Abstract
Mindfulness meditation may improve well-being at work; however, effects on food cravings and metabolic health are not well known. We tested effects of digital meditation, alone or in combination with a healthy eating program, on perceived stress, cravings, and adiposity. We randomized 161 participants with overweight and moderate stress to digital meditation ('MED,' n = 38), digital meditation + healthy eating ('MED+HE,' n = 40), active control ('HE,' n = 41), or waitlist control ('WL,' n = 42) for 8 weeks. Participants (n = 145; M(SD) BMI: 30.8 (5.4) kg/m2) completed baseline and 8-week measures of stress (Perceived Stress Scale), cravings (Food Acceptance and Awareness Questionnaire) and adiposity (sagittal diameter and BMI). ANCOVAs revealed that those randomized to MED or MED+HE (vs. HE or WL) showed decreases in perceived stress (F = 15.19, p < .001, η2 = .10) and sagittal diameter (F = 4.59, p = .03, η2 = .04), with no differences in cravings or BMI. Those high in binge eating who received MED or MED+HE showed decreases in sagittal diameter (p = .03). Those with greater adherence to MED or MED+HE had greater reductions in stress, cravings, and adiposity (ps < .05). A brief digital mindfulness-based program is a low-cost method for reducing perceptions of stress and improving abdominal fat distribution patterns among adults with overweight and moderate stress. Future work should seek to clarify mechanisms by which such interventions contribute to improvements in health.

Abstract
We examined change in defensive functioning following group psychodynamic-interpersonal psychotherapy (GPIP) for binge-eating disorder (BED) compared to a waitlist control. We hypothesized that defensive functioning will improve to a greater extent at posttreatment for those in GPIP compared with those in a waitlist control condition. Participants were women with BED assigned to GPIP (n = 131) or a waitlist control (n = 44) condition in a quasi-experimental design. Those who received GPIP had significantly greater improvements in defensive functioning from pretreatment to six months posttreatment compared to the control group. GPIP may be effective for improving defensive functioning in individuals with BED. A randomized controlled trial is needed to confirm that GPIP is efficacious for addressing defensive functioning among women with BED.

Abstract
PURPOSE Emerging work indicates divergence in the neurobiologies of binge-eating disorder (BED) and obesity despite their frequent co-occurrence. This review highlights specific distinguishing aspects of BED, including elevated impulsivity and compulsivity possibly involving the mesocorticolimbic dopamine system, and discusses implications for differential therapeutics for BED. METHODS This narrative review describes epidemiologic, clinical, genetic, and preclinical differences between BED and obesity. Subsequently, this review discusses human neuroimaging work reporting differences in executive functioning, reward processing, and emotion reactivity in BED compared with obesity. Finally, on the basis of the neurobiology of BED, this review identifies existing and new therapeutic agents that may be most promising given their specific targets based on putative mechanisms of action relevant specifically to BED. FINDINGS BED is characterized by elevated impulsivity and compulsivity compared with obesity, which is reflected in divergent neurobiological characteristics and effective pharmacotherapies. Therapeutic agents that influence both reward and executive function systems may be especially effective for BED. IMPLICATIONS Greater attention to impulsivity/compulsivity-related, reward-related, and emotion reactivity-related processes may enhance conceptualization and treatment approaches for patients with BED. Consideration of these distinguishing characteristics and processes could have implications for more targeted pharmacologic treatment research and interventions.

Abstract
Eating disorders involve irregularities in eating behavior that may cause gastrointestinal (GI) symptoms. Consequently, many patients with eating disorders seek gastroenterological healthcare at some point in their illness, with many seeking this care even before they seek treatment for and/or diagnosed with their eating disorder. As such, the gastroenterology provider is in a unique position to identify, manage, and facilitate treatment for an eating disorder early in the course of the illness. Although assessing eating disorders is already a difficult task, the identification of eating disorders in patients with GI disease represents an even greater challenge. In particular, common GI symptoms, such as nausea, vomiting, and bloating, may disguise an eating disorder because these symptoms are often viewed as a sufficient impetus for dietary restriction and subsequent weight loss. In addition, the focus on identifying an organic etiology for the GI symptoms can distract providers from considering an eating disorder. During this prolonged diagnostic evaluation, the eating disorder can progress in severity and become more difficult to treat. Unfortunately, a misconception that hinders eating disorder detection is the notion that the rate or method of weight loss is associated with an eating disorder. Regardless of whether weight loss is slow or rapid, purposeful or accidental, eating disorder behaviors and thought patterns may be present. Unidentified eating disorders are not only dangerous in their own right but also can interfere with effective management of GI disease and its symptoms. As such, it is imperative for the GI provider to remain well versed in the identification of these diseases.

Abstract
Unhealthy diet and alcohol are serious health problems, especially in adolescents and young adults. "Binge" is defined as the excessive and uncontrolled consumption of food (binge eating) and alcohol (binge drinking). Both behaviors are frequent among young people and have a highly negative impact on health and quality of life. Several studies have explored the causes and risk factors of both behaviors, and the evidence concludes that there is a relationship between the two behaviors. In addition, some research postulates that binge eating is a precipitating factor in the onset and escalation of excessive alcohol consumption, while other studies suggest that alcohol consumption leads to excessive and uncontrollable food consumption. Given that no review has yet been published regarding the directionality between the two behaviors, we have set out to provide an upto- date overview of binge eating and binge drinking problems, analyzing their commonalities and differences, and their uni- and bidirectional associations. In addition, we explore the reasons why young people tend to engage in both behaviors and consider directions for future research and clinical implications.

