Calorie estimation accuracy and menu labeling perceptions among individuals with and without binge eating and/or purging disorders. Eat Weight Disord 2013; 18:255-61. [PMID: 23760909 DOI: 10.1007/s40519-013-0035-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2011] [Accepted: 10/24/2012] [Indexed: 10/26/2022] Open
Abstract
Menu labeling is a public health policy that requires chain restaurants in the USA to post kilocalorie information on their menus to help consumers make informed choices. However, there is concern that such a policy might promote disordered eating. This web-based study compared individuals with self-reported binge eating disorder (N = 52), bulimia nervosa (N = 25), and purging disorder (N = 17) and those without eating disorders (No ED) (N = 277) on restaurant calorie information knowledge and perceptions of menu labeling legislation. On average, people answered 1.46 ± 1.08 questions correctly (out of 6) (25%) on a calorie information quiz and 92% of the sample was in favor of menu labeling. The findings did not differ based on eating disorder, dieting, or weight status, or race/ethnicity. The results indicated that people have difficulty estimating the calories in restaurant meals and individuals with and without eating disorders are largely in favor of menu labeling laws.

Abstract
OBJECTIVE This study aimed to compare diet soda drinkers, regular soda drinkers, and individuals who do not regularly consume soda on clinically significant eating disorder psychopathology, including binge eating, overeating, and purging. METHOD Participants (n=2077) were adult community volunteers who completed an online survey that included the Eating Disorder Examination Questionnaire and questions regarding binge eating behaviors, purging, current weight status, and the type and frequency of soda beverages consumed. RESULTS Diet soda drinkers (34%, n=706) reported significantly higher levels of eating, shape, and weight concerns than regular soda drinkers (22%, n=465), who in turn reported higher levels on these variables than non-soda drinkers (44%, n=906). Diet soda drinkers were more likely to report binge eating and purging than regular soda drinkers, who were more likely to report these behaviors than non-soda drinkers. Consumption of any soda was positively associated with higher BMI, though individuals who consumed regular soda reported significantly higher BMI than diet soda drinkers, who in turn reported higher weight than those who do not consume soda regularly. CONCLUSIONS Individuals who consume soda regularly reported higher BMI and more eating psychopathology than those who do not consume soda. These findings extend previous research demonstrating positive associations between soda consumption and weight.

Abstract
BACKGROUND The Eating Disorder Examination-Questionnaire (EDE-Q), a widely used self-report instrument, is often used for measuring change in eating disorder symptoms over the course of treatment. However, limited data exist about test-retest reliability, particularly for men. The current study evaluated EDE-Q 7-day test-retest reliability in male (n = 47) and female (n = 44) undergraduate students together and separately by gender. RESULTS Internal consistency was consistently higher for women and at Time 2, but remained acceptable for both men and women at both time points. Cronbach's α ranged from .75 (Restraint at Time 1) to .93 (Shape Concern at Time 2) for women and from .73 (Eating Concern at Time 2) to .89 (Shape Concern at Time 2) for men. With the exception of some of the eating disorder behaviors, test re-test reliability was fairly strong for both men and women. Shape Concern and the global EDE-Q score were highest for both men and women (Spearman's rho > 0.89 with the exception of Shape Concern for women for which Spearman's rho = .86). Test re-test reliability was lower for the eating disorder behavior measures, particularly for men, for whom Kendall's tau-b for frequency and phi for occurrence was less than 0.70 for all but objective bulimic episodes. CONCLUSIONS Results were consistent with past research for women, indicating strong test re-test reliability in attitudinal features of eating disorders, but lower test re-test reliability in behavioral features. Internal consistency and test re-test reliability was good for the attitudinal features of eating disorder in men, but tended to be lower for men compared to women. The EDE-Q appears to be a reliable instrument for assessing eating disorder attitudes in both male and female undergraduate students, but is less reliable for assessing ED behaviors, particularly in men.

Abstract
BACKGROUND Body image disturbance is a core feature of anorexia nervosa (AN). Attitudinal and cognitive biases as well as fundamental perceptual differences have been hypothesized to play a role in this disturbance. METHOD This study investigated body image dissatisfaction and distortion, haptic perception and perfectionism in 30 patients with AN and 31 age-matched healthy controls. Participants completed perceptual tasks and self-report measures. RESULTS As predicted, participants with AN scored significantly higher on body dissatisfaction, perfectionism measures and had greater body distortion (as assessed by a body size estimation task). Cognitive-affective factors and perfectionism were highly correlated with body image distortion in AN. No significant differences were found between groups on the generic perception task. CONCLUSIONS Findings did not confirm the hypothesis of fundamental perceptual inefficiencies in body image disturbance in individuals with AN. Despite renewed interest in fundamental perceptual factors implicated in body image disturbance, these findings suggest that it continues to be important to focus treatment on cognitive affective biases versus fundamental perceptual inefficiencies.

Abstract
OBJECTIVE The current study explored the clinical meaningfulness of distinguishing subjective (SBE) from objective binge eating (OBE) among individuals with threshold/subthreshold bulimia nervosa (BN). We examined relations between OBEs and SBEs and eating disorder symptoms, negative affect, and personality dimensions using both a group comparison and a continuous approach. METHOD Participants were 204 adult females meeting criteria for threshold/subthreshold BN who completed questionnaires related to disordered eating, affect, and personality. RESULTS Group comparisons indicated that SBE and OBE groups did not significantly differ on eating disorder pathology or negative affect, but did differ on two personality dimensions (cognitive distortion and attentional impulsivity). Using the continuous approach, we found that frequencies of SBEs (not OBEs) accounted for unique variance in weight/shape concern, diuretic use frequency, depressive symptoms, anxiety, social avoidance, insecure attachment, and cognitive distortion. DISCUSSION SBEs in the context of BN may indicate broader areas of psychopathology.

Modeling the effects of positive and negative mood on the ability to resist eating in obese and non-obese individuals. Eat Behav 2013; 14:40-6.

