Abstract
BACKGROUND Controlled research examining maintenance treatments for responders to acute interventions for binge-eating disorder (BED) is limited. This study tested efficacy of lisdexamfetamine (LDX) maintenance treatment amongst acute responders. METHODS This prospective randomized double-blind placebo-controlled single-site trial, conducted March 2019 to September 2023, tested LDX as maintenance treatment for responders to acute treatments with LDX-alone or with cognitive-behavioral therapy (CBT + LDX) for BED with obesity. Sixty-one (83.6% women, mean age 44.3, mean BMI 36.1 kg/m2) acute responders were randomized to LDX (N = 32) or placebo (N = 29) for 12 weeks; 95.1% completed posttreatment assessments. Mixed-models and generalized-estimating equations comparing maintenance LDX v. placebo included main/interactive effects of acute (LDX or CBT + LDX) treatments to examine their predictive/moderating effects. RESULTS Relapse rates (to diagnosis-level binge-eating frequency) following maintenance treatments were 10.0% (N = 3/30) for LDX and 17.9% (N = 5/28) for placebo; intention-to-treat binge-eating remission rates were 59.4% (N = 19/32) and 65.5% (N = 19/29), respectively. Maintenance LDX and placebo did not differ significantly in binge-eating but differed in weight-loss and eating-disorder psychopathology. Maintenance LDX was associated with significant weight-loss (-2.3%) whereas placebo had significant weight-gain (+2.2%); LDX and placebo differed significantly in weight-change throughout treatment and at posttreatment. Eating-disorder psychopathology remained unchanged with LDX but increased significantly with placebo. Acute treatments did not significantly predict/moderate maintenance-treatment outcomes. CONCLUSIONS Adults with BED/obesity who respond to acute lisdexamfetamine treatment (regardless of additionally receiving CBT) had good maintenance during subsequent 12-weeks. Maintenance lisdexamfetamine, relative to placebo, did not provide further benefit for binge-eating but was associated with significantly better eating-disorder psychopathology outcomes and greater weight-loss.

Abstract
OBJECTIVE To explore dietary-restraint as a mediator of binge eating and weight-loss outcomes within a randomized controlled trial comparing cognitive-behavioral therapy (CBT) and behavioral weight loss (BWL) for binge-eating disorder (BED) with obesity. METHODS Ninety participants were randomly assigned to CBT or BWL and assessed by evaluators blinded to conditions at pretreatment, throughout-, and post-treatment (6 months). Three dietary-restraint measures (Eating Disorder Examination-Questionnaire [EDE-Q]-Restraint, Three-Factor Flexible-Restraint and Rigid-Restraint) were administered at pretreatment and after 2 months of treatment. Regression models examined whether changes at 2-months in the restraint scales mediated the effects of treatment (CBT versus BWL) on binge eating and weight-loss outcomes at post-treatment. RESULTS CBT and BWL had similar binge-eating outcomes and similar changes in EDE-Q-restraint and flexible-restraint. BWL had greater 2-month increases in rigid-restraint and greater weight-loss at posttreatment than CBT, with results suggesting 2-month changes in rigid-restraint mediated the greater difference (>7 pounds) in weight-loss. The observed mediation effect of 2.92 suggests 39% of total treatment-effect on weight-loss was mediated through 2-month increases in rigid-restraint. DISCUSSION This secondary analysis within a trial comparing CBT and BWL for BED suggests early-change in rigid-restraint has a mediating effect of BWL on weight-loss. Findings indicate that BWL improves binge eating and challenge views that dietary-restraint might exacerbate binge eating in BED with obesity. Findings require confirmation using hypothesis-testing in future trials. TRIAL REGISTRATION Clinicaltrials.gov: NCT00537758 ("Treatment for Obesity and Binge Eating Disorder").

Abstract
Purpose: Binge eating disorder (BED) is a prevalent eating disorder. Many individuals with BED do not receive evidence-based care due to many barriers. This preliminary study evaluated the feasibility, acceptability, and potential efficacy of a manualized guided self-help (GSH) intervention with support in the form of a culturally adapted manual for a French-Canadian population.Method: Twenty-two women with overweight or obesity meeting the BED diagnostic criteria participated in an 8-week open trial. The GSH programme combined a self-help book and weekly support phone calls. Participants were assessed at baseline, at week 4, postintervention, and 12 weeks following its end. Feasibility was measured by attrition rates, participation, and satisfaction. Acceptability was measured by a questionnaire based on the Theoretical Framework of Acceptability. Potential efficacy outcomes were objective binge eating days, eating disorder symptomatology, depressive symptoms, and propensity to eat intuitively.Results: The GSH programme has proven feasible (4.5% attrition, 91% completion, 95.5% satisfaction) and acceptable. Potential efficacy results showed promising improvements on all outcomes (19% abstinence, 70.9% reduction in objective binge eating days).Conclusion: Although preliminary, this programme warrants further study as it may be an efficient and cost-effective way to deliver GSH for BED patients with accessibility barriers.

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
Ecological momentary assessment (EMA) of binge-eating symptoms has deepened our understanding of eating disorders. However, there has been a lack of attention on the psychometrics of EMA binge-eating symptom measures. This paper focused on evaluating the psychometric properties of a four-item binge-eating symptom measure, including multilevel factor structure, reliability, and convergent validity. Forty-nine adults with binge-eating disorder and/or food addiction completed baseline questionnaires and a 10-day EMA protocol. During EMA, participants completed assessments of eating episodes, including four binge-eating symptom items. Analyses included multilevel exploratory factor analysis, computation of omega and intraclass correlation coefficients, and multilevel structural equation models of associations between contextual factors and binge-eating symptoms. A one within-subject factor solution fit the data and showed good multilevel reliability and adequate within-subjects variability. EMA binge-eating symptoms were associated with baseline binge-eating measures as well as relevant EMA eating characteristics: including greater unhealthful food and drink intake; higher perceived taste of food; lower likelihood to be planned eating; and lower likelihood of eating to occur at work/school and other locations and greater likelihood to occur at restaurants compared to home. In conclusion, the study findings support the psychometrics of a 4-item one-factor EMA measure of binge-eating symptoms.

Abstract
Recent research suggests high rates of posttraumatic stress disorder (PTSD) and eating disorder (ED) comorbidity in women veterans. This study aims to expand the literature by examining associations between PTSD and ED diagnoses and symptoms in this population. We assessed probable PTSD diagnosis and symptom clusters (intrusion, avoidance, arousal and reactivity, and negative alterations in cognition and mood [NACM]), as well as probable Binge Eating Disorder (BED) diagnosis and ED subscales (dietary restraint, shape/weight overvaluation, and body dissatisfaction) in a sample of women veterans (N = 371). We investigated significance at the standard p < .05, and the Bonferroni-corrected p < .005 cut-off to adjust for experiment-wise error. Overall, we found that probable PTSD was associated with provisional BED (p < .001) using logistic regression at both cut-offs. Probable PTSD was associated with all ED subscales (all p's < 0.003) using linear regression models also at both cut-offs. Provisional BED was associated with NACM at p < .05 (p = .046), though it did not meet significance at our conservative cut-off. NACM was also associated with shape/weight overvaluation (p = .02) and a global ED score (p = .01) at p < .05, but not at our conservative cut-off; arousal was associated with shape/weight overvaluation (p = .04) and the global ED score (p = .02) at p < .05, but not at our conservative cut-off. Our findings may further guide how ED-related topics can be integrated in PTSD treatment for women veterans with comorbid PTSD and ED.

Abstract
Eating disorders are severe and often chronic mental illnesses that are associated with high impairment and mortality rates. Recent estimates suggest that eating disorder prevalence rates are on the rise, indicating an increased need for accurate assessment and detection. The current review provides an overview of transdiagnostic eating disorder assessments, including interview, self-report, health and primary care screeners, and technology-based and objective assessments. We focused on assessments that are transdiagnostic in nature and exhibit high impact in the field. We provide recommendations for how these assessments should be used in research and clinical settings. We also discuss considerations that are crucial for assessment, including the use of a categorical versus dimensional diagnostic framework, assessment of eating disorders in related fields (i.e., anxiety and depression), and measurement-based care for eating disorders. Finally, we provide suggestions for future research, including the need for more research on short transdiagnostic screeners for use in health care settings, standardized assessments for ecological momentary assessment, development of state-based assessment of eating disorder symptoms, and consideration of assessment across multiple timescales.