Abstract
OBJECTIVE To evaluate the state of the literature for whether food addiction may warrant consideration as a distinct psychiatric disorder in the Diagnostic and Statistical Manual (DSM) using Blashfield et al.'s (1990; Comprehensive Psychiatry, 31(1), 15-19) five criteria. This framework was utilized because it has recently been applied to examine the diagnostic utility of several eating disorder phenotypes. The criteria are: (a) at least 50 journal articles published on the proposed syndrome in the past 10 years; (b) proposal of diagnostic criteria and assessment measures; (c) clinician reliability in diagnosis; (d) cohesiveness of the proposed diagnostic criteria; and (e) differentiation from similar, existing diagnostic categories. METHOD For each criterion, a literature review was conducted to examine if the minimum qualification had been met, and key findings were discussed. RESULTS Two of the criteria (literature and differentiation) have been empirically supported to extent specified. Two criteria (diagnostic criteria and syndrome) have been partially fulfilled, due to only having self-report assessment measures and no examination of the odds ratios for meeting more than one symptom, respectively. Clinician reliability has not yet been evaluated. DISCUSSION The existing literature suggests that food addiction may warrant consideration as a proposed diagnostic category in the DSM, though future research is needed to fulfill Blashfield et al.'s (1990; Comprehensive Psychiatry, 31(1), 15-19) criteria. The development of a semi-structured interview would be an impactful contribution for addressing these gaps.

Abstract
An update of the chapter on Mental, Behavioral and Neurodevelopmental Disorders in the International Classification of Diseases and Related Health Problems (ICD) is of great interest around the world. The recent approval of the 11th Revision of the ICD (ICD-11) by the World Health Organization (WHO) raises broad questions about the status of nosology of mental disorders as a whole as well as more focused questions regarding changes to the diagnostic guidelines for specific conditions and the implications of these changes for practice and research. This Forum brings together a broad range of experts to reflect on key changes and controversies in the ICD-11 classification of mental disorders. Taken together, there is consensus that the WHO's focus on global applicability and clinical utility in developing the diagnostic guidelines for this chapter will maximize the likelihood that it will be adopted by mental health professionals and administrators. This focus is also expected to enhance the application of the guidelines in non-specialist settings and their usefulness for scaling up evidence-based interventions. The new mental disorders classification in ICD-11 and its accompanying diagnostic guidelines therefore represent an important, albeit iterative, advance for the field.

Abstract
OBJECTIVE We aimed to understand the associations of compulsive eating (CE) and stress eating (SE) with metabolic health among adults with obesity and whether mindfulness-based weight loss training may buffer these associations. METHOD We used data from a trial in which we randomized 194 participants with obesity to a diet-exercise weight loss intervention with either mindful eating training plus mindfulness-based eating awareness and stress management training (n = 100) or active control components (n = 94). We measured CE, SE, weight, and fasting blood glucose (FBG) at baseline, and 6, 12 months, and 18 months. We tested CE and SE as both moderators and mediators of intervention effects on changes in metabolic health. RESULTS Participants higher (+ 1 SD) in CE at baseline randomized to the mindfulness (vs. control) intervention had greater improvements in FBG at 18 months (p = .05). Twelve-month reductions in CE mediated the effect of the intervention on changes in FBG and weight at 12 and 18 months postbaseline (p ≤ .05). Furthermore, those higher (+ 1 SD) in SE at baseline were nearly 2 BMI points higher than those lower (-1 SD) in SE (p < .01). Decreases in SE (B = 3.42; p < .001; 95% CI [2.55, 4.30]) and CE (B = 0.45; p < .001; 95% CI [0.36, 0.54]) in all participants at 6 months were associated with greater weight loss at 18 months. CONCLUSIONS Those with greater compulsive eating may reduce risk for metabolic decline by participating in a mindfulness-based weight loss program. Future obesity interventions should consider tailoring treatment toward trait-level characteristics, such as compulsive eating. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Abstract
OBJECTIVES The aim of this study was to conduct a systematic review of the literature to collect, analyse and synthesise the evidence on skin picking disorder as defined by Arnold's criteria or the Diagnostic and Statistical Manual of Mental Disorders - fifth edition (DSM-5) and to examine whether skin picking disorder warrants inclusion in the DSM-5 as a distinct disorder. METHOD The databases CINAHL, Medline, Embase and PsycINFO were searched for articles published between January 2008 and May 2018. Eligible articles were empirical studies that used Arnold's or DSM-5 criteria to diagnose skin picking disorder, published in English, with participants aged 18 years or older. The methodological quality of included studies was assessed according to the National Health and Medical Research Council's guidelines and suggested nosological classification of skin picking disorder were summarised. Eligible studies were assessed against the five criteria proposed by Blashfield and colleagues to determine the validity of the inclusion of skin picking disorder in the DSM-5. RESULTS A total of 20 studies were considered eligible out of 1554. Most of the papers were case-control studies with small clinical samples. Only one out of Blashfield's five criteria was met; there were commonly accepted diagnostic criteria and assessment scales present in the literature. However, at the time of review, the criterion of 50 published articles (25 of which are required to be empirical) was not met; there had been no publication specifically assessing the clinical utility or validity of skin picking disorder and no studies addressing the differentiation of skin picking disorder from other obsessive-compulsive and related disorders. CONCLUSION Only a small proportion of published studies on skin picking disorder have employed validated criteria. The current literature fulfills only one of Blashfield's five criteria for the inclusion of skin picking disorder as a specific entity in psychiatric diagnostic manuals. Further empirical studies on skin picking disorder are needed in order to substantiate skin picking disorder as a disorder distinct from related disorders under the obsessive-compulsive and related disorders category.

