Abstract
Binge eating (BE) is consuming large amounts of food in a short time, while experiencing loss of control over eating behavior. BE can be hereditary, and juvenile stress (JS) may contribute to its onset. We examined the impact of JS on BE-like behavior, in an animal model of intergenerational BE. Twenty-four female Wistar rats received 2-h access to palatable food (PF) three or five times a week (3 TW or 5 TW) for 4 weeks, followed by the open field test (OFT). At postnatal day (PND)27-29, female offspring either underwent JS (O-JSC) or not (O-CC). At PND51-53, offspring's stress levels were assessed behaviorally. At PND70-85, offspring received 2-h access to PF three times a week to assess their BE-like tendency. Hair samples were collected afterwards. Compared to 5 TW, 3 TW had a greater binge size. In the elevated plus maze and dark\light box, in O-JSC, offspring of 3 TW (O-3TW) spent less time in the open arms and lit area compared to O-5TW. O-3TW consumed more PF than O-5TW. O-JSC consumed more than O-CC. O-3TW-JSC had higher hair CORT levels than O-3TW-CC and O-5TW-JSC. This study highlights the interplay between maternal and offspring experiences, allowing for the study of underlying mechanisms.

Abstract
Background Eating disorders (ED) involve dysfunctional attitudes towards food intake, affecting physical and psychosocial well-being. These disorders significantly impact various domains of life and can lead to a decrease in health-related quality of life (HRQoL). Recent studies emphasize the importance of addressing HRQoL in ED treatment, particularly in the context of social isolation and loneliness, but this aspect is currently poorly evaluated. Methods A sample of 220 people with an ED was enrolled for the study from different centers specialized in the treatment of ED and compared to 151 people from the general population. Different validated questionnaires were used to evaluate eating psychopathology, HRQoL, and loneliness. Partial correlation analyzes adjusted for marital status and regressions were used to evaluate the relationships between constructs and the differences between groups. Results Higher feelings of loneliness were associated with a poorer HRQoL in patients and controls. In the ED group, both loneliness and eating psychopathology were significant predictors of HRQoL. Meanwhile, the duration of the disorder predicted HRQoL specifically in underweight patients, and BMI was a predictor of HRQoL in individuals with normal or above-normal weight. Conclusions These findings highlight the importance of considering both HRQoL and loneliness in EDs, particularly among younger individuals. This approach aligns with the increasing focus on the role of interpersonal relationships in the recovery process. Additionally, the data confirm a link between weight and loneliness, suggesting that this connection, especially the differences between underweight patients and those of other weights, deserves further investigation.

Self-reported food liking and wanting: A factor analytic study of ratings across 49 consecutive days. Appetite 2024; 201:107601.

Abstract
Reward responses to food are thought to play an important role in highly palatable food overconsumption. In animal models, food reward responses can be decoupled into unique "liking" (in the moment enjoyment) and "wanting" (motivation/craving) components. However, research on liking and wanting has been hampered by uncertainty regarding whether liking and wanting can be reliably separated in humans. We used factor analysis to test whether ratings of liking and wanting could be empirically separated in women assessed across 49 consecutive days. Female participants (N = 688; ages 15-30) from the Michigan State University Twin Registry reported liking and wanting of foods consumed that day, and wanting of foods not consumed that day, separately for sweets (e.g., cookies), fast food (e.g., French fries), carbohydrates (e.g., bread), and whole foods (fruit, plain chicken) each evening for 49 consecutive days. We examined both average levels and daily levels of liking/wanting across the 49-day period that captured individual differences in liking/wanting over time. Across both types of analyses, liking and wanting for foods that were eaten formed a single factor rather than separate, dissociable factors, while wanting of foods not eaten formed an independent factor. At the daily level, a liking/wanting factor emerged for each individual food category (e.g., liking/wanting sweets), whereas in average analyses, a single factor emerged that collapsed across all food types (i.e., liking/wanting of all foods). Results suggest individuals have difficulty distinguishing between liking and wanting of foods they have eaten on that day but may be able to more reliably separate wanting of foods they have not consumed.

Abstract
Attentional biases towards food play an important role in the pathology of binge eating disorder (BED). Later stage electrophysiological potentials (P300, late positive potential) present promising markers of motivated attention with high temporal, albeit low spatial resolution. Complementing this, the N2pc is an earlier-latency component providing the possibility of more directly analyzing visuospatial attention. Therefore, we tested a group with BED (N = 60), as well as an overweight (OW; N = 28) and normal weight (NW; N = 30) group without BED in a Go/No-Go paradigm using food and nonfood distractor images. Only the OW group in exclusively the Go trials displayed a stronger spatial attention allocation towards nonfood distractors as evidenced by an increased N2pc amplitude. In the P300's time window, the OW group displayed no attentional bias towards food and the NW group only did so in the absence of a target. Solely the BED group allocated more motivated attention towards food distractors both in Go and No-Go trials. In the following late positive potential (LPP), the OW group exhibited a general attentional bias towards food distractors, while the BED group only did so in the absence of a target. These results are discussed in light of the incentive sensitization theory and a potential early attentional suppression of potent distractors.

Abstract
Individuals with binge eating disorder (BED) exhibit a biased attention towards food stimuli. Against this backdrop, the present study with pre-registered design (ID: DRKS00012984) tested whether (a) a training designed to reduce attentional food processing indeed modifies this bias, (b) this reduction is evident in several measures of food-related attention and (c) this is associated with reductions in craving, binge frequency over the past 28 days and calories eaten in a laboratory based bogus taste test. Individuals with BED were randomly allocated to four sessions of either an attentional bias modification training (ABMT; n = 39) or a comparable no-modification control training (CT; n = 27). In all measures assessed via eye-tracking - dwell time bias, dwell time bias variability and first fixation bias - food-related bias decreased in the ABMT relative to the CT. Against our hypothesis, no differential between-group effects were found for reaction time (RT) bias and its variability as well as for calories consumed in a bogus taste test. By contrast, reductions in binge frequency and subjective craving were found for both groups. Taken together, the tendency to preferentially process food seems a modifiable phenomenon in individuals with BED. However, modifying this selective viewing pattern does not seem a prerequisite for a successful reduction of binge frequency.

Abstract
It is well-established that binge-eating (BE) is linked to emotion regulation (ER) difficulties. However, research to date has focused almost exclusively on difficulties regulating negative emotions, with little attention to the relationship between positive emotion dysregulation and BE. Further, research is inconclusive regarding which specific facets of ER difficulties are most strongly associated with BE behaviour. Therefore, the current study examined whether difficulties regulating both negative as well as positive emotions explained unique variance in BE among young adults. The study also aimed to identify which particular dimensions of negative and positive ER difficulties were most strongly related to BE symptoms. Participants (N = 449) ages 18-25 completed self-report measures of difficulties regulating positive and negative emotions, BE symptoms, and psychological distress. Hierarchical regression analyses showed that BE was related to difficulties regulating both positive emotions and negative emotions, after controlling for psychological distress and BMI. Lack of emotional clarity and lack of access to ER strategies when faced with strong negative emotions were the facets of negative ER difficulties most strongly associated with BE. Impulsivity when experiencing strong positive emotions was the facet of positive ER difficulties most strongly associated with BE. These findings support the ER model of BE and suggest that difficulties regulating both positive and negative emotions contribute to BE among young adults.

