Abstract
INTRODUCTION Web-based guided self-help cognitive behavioral therapy-enhanced (CBT-E) is a 12-weeks, 12-sessions, digitalized version of part II of the self-help book Overcoming Binge Eating. This intervention is effective when offered under controlled circumstances in a randomized-controlled-trial. It is unknown how patients with binge-eating disorder (BED) respond to this intervention when offered in real-world clinical-settings. The aim of this study is to examine post-intervention effectiveness of guided self-help CBT-E for BED in real-world settings. METHOD The present study used a cohort-design examining the effectiveness of web-based guided self-help CBT-E according to an intention-to-treat (ITT) analysis. BED patients (n = 278) were assessed pre- and post-intervention. The primary outcome was reduction in binge-eating episodes. Other outcomes were full-recovery (EDE-Q score <2.77 and abstinence from binge-eating episodes), impaired psychosocial functioning, defined as secondary impairment, and general psychopathology post-intervention. RESULTS The number of binge-eating episodes reduced by an average of 16 binge-eating episodes per 4 weeks pre-intervention to five binge-eating episodes during the last 4 weeks of treatment. Abstinence from binge eating was reported by 30%, and 28% reported full recovery. Effect sizes (Cohen's d) were large (d ≥ 1.0) for all outcome measures. There were no differences in outcomes between the ITT and the completers sample. DISCUSSION Guided self-help CBT-E is associated with significant improvements. The effects of guided self-help CBT-E offered in a real-world-setting are comparable to self-help CBT-E offered in a randomized-controlled-trial. However, it should be noted that comparisons with randomized-controlled-trials requires caution. Longer-term follow-up data are necessary to measure persistence of treatment benefits. PUBLIC SIGNIFICANCE Offering CBT-E as a web-based guided self-help intervention has several benefits for patients with BED. Guided self-help CBT-E is associated with significant improvements on the short term when offered in real-world clinical settings.

Abstract
OBJECTIVE Eating disorders (EDs) were once conceptualized as primarily affecting affluent, White women, a misconception that informed research and practice for many years. Abundant evidence now discredits this stereotype, but it is unclear if prevailing "evidence-based" treatments have been evaluated in samples representative of the diversity of individuals affected by EDs. Our goal was to evaluate the reporting, inclusion, and analysis of sociodemographic variables in ED psychotherapeutic treatment randomized controlled trials (RCTs) in the US through 2020. METHODS We conducted a systematic review of ED psychotherapeutic treatment RCTs in the US and examined the reporting and inclusion of gender identity, age, race/ethnicity, sexual orientation, and socioeconomic status (SES) of enrolled participants, as well as recruitment methods, power analyses, and discussion of limitations and generalizability. RESULTS Our search yielded 58 studies meeting inclusion criteria dating back to 1985. Reporting was at times incomplete, absent, or centered on the racial/gender majority group. No studies reported gender diverse participants, and men and people of color were underrepresented generally, with differences noted across diagnoses. A minority of papers considered sociodemographic variables in analyses or acknowledged limitations related to sample characteristics. Some progress was made across the decades, with studies increasingly providing full racial and ethnic data, and more men included over time. Although racial and ethnic diversity improved somewhat, progress appeared to stall in the last decade. DISCUSSION We summarize findings, consider context and challenges for RCT researchers, and offer suggestions for researchers, journal editors, and reviewers on improving representation, reporting, and analytic practices. PUBLIC SIGNIFICANCE Randomized controlled trials of eating disorder psychotherapeutic treatment in the US are increasingly reporting full race/ethnicity data, but information on SES is inconsistent and sexual orientation absent. White women still comprise the overwhelming majority of participants, with few men and people of color, and no gender-diverse individuals. Findings underscore the need to improve reporting and increase representation to ensure evidence-based treatments are effective across and within diverse groups.

Abstract
BACKGROUND Research into psychotherapy for binge-eating disorder (BED) has focused mainly on cognitive behavioural therapies, but efficacy, failure to abstain, and dropout rates continue to be problematic. The experience of negative emotions is among the most accurate predictors for the occurrence of binge eating episodes in BED, suggesting benefits to exploring psychological treatments with a more specific focus on the role of emotion. The present study aimed to explore the feasibility of individual emotion-focused therapy (EFT) as a treatment for BED by examining the outcomes of a pilot randomised wait-list controlled trial. METHODS Twenty-one participants were assessed using a variety of feasibility measures relating to recruitment, credibility and expectancy, therapy retention, objective binge episodes and days, and binge eating psychopathology outcomes. The treatment consisted of 12 weekly one-hour sessions of EFT for maladaptive emotions over 3 months. A mixed model approach was utilised with one between effect (group) using a one-way analysis of variance (ANOVA) to test the hypothesis that participants immediately receiving the EFT treatment would demonstrate a greater degree of improvement on outcomes relating to objective binge episodes and days, and binge eating psychopathology, compared to participants on the EFT wait-list; and one within effect (time) using a repeated-measures ANOVA to test the hypothesis that participation in the EFT intervention would result in significant improvements in outcome measures from pre to post-therapy and then maintained at follow-up. RESULTS Recruitment, credibility and expectancy, therapy retention outcomes indicated EFT is a feasible treatment for BED. Further, participants receiving EFT demonstrated a greater degree of improvement in objective binge episodes and days, and binge eating psychopathology compared to EFT wait-list control group participants. When participants in the EFT wait-list control group then received treatment and outcomes data were combined with participants who initially received the treatment, EFT demonstrated significant improvement in objective binge episodes and days, and binge eating psychopathology for the entire sample. CONCLUSIONS These findings provide further preliminary evidence for the feasibility of individual EFT for BED and support more extensive randomised control trials to assess efficacy. TRIAL REGISTRATION The study was retrospectively registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12620000563965 ) on 14 May 2020.