Abstract
Most theories emphasize the role of sociocultural factors in the etiology of eating disorders (EDs). This article uses a broad search strategy to identify current etiologic studies. Women with an ED outnumber men in each diagnosis, but gender differences vary by diagnosis. Men were underrepresented in study samples, and information about variable risk factors in men is sparse. Findings suggest transdiagnostic risk factors and disorder-specific risk factors. Extracting data from population-based registers represents a major advance. Novel analytic approaches suggest complex pathways to ED. Although used in several studies, reliance on a transdiagnostic ED category (vs diagnosis-specific groupings) is premature.

Abstract
BACKGROUND The efficacy and safety of Lisdexamfetamine dimesylate (LDX) in the treatment of moderate to severe binge eating disorder (BED) has been demonstrated in multiple randomised clinical trials. Despite this, little is known about how LDX acts to improve binge eating symptoms. This study aims to provide a comprehensive understanding of the neural mechanisms by which LDX improves symptoms of BED. We hypothesise that LDX will act by normalising connectivity within neural circuits responsible for reward and impulse control, and that this normalisation will correlate with reduced binge eating episodes. METHODS This is an open-label Phase 4 clinical trial of LDX in adults with moderate to severe BED. Enrolment will include 40 adults with moderate to severe BED aged 18-40 years and Body Mass Index (BMI) of 20-45 kg/m2, and 22 healthy controls matched for age, gender and BMI. Clinical interview and validated scales are used to confirm diagnosis and screen for exclusion criteria, which include comorbid anorexia nervosa or bulimia nervosa, use of psychostimulants within the past 6 months, and current use of antipsychotics or noradrenaline reuptake inhibitors. Baseline assessments include clinical symptoms, multimodal neuroimaging, cognitive assessment of reward sensitivity and behavioural inhibition, and an (optional) genetic sample. A subset of these assessments are repeated after eight weeks of treatment with LDX titrated to either 50 or 70 mg. The primary outcome measures are resting-state intrinsic connectivity and the number of binge eating episodes. Analyses will be applied to resting-state fMRI data to characterise pharmacological effects across the functional connectome, and assess correlations with symptom measure changes. Comparison of neural measures between controls and those with BED post-treatment will also be performed to determine whether LDX normalises brain function. DISCUSSION First enrolment was in May 2018, and is ongoing. This study is the first comprehensive investigation of the neurobiological changes that occur with LDX treatment in adults with moderate to severe BED.

Abstract
Binge eating disorder (BED) represents one of the most problematic clinical conditions among youths. Research has shown that the developmental stage of adolescence is a critical stage for the onset of eating disorders (EDs), with a peak prevalence of BED at the age of 16–17 years. Several studies among adults with BED have underlined that it is associated with a broad spectrum of negative consequences, including higher concern about shape and weight, difficulties in social functioning, and emotional-behavioral problems. This review aimed to examine studies focused on the prevalence of BED in the adolescent population, its impact in terms of physical, social, and psychological outcomes, and possible strategies of psychological intervention. The review of international literature was made on paper material and electronic databases ProQuest, PsycArticles, and PsycInfo, and the Scopus index were used to verify the scientific relevance of the papers. Epidemiological research that examined the prevalence of BED in adolescent samples in accordance with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition showed a prevalence ranging from 1% to 4%. More recently, only a few studies have investigated the prevalence of BED, in accordance with the Diagnostic and Statistical Manual of Disorders, Fifth Edition criteria, reporting a prevalence of ~1%–5%. Studies that focused on the possible impact that BED may have on physical, psychological, and social functioning showed that adolescents with BED have an increased risk of developing various adverse consequences, including obesity, social problems, substance use, suicidality, and other psychological difficulties, especially in the internalizing area. Despite the evidence, to date, reviews on possible and effective psychological treatment for BED among young population are rare and focused primarily on adolescent females.

Abstract
Binge eating disorder (BED) is characterized by recurrent binge eating and marked distress in the absence of inappropriate compensatory behaviors for weight control. BED is prevalent in men and women, is associated with elevated psychosocial and functional impairment, and is associated strongly with obesity and related medical comorbidities. The aim is to provide a brief, state-of-the-art review of the major and recent findings to inform educational and awareness campaigns, stigma reduction interventions, as well as current clinical practice and future research. A narrative approach was used to synthesize emerging literature on the public and healthcare professionals’ knowledge and attitudes toward individuals with BED in comparison to other eating disorders (EDs) or mental illness. A total of 13 articles were reviewed. Nine studies investigated community samples and four studies investigated healthcare professionals. The reviewed literature suggested that BED is perceived by the public as less impairing, less severe, and “easier-to-treat” than other EDs. Attitudes and beliefs reflecting perceived blameworthiness and lack of self-discipline were ascribed to vignettes with BED. Community studies indicated a low level of public awareness that BED constitutes a discreet eating disorder. The literature on healthcare professionals’ knowledge and attitudes toward BED remains very limited. The few existing studies suggest encouraging trends in recognition and diagnostic accuracy, yet there remains a need for increased clinical awareness of BED-associated medical complications and knowledge of full BED diagnostic criteria.