Abstract
PURPOSE Very few data exist on the association between metabolic dysfunction-associated steatotic liver disease (MASLD) and eating disorders. The study aimed to evaluate the presence of binge eating disorder (BED), in MASLD subjects. METHODS Demographic, clinical investigation, anthropometric measurements and laboratory were collected in 129 patients with MASLD (34.1% males; age, 53.7 years; BMI, 34.4 kg/m2) addressed by general practitioners to a hospital-based unit of metabolic disorders. The risk of binge eating was tested by the binge eating scale (BES); values in the range 17-26 were considered "possible" BED, values > 26 were considered "probable" BED. Hepatic steatosis and fibrosis were tested by surrogate biomarkers and imaging (transient elastography). Calorie intake and lifestyle were self-assessed by questionnaires. RESULTS Possible BED was present in 17.8% of cases, probable BED in another 7.6%, and were neither associated with gender, obesity class, diabetes, features of metabolic syndrome, nor with presence and severity of hepatic steatosis and fibrosis. Also steatosis grade by CAP and fibrosis stage by liver stiffness did not correlate with BES. However, an association was present between the daily caloric intake and "possible" BED (odds ratio, 1.14; 95% confidence interval, 1.05-1.24; "probable" BED, 1.21; 1.07-1.37), after adjustment for confounders. CONCLUSION Binge eating, as scored by BES, is present in a significant proportion of MASLD cases screened for metabolic disorders in a specialized center. It may impact behavioral treatment, reducing the chance of weight loss without systematic psychological support. LEVEL OF EVIDENCE Level III, cohort analytic study.

Abstract
OBJECTIVE Certain treatments have demonstrated acute efficacy for binge-eating disorder (BED) but many patients who receive "evidence-based" interventions do not derive sufficient benefit. Given the dearth of controlled research examining treatments for patients who fail to respond to initial interventions, this study tested the efficacy of cognitive-behavioral therapy (CBT) for patients with BED who do not respond to initial acute treatments. METHODS Prospective randomized double-blind placebo-controlled single-site trial, conducted August 2017-December 2021, tested 16-weeks of therapist-led CBT for non-responders to initial treatment (naltrexone/bupropion and/or behavioral therapy) for BED with obesity. Thirty-one patients (mean age 46.3 years, 77.4% women, 80.6% White, mean BMI 38.99 kg/m2 ) who were non-responders to initial acute treatments were randomized to CBT (N = 18) or no-CBT (N = 13), in addition to continuing double-blinded pharmacotherapy. Independent assessments were performed at baseline, throughout treatment, and posttreatment; 83.9% completed posttreatment assessments. RESULTS Intention-to-treat remission rates were significantly higher for CBT (61.1%; N = 11/18) than no-CBT (7.7%; N = 1/13). Mixed models of binge-eating frequency (assessed using complementary methods) converged revealing a significant interaction between CBT and time and a significant main effect of CBT. Binge-eating frequency decreased significantly with CBT but did not change significantly with no-CBT. Since only four patients received behavioral treatment during the acute treatments, we performed "sensitivity-type" analyses restricted to the 27 patients who received pharmacotherapy during the acute treatment and found the same pattern of findings for CBT versus no-CBT. CONCLUSIONS Adult patients with BED who fail to respond to initial pharmacological treatments should be offered CBT. PUBLIC SIGNIFICANCE Even with leading evidence-based treatments for binge-eating disorder, many patients do not derive sufficient benefit. Almost no controlled research has examined treatments for patients who fail to respond to initial interventions. This study found that that cognitive-behavioral therapy was effective for patients with binge-eating disorder who did not respond to initial interventions, with 61% achieving abstinence.

Schell SE, Racine SE. Reconsidering the role of interpersonal stress in eating pathology: Sensitivity to rejection might be more important than actual experiences of peer stress. Appetite 2023; 187:106588. [PMID: 37148973 DOI: 10.1016/j.appet.2023.106588] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 04/30/2023] [Accepted: 05/03/2023] [Indexed: 05/08/2023]
Abstract
Rejection sensitivity (i.e., the tendency to anxiously expect, readily perceive, and overreact to real or perceived rejection) is theorized to play a role in the onset and maintenance of disordered eating. Although rejection sensitivity has repeatedly been associated with eating pathology in clinical and community samples, the pathways through which this psychological trait influences eating pathology have been not fully established. The current study investigated peer-related stress, which can be influenced by rejection sensitivity and is associated with eating pathology, as a mechanism linking these constructs. In two samples of women - 189 first-year undergraduate students and 77 community women with binge eating - we examined whether rejection sensitivity was indirectly associated with binge eating and weight/shape concerns via ostracism and peer victimization, both cross-sectionally and longitudinally. Our hypotheses were not supported: there were no indirect associations between rejection sensitivity and eating pathology via interpersonal stress in either sample. However, we did find that rejection sensitivity was directly associated with weight/shape concerns in both samples and with binge eating in the clinical sample in cross-sectional (but not longitudinal) analyses. Our findings suggest that the association between rejection sensitivity and disordered eating is not dependent on actual experiences of interpersonal stress. That is, simply anticipating or perceiving rejection may be sufficient to play a role in eating pathology. As such, interventions targeting rejection sensitivity may be helpful in the treatment of eating pathology.

Abstract
This study examined the dimensional structure of the German Eating Disorder Examination-Questionnaire (EDE-Q) in clinical groups of women with Anorexia Nervosa (AN; N = 821), Bulimia Nervosa (BN; N = 573), and Binge-Eating Disorder (BED; N = 359) using Exploratory Graph Analyses (EGA). The EGA yielded a 12-item-four-dimension structure for the AN group (subscales "Restraint", "Body Dissatisfaction", "Preoccupation", "Importance"), a 20-item-five-dimension structure for the BN group (subscales "Restraint", "Body Dissatisfaction", "Eating Concern", "Preoccupation", "Importance"), and a 17-item-four-dimension structure for the BED group (subscales "Restraint", "Body Dissatisfaction", "Concern", "Importance"). This first investigation of the EDE-Q's dimensional structure using EGA suggests that the original factor model may be suboptimal for specific clinical ED samples and that alternative scoring should be considered when screening specific cohorts or evaluating the effects of interventions.

Abstract
BACKGROUND Impulsivity may be a process underlying binge-eating disorder (BED) psychopathology and its treatment. This study examined change in impulsivity during cognitive-behavioral therapy (CBT) and/or pharmacological treatment for BED and associations with treatment outcomes. METHODS In total, 108 patients with BED (NFEMALE = 84) in a randomized placebo-controlled clinical trial evaluating the efficacy of CBT and/or fluoxetine were assessed before treatment, monthly throughout treatment, at post-treatment (16 weeks), and at 12-month follow-up after completing treatment. Patients completed established measures of impulsivity, eating-disorder psychopathology, and depression, and were measured for height and weight [to calculate body mass index (BMI)] during repeated assessments by trained/monitored doctoral research-clinicians. Mixed-effects models using all available data examined changes in impulsivity and the association of rapid and overall changes in impulsivity on treatment outcomes. Exploratory analyses examined whether baseline impulsivity predicted/moderated outcomes. RESULTS Impulsivity declined significantly throughout treatment and follow-up across treatment groups. Rapid change in impulsivity and overall change in impulsivity during treatment were significantly associated with reductions in eating-disorder psychopathology, depression scores, and BMI during treatment and at post-treatment. Overall change in impulsivity during treatment was associated with subsequent reductions in depression scores at 12-month follow-up. Baseline impulsivity did not moderate/predict eating-disorder outcomes or BMI but did predict change in depression scores. CONCLUSIONS Rapid and overall reductions in impulsivity during treatment were associated with improvements in specific eating-disorder psychopathology and associated general outcomes. These effects were found for both CBT and pharmacological treatment for BED. Change in impulsivity may be an important process prospectively related to treatment outcome.

