Abstract
OBJECTIVE Peer support has been shown to support personal recovery from mental illness. It is unclear whether the effects of peer support across different mental illnesses depend on the organizational setting. The authors reviewed the effectiveness of peer support for both personal recovery and clinical recovery of adults with any mental illness and evaluated the effectiveness of peer support in different settings. METHODS A systematic review of randomized controlled trials (RCTs) was conducted in PubMed, PsycInfo, CINAHL, Cochrane Library, and Web of Science. A meta-analysis of outcomes of personal and clinical recoveries at the end of interventions was conducted. RESULTS In total, 49 RCTs with 12,477 participants with any mental illness were included. Most of the trials had a high risk for bias. Results of the meta-analysis indicated that peer support in general had a small positive effect on personal recovery (standard mean difference [SMD]=0.20; 95% CI=0.11-0.29) and decreased anxiety symptoms (SMD=-0.21; 95% CI=-0.40 to -0.02), with most trials evaluating peers added to mental health-related hospital services. No data for peers in established service roles were available for the meta-analysis. Peer-designed interventions developed to be provided independently of hospital services and delivered in community settings had a modest effect on self-advocacy. A small nonsignificant effect on personal recovery for peer support delivered online was also observed. CONCLUSIONS The effect on personal recovery from mental illness was most evident in peer support added to hospital services. High-quality RCTs with comparable cocreated interventions and clear descriptions of mechanisms of change are needed to further investigate peer support efficacy.

Int J Eat Disord 2022; 55:1521-1531. [PMID: 36054766 DOI: 10.1002/eat.23804] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/10/2022] [Accepted: 08/10/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND Loss-of-control (LOC)-eating postoperatively predicts suboptimal longer-term outcomes following bariatric surgery. This study examined longer-term effects through 24-month follow-ups after completing treatments in a randomized controlled trial testing guided-self-help treatments (cognitive-behavioral therapy [gshCBT] and behavioral weight-loss [gshBWL]) and control (CON) delivered postoperatively for LOC-eating. METHODS 140 patients with LOC-eating 6 months after bariatric surgery were randomized (5:5:2 ratio) to 3-months of gshCBT (n = 56), gshBWL (n = 60), or CON (n = 24) delivered by trained allied-health clinicians. Independent assessments were performed throughout/after treatments and at 6-, 12-, 18-, and 24-month follow-ups; 83% of patients were assessed at 24-month follow-up. RESULTS Intention-to-treat analyses comparing the three groups (gshCBT vs. gshBWL vs. CON) in LOC-eating abstinence at posttreatment (30%, 27%, 38%), 12-month follow-up (34%, 32%, 42%), and 24-month follow-up (45%, 32%, 38%) revealed no significant differences. Mixed-models revealed significantly reduced LOC-eating frequency through posttreatment, no significant changes in LOC-eating frequency during follow-up, and no differences between the three groups. Weight reduced significantly, albeit modestly, through posttreatment but increased significantly and substantially during follow-ups, with no differences between groups. CONCLUSIONS Overall, the 12-week scalable guided-self-help treatments did not differ from each other or control, were associated with significantly reduced frequency of LOC-eating and modest weight loss at posttreatment but were followed by significant weight gain during the 24-month follow-up. Weight gain was substantial and nearly universal whereas the frequency of LOC-eating did not change over time (i.e., LOC-eating reductions and abstinence rates were well maintained through 24-moth follow-ups). Patients with postoperative LOC-eating require more intensive adjunctive treatments. PUBLIC SIGNIFICANCE Loss-of-control (LOC) eating postoperatively predicts poorer bariatric surgery outcomes and the longer-term effects of postoperative adjunctive postoperative interventions for LOC eating are unknown. In this 24-month follow-up of a controlled study of scalable guided-self-help treatments and a control condition, improvements in LOC-eating frequency, eating-disorder psychopathology, and depression during treatment were maintained well, with no differences between the three groups. Proportion of patients achieving abstinence from LOC-eating at the 24-month follow-up ranged from 38% to 45% across the three groups. In contrast, weight increased significantly during the 24-month follow-ups, with no differences between the three groups. Findings suggest LOC-eating following bariatric surgery might represent a "marker" for a subgroup of patients that are at risk for substantial weight gains over time. LOC eating following bariatric surgery is challenging to treat with low-intensity scalable treatments and may require more intensive specialist treatments.

Int J Eat Disord 2022; 55:902-913. [PMID: 35665526 PMCID: PMC9328197 DOI: 10.1002/eat.23750] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 04/29/2022] [Accepted: 04/30/2022] [Indexed: 12/03/2022]
Abstract
OBJECTIVE To evaluate whether the results of a quasi-randomized study, comparing dialectical behavior therapy for binge-eating disorder (DBT-BED) and an intensive, outpatient cognitive behavior therapy (CBT+) in individuals with BED, would be replicated in a nonrandomized study with patients who more closely resemble everyday clinical practice. METHOD Patients with (subthreshold) BED (N = 175) started one of two group treatments: DBT-BED (n = 42) or CBT+ (n = 133), at a community eating disorder service. Measures of eating disorder pathology, emotion regulation, and general psychopathology were examined at end of treatment (EOT) and at 6-month follow-up using generalized linear models with multiple imputation. RESULTS Both treatments lead to substantial decreases on primary and secondary measures. Statistically significant, medium-size differences between groups were limited to global eating disorder psychopathology (d = -.62; 95% CI = .231, .949) at EOT and depressive symptoms at follow-up (d = -.45; 95% CI = .149, 6.965), favoring CBT+. Dropout of treatment included 15.0% from CBT+ and 19.0% from DBT-BED (difference nonsignificant). DISCUSSION Decreases in global eating disorder psychopathology were achieved faster with CBT+. Overall, improvements in DBT-BED were comparable to those observed in CBT+. Findings of the original trial, favoring CBT+ on the number of OBE episodes, emotional dysregulation and self-esteem at EOT, and on eating disorder psychopathology and self-esteem at follow-up, were not replicated. With similar rates of treatment dropout and about half of the therapy time used in CBT+, DBT-BED can be considered a relevant treatment for BED in everyday clinical practice. PUBLIC SIGNIFICANCE In this effectiveness study, dialectical behavior therapy (DBT) resulted in clinically relevant improvements in individuals with binge eating disorder. Changes were broadly comparable to those of cognitive behavior therapy (CBT), the current treatment of choice. Although CBT resulted in decreases in eating disorder psychopathology faster, there was a trend toward relapse in CBT at 6-month follow-up. Therefore, the less costly DBT-program can be considered a relevant treatment in clinical practice.