Abstract
The selective 5-HT2C receptor agonist lorcaserin entered clinical obesity trials with the prevalent view that satiety was a primary mechanism of action. Subsequent Phase II and III trials demonstrated efficacy in terms of weight loss, although the overall effect size (~3% placebo-corrected change) is considered modest. Lorcaserin has been approved by the FDA for the treatment of obesity with lifestyle modification, but since its introduction in 2013 its sales are in decline, probably due to its overall modest effect. However, in some individuals, lorcaserin has a much more clinically significant effect (i.e. >10% placebo-corrected change), although what common features, if any, define these high responders is presently unknown. In the present article we highlight the evidence that alternative mechanisms to satiety may contribute to the anti-obesity effect of lorcaserin, namely effects on constructs of primary and conditioned reward and impulsivity. This may better inform the clinical evaluation of lorcaserin (and any future 5-HT2C receptor agonists) to subgroups of obese subjects characterized by overeating due to maladaptive impulsivity and reward mechanisms. One such population might be individuals diagnosed with binge eating disorder.

Abstract
Studies indicate an attentional bias towards food in binge-eating disorder (BED); however, more evidence on attentional engagement and disengagement and processing of multiple attention-competing stimuli is needed. This study aimed to examine visual attention to food and non-food stimuli in BED. In n = 23 participants with full-syndrome and subsyndromal BED and n = 23 individually matched healthy controls, eye-tracking was used to assess attention to food and non-food stimuli during a free exploration paradigm and a visual search task. In the free exploration paradigm, groups did not differ in their initial fixation position. While both groups fixated non-food stimuli significantly longer than food stimuli, the BED group allocated significantly more attention towards food than controls. In the visual search task, groups did not differ in detection times. However, a significant detection bias for food was found in full-syndrome BED, but not in controls. An increased initial attention towards food was related to greater BED symptomatology and lower body mass index (BMI) only in full-syndrome BED, while a greater maintained attention to food was associated with lower BMI in controls. The results suggest food-biased visual attentional processing in adults with BED. Further studies should clarify the implications of attentional processes for the etiology and maintenance of BED.

Abstract
OBJECTIVE Although findings suggest that binge eating is becoming increasingly normative, the 'clinical significance' of this behaviour at a population level remains uncertain. We aimed to assess the time trends in binge-eating prevalence and burden over 18 years. METHOD Six cross-sectional face-to-face surveys of the Australian adult population were conducted in 1998, 2005, 2008, 2009, 2014, and 2015 (Ntotal = 15 126). Data were collected on demographics, 3-month prevalence of objective binge eating (OBE), health-related quality of life, days out of role, and distress related to OBE. RESULTS The prevalence of OBE increased six-fold from 1998 (2.7%) to 2015 (13.0%). Health-related quality of life associated with OBE improved from 1998 to 2015, where it more closely approximated population norms. Days out of role remained higher among participants who reported OBE, although decreased over time. Half of participants who reported weekly (56.6%) and twice-weekly (47.1%) OBE reported that they were not distressed by this behaviour. However, the presence of distress related to OBE in 2015 was associated with greater health-related quality-of-life impairment. CONCLUSION As the prevalence of binge eating increases over time, associated disability has been decreasing. Implications for the diagnosis of disorders associated with binge eating are discussed.

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
The objective of this study was to examine the relationship between overvaluation of weight/shape ('overvaluation') and emotion regulation (ER) difficulties among women with binge eating disorder (BED) symptoms. Four groups of women were recruited from a community-based sample and compared on ER difficulties: individuals with probable BED with (n=102) and without (n=72) overvaluation, and non-binge eating obese (n=40) and healthy-weight (n=40) control participants. Data for patients with a formal diagnosis of BED receiving treatment from a previous study were included for numerical comparative purposes. Women with probable BED and overvaluation reported significantly greater ER difficulties than all other groups and had similar levels of ER difficulties to BED patients. Women with probable BED in the absence of overvaluation were comparable to the obese control group on total ER difficulties and the majority of the ER difficulties subscales. The findings provide further evidence for the clinical significance of overvaluation among individuals with BED symptomatology. BED in the absence of overvaluation does not appear to align with current models of the disorder in which ER difficulties are viewed as a core etiological mechanism. Further research is needed to elucidate the status of this presentation.

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
OBJECTIVES We evaluated the effects of three doses of a behavioral intervention for obesity (High dose=24 sessions, Moderate=16 sessions, Low=8 sessions) compared with a nutrition education control group (Control) on binge eating. We also examined whether participants with clinically significant improvements in binge eating had better treatment adherence and weight-loss outcomes than those who did not experience clinically significant improvements in binge eating. Finally, we examined the relation of pretreatment binge eating severity to changes at six months. METHODS Participants included 572 adults (female=78.7%; baseline mean±SD: age=52.7±11.2years, BMI=36.4±3.9kg/m(2)) who provided binge eating data at baseline. We evaluated binge eating severity (assessed via the Binge Eating Scale) and weight status at baseline and six months, as well as treatment adherence over six months. RESULTS At six months, participants in the Moderate and High treatment conditions reported greater reductions in binge eating severity than participants in the Low and Control conditions, ps<.02. Participants who demonstrated improvements in binge eating severity reported greater dietary self-monitoring adherence and attained larger weight losses than those who did not experience clinically significant reductions, ps<.001. Pretreatment binge eating severity predicted less improvement in binge eating severity over six months and fewer days with dietary self-monitoring records completed, ps≤.002. CONCLUSION A moderate or high dose of behavioral weight-loss treatment may be required to produce clinically significant reductions in binge eating severity in adults with obesity.