Abstract
This pilot study adapted a well-established drug self-administration paradigm to examine the effects of mood induction on the ability to resist high-calorie foods and subsequent food consumption differently in 15 obese individuals (40.0% women, BMI: 35.1±3.70) and 15 non-obese individuals (46.7% women, BMI: 23.0±1.96). Participants completed two laboratory sessions (positive vs. negative mood conditions) consisting of 3-hour food deprivation, followed by mood induction, and a 3-hour ad-lib eating period, where they were asked to choose between favorite high-calorie snacks and monetary reinforcement. Obese individuals were less able to resist eating and increased high-calorie food consumption during the positive mood condition than the negative condition. Non-obese individuals were less able to resist eating during the negative mood condition than the positive condition, but their total consumption was not affected by the mood conditions. In obese individuals, food craving was associated with less ability to resist eating and greater calorie consumption during the negative mood condition. This is the first study to experimentally demonstrate that mood state may increase vulnerability to food consumption by reducing the ability to resist eating. The ability to resist eating may be a novel dimension of eating behaviors that has a significant contribution to understanding mood-eating relationships.

Abstract
The Night Eating Syndrome (NES) is a recently described disordered eating style whose status in current diagnostic systems needs to be further clarified. The aim of this study was to increase knowledge about the clinical features of NES in a sample of 1514 young adults aged 18-26 years from the general population who participated in an anonymous Internet survey. We first examined characteristics of NES and tried to delineate it from healthy controls as well as from other eating disorders in terms of socio-demography, eating disorder pathology and general psychopathology. Second, we attempted to further clarify the clinical utility of the NES by assessing the degree of distress as well as impairment. Twenty (1.3%) participants with NES were identified and there was only modest overlap between NES and both Binge Eating Disorder (BED) and Bulimia nervosa (BN) according to questionnaire-based DSM-IV criteria. Compared to healthy controls, NES individuals reported more pronounced eating disorder pathology as well as general psychopathology (depressive symptoms, chronic social stress). NES seems to be associated with considerable distress and impairment. Implications for the validity and classification of NES are discussed.

Abstract
The first aim of this study was to provide norms for the Eating Disorder Examination Questionnaire (EDE-Q) in a diverse and large clinical sample of individuals with an eating disorder (ED), and a general population sample without an ED. Norms for individuals with obesity without an ED were also provided, as a more relevant comparison group for individuals with binge eating disorder. The second aim was to investigate the discriminative validity of the EDE-Q. A sample of females with an ED (N=935), women from the general population without an ED (N=235), and obese females without an ED (N=321) completed the EDE-Q. Explorative factor analyses did not support the theorized four subscales of the EDE-Q. Norms for EDE-Q global scores were provided for each of the three samples. Within the ED sample, norms were provided separately for patients with different ED diagnoses. Receiver operating characteristic analyses showed the EDE-Q global score to be highly accurate in discriminating individuals with an ED from those without, and moderately accurate in discriminating individuals with binge eating disorder from those with obesity. The presented norms contribute to a more accurate interpretation of EDE-Q scores, providing an index of the severity level of ED psychopathology. Furthermore, these norms can be used to assess clinical significant change during treatment. In addition, this study demonstrates that the EDE-Q, when using its global score, is a valid instrument to assess levels of ED psychopathology.

Abstract
BACKGROUND Binge eating disorder (BED) is a complex and multifaceted eating disorder, and the literature indicates that BED patients show greater difficulty in identifying and making sense of emotional states, and that they have limited access to emotion regulation strategies. Findings show many links between mindfulness and emotional regulation, however there has been no previous research on mindfulness traits in BED patients. METHOD One hundred fifty BED patients (N=150: women=98, men=52; age 49.3±4.1) were matched for gender, age, marital status and educational level with 150 non-bingeing obese and 150 normal-weight subjects. All were assessed with the Five Facet Mindfulness Questionnaire (FFMQ), Binge Eating Scale (BES), Objective bulimic episodes (EDE-OBEs) and Body Uneasiness Test (BUT). For all the participants past or current meditation experience was an exclusion criteria. RESULTS Findings showed that Mindfulness-global, Non reactivity to experience, Acting with awareness, Describing with words and Observation of experience scores were significantly lower in BED than control groups (p<0.05). However, on the mindfulness measures, the obese control group did not differ from the normal weight control group. Moreover, correlations showed that mindfulness was more widely negatively correlated with the BED's OBEs, BES and BUT-GSI scores. Meanwhile, binge eating behaviours, frequency and severity (OBEs and BES) were more negatively correlated with action (Nonreactivity- to-experience and Acting-with-awareness scores). Body Uneasiness was more negatively correlated with mental processes (Describing-with-words and Observation-ofexperience) and mindfulness features. CONCLUSION Implications on understanding of the mechanisms underlying the development and maintenance of problematic eating in BED were considered. Moreover, clinical considerations on treatment targets of mindfulnessbased eating awareness training were discussed.

Abstract
OBJECTIVE The longer term efficacy of medication treatments for binge-eating disorder (BED) remains unknown. This study examined the longer term effects of fluoxetine and cognitive behavioral therapy (CBT) either with fluoxetine (CBT + fluoxetine) or with placebo (CBT + placebo) for BED through 12-month follow-up after completing treatments. METHOD 81 overweight patients with BED within a randomized double-blind placebo-controlled acute treatment trial allocated to fluoxetine-only, CBT + fluoxetine, and CBT + placebo were assessed before treatment, during treatment, posttreatment, and 6 and 12 months after completing treatments. Outcome variables comprised remission from binge eating (0 binge-eating episodes for 28 days) and continuous measures of binge-eating frequency, eating disorder psychopathology, depression, and weight. RESULTS Intent-to-treat remission rates (missing data coded as nonremission) differed significantly across treatments at posttreatment and at 6- and 12-month follow-ups. At 12-month follow-up remission rates were 3.7% for fluoxetine-only, 26.9% for CBT + fluoxetine, and 35.7% for CBT + placebo. Mixed-effects models of all available continuous data (without imputation) at posttreatment and at 6- and 12-month follow-ups (controlling for baseline scores) revealed the treatments differed on all clinical outcome variables, except for weight, across time. CBT + fluoxetine and CBT + placebo did not differ and both were significantly superior to fluoxetine-only on the majority of clinical outcomes. CONCLUSIONS This represents the first report from any randomized placebo-controlled trial for BED that has reported follow-up data after completing a course of medication-only treatment. CBT + placebo was superior to fluoxetine-only, and adding fluoxetine to CBT did not enhance findings compared to adding placebo to CBT. The findings document the longer term effectiveness of CBT, but not fluoxetine, through 12 months after treatment completion.