Abstract
BACKGROUND Suicide is one of the most commonly reported causes of death in individuals with eating disorders. However, the mechanisms underlying the suicide and disordered eating link are largely unknown, and current assessments are still unable to accurately predict future suicidal thoughts and behaviors. The purpose of this study is to test the utility of two promising proximal risk factors, sleep quality and agitation, in predicting suicidal ideation in a sample of individuals with elevated suicidal thoughts and behaviors, namely those with eating disorders. METHODS Women (N = 97) receiving treatment at an eating disorder treatment center completed weekly questionnaires assessing suicidal ideation, agitation, and sleep. General linear mixed models examined whether agitation and/or sleep quality were concurrently or prospectively associated with suicidal ideation across 12 weeks of treatment. RESULTS There was a significant interaction between within-person agitation and sleep quality on suicidal ideation [B(s.e.) = -0.02(0.01), p < 0.05], such that on weeks when an individual experienced both higher than their average agitation and lower than their average sleep quality, they also experienced their highest levels of suicidal ideation. However, neither agitation nor sleep quality prospectively predicted suicidal ideation. CONCLUSIONS This study was the first to examine dynamic associations between interpersonal constructs and suicidal ideation in individuals with eating disorders. Results suggest that ongoing assessment for overarousal symptoms, such as agitation and poor sleep quality, in individuals with eating disorders may be warranted in order to manage suicidal ideation among this vulnerable population.

Abstract
OBJECTIVE To compare individuals who have experienced binge-eating disorder (BED) and anorexia nervosa (AN) (BED AN+) to those who have experienced BED and not AN (BED AN-). METHOD Participants (N = 898) met criteria for lifetime BED and reported current binge eating. Approximately 14% had a lifetime diagnosis of AN. Analyses compared BED AN+ and BED AN- on sociodemographic variables and clinical history. RESULTS The presence of lifetime AN was associated with more severe eating disorder symptoms, including earlier onset, more frequent, more chronic, and more types of eating disorder behaviors over the lifetime, as well as a higher lifetime prevalence of bulimia nervosa (BN). Participants with lifetime AN reported being more likely to have received treatments for BED or BN, had significantly lower minimum, current, and maximum BMIs, had more severe general anxiety, and were significantly more likely to be younger and female. In the full sample, the lifetime prevalence of unhealthy weight control behaviors was high and treatment utilization was low, despite an average 15-year history since symptom onset. Gastrointestinal disorders and comorbid anxiety, depression, and attention-deficit/hyperactivity disorder symptoms were prevalent. DISCUSSION Individuals fared poorly on a wide array of domains, yet those with lifetime AN fared considerably more poorly. All patients with BED should be screened for mental health and gastrointestinal comorbidities and offered referral and treatment options. PUBLIC SIGNIFICANCE Individuals experiencing binge-eating disorder have severe symptomology, but those who have experienced binge-eating disorder and anorexia nervosa fare even more poorly. Our study emphasizes that patients with binge-eating disorder would benefit from being screened for mental health and gastrointestinal comorbidities, and clinicians should consider history of unhealthy weight control behaviors to inform treatment and relapse prevention.

Abstract
OBJECTIVE This study evaluated the severity ratings for anorexia nervosa (AN) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and an alternative severity rating based on overvaluation of weight/shape, on a range of psychological and biological variables. METHOD A sample of 312 treatment-seeking patients with AN (mean age = 25.3, SD = 7.6; mean BMI = 16.8 kg/m2 , SD = 2.4) were categorised using both DSM-5 severity levels (mild/moderate/severe/extreme) and weight/shape (low/high) overvaluation. The severity categories were compared on a range of psychological (e.g., eating psychopathology) and biological (e.g., sodium) variables. RESULTS Results showed that the overvaluation of weight/shape appeared better at indexing the level of severity in psychological variables among patients with AN compared to the DSM-5 severity rating with moderate to large effect sizes. Moreover, the DSM-5 mild and moderate severity groups experienced significantly higher eating and general psychopathology than the severe and extreme groups. Finally, neither the DSM-5 nor the weight/shape severity groups differed on any of the biological variables. CONCLUSIONS This study provided no support for the DSM-5 severity rating for AN, while initial support was found for the weight/shape overvaluation approach in indexing psychological but not biological correlates.

Abstract
Cue-induced food cravings are strong desires directed toward specific foods, usually ones with high caloric content, and can lead to overeating. However, although food cravings vary according to individual preferences for specific high-calorie food subtypes, a structured library of food craving-inducing pictures including multiple categories of high-calorie foods does not yet exist. Here, we developed and validated a picture library of Chinese foods (PLCF) consisting of five subtypes of high-calorie foods (i.e., sweets, starches, salty foods, fatty foods, and sugary drinks) to allow for more nuanced future investigations in food craving research, particularly in Chinese cultural contexts. We collected 100 food images representing these five subtypes, with four food items per subtype depicted in five high-resolution photographs each. We recruited 241 individuals with overweight or obesity to rate the food pictures based on craving, familiarity, valence, and arousal dimensions. Of these participants, 213 reported the severity of problematic eating behaviors as a clinical characteristic. Under the condition of mixing multiple subtypes of high-calorie foods, we did not observe significant differences in craving ratings for high- and low-calorie food images (p tukey > 0.05). Then, we compared each subtype of high-calorie food images to low-calorie ones, and found craving ratings were greater for the images of salty foods and sugary drinks (ps < 0.05). Furthermore, we conducted a subgroup analysis of individuals according to whether they did or did not meet the criteria for food addiction (FA) and found that greater cravings induced by the images of high-calorie food subtypes (i.e., salty foods and sugary drinks) only appeared in the subgroup that met the FA criteria. The results show that the PLCF is practical for investigating food cravings.

Abstract
OBJECTIVE Binge-eating disorder, the most prevalent eating disorder, is a serious public health problem associated with obesity, psychiatric and medical comorbidities, and functional impairments. Binge-eating disorder remains underrecognized and infrequently treated, and few evidence-based treatments exist. The authors tested the effectiveness of naltrexone-bupropion and behavioral weight loss therapy (BWL), alone and combined, for binge-eating disorder comorbid with obesity. METHODS In a randomized double-blind placebo-controlled trial conducted from February 2017 to February 2021, using a 2×2 balanced factorial design, 136 patients with binge-eating disorder (81.6% women; mean age, 46.5 years; mean BMI, 37.1) were randomized to one of four 16-week treatments: placebo (N=34), naltrexone-bupropion (N=32), BWL+placebo (N=35), or BWL+naltrexone-bupropion (N=35). Overall, 81.7% of participants completed independent posttreatment assessments. RESULTS Intention-to-treat binge-eating remission rates were 17.7% in the placebo group, 31.3% in the naltrexone-bupropion group, 37.1% in the BWL+placebo group, and 57.1% in the BWL+naltrexone-bupropion group. Logistic regression of binge-eating remission revealed that BWL was significantly superior to no BWL, and that naltrexone-bupropion was significantly superior to placebo, but there was no significant interaction between BWL and medication. Mixed models of complementary measures of binge-eating frequency also indicated that BWL was significantly superior to no BWL. The rates of participants attaining 5% weight loss were 11.8% in the placebo group, 18.8% in the naltrexone-bupropion group, 31.4% in the BWL+placebo group, and 38.2% in the BWL+naltrexone-bupropion group. Logistic regression of 5% weight loss and mixed models of percent weight loss both revealed that BWL was significantly superior to no BWL. Mixed models revealed significantly greater improvements for BWL than no BWL on secondary measures (eating disorder psychopathology, depression, eating behaviors, and cholesterol and HbA1c levels). CONCLUSIONS BWL and naltrexone-bupropion were associated with significant improvements in binge-eating disorder, with a consistent pattern of BWL being superior to no BWL.

