Abstract
Eating disorders (EDs) are highly comorbid with obsessive-compulsive disorder (OCD), with comorbidity rates as high as 41%. In the current review, we summarize the literature regarding the prevalence of ED-OCD comorbidity. We also identify and review the literature assessing shared features (i.e., shared characteristics or symptoms) and mechanisms (i.e., variables that may explain ED or OCD symptoms) of EDs and OCD. Potential shared features of EDs and OCD include age of onset, course of illness, obsessions, compulsions and ritualistic behaviors, and thought action fusion. Shared mechanisms that may explain ED-OCD comorbidity include genetic and neurobiological mechanisms, anxiety and fear, repetitive negative thinking, perfectionism, intolerance of uncertainty, distress tolerance, and impulsivity. Based on these shared features and mechanisms, a theoretical conceptualization of ED and OCD comorbidity is developed, and outline considerations for assessment, differential diagnosis, treatment, and future research regarding ED-OCD comorbidity are described.

Abstract
Binge eating disorder (BED), characterized by bingeing episodes and compulsivity, is the most prevalent eating disorder; however, little is known about its neurobiological underpinnings. In humans, BED is associated with desensitization of the reward system, specifically, the medial prefrontal cortex (mPFC), nucleus accumbens (Acb), and ventral tegmental area (VTA). Additionally, BED patients feel relieved during bingeing, suggesting that bingeing helps to decrease the negative emotions they were feeling prior to the binge episode. However, the mechanisms that underlie this feeling of relief in BED patients have not been well investigated. To investigate neuronal activity before and during palatable food consumption in BED, we performed in vivo electrophysiological recordings in a binge-like eating rat model (bingeing, n = 12 and non-bingeing, n = 14) and analyzed the firing rate of neurons in the mPFC, Acb, and VTA before and during access to sucrose solution. We also investigated changes in the firing rate of neurons in these regions during and between active bingeing, which may underlie the feeling of relief in BED patients. We found that neuronal firing rates of mPFC and VTA neurons in bingeing rats were lower than those in non-bingeing rats before and during sucrose consumption. Palatable food consumption increased neuronal firing rates during and between active bingeing in bingeing rats. Our results suggest a desynchronization in the activity of reward system regions, specifically in the mPFC, in bingeing rats, which may also contribute to BED. These results are consistent with those of functional magnetic resonance imaging (fMRI) studies that reported decreased activity in the reward system in BED patients. We propose that increased neuronal activity in the mPFC, Acb, or VTA produces an antidepressant effect in rats, which may underlie the sense of relief patients express during bingeing episodes.

Abstract
The present study aimed to provide a precise, meta-analytic estimate of the prevalence of obsessive-compulsive disorder (OCD) amongst those with a current primary eating disorder (ED) diagnosis, and to isolate its predictors. An online search of PubMed and PsycINFO was conducted with a Boolean search phrase incorporating keywords related to OCD, EDs, comorbidity, prevalence, and epidemiology, complemented by references coded from related review articles and contact with experts in the field. Articles were included if they (a) reported an observational study examining current ED diagnoses, (b) used a semi-structured or structured diagnostic interview for OCD and ED diagnosis, (c) applied DSM or ICD criteria, (d) included adolescent or adult samples (age > 12), (e) included patient or community samples, and (f) reported lifetime or current OCD comorbidity. From the 846 articles identified, 35 lifetime and 42 current estimates were calculated. OCD prevalence was extracted from each study for each ED diagnostic category, along with eleven additional potential moderators. Analyses revealed an aggregate lifetime OCD prevalence of 13.9% CI95% [10.4 to 18.1] and current OCD prevalence of 8.7% CI95% [5.8 to 11.8] across EDs. Moderator analyses revealed the prevalence of and risk for OCD in EDs to be greatest in anorexia nervosa binge-eating purging type (ANBP). Further, OCD is most prevalent amongst patient samples than samples recruited from the community.

Abstract
Altered functioning of the inhibition system and the resulting higher impulsivity are known to play a major role in overeating. Considering the great impact of disinhibited eating behavior on obesity onset and maintenance, this systematic review of the literature aims at identifying to what extent the brain inhibitory networks are impaired in individuals with obesity. It also aims at examining whether the presence of binge eating disorder leads to similar although steeper neural deterioration. We identified 12 studies that specifically assessed impulsivity during neuroimaging. We found a significant alteration of neural circuits primarily involving the frontal and limbic regions. Functional activity results show BMI-dependent hypoactivity of frontal regions during cognitive inhibition and either increased or decreased patterns of activity in several other brain regions, according to their respective role in inhibition processes. The presence of binge eating disorder results in further aggravation of those neural alterations. Connectivity results mainly report strengthened connectivity patterns across frontal, parietal, and limbic networks. Neuroimaging studies suggest significant impairment of various neural circuits involved in inhibition processes in individuals with obesity. The elaboration of accurate therapeutic neurocognitive interventions, however, requires further investigations, for a deeper identification and understanding of obesity-related alterations of the inhibition brain system.

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

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

Abstract
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
BACKGROUND There are a number of factors commonly believed to be important to the development and maintenance of binge eating that have been identified across multiple models and theories in the psychological literature. In the present study, we sought to develop and test a psychological model for binge eating that incorporated the main variables identified in the literature to drive binge eating behaviour; specifically, core low self-esteem, negative affect, difficulty with emotional regulation, restricted eating and beliefs about eating. METHODS Questionnaire data was collected from 760 unselected participants. The proposed model of binge eating was developed, bivariate relationships between the included variables were assessed, and the goodness-of-fit of this new model was evaluated using structural equations modelling. RESULT The results identified significant bivariate relationships between all the included variables. While the originally proposed model did not provide a good fit to the data, the revised version of the model provided a good fit to the data. CONCLUSIONS Supporting, integrating and building upon the current existing psychological models of binge eating, this study presents a new integrated cognitive and behavioural model of binge eating. The dual-pathway to binge eating identified in the new model provides a different way to understand transdiagnostic binge eating.