Abstract
Little research has explored how eating disorders (ED) may be involved in the increased risk for metabolic syndrome in adults on antipsychotic medication. This pilot study compared participants on antipsychotic medication with obese and ED samples with respect to demographic and psychosocial factors. Participants (antipsychotic medication n = 12; obese n = 12; ED n = 12), were adults presenting to an outpatient psychiatry department (83.3% women; M age = 45.75 ± 11.5). Analysis of variance, analysis of covariance and chi-square tests were used to compare the samples. Participants on antipsychotic medications had a significantly lower mean body mass index than the obese (p < .001) and ED (p < .05) samples, as well as significantly lower Restraint Total scores (p < .05) and subjective binge episode frequency (p < .05) than the ED sample. The lack of significant differences that occurred between the antipsychotic medication sample and two eating disorder samples significantly different from one another indicates that this population may have unique symptomology and treatment needs.

Abstract
OBJECTIVE This study assessed the accuracy of self-reported weight, height, and body mass index in obese patients with binge-eating disorder (DSM-IV-TR criteria) presenting at primary care clinics and tested whether the degree of inaccuracy was associated with demographic factors or eating disorder and depressive features. METHOD Sixty-six participants were interviewed using the Eating Disorder Examination interview, completed the Eating Disorder Examination Questionnaire and the Beck Depression Inventory, and had their height and weight measured between November 2007 and May 2009. RESULTS Self-reported and measured weight did not differ significantly, but participants significantly overestimated their height (P < .01), and this discrepancy resulted in a significantly lower self-reported than measured body mass index (P < .05). Discrepancy scores did not differ by eating disorder or depressive symptoms, sex, or ethnicity, although increasing age was associated with overestimation of height and underestimation of body mass index. CONCLUSIONS The findings suggest that obese patients with binge-eating disorder in primary care settings are reasonably accurate reporters of weight and height and that the degree of inaccuracy does not appear to be systematically related to eating disorder psychopathology or depressive features.

Abstract
OBJECTIVE This study examined interrelationships between cigarette smoking for weight control and eating disorder symptoms in a community sample of adult female smokers. METHOD Participants were 107 female smokers who completed a battery of questionnaires, including the Eating Disorder Examination-Questionnaire (EDE-Q). Key items measured weight-control smoking, including smoking to prevent overeating, smoking to undo the effects of overeating, and smoking to feel less hungry. Smokers who endorsed smoking in an attempt to control weight were compared with those who denied such behaviors on EDE-Q scores and frequency of binge eating and purging. RESULTS A substantial proportion of participants reported weight-control smoking. Participants who endorsed weight-control smoking reported elevations on eating disorder symptoms as measured by the EDE-Q. Compensatory smoking was related to the frequency of binge eating. DISCUSSION The findings have implications for clinicians working with eating disorder patients; for some individuals, cigarette smoking may be used as an attempt to compensate for overeating.

Abstract
OBJECTIVE The purpose of this study was to systematically review the reliability of scores on the Eating Disorder Examination (EDE) and the Eating Disorder Examination-Questionnaire (EDE-Q) and to examine the validity of their use as measures of eating disorder symptoms. METHOD Articles describing the psychometric properties of the EDE and EDE-Q were identified in a systematic search of major computer databases and a review of reference lists. Articles were selected based on a priori inclusion and exclusion criteria. RESULTS Fifteen studies were identified that examined the psychometrics of the EDE, whereas 10 studies were found that examined the psychometrics of the EDE-Q. DISCUSSION Both instruments demonstrated reliability of scores. There is evidence that scores on the EDE and EDE-Q correlate with scores on measures of similar constructs and support for using the instruments to distinguish between cases and non-cases. Additional research is needed to broaden the generalizability of the findings.

Abstract
Identifying measures that reliably and validly assess clinical impairment has important implications for eating disorder (ED) diagnosis and treatment. The current study examined the psychometric properties of the Clinical Impairment Assessment (CIA) in women at high risk for ED onset. Participants were 543 women (20.6 ± 2.0 years) who were classified into one of three ED categories: clinical ED, high risk for ED onset, and low risk control. Among high risk women, the CIA demonstrated high internal consistency (α = 0.93) and good convergent validity with disordered eating attitudes (rs = 0.27-0.68, ps < 0.001). Examination of the CIA's discriminant validity revealed that CIA global scores were highest among women with a clinical ED (17.7 ± 10.7) followed by high risk women (10.6 ± 8.5) and low risk controls (3.0 ± 3.3), respectively (p < 0.001). High risk women reporting behavioral indices of ED psychopathology (objective and/or subjective binge episodes, purging behaviors, driven exercise, and ED treatment history) had higher CIA global scores than those without such indices (ps < 0.05), suggesting good criterion validity. These data establish the first norms for the CIA in a United States sample. The CIA is psychometrically sound among high risk women, and heightened levels of impairment among these individuals as compared to low risk women verify the relevance of early intervention efforts.

Abstract
OBJECTIVE The aim of the study was to pilot a brief form of interpersonal psychotherapy (IPT) for the treatment of patients with bulimic disorders. METHOD Ten patients with bulimic disorder treated with a new brief version of IPT (IPT-BN10) completed measurements of eating disorders psychopathology (Eating Disorders Examination Questionnaire, Bulimic Investigatory Test Edinburgh) and depression (Beck Depression Inventory). The results were matched with a group of patients treated with conventional IPT and with waiting list control. RESULTS Statistical differences were found between starting and ending of therapy for those patients treated with IPT-BN10. Statistical difference was also found when comparing with waiting list control. DISCUSSION The pilot study suggests that IPT-BN10 may be an effective treatment for patients having bulimic disorders; however, this hypothesis needs to be tested in an experimental way.

