Abstract
OBJECTIVE Binge eating disorder (BED), although relatively recently recognized as a distinct clinical syndrome, is the most common eating disorder. BED can occur as a separate phenomenon or in combination with other mental disorders, adding to the overall burden of the illness. Due to the relatively short history of recognizing BED as a distinct disorder, this review aimed to summarize the current knowledge on the co-occurrence of BED with other psychiatric disorders. METHOD This review adhered to the PRISMA guidelines. Multiple databases, such as MEDLINE, MEDLINE Complete, and Academic Search Ultimate, were used to identify relevant studies. Of the 3766 articles initially identified, 63 articles published within the last 13 years were included in this review. This systematic review has been registered through INPLASY (INPLASY202370075). RESULTS The most frequently observed comorbidities associated with BED were mood disorders, anxiety disorders and substance use disorders. They were also related to more severe BED presentations. Other psychiatric conditions frequently associated with BED include reaction to severe stress and adjustment disorders, impulse control disorder, ADHD, personality disorders, behavioral disorders, disorders of bodily distress or bodily experience, and psychotic disorders. Additionally, BED was linked to suicidality and sleep disorders. DISCUSSION The findings highlight the interconnected nature of BED with various psychiatric conditions and related factors, shedding light on the complexity and broader impact of BED on mental health and the need for appropriate screening and appropriately targeted clinical interventions.

Abstract
A significant proportion of those with eating disorders (EDs) do not respond to first-line treatments. This systematic review was conducted to identify whether personality disorders (PDs)/traits predict or moderate ED treatment outcomes and whether these outcomes were differentially influenced by ED or PD diagnostic subtypes, or treatment approach. A comprehensive systematic literature search was conducted using the PRISMA guidelines. A total of seven randomised controlled trials (RCTs) plus four follow-up studies were reviewed investigating the impact of PD and PD traits on treatment outcomes for EDs. The majority indicated that PD had some impact on treatment outcomes. Outcome measures and time-point measurements varied across studies. Included studies suggested that bulimia nervosa treatment outcomes were not hindered by co-morbidity of borderline PD; however, psychiatric impairment remained high at post-treatment and follow-up. Cluster C PDs were found to negatively impact treatment outcomes for binge ED and attrition rates for anorexia nervosa. Included studies suggested that interventions that addressed aspects of personality pathology showed greater main effects for ED treatment outcomes. There is an urgent need for future RCTs on ED treatments to include routine measures of core personality features to allow their impacts to be more thoroughly examined and for psychotherapies to be tailored accordingly.

Abstract
OBJECTIVE Mindfulness-based interventions (MBIs) are being increasingly used as interventions for eating disorders including binge eating. This systematic review and meta-analysis aimed to assess two decades of research on the efficacy of MBIs in reducing binge eating severity. METHODS We searched PubMed, Scopus and Cochrane Library for trials assessing the use of MBIs to treat binge eating severity in both clinical and non-clinical samples. The systematic review and meta-analysis was pre-registered at PROSPERO (CRD42020182395). RESULTS Twenty studies involving 21 samples (11 RCT and 10 uncontrolled samples) met inclusion criteria. Random effects meta-analyses on the 11 RCT samples (n = 618: MBIs n = 335, controls n = 283) showed that MBIs significantly reduced binge eating severity (g = -0.39, 95% CI -0.68, -0.11) at end of trial, but was not maintained at follow-up (g = -0.06, 95% CI, -0.31, 0.20, k = 5). No evidence of publication bias was detected. On the Cochrane Risk of Bias Tool 2, trials were rarely rated at high risk of bias and drop-out rates did not differ between MBIs and control groups. MBIs also significantly reduced depression, and improved both emotion regulation and mindfulness ability. CONCLUSION MBIs reduce binge eating severity at the end of trials. Benefits were not maintained at follow-up; however, only five studies were assessed. Future well-powered trials should focus on assessing diversity better, including more men and people from ethnic minority backgrounds.

Individuals Diagnosed with Binge-Eating Disorder Have DNA Hypomethylated Sites in Genes of the Metabolic System: A Pilot Study. Nutrients 2021; 13:nu13051413.