Beliefs about Binge Eating: Psychometric Properties of the Eating Beliefs Questionnaire (EBQ-18) in Eating Disorder, Obese, and Community Samples. Nutrients 2018; 10:E1306.

Abstract
Binge eating is a core diagnostic feature of bulimia nervosa, binge eating disorder, anorexia nervosa binge/purge type, and is a common feature of "other specified" and "unspecified" feeding and eating disorders. It has been suggested that specific metacognitive beliefs about food, eating, and binge eating may play a key role in the maintenance of binge eating behaviour. The Eating Beliefs Questionnaire (EBQ-18) provides a brief self-report assessment tool measuring three types of metacognitive beliefs: negative, positive, and permissive beliefs about food and eating. This study aimed to build on past research by validating the factor structure and psychometric properties of the EBQ-18 using both a clinical and non-clinical sample. A sample of 688 participants (n = 498 non-clinical participants, n = 161 participants seeking treatment for an eating disorder, and n = 29 participants seeking treatment for obesity) completed a battery of questionnaires, including the EBQ-18 and other measures of eating disorder symptoms and relevant constructs. A subset of 100 non-clinical participants completed the test battery again after an interval of two-weeks, and 38 clinical participants completed the EBQ-18 before and after receiving psychological treatment for their eating disorder. A confirmatory factor analysis (CFA) was conducted and psychometric properties of this measure were assessed. The results of this study provide support for the three-factor model of the EBQ-18. In addition, the EBQ-18 was found to be a valid and reliable measure, with excellent internal consistency, good test-retest reliability in the non-clinical sample, and also demonstrated evidence of sensitivity to treatment in clinical samples with binge eating pathology. Receiver operating characteristic (ROC) curve analyses were used to identify optimal cut-off scores for the EBQ-18. This study provides valuable information about the utility of the EBQ-18 as a measure for use in both clinical and research settings.

Abstract
BACKGROUND The Eating Beliefs Questionnaire (EBQ) is a self-report assessment tool that measures positive and negative beliefs about food and eating that are believed to play a key role in maintaining binge eating behaviour that occurs in individuals with Bulimia Nervosa, Binge Eating Disorder and other atypical eating disorders. The present study aimed to further refine this measure with the addition of a third scale to assess permissive beliefs about eating, also thought to play a crucial role in the maintenance of binge eating. Permissive beliefs are defined as beliefs about eating that provide justification for the individual to engage in a binge eating episode. METHODS After consultation with the literature and endorsement from 10 experts in eating disorders, 19 permissive belief items were generated. Eight hundred eighty-three participants were recruited to complete a test battery online that included the EBQ and the new permissive items. RESULTS An exploratory factor analysis (n = 441) found a three-factor solution (positive, negative and permissive beliefs) explaining 63.4% of variance. A confirmatory factor analysis (n = 442) provided support for the three-factor model, with the data best supporting a shorter 18-item questionnaire. The revised scale demonstrated good internal consistency, as well as good convergent validity with measures of related eating disorder symptoms, emotional regulation, mood and anxiety. CONCLUSIONS With the addition of a third scale to measure permissive beliefs, the revised short-form of the EBQ offers clinicians and researchers a brief comprehensive tool for the measurement of positive, negative and permissive beliefs about binge eating.

Abstract
Binge eating is a distressing symptom common to bulimia nervosa (BN), anorexia nervosa binge/purge subtype (AN-BP) and binge-eating disorder (BED). Over the last 40 years, many attempts have been made to conceptualise this symptom in terms of its antecedents, function, triggers, consequences, and maintaining factors. Cognitive theories of binge eating have evolved as new evidence has emerged. This literature review summarises the main and most influential cognitive models of binge eating across different eating disorder presentations. Many theories have examined binge eating in the context of restriction or compensatory behaviours, as is often observed in cases of BN. Few theories have examined binge eating as it occurs in BED specifically. The long-term efficacy of cognitive behavioural therapy (CBT) treatment based on these models leaves much to be desired, and indicates that there may be maintaining factors of binge eating not addressed in the typical CBT treatment for eating disorders. More recent cognitive models of binge eating propose possible maintaining beliefs, but further study is required to validate these models. Suggestions for future research are presented.

[PMID: 28245061 DOI: 10.1002/eat.22696] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2017] [Revised: 02/06/2017] [Accepted: 02/10/2017] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To test both the concurrent and predictive significance of the new DSM-5 severity specifier for binge-eating disorder (BED) in adult outpatients. METHOD Existing data from 195 adults with DSM-5 BED who received evidence-based treatment (manual-based cognitive-behavioral therapy) in an outpatient setting were re-analysed to examine whether these patients sub-grouped according to the DSM-5 severity levels, defined by the frequency of binge-eating (BE) episodes, would show meaningful differences in a range of variables of clinical interest assessed at pre-treatment and end-of treatment abstinence from BE. RESULTS Participants categorized with mild (33.3% of the sample), moderate (35.4%), severe (15.9%), and extreme (15.4%) severity of BED, based on their pre-treatment clinician-rated frequency of BE episodes, differed significantly from each other in physical characteristics (body mass index) and another sixteen variables of clinical interest assessed at pre-treatment regarding eating disorder psychopathology and putative maintenance factors, lifetime and current psychiatric disorder comorbidity, general psychiatric distress, and psychosocial impairment. The four DSM-5 severity groups were statistically indistinguishable in demographics or age-of-BED onset. However, significant between-group differences were observed in the treatment outcome, i.e., abstinence from BE, achieved by 98.5%, 66.7%, 38.7% and 6.7% of participants categorized with mild, moderate, severe, and extreme severity respectively. The outcome analyses repeated in the completer sample (n = 187) yielded the same pattern of the aforementioned intent-to-treat (N = 195) results. DISCUSSION The findings provide support for the severity specifier for BED introduced in the DSM-5 as a means of addressing within-group variability in severity.