Abstract
OBJECTIVE As network models of eating disorder (ED) psychopathology become increasingly popular in modeling symptom interconnectedness and identifying potential treatment targets, it is necessary to contextualize their performance against other methods of modeling ED psychopathology and to evaluate potential ways to optimize and capitalize on their use. To accomplish these goals, we used generalized network psychometrics to estimate and compare latent variable models and network models, as well as hybrid models. METHOD We tested the structure of the Eating Pathology Symptoms Inventory (EPSI) and Eating Disorder Examination-Questionnaire (EDE-Q) in Recovery Record, Inc. mobile phone application users (N = 6856). RESULTS Although all models fit well, results favored a hybrid latent variable and network framework, which showed that ED symptoms fit best when modeled as higher-order constructs, rather than direct symptom-to-symptom connections, and when the relationships between those constructs are described as a network. Hybrid models in which latent factors were modeled as nodes within a network showed that EPSI Purging, Binge Eating, Cognitive Restraint, Body Dissatisfaction, and Excessive Exercise had high importance in the network. EDE-Q Eating Concern and Shape Concern were also important nodes. Results showed that the EPSI network was highly stable and replicable, whereas the EDE-Q network was not. DISCUSSION Integrating latent variable and network model frameworks enables tests of centrality to identify important latent variables, such as purging, that may promote the spread of ED psychopathology throughout a network, allowing for the identification of future treatment targets.

Abstract
Eco-concern, the distress experienced relating to climate change, is associated with mental health, yet no study has examined disordered eating related to eco-concern. This study developed and validated a 10-item scale assessing Eating-Related Eco-Concern (EREC). Participants (n = 224) completed the EREC, Climate Change Worry Scale (CCWS), and Eating Disorder Examination-Questionnaire (EDE-Q). Construct validity, convergent validity, and internal consistency were evaluated. Sex differences in EREC were evaluated using t-tests. Associations among the EREC, CCWS, and EDE-Q were evaluated using linear regression models. Sensitivity analyses were conducted in individuals below EDE-Q global score clinical cut-offs. Factor analysis suggested that all items loaded adequately onto one factor. Pearson's correlation and Bland-Altman analyses suggested strong correlation and acceptable agreement between the EREC and CCWS (r = 0.57), but weak correlation and low agreement with the EDE-Q global score (r = 0.14). The EREC had acceptable internal consistency (α = 0.88). No sex difference was observed in the EREC in the full sample; females had a significantly higher mean score than males in sensitivity analysis. The EREC was significantly positively associated with the CCWS and EDE-Q global and shape concern scores, but not in sensitivity analysis. The EREC is a brief, validated scale that can be useful to screen for eating-related eco-concern.

Abstract
BACKGROUND The overlap in prevalence between type 2 diabetes and binge eating disorder is substantial, with adverse physical and mental health consequences. Little is known about patients' efforts at managing these two conditions simultaneously. The research objective was to explore patients' experiences managing co-existing type 2 diabetes or prediabetes and binge eating disorder. METHODS This is a qualitative descriptive study using semi-structured interviews. Participants included 21 women with type 2 diabetes or prediabetes (90% non-Hispanic White; mean age 49 ± 14.8 years, mean BMI 43.8 ± 8.4; 48% with type 2 diabetes and mean HbA1c was 8.4%). Interviews were analyzed using thematic analysis and NVivo software. RESULTS Qualitative analysis revealed that participants reported binge episodes frequently started in childhood or adolescence and went undiagnosed for decades; notably, they recalled that diabetes diagnosis preceded the binge eating disorder diagnosis. They also described trying to lose weight throughout their lives and how feelings of deprivation, shame, and failure exacerbated binge eating. Participants further reported how binge eating made diabetes self-care and outcomes worse. Finally, participants observed that when binge eating disorder treatment and diabetes management were synergistically integrated, they experienced improvements in both binge eating and glycemic outcomes. This integration included reframing negative thoughts surrounding binge eating disorder and diabetes self-management and increasing their understanding of how the two disorders were inter-related. CONCLUSION Findings highlight the importance of increasing healthcare providers' awareness of and screening for binge eating disorder in the treatment of diabetes and inform specific integrated interventions that address both diagnoses. From this study where we interviewed 21 women with binge eating disorder (BED) and type 2 diabetes/prediabetes, we learned how binge eating impacted diabetes management and how diabetes impacted BED. Most participants reported receiving the diabetes diagnosis before being diagnosed with BED despite the earlier onset of binge eating, pointing to the need for BED screening. Participants described trying to lose weight throughout their lives and reported feelings of failure and shame, which made binge eating worse. Binge eating made diabetes management harder, but when diabetes and BED treatment were aligned, participants experienced improvements in binge symptoms and diabetes outcomes.

[PMID: 35757216 PMCID: PMC9218174 DOI: 10.3389/fpsyt.2022.913067] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 05/10/2022] [Indexed: 12/03/2022] Open
Abstract
Introduction Depression is a prevalent mental health condition worldwide and in Malaysia. Depression among adolescents has been steadily increasing. Self-esteem has been known to be associated with depression. It has been postulated that a poor lifestyle among adolescents is associated with depression. This paper aims to study the correlation of self-esteem, lifestyle (eating behavior, physical activity, and internet usage) with depression among Malaysian youth. Methodology This is a cross-sectional study among secondary school children from 5 random schools in an urban city of Kuala Lumpur, Malaysia. Those with intellectual disability and/or difficulty to comprehend Malay language, and without parental consent and assent, were excluded. Students from randomly selected classes aged 13-year-old to 17-year-old were invited to fill in these questionnaires: Socio-demographic Questionnaire, Rosenberg Self-esteem Questionnaire, Physical Activity Questionnaire (PAQ-A), Eating Disorder Examination Questionnaires (EDE-Q), Internet Addiction Test Scale (IAT), and Children's Depression Inventory (CDI). Result 461 students participated in the study. 21.5% of the participating students were found to have depression (n = 99). Younger age and Chinese race showed significant association with adolescent depression with a p-value of 0.032 and 0.017 respectively. Other significant correlations with depression were self-esteem (p = 0.013), disordered eating (p = 0.000), lower physical activity (p = 0.014) and problematic internet usage (p = 0.000). Discussion The prevalence of depression among adolescents in this study (21.5%) is in line with previous prevalence studies in Malaysia. Self-esteem is postulated to be a moderating factor for depression hence explaining the significant association. A sedentary lifestyle may increase the risk of developing depression, The causal relationship between problematic internet usage and depression is complex and difficult to establish. This is similar to the relationship between problematic eating behavior and depression as well. Conclusion There is still a need to explore the causal relationship between lifestyle factors and depression among youth. Despite that, the results from this paper have accentuated the gravity of the importance of a healthy lifestyle among adolescents. An appropriate preventive measure is governmental strategies and policies aiming at improving a healthier lifestyle in this age group.

Abstract
Background Although binge eating disorder (BED) is the most common eating pathology and carries a high mental and physical burden, access to specialized treatment is limited due to patient-related barriers and insufficient healthcare resources. Integrating web-based self-help programs into clinical care for BED may address this treatment gap by making evidence-based eating disorder interventions more accessible. Methods A two-armed randomized controlled trial will be conducted to evaluate the effectiveness of a web-based self-help intervention for BED in routine care settings. Patients aged 18-65 years fulfilling the diagnostic criteria for BED (N = 152) will be randomly allocated to (1) an intervention group receiving a 12-week web-based self-help program or (2) a waitlist control group with delayed access to the intervention. The primary outcome will be the number of binge eating episodes. Secondary outcomes include global eating pathology, functional impairments, work capacity, well-being, comorbid psychopathology, self-esteem, and emotion regulation abilities. Measurements will be conducted at baseline (study entrance), 6 weeks after baseline (mid-treatment), and 12 weeks after baseline (post-treatment). To capture outcomes and treatment mechanisms in real-time, traditional self-reports will be combined with weekly symptom monitoring and ecological momentary assessment. Discussion Evaluating the effectiveness of web-based interventions is essential to overcome the treatment gap for patients with BED. When adequately integrated into standard care, these programs have the potential to alleviate the high burden of BED for individuals, their families, and society.