Int J Eat Disord 2020; 53:1353-1376. [PMID: 32583527 DOI: 10.1002/eat.23297] [Citation(s) in RCA: 44] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 03/17/2020] [Accepted: 03/19/2020] [Indexed: 12/15/2022]
Abstract
OBJECTIVE Long-term effectiveness is a critical aspect of the clinical utility of a treatment; however, a meta-analytic evaluation of psychological and medical treatments for binge-eating disorder (BED), including weight loss treatments, is outstanding. This meta-analysis sought to provide a comprehensive evaluation of the long-term effectiveness in diverse treatments for BED regarding a range of clinically relevant outcomes. METHOD Based on a systematic search up to February 2018, 114 published and unpublished randomized-controlled (RCTs), nonrandomized, and uncontrolled treatment studies, totaling 8,862 individuals with BED (DSM-IV, DSM-5), were identified and analyzed using within-group random-effect modeling. RESULTS Effectiveness (regarding binge-eating episodes and abstinence, eating disorder and general psychopathology) up to 12 months following treatment was demonstrated for psychotherapy, structured self-help treatment, and combined treatment, while the results regarding body weight reduction were inconsistent. These results were confirmed in sensitivity analyses with RCTs on the most common treatments-cognitive-behavioral therapy and self-help treatment based on this approach. Follow-up intervals longer than 12 months were rarely reported, mostly supporting the long-term effectiveness of psychotherapy. Few follow-up data were available for pharmacotherapy, and behavioral and self-help weight loss treatment, while follow-up data were lacking for pharmacological and surgical weight loss treatment. Study quality varied widely. DISCUSSION This comprehensive meta-analysis demonstrated the medium-term effectiveness of psychotherapy, structured self-help treatment, and combined treatment for patients with BED, and supported the long-term effectiveness of psychotherapy. The results were derived from uncontrolled comparisons over time. Further long-term high quality research on psychological and medical treatments for BED is required.

Abstract
OBJECTIVE Standardized effect sizes reported in previous meta-analyses of binge-eating disorder (BED) treatment are sometimes difficult to interpret and are criticized for not being a useful indicator of the clinical importance of a treatment. Abstinence from binge eating is a clinically relevant component of a definition of a successful treatment outcome. This meta-analysis estimated the prevalence of patients with BED who achieved binge eating abstinence following psychological or behavioral treatments. METHOD This meta-analysis included 39 randomized controlled trials, with 65 treatment conditions and 2,349 patients. Most conditions comprised cognitive-behavioral therapy (n = 40). Pooled event rates were calculated at posttreatment and follow-up using random effects models. RESULTS The total weighted percentage of treatment-completers who achieved abstinence at posttreatment was 50.9% (95% CI = 43.9, 57.8); this estimate was almost identical at follow-up (50.3%; 95% CI = 43.6, 56.9). The total weighted percentage of patients who achieved abstinence at posttreatment in the intention-to-treat analysis (all randomized patients) was 45.1% (95% CI =40.7, 49.5), and at follow-up it was 42.3% (95% CI =37.5, 47.2). Interpersonal psychotherapy (IPT) produced the highest abstinence rates. Clinician-led group treatments produced significantly higher posttreatment (but not follow-up) abstinence estimates than guided self-help treatments. Neither timeframe for achieving abstinence, assessment type (interview/questionnaire), number of treatment sessions, patient demographics, nor trial quality, moderated the abstinence estimates. DISCUSSION The present findings demonstrate that 50% of patients with BED do not fully respond to treatment. Continued efforts toward improving eating disorder treatments are needed.

Abstract
OBJECTIVE In the current meta-analysis, we review the effect of group psychotherapy compared to both wait-list controls and other active treatments for adults with eating disorders (EDs). METHOD Twenty-seven randomized controlled trials (RCTs) that provide direct comparisons with a total of 1,853 participants were included. RESULTS Group psychotherapy is significantly more effective than wait-list controls at achieving abstinence rates of binge eating and/or purging (RR = 5.51, 95% CI: 3.73, 8.12), decreasing the frequency of binge eating and/or purging (g = 0.70, 95% CI: 0.51, 0.90), and reducing related ED psychopathology (g = 0.49, 95% CI: 0.32, 0.66) after treatment. The effects of group psychotherapy and other active treatments (e.g., behavioral weight loss, self-help, individual psychotherapy) did not differ on any outcome at post-treatment or at follow-ups. Group cognitive behavioral therapy (CBT) and other forms of group psychotherapy did not differ significantly on outcomes at any time point. DISCUSSION Additional research is needed to evaluate other group psychotherapy approaches, along with CBT, to provide more evidence-based treatment options for individuals with an ED. Group psychotherapy appears as effective as other common treatments and is perhaps more cost-effective than the most popular treatment, individual psychotherapy. Only 8.33% of comparisons in the current meta-analysis had at least 80% power to detect a moderate effect (d = .50) and we recommend that future RCTs be adequately powered.

Abstract
OBJECTIVE Meta-analyses have documented the efficacy of cognitive-behavioral therapy (CBT) for reducing symptoms of eating disorders. However, it is not known whether CBT for eating disorders can also improve quality of life (QoL). This meta-analysis therefore examined the effects of CBT for eating disorders on subjective QoL and health-related quality of life (QoL). METHOD Studies that assessed QoL before and after CBT for eating disorders were searched in the PsycInfo and Medline database. Thirty-four articles met inclusion criteria. Pooled within and between-groups Hedge's g were calculated at post-treatment and follow-up for treatment changes on both subjective and HRQoL using a random effects model. RESULTS CBT led to significant and modest improvements in subjective QoL and HRQoL from pre to post-treatment and follow-up. CBT led to greater subjective QoL improvements than inactive (i.e., wait-list) and active (i.e., a combination of bona fide therapies, psychoeducation) comparisons. CBT also led to greater HRQoL improvements than inactive, but not active, comparisons. Prepost QoL improvements were larger in studies that delivered CBT individually and by a therapist or according to the cognitive maintenance model of eating disorders (CBT-BN or CBT-E); though this was not replicated at follow-up CONCLUSIONS: Findings provide preliminary evidence that CBT for eating disorders is associated with modest improvements in QOL, and that CBT may be associated with greater improvements in QOL relative to comparison conditions.

Abstract
BACKGROUND Evidence-based self-help is a recommended first stage of treatment for mild-moderate eating disorders. The provision of guidance enhances outcome. The literature evaluating exclusively 'guided' self-help (GSH) has not been systematically reviewed. METHODS The aim was to establish the effectiveness of GSH for reducing global eating disorder psychopathology and abstinence from binge eating, compared with controls. Results were pooled using random effects meta-analysis and heterogeneity explored using metaregression. RESULTS Thirty randomised controlled trials met the inclusion criteria. Results showed an overall effect of GSH on global eating disorder psychopathology (-0.46) and binge abstinence (-0.20). There was strong evidence for an association between diagnosis of binge eating disorder and binge abstinence. DISCUSSION Current interventions need to be adapted to address features other than binge eating. Further research is required to help us understand the effectiveness of GSH in children and young people, invariably high dropout rates and how technology can enhance interventions.