Abstract
Evidence-based treatments for binge eating disorder (BED), such as cognitive behavioral therapy (CBT) lead to successful outcomes only about half the time. Individuals with BED often have measurable deficits in executive function (EF) that may challenge adherence to or impact of cognitive behavioral intervention components. The aim of this study was to evaluate the impact of adding EF training to CBT by combining CBT with a compensatory cognitive training approach (EF-CBT). Participants were 32 adults with BED, overweight/obesity, and comorbid anxiety or depression who were randomly assigned to four months of group treatment in either standard CBT or EF-CBT. Outcomes were assessed at baseline, post-treatment, and at 2-month follow-up. Results showed that EF-CBT was feasible and acceptable, comparable to CBT. Both groups significantly decreased loss of control (LOC) days, clinical impairment, and depression at post-treatment and 2-month follow-up; though there were no differences between groups. Neither group significantly reduced anxiety or weight. Exploratory analyses found that participants with lower EF treated with EF-CBT were less likely to have LOC at post-treatment than those with lower EF treated with CBT. Higher self-monitoring rates during treatment were associated with lower LOC at post-treatment and participants with lower EF were more likely to self-monitor in the EF-CBT arm relative to the CBT arm. These findings suggest that EF-CBT is feasible, acceptable and efficacious, although larger scale research is needed. EF-CBT may be particularly suited for individuals with BED who have lower EF.

Abstract
Objectives: Researchers examined associations between specific forms of emotion dysregulation and numerous behavioral manifestations of impulsivity (i.e., problematic alcohol use, drug use, risky sexual activity, binge eating, non-suicidal self-injury). Participants: Participants were 238 undergraduate students (69% female). Method: Emotion dysregulation was assessed using the Difficulties in Emotion Regulation Scale (DERS). Path models examined each DERS subscale on its own, and all DERS subscales together, as predictors of all impulsive behaviors. Results: Lack of emotional clarity predicted the largest number of impulsive behaviors, both on its own and after controlling for other forms of emotion dysregulation. Non-acceptance of emotions and difficulties achieving goals when upset also related to several impulsive behaviors. Conclusions: Certain emotion regulation difficulties, particularly poor emotional clarity, may represent specific mechanisms that lead to maladaptive impulsive behaviors. Findings provide useful information for incorporating specific emotion regulation skills in harm prevention programs and treatments for university students.

Abstract
PURPOSE Binge eating is defined as consumption of a large amount of food accompanied by a sense of loss of control over eating. While binge eating is associated with poor physical, behavioral, and psychosocial health, it has not been studied in cancer research. Therefore, the overarching goal of this review is to delineate the role of binge eating in cancer research and to spur new research in this area. Specifically, in this review, we outlined (1) binge eating as a possible risk factor that contributes to cancer risk, (2) how binge eating may develop after cancer diagnosis, and (3) how binge eating may be associated with health and relapse during survivorship. CONCLUSIONS It is critical to elucidate the role of binge eating in the prevention of cancer and long-term cancer survivorship. This review suggested a number of ways that binge eating may increase risk for cancer as well as several pathways that may lead to the development of binge eating after cancer diagnosis.

Abstract
Objective Internet‐based guided self‐help (GSH) programs increase accessibility and utilization of evidence‐based treatments in binge‐eating disorder (BED). We evaluated acceptance and short as well as long‐term efficacy of our 8‐session internet‐based GSH program in a randomized clinical trial with an immediate treatment group, and two waitlist control groups, which differed with respect to whether patients received positive expectation induction during waiting or not. Method Sixty‐three patients (87% female, mean age 37.2 years) followed the eight‐session guided cognitive‐behavioural internet‐based program and three booster sessions in a randomized clinical trial design including an immediate treatment and two waitlist control conditions. Outcomes were treatment acceptance, number of weekly binge‐eating episodes, eating disorder pathology, depressiveness, and level of psychosocial functioning. Results Treatment satisfaction was high, even though 27% of all patients dropped out during the active treatment and 9.5% during the follow‐up period of 6 months. The treatment, in contrast to the waiting conditions, led to a significant reduction of weekly binge‐eating episodes from 3.4 to 1.7 with no apparent rebound effect during follow‐up. All other outcomes improved as well during active treatment. Email‐based positive expectation induction during waiting period prior to the treatment did not have an additional beneficial effect on the temporal course and thus treatment success, of binge episodes in this study. Conclusion This short internet‐based program was clearly accepted and highly effective regarding core features of BED. Dropout rates were higher in the active and lower in the follow‐up period. Positive expectations did not have an impact on treatment effects. The present internet‐based guided self‐help program adds to the existing research regarding online treatment of binge‐eating disorder and is currently one of the two existing validated programs available in German language. It is based on an established cognitive‐behavioural treatment approach, shows high acceptance by patients and high efficacy after eight guided online sessions, thereby representing the shortest duration of currently evaluated treatments During the internet‐based therapy, the number of weekly binge‐eating episodes, depressive symptoms, eating disorder pathology as well as impairments in psychosocial functioning all significantly decreased. These positive effects were maintained during follow‐up (6 months). Abstainer rate (no binge‐eating during last month) continued to increase during follow‐up with booster sessions An email‐based pre‐treatment positive expectation induction did not alter the temporal course and thus treatment success, of binge episodes

Abstract
Background: Binge eating disorder (BED) is clinically relevant by virtue of the global impairment, poor quality of life, and increased overall medical morbidity. The high comorbidity with psychiatric disorders, particularly depression, has received attention as a possible mediator of the poor outcome. Further, BED and depression share cognitive dysfunctions. This naturalistic and uncontrolled pilot study aimed at evaluating the efficacy of vortioxetine (VTX) on depressive symptoms in patients with BED, secondly the efficacy in improving a broad array of executive functions, and third to explore the effect on eating behavior and body weight. Methods: This pilot study involved 30 patients with BED and comorbid MDD, treated with VTX for 24 weeks. Assessments were run at baseline (t 0), 4 (t 1), 8 (t 2), 12 (t 3), and 24 (t 4) weeks. Changes in depressive symptoms (HDRS and BDI), executive functions, eating behaviors (binge frequency and severity, night eating, food addiction), and body weight were estimated after treatment with VTX through GLM. Results: Significant improvements emerged after treatment with VTX in: depression (HDRS p < 0.001; BDI p = 0.002) regardless the dose of VTX and first diagnosis (BED/MDD), working memory (RAVLT acquisition p = 0.01, delay recall p < 0.001, RCFT percentage of recall p = 0.01, and Attentional Matrices p = 0.05), binge days frequency (p < 0.001), binge eating severity (BES p < 0.001), night eating (p = 0.001), food addiction (YFAS 2.0 p = 0.039), and body weight (p = 0.039). The improvement in depressive symptoms was associated with the concurrent improvement in night eating as assessed by the I-NEQ. Conclusions: VTX can be a valid therapeutic choice for patients with BED with comorbid depression in controlling the depressive symptoms, working memory, and eating behavior. Indeed, by acting on affective symptoms, neurocognitive functioning, and eating behaviors, it confirms the results already obtained with VTX in other disorders, expanding them to BED.