Abstract
OBJECTIVE The aim of this fixed-dose study was to evaluate the efficacy and safety of dasotraline in the treatment of patients with binge-eating disorder (BED). METHODS Patients meeting Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria for BED were randomized to 12 weeks of double-blind treatment with fixed doses of dasotraline (4 and 6 mg/d), or placebo. The primary efficacy endpoint was change in number of binge-eating (BE) days per week at week 12. Secondary efficacy endpoints included week 12 change on the BE CGI-Severity Scale (BE-CGI-S) and the Yale-Brown Obsessive-Compulsive Scale Modified for BE (YBOCS-BE). RESULTS At week 12, treatment with dasotraline was associated with significant improvement in number of BE days per week on the dose of 6 mg/d (N = 162) vs placebo (N = 162; -3.47 vs -2.92; P = .0045), but not 4 mg/d (N = 161; -3.21). Improvement vs placebo was observed for dasotraline 6 and 4 mg/d, respectively, on the BE-CGI-S (effect size [ES]: 0.37 and 0.27) and on the YBOCS-BE total score (ES: 0.43 and 0.29). The most common adverse events on dasotraline were insomnia, dry mouth, headache, decreased appetite, nausea, and anxiety. Changes in blood pressure and pulse were minimal. CONCLUSION Treatment with dasotraline 6 mg/d (but not 4 mg/d) was associated with significantly greater reduction in BE days per week. Both doses of dasotraline were generally safe and well-tolerated and resulted in global improvement on the BE-CGI-S, as well as improvement in BE related obsessional thoughts and compulsive behaviors on the YBOCS-BE. These results confirm the findings of a previous flexible dose study.

Abstract
BACKGROUND Eating disorders are amongst the deadliest of all mental disorders, however detection and early intervention rates remain extremely low. Current standardised screening questionnaires can be arduous or confronting and are ill-validated for online use, despite a universal shift to digital healthcare. The present study describes the development and pilot validation of a novel digital screening tool (the InsideOut Institute-Screener) for high risk and early stage eating disorders to drive early intervention and reduced morbidity. METHODS We utilised a mixed cross-sectional and repeated measures longitudinal survey research design to assess symptom severity and recognised parameters of statistical validity. Participants were recruited through social media and traditional advertising, and through MTurk. An Eating Disorders Examination Questionnaire (EDE-Q) global score of 2.3 and assessment of eating disorder behaviours was used to determine probable ED. 1346 participants aged 14-74 (mean [SE] age 26.60 [11.14] years; 73.8% female, 22.6% male) completed the survey battery. 19% were randomised to two-week follow-up for reliability analysis. RESULTS Strong positive correlations between the IOI-S and both the EDE-Q global (rs = .88) and SCOFF (rs = .75) total score were found, providing support for the concurrent validity of the scale. Inter-item correlations were moderate to strong (rs = .46-.73). Correlations between the IOI-S and two measures of social desirability diverged, providing support for the discriminant validity of the scale. The IOI-S demonstrated high internal consistency (α = .908, ω = .910) and excellent two-week test-retest reliability (.968, 95% CI 0.959-0.975; p ≤ 0.1). The IOI-S accurately distinguished probable eating disorders (sensitivity = 82.8%, specificity = 89.7% [AUC = .944], LR+ = 8.04, LR- = 0.19) and two stepped levels of risk. CONCLUSIONS AND RELEVANCE The present study provides excellent initial support for the psychometric validity of the InsideOut Institute digital screening tool, which has the potential to streamline early intervention in the hopes of reducing current high morbidity and mortality. Further validation should be undertaken in known clinical populations. Eating disorders are amongst the deadliest of all mental disorders, however detection and early intervention rates remain extremely low. The present study describes the initial psychometric validation of a novel digital screening tool (the InsideOut Institute Screener) for high risk and early stage eating disorders, for self-referral and/or use in primary care. 1346 participants aged 14-74 of all genders completed a survey battery designed to assess common parameters of statistical validity. Strong support was found for the screener's ability to accurately measure eating disorder risk and symptomatology. The screener was highly positively correlated with a well known and extensively validated long form self-report questionnaire for eating disorder symptomatology. This study is a pilot validation and the genesis of a project that aims ultimately to drive early intervention leading to reduced morbidity and mortality rates in this illness group.

Abstract
OBJECTIVE Eating disorders commonly co-occur with gastrointestinal problems. This case-control study aimed to (a) document the prevalence of disorders of gut-brain interaction (DGBI) in eating disorders, (b) examine the specific impact of disordered eating behaviors on the risk of DGBI, and (c) explore the impact of current eating disorder psychopathology on DGBI. METHOD We included 765 cases with eating disorders and 1,240 controls. DGBI were assessed via the ROME III questionnaire. Prevalences of DGBI were calculated across eating disorder diagnoses (anorexia nervosa, bulimia nervosa, and multiple eating disorders) and in controls. The association between disordered eating behaviors and DGBI was examined using logistic regression models. Lastly, we compared the total number of DGBI in individuals with high versus low current eating disorder symptoms. RESULTS A large majority (88.2-95.5%) of individuals with eating disorders reported at least one DGBI and 34.8-48.7% reported three or more DGBI. Of the DGBI categories, functional bowel disorders were the most commonly endorsed category, and of the individual DGBI, irritable bowel syndrome was the most frequently reported (43.9-58.8%). All investigated disordered eating behaviors showed a positive association with most DGBI categories. Finally, individuals reporting high current eating disorder symptoms reported higher mean number of DGBI (3.03-3.34) than those with low current symptoms (1.60-1.84). DISCUSSION The directionality and mechanisms underlying the nature of the relationship between gastrointestinal and eating disorder symptoms is worthy of further study and clinicians should adopt an integrated approach by attending to both gastrointestinal and eating disorder symptoms in their patients.

Abstract
BACKGROUND Psychiatric comorbidity is common in binge-eating disorder (BED) but effects on treatment outcomes are unknown. The current study aimed to determine whether psychiatric comorbidity predicted or moderated BED treatment outcomes. METHODS In total, 636 adults with BED in randomized-controlled trials (RCTs) were assessed prior, throughout, and posttreatment by doctoral research-clinicians using reliably-administered semi-structured interviews, self-report measures, and measured weight. Data were aggregated from RCTs testing cognitive-behavioral therapy, behavioral weight loss, multi-modal (combined pharmacological plus cognitive-behavioral/behavioral), and/or control conditions. Intent-to-treat analyses (all available data) tested comorbidity (mood, anxiety, 'any disorder' separately) as predictors and moderators of outcomes. Mixed-effects models tested comorbidity effects on binge-eating frequency, global eating-disorder psychopathology, and weight. Generalized estimating equation models tested binge-eating remission (zero binge-eating episodes during the past month; missing data imputed as failure). RESULTS Overall, 41% of patients had current psychiatric comorbidity; 22% had mood and 23% had anxiety disorders. Psychiatric comorbidity did not significantly moderate the outcomes of specific treatments. Psychiatric comorbidity predicted worse eating-disorder psychopathology and higher binge-eating frequency across all treatments and timepoints. Patients with mood comorbidity were significantly less likely to remit than those without mood disorders (30% v. 41%). Psychiatric comorbidity neither predicted nor moderated weight loss. CONCLUSIONS Psychiatric comorbidity was associated with more severe BED psychopathology throughout treatment but did not moderate outcomes. Findings highlight the need to improve treatments for BED with psychiatric comorbidities but challenge perspectives that combining existing psychological and pharmacological interventions is warranted. Treatment research must identify more effective interventions for BED overall and for patients with comorbidities.

Abstract
PURPOSE To evaluate the long-term effectiveness of a web-based therapist-delivered cognitive behavioral therapy (CBT) for patients with eating disorders (ED). METHODS We used follow-up data from a randomized controlled trial that evaluated a web-based CBT on ED psychopathology and related health, compared to a waiting list control (WL) condition. As participants of the WL condition started the intervention after their waiting period, follow-up data included participants from both groups. The primary outcome was change from baseline, at 3, 6, and 12-month intervals in ED psychopathology, analyzed using mixed models for repeated measures. Secondary outcomes included body dissatisfaction, BMI, physical health, mental health, self-esteem, quality of life, and social functioning. RESULTS The population comprised 212 participants in total, in three subgroups: bulimia nervosa (BN; n = 44), binge eating disorder (BED; n = 83), and ED not otherwise specified (EDNOS; n = 85). Treatment effects were sustained during follow-up, with generally large effect sizes for the reduction of ED psychopathology and body dissatisfaction, and small to moderate effect sizes for physical and mental health, self-esteem, social functioning, and quality of life. Most effects were found for all three subgroups, except for long-term improvements in self-esteem and quality of life among participants with BN and EDNOS. CONCLUSION This study showed long-term sustainability of treatment effects up to 1-year post-treatment of a web-based therapist-delivered CBT for patients with various ED.