Abstract
OBJECTIVE Cognitive-behavioral therapy (CBT)-therapist-led (CBTth) and guided-self-help (CBTgsh)-has efficacy for binge-eating disorder (BED) but many patients do not benefit sufficiently. We examined predictors and moderators for these two CBT methods. METHOD Data were aggregated from randomized controlled trials (RCTs) testing psychosocial treatments for BED in the U.S. Predictors and moderators of outcomes (treatment completion and binge-eating remission) were examined in N = 457 participants who received either CBTgsh (N = 164) or CBTth (N = 293). RESULTS Analyses, adjusting for demographic/clinical variables, indicated CBTth was significantly superior to CBTgsh for treatment completion (odds ratio [OR] = 20.0) and remission (OR = 14.6). For remission, analyses revealed significant predictors (age, treatment length, Weight Concern), a moderator (weight concern [OR = 5.13]), and a significant interaction between CBT-type and treatment length (OR = 2.66). For CBTgsh, longer treatment was associated with less remission, whereas for CBTth, longer treatment was associated with greater remission. For CBTgsh, 44.1% with low weight concern versus 56.3% with high weight concern achieved remission whereas for CBTth, 43.5% with high weight concern and 61.0% with low weight concern achieved remission. DISCUSSION Analyses of aggregated RCT BED data, adjusting for demographic/clinical characteristics, indicated superiority (large effect-sizes) in treatment outcomes of CBTth over CBTgsh and that Weight Concern moderated outcomes.

Abstract
OBJECTIVE Loss-of-control (LOC) eating postoperatively is a consistent predictor of suboptimal longer-term bariatric surgery outcomes. This randomized controlled trial examined the effectiveness of two guided self-help treatments (cognitive behavioral therapy [gshCBT] and behavioral weight loss [gshBWL]) compared with a control (CON) for reducing LOC eating and weight. METHODS A total of 140 patients with recurrent LOC eating approximately 6 months after bariatric surgery were randomly assigned (5:5:2 ratio) to one of three conditions: gshCBT (n = 56), gshBWL (n = 60), or CON (n = 24). Three-month treatments were delivered by trained allied health clinicians to increase generalizability to bariatric surgery settings. Independent assessments were performed by doctoral research-clinicians using established interviews/measures; posttreatment outcomes were obtained for 89% of patients. RESULTS Mixed models revealed significant improvements for LOC eating frequency and weight loss but no significant differences between treatments; race neither predicted (main effect) nor moderated (interaction effect) treatment outcomes. Intent-to-treat categorical analyses of abstinence from LOC eating (30% for gshCBT, 27% for gshBWL, 38% for CON) and proportion attaining 5% weight loss (20%, 22%, 17%) revealed no significant differences between treatments; non-White participants had a higher proportion achieving LOC eating abstinence but a lower proportion attaining 5% weight loss compared with White participants. CONCLUSIONS In this 12-week randomized controlled trial following bariatric surgery, significant LOC eating reductions and weight loss did not differ significantly between treatments. Race was associated with posttreatment categorical outcomes.

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.

Abstract
PURPOSE A common challenge among a subgroup of individuals with obesity is binge eating, that exists on a continuum from mild binge eating episodes to severe binge eating disorder (BED). BED is common among bariatric patients and the prevalence of disordered eating and ED in bariatric surgery populations is well known. Conventional treatments and assessment of obesity seldom address the underlying psychological mechanisms of binge eating and subsequent obesity. This study, titled PnP (People need People) is a psychoeducational group pilot intervention for individuals with BED and obesity including patients with previous bariatric surgery. Design, feasibility, and a broad description of the study population is reported. MATERIAL AND METHODS A total of 42 patients were from an obesity clinic referred to assessment and treatment with PnP in a psychoeducational group setting (3-hour weekly meetings for 10 weeks). Of these, 6 (14.3%) patients had a previous history of bariatric surgery. Feasibility was assessed by tracking attendance, potentially adverse effects and outcome measures including body mass index (BMI), eating disorder pathology, overvaluation of shape and weight, impairment, self-reported childhood difficulties, alexithymia, internalized shame as well as health related quality of life (HRQoL). RESULTS All 42 patients completed the intervention, with no adverse effects and a high attendance rate with a median attendance of 10 sessions, 95% CI (8.9,9.6) and 0% attrition. Extent of psychosocial impairment due to eating disorder pathology, body dissatisfaction and severity of ED symptoms were high among the patients at baseline. Additionally, self-reported childhood difficulties, alexithymia, and internalized shame were high among the patients and indicate a need to address underlying psychological mechanisms in individuals with BED and comorbid obesity. Improvement of HRQoL and reduction of binge eating between baseline and the end of the intervention was observed with a medium effect. CONCLUSION This feasibility study supports PnP as a potential group psychoeducational intervention for patients living with BED and comorbid obesity. Assessments of BED and delivery of this intervention may optimize selection of candidates and bariatric outcomes. These preliminary results warrant further investigation via a randomized control trial (RCT) to examine the efficacy and effectiveness of PnP.