Abstract
Little is known about personality disorders (PD) and comorbidities among Latinas with eating disorders (ED). The dysregulation and chronicity of PDs can complicate and augment the symptomatology of EDs. This set of analyses provides a preliminary examination of PD and psychopathology in a sample of Latina women with ED. Participants (N = 34) were administered the Structured Clinical Interview for the Diagnostic and Statistical Manual, Eating Disorders Examination, and Millon Clinical Multiaxial Inventory-III to assess personality pathology, and questionnaires (Beck Depression Inventory-II and Brief Symptom Inventory) to assess psychological functioning. Results indicated the most common clinically significant trait in the sample was depressive personality (50% of the sample had a score of 75 or higher on this trait). For Bulimia Nervosa (BN) and Binge Eating Disorder (BED), avoidant (41%) and depressive (65%) personalities, respectively, were the most common clinically significant traits. Anxiety disorders were the most common psychiatric diagnoses, and 52.9% of the sample reported both clinically significant PD traits and other major psychopathology. There were no significant differences between the BED and BN groups on prevalence of PD traits and psychopathology. This pilot study highlights the need for further examination of PD and psychopathology in Latinas with ED. Unlike previous research with White women, we found no differences on PD and psychopathology between BED and BN, and the most prevalent PDs among Latinas were different than White women. Personality and psychological functioning should be assessed in all patients with ED, with ongoing research focused on identifying patterns in understudied groups such as Latinas, a practice that may improve treatment for this underserved population.

Pathological Overeating: Emerging Evidence for a Compulsivity Construct. Neuropsychopharmacology 2017; 42:1375-1389.

Abstract
Compulsive eating behavior is a transdiagnostic construct that is characteristic of medical and psychiatric conditions such as forms of obesity and eating disorders. Although feeding research is moving toward a better understanding of the proposed addictive properties of food, the components and the mechanisms contributing to compulsive eating are not yet clearly defined or understood. Current understanding highlights three elements of compulsive behavior as it applies to pathological overeating: (1) habitual overeating; (2) overeating to relieve a negative emotional state; and (3) overeating despite aversive consequences. These elements emerge through mechanisms involving pathological habit formation through an aberrant learning process, the emergence of a negative emotional state, and dysfunctions in behavioral control. Dysfunctions in systems within neurocircuitries that comprise the basal ganglia, the extended amygdala, and the prefrontal cortex result in compulsive eating behaviors. Here, we present evidence to relate compulsive eating behavior and addiction and to characterize their underlying neurobiological mechanisms. A major need to improve understanding of compulsive eating through the integration of complex motivational, emotional, and cognitive constructs is warranted.

Abstract
Understanding the food choice decision-making may help identify those at higher risk for excess weight gain and dysregulated eating patterns. This paper systematically reviews the literature related to eating behavior and behavioral economic constructs of relative reinforcing value of food (RRVfood) and delayed reward discounting (DRD). RRVfood characterizes how valuable energy-dense food is to the individual, and DRD characterizes preferences for smaller immediate rewards over larger future rewards, an index of impulsivity. Literature search on PubMed was conducted using combination of terms that involve behavioral economics and dysregulated eating in youth and adults. Forty-seven articles were reviewed. There is consistent evidence that obese youth and adults exhibit higher RRVfood. There is a need for more research on the role of RRVfood in eating disorders, as an insufficient number of studies exist to draw meaningful conclusions. There is accumulating evidence that obese individuals have higher DRD but the study of moderators of this relationship is crucial. Only a small number of studies have been conducted on DRD and binge eating, and no clear conclusions can be made currently. Approximately half of existing studies suggest lower DRD in individuals with anorexia nervosa. Research implications and treatment application are discussed.

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

Abstract
BACKGROUND We linked extensive longitudinal data from the Swedish national eating disorders quality registers and patient registers to explore clinical characteristics at diagnosis, diagnostic flux, psychiatric comorbidity, and suicide attempts in 850 individuals diagnosed with binge-eating disorder (BED). METHOD Cases were all individuals who met criteria for BED in the quality registers (N = 850). We identified 10 controls for each identified case from the Multi-Generation Register matched on sex, and year, month, and county of birth. We evaluated characteristics of individuals with BED at evaluation and explored diagnostic flux across eating disorders presentations between evaluation and one-year follow-up. We applied conditional logistic regression models to assess the association of BED with each comorbid psychiatric disorder and with suicide attempts and explored whether risk for depression and suicide were differentially elevated in individuals with BED with or without comorbid obesity. RESULTS BED shows considerable diagnostic flux with other eating disorders over time, carries high psychiatric comorbidity burden with other eating disorders (OR 85.8; 95 % CI: 61.6, 119.4), major depressive disorder (OR 7.6; 95 % CI: 6.2, 9.3), bipolar disorder (OR 7.5; 95 % CI: 4.8, 11.9), anxiety disorders (OR 5.2; 95 % CI: 4.2, 6.4), and post-traumatic stress disorder (OR 4.3; 95 % CI: 3.2, 5.7) and is associated with elevated risk for suicide attempts (OR 1.8; 95 % CI: 1.2, 2.7). Depression and suicide attempt risk were elevated in individuals with BED with and without comorbid obesity. CONCLUSIONS Considerable flux occurs across BED and other eating disorder diagnoses. The high psychiatric comorbidity and suicide risk underscore the severity and clinical complexity of BED.