Abstract
BACKGROUND The best treatment options for binge-eating disorder are unclear. PURPOSE To summarize evidence about the benefits and harms of psychological and pharmacologic therapies for adults with binge-eating disorder. DATA SOURCES English-language publications in EMBASE, the Cochrane Library, Academic OneFile, CINAHL, and ClinicalTrials.gov through 18 November 2015, and in MEDLINE through 12 May 2016. STUDY SELECTION 9 waitlist-controlled psychological trials and 25 placebo-controlled trials that evaluated pharmacologic (n = 19) or combination (n = 6) treatment. All were randomized trials with low or medium risk of bias. DATA EXTRACTION 2 reviewers independently extracted trial data, assessed risk of bias, and graded strength of evidence. DATA SYNTHESIS Therapist-led cognitive behavioral therapy, lisdexamfetamine, and second-generation antidepressants (SGAs) decreased binge-eating frequency and increased binge-eating abstinence (relative risk, 4.95 [95% CI, 3.06 to 8.00], 2.61 [CI, 2.04 to 3.33], and 1.67 [CI, 1.24 to 2.26], respectively). Lisdexamfetamine (mean difference [MD], -6.50 [CI, -8.82 to -4.18]) and SGAs (MD, -3.84 [CI, -6.55 to -1.13]) reduced binge-eating-related obsessions and compulsions, and SGAs reduced symptoms of depression (MD, -1.97 [CI, -3.67 to -0.28]). Headache, gastrointestinal upset, sleep disturbance, and sympathetic nervous system arousal occurred more frequently with lisdexamfetamine than placebo (relative risk range, 1.63 to 4.28). Other forms of cognitive behavioral therapy and topiramate also increased abstinence and reduced binge-eating frequency and related psychopathology. Topiramate reduced weight and increased sympathetic nervous system arousal, and lisdexamfetamine reduced weight and appetite. LIMITATIONS Most study participants were overweight or obese white women aged 20 to 40 years. Many treatments were examined only in single studies. Outcomes were measured inconsistently across trials and rarely assessed beyond end of treatment. CONCLUSION Cognitive behavioral therapy, lisdexamfetamine, SGAs, and topiramate reduced binge eating and related psychopathology, and lisdexamfetamine and topiramate reduced weight in adults with binge-eating disorder.

Abstract
This article reviews the most recent treatment literature for anorexia nervosa, bulimia nervosa, and binge eating disorder and serves as a guide for recommended readings and therapist resources. The primary focus is on empirically tested treatment modalities; for each of these approaches reviewed, the theoretical background, nature of the intervention, and existing empirical support are summarized. The article also presents less researched, albeit promising, approaches to eating disorder treatment, describing the rationale and available research. A focus on multicultural issues, including the paucity of eating disorder treatment research among participants of color, and suggestions for building research and enhancing treatment effectiveness with ethnic minority clients, is incorporated throughout. Recommendations concerning pressing research needs are made, and a summary of clinical recommendations for each disorder is formulated.

Abstract
BACKGROUND Multiple sclerosis (MS) is an inflammatory and neurodegenerative disease of the central nervous system of potential autoimmune origin that is frequently associated with psychological disorders and cognitive deficits, as well as with fatigue, stress, and psychosocial burden. These factors often cause decreased quality of life, social withdrawal, and unemployment. We describe the development of a cognitive-behavioral group intervention based on the concept of metacognition and evaluation of the feasibility and acceptance of the program as a rehabilitation tool. METHODS Metacognitive Training in MS (MaTiMS) consists of six modules, each 90 minutes in duration. We tested acceptance and design of the program in six focus groups (entire sample, n = 27). Framework analysis of transcripts was used to identify key topics and categories. Program modules were revised in accordance with appropriate recommendations of focus group members. We subsequently evaluated MaTiMS in two groups (n = 5, n = 6) in a rehabilitation center. Neuropsychological functioning as well as coping self-efficacy, depression, stress, perceived cognitive deficit, fatigue, and quality of life were assessed. Acceptance of MaTiMS from the patient perspective was also studied. RESULTS The modules were highly accepted by patients. Pre-post assessments showed significant improvements in the Coping Self Efficacy Scale (P = .007), the Würzburger Fatigue Inventory for MS Score (P = .028), and the Hamburg Quality of Life Questionnaire in Multiple Sclerosis Mood subscale (P = .046). CONCLUSIONS These preliminary results suggest that MaTiMS represents a feasible psychological group training program that may foster improvements in self-efficacy, fatigue, and mood. The next step will be an evaluation of the program in a randomized controlled trial.

Treatment of binge eating disorder in racially and ethnically diverse obese patients in primary care: randomized placebo-controlled clinical trial of self-help and medication. Behav Res Ther 2014; 58:1-9. [PMID: 24857821 DOI: 10.1016/j.brat.2014.04.002] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2014] [Revised: 04/04/2014] [Accepted: 04/09/2014] [Indexed: 11/30/2022]
Abstract
The objective was to determine whether treatments with demonstrated efficacy for binge eating disorder (BED) in specialist treatment centers can be delivered effectively in primary care settings to racially/ethnically diverse obese patients with BED. This study compared the effectiveness of self-help cognitive-behavioral therapy (shCBT) and an anti-obesity medication (sibutramine), alone and in combination, and it is only the second placebo-controlled trial of any medication for BED to evaluate longer-term effects after treatment discontinuation. 104 obese patients with BED (73% female, 55% non-white) were randomly assigned to one of four 16-week treatments (balanced 2-by-2 factorial design): sibutramine (N = 26), placebo (N = 27), shCBT + sibutramine (N = 26), or shCBT + placebo (N = 25). Medications were administered in double-blind fashion. Independent assessments were performed monthly throughout treatment, post-treatment, and at 6- and 12-month follow-ups (16 months after randomization). Mixed-models analyses revealed significant time and medication-by-time interaction effects for percent weight loss, with sibutramine but not placebo associated with significant change over time. Percent weight loss differed significantly between sibutramine and placebo by the third month of treatment and at post-treatment. After the medication was discontinued at post-treatment, weight re-gain occurred in sibutramine groups and percent weight loss no longer differed among the four treatments at 6- and 12-month follow-ups. For binge-eating, mixed-models revealed significant time and shCBT-by-time interaction effects: shCBT had significantly lower binge-eating frequency at 6-month follow-up but the treatments did not differ significantly at any other time point. Demographic factors did not significantly predict or moderate clinical outcomes. Our findings suggest that pure self-help CBT and sibutramine did not show long-term effectiveness relative to placebo for treating BED in racially/ethnically diverse obese patients in primary care. Overall, the treatments differed little with respect to binge-eating and associated outcomes. Sibutramine was associated with significantly greater acute weight loss than placebo and the observed weight-regain following discontinuation of medication suggests that anti-obesity medications need to be continued for weight loss maintenance. Demographic factors did not predict/moderate clinical outcomes in this diverse patient group.