Abstract
BACKGROUND Preliminary placebo-controlled evidence paved the ground to the US Food and Drug Administration approval extension of lisdexamfetamine for the treatment of moderate-to-severe binge eating disorder (BED) in adults. OBJECTIVES To provide a preliminary qualitative and quantitative synthesis of the placebo-controlled, randomized clinical trials (RCTs) considering the efficacy and tolerability of lisdexamfetamine in the acute and/or maintenance treatment of moderate-to-severe BED in adults. METHODS A preliminary, yet comprehensive, systematic review was performed by accessing a broad range of resources providing publicly available data about lisdexamfetamine at the time of inquiry (March 2016). Study eligibility criteria, participants, and interventions were considered focusing on major clinical and functional outcomes of either efficacy or tolerability of lisdexamfetamine in the treatment of moderate-to-severe BED in adults. RESULTS Meta-analysis of data pooled from three acute RCTs significantly favored lisdexamfetamine over placebo in the reduction of binge eating days/week, Yale-Brown Obsessive Compulsive Scale Modified for Binge Eating total score, weight, response, and remission rates (all, P≤0.01). In contrast, discontinuation rates due to treatment-emergent adverse events were significantly higher among patients in receipt of lisdexamfetamine (relative risk 2.19, P=0.04) versus placebo. LIMITATIONS Publication, selection, performance, attrition, reporting, sponsorship, and "diagnostic shift" biases. Lack of inclusion of adverse event effects other than those requiring discontinuation of the trial(s), as well as lack of information about clinically relevant psychiatric or other medical comorbidities, limits the overall generalizability of pooled results. CONCLUSION Across the included acute phase RCTs, lisdexamfetamine (at 30, 50, or 70 mg/day) led to significant reduction in a number of clinically relevant outcomes compared to placebo. Moreover, safety concerns related to adverse events, high discontinuation rates, and the need for additional long-term maintenance of RCTs solicit careful monitoring of the drug in terms of overall safety and tolerability by further RCTs.

Abstract
OBJECTIVES (1) To collect, analyze and synthetize the evidence on muscle dysmorphia diagnosis as defined by Pope et al. and (2) To discuss its appropriate nosology and inclusion as a specific category in psychiatric classificatory systems. METHOD A systematic search in the MEDLINE, the PsycNET, the LILACS and SciELO databases and in the International Journal of Eating Disorders was conducted looking for articles published between January 1997 and October 2014 and in EMBASE database between January 1997 and August 2013. Only epidemiological and analytical studies were considered for selection. The methodological quality of included studies was assessed according to the Evidence-Based Mental Health and the National Health and Medical Research Council's guidelines. The support for inclusion of muscle dysmorphia in psychiatric classificatory systems was examined against Blashfield et al.'s criteria. RESULTS Thirty-four articles were considered eligible out of 5136. Most of the studies were cross-sectional and enrolled small, non-clinical samples. The methodological quality of all selected papers was graded at the lowest hierarchical level due to studies' designs. Forty-one percent of the publications considered the available evidence insufficient to support the inclusion of muscle dysmorphia in any existing category of psychiatric disorders. The current literature does not fulfill Blashfield et al.'s criteria for the inclusion of muscle dysmorphia as a specific entity in psychiatric diagnostic manuals. CONCLUSION The current evidence does not ensure the validity, clinical utility, nosological classification and inclusion of muscle dysmorphia as a new disorder in classificatory systems of mental disorders.

Abstract
PURPOSE The current study evaluated whether or not there were significant differences in psychopathological traits between three groups of individuals. The first was a group of patients seeking bariatric surgery diagnosed as being affected by Binge Eating Disorder (BED), according to the new criteria of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. This group (NEW BED group) did not meet BED diagnosis following the previous criteria listed in the DSM-IV-TR. The second group of individuals was composed of severely obese patients seeking bariatric surgery not affected by an eating disorder, according to the diagnostic criteria of the DSM-5 (OB group). The third group was composed of individuals within a healthy weight range (Control group). METHODS 94 severely obese patients (33 in the NEW BED group and 61 in the OB group) were compared to the Control group including 41 participants on depression, anxiety and eating habits. RESULTS The NEW BED scored significantly higher than the OB group on the Beck Depression Inventory, both the subscales of the State Trait Anxiety Inventory, on disinhibition and hunger subscales of the Three-Factor Eating Questionnaire and on many subscales of the Eating Disorders Inventory. CONCLUSIONS The new, less restrictive diagnostic criteria for BED of the DSM-5 are useful in identifying obese patients affected by severe psychopathology and dysfunctional eating habits.