Abstract
This study aimed to extend the literature by examining several psychological factors (i.e. depression, anxiety, and stress) in relation to binge eating. Data were collected via online surveys from a community sample of men and women of diverse backgrounds. The main study hypotheses were supported, indicating a unique relation between anxiety and binge eating, and between stress and binge eating, independent of the impact of depression. Gender differences are discussed. The results of this study suggest a need for a more detailed examination of negative affect in binge eating. Furthermore, the role of anxiety may be important for future research.

Abstract
There is utility in understanding the antecedents of binge eating (BE), with a view to explaining poorer weight loss treatment responses in this subgroup. A systematic review was completed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with the aim of exploring associations between emotions and eating behaviour in a population affected by obesity and binge eating disorder (BED). A comprehensive literature search of four electronic databases (2004-2014) yielded 15 studies for inclusion. Included studies performed poorly on data quality analysis with respect to controlling for confounding variables, and sample size. Included papers largely focused on negative emotions as antecedents of BE; depression was consistently associated with a BED-obese classification and BE. Negative mood, sadness, tension and instability of emotions were found to be antecedents of BE in an adult BED-obese sample. However, findings were mixed regarding the role of stress, anger and positive emotions within the BED-obese population. Recommendations are presented for the identification of BED, and ecologically valid experimental designs that further understanding of the complex and varied emotions that associate with BE. The implications of these and other limitations for both researchers and practitioners are discussed. The paper concludes with recommendations for future research alongside suggestions for practitioners. © 2015 World Obesity.

Abstract
Psychiatric comorbidity is common in patients with eating disorders (ED), but prevalence estimates are heterogeneous, probably due to methodological differences between studies (population, diagnostic method, sampling procedure etc.) and a few studies include men. The aim of this study is to investigate psychiatric DSM-IV Axis I comorbidity in a large sample of adult patients, both males and females, with the whole spectrum of DSM-IV ED diagnoses. Initial presentation assessment data on 11,588 adult men and women presenting to specialist ED clinics in Sweden between 2008 and 2012 were extracted from a large clinical database. Diagnostics were based on semi-structured interviews (SCID-I) and the Structured Eating Disorder Interview (SEDI). Seventy-one percent of the patients with ED had at least one other Axis I disorder. The most common type of diagnosis was anxiety disorders (53%), where generalized anxiety disorder was the most common diagnosis. The highest levels of comorbidity were found for women with Binge Eating Disorder (BED) and men with Bulimia Nervosa (BN). Findings are consistent with previous research showing a high prevalence of psychiatric comorbidity in both men and women with ED. The small gender differences observed seem negligible compared to the general similarity in comorbidity.

Abstract
OBJECTIVE Understanding the factors that predict a favourable outcome following specialist treatment for an eating disorder may assist in improving treatment efficacy, and in developing novel interventions. This review and meta-analysis examined predictors of treatment outcome and drop-out. METHOD A literature search was conducted to identify research investigating predictors of outcome in individuals treated for an eating disorder. We organized predictors first by statistical type (simple, meditational, and moderational), and then by category. Average weighted mean effect sizes (r) were calculated for each category of predictor. RESULTS The most robust predictor of outcome at both end of treatment (EoT) and follow-up was the meditational mechanism of greater symptom change early during treatment. Simple baseline predictors associated with better outcomes at both EoT and follow-up included higher BMI, fewer binge/purge behaviors, greater motivation to recover, lower depression, lower shape/weight concern, fewer comorbidities, better interpersonal functioning and fewer familial problems. Drop-out was predicted by more binge/purge behaviors and lower motivation to recover. For most predictors, there was large interstudy variability in effect sizes, and outcomes were operationalized in different ways. There were generally insufficient studies to allow analysis of predictors by eating disorder subtype or treatment type. DISCUSSION To ensure that this area continues to develop with robust and clinically relevant findings, future studies should adopt a consistent definition of outcome and continue to examine complex multivariate predictor models. Growth in this area will allow for stronger conclusions to be drawn about the prediction of outcome for specific diagnoses and treatment types.

Abstract
OBJECTIVE Binge-eating disorder (BED) is associated with elevated rates of mood and substance use disorders, but the significance of such comorbidity is ambiguous. We compared personality disorder and eating disorder psychopathology in four subgroups of BED patients: those with mood disorders, those with substance use disorders, those with both, and those with neither. METHOD Subjects were 347 patients who met DSM-IV research criteria for BED. Semistructured interviews evaluated lifetime DSM-IV axis I disorders, DSM-IV personality disorder features, and eating disorder psychopathology. RESULTS Among these patients, 129 had co-occurring mood disorder, 34 had substance use disorder, 60 had both, and 124 had neither. Groups differed on personality disorder features, with those having mood disorder and both mood and substance use disorders showing the highest frequencies. Although groups did not differ in body mass index or binge eating frequency, they did differ on eating disorder psychopathology-with the groups having mood disorder and both comorbidities demonstrating higher eating, weight, and shape concerns. No differences were observed between groups with respect to ages of onset for specific eating behaviors, but some differences were observed for ages of disorder onset. CONCLUSION Mood and substance use disorders co-occur frequently among patients with BED. Compared with a previous work, the additional comparison group (those with both mood and substance use disorders) and the control group (those with neither) afforded better discrimination regarding the significance of these comorbidities. Our findings suggest approaches to subtyping BED based on psychiatric comorbidity, and may also have implications for treatment.