Abstract
Binge-eating disorder, recently accepted as a diagnostic category, is differentiated from bulimia nervosa in that the former shows the presence of binge-eating episodes and the absence of compensatory behavior. Epigenetics is a conjunct of mechanisms (like DNA methylation) that regulate gene expression, which are dependent on environmental changes. Analysis of DNA methylation in eating disorders shows that it is reduced. The present study aimed to analyze the genome-wide DNA methylation differences between individuals diagnosed with BED and BN. A total of 46 individuals were analyzed using the Infinium Methylation EPIC array. We found 11 differentially methylated sites between BED- and BN-diagnosed individuals, with genome-wide significance. Most of the associations were found in genes related to metabolic processes (ST3GAL4, PRKAG2, and FRK), which are hypomethylated genes in BED. Cg04781532, located in the body of the PRKAG2 gene (protein kinase AMP-activated non-catalytic subunit gamma 2), was hypomethylated in individuals with BED. Agonists of PRKAG2, which is the subunit of AMPK (AMP-activated protein kinase), are proposed to treat obesity, BED, and BN. The present study contributes important insights into the effect that BED could have on PRKAG2 activation.

Abstract
Despite the effectiveness of CBT in reducing shape/weight concerns and dietary restraint, research suggests that patients considered recovered may still exhibit emotional difficulties related to eating disorders (EDs). Dialectical behavior therapy (DBT) has been adapted for a variety of mental disorders characterized by emotion dysregulation and, more recently, for EDs specifically. The current review found that the majority of the research studies employed one of the following three adaptations of DBT for EDs: The Stanford Model, Radically Open-DBT (RO-DBT), or Multidiagnostic ED-DBT (MED-DBT). Therefore, this review sought to review and update the empirical research on each adaptation and (2) offer preliminary recommendations for when and which adaptation of DBT to use when treating adults with EDs. Findings from the empirical literature on DBT and EDs indicate that the Stanford Model has the most rigorous and numerous studies demonstrating efficacy and effectiveness in those diagnosed with binge eating disorder. Fewer studies have been conducted using the Stanford Model with bulimia nervosa; therefore, less strong assertions can be made about DBT with those diagnosed with bulimia. The MED-DBT model has been evaluated in several open trials within higher levels of care with promising results, but the lack of randomized clinically-controlled trials prevents a definitive statement about its efficacy. Finally, research on applying the RO-DBT model to anorexia-nervosa, restricting subtype is in its infancy, prohibiting solid conclusions or recommendations regarding its efficacy or effectiveness.

Abstract
Binge-eating disorder (BED) is a prevalent and serious public health issue. BED is characterized by recurrent out-of-control binge eating episodes in the absence of extreme weight control behavior and is associated with significant psychosocial and physiological impairment. Dialectical Behavior Therapy (DBT), based on the affect regulation model of binge eating, is an evidence-based treatment (EBT) approach for BED. Unfortunately, access to EBTs is often limited due to geographical barriers (i.e., lack of local providers with specialized training in EBTs), lack of financial resources, and/or time constraints. Self-help approaches (via guided and unguided versions) to delivering DBT for BED offer a potentially effective means of more widely disseminating this treatment. Compared to traditional, higher intensity approaches, self-help DBT for BED is less time-consuming, less financially costly, and requires less need for specialized therapist-training. This paper will present how DBT for BED has been adapted for self-help delivery, review the limited but promising research on DBT self-help available to date, and provide directions for future research.

Abstract
OBJECTIVE Increasing evidence suggests that mindfulness- and acceptance-based psychotherapies (MABTs) for bulimia nervosa (BN) and binge eating disorder (BED) may be efficacious; however, little is known about their active treatment components or for whom they may be most effective. METHODS We systematically identified clinical trials testing MABTs for BN or BED through PsychINFO and Google Scholar. Publications were categorized according to analyses of mechanisms of action and moderators of treatment outcome. RESULTS Thirty-nine publications met inclusion criteria. Twenty-seven included analyses of therapeutic mechanisms, and five examined moderators of treatment outcome. Changes were largely consistent with hypothesized mechanisms of MABTs, but substandard mediation analyses, inconsistent measurement tools, and infrequent use of mid-treatment assessment points limited our ability to make strong inferences. DISCUSSION Analyses of mechanisms of action and moderators of outcome in MABTs for BN and BED appear promising, but the use of more sophisticated statistical analyses and adequate replication is necessary.