Abstract
The aim of this study was to evaluate psychometric properties and clinical correlates of the Weight Bias Internalization Scale (WBIS) in a sample of obese adolescents seeking bariatric surgery. Sixty five adolescents enrolled in a bariatric surgery program at a large, urban medical center completed psychiatric evaluations, self-report questionnaires including the WBIS and other measures of psychopathology and physical assessments. The WBIS had high internal consistency (Cronbach's α = 0.92). As in previous research with adults, the one underlying factor structure was replicated and 10 of the original 11 items were retained. The scale had significant partial correlations with depression (r = 0.19), anxiety (r = 0.465), social, and behavioral problems (r = 0.364), quality of life (r = -0.480), and eating (r = 0.579), shape (r = 0.815), and weight concerns (r = 0.545), controlling for BMI. However, WBIS scores did not predict current or past psychiatric diagnosis or treatment or past suicidal ideation. Overall, the WBIS had excellent psychometric properties in a sample of obese treatment-seeking adolescents and correlated significantly with levels of psychopathology. These findings suggest that the WBIS could be a useful tool for healthcare providers to assess internalized weight bias among treatment-seeking obese youth. Assessment of internalized weight bias among this clinical population has the potential to identify adolescents who might benefit from information on coping with weight stigma, which in turn may augment weight loss efforts.

Abstract
OBJECTIVE This study evaluated duloxetine in the treatment of binge eating disorder (BED) with comorbid current depressive disorders. METHOD In this 12-week, double-blind, placebo-controlled trial, 40 patients with Diagnostic and Statistical Manual of Mental Disorders-IV-TR BED and a comorbid current depressive disorder received duloxetine (N = 20) or placebo (N = 20). The primary outcome measure was weekly binge eating day frequency. RESULTS In the primary analysis, duloxetine (mean 78.7 mg/day) was superior to placebo in reducing weekly frequency of binge eating days (p = .04), binge eating episodes (p = .02), weight (p = .04), and Clinical Global Impression-Severity of Illness ratings for binge eating (p = .02) and depressive disorders (p = .01). Changes in body mass index and measures of eating pathology, depression, and anxiety did not differ between the two groups. DISCUSSION Duloxetine may be effective for reducing binge eating, weight, and global severity of illness in BED with a comorbid current depressive disorder, but this finding needs confirmation in larger, placebo-controlled trials.

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

Abstract
OBJECTIVE The Eating Disorder Examination-Questionnaire (EDE-Q) is a self-report instrument assessing the specific psychopathology and key behaviors of eating disorders. This study sought to determine the prevalence of eating disturbances, and to provide psychometric properties and norms of the EDE-Q, in a representative German population sample. METHODS A total of 2520 individuals (1166 men, 1354 women) were assessed with the EDE-Q. RESULTS Eating disorder psychopathology was higher and most key behaviors were more prevalent in women than in men. Psychopathology declined with age ≥65 in both sexes, and showed a peak at age 55-64 in men. Overall, 5.9% of the women and 1.5% of the men revealed eating disturbances. The prevalence of eating disturbances decreased with age in women and was significantly higher in obese than in normal-weight individuals. Psychometric analyses showed favorable item characteristics. Internal consistencies of EDE-Q composite scores were ≥.80 for women and ≥.70 for men. The factor structure of the EDE-Q was partially reproduced. Sex- and age-specific population norms are reported. DISCUSSION This study provides population norms of the EDE-Q for both sexes and across the age range, demonstrates demographic variations in symptomatology, and reveals satisfactory psychometric properties. Further research is warranted on eating disturbances in older adults.

Abstract
Significant discrepancies have been found between interview- and questionnaire-based assessments of psychopathology; however, these studies have typically compared instruments with unmatched item content. The Eating Disorder Examination (EDE), a structured interview, and the questionnaire version of the EDE (EDE-Q) are considered the preeminent assessments of eating disorder symptoms and provide a unique opportunity to examine the concordance of interview- and questionnaire-based instruments with matched item content. The convergence of EDE and EDE-Q scores has been examined previously; however, past studies have been limited by small sample sizes and have not compared the convergence of scores across diagnostic groups. A meta-analysis of 16 studies was conducted to compare the convergence of EDE and EDE-Q scores across studies and diagnostic groups. With regard to the EDE and EDE-Q subscale scores, the overall correlation coefficient effect sizes ranged from .68 to .76. The overall Cohen's d effect sizes ranged from .31 to .62, with participants consistently scoring higher on the questionnaire. For the items measuring behavior frequency, the overall correlation coefficient effect sizes ranged from .37 to .55 for binge eating and .90 to .92 for compensatory behaviors. The overall Cohen's d effect sizes ranged from -0.16 to -0.22, with participants reporting more binge eating on the interview than in the questionnaire in 70% of the studies. These results suggest the interview and questionnaire assess similar constructs but should not be used interchangeably. Additional research is needed to examine the inconsistencies between binge frequency scores on the 2 instruments.

Abstract
To investigate potential predictors of the severity of binge eating disorder (BED), two subtypes of patients with the disorder, a pure dietary subtype and a dietary-negative affect subtype, were identified. This study investigated the relationships between the two subtypes and impulsivity and reinforcement sensitivity. Ninety-two women meeting threshold and subthreshold criteria for BED diagnosis filled out questionnaires to determine eating disorder severity, impulsivity and reinforcement sensitivity before and after participating in an online guided self-help program for BED. Cluster analyses revealed a pure dietary subtype (N=66, 71.7%) and a dietary-negative affect subtype (N=26, 28.3%). Compared to the pure dietary subtype, the dietary-negative affect subtype reported a higher frequency of objective binge episodes, more severe eating disorders, higher urgency scores (defined as a tendency to act rashly in the context of negative affect), a greater sensitivity to punishment, and a higher dropout rate during treatment. These findings suggest that BED patients in the dietary-negative affect subtype exhibit heightened anxiety and are highly impulsive, especially in contexts of negative affect. For these individuals, psychological interventions for BED should focus on inhibiting automatic responses to negative emotions.

Abstract
OBJECTIVE This study examined the interpersonal model of binge eating (Wilfley et al., Interpersonal Psychotherapy for Group, New York: Basic Books, 2000; Wilfley et al., Arch Gen Psychiatry, 8, 713-721, 2002; Elliott et al., Behav Res Ther, 48, 424-428, 2010) which posits that interpersonal problems lead to negative affect which, in turn, triggers disordered eating. METHOD The model was tested using data from 350 women obtained via an internet assessment method. Analyses examined direct and indirect effects, via depressive/negative affect, of interpersonal problems, including domains of affiliation and dominance on loss of control over eating, binge eating, and eating disorder psychopathology. RESULTS Interpersonal problems showed significant effects on binge eating and eating disorder psychopathology that were statistically mediated by depressive/negative affect. Affiliation showed significant effects on binge eating and eating disorder psychopathology with low affiliation effects statistically mediated by depressive/negative affect and high affiliation effects independent of depressive/negative affect. DISCUSSION These findings support the interpersonal model of binge eating and highlight the importance of examining specific types of interpersonal problems in understanding heterogeneity of individuals with eating disorder psychopathology.