Abstract
Introduction Binge behavior not only refers to the consumption of substances such as alcohol or food, but is also used in relation to gaming, watching and gambling. Dependent on context it makes for a widespread, benign recreational activity or can pose a serious mental health problem with deleterious consequences. Incentive sensitization theory describes the attribution of salience towards stimuli strongly associated with dopamine-mediated reward as a result of repeated consumption. The sensitized neural networks cause cue-triggered craving and excessive desire, but thus, this mechanism may also be applicable to stimulus-induced behaviors not associated with classical withdrawal symptoms. Event-related potentials (ERP) are a useful method of examining motivated attention towards incentive stimuli. This mini review aims to synthesize ERP findings from different types of binge behaviors in order to compare cue-reactivity to incentive stimuli. Methods Studies investigating binge drinking, binge eating as well as binge watching, gaming and gambling were screened. To limit the influence of concurrent task demands, ERP studies applying picture viewing paradigms with incentive stimuli were selected. Results Across binge behaviors, evidence on altered mid-latency ERPs has been mixed. However, studies investigating later stages of attentional processes more consistently find enlarged P300 and late positive potentials (LPP) amplitudes to relevant cues. Conclusion An altered attentional processing of incentive stimuli reflecting motivated attention is in line with incentive sensitization theory. Considering the limited number of studies, especially regarding binge behaviors not involving substances, more research is needed to attain a more thorough understanding of incentive sensitization across binge behaviors.

Abstract
OBJECTIVES To assess the implication of disordered eating behaviors (DEBs) on the quality of life (QOL) of a sample of the Lebanese population, after adjustment over sociodemographic characteristics of those participants. Secondary objective aimed to assess the role of body dissatisfaction (BD) in the association of DEBs and QOL. METHODS This cross-sectional study was done between January and May 2018 and enrolled 811 participants from the community. A proportionate random sample technique was used to select the sample from all Lebanese Mohafazat. The World Health Organization Quality-of-life (WHOQOL)-BREF was used to assess the QOL and it includes four domains: physical health, psychological health, social relations, and environment. RESULTS Body dissatisfaction was found to be a major confounding factor contributing to psychological and environmental HQOL impairments in patient with restrained eating. Nevertheless, orthorexia nervosa was associated with QOL impairments in its physical and environmental domains, regardless of body dissatisfaction that was shown to be a major contributor for QOL impairments. Similarly, ON was directly correlated with QOL of life impairment in its physical and environmental domains, independently of all other risk factors. CONCLUSION When adding body dissatisfaction as a confounding variable, restrained eating and orthorexia nervosa remained significantly associated with quality-of-life impairments. LEVEL OF EVIDENCE Level V, cross-sectional descriptive study.

Abstract
Loss of control eating is a core, transdiagnostic eating disorder symptom associated with psychological distress, functional impairment, and reduced quality of life. However, the factors that contribute to persistent loss of control eating despite negative consequences are not fully understood. Understanding the mechanisms that maintain loss of control eating is crucial to advance treatments that interrupt these processes. Affect regulation models of loss of control eating hypothesize that negative emotions trigger loss of control eating, and that loss of control eating is negatively reinforced because it temporarily decreases negative affect. Several variations on this basic affect regulation model have been proposed, including theories suggesting that negative affect decreases during loss of control eating rather than afterwards (escape theory), and that loss of control eating replaces one negative emotion with another that is less aversive (trade-off theory). Experience sampling designs that measure negative affect and eating behavior multiple times per day are optimally suited to examining the nuanced predictions of these affect regulation models in people's everyday lives. This paper critically reviews experience sampling studies examining associations between negative affect and loss of control eating, and discusses the implications for different affect regulation models of loss of control eating. The review concludes by proposing an expanded affect-focused model of loss of control eating that incorporates trait-level individual differences and momentary biological and environmental variables to guide future research. Clinical implications and recommendations are discussed.

Abstract
Depressive symptoms and binge eating are both prevalent in weight management populations and may be associated with reduced benefit from behavioral weight loss, including higher attrition, more perceived barriers, lower weight loss, and increased weight regain. These two potential risk factors for poor behavioral weight loss outcomes may also be associated with each other as depressive symptoms may trigger binge eating, and binge eating-related distress could increase depressive symptoms. The depressive symptom-binge eating link has not been well studied in weight management samples, and psychological processes involved in this relationship have not yet been elucidated. Psychological flexibility, an individual's ability to be connected with and conscious of the present moment and to engage in values-consistent behavior even in the presence of difficult internal experiences, may be one psychological process that changes the depressive symptom-binge eating relationship. High psychological flexibility may be a protective factor in the association of depressive symptoms with binge eating. This study examined the relationship between depressive symptom and binge eating and a potential interactive role of psychological flexibility. Participants (N = 468, 76% female) completed self-report questionnaires of binge eating, depressive symptoms, and psychological flexibility at baseline prior to initiating behavioral weight loss. Depressive symptoms were positively associated with binge eating (B = 1.00, p < 0.001). Psychological flexibility had an interactive role (B = -0.03, p = 0.005). Among participants with minimal to mild depressive symptoms, those with higher psychological flexibility had less severe binge eating. Findings suggest that psychological flexibility may be a protective factor in the association between depressive symptoms and binge eating in the majority of individuals initiating behavioral weight loss. Psychological flexibility is a psychological process to consider targeting for enhancing efficacy of weight loss treatment, especially among individuals with minimal to mild depressive symptoms and binge eating behavior.