Abstract
OBJECTIVE The objective was to examine the effectiveness of a self-help treatment as a first line primary care intervention for binge eating disorder (BED) in obese patients. This study compared the effectiveness of a usual care plus self-help version of cognitive behavioral therapy (shCBT) to usual care (UC) only in ethnically/racially diverse obese patients with BED in primary care settings in an urban center. METHOD 48 obese patients with BED were randomly assigned to either shCBT (N = 24) or UC (N = 24) for four months. Independent assessments were performed monthly throughout treatment and at post-treatment. RESULTS Binge-eating remission rates did not differ significantly between shCBT (25%) and UC (8.3%) at post-treatment. Mixed models of binge eating frequency determined using the Eating Disorder Examination (EDE) revealed significant decreases for both conditions but that shCBT and UC did not differ. Mixed models of binge eating frequency from repeated monthly EDE-questionnaire assessments revealed a significant treatment-by-time interaction indicating that shCBT had significant reductions whereas UC did not during the four-month treatments. Mixed models revealed no differences between groups on associated eating disorder psychopathology or depression. No weight loss was observed in either condition. CONCLUSIONS Our findings suggest that pure self-help CBT did not show effectiveness relative to usual care for treating BED in obese patients in primary care. Thus, self-help CBT may not have utility as a front-line intervention for BED for obese patients in primary care and future studies should test guided-self-help methods for delivering CBT in primary care generalist settings.

Abstract
OBJECTIVE Binge eating disorder (BED) is prevalent among individuals from minority racial/ethnic groups and among individuals with lower levels of education, yet the efficacy of psychosocial treatments for these groups has not been examined in adequately powered analyses. This study investigated the relative variance in treatment retention and posttreatment symptom levels accounted for by demographic, clinical, and treatment variables as moderators and predictors of outcome. METHOD Data were aggregated from 11 randomized, controlled trials of psychosocial treatments for BED conducted at treatment sites across the United States. Participants were N = 1,073 individuals meeting criteria for BED including n = 946 Caucasian, n = 79 African American, and n = 48 Hispanic/Latino participants. Approximately 86% had some higher education; 85% were female. Multilevel regression analyses examined moderators and predictors of treatment retention, Eating Disorder Examination (EDE) global score, frequency of objective bulimic episodes (OBEs), and OBE remission. RESULTS Moderator analyses of race/ethnicity and education were nonsignificant. Predictor analyses revealed African Americans were more likely to drop out of treatment than Caucasians, and lower level of education predicted greater posttreatment OBEs. African Americans showed a small but significantly greater reduction in EDE global score relative to Caucasians. Self-help treatment administered in a group showed negative outcomes relative to other treatment types, and longer treatment was associated with better outcome. CONCLUSIONS Observed lower treatment retention among African Americans and lesser treatment effects for individuals with lower levels of educational attainment are serious issues requiring attention. Reduced benefit was observed for shorter treatment length and self-help administered in groups.

Abstract
OBJECTIVE The goals of the present study were (a) to analyse the efficacy of short-term (10 weeks) psychoeducation group treatment in patients with binge eating disorder (BED) and eating disorders not otherwise specified (EDNOS), and (b) to analyse the determinants of the success of psychoeducation on single outcome measures. METHODS The sample included all patients seeking help for their binge behaviour at the Psychiatric Clinic of the Teaching Hospital of Udine. They all met the inclusion DSM-IV TR criteria for a diagnosis of EDNOS or BED. Eating attitudes were measured with the Eating Disorder Inventory (EDI-2), which includes three scales: bulimia (EDI-BU), body dissatisfaction (EDI-BD) and drive to thinness (EDI-DT). Other psychometric instruments were the Hospital Anxiety and Depression Scale and the Toronto Alexithymia Scale (TAS-20). Psychoeducation group treatment was carried out in an outpatient setting. It consisted in 10 weekly sessions of group therapy. At the end of this period, patients who maintained an eating disorder (ED) were asked to participate to an extension protocol, which included two fortnightly sessions followed by further monthly sessions for a period of 8 months. RESULTS 98 patients were originally included in the protocol. Of these, 54 met the criteria for BED and 44 for EDNOS. At the end of the treatment, 30 patients (30.6 %) no longer suffered from an ED. All patients showed significant improvements on several other outcome measures (frequency of binges, BMI, bulimic traits, body dissatisfaction, anxiety, depression and alexithymia). The probability to recover from an ED was greater in subjects with higher scores of both BMI (p = 0.009) and EDI-BU (p = 0.002), together with lower TAS-20 scores at t0 (p = 0.003); the probability to reduce the frequency of binges was greater in subjects with higher frequency of binges at t0 (p < 0.0001); the improvement in the EDI-BD scores was negatively associated (p = 0.005) with BMI at t0, and positively associated with scores at t0 of EDI-BD (p < 0.0001); the improvement in the EDI-BU scores at t1 was associated with the EDI-BU scores at t0 (p < 0.0001). 53 patients accepted to participate to the continuation phase; of these, 32 were assessed at the end of the period. About 41 % of the latter obtained a recovery from an ED, with a further reduction of the episodes of binges and an improvement of BMI scores. CONCLUSION This study may demonstrate the efficacy of psychoeducation group treatment for BED and EDNOS patients.

Abstract
Given the increasing frequency of obesity and related maladaptive eating patterns in pediatric populations, health care professionals in a variety of settings must find ways to treat persons who are obese and have maladaptive eating patterns. The authors summarized literature related to binge eating disorder, boredom eating, emotional eating, and night eating syndrome and developed educational handouts designed for children/adolescents and their families who present with these eating problems. These educational handouts may be used by primary care physicians, psychologists, psychiatrists, nurses, and other specialists in medical settings. They are free for use in educational purposes, with permission from the authors, but are not intended to replace appropriate health care and follow-up.

Abstract
Binge Eating Disorder (BED), a chronic condition characterized by eating disorder psychopathology and physical and social disability, represents a significant public health problem. Guided Self Help (GSH) treatments for BED appear promising and may be more readily disseminable to mental health care providers, accessible to patients, and cost-effective than existing, efficacious BED specialty treatments which are limited in public health utility and impact given their time and expense demands. No existing BED GSH treatment has incorporated affect regulation models of binge eating, which appears warranted given research linking negative affect and binge eating. Integrative Response Therapy (IRT), a new group-based guided self-help treatment, based on the affect regulation model of binge eating, that has shown initial promise in a pilot sample of adults meeting DSM IV criteria for BED, is described. Fifty-four% and 67% of participants were abstinent at post-treatment and three month follow-up respectively. There was a significant reduction in the number of binge days over the previous 28 days from baseline to post-treatment [14.44 (±7.16) to 3.15 (±5.70); t=7.71, p<.001; d=2.2] and from baseline to follow-up [14.44 (±7.16) to 1.50 (±2.88); t=5.64, p<.001; d=1.7]. All subscales from both the Eating Disorder Examination - Questionnaire and Emotional Eating Scale were significantly lower at post-treatment compared to baseline. 100% of IRT participants would recommend the program to a friend or family member in need. IRT's longer-term efficacy and acceptability are presently being tested in a National Institute of Mental Health funded randomized controlled trial.