Abstract
Binge eating disorder is characterized by excessive, uncontrollable consumption of palatable food within brief periods of time. Excessive intake of palatable food is thought to be driven by hedonic, rather than energy homeostatic, mechanisms. However, reward processing does not only comprise consummatory actions; a key component is represented by the anticipatory phase directed at procuring the reward. This phase is highly influenced by environmental food-associated stimuli, which can robustly enhance the desire to eat even in the absence of physiological needs. The opioid system (endogenous peptides and their receptors) has been strongly linked to the rewarding aspects of palatable food intake, and perhaps represents the key system involved in hedonic overeating. Here we review evidence suggesting that the opioid system can also be regarded as one of the systems that regulates the anticipatory incentive processes preceding binge eating hedonic episodes.

Abstract
DSM-5 contains substantial changes to eating disorder diagnoses. We examined relative prevalence rates of DSM-IV and DSM-5 eating disorder diagnoses using Eating Disorder Examination-Questionnaire diagnostic algorithms in 117 community out-patients. DSM-5 criteria produced a reduction in combined 'other specified feeding or eating disorder' and 'unspecified feeding or eating disorder' from 46% to 29%, an increase in anorexia nervosa diagnoses from 35% to 47%, the same number of bulimia nervosa diagnoses and a 5% rate of binge eating disorder diagnoses.

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

Abstract
The major features in eating disorders are a preoccupation with food and its consumption and body dissatisfaction. Diagnostic manuals provide clusters of criteria according to which affected individuals can be categorized into one or other group of eating disorder. Yet, when considering the high proportion of comorbidities and ignoring the content of the symptoms (food, body), the major features seem to yield obsessional-compulsive, addictive, and impulsive qualities. In the present article, we review studies from the neuroscientific literature (mainly lesion studies) on eating disorder, obsessive-compulsive disorder, impulse control disorder, and addiction to investigate the possibility of a wider phenotype that can be related to a common brain network. The literature localizes this network to the right frontal lobe and its connectivities. This network, when dysfunctional, might result in a behavior that favors the preoccupation with particular thoughts, behaviors, anxieties, and uncontrollable urges that are accompanied by little scope for ongoing behavioral adjustments (e.g., impulse control). We reason that this network may turn out to be equally involved in understudied mental conditions of dysfunctional body processing such as muscle dysmorphia, body dysmorphic disorder (including esthetic surgery), and xelomelia. We finally consider previous notions of a wider phenotype approach to current diagnostic practice (using DSM), such as the possibility of a model with a reduced number of diagnostic categories and primary and secondary factors, and to etiological models of mental health conditions.

Abstract
BACKGROUND Although a wealth of studies have tested the link between negative mood states and likelihood of a subsequent binge eating episode, the assumption that this relationship follows a typical linear dose-response pattern (i.e., that risk of a binge episode increases in proportion to level of negative mood) has not been challenged. The present study demonstrates the applicability of an alternative, non-linear conceptualization of this relationship, in which the strength of association between negative mood and probability of a binge episode increases above a threshold value for the mood variable relative to the slope below this threshold value (threshold dose response model). METHODS A sample of 93 women aged 18 to 40 completed an online survey at random intervals seven times per day for a period of one week. Participants self-reported their current mood state and whether they had recently engaged in an eating episode symptomatic of a binge. RESULTS As hypothesized, the threshold approach was a better predictor than the linear dose-response modeling of likelihood of a binge episode. The superiority of the threshold approach was found even at low levels of negative mood (3 out of 10, with higher scores reflecting more negative mood). Additionally, severity of negative mood beyond this threshold value appears to be useful for predicting time to onset of a binge episode. CONCLUSIONS Present findings suggest that simple dose-response formulations for the association between negative mood and onset of binge episodes miss vital aspects of this relationship. Most notably, the impact of mood on binge eating appears to depend on whether a threshold value of negative mood has been breached, and elevation in mood beyond this point may be useful for clinicians and researchers to identify time to onset.

Abstract
OBJECTIVE Binge eating disorder (BED) was recently included in the DSM-5. The prevalence rate for BED using the DSM-IV-TR research criteria tends to be higher in bariatric surgery candidates than the normative population; however, no studies have examined how many more bariatric surgery candidates will meet the new, less conservative criteria of DSM-5. We explore the current BED prevalence rate change in a sample of bariatric surgery candidates. METHOD Data were obtained for 1,283 bariatric surgery candidates. 84 men and 213 women were diagnosed with current BED using DSM-IV-TR research criteria. A semi-structured interview, the binge eating scale (BES), and a Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) were given to every patient as part of standard procedures mandated by the facility. RESULTS AND DISCUSSION An additional 3.43% (p < .001) of bariatric surgery candidates met the diagnostic threshold for BED when using DSM-5 criteria. These individuals were demographical similar and produced similar MMPI-2-RF and BES scores when compared with patients who met DSM-IV-TR criteria for BED. Thus, the current investigation indicates that individuals meeting BED criteria based on DSM-5 are similar to those meeting the more conservative diagnostic threshold outlined in DSM-IV-TR in a sample of bariatric surgery candidates.