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
Transtheoretical integrative decision-making models help clinicians to use patient factors that are known to predict outcomes in order to inform individualized treatment. Patient factors with a strong evidence base include: functional impairment, social support and interpersonal functioning, complexity and comorbidity, coping style, level of resistance, and level of subjective distress. Among those with binge-eating disorder (BED), patient factors have not been extensively characterized relative to norms or other clinical samples. We used an integrative decision-making model of these six patient factor domains related to patient outcomes to characterize a sample of 424 adults seeking treatment for BED. Data were from medical charts, a demographics questionnaire, and validated psychometric scales. We then compared these data to published data from normative and other eating disorder (ED) samples. Results showed that the average patient with BED: (1) was significantly more functionally impaired compared to non-clinical norms but somewhat less impaired than other patients with ED, (2) demonstrated clinically significant problems in social support and interpersonal functioning, (3) presented with complex comorbid pathology and high levels of chronicity, (4) used a more internalizing coping style compared to the norm and other ED samples, (5) had low levels of resistance to interventions, and (6) experienced a moderately high level of subjective distress indicating good motivation for treatment. Corresponding recommendations to these findings are that the average patient with BED should be provided higher intensity treatment that is longer in duration, interpersonally focused, directive in nature, and emphasizing self-reflection and insight. Despite the nomothetic nature of the findings, clinicians are encouraged to assess these patient domains when developing an ideographic case conceptualization and to tailor precision treatment to the individual patient with BED.

Abstract
OBJECTIVE The current study investigates the hypothesis that the effect of low self-esteem on binge eating in bariatric candidates was mediated by both difficulties in the perception of bodily signals and impulse regulation after accounting for gender, age, and body mass index. METHOD 59 preoperative patients (both male and female) were screened by means of self-report measures of self-esteem, interoceptive deficits, impulse dysregulation, and severity of binge eating. Results: Results indicated that all direct effects were significant, except for the self-esteem on impulse dysregulation and the interoceptive deficits on binge eating. Self-esteem had a significant indirect effect on impulse dysregulation mediated by interoceptive deficits. Impulse dysregulation, in turn, mediates the effect of interoceptive deficits on binge eating. Moreover, the path starting from self-esteem, going first to interoceptive deficits, then going via impulse regulation difficulties to binge eating was significant. RESULTS AND CONCLUSIONS A potential underlying mechanism through which self-esteem is linked to binge eating has been suggested. Obese individuals who perceived themselves as inadequate may carry a stronger burden by the confusion and mistrust related to bodily functioning and, consequently, may act more impulsively, through binge eating.

Abstract
OBJECTIVE This study examined what adults with binge-eating disorder (BED) and obesity perceived as the threshold for a large amount of food and how their evaluations compared to ratings by participants with obesity but without BED. METHOD This was a cross-sectional study of 150 participants with obesity. BED was assessed using the Questionnaire on Eating and Weight Patterns and confirmed via interview. Participants completed the Eating Patterns Questionnaire and Eating Inventory. RESULTS Participants with BED had significantly higher thresholds for a large amount of food relative to those without BED. Compared to participants without BED, those with BED had significantly higher thresholds on 13 of the 22 food items. In the overall sample, being male and having higher hunger scores were associated with greater thresholds. DISCUSSION Individuals with obesity and BED had larger portion standards than participants without BED. Individuals with BED may benefit from interventions targeted toward decreasing perceptions of portion sizes.

Abstract
Binge eating disorder (BED) is the most common eating disorder and is accompanied by multiple medical comorbidities, many of which are associated with obesity-related diseases. However, the BED itself is likely to confer additional risk factors. BED presents with medical symptoms in virtually every body system and can have devastating consequences on both quality and length of life. This review covers the major comorbidities of BED and highlights areas of ongoing research in this disorder.

Abstract
Research has found that individuals with binge eating disorder (BED) report significantly worse health-related quality of life (HRQL) than those without eating disorders. Studies indicate that the association between BED and HRQL is largely accounted for by psychopathology (e.g., depression), rather than physiology [e.g., increased body mass index (BMI)]. However, to our knowledge, no study has yet investigated whether mental health symptoms could potentially mediate the relationship between BED and HRQL. To this aim, the present study compared a sample of adults who met DSM-5 criteria for BED (n = 72) recruited from the community for a treatment trial and a community sample of individuals with no history of an eating disorder (NED; n = 79). Participants completed self-report measures of HRQL (Short-Form 6D), eating disorder psychopathology (Eating Disorder Examination Questionnaire), and anxiety and depressive symptoms (Brief Symptom Inventory). Consistent with previous findings, the BED group reported significantly worse HRQL than the NED group after controlling for age, BMI, anxiety, depression, and eating disorder psychopathology. Moreover, depression partially mediated the relationship between BED diagnosis and HRQL. These results suggest that lessened HRQL may be partly explained by comorbid symptoms of depression in BED. Clinicians may find it helpful to specifically assess and treat depression in BED as a means of enhancing patients' well-being. Future research should replicate these findings using longitudinal data that will allow for causal inferences.

Abstract
Binge eating disorder (BED) is characterized by periods of excessive food intake combined with subjective feelings of loss of control. We examined whether sucrose bingeing itself leads to uncontrolled or compulsive responding and whether this effect is magnified following a period of abstinence. We then assessed dopamine (DA) modulation of inhibitory synaptic transmission in the oval bed nucleus of the stria terminalis (ovBNST) as a neural correlate of compulsive responding and whether this behavioral effect could be disrupted by DA blockade in the ovBNST. Over 28 days, male Long-Evans rats (n = 8-16 per group) had access to 10% sucrose and food (12 or 24 h), 0.1% saccharin and food (12 h), or food alone (12 h). Compulsive responding was assessed following 1 or 28 days of sucrose abstinence using a conditioned suppression paradigm. Only rats given 12 h access to sucrose developed binge-like intake, manifested as copious intake within the first hour; compulsive responding was significantly elevated in this group following 28 days of abstinence. In parallel, the effect of DA on ovBNST inhibitory transmission switched from a reduction to a potentiation; the effect, although observable after 1 day, was more pronounced and sustained following 28 days of abstinence. Intra-ovBNST infusions of a DA D1 receptor antagonist (0.8 µg/µl SCH-23390) reversed the blockade of conditioned suppression, thereby confirming the causal relationship between ovBNST DA modulation of γ-aminobutyric acid transmission and alterations in conditioned suppression following binge-like intake of sucrose.

Abstract
Objective Differential participation in physical activity (PA) may partially explain the health discrepancies between individuals with or without binge-eating disorder (BED). Yet, little is known about the PA habits of individuals with overweight/obesity and how those patterns may differ based on BED status. PA patterns and exercise self-efficacy were examined in individuals with overweight/obesity, with and without BED. Design Ninety-seven participants with overweight/obesity self-reported their PA via the Godin Leisure-Time Questionnaire and the Paffenbarger PA Questionnaire. Exercise self-efficacy was assessed with the Marcus 5-item Exercise Self-Efficacy scale. Based on the Eating Disorder Examination, 27.8% (n = 27) of the participants met BED criteria. Participants were primarily female (n = 75, 77.3%), on average 47.5 years old (standard deviation = 10.4), and predominantly White/Not Hispanic (n = 67, 69.1%) or African-American/Not Hispanic (n = 18, 18.6%). Results Hierarchical regressions, accounting for significant differences in body mass index between those with and without BED, showed that the Marcus 5-item Exercise Self-Efficacy Scale (but not BED status) was significantly related to PA. BED status also was unrelated to likelihood of reaching Centres for Disease Control PA guidelines, and 44.3% of all participants reported no participation in weekly sports/recreation activities. Conclusions Both groups participated in relatively little purposeful and moderate/strenuous PA. Exercise self-efficacy may be important to assess and address among treatment seeking individuals with and without BED who struggle with excess weight.

