between perfectionistic self-presentation and eating disorder symptoms, suggesting that ego-involvement alone is insufficient to promote eating disturbance in the context of perfectionism. The importance of self-presentation components of perfectionism and specific body image difficulties in predicting eating disorder symptoms are discussed.     

The Cognitive‐Behavioural Theory and Treatment of Bulimia Nervosa: An Examination of Treatment Mechanisms and Future Directions

Enhanced cognitive‐behavioural therapy (CBT‐E) is the current treatment of choice for bulimia nervosa. While the cognitive‐behavioural theory and treatment of bulimia nervosa have made a substantial contribution to our understanding of the disorder, approximately half of patients treated with CBT‐E fail to achieve remission of binge eating and purging. There is evidence showing that mechanisms proposed by the CBT‐E model are associated with binge eating and purging symptoms, and therefore likely important targets for treatment. To identify future directions in improving the efficacy of this treatment, and informed by a model of the client change process, we review the evidence for the hypothesised treatment mechanisms of CBT‐E. We conclude that while the proposed treatment mechanisms of CBT‐E largely change over the course of treatment, there is limited evidence that the treatment manipulations of CBT‐E are responsible for the specific changes in the proposed treatment mechanisms. In addition, given a lack of research in this area, we could find no evidence that changes in the additional treatment mechanisms outlined in CBT‐E are associated with changes in the core symptomatology of binge eating and purging. Based on these findings, we recommend that future efforts are directed towards understanding the client change process in CBT‐E and outline three clear directions for research.     

Effectiveness of cognitive behavioral therapy on the signs,symptoms and clinical consequences of premature ejaculation

The purpose of this research was to assess the effectiveness of cognitive behavioral therapy (CBT) on the signs, symptoms, and clinical‐sexual consequences of premature ejaculation, including sexual esteem, sexual anxiety, sexual depression, sexual fear, and sexual satisfaction of patients and their wives. Fifteen patients with premature ejaculation were selected and received cognitive behavioral therapy of eight to 12 sessions. Finally, the data collected from 12 patients were analyzed using paired t‐tests. The results of the analysis showed that all of the variables changed after the treatment. All of the changes were statistically significant with a tendency towards improvement. CBT can be a more popular and effective treatment provided to patients suffering from premature ejaculation.     

Group Cognitive Behavioral Treatment for PTSD: Treatment of Motor Vehicle Accident Survivors

Individual cognitive behavioral therapies (CBT) are now considered the first-line treatment for posttraumatic stress disorder (PTSD; Foa, Keane, & Friedman, 2000). As mental health reimbursement becomes more restricted, it is imperative that we adapt individual-format therapies for use in a small group format. Group therapies have a number of advantages, including provision of a natural support group, the ability to reach more patients, and greater cost efficiency. In this article, we describe the development of a group CBT for PTSD in the aftermath of a serious motor vehicle accident (MVA). Issues unique to the group treatment format are discussed, along with special considerations such as strategies to reduce the potential for triggering reexperiencing symptoms during group sessions. A case example is presented, along with discussion of group process issues. Although still in the early stages, this group CBT may offer promise as an effective treatment of MVA-related PTSD.     

Ecological momentary assessment of bulimia nervosa: Does dietary restriction predict binge eating?

The purpose of this study was to examine the relationship between caloric restriction (CR) and binge eating (BE) using ecological momentary assessment (EMA). Participants included 133 women with bulimia nervosa (BN) who completed an EMA protocol for 2 weeks. Logistic regression analyses tested whether CR increased the probability of BE episodes. The results revealed that the odds of BE increased on the day that restriction occurred as well as on the following day. In addition, both restriction and BE on one day predicted the likelihood of BE the subsequent day, but restriction for two days prior to the episode failed to add additional information for predicting BE. These findings support the cognitive behavioral therapy (CBT) model of BN, suggesting that self-reported dietary restriction is predictive of subsequent BE episodes, and that reducing dietary restriction in treatment may lead to improvements in bulimic symptoms.     

Integrative time-limited group therapy for bulimia nervosa.

This article presents an integrative group therapy model for the treatment of bulimia nervosa (BN) and describes the 12-session format, incorporating components of cognitive-behavioral therapy (CBT), psychoeducation, interpersonal therapy (IPT), and relational therapy (RT), in detail. Previous reports have found CBT, IPT, and RT to be effective approaches for BN when used separately. The integrative approach may have the advantage of achieving symptom reduction by two different mediating mechanisms, those that directly affect eating behaviors and those that address the interpersonal and relational context in which the disordered eating has developed. The group approach makes use of the peer group in providing new opportunities for self-exploration and self-correction. One advantage of an integrative model is patients' exposure to several different treatment modalities from which they can identify specific approaches that are most helpful to their recovery. This identification is valuable in directing future treatment, if needed. Pilot data for this approach are presented.     

Cognitive Behavior Therapy in First-Episode Psychosis With a Focus on Depression,Anxiety, and Self-Esteem

Although several reviews show that cognitive behavioral therapy (CBT) is an effective treatment for patients with chronic psychosis, the effects of CBT on patients with a first-episode psychosis are less clear. Patients undergoing a first-episode psychosis are unique in that not only are they struggling with the symptoms of the disease, but also the realization of the diagnosis. Understanding how the disease will impact their lives with respect to changes in social goals, roles, and status can also lead to depression, anxiety and low self-esteem. The main aim of the present study is to describe two clinical cases in order to demonstrate the application of CBT in first-episode psychosis patients in an early stage of their psychosis. The two cases are individuals who were in an ongoing CBT trial for first-episode psychosis patients with symptoms of social anxiety, depression, and low self-esteem. Individual case formulations based on these symptoms were developed. Psychoeducation, normalizing, evaluation of negative automatic thoughts and dysfunctional schematic beliefs, and focusing on the negative consequences of safety behavior were the main treatment targets in attempting to improve the patients’ symptoms and functioning. Both patients showed improvement in depressive symptoms, self-esteem, and general functioning. The cases described suggest that treatment designed to target depression, anxiety, and self-esteem in patients with first-episode psychosis could have potential beneficial effects; specific studies of this approach are recommended.     

Perceived acceptability of anorexia and bulimia in women with and without eating disorder symptoms

Perceptions of the acceptability of eating‐disordered behaviour were examined in young adult women with (n = 44) and without (n = 268) eating disorder symptoms. All participants viewed vignettes of anorexia nervosa (AN) and bulimia nervosa (BN) and responded to the same series of questions—addressing different possible ways in which the conditions described might be seen to be acceptable—in relation to each vignette. Participants with eating disorder symptoms perceived eating‐disordered behaviour to be more acceptable than asymptomatic participants, and this was the case for both AN and BN vignettes and for a range of different items. Differences on items tapping the perception that it ‘might not be too bad’ to have an eating disorder and that an eating disorder is ‘nothing to be concerned about’ were particularly pronounced. The findings could not be accounted for by between‐group differences in body weight. The findings indicate the ambivalence towards eating‐disordered behaviour that exists among a subgroup of young women in the community and the clear association between such ambivalence and actual eating disorder symptoms. The perceived acceptability of eating‐disordered behaviour may need to be addressed in prevention and early‐intervention programs for eating disorders.