Abstract
Background Binge eating disorder (BED) is a prevalent clinical eating disorder associated with increased psychopathology, psychiatric comorbidity, overweight and obesity, and increased health care costs. Since its inclusion in the DSM-IV, a few randomized controlled trials (RCTs) have suggested efficacy of book-based self-help interventions in the treatment of this disorder. However, evidence from larger RCTs is needed. Delivery of self-help through new technologies such as the internet should be investigated in particular, as these approaches have the potential to be more interactive and thus more attractive to patients than book-based approaches. This study will evaluate the efficacy of an internet-based guided self-help program (GSH-I) and cognitive-behavioral therapy (CBT), which has been proven in several studies to be the gold standard treatment for BED, in a prospective multicenter randomized trial. Methods The study assumes the noninferiority of GSH-I compared to CBT. Both treatments lasted 4 months, and maintenance of outcome will be assessed 6 and 18 months after the end of treatment. A total of 175 patients with BED and a body mass index between 27 and 40 kg/m2 were randomized at 7 centers in Germany and Switzerland. A 20% attrition rate was assumed. As in most BED treatment trials, the difference in the number of binge eating days over the past 28 days is the primary outcome variable. Secondary outcome measures include the specific eating disorder psychopathology, general psychopathology, body weight, quality of life, and self-esteem. Predictors and moderators of treatment outcome will be determined, and the cost-effectiveness of both treatment conditions will be evaluated. Results The methodology for the INTERBED study has been detailed. Conclusions Although there is evidence that CBT is the first-line treatment for BED, it is not widely available. As BED is still a recent diagnostic category, many cases likely remain undiagnosed, and a large number of patients either receive delayed treatment or never get adequate treatment. A multicenter efficacy trial will give insight into the efficacy of a new internet-based guided self-help program and will allow a direct comparison to the evidence-based gold standard treatment of CBT in Germany.

Abstract
Eating disorders are a common mental disorder during adolescence and young adulthood. While prevalence rates of eating disorders dramatically increased during the second half of the last century, these rates have remained relatively stable over the last 20 years. According to ICD-10 eating disorders are diagnostically categorized as anorexia nervosa, bulimia nervosa and atypical eating disorders or eating disorders not otherwise specified. Concerning the etiology, genetic factors are involved, especially in anorexia nervosa, as well as psychological and sociocultural factors. Evidence-based recommendations are available for the treatment of bulimia nervosa and binge eating disorder and in this context cognitive behavioral therapy is seen as the first choice. In contrast, the state of knowledge concerning the treatment of anorexia nervosa is still limited, especially concerning effective treatments for adults. Recent data only provide evidence for the effectiveness of family therapy for adolescents. Due to the lack of high quality studies, research on therapy for anorexia nervosa is a future challenge.

Abstract
Binge eating disorder (BED) is the most prevalent eating disorder in adults, and individuals with BED report greater general and specific psychopathology than non-eating disordered individuals. The current paper reviews research on psychological treatments for BED, including the rationale and empirical support for cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPT), dialectical behavior therapy (DBT), behavioral weight loss (BWL), and other treatments warranting further study. Research supports the effectiveness of CBT and IPT for the treatment of BED, particularly for those with higher eating disorder and general psychopathology. Guided self-help CBT has shown efficacy for BED without additional pathology. DBT has shown some promise as a treatment for BED, but requires further study to determine its long-term efficacy. Predictors and moderators of treatment response, such as weight and shape concerns, are highlighted and a stepped-care model proposed. Future directions include expanding the adoption of efficacious treatments in clinical practice, testing adapted treatments in diverse samples (e.g., minorities and youth), improving treatment outcomes for nonresponders, and developing efficient and cost-effective stepped-care models.

Abstract
OBJECTIVE An important question in implementation/dissemination research is whether the efficacy of a given treatment varies in part based on the therapist delivering the treatment. This study sought to provide practical guidance to researchers in the field of eating disorders for building measurement of therapist effects into the design of a typical, relatively small randomized controlled trial (RCT). METHOD Using assumptions based on past trials of eating disorder treatments, Monte Carlo simulations were used to examine 12 different scenarios based on crossing the number of therapists (between two and five) and the estimated therapist effect size (small, medium, and large). Patient sample size and study design were held constant. RESULTS There was reasonable power (≥70%) to detect the therapist effect with three or four therapists and a large effect size. DISCUSSION Several practical implications for testing therapist effects in RCT are discussed.

Abstract
Eating disorders are a significant source of psychiatric morbidity in young women and demonstrate high comorbidity with mood, anxiety, and substance use disorders. Thus, clinicians may encounter eating disorders in the context of treating other conditions. This review summarizes the efficacy of current and emerging treatments for anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Treatment trials were identified using electronic and manual searches and by reviewing abstracts from conference proceedings. Family based therapy has demonstrated superiority for adolescents with AN but no treatment has established superiority for adults. For BN, both 60 mg fluoxetine and cognitive behavioral therapy (CBT) have well-established efficacy. For BED, selective serotonin reuptake inhibitors, CBT, and interpersonal psychotherapy have demonstrated efficacy. Emerging directions for AN include investigation of the antipsychotic olanzapine and several novel psychosocial treatments. Future directions for BN and BED include increasing CBT disseminability, targeting affect regulation, and individualized stepped-care approaches.

Abstract
The link between negative affect and binge eating in those with binge eating disorder (BED) has been well established. The present study examined the efficacy of a treatment for BED designed to increase recognition and regulation of negative emotion, replicating and extending a previous investigation (Clyne, C., & Blampied, N.M. [2004]. Training in emotion regulation as a treatment for binge eating: A preliminary study. Behaviour Change, 21, 269-281) by including a control group, a larger number of participants, and formal diagnoses rather than classifying binge eating symptomatology from self-report questionnaires. Twenty-three women diagnosed with subthreshold or full syndrome BED (using the Eating Disorders Examination) participated in a treatment program that focused on increasing emotional regulation skills. Each participant completed the Eating Disorders Examination Questionnaire, the Binge Eating Scale, the Emotional Eating Scale, and completed self-monitoring records of binge episodes. Binge abstinence rates following treatment (post-treatment and 1 year follow-up were 78% and 87% respectively) were comparable to other empirically supported treatments for BED. Other positive changes in eating and general pathology were observed. These effects were well-maintained up to 1 year later.