Abstract
Investigations of executive dysfunctions among people with obsessive-compulsive personality disorders (OCPD) have yielded inconsistent results. The authors speculate that obsessive-compulsive personality traits (OCPT) from a nonclinical population may be associated with specific executive dysfunctions relative to working memory, attentional set-shifting, and planning. A sample consisting of 79 adults (39 females, 40 males) was divided into high and low scorers on the Personality Diagnostic Questionnaire-4 (PDQ-4; Hyler, 1994). In addition, these participants were interviewed using the SCID-II (First, Spitzer, Gibbon & Williams, 1997) to confirm the presence of symptoms of obsessive-compulsive personality. Participants completed a battery of executive tasks associated with the Cambridge Neuropsychological Test Automated Battery (CANTAB), including Spatial Working Memory, Intradimensional/Extradimensional (ID/ED), Attentional Set-Shifting, and Stockings of Cambridge. Also, self-report measures of executive functions as well as of anxiety and depressive symptoms were administered. The analysis of covariance revealed significant differences between participants with OCPT and controls on the Spatial Working Memory tasks, ID/ED tasks, Stockings of Cambridge, and the Dysexecutive Questionnaire (DEX). Nevertheless, there were no significant differences in the number of problems solved in minimum movements. These results suggest that executive dysfunctions are present in people with prominent OCPT and that there is a high convergence between clinical and ecological measures of executive functions in people with obsessive personality traits.

Abstract
OBJECTIVE We aim to determine how increasing the specificity of binge eating criteria affects the prevalence of self-reported binge eating among presurgical bariatric patients. METHOD 197 women ages 20 to 65 being assessed for bariatric surgery with a BMI greater than 30kg/m(2) were interviewed and completed the Eating and Exercise Examination. RESULTS The prevalence of self-reported binge eating was 55% (n=109). The addition of the criterion 'more than a little loss of control/distress' reduced the rate to 23% (n=45), a minimum of six servings of food reduced the rate to 34% (n=67). The addition of a minimum frequency of twice per week for six months (DSM-VI) reduced the rate to 22% (n=43), or once per week for three months (DSM-5) reduced the rate to 53% (n=104). DISCUSSION More precise definitions and diagnostic criteria for binge eating may result in more consistent reports of prevalence levels of BED.

Abstract
OBJECTIVE The Beck Depression Inventory (BDI) is often used to assess depression symptoms, but its factor structure and its clinical utility have not been evaluated in patients with binge eating disorder (BED) and obesity. METHODS A total of 882 treatment-seeking obese patients with BED were administered structured interviews (Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders) and completed self-report questionnaires. RESULTS Exploratory and confirmatory factor analyses supported a brief 16-item BDI version with a three-factor structure (affective, attitudinal and somatic). Both 21- and 16-item versions showed excellent internal consistency (both α=0.89) and had significant correlation patterns with different aspects of eating disorder psychopathology; three factors showed significant but variable associations with eating disorder psychopathology. Area under the curves (AUC) for both BDI versions were significant in predicting major depressive disorder (MDD; AUC=0.773 [16-item], 73.5% sensitivity/70.2% specificity, AUC=0.769 [21-item], 79.5% sensitivity/64.1% specificity) and mood disorders (AUC=0.763 [16-item], 67.1% sensitivity/71.5% specificity, AUC=0.769 [21-item], 84.2% sensitivity/55.7% specificity). The 21-item BDI (cutoff score ≥16) showed higher negative predictive values (94.0% vs. 93.0% [MDD]; 92.4% vs. 88.3% [mood disorders]) than the brief 16-item BDI (cutoff score ≥13). CONCLUSIONS Both BDI versions demonstrated moderate performance as a screening instrument for MDD/mood disorders in obese patients with BED. Advantages and disadvantages for both versions are discussed. A three-factor structure has potential to inform the conceptualization of depression features.

Abstract
Evidence suggests that both obesity and binge eating disorder (BED) may be associated with deficits in cognitive functioning. The purpose of this study was to examine whether a lifetime history of BED would be associated with changes in several domains of cognitive functioning (attention, executive function, language, and memory) following bariatric surgery. Participants were 68 bariatric surgery patients who completed a computerized battery of cognitive tests within 30 days prior to undergoing surgery and again at a 12-Month postoperative follow-up. Results revealed that on the whole, participants displayed improvements from baseline to follow-up in attention, executive function, and memory, even after controlling for diagnostic history of depression; no changes were observed for language. However, individuals with and without a history of BED did not differ in changes in body mass index or in the degree of improvement in cognitive functioning from baseline to follow-up. Such results suggest that a history of BED does not influence changes in cognitive functioning following bariatric surgery. Future research will be needed to further clarify the role of BED in predicting cognitive function over time.