Problematic and adaptive eating in people with obesity after a DBT-based skills training intervention: 3- and 8-month follow-up and mediation analysis. ACTA ACUST UNITED AC 2019; 32:1. [PMID: 32026132 PMCID: PMC6967300 DOI: 10.1186/s41155-019-0116-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Accepted: 01/02/2019] [Indexed: 11/18/2022]
Abstract
Background Dialectical behavior therapy conceptualizes problematic behaviors as attempts to regulate emotions that occur when the individual lacks effective skills with which to manage his or her emotions and cope with distress. Problematic eating behaviors, e.g., binge and emotional eating, may serve to alleviate aversive emotional states, being highly associated with overweight and obesity. Dialectical behavior therapy skills training has been proven effective in reducing binge eating in several clinical studies. However, few studies reveal the effects of DBT on adaptive eating behaviors or the stability of outcomes. Objectives This study aimed to test the effect of a brief DBT-based skills training intervention, and the stability of outcomes at 3- and 8-month follow-ups. Methods Self-report measures of binge eating, emotional eating, intuitive eating, and mindful eating were taken on 5 timepoints before and after a 10-session DBT skills training intervention (2 baseline measures, 1 post-test, and 2 follow-ups). Data were analyzed using a mixed-model intention-to-treat approach and mediation analysis was conducted with path analysis. Results After the intervention, intuitive eating and mindful eating scores were significantly higher than before the intervention, while emotional eating and binge eating scores were lower. The results remained stable during the follow-up period, with minor fluctuations and small trends towards returning to baseline values for binge eating and emotional eating. Mindful eating partially mediated the improvements in all outcomes. Limitations Given that results are entirely based on self-report measures and that some instruments showed poor reliability, in addition to the high attrition rates, the results should be interpreted as preliminary. Conclusions The results provide evidence that a brief DBT intervention is effective not only in reducing problematic eating but also in increasing adaptive eating, achieving reasonably stable results. Also, the mediation analysis results support the hypothesis that mindful eating partially explains the effects of the intervention on binge and emotional eating. Future research should address the limitations of this study by investigating a more diverse sample, triangulating different measurement strategies, and including other putative mediators.

Abstract
SETTING In a private medical center, 300 patients who underwent a laparoscopic sleeve gastrectomy (LSG) were classified into 4 groups according to their eating behaviors (EB) preoperatively. During a 3-year postoperative follow-up, dietary changes in relation to weight loss were studied. OBJECTIVES To explore the influence of abnormal EB on the outcome of sleeve gastrectomy. BACKGROUND Patients with morbid obesity often suffer from abnormal EB. After LSG, the outcome depends largely on improvement of the feeding behaviors acquired. METHODS This prospective study includes 300 patients who underwent LSG from 2013 to 2014, divided into the following 4 groups: binge eaters, snack eaters, sweet eaters, and volume eaters. RESULTS The average age was 41.65 years, the ratio of male to females was 1 to 2. The average baseline body mass index (BMI) was 42.02. After 3 years, no significant change was found in the number of binge eaters (p = 0.396), but there was an 8.9% increase in snack eaters (p < 0.001), a 12.9% increase in sweet eaters (p < 0.001), and 17.2% increase in healthy eating habits (p < 0.001). Sixty-five (24.8%) patients did not experience changes in their eating patterns. However, after surgery, 24.6% of the patients continued with the same EB and 125 (49.5%) patients changed from one EB to another unhealthy EB. Weight loss, measure as ΔBMI, was similar in each group after 3 years, with a mean BMI of 29.8. When eating habits were related to different features such as gender, sports practice, type of work, smoking, marital status, comorbidities, no influence on the operative results were found. CONCLUSION LSG promotes the reduction of overeaters; however, it promotes a switch between other unhealthy EB. The significant increase in snack eaters and sweet eaters is outstanding, although it did not affect weight loss in the midterm follow-up. Worsening of eating habits after LSG is a common fact.

Abstract
In our review, we focus on self-related constructs in the context of eating disorders with four aims. First, we examine a variety of self-related constructs that have been theoretically and empirically linked to the development and course of eating disorders. In addition to the more well-researched constructs of self-esteem and self-efficacy, we also report on findings related to selflessness, contingent self-worth, self-objectification, ego-syntonicity, self-concept clarity, self-compassion, social comparison, self-oriented perfectionism/self-criticism, and narcissism. Second, we discuss self-related constructs that may be especially relevant to comorbidities common among those with eating disorders. Third, we review intervention and prevention programs where self-related constructs play a prominent role. Lastly, we share future research directions regarding self-related constructs and eating disorders that we believe will advance a deeper understanding of the role of the self in the eating disorders.