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
Preliminary studies of non-clinical samples suggest that purposely attempting to avoid thoughts of food, referred to as food thought suppression, is related to a number of unwanted eating- and weight-related consequences, particularly in obese individuals. Despite possible implications for the treatment of obesity and eating disorders, little research has examined food thought suppression in obese individuals with binge eating disorder (BED). This study compared food thought suppression in 60 obese patients with BED to an age-, gender-, and body mass index (BMI)-matched group of 59 obese persons who do not binge eat (NBO). In addition, this study examined the associations between food thought suppression and eating disorder psychopathology within the BED and NBO groups and separately by gender. Participants with BED and women endorsed the highest levels of food thought suppression. Food thought suppression was significantly and positively associated with many features of ED psychopathology in NBO women and with eating concerns in men with BED. Among women with BED, higher levels of food thought suppression were associated with higher frequency of binge eating, whereas among men with BED, higher levels of food thought suppression were associated with lower frequency of binge eating. Our findings suggest gender differences in the potential significance of food thought suppression in obese groups with and without co-existing binge eating problems.

Abstract
OBJECTIVE To better understand the eating patterns of persons with eating disorders. METHOD This study investigated typical eating behavior (meal frequency and snacking) and atypical eating behavior among 311 community women with on-line questionnaires. Participants were classified with bulimia nervosa (BN; n =39), binge eating disorder (BED; n = 69), or controls (CON; n = 203). RESULTS In terms of typical eating behaviors, the BN group ate significantly fewer meals, particularly lunches, than the other two groups. Atypical eating, such as nibbling, eating double meals and nocturnal eating, was significantly more common in the eating disorder groups. More frequent breakfast consumption was associated with lower BMI in the BED and CON groups, and more frequent meal consumption was associated with less binge eating in the BED group only. DISCUSSION Our study revealed differences in typical and atypical eating patterns, and associations with weight and eating disorder behaviors among eating disorder and control groups.

Abstract
OBJECTIVE To examine whether changes in different aspects of dietary restraint in obese patients with binge eating disorder (BED) participating in a treatment study predict outcomes. METHOD Fifty obese patients with BED in a randomized controlled study of orlistat administered with cognitive-behavioral therapy, guided-self-help (CBTgsh) completed dietary restraint measures at baseline, during- and post-treatment, and three-month follow-up. RESULTS Change in the restraint scale of the Eating Disorder Examination-Questionnaire did not predict binge abstinence or 5% weight loss. Increased flexible restraint subscale of the Three Factor Eating Questionnaire (TFEQ) during treatment significantly predicted binge abstinence at post-treatment and three-month follow-up and 5% weight loss at post-treatment. Change in the rigid restraint subscale of the TFEQ predicted binge abstinence at post-treatment. DISCUSSION Our findings clarify further pathologic and adaptive aspects of restraint and suggest the importance of enhancing flexible restraint in order to improve both binge eating and weight loss outcomes.

Abstract
Binge eating disorder (BED) is a common and under-treated condition with major health implications. Cognitive behavioural therapy (CBT) self-help manuals have proved to be efficient in BED treatment. Increasing evidence also support the use of new technology to improve treatment access and dissemination. This is the first randomised controlled study to evaluate the efficacy of an Internet guided self-help treatment programme, based on CBT, for adults with threshold and subthreshold BED. Seventy-four women were randomised into two groups. The first group received the six-month online programme with a six-month follow-up. The second group was placed in a six-month waiting list before participating in the six-month intervention. Guidance consisted of a regular e-mail contact with a coach during the whole intervention. Binge eating behaviour, drive for thinness, body dissatisfaction and interoceptive awareness significantly improved after the Internet self-help treatment intervention. The number of objective binge episodes, overall eating disorder symptoms score and perceived hunger also decreased. Improvements were maintained at six-month follow-up. Dropouts exhibited more shape concern and a higher drive for thinness. Overall, a transfer of CBT-based self-help techniques to the Internet was well accepted by patients, and showed positive results for eating disorders psychopathology.

Abstract
OBJECTIVE Research has examined various aspects of the validity of the research criteria for binge eating disorder (BED) but has yet to evaluate the utility of the 5 Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) "indicators for impaired control" specified to help determine loss of control while overeating (i.e., binge eating). We examined the diagnostic efficiency of these indicators proposed as part of the research criteria for BED (eating until uncomfortably full; eating when not hungry; eating more rapidly than usual; eating in secret; and feeling disgust, shame, or depression after the episode). METHOD A total of 916 community volunteers completed a battery of measures including questions about each of the indicators. Participants were categorized into 3 groups: BED (N = 164), bulimia nervosa (BN; N = 83), and non-binge-eating controls (N = 669). Four conditional probabilities (sensitivity, specificity, positive predictive power [PPP], and negative predictive power [NPP]) as well as total predictive value (TPV) and kappa coefficients were calculated for each indicator criterion in separate analyses comparing BED, BN, and combined BED + BN groups relative to controls. RESULTS PPPs and NPPs suggest all of the indicators have predictive value, with eating alone because embarrassed (PPP = .80) and feeling disgusted (NPP = .93) performing as the best inclusion and exclusion criteria, respectively. The best overall indicators for correctly identifying binge eating (based on TPV and kappa) were eating when not hungry and eating alone because embarrassed. CONCLUSIONS All 5 proposed indicators for impaired control for determining binge eating have utility, and the diagnostic efficiency statistics provide guidance for clinicians and the DSM-5 regarding their usefulness for inclusion or exclusion.