Abstract
OBJECTIVE The Criterion B binge-eating symptoms represent five symptoms associated with binge eating. Any three out of five symptoms can be used to meet Criterion B. However, Criterion B symptoms may not be interchangeable in terms of how binge-eating severity is associated with each symptom. Item response theory (IRT) can test how endorsing each symptom relates to the overall level (i.e., severity) of binge-eating measured by Criterion B. We used IRT to identify (a) how each Criterion B symptom corresponded with binge-eating severity in a transdiagnostic binge-eating sample and (b) how well each symptom differentiated individuals with differing levels of severity. METHOD Participants (N = 219) were adults (80.8% female) with a current ED that included objective binge-eating episodes assessed via semi-structured interview. A two-parameter logistic IRT model evaluated how endorsement of each Criterion B symptom corresponded with the level of latent binge-eating severity. RESULTS "Eating large amounts when not hungry" and "eating alone" reflected the highest binge-eating severity. "Eating alone" was the best discriminator across different binge-eating severity levels, whereas "uncomfortably full" was the poorest discriminator across binge-eating severity levels. DISCUSSION Criterion B symptoms were not interchangeable in terms of what level of binge-eating severity corresponded with symptom endorsement. "Eating large amounts when not hungry" or "eating alone" may signify elevated binge-eating severity, whereas "uncomfortably full" and "feeling disgusted/depressed/guilty" were not necessarily indicative of elevated severity. Results suggested that Criterion B may need to be revised to eliminate symptoms that are redundant with other binge-eating diagnostic criteria.

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
This randomized controlled trial (RCT) tested effectiveness of adaptive SMART stepped-care treatment to "standard" behavioral weight loss (BWL [standard]) for patients with binge-eating disorder (BED) and obesity. One hundred ninety-one patients were randomly assigned to 6 months of BWL (standard; n = 39) or stepped care (n = 152). Within stepped care, patients started with BWL for 1 month; treatment responders continued BWL, whereas nonresponders switched to cognitive-behavioral therapy (CBT), and patients receiving stepped care were additionally randomized to weight-loss medication or placebo (double-blind) for the remaining 5 months. Independent assessments were performed reliably at baseline, throughout treatment, and posttreatment. Intent-to-treat (ITT) analyses of remission rates (zero binges/month) revealed that BWL (standard) and stepped care did not differ (74.4% vs. 66.5%); within stepped care, remission rates ranged 40.0% to 83.3%, with medication significantly superior to placebo (overall) and among nonresponders switched to CBT. Mixed-models analyses of binge-eating frequency revealed significant time effects, but BWL (standard) and stepped care did not differ; within stepped care, medication was significantly superior to placebo and among nonresponders switched to CBT. Mixed models revealed significant weight loss, but BWL (standard; 5.1% weight-loss) and stepped care (5.8% weight-loss) did not differ; within stepped care (range = 0.4% to 8.8% weight-loss), medication was significantly superior to placebo and among both responders continued on BWL and nonresponders switched to CBT. In summary, BWL (standard) and adaptive stepped-care treatments produced robust improvements in binge eating and weight loss in patients with BED/obesity. Within adaptive stepped care, weight-loss medication enhanced outcomes for BED/obesity. Implications for clinical practice and future adaptive designs are offered.

Abstract
Type 2 diabetes mellitus (T2DM) is associated with an increased risk of disordered eating behaviors including binge eating disorder (BED). Comorbid BED in patients with T2DM has been associated with adverse clinical outcomes such as higher body mass index (BMI) and depressive symptoms. Identifying and addressing this disorder in patients with T2DM is a significant challenge for health-care providers. The purpose of this narrative review is to discuss current perspectives on BED in the context of T2DM with implications for screening and management of these highly comorbid conditions. BED continues to be underrecognized and underdiagnosed. However, there are established tools that providers can use to screen for BED such as the SCOFF Questionnaire and Questionnaire on Eating and Weight Patterns-5. There are several effective treatments for BED including cognitive behavioral therapy, interpersonal therapy, and lisdexamfetamine dimesylate. However, few studies have examined the effects of these treatments in patients with co-morbid T2DM and BED.

Abstract
BACKGROUND Current guidelines recommend cognitive behavior therapy (CBT) as the treatment of choice for binge eating disorder (BED). Although CBT is quite effective, a substantial number of patients do not reach abstinence from binge eating. To tackle this problem, various theoretical conceptualizations and treatment models have been proposed. Dialectical behavior therapy (DBT), focusing on emotion regulation, is one such model. Preliminary evidence comparing DBT adapted for BED (DBT-BED) to CBT is promising but the available data do not favor one treatment over the other. The aim of this study is to evaluate outcome of DBT-BED, compared to a more intensive eating disorders-focused form of cognitive behavior therapy (CBT+), in individuals with BED who are overweight and engage in emotional eating. METHODS Seventy-four obese patients with BED who reported above average levels of emotional eating were quasi-randomly allocated to one of two manualized 20-session group treatments: DBT-BED (n = 41) or CBT+ (n = 33). Intention-to-treat outcome was examined at post-treatment and at 6-month follow-up using general or generalized linear models with multiple imputation. RESULTS Overall, greater improvements were observed in CBT+. Differences in number of objective binge eating episodes at end of treatment, and eating disorder psychopathology (EDE-Q Global score) and self-esteem (EDI-3 Low Self-Esteem) at follow-up reached statistical significance with medium effect sizes (Cohen's d between .46 and .59). Of the patients in the DBT group, 69.9% reached clinically significant change at end of the treatment vs 65.0% at follow-up. Although higher, this was not significantly different from the patients in the CBT+ group (52.9% vs 45.8%). CONCLUSIONS The results of this study show that CBT+ produces better outcomes than the less intensive DBT-BED on several measures. Yet, regardless of the dose-difference, the data suggest that DBT-BED and CBT+ lead to comparable levels of clinically meaningful change in global eating disorder psychopathology. Future recommendations include the need for dose-matched comparisons in a sufficiently powered randomized controlled trial, and the need to determine mediators and moderators of treatment outcome.