Abstract
BACKGROUND Dialectical Behaviour Therapy (DBT) is an evidence-based intervention that has been included in the National Institute of Health and Care Excellence guidelines as a recommended treatment for Borderline Personality Disorder in the UK. However, implementing and sustaining evidence-based treatments in routine practice can be difficult to achieve. This study compared the survival of early and late adopters of DBT as well as teams trained via different training modes (on-site versus off-site), and explored factors that aided or hindered implementation of DBT into routine healthcare settings. METHODS A mixed-method approach was used. Kaplan-Meier survival analyses were conducted to quantify and compare survivability as a measure of sustainability between early and late implementers and those trained on- and off-site. An online questionnaire based on the Consolidated Framework for Implementation Research was used to explore barriers and facilitators in implementation. A quantitative content analysis of survey responses was carried out. RESULTS Early implementers were significantly less likely to survive than late implementers, although, the effect size was small. DBT teams trained off-site were significantly more likely to survive. The effect size for this difference was large. An unequal amount of censored data between groups in both analyses means that findings should be considered tentative. Practitioner turnover and financing were the most frequently cited barriers to implementation. Individual characteristics of practitioners and quality of the evidence base were the most commonly reported facilitators to implementation. CONCLUSIONS A number of common barriers and facilitators to successful implementation of DBT were found among DBT programmes. Location of DBT training may mediate programme survival.

Abstract
OBJECTIVE Few studies have evaluated moderators of mindfulness-based relapse prevention (MBRP) for substance use disorders (SUDs). We tested whether baseline patterns of scores for SUD symptom severity and depression and anxiety symptoms moderated the efficacy of MBRP. METHOD We used a latent class moderation approach with data from a randomized trial of MBRP compared to cognitive-behavioral relapse prevention and treatment as usual (TAU; Bowen et al., 2014; N = 286, 71.8% male, 48.4% non-White, mean age = 38.44 years, SD = 10.92) and a randomized trial comparing MBRP to TAU (Bowen et al., 2009; N = 168, 63.7% male, 44.6% non-White, mean age = 40.45, SD = .28). Indicators for the latent class models were measures of SUD severity (Severity of Dependence Scale and Short Inventory of Problems), depression symptoms (Beck Depression Inventory), and anxiety symptoms (Beck Anxiety Inventory). RESULTS In both trials, 3 latent classes provided the best fit: a high-high class characterized by high SUD severity and depression and anxiety symptoms, a high-low class characterized by high SUD severity and low depression and anxiety symptoms, and a low-low class characterized by low SUD severity and depression and anxiety symptoms. In both trials, we found significant latent Class × Treatment interaction effects: There were significant and large effects of MBRP on substance use outcomes in the high-high and high-low classes, but no MBRP effect in the low-low class. CONCLUSION MBRP may be an optimal treatment for preventing relapse among clients with severe levels of SUD symptoms and depression and anxiety symptoms, as well as clients with only severe SUD symptoms.

Abstract
BACKGROUND Studies demonstrate an association between personality traits and obesity as well as their prognostic influence on weight course. In contrast, only few studies have investigated the association between personality disorders (PDs) and obesity. OBJECTIVE The present review summarizes through a comprehensive and critical evaluation the results of 68 studies identified by database research (PubMed and PsycINFO) covering the last 35 years that investigated the association between PDs, overweight and obesity as well as the predictive value of PDs for the development of obesity and the effectiveness of weight reduction treatments. RESULTS Adults with any PD have a higher risk of obesity. In the female general population, there is an association between avoidant or antisocial PD and severe obesity. Further, women with paranoid or schizotypal PD have a higher risk of obesity. Clinical studies including foremost female participants showed a higher comorbidity of PDs, especially borderline PD and avoidant PD, in binge-eating disorder. Regarding both genders, patients with PD show less treatment success in conservative weight-loss treatment programmes for obesity than patients without PD. CONCLUSIONS In prevention and conservative weight-loss treatment strategies, more care should be taken to address the special needs of patients with comorbid PDs.