Abstract
The Risk factors for Binge Eating Disorder in Overweight (REO) questionnaire is a screening tool for nutritionists to discriminate between individuals with obesity with and without Binge Eating Disorder (BED). The first study tested the discriminative ability of the REO and identified an optimal cut-off value. In the second study this cut-off value was used to identify individuals with and without BED from a sample of individuals with obesity visiting a nutritionist and compared clinical and personality characteristics with a group of individuals officially diagnosed with BED. Results showed that the REO has a sensitivity of 95.1%, specificity of 81.5%, a good internal consistency of α=.96, and an exploratory factor analysis showed four underlying factors of the REO that explained a total variance of 63.7%. Characteristics of individuals with BED symptoms identified by the REO and those officially diagnosed with BED were comparable and differed from individuals with obesity without BED symptoms. By screening individuals with obesity with the REO those presenting with BED symptoms are more easily identified, and can be referred to psychological treatment facilities for further assessment and appropriate treatment.

Abstract
OBJECTIVE This study aimed to investigate the relative contributions of binge eating, body image disturbance, and body mass index (BMI) to distress and disability in binge-eating disorder (BED). METHOD A community sample of 174 women with BED-type symptomatology provided demographic, weight, and height information, and completed measures of overvaluation of weight/shape and binge eating, general psychological distress and impairment in role functioning. Correlation and regression analyses examined the associations between predictors (binge eating, overvaluation, BMI), and outcomes (distress, functional impairment). RESULTS Binge eating and overvaluation were moderately to strongly correlated with distress and functional impairment, whereas BMI was not correlated with distress and only weakly correlated with functional impairment. Regression analysis indicated that both overvaluation and binge eating were strong and unique predictors of both distress and impairment, the contribution of overvaluation to variance in functional impairment being particularly strong, whereas BMI did not uniquely predict functional impairment or distress. DISCUSSION The findings support the inclusion of overvaluation as a diagnostic criterion or specifier in BED and the need to focus on body image disturbance in treatment and public health efforts in order to reduce the individual and community health burden of this condition.

Abstract
Individuals with obesity and binge eating disorder (BED) report poorer weight-related quality of life (WRQOL) compared to individuals with obesity alone. Cognitive behavioral therapy (CBT), the best available treatment for BED, does not consistently produce weight loss or improvements in weight QOL. The purpose of the current study was to examine baseline and longitudinal associations between eating-related and psychosocial variables and dimensions of weight QOL. We examined associations between predictor variables, including body mass index (BMI), eating disorder (ED) psychopathology, and psychosocial factors, in relation to three dimensions of WRQOL among 171 patients whom received CBT for BED. Participants completed interviews and self-report measures at baseline prior to CBT and at end of treatment. At baseline the following associations were significant: BMI, ED psychopathology, and self-esteem were associated with weight-related self-esteem; gender, BMI, and self-esteem were associated with weight-related public distress (i.e., stigma and worry in public because of one's weight); and age, BMI, and ED psychopathology were associated with weight-related physical function. At end of treatment, the following associations were significant: changes in ED psychopathology and coping predicted weight-related self-esteem; changes in coping and self-esteem predicted weight-related public distress; and changes in BMI and subjective binge eating predicted weight-related physical function. Overall, changes in a number of ED and associated symptoms were associated with improvements in WRQOL.

Abstract
OBJECTIVE The emotion regulation (ER) model of binge eating posits that individuals with binge-eating disorder (BED) experience more intense emotions and greater difficulties in ER than individuals without BED, leading them to binge eat as a means of regulating emotions. According to this model, individuals with BED should report greater difficulties in ER than their non-BED counterparts, the severity of these difficulties should be positively associated with BED symptoms, and this association should be stronger when individuals experience persistent negative emotions (i.e., depression). Studies examining these hypotheses, however, have been limited. METHOD Data were collected from adults meeting the DSM 5 criteria for BED (n = 71; 93% female) and no history of an eating disorder (NED; n = 79; 83.5% female). Participants completed self-report measures of difficulties in ER, eating disorder (ED) psychopathology, and depression. RESULTS Individuals with BED reported greater difficulties in ER compared to those with NED. Moreover, difficulties in ER predicted unique variance in binge frequency and ED psychopathology in BED. Depression moderated the association between ER difficulties and binge frequency such that emotion dysregulation and binge frequency were positively associated in those reporting high, but not low, depression levels. DISCUSSION The association between difficulties in ER and ED pathology in BED suggests that treatments focusing on improving ER skills may be effective in treating this ED; however, the moderating effect of depression underscores the need for research on individual differences and treatment moderators. These findings suggest the importance of ER in understanding and treating BED.

Abstract
OBJECTIVES To investigate whether training individuals from the personal networks of adults with obesity in the skills of motivational interviewing enhances the anthropometric and psychological outcomes of a cognitive-behavioural weight loss intervention. METHODS Adults with obesity (N = 201) were randomised to participate in 26 sessions of cognitive behaviour therapy (CBT) for weight loss either alone (CBT-A) or with the addition of a support person (CBT-SP). Outcomes were assessed at the end of the 12-month intervention and at a follow-up one year later. RESULTS Analyses indicated negligible additive effect for the CBT-SP versus the CBT-A condition, although the quality of the patient's relationship with their support person predicted the anthropometric outcomes. Across conditions, significant improvements were observed for all anthropometric (weight, body mass index, and waist circumference) and psychological (self efficacy, weight-related quality of life, weight satisfaction, and binge eating) variables between baseline and post-treatment, and baseline and the follow-up. CONCLUSIONS The benefits of the cognitive-behavioural weight loss program were found to extend to psychological variables. Yet the lack of evidence for the additive benefits of including support people in treatment suggests a need to develop more effective training programs for support people in weight management.