Abstract
OBJECTIVE Two quasi-experimental pilot studies examined eating pathology, eating self-efficacy, shame, guilt, and pride in adults with chronic illness before and after participating in brief cognitive-behavioral psychoeducational groups addressing eating concerns. METHOD In Study 1, 60 adults completed assessments before and after a series of two groups; in Study 2, 21 adults also completed an assessment five weeks prior to the first group to identify time-related changes in symptoms. RESULTS Study 1 participants improved across domains, whereas Study 2 analyses also examining time-related changes showed improvements in eating self-efficacy, shame, guilt, and pride, but not in eating pathology. DISCUSSION Psychoeducational groups may help improve symptoms including eating pathology, eating self-efficacy, shame, guilt, and pride among chronically-ill adults with eating concerns.

Abstract
OBJECTIVE The aim of this study was to compute and compare mean effects of various treatments for binge eating disorder. METHOD A total of 38 studies with 1973 participants fulfilled the defined inclusion criteria. Effect sizes, odds ratios, and simple rates were integrated in fixed and random (mixed) effects categorical models. RESULTS From randomized controlled trials, psychotherapy and structured self-help, both based on cognitive behavioral interventions, were found to have large effects on the reduction of binge eating. Regarding pharmacotherapy, mainly comprising antidepressants, randomized controlled trials revealed medium effects for the reduction of binge eating. Uncontrolled studies on weight-loss treatments demonstrated moderate reductions of binge eating. Combination treatments did not result in higher effects compared with single-treatment regimens. Except for weight-loss treatment, none of the interventions resulted in a considerable weight reduction. DISCUSSION Psychotherapy and structured self-help, both based on cognitive-behavioral interventions, should be recommended as the first-line treatments.

Abstract
OBJECTIVE The purpose of this investigation was to examine differences in personality dimensions among individuals with bulimia nervosa, binge eating disorder, non-binge eating obesity, and a normal-weight comparison group as well as to determine the extent to which these differences were independent of self-reported depressive symptoms. METHOD Personality dimensions were assessed using the Multidimensional Personality Questionnaire in 36 patients with bulimia nervosa, 54 patients with binge eating disorder, 30 obese individuals who did not binge eat, and 77 normal-weight comparison participants. RESULTS Participants with bulimia nervosa reported higher scores on measures of stress reaction and negative emotionality compared to the other 3 groups and lower well-being scores compared to the normal-weight comparison and the obese samples. Patients with binge eating disorder scored lower on well-being and higher on harm avoidance than the normal-weight comparison group. In addition, the bulimia nervosa and binge eating disorder groups scored lower than the normal-weight group on positive emotionality. When personality dimensions were reanalyzed using depression as a covariate, only stress reaction remained higher in the bulimia nervosa group compared to the other 3 groups and harm avoidance remained higher in the binge eating disorder than the normal-weight comparison group. CONCLUSIONS The higher levels of stress reaction in the bulimia nervosa sample and harm avoidance in the binge eating disorder sample after controlling for depression indicate that these personality dimensions are potentially important in the etiology, maintenance, and treatment of these eating disorders. Although the extent to which observed group differences in well-being, positive emotionality, and negative emotionality reflect personality traits, mood disorders, or both, is unclear, these features clearly warrant further examination in understanding and treating bulimia nervosa and binge eating disorder.

Abstract
OBJECTIVE The purpose of this investigation was to compare three types of treatment for binge eating disorder to determine the relative efficacy of self-help group treatment compared to therapist-led and therapist-assisted group cognitive-behavioral therapy. METHOD A total of 259 adults diagnosed with binge eating disorder were randomly assigned to 20 weeks of therapist-led, therapist-assisted, or self-help group treatment or a waiting list condition. Binge eating as measured by the Eating Disorder Examination was assessed at baseline, at end of treatment, and at 6 and 12 months, and outcome was assessed using logistic regression and analysis of covariance (intent-to-treat). RESULTS At end of treatment, the therapist-led (51.7%) and the therapist-assisted (33.3%) conditions had higher binge eating abstinence rates than the self-help (17.9%) and waiting list (10.1%) conditions. However, no between-group differences in abstinence rates were observed at either of the follow-up assessments. The therapist-led condition also showed more reductions in binge eating at end of treatment and follow-up assessments compared to the self-help condition, and treatment or waiting period completion rates were higher in the therapist-led (88.3%) and waiting list (81.2%) conditions than in the therapist-assisted (68.3%) and self-help (59.7%) conditions. CONCLUSIONS Therapist-led group cognitive-behavioral treatment for binge eating disorder led to higher binge eating abstinence rates, greater reductions in binge eating frequency, and lower attrition compared to group self-help treatment. Although these findings indicate that therapist delivery of group treatment is associated with better short-term outcome and less attrition than self-help treatment, the lack of group differences at follow-up suggests that self-help group treatment may be a viable alternative to therapist-led interventions.

Abstract
BACKGROUND A specific manual-based form of cognitive behavioural therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN) and other common related syndromes such as binge eating disorder. Other psychotherapies and modifications of CBT are also used. OBJECTIVES To evaluate the efficacy of CBT, CBT-BN and other psychotherapies in the treatment of adults with bulimia nervosa or related syndromes of recurrent binge eating. SEARCH STRATEGY Handsearch of The International Journal of Eating Disorders since first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PsycInfo, CURRENT CONTENTS, LILACS, SCISEARCH, CENTRAL and the The Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register; citation list searching and personal approaches to authors were used. Search date June 2007. SELECTION CRITERIA Randomised controlled trials of psychotherapy for adults with bulimia nervosa, binge eating disorder and/or eating disorder not otherwise specified (EDNOS) of a bulimic type which applied a standardised outcome methodology and had less than 50% drop-out rate. DATA COLLECTION AND ANALYSIS Data were analysed using the Review Manager software program. Relative risks were calculated for binary outcome data. Standardised mean differences were calculated for continuous variable outcome data. A random effects model was applied. MAIN RESULTS 48 studies (n = 3054 participants) were included. The review supported the efficacy of CBT and particularly CBT-BN in the treatment of people with bulimia nervosa and also (but less strongly due to the small number of trials) related eating disorder syndromes.Other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term. Self-help approaches that used highly structured CBT treatment manuals were promising. Exposure and Response Prevention did not enhance the efficacy of CBT.Psychotherapy alone is unlikely to reduce or change body weight in people with bulimia nervosa or similar eating disorders. AUTHORS' CONCLUSIONS There is a small body of evidence for the efficacy of CBT in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More and larger trials are needed, particularly for binge eating disorder and other EDNOS syndromes. There is a need to develop more efficacious therapies for those with both a weight and an eating disorder.

Abstract
Resources that summarize research-supported treatments (RSTs) are useful tools in clinical decision making. These resources can be particularly helpful when clinicians are uncertain about which treatment direction to take, when treatment does not seem to be working, when clinicians need to justify their approach to others, and when clinicians do not have time to review recent research on a particular clinical issue. This article describes resources for finding short, user-friendly summaries of research-supported group treatments, briefly describes several research-supported group treatments that are not well described in existing resources, and recommends several ways in which these research summaries can be used to improve group practice.