Abstract
OBJECTIVE While there is evidence to support the use of group dialectical behavior therapy (DBT) in the treatment of binge-eating disorder (BED), treatment is relatively long compared with other evidence-based treatments. This study explored the effectiveness of brief DBT groups for BED, delivered in a routine community setting. METHOD Eighty-four adults with BED entered 10-week DBT group treatment in a community eating disorders service. In total, 12 groups were conducted. Patients completed measures of eating disorder pathology, anxiety, depression, and emotional eating at the start and end of treatment, and at 1-month follow-up. Frequency of weekly binges was recorded. RESULTS Outcomes were similar to those of longer versions of DBT, with an attrition rate of 26%, and significant reductions in eating disorder psychopathology and emotional eating by the end of treatment and at follow-up. Over 50% of patients were abstinent from binge eating by Session 4. DISCUSSION Group DBT delivered in a 10-session format is clinically equivalent to longer versions of the same treatment. Future research is required to explore patterns of change and to demonstrate replicability under controlled conditions, but these findings are promising for the efficient delivery of effective treatment and reducing waiting times.

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
Weight self-stigma, in which individuals internalize stigmatizing messages about weight, is a prevalent problem that contributes to poor quality of life and health. This pilot randomized controlled trial evaluated acceptance and commitment therapy (ACT) guided self-help using The Diet Trap for 55 overweight/obese adults high in weight self-stigma. Participants were randomized to the ACT self-help book plus phone coaching (GSH-P; n = 17), self-help book plus email prompts only (GSH-E; n = 20), or a waitlist condition (n = 18), with online self-report assessments at baseline and posttreatment (8 weeks later). Participants reported high satisfaction ratings and engagement with the ACT self-help book, with no differences between GSH-P and GSH-E. Both GSH-P and GSH-E improved weight self-stigma relative to waitlist with large effect sizes. There were mixed findings for health outcomes. The GSH-P condition improved more on healthy eating behaviors and general physical activity, but neither ACT condition improved more than waitlist on self-reported body mass index, emotional eating, and a second measure of physical activity. Results suggest an ACT self-help book with email prompts can reduce weight self-stigma and potentially improve some health behavior outcomes. Phone coaching may provide additional benefits for generalizing ACT to diet and physical activity.

[PMID: 33218742 DOI: 10.1016/j.clinthera.2020.10.010] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 10/27/2020] [Accepted: 10/28/2020] [Indexed: 11/28/2022]
Abstract
PURPOSE Binge-eating disorder (BED), the most prevalent eating disorder, is associated strongly with obesity and functional impairments. Few evidence-based treatments for BED exist; a pharmacotherapy effective in reducing both binge eating and weight needs to be identified. This placebo-controlled double-blind pilot RCT evaluated the acute effects of naltrexone + bupropion (NB) on BED with obesity and examined the longer-term effects through 6-month follow-up after the discontinuation of medication. METHODS Twenty-two adult patients with BED were randomized to receive 12 weeks of double-blind treatment with fixed-dose NB (naltrexone + bupropion XL 50/300 mg) or placebo. Independent (blinded) researcher-clinicians evaluated patients at major outcome time points (baseline, posttreatment, and 6-month follow-up after the treatment period); patients were also evaluated for the tracking of course/tolerability throughout treatments and at 3-month follow-up. Primary outcomes were changes from baseline in binge-eating frequency and percentage weight. Secondary outcomes were changes in eating-disorder psychopathology and depression. FINDINGS A total of 22 patients were enrolled (86.4% women; mean age, 50.4 years), with 77.3% of patients completing treatments; completion rates (NB, 83.3%; placebo, 70.0%) and adverse events did not differ significantly between NB and placebo. Analyses revealed significant reductions from baseline in binge-eating, eating-disorder psychopathology, depression, and weight during treatment, but these changes with NB did not differ significantly from those with placebo. The percentage of patients who attained 3% weight loss was significantly greater with NB than with placebo (45.5% vs 0%); weight-loss and binge-eating reductions were significantly correlated in the group that received NB. At 6-month follow-up, outcomes remained improved relative to baseline, with no significant differences between NB and placebo. IMPLICATIONS The findings from this pilot RCT suggest that NB was well-tolerated in these patients with BED and comorbid obesity. Most outcomes were not statistically different between NB and placebo. A larger-scale, adequately powered RCT is needed for determining the efficacy of NB in the treatment of BED. ClinicalTrials.gov identifier: NCT02317744.

Abstract
OBJECTIVE Whilst there is evidence to support the use of group dialectical behavioral therapy (DBT) in the treatment of binge-eating disorder (BED), few studies have reported on its effectiveness when delivered in routine clinical practice. This study addressed this gap by exploring the effectiveness of group DBT for BED when delivered in a community eating disorder service. METHOD Participants were 56 adults who presented with BED, and were offered a 20-week DBT group. Eight groups were conducted. Measures of eating disorder pathology, anxiety, depression and emotion regulation were completed at start and end of treatment, and one-month follow-up. RESULTS The attrition rate was 16.1%. Abstinence rates (no objective binges in the previous month) were approximately 60% at the end of treatment and 50% at follow-up. There were significant reductions in eating disorder psychopathology (but not in mood) by end of treatment and improvements were maintained at follow-up. DISCUSSION Group DBT is an acceptable and effective treatment for adults with BED when delivered in a routine community setting. Findings are broadly comparable with those from research trials. The lack of significant effect on mood suggests that DBT can be effective by teaching new emotion-regulation skills, rather than changing mood per se.

Abstract
OBJECTIVE There is preliminary evidence for an association between personality traits and binge eating disorder (BED) in obese patients. In addition, recent studies have shown impaired psychodynamic personality functioning in BED. However, these results are partly inconsistent. The goal of this study was to explore and evaluate personality traits and personality functioning in obese patients with BED or subthreshold BED. Moreover, we aimed to explore the additional value of combined assessment of personality traits and personality functioning. METHODS Treatment-seeking obese female patients with BED (n=129) or subthreshold BED (n=91) were compared with obese (n=107) and nonobese (n=90) female community controls in terms of personality traits (using the Temperament and Character Inventory) and personality functioning (using the Developmental Profile Inventory) in univariate and multivariate analyses. RESULTS Harm Avoidance was higher and Self-Directedness was lower in obese patients with BED or subthreshold BED compared with obese and nonobese community controls. In addition, obese patients with BED or subthreshold BED presented more maladaptive and less adaptive personality functioning than controls. Although univariate analyses did not find significant differences in personality traits or personality functioning between obese patients with BED and those with subthreshold BED, when both personality traits and personality functioning were combined in multivariate analysis (data from both the Temperament and Character Inventory and Developmental Profile Inventory), obese patients with BED showed greater vulnerabilities in personality traits and functioning than obese patients with subthreshold BED. CONCLUSIONS Obese patients with BED or subthreshold BED had specific impairments in personality traits and personality functioning. Combined assessment indicated that patients with BED had the most vulnerable personality profile of the 4 groups. The results support the added value of assessment of both personality traits and psychodynamic personality functioning, in line with the alternative Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) model for personality disorders.

Abstract
PURPOSE Numerous studies highlight the relevance of body image in the development and maintenance of overweight and obesity mostly using self-reported data. Given the importance of physiological assessment methods, the present study aimed at investigating vocally encoded emotional arousal as a correlate of body distress in women with overweight and obesity. METHODS Cognitions of women with overweight and obesity (OW; n = 22) as well as normal weight controls (NW; n = 22) were assessed by means of a thought-sampling procedure during a mirror exposure and a control condition. Fundamental frequency (f0) as a marker of vocally encoded emotional arousal as well as verbalized body-related cognitions were analyzed during this experimental task. RESULTS A stronger increase in f0 between the control and the mirror exposure condition was found in OW compared to NW. Furthermore, there were significant positive correlations between vocally encoded emotional arousal and various measures of body image. CONCLUSION The findings support the utility of vocally encoded emotional arousal as an objective physiological correlate of the evaluative dimension of body image in women with overweight and obesity. LEVEL OF EVIDENCE Level I, experimental study.