Abstract
Enhanced Cognitive Behavioral Therapy (CBT-E) is an evidence-based treatment for bulimia nervosa (BN), which can be delivered individually or in a group format. This case study describes a young adult female’s progress through a CBT-E group program at an Australian community outpatient eating disorder service. She completed 20 sessions over 10 weeks. The client was administered measures for eating disorder symptoms, depression, anxiety, stress, stage of change, and clinical impairment at pre- and posttreatment. She improved on global eating disorder symptoms, food restriction, eating concern, and her stage of change. Her weight and shape concerns remained unchanged. Her levels of depression, anxiety, and stress significantly increased after treatment, highlighting the need for concurrent treatment for these comorbidities. These results support the developing literature on the efficacy of CBT-E for BN and describe in detail the progress of an individual, including their progress and challenges within a group intervention.

Abstract
OBJECTIVE This report evaluates a dissonance-based group eating disorder treatment designed to be a cost-effective front-line transdiagnostic treatment that could be more widely implemented than extant treatments that are more intensive and expensive relative to a supportive mindfulness group treatment typical of that offered at colleges. METHOD Young women with eating disorders (N = 84) were randomized to 8-week dissonance-based Body Project treatment (BPT) or supportive mindfulness treatment, completing diagnostic interviews and questionnaires at pretest, posttest, and 6-month follow up. RESULTS Regarding primary outcomes, by 6-month follow up 77% of BPT participants no longer met diagnosis for an eating disorder versus 60% of supportive mindfulness participants (relative risk ratio = 2.22; 95% CI [1.01, 4.93]), though groups did not differ on eating disorder symptom change. Regarding secondary outcomes, BPT versus supportive mindfulness participants showed significantly lower dissonance about affirming the thin ideal at posttest and 6-month follow up (d = .38 and .32), body dissatisfaction at posttest and 6-month follow up (d = .62 and .62), negative affect at posttest and 6-month follow up (d = .49 and .48), and functional impairment (d = .36) at 6-month follow up; differences in thin-ideal internalization and abstinence from binge eating and compensatory behaviors were not significant. CONCLUSIONS Whereas both treatments appeared effective, BPT produced larger effects and significantly greater remission of eating disorder diagnoses than a credible alternative treatment, which is very rare for trials that have compared active eating disorder treatments. Results suggest it would be useful to refine BPT and conduct target engagement research and efficacy trials. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Abstract
Factorial experimental designs have many applications in the behavioral sciences. In the context of intervention development, factorial experiments play a critical role in building and optimizing high-quality, multicomponent behavioral interventions. One challenge in implementing factorial experiments in the behavioral sciences is that individuals are often clustered in social or administrative units and may be more similar to each other than to individuals in other clusters. This means that data are dependent within clusters. Power planning resources are available for factorial experiments in which the multilevel structure of the data is due to individuals' membership in groups that existed before experimentation. However, in many cases clusters are generated in the course of the study itself. Such experiment-induced clustering (EIC) requires different data analysis models and power planning resources from those available for multilevel experimental designs in which clusters exist prior to experimentation. Despite the common occurrence of both experimental designs with EIC and factorial designs, a bridge has yet to be built between EIC and factorial designs. Therefore, resources are limited or nonexistent for planning factorial experiments that involve EIC. This article seeks to bridge this gap by extending prior models for EIC, developed for single-factor experiments, to factorial experiments involving various types of EIC. We also offer power formulas to help investigators decide whether a particular experimental design involving EIC is feasible. We demonstrate that factorial experiments can be powerful and feasible even with EIC. We discuss design considerations and directions for future research. (PsycINFO Database Record

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 To systematically review the efficacy of psychological, pharmacological, and combined treatments for binge eating disorder (BED). Method Systematic search and meta-analysis. Results We found 45 unique studies with low/medium risk of bias, and moderate support for the efficacy of cognitive behavior therapy (CBT) and CBT guided self-help (with moderate quality of evidence), and modest support for interpersonal psychotherapy (IPT), selective serotonin reuptake inhibitors (SSRI), and lisdexamfetamine (with low quality of evidence) in the treatment of adults with BED in terms of cessation of or reduction in the frequency of binge eating. The results on weight loss were disappointing. Only lisdexamfetamine showed a very modest effect on weight loss (low quality of evidence). While there is limited support for the long-term effect of psychological treatments, we have currently no data to ascertain the long-term effect of drug treatments. Some undesired side effects are more common in drug treatment compared to placebo, while the side effects of psychological treatments are unknown. Direct comparisons between pharmaceutical and psychological treatments are lacking as well as data to generalize these results to adolescents. Conclusion We found moderate support for the efficacy of CBT and guided self-help for the treatment of BED. However, IPT, SSRI, and lisdexamfetamine received only modest support in terms of cessation of or reduction in the frequency of binge eating. The lack of long-term follow-ups is alarming, especially with regard to medication. Long-term follow-ups, standardized assessments including measures of quality of life, and the study of underrepresented populations should be a priority for future research.