Abstract
OBJECTIVE To compare the prevalence and correlates of psychiatric co-morbidity across a large sample of college women without an eating disorder, those at high risk for an eating disorder and women diagnosed using DSM-5 criteria for an eating disorder. PARTICIPANTS 549 college women aged 18-25. METHODS Data from the Eating Disorder Examination, the Structured Clinical Interview for DSM-IV Axis I disorders and self-report questionnaires were analyzed using logistic regression for categorical data and ANCOVA for continuous measures. RESULTS Eating disordered symptomatology was strongly associated with anxiety disorders, mood disorders and insomnia. These co-morbidities (type and severity) tend to increase with eating disorder symptom severity. CONCLUSIONS Prevention and treatment programs for eating disorders need to address the high levels of mood, anxiety and sleep problems in this population. The findings on insomnia are novel and suggest that sleep disturbance may play an integral role in eating-related difficulties.

Abstract
OBJECTIVE Studies of age of first binge have been conducted in clinical samples of patients with bulimia nervosa (BN) and binge eating disorder (BED), but few studies have examined age of first binge using nationally representative samples. METHOD We examined age of first binge and its clinical correlates using data generated from the National Women's Study (n = 3,006). Participants who endorsed ever binge eating (n = 707) were divided into two groups: (1) child-adolescent onset (CO)--age of first binge <18 years, and (2) adult onset (AO)--age of first binge ≥18 years. We hypothesized that CO binge eating would be associated with greater (1) likelihood of developing BN/BED, (2) severity of BN/BED, (3) history of trauma and PTSD, and (4) history of psychiatric comorbidity, such as major depression and substance use. RESULTS Of those who ever endorsed binge eating, 212 reported CO (30%) and 495 (70%) reported AO. Although AO binge eating was more common, CO binge eating was associated with higher rates of lifetime BN, greater severity of bulimic symptoms, earlier age of first dieting; earlier age at highest weight, greater likelihood of ED treatment, and higher rates of molestation, physical assault, any direct victimization, lifetime PTSD, and substance abuse. CONCLUSIONS AO binge eating is more than twice as common as CO binge eating in women, but CO binge eating is associated with higher rates of lifetime BN, greater severity of BN, and higher rates of victimization, PTSD, and substance abuse.

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.

Changing the course of comorbid eating disorders and depression: what is the role of public health interventions in targeting shared risk factors? J Eat Disord 2014; 2:15.

Abstract
Public health has a productive history of improving global health due to its focus on reaching large populations using effective and scalable interventions. Yet, the marriage between evidence-based science and the implementation of community/public health interventions within mental illness remains underdeveloped. Research suggests that major depression is the most commonly cited comorbidity for eating disorders (EDs). Thus, identification of public health strategies that jointly impact depression and EDs, including shared risk factors, has the potential to significantly impact mental health suffering. The primary aim of this paper is to examine and discuss such public health approaches as well as explore cues taken from public health efforts to inform future directions in research and clinical practice. As a comprehensive review of all public health initiatives that address EDs and depression is beyond the scope of this paper, this paper reviews a series of programs/approaches that either are of large scale and/or have received empirical support. In particular, public health related interventions that aim to reduce variable risk factors associated with EDs and depression, as well as interventions that aim to reduce continuous measures of ED and depression symptoms are reviewed. To date, despite significant progress in modifying risk factors for EDs and depression, the field still lacks a public health study that has been appropriately designed and/or adequately powered to assess true ED/depression prevention effects. Further, although several programs show promise, many widely disseminated approaches lack empirical support, raising concerns about the potential for waste of limited resources. In summary, although the combination of prevention and public health based approaches appear to have merit when trying to move the needle on risk factors and symptoms associated with EDs and/or depression, further research is needed to investigate the reach and effectiveness of large scale dissemination efforts of such endeavors.

Abstract
Obesity is one of the leading causes of preventable diseases and disability worldwide, and depression is among the leading causes of burden of disease. Both disorders are increasingly prevalent and comorbid. This comorbidity compounds associated health. While there is consistent evidence of a bidirectional obesity depression relationship, little is known about the biopsychosocial variables associated with this relationship. A systematic review was undertaken to identify variables associated with the relationship between obesity (Body mass index > 30 kg m(-2) ) and depression. Forty-six studies were identified. Obesity, educational attainment, body image, binge eating, physical health, psychological characteristics and interpersonal effectiveness were consistently associated with the relationship between obesity and depression. The current review identified potential biopsychosocial variables associated with the relationship between obesity and depression. This knowledge can inform future research examining moderators, mediators and mechanisms of the relationship between obesity and depression. Improved understanding of this relationship will inform identification, prevention and intervention efforts.

Abstract
OBJECTIVE The prognosis for eating disorders (ED) is unsatisfactory, and the literature about outcome indicators is controversial. The present study evaluates the roles of self-esteem, personality disorders (PD), and dissociation as outcome predictors. METHOD Fifty-seven ED outpatients were recruited from a population beginning a Cognitive Behavioral Therapy-Enhanced (CBT-E) treatment. All patients received the Structured Clinical Interview for DSM-IV Axis I (SCID-I), the Structured Clinical Interview for DSM-IV Axis II (SCID-II), and completed the Eating Disorder Examination Questionnaire (EDE-Q), the Dissociation Questionnaire (DIS-Q), and the Rosenberg Self-Esteem Scale (RSES). One month after the end of treatment, recovery was evaluated as meeting the DSM-IV criteria for EDs. RESULTS A small group of patients recovered (42.2%). Low self-esteem and dissociation results correlated with a negative outcome. DISCUSSION Dissociation may be an important moderator of psychotherapy and treatment success, as already suggested by previous studies on non-eating-related disorders.