Abstract
OBJECTIVE Self-criticism has been proposed as a transdiagnostic predictor of disordered eating and nonsuicidal self-injury (NSSI). First, this study explored cross-sectional associations of multiple disordered eating behaviors, NSSI, and self-criticism. Second, it tested longitudinal relations of self-criticism with disordered eating and NSSI, adjusting for baseline levels of both behaviors. METHODS In Sub-study 1, undergraduates (N = 251, 79.5% female, Mage = 19.1 years) completed self-report measures of disordered eating, NSSI, and self-criticism at baseline and after 8 weeks. In Sub-study 2, community-based young adults with histories of disordered eating, NSSI, or both (N = 517, 88.8% female, Mage = 24.7 years) completed measures of disordered eating, NSSI, and self-criticism at baseline and after 4 weeks. All measures were completed online. RESULTS In Sub-study 1, both disordered eating and NSSI showed significant cross-sectional associations with self-criticism, and self-criticism was significantly related to binge eating, fasting, and NSSI at follow-up. In Sub-study 2, both behaviors again showed significant cross-sectional associations with self-criticism. Self-criticism showed significant longitudinal relations with fasting, purging, and excessive exercise. Longitudinal relations of self-criticism with NSSI varied across disordered eating behaviors. DISCUSSION NSSI showed cross-sectional associations with a range of disordered eating behaviors. Self-criticism reflects a common correlate of both disordered eating and NSSI. Evidence supported transdiagnostic longitudinal impact of self-criticism across multiple forms of disordered eating but provided more limited support for impacts on NSSI.

Abstract
OBJECTIVE Enhanced cognitive behavior therapy (CBT-E) is a transdiagnostic treatment suitable for the full range of eating disorders (EDs). Although the effectiveness of CBT(-E) is clear, it is not being used as widely in clinical practice as guidelines recommend. The aim of the present study was to compare the effectiveness of CBT-E with treatment as usual (TAU), which was largely based on CBT principles. METHOD We conducted a randomized controlled trial on a total of 143 adult patients with an ED who received either CBT-E or TAU. The primary outcome was recovery from the ED. Secondary outcome measures were levels of ED psychopathology, anxiety, and depressive symptoms. Self-esteem, perfectionism, and interpersonal problems were repeatedly measured to examine possible moderating effects. We explored differences in duration and intensity between conditions. RESULTS After 80 weeks, there were no differences between conditions in decrease in ED psychopathology, or symptoms of anxiety and depression. However, in the first six weeks of treatment there was a larger decrease in ED psychopathology in the CBT-E condition. Moreover, when the internationally most widely used definition of recovery was applied, the recovery rate at 20 weeks of CBT-E was significantly higher (57.7%) than of TAU (36.0%). At 80 weeks, this difference was no longer significant (CBT-E 60.9%; TAU 43.6%). Furthermore, CBT-E was more effective in improving self-esteem and was also the less intensive and shorter treatment. DISCUSSION With broader use of CBT-E, the efficiency, accessibility and effectivity (on self-esteem) of treatment for EDs could be improved.

Abstract
PURPOSE Severe obesity is difficult to treat, and non-surgical treatment is not supported by robust evidence. The aim of the present study was to establish the immediate and longer-term outcomes following "personalized" form of group cognitive behavioural therapy for obesity (CBT-OB)-a new treatment designed to address specific cognitive processes that have been associated with attrition, weight loss, and weight maintenance in previous studies. METHODS Sixty-seven adult patients with obesity (body mass index (BMI) ≥ 30 kg/m2) were recruited from consecutive referrals to an Italian National Health Service obesity clinic. Each patient was offered 22 group sessions of CBT-OB (14 in the 6-month weight-loss phase and 8 in the subsequent 12-month weight-maintenance phase). RESULTS 76.2% patients completed the treatment, with an average weight loss of 11.5% after 6 months (10% in the intention-to-treat analysis) and 9.9% (7.5% in the intention-to-treat analysis) after 18 months. Weight loss was associated with a significant reduction in cardiovascular risk factors, anxiety, depression, and eating disorder psychopathology, and an improvement in obesity-related quality of life. CONCLUSIONS These findings provide strong preliminary support for the use of CBT-OB for obesity in standard clinical settings, and justify its further evaluation in randomized controlled trials.

Abstract
One factor, believed to predict body dissatisfaction is an individual’s propensity to attend to certain classes of human body image stimuli relative to other classes. These attentional biases have been evaluated using a range of paradigms, including dot-probe, eye-tracking and free view visual search, which have yielded a range of – often contradictory – findings. This study is the first to employ a classic compound visual search task to investigate the relationship between body dissatisfaction and attentional biases to images of underweight and with-overweight female bodies. Seventy-one undergraduate females, varying their degree of body dissatisfaction and Body Mass Index (BMI), searched for a horizontal or vertical target line among tilted lines. A separate female body image was presented within close proximity to each line. On average, faster search times were obtained when the target line was paired with a uniquely underweight or with-overweight body relative to neutral (average weight only) trials indicating that body weight-related images can effectively guide search. This congruent search effect was stronger for individuals with high eating restraint (a behavioral manifestation of body image disturbance) when search involved a uniquely underweight body. By contrast, individuals with high BMIs searched for lines more rapidly when paired with with-overweight rather than underweight bodies, than did individuals with lower BMIs. For incongruent trials – in which a unique body was paired with a distractor rather than the target – search times were indistinguishable from neutral trials, indicating that the deviant bodies neither compulsorily “captured” attention nor reduced participants’ ability to disengage their attention from either underweight or with-overweight bodies. These results imply the existence of attentional strategies which reflect one’s current body and goal-directed eating behaviors.

Abstract
OBJECTIVE To test the validity and clinical utility of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) severity specifiers for binge-eating disorder (BED) in predicting treatment outcomes. METHOD Participants (N = 521) were patients in randomized controlled trials (RCTs) at 1 medical center testing treatments for BED; data were aggregated from RCTs testing cognitive-behavioral therapy (CBT), behavioral weight loss (BWL), and/or multimodal (i.e., CBT or BWL plus pharmacotherapy) treatment. Participants were categorized according to DSM-5 severity specifiers for BED: "mild" (n = 273; 52.5%), "moderate" (n = 182; 34.9%), and "severe/extreme" (n = 58; 11.1%). Participants had their weight and height measured and were assessed using established interviews and self-report measures at baseline, throughout treatment, and post treatment. RESULTS Mixed models revealed that severity category did not significantly predict treatment response. However, there were main effects of BED severity category: "Severe/extreme" BED had greater binge-eating frequency and had greater global eating-disorder psychopathology than did "mild" BED across all time points. "Severe/extreme" BED was less likely to have remission from binge eating than was "mild" BED. Weight loss and depression scores did not significantly differ by severity category. CONCLUSION In a large series of treatment-seeking individuals with BED aggregated across RCTs at 1 medical center testing psychological and pharmacological treatments for BED, DSM-5 severity specifiers for BED had limited validity and utility predicting response to treatments. Future research is needed to identify more robust severity indicators with clinical utility to inform future DSM revisions and clinical practice.

Abstract
OBJECTIVE This study examined whether sex predicted and/or moderated treatment outcomes among men and women who participated in binge-eating disorder (BED) randomized controlled trials (RCTs). METHOD Data were aggregated from RCTs performed at one medical center. RCTs tested cognitive-behavioral therapy, behavioral weight loss, multimodal treatment, and/or control conditions. Participants were 660 adults, both men (n = 170) and women (n = 490), with Diagnostic and Statistical Manual-fourth edition (DSM-IV)-defined BED. Doctoral-level research-clinicians assessed participants using structured interviews and established self-report measures of eating-disorder psychopathology and depression, and measured height and weight. Assessments occurred at baseline, throughout treatment, and at post-treatment. RESULTS Sex was not a significant moderator of any treatment outcomes. Mixed models revealed sex had a main effect: men had lower eating-disorder psychopathology and lost more weight than women over the course of treatment. DISCUSSION Both epidemiological and RCT studies report disparities in treatment-seeking between men and women with BED. Despite this, men have comparable or better treatment outcomes compared with women, including significantly greater weight loss. Thus, disseminating evidence-based BED treatments is promising for both men and women. Additional research is necessary, however, to understand treatment effects-including other predictors and moderators of outcomes-across diverse providers, treatment settings, and patient groups.