Abstract
Recurrent binge eating, or overeating accompanied by a sense of loss of control, is a major public health concern. Identifying similarities and differences among individuals with binge eating and those with other psychiatric symptoms and characterizing the deficits that uniquely predispose individuals to eating problems are essential to improving treatment. Research suggests that altered reward and control-related processes may contribute to dysregulated eating and other impulsive behaviors in binge-eating populations, but the best methods for reliably assessing the contributions of these processes to binge eating are unclear. In this review, we summarize standard neurocognitive and neuroimaging tasks that assess reward and control-related processes, describe adaptations of these tasks used to study eating and food-specific responsivity and deficits, and consider the advantages and limitations of these tasks. Future studies integrating both general and food-specific tasks with neuroimaging will improve understanding of the neurocognitive processes and neural circuits that contribute to binge eating and could inform novel interventions that more directly target or prevent this transdiagnostic behavior.

Abstract
INTRODUCTION Food addiction is a controversial concept. The potential influence of food addiction on patients' psychosocial functioning and well-being has not been well established. The purpose of this study was to examine the relationships between psychosocial functioning (depressive symptoms and health-related quality of life [HRQOL]) and food addiction as measured by the Yale Food Addiction Scale (YFAS). We also explored whether food addiction contributed additional variance in explaining psychosocial functioning, beyond demographic and clinical factors (e.g., binge eating). METHODS The sample included 178 participants (mean age=44.2±11.2years; BMI=40.9±5.9kg/m2; 88.2% female; 70.8% Black) with obesity seeking treatment for weight loss. Participants completed the Medical Outcomes Study 36-Item Short-Form Health Survey, Impact of Weight on Quality of Life-Lite, Patient Health Questionnaire, YFAS, and Questionnaire on Eating and Weight Patterns-5. RESULTS Twelve (6.7%) participants met criteria for food addiction, with 4 (33.3%) of these participants having co-occurring binge eating disorder. After adjusting for covariates, the number of food addiction symptoms accounted for 6.5% to 16.3% of additional variance in general HRQOL, 5.0% to 21.5% in weight-related HRQOL, and 19.1% in symptoms of depression. CONCLUSIONS In this treatment-seeking sample of participants, we found a low prevalence of food addiction, suggesting that addictive-like eating is unlikely to be a causal mechanism for most people with obesity. However, individuals who met criteria for food addiction had reduced psychosocial functioning compared to those who did not meet criteria. Individuals with addictive-like eating may require additional psychosocial support.

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

Abstract
BACKGROUND Although not part of the diagnostic criteria of the DSM-5, body image disturbance seems to be a relevant feature of Binge Eating Disorder (BED) as well as of other eating disorders such as Anorexia Nervosa (AN) or Bulimia Nervosa (BN). Hence, the aim of the present pilot study was to assess the changeability of body image disturbance in a sample of overweight females with BED by a cognitive-behavioral treatment, directly addressing body image disturbance. METHOD Overweight females (N = 34) with BED were randomized to a manualized body image therapy or a waiting-list control group. The final sample consisted of n = 15 participants in the intervention group and n = 19 in the control group due to two drop-outs in the control condition. Before and after the intervention or the waiting period, respectively, participants filled out a questionnaire battery assessing several body image and eating disorder related features. To quantify the perceptual component of body image disturbance, a digital photo distortion technique based on a picture of each participant taken in a standardized suit was applied. RESULTS In a two-way ANOVA, significant Time × Group interactions were found for eating and shape concerns, drive for thinness, body dissatisfaction, depressiveness and low self-esteem. Follow-up t-tests indicated a significant symptom reduction of a generally high magnitude in the intervention group. No significant changes concerning body checking and the estimations of one's own "real", "felt" and "ideal" body dimensions were found. CONCLUSION The strong symptom reduction in the cognitive-affective component of body image disturbance indicates that an exposure-based cognitive-behavioral body image intervention is a promising treatment module for overweight females with BED, but future research with a larger sample size is needed to quantify possible changes in all components of body image.

Abstract
The purpose of the current study was to investigate stress-induced eating in women with binge-eating disorder (BED) and obesity. Three groups of women [obese with BED (n=9); obese non-BED (n=11); and normal weight (NW) non-BED (n=12)], rated their levels of hunger and psychological distress before and after completing the Trier Social Stress Test, followed by food anticipation and then consumption of their preferred snack food. We differentiated between the motivational and hedonic components of eating by measuring the amount of food participants poured into a serving bowl compared to the amount consumed. Stress did not affect poured and consumed calories differently between groups. Across all subjects, calories poured and consumed were positively correlated with post-stress hunger, but calories poured was positively correlated with post-stress anxiety and negative affect. These results indicate that stress-related psychological factors may be more strongly associated with the motivational drive to eat (i.e. amount poured) rather than the hedonic aspects of eating (i.e. amount consumed) for women in general. Exploratory correlation analyses per subgroup suggest that post-stress hunger was positively associated with calories poured and consumed in both non-BED groups. In the obese BED group, calories consumed was negatively associated with dietary restraint and, although not significantly, positively associated with stress-induced changes in anxiety.These findings suggest that stress-induced snacking in obese BED women may be influenced by psychological factors more so than homeostatic hunger mechanisms. After controlling for dietary restraint and negative affect, the NW non-BED women ate a greater percentage of the food they poured than both obese groups, suggesting that obesity may be associated with a heightened motivational drive to eat coupled with a reduction in hedonic pleasure from eating post-stress. Further studies that incorporate novel approaches to measuring the motivational versus hedonic aspects of stress-induced eating may expose nuanced eating behaviors that differentiate BED and obesity. If confirmed, our findings would support prevention and treatment strategies that target subsets of women based on obesity and BED status.

Abstract
BACKGROUND AND OBJECTIVES Binge eating is prevalent and is associated with significant psychiatric and medical comorbidities. To date, the most effective psychological treatments for individuals who binge eat are not effective for all patients and they do not result in significant weight loss. Dual process theories suggest that implicit factors, such as attention bias, may influence behavior, even when the behavior is in opposition to long-term goals. Attention bias modification programs have been tested in other areas of psychopathology, and could be utilized to improve outcomes for people who binge eat. Thus, the aim of this open trial was to conduct a preliminary evaluation of an attention bias modification program (ABM-Food) designed to train attention away from food cues. METHODS Adults who binge eat and were overweight or obese enrolled in an 8-week ABM-Food program, which consisted of one session in the lab each week and two training sessions at home. Nine participants completed the ABM-Food training program and the post-treatment assessment, and 8 completed the 3-month post-treatment assessment. RESULTS Results showed that the ABM-Food program is a feasible and acceptable treatment for adults who binge eat. Initial effectiveness data showed decreases in weight, eating disorder symptoms, binge eating, loss of control and responsivity to food in the environment, as well as changes in attention bias. The majority of these effects remained at the 3-month follow-up time point. LIMITATIONS This study is limited by the single-group open label trial, and the small sample size. CONCLUSIONS This open trial provides initial evidence for the feasibility, acceptability and effectiveness of ABM-Food for individuals who binge eat and are overweight or obese.