Abstract
OBJECTIVE Given the prevalence and health significance of binge eating disorder (BED) it is important to determine if time-efficient self-reports can adequately assess BED and its features in primary care settings. We compared the Eating Disorder Examination-Questionnaire (EDE-Q) and Questionnaire for Eating and Weight Patterns-Revised (QEWP-R), administered to obese patients with BED in primary care setting to the Eating Disorder Examination (EDE) interview. METHOD Sixty-six participants completed the questionnaires and were interviewed. RESULTS The EDE interview was significantly correlated with the EDE-Q (binge eating, four subscales, and global score) and the QEWP-R (binge eating, distress, and body image). The EDE-Q yielded significantly lower estimates of binge eating and significantly higher scores on the EDE subscales. The QEWP-R yielded significantly higher scores on the behavioral indicators and distress about binge eating and body image variables. DISCUSSION These findings suggest that these two self-report measures have potential utility for identifying BED in obese patients in primary care.

Abstract
Binge eating disorder (BED) presents with substantial psychiatric comorbidity. This latent structure analysis sought to delineate boundaries of BED given its comorbidity with affective and anxiety disorders. A population-based sample of 151 women with BED, 102 women with affective or anxiety disorders, and 259 women without psychiatric disorders was assessed with clinical interviews and self-report-questionnaires. Taxometric analyses were conducted using DSM-IV criteria of BED and of affective and anxiety disorders. The results showed a taxonic structure of BED and of affective and anxiety disorders. Both taxa co-occurred at an above-chance level, but also presented independently with twice-as-large probabilities. Within the BED taxon, diagnostic co-occurrence indicated greater general psychopathology, lower social adaptation, and greater premorbid exposure to parental mood and substance disorder, but not greater eating disorder psychopathology. Eating disorder psychopathology discriminated individuals in the BED taxon from individuals in the affective and anxiety disorders taxon. Diagnostic criteria of BED were more indicative of the BED taxon than were criteria of affective and anxiety disorders. The results show that at the latent level, BED was co-occurring with, yet distinct from, affective and anxiety disorders and was not characterized by an underlying affective or anxiety disorder.

Abstract
OBJECTIVE To assess preliminarily the effectiveness of acamprosate in binge eating disorder (BED). METHOD In this 10-week, randomized, placebo-controlled, flexible dose trial, 40 outpatients with BED received acamprosate (N = 20) or placebo (N = 20). The primary outcome measure was binge eating episode frequency. RESULTS While acamprosate was not associated with a significantly greater rate of reduction in binge eating episode frequency or any other measure in the primary longitudinal analysis, in the endpoint analysis it was associated with statistically significant improvements in binge day frequency and measures of obsessive-compulsiveness of binge eating, food craving, and quality of life. Among completers, weight and BMI decreased slightly in the acamprosate group but increased in the placebo group. DISCUSSION Although acamprosate did not separate from placebo on any outcome variable in the longitudinal analysis, results of the endpoint and completer analyses suggest the drug may have some utility in BED.

Abstract
OBJECTIVE This study aimed to compare bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD) on clinically significant variables and examine the utility of once versus twice-weekly diagnostic thresholds for disturbed eating behaviors. METHOD 234 women with BN, BED, or PD were identified through self-report measures via an online survey and categorized based on either once-weekly or twice-weekly disturbed eating behaviors. RESULTS BN emerged as a more severe disorder than BED and PD. The three groups differed significantly in self-reported restraint and disinhibition and the BN and BED groups reported higher levels of depression than PD. For BN, those engaging in behaviors twice-weekly versus once-weekly were more symptomatic. DISCUSSION The BN, BED, and PD groups differed in clinically meaningful ways. Future research need to clarify the relationship between mood disturbances and eating behaviors. Reducing the twice-weekly behavior threshold for BN would capture individuals with clinically significant eating disorders, though the twice-weekly threshold may provide important information about disorder severity for both BN and BED.

Abstract
Obesity is a public health epidemic with medical, psychological and economic consequences. It continues to increase globally in prevalence and severity. Despite numerous behaviourally, medically or pharmacologically guided treatments, an effective non-surgical long-term treatment approach has not been identified. Bariatric surgery has surfaced as a viable option for a subset of individuals with medically complicated obesity who have failed non-surgical approaches. Pre-operative evaluation followed by post-operative, longitudinal follow-up by a multidisciplinary team specializing in surgery, medicine, psychiatry/psychology, exercise science and nutrition constitutes recognized and necessary standard of care for these complex patients. More information is needed regarding factors that interfere with successful outcomes and mechanisms of optimal follow-up for bariatric surgery patients to prevent and detect post-operative medical, psychological and social difficulties. We will review these issues with a focus on issues relevant to eating disorders professionals.

Abstract
The link between negative affect and binge eating in those with binge eating disorder (BED) has been well established. The present study examined the efficacy of a treatment for BED designed to increase recognition and regulation of negative emotion, replicating and extending a previous investigation (Clyne, C., & Blampied, N.M. [2004]. Training in emotion regulation as a treatment for binge eating: A preliminary study. Behaviour Change, 21, 269-281) by including a control group, a larger number of participants, and formal diagnoses rather than classifying binge eating symptomatology from self-report questionnaires. Twenty-three women diagnosed with subthreshold or full syndrome BED (using the Eating Disorders Examination) participated in a treatment program that focused on increasing emotional regulation skills. Each participant completed the Eating Disorders Examination Questionnaire, the Binge Eating Scale, the Emotional Eating Scale, and completed self-monitoring records of binge episodes. Binge abstinence rates following treatment (post-treatment and 1 year follow-up were 78% and 87% respectively) were comparable to other empirically supported treatments for BED. Other positive changes in eating and general pathology were observed. These effects were well-maintained up to 1 year later.

Abstract
OBJECTIVE Several findings support the hypothesis that there is a relationship between dissociation and eating disorders (EDs). The aims of this study were as follows: (1) to assess whether ED patients show a higher level of dissociation than healthy control (HC) individuals or psychiatric control patients with anxiety and mood disorders and (2) to investigate the effects of dissociation on ED symptoms, specifically binge eating behavior. METHOD Fifty-four ED patients, 56 anxiety and mood disorders control patients, and 39 HC individuals completed the Eating Disorder Examination Questionnaire and the Dissociation Questionnaire. Each participant was asked about the number of binge eating episodes he or she had experienced in the past 4 weeks. RESULTS The ED patients had higher levels of dissociation than both the psychiatric control group and the HC group. In the ED group, the number of binge episodes was related to the level of dissociation. DISCUSSION Dissociative experiences are relevant in EDs, and binge eating is related to dissociation. In patients affected by the core psychopathologic beliefs of EDs (overevaluation of shape and weight), dissociation may allow an individual to initiate binging behavior, thus decreasing self-awareness and negative emotional states, without having to deal with the long-term consequences of their actions.