Abstract
WHAT IS KNOWN ON THE SUBJECT?: Weight suppression (WS) has been suggested to predict outcome following psychological treatment for an eating disorder (ED). Some findings are contradictory and have not been considered systematically. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The review suggests that weight gain at post-treatment is reliably predicted by pretreatment WS, but findings regarding other outcomes (e.g., treatment dropout) are less consistent. Approximate effect sizes for observed relationships are identified, alongside support for biobehavioural theories of metabolic adaptation to weight loss. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Degree of WS at pretreatment is associated with weight gain and is important for clinicians to consider before offering treatment to patients with EDs. Patients high in WS might benefit from further support (e.g., psychoeducation) prior to beginning treatment. ABSTRACT: Introduction Weight suppression (WS-the difference between highest body weight and current body weight) has been proposed as a predictor of treatment outcome within eating disorders (EDs), although this hypothesis has not been consistently supported. Aim/Question Review the association between pretreatment WS and outcome following psychological treatment for EDs. Method A comprehensive electronic database search for published and unpublished literature from 1979 to 2017. Reference lists were also inspected. Eligibility criteria were determined according to relevant guidelines and a quality appraisal was conducted. Results Twelve studies met inclusion criteria (one was subsequently excluded based on insufficient data). Greater WS was generally associated with weight gain at post-treatment although not with other treatment outcomes. Discussion The existing evidence, with data from 1,566 participants, is summarized according to three main post-treatment outcomes: weight change; treatment completion; and symptom abstinence. Patients with disordered eating and greater WS may need to gain more weight than others during treatment to achieve good outcomes. Recommendations for future studies are provided. Implications for practice Evidence-based treatments for EDs may benefit from considering WS when planning treatment, such as further psychoeducation on weight changes. Societal interventions regarding promotion of healthy eating may also draw on these findings.

Abstract
OBJECTIVE Treatment for binge eating disorder (BED), a condition associated with both excess adiposity and psychological distress, has not typically produced significant weight loss despite reducing binge eating. Characterizing factors that promote or inhibit weight loss in individuals with co-occurring BED and obesity may help explain overall nonsignificant weight changes during treatment. METHODS In this study, 189 adults with BED participated in a randomized clinical trial evaluating the efficacy of 5 months of cognitive behavioral therapy. Assessments included measured height and weight at baseline, midtreatment, end of treatment (EOT), and 6-month follow-up, the Eating Disorder Examination interview, and questionnaires. RESULTS During treatment, there was a mean weight gain of 1.3 ± 12.0 lb. Twenty-two percent of the sample lost ≥ 5 lb, and 25% of the sample gained ≥ 8 lb. Results showed that baseline objective binge eating episodes predicted weight over treatment. Changes in weight were significantly positively related to concurrent changes in shape concern, weight concern, and disinhibition, but not binge eating episodes. Changes in objective binge eating episodes from baseline to EOT were associated with changes in weight from EOT to follow-up. CONCLUSIONS Further investigation of eating behavior during BED treatment to understand the energy balance contributions to weight change or stability is warranted.

Correlates of weight-related quality of life among individuals with binge eating disorder before and after cognitive behavioral therapy. Eat Behav 2017; 27:1-6. [PMID: 28843136 PMCID: PMC5700842 DOI: 10.1016/j.eatbeh.2017.08.001] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Revised: 08/16/2017] [Accepted: 08/17/2017] [Indexed: 01/12/2023]
Abstract
Individuals with obesity and binge eating disorder (BED) report poorer weight-related quality of life (WRQOL) compared to individuals with obesity alone. Cognitive behavioral therapy (CBT), the best available treatment for BED, does not consistently produce weight loss or improvements in weight QOL. The purpose of the current study was to examine baseline and longitudinal associations between eating-related and psychosocial variables and dimensions of weight QOL. We examined associations between predictor variables, including body mass index (BMI), eating disorder (ED) psychopathology, and psychosocial factors, in relation to three dimensions of WRQOL among 171 patients whom received CBT for BED. Participants completed interviews and self-report measures at baseline prior to CBT and at end of treatment. At baseline the following associations were significant: BMI, ED psychopathology, and self-esteem were associated with weight-related self-esteem; gender, BMI, and self-esteem were associated with weight-related public distress (i.e., stigma and worry in public because of one's weight); and age, BMI, and ED psychopathology were associated with weight-related physical function. At end of treatment, the following associations were significant: changes in ED psychopathology and coping predicted weight-related self-esteem; changes in coping and self-esteem predicted weight-related public distress; and changes in BMI and subjective binge eating predicted weight-related physical function. Overall, changes in a number of ED and associated symptoms were associated with improvements in WRQOL.

Abstract
Understanding factors that contribute to eating disorders, which affect 13% of females, is critical to developing effective prevention and treatment programs. In this paper, we summarize results from prospective studies that identified factors predicting onset and persistence of eating disorders and core symptom dimensions. Next, implications for intervention targets for prevention, and treatment interventions from the risk- and maintenance-factor findings are discussed. Third, given that evidence suggests eating disorders are highly heritable, implying biological risk and maintenance factors for eating disorders, we offer working hypotheses about biological factors that might contribute to eating disorders, based on extant risk factor findings, theory, and cross-sectional studies. Finally, potentially fruitful directions for future research are presented. We suggest that it would be useful for experimental therapeutics trials to evaluate the effects of reducing the risk factors on future onset of eating pathology and on reducing maintenance factors on the risk for persistence of eating pathology, and encourage researchers to utilize prospective high-risk studies so that knowledge regarding potential intervention targets for prevention and treatment interventions for eating disorders can be advanced. Using the most rigorous research designs should help improve the efficacy of prevention and treatment interventions for eating disorders.