Abstract
OBJECTIVE To examine DSM-IV lifetime/current psychiatric disorder co-morbidity and correlates in ethnically-diverse obese patients with binge eating disorder (BED) seeking treatment for obesity and binge eating in primary care. METHOD A consecutive series of 142 participants (43% Caucasian, 37% African-American, 13% Hispanic-American, and 7% "other" ethnicity) were evaluated with semi-structured interviews. RESULTS 67% of BED patients had at least one additional lifetime psychiatric disorder, with mood (49%), anxiety (41%), and substance-use (22%) disorders most common. In terms of current co-morbidity, 37% had at least one other psychiatric disorder, with anxiety (27%) and mood (17%) most common. Few gender differences were observed but psychiatric co-morbidity rates differed across ethnic/racial groups with larger differences for current diagnoses. African-American and Hispanic groups were more than twice as likely as the Caucasian group to have additional current psychiatric disorders, mood disorders, and anxiety disorders. Psychiatric co-morbidity was associated with greater eating-disorder psychopathology and poorer functioning, but not with binge-eating or BMI. CONCLUSION Our study presents new findings suggesting that among obese BED patients in primary care, ethnic/racial minority groups are more likely than Caucasian groups to present with psychiatric co-morbidity. Within BED, psychiatric co-morbidity shows few gender differences but is associated with greater eating-disorder psychopathology and poorer functioning.

Abstract
OBJECTIVE To explore the extent to which binge eating in the absence of compensatory behaviors (BE) is associated with psychiatric and medical symptoms in men and women and to control for the independent effects of BMI. RESEARCH METHODS AND PROCEDURES A series of regression models was applied to questionnaire data on 8045 twins, 18 to 31 years old, from a population-based Norwegian registry. RESULTS BE was significantly associated with elevated obesity, overweight, symptoms of eating disorders, symptoms of anxiety and depression, panic attacks, depressive episodes, and reduced life satisfaction in both men and women. In women, BE was independently associated with insomnia and early menarche. In men, BE was independently associated with specific phobia, daily smoking, alcohol use, use of pain medication, impairment due to mental health, neck-shoulder, lower back, and chronic muscular pain, and impairment due to physical health. Both men and women with BE reported higher rates of psychiatric treatment. DISCUSSION Our results indicate that there is substantial comorbidity between BE and psychiatric symptoms independently of BMI for both men and women. Medical symptoms co-occur less frequently than previously reported from treatment-seeking populations in women. Across all domains, the array of symptoms exhibited by men with BE was broader than that observed in women with BE. This observation suggests the importance of considering gender differences in future studies of psychiatric and medical morbidity, binge eating, and obesity.

Abstract
Binge eating disorder (BED) is the most prevalent eating disorder in adults, and individuals with BED report greater general and specific psychopathology than non-eating disordered individuals. The current paper reviews research on psychological treatments for BED, including the rationale and empirical support for cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPT), dialectical behavior therapy (DBT), behavioral weight loss (BWL), and other treatments warranting further study. Research supports the effectiveness of CBT and IPT for the treatment of BED, particularly for those with higher eating disorder and general psychopathology. Guided self-help CBT has shown efficacy for BED without additional pathology. DBT has shown some promise as a treatment for BED, but requires further study to determine its long-term efficacy. Predictors and moderators of treatment response, such as weight and shape concerns, are highlighted and a stepped-care model proposed. Future directions include expanding the adoption of efficacious treatments in clinical practice, testing adapted treatments in diverse samples (e.g., minorities and youth), improving treatment outcomes for nonresponders, and developing efficient and cost-effective stepped-care models.

Abstract
OBJECTIVE Quality of life (QoL) is impaired in obesity, but the roles of eating behavior and psychological distress need to be more documented. METHODS One hundred thirty consecutive obese patients seeking medical care filled out questionnaires evaluating QoL, the presence of an eating disorder (ED), levels of anxiety and depression, and perception of body image. RESULTS Global QoL was poor in 16.4% and intermediate in 61.8% of the patients. EDs were present in 58% of patients who were more (P = 0.05) overweight; 24.2% of patients had binging. EDs impaired significantly the global and specific dimensions of QoL; binging impaired physical and sexual QoLs (both P < 0.02). Anxiety and depression were found in 73.6% and 50.4% of patients, respectively; depression was more frequent in women (P = 0.007) and in patients with EDs. Anxiety and/or depression impaired global (P < 0.001) and specific dimensions of QoL. Body shape concern was marked in 86.4% of women and associated with poor global (P < 0.001) and specific QoL, and with anxiety and depression. CONCLUSION The impairment of QoL in obese patients is increased by the presence of an ED, anxiety, and/or depression and marked body shape concern. These psychological factors should be assessed more carefully and taken into account in global strategies aiming to improve the well-being of obese patients.

Abstract
Eating disorders are a significant source of psychiatric morbidity in young women and demonstrate high comorbidity with mood, anxiety, and substance use disorders. Thus, clinicians may encounter eating disorders in the context of treating other conditions. This review summarizes the efficacy of current and emerging treatments for anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Treatment trials were identified using electronic and manual searches and by reviewing abstracts from conference proceedings. Family based therapy has demonstrated superiority for adolescents with AN but no treatment has established superiority for adults. For BN, both 60 mg fluoxetine and cognitive behavioral therapy (CBT) have well-established efficacy. For BED, selective serotonin reuptake inhibitors, CBT, and interpersonal psychotherapy have demonstrated efficacy. Emerging directions for AN include investigation of the antipsychotic olanzapine and several novel psychosocial treatments. Future directions for BN and BED include increasing CBT disseminability, targeting affect regulation, and individualized stepped-care approaches.