Abstract
Increasing empirical evidence supports the validity of binge-eating disorder (BED) and its inclusion as a formal diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Contention exists regarding the criteria for BED, including whether, like bulimia nervosa (BN), it should be characterized by overvaluation of shape/weight. This study examined the significance of overvaluation for BED using two complementary comparisons groups. Participants were 324 women who completed self-report instruments as part of an Internet study. Analyses compared BMI, eating disorder (ED) features, and depressive levels in four groups: 123 overweight participants without ED, 47 BED participants who do not overvalue shape/weight, 101 BED participants who overvalue shape/weight, and 53 BN participants. Both BED groups had significantly greater ED psychopathology than the overweight group. Within BED, the group with overvaluation had significantly greater ED psychopathology and depressive levels despite no differences in binge eating. BED with overvaluation and BN groups differed little from each other but had significantly higher ED psychopathology and depressive levels than the other groups. Group differences existed despite similar age and BMI across the groups, as well as when controlling for group differences in depressive levels. These findings provide further support for the validity of BED and suggest that overvaluation of shape/weight, which provides important information about BED severity, warrants consideration as either a diagnostic specifier or as a dimensional severity rating. Although inclusion of overvaluation of shape/weight could be considered as a required criterion for BED, this would exclude a substantial proportion of BED patients with clinically significant problems.

Abstract
OBJECTIVE Assessment of disordered eating has uncertain validity across culturally diverse populations. This study evaluated Eating Disorder Examination Questionnaire (EDE-Q) performance in an ethnic Fijian study population. METHOD The EDE-Q was translated, adapted, and administered to school-going Fijian adolescent females (N = 523). A subsample (n = 81) completed it again within approximately 1 week. We assessed feasibility, internal consistency, and test-retest reliability; evaluated construct validity through factor analysis and correlation with similar constructs; and examined the marginal utility of an additional question on traditional purgative use. RESULTS Internal consistency reliability was adequate for the global scale and subscales (Cronbach's alpha = 0.66-0.91); retest reliability was adequate for both the languages (range of ICCs, 0.50-0.79, and of kappas, 0.46-0.81, excluding purging items). Construct validity was supported by significant correlations with measures of similar constructs. Factor analysis confirms multiple dimensions of eating disorder symptoms but suggests possible culture-specific variation in this population. The majority of respondents endorsing traditional purgative use (58%) did not endorse conventional EDE-Q items assessing purging. DISCUSSION The EDE-Q is a valid measure of eating disorder pathology for ethnic Fijian adolescent females and measures a unitary underlying construct.

Abstract
OBJECTIVE This study examined the clinical significance of loss of control (LOC) over eating in bariatric surgery patients over 24 months of prospective, multiwave follow-ups. METHOD Three hundred sixty-one gastric bypass surgery patients completed a battery of assessments before surgery and at 6, 12, and 24 months following surgery. In addition to weight loss and LOC over eating, the assessments targeted eating disorder psychopathology, depression levels, and quality of life. The study was conducted between January 2002 and February 2008. RESULTS Prior to surgery, 61% of patients reported general LOC; postsurgery, 31% reported LOC at 6-month follow-up, 36% reported LOC at 12-month follow-up, and 39% reported LOC at 24-month follow-up. Preoperative LOC did not predict postoperative outcomes. In contrast, mixed models analyses revealed that postsurgery LOC was predictive of weight loss outcomes: patients with LOC postsurgery lost significantly less weight at 12-month (34.6% vs 37.2% BMI loss) and 24-month (35.8% vs 39.1% BMI loss) postsurgery follow-ups. Postsurgery LOC also significantly predicted eating disorder psychopathology, depression, and quality of life at 12- and 24-month postsurgery follow-ups. CONCLUSIONS Preoperative LOC does not appear to be a negative prognostic indicator for postsurgical outcomes. Postoperative LOC, however, significantly predicts poorer postsurgical weight loss and psychosocial outcomes at 12 and 24 months following surgery. Since LOC following bariatric surgery significantly predicts attenuated postsurgical improvements, it may signal a need for clinical attention.

Abstract
OBJECTIVE Binge eating, a cardinal symptom of bulimia nervosa (BN) and binge eating disorder (BED), continues to pose challenges in terms of its definition and thus construct validity and clinical utility. This article reviews the available empirical data that support or refute the current DSM-IV-TR defined characteristics of a binge episode. METHOD A systematic literature review was conducted using Medline/PubMed electronic database on DSM-IV-TR defined binge characteristics and associated attributes. RESULTS Data support the current DSM guidelines indicating that binge episodes typically occur in less than 2 h. Size of binge episodes has variability across BN and BED diagnostic groups. Loss of control (LOC) continues to be a core feature of binge eating. Negative affect is the most widely reported antecedent. Strikingly, little is known about binge episodes among individuals with anorexia nervosa-binge/purge subtype. DISCUSSION Available empirical evidence supports the current DSM duration and LOC attributes of a binge episode in BN and BED. However, a more controversial issues is the extent to which size is important in the definition of a binge episode (e.g., subjective vs. objective episodes) across diagnostic categories and the extent to which binge size informs prognosis, treatment, and clinical outcomes. Further study of binge eating attributes in AN is needed.