Abstract
PURPOSE OF REVIEW This review provides an update on the new Diagnostic and Statistical Manual (DSM) diagnosis of binge-eating disorder (BED) by presenting diagnostic criteria, associated risk factors and co-morbidities, and tools for assessment. An update on the currently available evidence-based treatments for adolescent BED is provided to help with the coordination of treatment planning for identified patients with this condition. RECENT FINDINGS BED is now officially included in the DSM. Research with youth has begun to show improvement from treatments such as cognitive behavioral therapy, previously shown to be useful in adults. SUMMARY BED is common and often begins during youth. The availability of diagnostic criteria, along with increasing knowledge about the condition and available treatments, is expected to result in improved identification and management in younger patients.

Abstract
BACKGROUND Evidence-based practice in eating disorders incorporates three essential components: research evidence, clinical expertise, and patient values, preferences, and characteristics. Conceptualized as a 'three-legged stool' by Sackett et al. in 1996 (BMJ), all of these components of evidence-based practice are considered essential for providing optimal care in the treatment of eating disorders. However, the extent to which these individual aspects of evidence-based practice are valued among clinicians and researchers is variable, with each of these stool 'legs' being neglected at times. As a result, empirical support and patient preferences for treatment are not consistently considered in the selection and implementation of eating disorder treatment. In addition, clinicians may not have access to training to provide treatments supported by research and preferred by patients. Despite these challenges, integrating these three components of evidence-based practice is critical for the effective treatment of eating disorders. DISCUSSION Current research supports the use of several types of psychotherapies, including cognitive-behavioral, interpersonal, and family-based therapies, as well as certain types of medications for the treatment of eating disorders. However, limitations in current research, including sample heterogeneity, inconsistent efficacy, a paucity of data, the need for tailored approaches, and the use of staging models highlight the need for clinical expertise. Although preliminary data also support the importance of patient preferences, values, and perspectives for optimizing treatment, enhancing treatment outcome, and minimizing attrition among patients with eating disorders, the extent to which patient preference is consistently predictive of outcome is less clear and requires further investigation. All three components of evidence-based practice are integral for the optimal treatment of eating disorders. Integrating clinical expertise and patient perspective may also facilitate the dissemination of empirically-supported and emerging treatments as well as prevention programs. Further research is imperative to identify ways in which this three-legged approach to eating disorder treatment could be most effectively implemented.

Abstract
Eating disorders are psychiatric conditions originated from and perpetuated by individual, family and sociocultural factors. The psychosocial approach to treatment and prevention of relapse is crucial. To present an overview of the scientific evidence on effectiveness of psychosocial interventions in treatment of eating disorders. All systematic reviews published by the Cochrane Database of Systematic Reviews - Cochrane Library on the topic were included. Afterwards, as from the least recent date of these reviews (2001), an additional search was conducted at PubMed with sensitive search strategy and with the same keywords used. A total of 101 primary studies and 30 systematic reviews (5 Cochrane systematic reviews), meta-analysis, guidelines or narrative reviews of literature were included. The main outcomes were: symptomatic remission, body image, cognitive distortion, psychiatric comorbidity, psychosocial functioning and patient satisfaction. The cognitive behavioral approach was the most effective treatment, especially for bulimia nervosa, binge eating disorder and the night eating syndrome. For anorexia nervosa, the family approach showed greater effectiveness. Other effective approaches were interpersonal psychotherapy, dialectic behavioral therapy, support therapy and self-help manuals. Moreover, there was an increasing number of preventive and promotional approaches that addressed individual, family and social risk factors, being promising for the development of positive self-image and self-efficacy. Further studies are required to evaluate the impact of multidisciplinary approaches on all eating disorders, as well as the cost-effectiveness of some effective modalities, such as the cognitive behavioral therapy. RESUMO Transtornos alimentares são doenças psiquiátricas originadas de e perpetuadas por fatores individuais, familiares e socioculturais. A abordagem psicossocial é essencial para o tratamento e a prevenção de recaídas. Apresentar uma visão geral das evidências científicas sobre a efetividade das intervenções psicossociais no tratamento de transtornos alimentares. Foram incluídas todas as revisões sistemáticas publicadas no Banco de Dados de Revisões Sistemáticas da Cochrane Library. Posteriormente, a partir da data menos recente destas revisões (2001), realizou-se uma busca adicional no PubMed, com estratégia de busca sensibilizada e com os mesmos descritores utilizados antes. No total, foram incluídos 101 estudos primários e 30 revisões sistemáticas (5 revisões sistemáticas da Cochrane), metanálises, diretrizes ou revisões narrativas da literatura. Os principais desfechos foram remissão de sintomas, imagem corporal, distorção cognitiva, comorbidade psiquiátrica, funcionamento psicossocial e satisfação do paciente. A abordagem cognitivo-comportamental foi o tratamento mais efetivo, principalmente para bulimia nervosa, transtorno da compulsão alimentar periódica e síndrome do comer noturno. Para anorexia nervosa, a abordagem familiar demonstrou maior efetividade. Outras abordagens efetivas foram psicoterapia interpessoal, terapia comportamental dialética, terapia de apoio e manuais de autoajuda. Além disso, houve um número crescente de abordagens preventivas e promocionais que contemplaram fatores de risco individuais, familiares e sociais, sendo promissoras para o desenvolvimento da autoimagem positiva e autoeficácia. São necessários mais estudos que avaliem o impacto de abordagens multidisciplinares em todos transtornos alimentares, além da relação custo-efetividade de algumas modalidades efetivas, como a terapia cognitivo-comportamental.