Abstract
This paper reviews investigations of psychotherapy outcome studies for binge eating disorder, which has recently been intensively studied as several researchers have undertaken the task of delineating which treatment options are the most effective. Several randomized, controlled clinical trials have provided important findings. A current debate concerns what the initial course of treatment should be, reducing binge eating patterns or reducing weight. Several limitations to this literature are mentioned, including the dearth of studies investigating treatment for men and boys with binge eating disorder.

Abstract
OBJECTIVE Cognitive behavioral therapy (CBT) is efficacious for the treatment of bulimia nervosa (BN) and binge-eating disorder (BED). As a number of factors limit the availability of CBT, self-help manuals have been developed to make the treatment more widely available. METHOD Published studies evaluating the efficacy of self-help programs in the treatment of BN and BED were reviewed. RESULTS Controlled studies of self-help programs for BN and BED have often employed a waiting list control group, and indicate that self-help provides more benefit than remaining on a waiting list. However, fewer studies have utilized a more active control group, and these studies have not been as positive. CONCLUSION In general, open and wait-list trials indicate that self-help is helpful in treating BN and BED, but there is little evidence for the specific efficacy of self-help in comparison to other treatments. Additional studies of self-help are needed to determine the specific utility of self-help interventions for BN and BED.

Abstract
OBJECTIVE The Research Triangle Institute-University of North Carolina Evidence Based Practice Center (RTI-EPC) systematically reviewed evidence on efficacy of treatment for binge eating disorder (BED), harms associated with treatments, factors associated with treatment efficacy, and differential outcome by sociodemographic characteristics. METHOD We searched six major databases for studies on the treatment of BED published from 1980 to September, 2005, in all languages against a priori inclusion/exclusion criteria and focused on eating, psychiatric or psychological, or biomarker outcomes. RESULTS Twenty-six studies, including medication-only, medication plus behavioral intervention, and behavioral intervention only designs, met inclusion criteria. The strength of the evidence for medication and behavioral interventions was moderate, for self-help and other interventions was weak, for treatment-related harms was strong, for factors associated with efficacy of treatment was weak, and for differential outcome by sociodemographic factors was nonexistent. Individual or group CBT reduces binge eating and improves abstinence rates for up to 4 months after treatment but does not lead to weight loss. Medications may play a role in treating BED patients. CONCLUSION The literature regarding treatment efficacy for BED is variable. Future directions include the identification of optimal interventions that are associated with both sustained abstinence from binge eating and permanent weight loss.

Abstract
The present study investigated the efficacy of self-help based on cognitive behaviour therapy in combination with Internet support in the treatment of bulimia nervosa and binge eating disorder. After confirming the diagnosis with an in-person interview, 73 patients were randomly allocated to treatment or a waiting list control group. Treated individuals showed marked improvement after 12 weeks of self-help compared to the control group on both primary and secondary outcome measures. Intent-to-treat analyses revealed that 37% (46% among completers) had no binge eating or purging at the end of the treatment and a considerable number of patients achieved clinically significant improvement on most of the other measures as well. The results were maintained at the 6-month follow-up, and provide evidence to support the continued use and development of self-help programmes.

Abstract
We compared preliminary feasibility and acceptability of CD-ROM-delivered CBT for overweight individuals with binge-eating disorder (BED) to 10 weekly group CBT sessions (Group) and to a waiting list control (WL). Attrition was numerically greater in the Group than the CD-ROM condition; although only Group differed significantly from WL in dropout rates. Those in the CD-ROM condition reported continued use of their CD-ROM after treatment. Also, the majority of WL participants elected to receive CD-ROM over Group treatment at the end of the waiting period. Preliminarily, no significant differences emerged across the active treatment groups on most outcome measures. However, there was a significantly greater decline in binge days in the two active groups relative to WL. CD-ROM appears to be an acceptable and at least initially preferred method of CBT delivery for overweight individuals with BED.

Abstract
The aim of the study was to assess the efficacy of a 12-week CBT-based pure and guided self-help among 29 patients with full and subthreshold bulimia nervosa, and binge eating disorder. In the intention-to-treat analyses, self-help had a moderately positive and sustained effect on the patients' eating problems. The patients reduced their mean number of objective bulimic episodes and purging behavior by 26% and 22% over the course of treatment. The corresponding reduction levels for the treatment completers (n=21) were 41% and 34%, respectively. As in the previous study, there were no significant differences between the pure and guided self-help mode in terms of outcome, and the results were sustained 6 months after the end of the treatment. The findings are discussed in relation to the shorter duration of the self-help, the lower rate of attrition, and the characteristics of the sample compared to the earlier trial.

Abstract
BACKGROUND Anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS) are common and disabling disorders. Many patients experience difficulties accessing specialist psychological treatments. Pure self-help (PSH: self-help material only) or guided self-help (GSH: self-help material with therapist guidance), may bridge this gap. MAIN OBJECTIVE Evaluate evidence from randomised controlled trials (RCTs) / controlled clinical trials (CCTs) for the efficacy of PSH/GSH with respect to eating disorder symptoms, compared with waiting list or placebo/attention control, other psychological or pharmacological treatments (or combinations/augmentations) in people with eating disorders. SECONDARY OBJECTIVE Evaluate evidence for the efficacy of PSH/GSH regarding comorbid symptomatology and costs. SEARCH STRATEGY CCDANCTR-Studies and CCDANCTR-References were searched in November 2005, other electronic databases were searched, relevant journals and grey literature were checked, and personal approaches were made to authors. SELECTION CRITERIA Published/unpublished RCTs/CCTs evaluating PSH/GSH for any eating disorder. DATA COLLECTION AND ANALYSIS Data was extracted using a customized spreadsheet. Relative Risks (RR) were calculated from dichotomous data and weighted/standardized mean differences (WMD/SMD) from continuous data, using a random effects model. MAIN RESULTS Twelve RCTs and three CCTs were identified, all focusing on BN, BED, EDNOS or combinations of these, in adults, using manual-based PSH/GSH across various settings. Primary comparisons:At end of treatment, PSH/GSH did not significantly differ from waiting list in abstinence from bingeing (RR 0.72, 95% CI 0.47 to 1.09), or purging (RR 0.86, 95% CI 0.68 to 1.08), although these treatments produced greater improvement on other eating disorder symptoms, psychiatric symptomatology and interpersonal functioning but not depression. Compared to other formal psychological therapies, PSH/GSH did not differ significantly at end of treatment or follow-up in improvement on bingeing and purging (RR 0.99, 95% CI 0.75 to 1.31), other eating disorder symptoms, level of interpersonal functioning or depression. There were no significant differences in treatment dropout. Secondary comparisons:One small study in BED found that cognitive-behavioural GSH compared to a non-specific control treatment produced significantly greater improvements in abstinence from bingeing and other eating disorder symptoms. Studies comparing PSH with GSH found no significant differences between treatment groups at end of treatment or follow-up. Comparison between different types of PSH/GSH found significant differences on eating disorder symptoms but not on bingeing/purging abstinence rates. AUTHORS' CONCLUSIONS PSH/GSH may have some utility as a first step in treatment and may have potential as an alternative to formal therapist-delivered psychological therapy. Future research should focus on producing large well-conducted studies of self-help treatments in eating disorders including health economic evaluations, different types and modes of delivering self-help (e.g. computerised versus manual-based) and different populations and settings.