Abstract
Food has both homeostatic and hedonic components, which makes it a potent natural reward. Food related reward could therefore promote an escalation of intake and trigger symptoms associated to withdrawal, suggesting a behavioral parallel with substance abuse. Animal and human theoretical models of food reward and addiction have emerged, raising further interrogations on the validity of a bond between Substance Use Disorders, as clinically categorized in the DSM 5, and food reward. These models propose that highly palatable food items, rich in sugar and/or fat, are overly stimulating to the brain's reward pathways. Moreover, studies have also investigated the possibility of causal link between food reward and the contemporary obesity epidemic, with obesity being potentiated and maintained due to this overwhelming food reward. Although natural rewards are a hot topic in the definition and categorization of Substance Use Disorders, proofs of concept and definite evidence are still inconclusive. This review focuses on available results from experimental studies in animal and human models exploring the concept of food addiction, in an effort to determine if it depicts a specific phenotype and if there is truly a neurobiological similarity between food addiction and Substance Use Disorders. It describes results from sugar, fat and sweet-fat bingeing in rodent models, and behavioral and neurobiological assessments in different human populations. Although pieces of behavioral and neurobiological evidence supporting a food addiction phenotype in animals and humans are interesting, it seems premature to conclude on its validity.

Abstract
Background. Cross-national population data from the WHO World Mental Health surveys are used to compare role attainments and role impairments associated with binge-eating disorder (BED) and bulimia nervosa (BN). Methods. Community surveys assessed 23 000 adults across 12 countries for BED, BN and ten other DSM-IV mental disorders using the WHO Composite International Diagnostic Interview. Age-of-onset was assessed retrospectively. Ten physical disorders were assessed using standard conditions checklists. Analyses examined reciprocal time-lagged associations of eating disorders (EDs) with education, associations of early-onset (i.e., prior to completing education) EDs with subsequent adult role attainments and cross-sectional associations of current EDs with days of role impairment. Results. BED and BN predicted significantly increased education (females). Student status predicted increased risk of subsequent BED and BN (females). Early-onset BED predicted reduced odds of current (at time of interview) marriage (females) and reduced odds of current employment (males). Early-onset BN predicted increased odds of current work disability (females and males). Current BED and BN were both associated with significantly increased days of role impairment (females and males). Significant BED and BN effects on adult role attainments and impairments were explained by controls for comorbid disorders. Conclusions. Effects of BED on role attainments and impairments are comparable with those of BN. The most plausible interpretation of the fact that these associations are explained by comorbid disorders is that causal effects of EDs are mediated through secondary disorders. Controlled treatment effectiveness studies are needed to trace out long-term effects of BED-BN on secondary disorders.

Personality disorders in eating disorder not otherwise specified and binge eating disorder: a meta-analysis of comorbidity studies. J Nerv Ment Dis 2014; 202:119-25.

Abstract
A meta-analysis was conducted to identify the proportion of comorbid personality disorders (PDs) in patients with eating disorder not otherwise specified (EDNOS) and binge eating disorder (BED). A search identified 20 articles in the period of 1987 to 2010. For EDNOS and BED, the comorbid proportions for any PD were 0.38 and 0.29, respectively; for cluster C PDs, 0.38 and 0.30, respectively (avoidant PD, 0.18 and 0.12, and obsessive-compulsive PD, 0.11 and 0.10, respectively); and for cluster B PDs, 0.25 and 0.11, respectively (borderline, 0.12 and 0.10). This pattern converged with findings on anorexia nervosa and bulimia nervosa, except being lower. Because the comorbidity profiles for EDNOS and BED were highly similar, their underlying PD pathology seems similar. Few moderators were significant, except for interviews yielding lower estimates than that of questionnaires. The variance statistic for any PD comorbidity was wide for EDNOS and narrow for BED, thus partly supporting BED as a distinct eating disorder category and EDNOS as a potentially more severe condition than BED.

Abstract
ABSTRACT Eating disorders often develop during adolescence and young adulthood, and are associated with significant psychological and physical burden. Identifying evidence-based interventions is critical and there is need to take stock of the extant literature, to inform clinical practice regarding well-researched interventions and to direct future research agendas by identifying gaps in the evidence base. AIM To investigate and quantify the nature and distribution of existing high-quality research on the prevention and treatment of eating disorders in young people using evidence mapping methodology. METHOD A systematic search for prevention and treatment intervention studies in adolescents and young adults (12-25 years) was conducted using EMBASE, PSYCINFO and MEDLINE. Studies were screened and mapped according to disorder, intervention modality, stage of eating disorder and study design. Included studies were restricted to controlled trials and systematic reviews published since 1980. RESULTS The eating disorders evidence map included 197 trials and 22 systematic reviews. Prevention research was dominated by trials of psychoeducation (PE). Bulimia nervosa (BN) received the most attention in the treatment literature, with cognitive behavioural therapy (CBT) and antidepressants the most common interventions. For anorexia nervosa (AN), family based therapy (FBT) was the most studied. Lacking were trials exploring treatments for binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS). Relapse prevention strategies were notably absent across the eating disorders. CONCLUSIONS Despite substantial literature devoted to the prevention and treatment of eating disorders in young people, the evidence base is not well established and significant gaps remain. For those identified as being at-risk, there is need for prevention research exploring strategies other than passive PE. Treatment interventions targeting BED and EDNOS are required, as are systematic reviews synthesising BN treatment trials (e.g., CBT, antidepressants). FBTs for AN require investigation against other validated psychological interventions, and the development of relapse prevention strategies is urgently required. By systematically identifying existing interventions for young people with eating disorders and exposing gaps in the current literature, the evidence map can inform researchers, funding bodies and policy makers as to the opportunities for future research.