Abstract
PURPOSE To perform a systematic review of the health-related quality of life (HRQoL) and economic burdens of anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). METHODS A systematic literature search of English-language studies was performed in Medline, Embase, PsycINFO, PsycARTICLES, Academic Search Complete, CINAHL Plus, Business Source Premier, and Cochrane Library. Cost data were converted to 2014 Euro. RESULTS Sixty-nine studies were included. Data on HRQoL were reported in 41 studies (18 for AN, 17 for BN, and 18 for BED), on healthcare utilization in 20 studies (14 for AN, 12 for BN, and 8 for BED), and on healthcare costs in 17 studies (9 for AN, 11 for BN, and only 2 for BED). Patients' HRQoL was significantly worse with AN, BN, and BED compared with healthy populations. AN, BN, and BED were associated with a high rate of hospitalization, outpatient care, and emergency department visits. However, patients rarely received specific treatment for their eating disorder. The annual healthcare costs for AN, BN, and BED were €2993 to €55,270, €888 to €18,823, and €1762 to €2902, respectively. CONCLUSIONS AN, BN, and BED have a serious impact on patient's HRQoL and are also associated with increased healthcare utilization and healthcare costs. The burden of BED should be examined separately from that of BN. The limited evidence suggests that further research is warranted to better understand the differences in long-term HRQoL and economic burdens of AN, BN, and BED.

Abstract
Internalized weight bias has been previously associated with impairments in eating behaviors, body image, and psychological functioning. The present study explored the psychological correlates and psychometric properties of the Weight Bias Internalization Scale (WBIS) among overweight adults enrolled in a behavioral weight loss program. Questionnaires assessing internalized weight bias, anti-fat attitudes, self-esteem, body image concern, and mood symptoms were administered to 90 obese or overweight men and women between the ages of 21 and 73. Reliability statistics suggested revisions to the WBIS. The resulting 9-item scale was shown to be positively associated with body image concern, depressive symptoms, and stress, and negatively associated with self-esteem. Multiple linear regression models demonstrated that WBIS scores were significant and independent predictors of body image concern, self-esteem, and depressive symptoms. These results support the use of the revised 9-item WBIS in treatment-seeking samples as a reliable and valid measure of internalized weight bias.

Abstract
Binge eating disorder (BED), now recognized as a distinct eating disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, is the most prevalent eating disorder. Although nearly half of individuals with BED are obese, BED also occurs in nonobese individuals. Despite the relatively high percentage of weight loss treatment-seeking individuals meeting BED criteria, primary care physicians may not be familiar with or have ever diagnosed BED. Many providers may also have difficulty distinguishing BED as a contributory factor in obesity. This review differentiates BED from other causes of obesity by describing how obese individuals with BED differ from obese individuals without BED and from nonobese individuals with BED in areas including psychopathology, behavior, genetics, physiology, quality of life and productivity. The ways in which health-care providers can identify individuals who may have BED are also highlighted so the proper course of treatment is pursued. Overall, obese individuals with BED demonstrate a number of key characteristics that differentiate them from obese individuals without eating disorders, including increased impulsivity in response to food stimuli with loss of control over eating, resulting in the consumption of more calories. They also experience significant guilt and other negative emotions following a meal. In addition, individuals with BED patients have more psychiatric comorbidity, display more psychopathology, exhibit longer binge durations, consume more meals as snacks during the day and have less dietary restraint compared with individuals with BED who are not obese. However, the differences between individuals with BED who are obese versus not obese are not as prominent. Taken together, the evidence appears to support the conclusion that BED is a unique and treatable neurobehavioral disorder associated with distinct behavioral and psychological profiles and distinct medical and functional outcomes, and that it is not merely a subtype of obesity.

Abstract
BACKGROUND Acupuncture is considered to be an effective and safe treatment for obese and overweight patients, although high-quality evidence regarding the effects of acupuncture on obesity are not conclusive. The aim of the current study is to investigate the effectiveness of electro-acupuncture plus lifestyle modification for treating obese and overweight patients, in comparison with lifestyle modification alone in China. METHODS/DESIGN To compare the effectiveness of acupuncture plus lifestyle modification, a 2-armed, controlled trial with randomization using minimization will be conducted on 150 simple obesity and overweight patients, aged 18-50 years, for a 36-week study duration. All patients will be randomly assigned to one of two groups and will receive either acupuncture plus lifestyle modification or lifestyle modification alone. Outcomes will be evaluated at baseline and at 4 weeks, 8 weeks, and 12 weeks during treatment as well as at 6-week, 12-week, and 24-week follow-up. The primary endpoint is change of body mass index (BMI) during the 12th week. Secondary endpoints are body weight; waist-to-hip ratio; biochemical tests including serum cholesterol (TC), triglyceride (TG) and high-density lipoprotein (HDL) levels; and answers to the Short Form 36 (SF-36) and the Impact of Weight on Quality of Life Questionnaire-Lite Version (IWQOL-Lite). Statistical analyses will be based on the intention-to-treat (ITT) principle. The main endpoint will be analyzed by analysis of covariance (ANCOVA), and the objective outcome results will be analyzed by logistic regression analysis. To avoid potential confounding factors, additional sensitivity analyses will be conducted following these statistical analyses. DISCUSSION This trial is the first to compare the effectiveness of acupuncture plus lifestyle modification for treating obesity relative to lifestyle modification treatment alone by using a pragmatic study design. We hope that the results of this study will contribute to advancing the current methodology of acupuncture trials for obesity and will facilitate the application of useful acupuncture strategies in real-world clinical settings.

Abstract
OBJECTIVE To examine metabolic factors among overweight/obese individuals with binge-eating disorder (BED) and non-binge-eating overweight/obese (NBO) patients recruited from primary care and to examine and compare medication use by these groups. METHOD Participants were 102 adults recruited for a weight loss study within primary care centers who were assessed for BED (28 [38%] met DSM-5 BED criteria). Participants completed a medication log, had physiologic measurements taken, and were evaluated for the presence of metabolic syndrome using 2 methods. Data were collected between February 2012 and October 2012. RESULTS The BED group had a higher mean body mass index (BMI), a higher pulse, and a larger waist circumference than the NBO group. Of the sample, 65% reported current medication use (prescription and/or over-the-counter medications): 19.6% took 3 to 4 medications and 15.7% took ≥ 5 medications. Aside from vitamin and over-the-counter allergy pill use, there were no differences in medication use between BED and NBO patients. Full metabolic syndrome (≥ 3 criteria met) was present in 31.5% of the sample when using objective measurement alone, and 39.1% of the sample when defined by objective measurement and pharmacologic management. No significant differences were observed regardless of definition. CONCLUSIONS Despite higher BMI, pulse, and waist circumference, the current sample of BED patients in primary care did not present with poorer metabolic health than NBO patients.