Abstract
OBJECTIVE The DSM-5 includes severity specifiers (i.e., mild, moderate, severe, extreme) for anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED), which are determined by weight status (AN) and frequencies of binge-eating episodes (BED) or inappropriate compensatory behaviors (BN). Given limited data regarding the validity of eating disorder (ED) severity specifiers, this study examined the concurrent and predictive validity of severity specifiers in AN, BN, and BED. METHOD Adults with AN (n = 109), BN (n = 76), and BED (n = 216) were identified from previous datasets. Concurrent validity was assessed by measures of ED psychopathology, depression, anxiety, quality of life, and physical health. Predictive validity was assessed by ED symptoms at the end of the treatment in BN and BED. RESULTS Severity categories did not differ in baseline validators, though the mild AN group evidenced greater ED symptoms compared to the severe group. In BN, greater severity was related to greater end of treatment binge-eating and compensatory behaviors, and lower likelihood of abstinence; however, in BED, greater severity was related to lower ED symptoms at the end of the treatment. DISCUSSION Results demonstrated limited support for the validity of DSM-5 severity specifiers. Future research is warranted to explore additional validators and possible alternative indicators of severity in EDs.

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
This study examined self-discrepancy, a construct of theoretical relevance to eating disorder (ED) psychopathology, across different types of EDs. Individuals with anorexia nervosa (AN; n = 112), bulimia nervosa (BN; n = 72), and binge eating disorder (BED; n = 199) completed semi-structured interviews assessing specific types of self-discrepancies. Results revealed that actual:ideal (A:I) discrepancy was positively associated with AN, actual:ought (A:O) discrepancy was positively associated with BN and BED, and self-discrepancies did not differentiate BN from BED. Across diagnoses, A:O discrepancy was positively associated with severity of purging, binge eating, and global ED psychopathology. Further, there were significant interactions between diagnosis and A:O discrepancy for global ED psychopathology and between diagnosis and A:I discrepancy for binge eating and driven exercise. These results support the importance of self-discrepancy as a potential causal and maintenance variable in EDs that differentiates among different types of EDs and symptom severity.

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
BACKGROUND Dropout rates in binge eating disorder (BED) treatment are high (17-30%), and predictors of dropout are unknown. METHOD Participants were 376 patients following an intensive outpatient cognitive behavioural therapy programme for BED, 82 of whom (21.8%) dropped out of treatment. An exploratory logistic regression was performed using eating disorder variables, general psychopathology, personality and demographics to identify predictors of dropout. RESULTS Binge eating pathology, preoccupations with eating, shape and weight, social adjustment, agreeableness, and social embedding appeared to be significant predictors of dropout. Also, education showed an association to dropout. DISCUSSION This is one of the first studies investigating pre-treatment predictors for dropout in BED treatment. The total explained variance of the prediction model was low, yet the model correctly classified 80.6% of cases, which is comparable to other dropout studies in eating disorders.

Abstract
OBJECTIVE To describe the frequency of self-weighing and reactions to prescribed weekly weighing among individuals with eating disorder (ED) diagnoses, and to compare individuals weighing more or less frequently on mass index (BMI) and the Eating Disorder Examination (EDE) subscales. METHOD Baseline EDE and demographics from five studies (N = 758). RESULTS Self-weighing was most frequent among individuals with anorexia nervosa (AN), followed by those with bulimia nervosa (BN) and binge eating disorder (BED). On average, participants reacted moderately negative to prescribed weekly weighing. No relationship between weighing frequency and BMI was evident in any sample. There was indication of greater pathology (i.e., restraint, shape concern, weight concern, global) in AN with more frequent weighing. In BN, mixed evidence emerged to support a relationship between more frequent weighing and higher shape concern, weight concern, and global score. In BED, higher restraint was found in those who weighed versus those who did not. DISCUSSION Weighing frequency in each eating disorder (ED) sample was to some extent associated with greater ED severity, but not BMI. Future research should examine relationships between self-weighing, reactions to changing weighing frequency, and ED symptomatology in both ED and non-ED groups to understand the impact of self-weighing in heterogeneous populations. © 2016 Wiley Periodicals, Inc.

Abstract
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.

Abstract
We performed a qualitative review of treatment studies of binge eating disorder (BED), focusing on randomized clinical trials (RCTs). Limited effectiveness has been demonstrated for self-help strategies, and substantial effectiveness has been shown for cognitive behavioral therapy (CBT) and interpersonal therapy (IPT). CBT and IPT may each be more effective than behavior weight loss therapy (BWLT) for reducing binge eating over the long term. The stimulant pro-drug lisdexamfetamine dimesylate (LDX) is the only drug approved by the FDA for the treatment of BED in adults based on 2 pivotal RCTs. Topiramate also decreases binge eating behavior, but its use is limited by its adverse event profile. Antidepressants may be modestly effective over the short term for reducing binge eating behavior and comorbid depressive symptoms, but are not associated with clinically significant weight loss. A RCT presented in abstract form suggests that intranasal naloxone may decrease time spent binge eating. There is no RCT of obesity surgery in BED, but many patients with BED seek and receive such surgery. While some studies suggest patients with BED and obesity do just as well as patients with obesity alone, other studies suggest that patients with BED have more post-operative complications, less weight loss, and more weight regain. This evidence suggests that patients with BED would benefit from receiving highly individualized treatment.