Abstract
BACKGROUND Extremely obese bariatric surgery candidates report numerous episodes of both successful and unsuccessful dieting attempts, but little is known about the clinical significance of frequent dieting attempts in this patient group. METHODS The current study examined psychological and weight-related correlates of self-reported dieting frequency in 219 bariatric surgery candidates (29 men and 190 women). Prior to surgery, patients completed a battery of established self-report assessments. Patients were dichotomized into chronic dieters (n=109) and intermittent dieters (n=110) based on a median split of self-reported percent time spent dieting during adulthood. The two dieting groups were compared on demographics, eating and weight history, eating disorder psychopathology, and global functioning. RESULTS Chronic dieters had significantly lower pre-operative body mass indexes (BMIs), lower highest-ever BMIs, more episodes of weight cycling, and earlier ages of onset for overweight and dieting than intermittent dieters. After controlling for differences in BMI, chronic dieters were found to have statistically but not clinically significant elevations in eating concerns, dietary restraint, and body dissatisfaction than infrequent dieters. The two groups, however, did not differ significantly on depressive symptoms, self-esteem, or health-related quality of life; nor did they differ in binge-eating status. CONCLUSIONS Chronic dieting is commonly reported among extremely obese bariatric candidates and is not associated with poorer psychological functioning or binge eating and may be beneficial in attenuating even greater weight gain. Our findings provide preliminary data to suggest that requiring additional presurgical weight loss attempts may not be warranted for the vast majority of extremely obese bariatric candidates.

Abstract
OBJECTIVE This study tested the psychometric properties of two commonly used measures of dietary restraint, the Three Factor Eating Questionnaire and the Eating Disorder Examination Questionnaire. METHOD Restraint data from 512 overweight/obese participants with binge eating disorder (BED) were subjected to exploratory and confirmatory factor analyses. RESULTS Factor analyses of the restraint variables indicated a two-factor solution, interpreted as "Regimented" and "Lifestyle" restraint. Stepwise regression analyses revealed that Regimented restraint was more predictive of eating pathology, whereas Lifestyle restraint appeared to be protective of eating problems. Neither type of restraint was related to binge eating. Cluster analysis of the restraint dimensions yielded three distinct subgroups of patients who differed significantly on several important eating- and weight-related features. DISCUSSION Future research is needed to test the significance of these restraint constructs over time in both the development of obesity and binge eating problems as well as their treatment.

Abstract
Binge eating disorder (BED) was introduced in 1994 as a provisional eating disorder diagnosis. The core symptom is recurrent binge eating in the absence of inappropriate compensatory behaviors and/or extreme dietary restraint. This review examines the status of the literature on BED according to five criteria that have been proposed to determine whether BED warrants inclusion in the psychiatric nosology as a distinct eating disorder. We conclude that each of these criteria was met. There is a commonly accepted definition of and assessment approach to BED. The clinical utility and validity of BED have been established, and BED is distinguishable from both bulimia nervosa and obesity. BED should be included in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders.

Abstract
BACKGROUND Many obese subjects show relevant psychological distress. The aims of this study were to assess the psychopathological and clinical features of a sample of overweight or obese subjects seeking weight loss treatment and to evaluate the possible, significant associations between the levels of overweight and the specific and general eating disorder psychopathology. METHODS A total of 397 consecutive overweight (body mass index > or =25 kg/m(2)) patients seeking treatment for weight loss at the Outpatient Clinic for Obesity of the University of Florence were studied. The prevalence of binge eating disorder was assessed using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. All subjects were assessed through the self-report version of the Eating Disorder Examination Questionnaire, the Beck Depression Inventory, and the State-Trait Anxiety Inventory. RESULTS The current prevalence of binge eating disorder was 24.2%; 35% of the subjects were overweight during childhood. High prevalence rates of clinical significant depressive (38%) and anxious (71.5%) symptoms were observed. Binge eating disorder, the severity of specific eating disorder psychopathology, and depressive and anxious symptoms were not associated with the severity of overweight. CONCLUSIONS The severity of the specific and general eating disorder psychopathology does not predict the levels of overweight. A positive association between severe eating disorder psychopathology and clinical depression was observed.

Abstract
STUDY OBJECTIVES To study the prevalence of and symptoms of eating disorders in patients with narcolepsy. DESIGN We performed a case-control study comparing symptoms of eating disorders in patients with narcolepsy versus healthy population controls, using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN 2.1). To study whether an increased body mass index (BMI) could be responsible for symptoms of an eating disorder, we also compared patients with BMI-matched controls, using the SCAN as well as the Eating Disorder Examination-Questionnaire. SETTING University hospital. PATIENTS AND PARTICIPANTS Patients with narcolepsy/cataplexy (n = 60) were recruited from specialized sleep centers. Healthy controls (n = 120) were drawn from a population study previously performed in the Netherlands. Separately, 32 BMI-matched controls were recruited. INTERVENTIONS N/A. MEASUREMENTS AND RESULTS In total, 23.3% of the patients fulfilled the criteria for a clinical eating disorder, as opposed to none of the control subjects. Most of these were classified as Eating Disorder-Not Otherwise Specified, with an incomplete form of binge eating disorder. On the symptom level, half of the patients reported a persistent craving for food, as well as binge eating. Twenty-five percent of patients even reported binging twice a week or more often. When compared with BMI-matched controls, the significant increases persisted in symptoms of eating disorders among patients with narcolepsy. Except for a higher level of interference in daily activities due to eating problems in patients using antidepressants, medication use did not influence our findings. CONCLUSIONS The majority of patients with narcolepsy experience a number of symptoms of eating disorders, with an irresistible craving for food and binge eating as the most prominent features. Eating disorder symptomatology interfered with daily activities. These findings justify more attention for eating disorders in the treatment of patients with narcolepsy.

Abstract
OBJECTIVE Despite increasing use of the Eating Disorder Examination-Questionnaire (EDE-Q) in bariatric surgery patients, little is known about the utility and psychometric performance of this self-report measure in this clinical group. The primary purpose of the current study was to evaluate the factor structure and construct validity of the EDE-Q in a large series of bariatric surgery candidates. METHODS AND PROCEDURES Participants were 337 obese bariatric surgery candidates. Participants completed the EDE-Q and a battery of behavioral and psychological measures. RESULTS Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) produced a 12-item, 4-factor structure of the EDE-Q. The four factors, interpreted as Dietary Restraint, Eating Disturbance, Appearance Concerns, and Shape/Weight Overvaluation, were found to be internally consistent and converged with other relevant measures of psychopathology. DISCUSSION Factor analysis of the EDE-Q in bariatric surgery candidates did not replicate the original subscales but revealed an alternative factor structure. Future research must further evaluate the psychometric properties, including the factor structure, of the EDE-Q in this and other diverse populations and consider means of improving this measure's ability to best assess eating-related pathology in bariatric surgery patients.