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 Zinc plays an important role in appetite regulation. L-Carnosine, an endogenous dipeptide, may also regulate eating behavior via its histaminergic and antiglutamatergic properties. Polaprezinc (zinc-L-carnosine complex) is a medication for gastric ulcers. A small case series reported successful treatment of binge eating with add-on polaprezinc. METHODS This was an open trial of add-on polaprezinc in patients with binge eating disorder (BED; n = 22) or bulimia nervosa (BN; n = 7) receiving antidepressants. A 4-week baseline period was followed by a 16-week polaprezinc treatment at 150 mg/d (containing 34 mg zinc and 116 mg L-carnosine) in addition to ongoing psychotropic medications. We also assessed their zinc status via a laboratory index and zinc deficiency-related symptoms. RESULTS At the study end, both conditions showed a significant reduction in the 4-week frequency of combined objective and subjective binge eating episodes, the 4-week frequency of days when at least 1 such episode occurred (only in BED), several aspects of eating disorder psychopathology (rated by the Eating Disorder Examination-Questionnaire), and comorbid depressive symptoms (rated by the 16-item Quick Inventory of Depressive Symptomatology [Self-Report]). Serum copper/zinc ratio decreased from 1.4 to 1.1 on average in both conditions. All patients had multiple zinc deficiency-related symptoms at baseline that substantially improved after polaprezinc treatment. Overall, the effectiveness of polaprezinc was greater in BED patients than in BN patients, with minor adverse effects. CONCLUSIONS These findings offer preliminary evidence for the effectiveness of polaprezinc in treating BED and BN and suggest the involvement of zinc deficiency in these conditions.

Dialectical behavior therapy adapted for binge eating compared to cognitive behavior therapy in obese adults with binge eating disorder: a controlled study. J Eat Disord 2020; 8:27. [PMID: 32528681 PMCID: PMC7285554 DOI: 10.1186/s40337-020-00299-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Accepted: 05/18/2020] [Indexed: 12/24/2022] Open
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
BACKGROUND Interpersonal psychotherapy (IPT) can be effective for both Bulimia Nervosa (BN) and co-occurring depression. While changes in symptoms of Eating disorder (ED) and depression have been found to correlate, it is unclear how they interact during treatment and in which order the symptoms decrease. METHODS Thirty-one patients with BN and depressive symptoms received IPT using the manual IPT-BNm in a naturalistic design. The outcome was measured with the Eating Disorder Examination Questionnaire (EDE-Q) and the Montgomery Åsberg Depression Rating Scale (MADRS-S). Symptom improvement at each session was measured with Repeated Evaluation of Eating Disorder Symptoms (REDS) and the Patient Health Questionnaire-9 (PHQ-9). RESULTS Significant improvements with large effect sizes were found on both ED symptoms and depression. The rates of change were linear for both BN and depression. A strong correlation between reduction of depressive symptoms and ED symptoms was found. Depressive symptom reduction at one session predicted improvement of ED symptoms at the next session. CONCLUSIONS IPT-BNm had an effect on both BN and co-occurring depressive symptoms. The analyses indicated that reduction in depressive symptoms preceded reduction in bulimic symptoms.

Abstract
OBJECTIVE We examined distinctiveness of different aspects of body-image disturbance in persons categorized with eating/weight disorders. We compared dissatisfaction with weight/shape, overvaluation of weight/shape, preoccupation with weight/shape, and fear of weight gain - in three study groups of persons categorized with overweight/obesity [O/O], bulimia nervosa [BN], and binge-eating disorder [BED] and examined how each body-image construct relates to clinical measures within and between the study groups. METHOD 1017 community volunteers completed measures of body-image, eating-disorder psychopathology, and depression. Participants were categorized into three study groups: O/O (N = 511), BN-purging type (N = 167), and BED (N = 339). RESULTS Groups differed significantly on the four body-image constructs (medium-to-large effect sizes) with a consistent severity gradient with BN greater than BED greater than O/O. Both within and between groups, the four body-image constructs varied in strengths of association among themselves and with clinical measures. Analyses revealed considerable variability in variance accounted for in the clinical measures; distinctive significant patterns observed across the groups included: dissatisfaction with BMI, preoccupation and fear with eating concerns and restraint, and overvaluation with depression. CONCLUSION Clinical manifestations of body-image disturbances are complex and show important differences across study groups defined as overweight/obesity, BN, and BED. Improved understanding of distinctions between different body-image constructs and their differential salience across different eating/weight disorders is needed to improve case conceptualization and treatment formulation.

Abstract
OBJECTIVE Frequent self-weighing is recommended in weight loss interventions and may prevent weight gain. However, concerns regarding the associations between self-weighing and eating disorders have been expressed and the relations between self-weighing and weight gain/eating pathology have not been examined prospectively. We tested whether (a) frequency of baseline self-weighing in college students with weight concerns predicted weight change over 2-year follow-up, (b) this relation was moderated by eating disorder symptoms, and (c) self-weighing predicted future eating disorder symptoms. METHOD Data were merged from two trials evaluating obesity/eating disorder prevention programs in 762 students (Mage = 18.7; 86% women). Participants reported how often they weighed themselves at baseline; body mass index (BMI) and eating disorder symptoms were assessed over 2-year follow-up. RESULTS Baseline self-weighing predicted weight gain, with more frequent weighers experiencing greater gains (i.e., +0.8 of BMI) over follow-up. This relation was moderated by the frequency of binge eating but not weight/shape concerns or compensatory behaviors; the combination of more frequent self-weighing and binge eating was associated with greatest weight gain (+1.6 of BMI). More frequent weighers also reported higher onset of compensatory behaviors, relative to non-self-weighers (odds ratio = 3.90, 95% confidence interval [1.76, 8.75]). CONCLUSIONS Young adults who weighed themselves more frequently had greater weight gain than those who self-weighed less frequently, especially those who engaged in binge eating, and were at risk for future unhealthy compensatory behaviors. Findings suggest that frequent self-weighing may have negative effects for some young adults, and that relations between self-weighing and weight control outcomes require further investigation.

Abstract
BACKGROUND AND OBJECTIVES Perfectionism is a transdiagnostic process that has been associated with a range of psychopathology and also with other transdiagnostic processes. We have previously shown that guided internet-based cognitive behavioural therapy (ICBT) can reduce symptoms of dysfunctional perfectionism, however, no impact was observed on symptoms of depression and anxiety. Here we explore the impact of guided ICBT for perfectionism on symptoms of other associated psychopathology, specifically obsessive-compulsive disorder (OCD) and eating disorders, and also on other associated transdiagnostic processes (self-esteem, intolerance of uncertainty, and self-compassion). METHODS Participants who presented with clinical levels of perfectionism were randomised to an experimental group that received the intervention (n = 62), or a wait list control group (n = 58). Questionnaires assessing symptoms of OCD, eating disorders, self-esteem, intolerance of uncertainty, and fear of self-compassion were completed pre-intervention, post-intervention (12 weeks), and at follow-up (24 weeks). Between group effect sizes are reported. RESULTS The intervention led to significant decreases in symptoms of OCD (d = -0.9; CI: -1.4, -0.4) and eating disorders (d = -0.6; CI: -1.0, -0.1), and had an impact on other transdiagnostic processes resulting in increased self-esteem (d = 0.7; CI: 0.2, 1.2), decreases in intolerance of uncertainty (d = -0.9; CI: -1.4, -0.4), and fear of self-compassion (d = -0.8; CI: -1.3, -0.3). At follow-up changes were maintained in symptoms of OCD (d = -1.3; CI: -1.8, -0.8), disordered eating (d = -0.7; CI: -1.2, -0.2), intolerance of uncertainty (d = -0.8; CI: -1.2, -0.3), and fear of self-compassion (d = -1.0; CI: -1.5, -0.5). CONCLUSIONS Guided ICBT for perfectionism improves associated psychopathology and transdiagnostic processes. ClinicalTrials.gov registration no. NCT02756871.