Abstract
Survey research is demonstrating that binge eating and compulsive eating may be a significant problem in the obese population. There is higher incidence of binge eating among women, associated with subjective distress and poor prognosis for weight control. Despite attendant health risks, researched clinical responses have not been developed. A before and after uncontrolled pilot study aimed to evaluate the effectiveness of group therapy for women who binge eat and compulsively eat. Participants attended a weekly integrative therapy group for 6 months. Measurements before and after the group intervention were taken using the Binge Eating Scale and Clinical Outcomes in Routine Evaluation inventories. Before and after interviews were thematically analysed for changes in eating behaviour. Following the group intervention, all participants demonstrated changes in eating behaviour measured by the Binge Eating Scale, the overall effect from baseline to 1 year demonstrates statistical significance. Qualitative data revealed four categories that underpinned reduction in binge eating: changes in dichotomous thinking, awareness of eating behaviour, detachment from food and dietary changes. An integrative model of group therapy warrants further research and refinement for this population, a group protocol for nurses working in the field of obesity and eating disorders could be developed.

Abstract
OBJECTIVE To evaluate self-help interventions for patients with binge eating disorder (BED) and bulimia nervosa (BN), tested in randomized controlled trials, and compared with waiting list or any other type of control group. METHODS A systematic review including quality appraisal was conducted of randomized controlled trials, using self-help techniques in patients with BED and/or BN. Six databases were searched during the period between January 1994 and June 2004. RESULTS A total of 2686 articles were identified, 1701 abstracts were evaluated in detail and, nine studies fulfilled the inclusion criteria for this review. All studies indicated that patients treated with active interventions had a reduced number of binge eating episodes at end of treatment. CONCLUSION The results support self-help interventions but shall be interpreted with caution. Because of the small number of studies using self-help techniques for BED and BN, further larger randomized, multi-center controlled studies that apply standardized inclusion criteria, evaluation instruments and self-help materials, are needed.

Abstract
OBJECTIVE This investigation sought to identify subtypes of binge eating disorder (BED) based on history of mood disorder (MOOD) and substance use disorder (SUD). METHOD Eighty-four women who met criteria for BED were administered semistructured interviews and completed self-report questionnaires assessing eating pathology, depressive symptoms, self-esteem, body dissatisfaction, and personality traits. RESULTS Thirty-nine participants (46.4%) had a lifetime history of a SUD and 60 (71.4%) had a lifetime history of a MOOD. The SUD subtype was associated with a greater impulsivity and frequency of binge eating episodes compared with the no SUD subtype. The MOOD subtype participants reported greater distress, more psychopathology, less dietary restraint, lower self-esteem, more frequent binge eating, higher levels of negative affect, and more frequent trauma and abuse history than the no MOOD subtype. DISCUSSION The results of this study indicate that subtypes of BED on the basis of MOOD and SUD may be associated with a more severe variant of the disorder.

Abstract
BACKGROUND Cognitive behavioral therapy (CBT) has efficacy for binge eating disorder (BED) but not obesity. No controlled studies have tested whether adding obesity medication to CBT facilitates weight loss. We performed a randomized, placebo-controlled study of orlistat administered with guided self-help CBT (CBTgsh). METHODS Fifty obese BED patients were randomly assigned to 12-week treatments of either orlistat plus CBTgsh (120 mg three times a day [t.i.d.]) or placebo plus CBTgsh and were followed in double-blind fashion for 3 months after treatment. RESULTS Seventy-eight percent of patients completed treatments without differential dropout between orlistat+CBTgsh and placebo+CBTgsh. Intent-to-treat remission rates (zero binges for past 28 days on Eating Disorder Examination Interview) were significantly higher for orlistat+CBTgsh than placebo+CBTgsh (64% versus 36%) at posttreatment but not at 3-month follow-up (52% in both). Intent-to-treat rates for achieving 5% weight loss were significantly higher for orlistat+CBTgsh than placebo+CBTgsh at posttreatment (36% versus 8%) and 3-month follow-up (32% versus 8%). Significant and comparable improvements in eating disorder psychopathology and psychological distress occurred in both treatments. CONCLUSIONS The addition of orlistat to CBTgsh was associated with greater weight loss than the addition of placebo to CBTgsh. Clinical improvements were generally maintained at 3-month follow-up after treatment discontinuation.

Abstract
Manual-based cognitive behavior therapy (CBT) is presently the most effective treatment of bulimia nervosa. Its efficacy is limited, however. Different strategies for improving upon current manual-based CBT are discussed, including combining CBT with antidepressant medication, integrating CBT with alternative psychological therapies, and expanding the scope and flexibility of manual-based CBT. CBT is underutilized in clinical practice. Dissemination of evidence-based treatment is a priority. Research on anorexia nervosa is minimal. Effective treatments have yet to be developed, although the Maudsley method of family therapy has shown the most promise in the treatment of adolescents. The most commonly seen eating disorders in clinical practice are those classified as "eating disorder not otherwise specified." With the exception of binge eating disorder (BED), however, they have been neglected by researchers. Several psychological therapies have been shown to be effective in treating BED. Controversy exists over whether treatment-specific effects have been identified. Whereas treatments have proved effective in eliminating binge eating and associated eating disorder psychopathology, achieving clinically significant weight loss remains a challenge.

Abstract
This study's purpose was to examine the extent to which participants (N = 143) receiving cognitive-behavioral therapy for bulimia nervosa (BN) reported implementing therapeutic strategies to abstain from BN behaviors, and to assess whether use of specific strategies predicts outcome at treatment end and 1- and 6-month follow-up. Frequency of outcome expectancies (OE), stimulus-response prevention (SRP), and social support-seeking (SSS) strategies significantly increased by end of treatment. By 1-month follow-up, use of SSS, not OE or SRP, declined significantly relative to treatment end. Although frequency of coping strategy use at treatment end did not predict 1-month BN symptom remission, SSS use at 1-month follow-up predicted 6-month remission. Findings highlight the importance of social support to maintain treatment gains.