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
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 This article addresses the state of the art concerning the treatment of binge eating disorder (BED). Pharmacological and psychotherapeutic strategies, together with issues concerning the involvement in bariatric surgery are considered. METHOD A Medline enquiry of published articles was performed using the following keywords: BED, pharmacological treatment, duloxetine, venlafaxine, SSRI, psychotherapy, bariatric surgery; reviews and single-case studies were also analyzed. RESULTS Psychological interventions that have shown efficacy in the treatment of Bulimia Nervosa have also been tested in BED with positive results, in particular modified cognitive behavioral therapy, interpersonal therapy and dialectical behavior therapy. In addition pharmacotherapy with SSRIs is successful in transiently reducing binge-eating and body weight; the SNRI duloxetine is effective for reducing binge eating, and global severity of illness with a controversial effect on body weight; both topiramate and sibutramine seem promising, but their use is restricted due to labeling and side effect limitations, respectively. Finally, adequate psychological/pharmacological support can help BED patients obtain positive outcomes from bariatric surgery. CONCLUSION Studies on BED treatment are burdened by several limitations as selection biases (e.g. mostly women and overweight), small samples, high drop-out rates and placebo response.

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 To examine predictors and moderators of response to cognitive behavioral therapy (CBT) and medication treatments for binge-eating disorder (BED). METHOD 108 BED patients in a randomized double-blind placebo-controlled trial testing CBT and fluoxetine treatments were assessed prior, throughout, and posttreatment. Demographic factors, psychiatric and personality disorder comorbidity, eating disorder psychopathology, psychological features, and 2 subtyping methods (negative affect, overvaluation of shape/weight) were tested as predictors and moderators for the primary outcome of remission from binge eating and 4 secondary dimensional outcomes (binge-eating frequency, eating disorder psychopathology, depression, and body mass index). Mixed-effects models analyzed all available data for each outcome variable. In each model, effects for baseline value and treatment were included with tests of both prediction and moderator effects. RESULTS Several demographic and clinical variables significantly predicted and/or moderated outcomes. One demographic variable signaled a statistical advantage for medication only (younger participants had greater binge-eating reductions), whereas several demographic and clinical variables (lower self-esteem, negative affect, and overvaluation of shape/weight) signaled better improvements if receiving CBT. Overvaluation was the most salient predictor/moderator of outcomes. Overvaluation significantly predicted binge-eating remission (29% of participants with vs. 57% of participants without overvaluation remitted). Overvaluation was especially associated with lower remission rates if receiving medication only (10% vs. 42% for participants without overvaluation). Overvaluation moderated dimensional outcomes: Participants with overvaluation had significantly greater reductions in eating disorder psychopathology and depression levels if receiving CBT. Overvaluation predictor/moderator findings persisted after controlling for negative affect. CONCLUSIONS Our findings have clinical utility for prescription of CBT and medication and implications for refinement of the BED diagnosis.