Abstract
Background Binge eating disorder (BED) represents a distinct eating disorder diagnosis. Current approaches assume increased impulsivity to be one factor leading to binge eating and weight gain. We used eye tracking to investigate both components of impulsivity, namely reward sensitivity and rash-spontaneous behaviour towards food in BED for the first time. Methods Overweight and obese people with BED (BED+; n = 25), without BED (BED−; n = 26) and healthy normal-weight controls (NWC; n = 25) performed a free exploration paradigm measuring reward sensitivity (experiment 1) and a modified antisaccade paradigm measuring disinhibited, rash-spontaneous behaviour (experiment 2) using food and nonfood stimuli. Additionally, trait impulsivity was assessed. Results In experiment 1, all participants located their initial fixations more often on food stimuli and BED+ participants gazed longer on food stimuli in comparison with BED− and NWC participants. In experiment 2, BED+ participants had more difficulties inhibiting saccades towards food and nonfood stimuli compared with both other groups in first saccades, and especially towards food stimuli in second saccades and concerning sequences of first and second saccades. BED− participants did not differ significantly from NWC participants in both experiments. Additionally, eye tracking performance was associated with self-reported reward responsiveness and self-control. Conclusions According to these results, food-related reward sensitivity and rash-spontaneous behaviour, as the two components of impulsivity, are increased in BED in comparison with weight-matched and normal-weight controls. This indicates that BED represents a neurobehavioural phenotype of obesity that is characterised by increased impulsivity. Interventions for BED should target these special needs of affected patients.

Abstract
BACKGROUND Little population-based data exist outside the United States on the epidemiology of binge eating disorder (BED). Cross-national BED data are presented here and compared with bulimia nervosa (BN) data in the World Health Organization (WHO) World Mental Health Surveys. METHODS Community surveys with 24,124 respondents (ages 18+) across 14 mostly upper-middle and high-income countries assessed lifetime and 12-month DSM-IV mental disorders with the WHO Composite International Diagnostic Interview. Physical disorders were assessed with a chronic conditions checklist. RESULTS Country-specific lifetime prevalence estimates are consistently (median; interquartile range) higher for BED (1.4%; .8-1.9%) than BN (.8%; .4-1.0%). Median age of onset is in the late teens to early 20s for both disorders but slightly younger for BN. Persistence is slightly higher for BN (6.5 years; 2.2-15.4) than BED (4.3 years; 1.0-11.7). Lifetime risk of both disorders is elevated for women and recent cohorts. Retrospective reports suggest that comorbid DSM-IV disorders predict subsequent onset of BN somewhat more strongly than BED and that BN predicts subsequent comorbid disorders somewhat more strongly than does BED. Significant comorbidities with physical conditions are due almost entirely to BN and to a somewhat lesser degree BED predicting subsequent onset of these conditions. Role impairments are similar for BN and BED. Fewer than half of lifetime BN or BED cases receive treatment. CONCLUSIONS Binge eating disorder represents a public health problem at least equal to BN. Low treatment rates highlight the clinical importance of questioning patients about eating problems even when not included among presenting complaints.

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

Abstract
OBJECTIVE This study was a randomized placebo-controlled trial testing the addition of orlistat to behavioral weight loss for obesity in Spanish-speaking-only Latino/as with versus without binge eating disorder (BED) performed at a community mental health center serving educationally- and economically-disadvantaged patients. Latino/as have high rates of obesity but are under-represented in obesity treatment studies and despite comparable-to-or-higher rates of BED than Whites, Latino/as are under-represented in BED treatment studies. BED is associated with obesity but whether it predicts/moderates treatment outcomes remains uncertain. Thus, this study also tested whether BED prospectively predicts/moderates outcomes. METHODS Seventy-nine obese Spanish-speaking-only Latino/as with BED (N=40) versus without BED (N=39) at a community mental health center were randomly assigned to four-months of orlistat-plus-BWL or placebo-plus-BWL. BWL was culturally-enhanced modification of Diabetes-Prevention-Program delivered in weekly sessions in Spanish. Orlistat (120 mg tid) and matching-placebo delivered with standard clinical-management. Participants were assessed independently throughout treatment, post-treatment, and six-month follow-up. RESULTS 78% completed treatments; completion rates did not differ significantly by medication or BED. Intent-to-treat mixed-models analyses revealed significant improvements in binge eating, eating-psychopathology, and depression, and significant--albeit modest--weight-loss. Overall, the addition of orlistat to BWL was not associated with greater improvements; however, BED moderated weight-loss: orlistat-plus-BWL produced significantly greater weight-loss in non-BED group but not in BED. Improvements were maintained through 6-month follow-up; BED significantly predicted/moderated increases in eating concerns and depression following treatment. Within BED-group, binge-eating remission rates were 65% (post-treatment) and 50% (follow-up). CONCLUSIONS In this controlled trial performed at community mental health center serving educationally- and economically-disadvantaged Spanish-speaking-only Latino/as with co-morbid psychiatric needs, we observed outcomes for the BWL plus orlistat/placebo medication that approximate or are slightly dampened relative to the literature for efficacy trials with much more restrictive obese and BED samples. In this complex patient group, adding orlistat to BWL produced greater weight-loss than adding placebo among obese patients without BED but not among those with BED. Although 50% of BED patients maintained abstinence from binge-eating following these specific obesity treatments (BWL plus orlistat/placebo), BED was a negative prognostic indicator for some outcome variables.