Abstract
OBJECTIVE This study examined whether having a history of anorexia nervosa (AN) or bulimia nervosa (BN) is associated with response to treatment in adults with binge eating disorder (BED). METHOD Data from 189 adults diagnosed with BED who were randomly assigned to one of three group cognitive-behavioral (CBT) treatments were analyzed to compare those with and without a history of AN/BN. RESULTS A total of 16% of the sample had a history of AN/BN. The BED subgroup with a history of AN/BN presented with higher rates of mood disorders and greater eating-related symptom severity at baseline. Participants with a history of AN/BN also had higher global eating disorder (ED) symptoms at end of treatment (EOT), and more frequent objective binge-eating episodes at EOT and 12-month follow-up. DISCUSSION These findings suggest that in adults with BED, a history of AN/BN is predictive of greater eating-related symptom severity following group-based CBT and poorer short- and long-term binge-eating outcomes. These findings suggest that considering ED history in the treatment of adults with BED may be clinically useful.

Abstract
This study examined whether perceptions of group dynamics early in treatment predicted eating disorder outcomes in a sample of adults (N = 190) with binge eating disorder (BED) who participated in a 15-session group cognitive behavior therapy (gCBT) treatment with differing levels of therapist involvement (therapist led, therapist assisted, and self-help). The group dynamic variables included the Engaged subscale of the Group Climate Questionnaire--Short Form and the Group Attitude Scale, measured at session 2 and session 6. Treatment outcome was assessed in terms of global eating disorder severity and frequency of binge eating at end of treatment, 6-month, and 12-month follow-up. Session 2 engagement and group attitudes were associated with improved outcome at 12-month follow-up. No other group dynamic variables were significantly associated with treatment outcome. Group dynamic variables did not differ by levels of therapist involvement. Results indicate that early engagement and attitudes may be predictive of improved eating disorder psychopathology at 12 month follow-up. However, the pattern of mostly insignificant findings indicates that in gCBT, group process variables may be less influential on outcomes relative to other treatment components. Additionally, participants were able to engage in group treatment regardless of level of therapist involvement.

Abstract
INTRODUCTION Binge Eating Disorders is a clinical syndrome recently coded as an autonomous diagnosis in DSM-5. Individuals affected by Binge Eating Disorder (BED) show significantly lower quality of life and perceived health and higher psychological distress compared to the non-BED obese population. BED treatment is complex due to clinical and psychological reasons but also to high drop-out and poor stability of achieved goals. The purpose of this review is to explore the available data on this topic, outlining the state-of-the-art on both diagnostic issues and most effective treatment strategies. METHODS We identified studies published in the last 6 years searching the MeSH Term "binge eating disorder", with specific regard to classification, diagnosis and treatment, in major computerized literature databases including: Medline, PubMed, PsychINFO and Science Direct. RESULTS A total of 233 studies were found and, among them, 71 were selected and included in the review. REVIEW Although Binge Eating Disorder diagnostic criteria showed empirical consistency, core psychopathology traits should be taken into account to address treatment strategies. The available body of evidence shows psychological treatments as first line interventions, even if their efficacy on weight loss needs further exploration. Behavioral and self-help interventions evidenced some efficacy in patients with lower psychopathological features. Pharmacological treatment plays an important role, but data are still limited by small samples and short follow-up times. The role of bariatric surgery, a recommended treatment for obesity that is often required also by patients with Binge Eating Disorder, deserves more specific studies. Combining different interventions at the same time does not add significant advantages, planning sequential treatments, with more specific interventions for non-responders, seems to be a more promising strategy. CONCLUSIONS Despite its recent inclusion in DSM-5 as an autonomous disease, BED diagnosis and treatment strategies deserve further deepening. A multidisciplinary and stepped-care treatment appears as a promising management strategy. Longer and more structured follow-up studies are required, in order to enlighten long term outcomes and to overcome the high dropout rates affecting current studies.

Abstract
The aim of this naturalistic study was to identify pretreatment predictors of response to cognitive behaviour therapy in treatment-seeking patients with binge eating disorder (BED; N = 304). Furthermore, we examined end-of-treatment factors that predict treatment outcome 6 months later (N = 190). We assessed eating disorder psychopathology, general psychopathology, personality characteristics and demographic variables using self-report questionnaires. Treatment outcome was measured using the bulimia subscale of the Eating Disorder Inventory 1. Predictors were determined using hierarchical linear regression analyses. Several variables significantly predicted outcome, four of which were found to be both baseline predictors of treatment outcome and end-of-treatment predictors of follow-up: Higher levels of drive for thinness, higher levels of interoceptive awareness, lower levels of binge eating pathology and, in women, lower levels of body dissatisfaction predicted better outcome in the short and longer term. Based on these results, several suggestions are made to improve treatment outcome for BED patients.

Abstract
The authors conducted a pilot trial of a new dissonance-based group eating disorder treatment designed to be a cost-effective front-line transdiagnostic treatment that could be more widely disseminated than extant individual or family treatments that are more expensive and difficult to deliver. Young women with a DSM-5 eating disorder (N = 72) were randomized to an 8-week dissonance-based Counter Attitudinal Therapy group treatment or a usual care control condition, completing diagnostic interviews and questionnaires at pre, post, and 2-month follow-up. Intent-to-treat analyses revealed that intervention participants showed greater reductions in outcomes than usual care controls in a multivariate multilevel model (χ(2)[6] = 34.1, p < .001), producing large effects for thin-ideal internalization (d = .79), body dissatisfaction (d = 1.14), and blinded interview-assessed eating disorder symptoms (d = .95), and medium effects for dissonance regarding perpetuating the thin ideal (d = .65) and negative affect (d = .55). Midway through this pilot we refined engagement procedures, which was associated with increased effect sizes (e.g., the d for eating disorder symptoms increased from .51 to 2.30). This new group treatment produced large reductions in eating disorder symptoms, which is encouraging because it requires about 1/20th the therapist time necessary for extant individual and family treatments, and has the potential to provide a cost-effective and efficacious approach to reaching the majority of individuals with eating disorders who do not presently received treatment.