Abstract
The aim of this article is to discuss critical issues in treating males with eating disorders, and to present assessment and treatment outcome data for 111 males who received residential treatment for moderate to severe eating disorders. Males with eating disorders are often not included in eating disorder research as the population of individuals with eating disorders has historically been predominantly female. Whether this is due to actual lower prevalence of this disorder among males or to fewer males seeking treatment is not clear. In any case, there is limited empirical research on the particular treatment issues of males, and in treatment environments males are frequently in the minority. We have found that an all-male treatment environment is helpful in allowing males to benefit from treatment with less stigma. Data are presented which characterize psychiatric co-morbidity, excessive exercise, body image, sexuality, and spirituality in males. Treatment outcomes for males in this environment are positive.

Abstract
Both binge eating disorder (BED) and pathological gambling (PG) are characterized by impairments in impulse control. Subsyndromal levels of PG have been associated with measures of adverse health. The nature and significance of PG features in individuals with BED is unknown. Ninety-four patients with BED (28 men and 66 women) were classified by gambling group based on inclusionary criteria for Diagnostic and Statistical Manual-IV (DSM-IV) PG and compared on a range of behavioral, psychological and eating disorder (ED) psychopathology variables. One individual (1.1% of the sample) met criteria for PG, although 18.7% of patients with BED displayed one or more DSM-IV criteria for PG, hereafter referred to as problem gambling features. Men were more likely than women to have problem gambling features. BED patients with problem gambling features were distinguished by lower self-esteem and greater substance problem use. After controlling for gender, findings of reduced self-esteem and increased substance problem use among patients with problem gambling features remained significant. In patients with BED, problem gambling features are associated with a number of heightened clinical problems.

Abstract
This prospective study investigated personality traits as predictors of the outcome in a 52-week weight-loss program for obesity. Personality traits were rated with the Inventory of Interpersonal Problems (IIP) in 54 consecutive obese outpatients when entering a multimodal weight-reduction program. The value of these variables to predict success was assessed after 12, 26, and 52 weeks of treatment. A stepwise linear regression analysis for all follow-ups was calculated to examine the impact of each IIP item subscale on weight reduction. The IIP item subscale "intrusive or needy" significantly correlated with weight reduction observed at every follow-up examination and accounts for 13.6% to 29.8% of the variance (p values < .05). Obese patients describing themselves as excessively friendly, outgoing, and sociable improved more from a weight-loss program than those with lower instances of these traits. Accordingly, personality traits deserve more attention at initial assessment and while planning treatment of obese patients.

Abstract
OBJECTIVE To explore similarities and differences in clinical and personality variables across three groups: binge eating disorder (BED), bulimia nervosa-purging type (BN-P), and bulimia nervosa-non purging type (BN-NP). METHOD The participants were 102 female eating disorders patients (34 BED, 34 BN-P, and 34 BN-NP) consecutively admitted to the eating disorders unit, at the University Hospital of Bellvitge, and diagnosed according to DSM-IV criteria. RESULTS BED patients were older, and more likely to have personal and family history of obesity. A gradient in psychopathological scores emerged with BN-P patients having higher pathological scores on the SCL-90-R, followed by BN-NP and BED patients. No statistically significant differences were observed in personality traits. DISCUSSION Our data supported that eating disorders (namely BED, BN-NP, and BN-P) followed a linear trend in general psychopathology. Whereas personality may represent a shared vulnerability factor, differences in clinical severity suggest there to be a continuum with BN-P being the most severe and BED being the least severe.

Abstract
OBJECTIVE The aim of this study was to examine how alcohol intake changes during and after transdiagnostic cognitive behaviour therapy for eating disorders (CBT-E). Additionally, the paper considers the relationship between alcohol consumption, eating disorder diagnosis and current major depressive episode at the time of first assessment. METHOD One hundred and forty nine outpatients with an eating disorder (body mass index over 17.5) were divided into high or low alcohol intake groups (HIG and LIG) according to their intake at pre-treatment assessment. Their alcohol intake and eating disorder psychopathology were examined over the course of treatment and follow-up. RESULTS There was no difference between the groups on response of the eating disorder to treatment. The HIG significantly reduced their alcohol intake following treatment whilst the intake of the LIG remained stable over the course of treatment and follow-up. There were no group differences in major depression and overall severity of eating disorder at baseline. CONCLUSIONS The response to CBT-E was not influenced by baseline level of alcohol use. The mean alcohol intake of the heavy drinking subjects decreased without being specifically addressed by the treatment.

Abstract
OBJECTIVE To examine correlates of childhood maltreatment in women with binge-eating disorder (BED). METHOD Semistructured interviews evaluated 137 women with BED for psychiatric disorders and eating psychopathology, and self-reported childhood maltreatment was assessed. RESULTS Emotional abuse was reported by 52% of participants, physical abuse by 28%, sexual abuse by 31%, emotional neglect by 66%, and physical neglect by 48%. Maltreatment categories were not associated with most lifetime psychiatric diagnoses, although specific associations were observed for dysthymic disorder, posttraumatic stress disorder, and alcohol use disorders. Few associations were noted with eating pathology, but most forms of childhood maltreatment were negatively associated with self-esteem. DISCUSSION Women with BED report rates of childhood maltreatment comparable to those for clinical groups, and much higher than community samples. Although prevalent in women with BED, childhood maltreatment is not generally associated with variability in eating pathology or with psychiatric comorbidity, but is associated with lower self-esteem.