Abstract
Background Health-related quality of life (HR-QoL) may be compromised in obese individuals, depending on the presence of other complications. The aim of this study is to assess the effect of obesity-related conditions on HR-QoL. These conditions are i) grade of obesity with and without type 2 diabetes (T2D), ii) metabolic syndrome (MetS), and iii) level of inflammation. Methods From the Dutch LifeLines Cohort Study we included 13,686 obese individuals, aged 18–80 years. HR-QoL was measured with the RAND 36-Item Health Survey which encompasses eight health domains. We calculated the percentage of obese individuals with poor HR-QoL, i.e. those scoring below the domain and sex specific cut-off value derived from the normal weight population. Logistic regression analysis was used to calculate the probability of having poor domain scores according to the conditions under study. Results Higher grades of obesity and the additional presence of T2D were associated with lower HR-QoL, particularly in the domains physical functioning (men: odds ratios (ORs) 1.48–11.34, P<0.005, and women: ORs 1.66–5.05, P<0.001) and general health (men: ORs 1.44–3.07, P<0.005, and women: ORs 1.36–3.73, P<0.001). A higher percentage of obese individuals with MetS had a poor HR-QoL than those without MetS. Furthermore, we observed a linear trend between inflammation and the percentage of obese individuals with poor scores on the HR-QoL domains. Individuals with MetS were more likely to have poor scores in the domains general health, vitality, social functioning and role limitations due to emotional problems. Obese women with increased inflammation levels were more likely to have poor scores on all domains except role limitations due to emotional problems and mental health. Conclusions The impact of obesity on an individual’s quality of life is enhanced by grade of obesity, T2D, MetS and inflammation and are mainly related to reduced physical health. The mental well-being is less often impaired.

Abstract
OBJECTIVE The purpose of the present study was to examine the cognitive, emotional and behavioral differences between obese and normal weight women. METHODS The participants consisted of 60 obese women (BMI ≥ 35, Mean age 35.83) who were candidates for bariatric surgery and 60 normal weight women (BMI ≤ 24.90, Mean age 33.38) who were selected through convenient sampling method. The two groups were matched with respect to age and education. Measures included the Young Schema Questionnaire-Short Form, Difficulties in Emotion Regulation Scale (DERS) and the Binge Eating Scale. Independent sample t test and Mann-Whitney U tests were conducted to compare the two groups' scores on early maladaptive schemas, DER and binge eating. RESULTS Results indicated that obese women candidate for bariatric surgery scored significantly higher on emotional deprivation, mistrust, failure, dependency, enmeshment, self-sacrifice, especially abandonment, social isolation, vulnerability, self-control and subjugation schemas, but not on shame, entitlement, emotional inhibition and unrelenting standards. Obese women also displayed higher scores on three subscales of DERS, i.e., goal, impulse and strategies. BE scores were significantly higher in obese women than normal weight ones. CONCLUSION The findings showed that obese women candidates for bariatric surgery suffered from more cognitive, emotional and behavioral vulnerability compared to women with normal weight. Addressing these vulnerabilities among obese women could improve outcomes of weight loss surgeries and cognitive behavioral interventions so that weight regain is minimized and better outcomes are achieved.

Perceptions of the feasibility and acceptability of a smartphone application for the treatment of binge eating disorders: Qualitative feedback from a user population and clinicians. Int J Med Inform 2015; 84:808-16.

Abstract
BACKGROUND Binge eating, a major public health problem, is characterized by recurrent episodes of out-of-control eating in which an individual consumes an unusually large amount of food in a discrete time period. Limitations of existing treatments for binge eating (both in-person psychotherapy and guided self-help) indicate that smartphone applications (apps) may be an ideal alternative or enhancement. An app for binge eating could aid treatment dissemination, engagement, and/or compliance. However, no research to date has examined user perceptions of a therapeutic app for binge eating, which is critical for development. OBJECTIVES The purposes of the current study were to conceptualize a potential app for binge eating and obtain feedback regarding feasibility and acceptability from target users (i.e., individuals with binge eating) and clinicians specializing in the treatment of binge eating. METHODS Our team conceptualized a smartphone app that contained self-help material, functions to monitor behavior, and provisions of in-the-moment interventions. We presented this app (e.g., feature explanations, mock screen shots) through phone interviews with clinicians who specialize in the treatment of binge eating (n=10), and focus groups with individuals experiencing binge eating (n=11). Participants were asked to discuss customization, user burden, terminology, attrition, data visualization, comprehensiveness, reminders, feasibility, acceptability, and perceived effectiveness of the proposed app. Thematic analyses were conducted from qualitative data (e.g., audio recordings and interview notes) obtained via the focus groups and interviews. RESULTS Results indicated that our proposed app would be highly feasible and acceptable to users and clinicians, though concerns about the degree of personalization and customizability were noted. CONCLUSIONS The current study details highly specific feedback and ideas regarding essential app features from target users and clinicians. This information is critical for the development of future apps to treat binge eating. Ways in which data obtained from the current study may be generalized to the development of therapeutic apps for other psychological disorders is discussed.

Abstract
OBJECTIVE Although binge eating disorder (BED) is the most prevalent eating disorder, the impact of untreated BED is underappreciated. This review describes the relationship of BED to physical and mental health, quality of life, and functionality. DATA SOURCES PubMed searches were conducted on March 21, 2014; searches were limited to English-language research articles, meta-analyses, and reviews published between January 1, 2003 and March 21, 2014. Search terms included (binge eating OR binge-eating OR binge eating disorder) AND (cardiovascular OR metabolic OR metabolic syndrome OR gastrointestinal OR health OR rehabilitation OR recovery OR sleep OR pregnancy OR quality of life OR functional impairment OR activities of daily living OR QoL OR SF-12 OR ED-5D OR SF-36 OR psychosocial OR depressive OR anxiety OR self-esteem OR suicidality OR suicide OR productivity OR family). STUDY SELECTION/DATA EXTRACTION Of 326 identified publications, 43 were relevant to the topic and reported on the association of BED with psychiatric and medical comorbidities, quality of life, and functional outcomes. RESULTS Individuals diagnosed with BED have increased rates of mental health comorbidities (eg, depression and anxiety) and more pronounced medical impairments (eg, cardiovascular disorders) compared with individuals without BED. BED is also associated with functional impairment and reduced quality of life. CONCLUSIONS Binge eating disorder is associated with impairments in physical and mental health, which can decrease quality of life and functionality and lead to increased health care utilization and decreased productivity. However, some caution is warranted in interpreting these findings because it remains unclear whether BED is an antecedent condition, a complication associated with a comorbid psychiatric condition, or an unrelated feature that occurs concurrently with these comorbidities and impairments. Much of the research on BED is based on observational or epidemiologic studies. Controlled studies are needed to clearly define the long-term impairments associated with BED.