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 Picking or ribbling (P&N) is a newly studied eating behavior characterized by eating in an unplanned and repetitious manner in between meals and snacks. This behavior seems to be related to poorer weight loss outcomes after bariatric surgery for weight loss in severely obese patients, but clarification is still required regarding its value in other clinical samples. The purpose of this study was to investigate the frequency of P&N across different eating disorder samples, as well as to examine its association with psychopathological eating disorder features. METHOD Our sample included treatment-seeking adult participants, recruited for five different clinical trials: 259 binge eating disorder (BED); 264 bulimia nervosa (BN), and 137 anorexia nervosa (AN). Participants were assessed using the Eating Disorders Examination interview before entering the clinical trials. RESULTS P&N was reported by 44% of the BED; 57.6% of the BN; and 34.3% of the AN participants. No association was found between P&N and BMI, the presence of compensatory behaviors, binge eating, or any of the eating disorder examination subscales. DISCUSSION This study suggests that P&N behavior is highly prevalent across eating disorder diagnoses, but it is not associated with psychopathology symptoms or other eating disordered behaviors.

Abstract
OBJECTIVE The primary goal of this article is to examine and clarify characteristics of binge eating in individuals with binge eating disorder (BED), particularly the duration of binge eating episodes, as well as potential differences between individuals with shorter compared to longer binge eating episodes. METHOD Two studies exploring binge eating characteristics in BED were conducted. Study 1 examined differences in clinical variables among individuals (N = 139) with BED who reported a short (<2 h) versus long (≥ 2 h) average binge duration. Study 2 utilized an ecological momentary assessment design to examine the duration and temporal pattern of binge eating episodes in the natural environment in a separate sample of nine women with BED. RESULTS Participants in Study 1 who were classified as having long duration binge eating episodes displayed greater symptoms of depression and lower self-esteem, but did not differ on other measures of eating disorder symptoms, compared to those with short duration binge eating episodes. In Study 2, the average binge episode duration was approximately 42 min, and binge eating episodes were most common during the early afternoon and evening hours, as well as more common on weekdays versus weekends. DISCUSSION Past research on binge episode characteristics, particularly duration, has been limited to studies of binge eating episodes in bulimia nervosa. This study contributes to the existing literature on characteristics of binge eating in BED.

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
This study examined the efficacy of guided self-help based on dialectical behaviour therapy (DBTgsh) for binge eating disorder (BED). Individuals (88.3% female; mean 42.8 years) were randomized to DBTgsh (n=30) or wait-list (WL; n=30). DBTgsh participants received an orientation, DBT manual, and six 20-min support calls over 13 weeks. All participants were assessed pre- and post-treatment using interview and self-report; also, DBTgsh participants were re-assessed six months post-treatment. At treatment end, DBTgsh participants reported significantly fewer past-month binge eating episodes than WL participants (6.0 versus 14.4) and significantly greater rates of abstinence from binge eating (40.0% versus 3.3%). At six-month follow-up, DBTgsh participants reported significantly improved quality of life and reduced ED psychopathology compared to baseline scores. In addition, most improvements in the DBTgsh group were maintained, although binge eating abstinence rates decreased to 30%. These preliminary positive findings indicate that DBTgsh may offer an effective, low-intensity treatment option for BED.

Abstract
OBJECTIVE To update new evidence for psychotherapies in eating disorders (EDs) since 2005-September 2012. METHOD Completed and published in the English language randomized controlled trials (RCTs) were identified by SCOPUS search using terms "bulimia" or "binge eating disorder" (BED) or "anorexia nervosa" (AN) or "eating disorder" and "treatment," and 36 new RCTs met inclusion criteria. RESULTS There has been progress in the evidence for family based treatment in adolescents with AN, for cognitive behavior therapy (CBT) in full and guided forms, and new modes of delivery for bulimia nervosa (BN), BED, and eating disorder not otherwise specified with binge eating. Risk of bias was low to moderate in 22 (61%) of RCTs. DISCUSSION The evidence base for AN has improved and CBT has retained and extended its status as first-line therapy for BN. However, further research is needed, in particular noninferiority trials of active therapies and the best approach to addressing ED features and weight management in co-morbid BED and obesity.

Abstract
The purpose of this study was to use empirical classification based on Latent Profile Analysis to identify subgroups of binge eating disorder (BED) and to evaluate the extent to which these subgroups were predictive of treatment outcome in group cognitive-behavioral therapy (CBT). The Eating Disorder Examination (EDE), Structured Clinical Interview for DSM-IV, and Inventory of Depressive Symptomatology-Self-Report were administered to 259 participants at baseline in a 15-session CBT trial (190 of whom received active treatment). The best fitting model included three profiles: dietary restraint only (DRO; n = 96; 51%); low dietary restraint (LDR; n = 52; 27%); and dietary restraint plus psychopathology (DRP; n = 42; 22%). Regression analyses revealed that after controlling for baseline score and treatment condition, EDE Global scores were lower for the DRO compared to the LDR profile at one year follow-up (p = .047). Class assignment was not predictive of EDE binge eating frequency or abstinence at end of treatment or follow-up. These results suggest that meaningful empirical classes based on eating disorder symptoms, psychopathology, dietary restraint, and BMI can be identified in BED and that these classes may be useful in predicting long-term group CBT outcome.

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.
