Gender differences in patients with binge eating disorder

OBJECTIVE: This study examined gender differences in patients with binge eating disorder (BED). METHOD: Participants were 182 adults (35 male, 147 female) who were consecutively evaluated for outpatient clinical trials and met criteria for BED as outlined in the 4th ed. of the Diagnostic and Statistical Manual of Mental Disorders. They were administered a battery of measures to examine developmental, eating and weight-related disturbances, and psychological features associated with BED. RESULTS: Men and women did not differ significantly on several developmental variables (age at first overweight, age at first diet, age at onset of regular binge eating, or number of weight cycles). Men had significantly higher current body mass index (BMI), highest adult BMI, and were significantly more likely to be classified as obese. Men and women did not differ significantly on measures of current eating disorder features (binge eating, eating concerns, weight or shape concerns) but women reported significantly greater body image dissatisfaction and drive for thinness. Men and women did not differ significantly on current depression or self-esteem but men reported a greater frequency of past drug abuse problems. DISCUSSION: Although men and women who present for treatment for BED show many similarities in current eating disorder features, we observed a number of gender differences on important developmental and physical variables as well as associated psychological features.     

A comparison of the binge eating scale, questionnaire for eating and weight patterns-revised, and eating disorder examination questionnaire with instructions with the eating disorder examination in the assessment of binge eating disorder and its symptoms

OBJECTIVE: The current study assesses concordance between self-administered measures and a diagnostic standard for assessment of binge frequency and diagnosis of binge eating disorder (BED) in a sample of binge eaters. METHOD: The Questionnaire for Eating and Weight Patterns-Revised (QEWP-R), Binge Eating Scale (BES), two items from the Eating Disorder Examination Questionnaire with Instructions (EDE-Q-I), and the Eating Disorder Examination (EDE) were administered. Participants were 157 adults volunteering for a clinical study, of whom 129 (79%) were diagnosed with BED using the EDE as the diagnostic standard. RESULTS: In the identification of BED, the QEWP-R yielded a sensitivity value of .74 and a specificity value of .35. The BES yielded a sensitivity value of .85 and a specificity value of .20. Frequency of binge eating days and episodes on the EDE-Q-I correlated highly with the EDE (.65 and .48, respectively; p < .001). DISCUSSION: The accuracy of diagnosis and symptomatology among self-administered questionnaires is variable. The BES and the QEWP-R performed satisfactorily as initial screens for the diagnosis of BED, but were less accurate in identifying non-BED individuals and the frequency of binge eating. The EDE-Q-I most accurately assessed the frequency of binge eating.     

Eating Disorder Examination-Questionnaire with and without instruction to assess binge eating in patients with binge eating disorder

OBJECTIVE: The current study examined whether adding written definitions and examples of binge eating to the Eating Disorder Examination-Questionnaire enhances its utility to assess binge frequency in patients with binge eating disorder (BED). METHOD: Eighty-nine women and men with BED completed the EDE-Q (without instruction; n = 37) or the EDE-Q-I (with instruction; n = 52) before receiving the EDE interview. Binge frequency was measured as the number of binge days (days on which one or more objective binge episodes occurred) over the past 28 days. RESULTS: Binge frequency correlations between the EDE and EDE-Q-I were strongly significant (r = .543, p = .000), whereas correlations between the EDE and EDE-Q were not significant (r = .197, p = .242). DISCUSSION: Providing brief detailed instructions improves the performance of the EDE-Q when evaluating binge eating in patients with BED. This suggests that, with relatively minor modifications, the EDE-Q may be a viable alternative to the EDE in assessing binge frequency in this population.     

Relation of binge eating age of onset to functional aspects of binge eating in binge eating disorder

OBJECTIVE: This study examined whether age of binge eating onset in binge eating disorder (BED) is related to affective binge eating antecedents and consequences. METHOD: Participants included women (N = 44) with BED who participated in a group cognitive-behavioral therapy (CBT) study. Measures included the Eating Hedonics Questionnaire, Beck Depression Inventory, Multidimensional Personality Questionnaire Negative Emotionality factor, Restraint Scale, Three-Factor Eating Questionnaire Restraint factor, and Eating Behaviors-IV. Participants were classified according to reported age of binge eating onset, with early onset defined as 13 years (LOB; n = 19). RESULTS: Compared with LOB, EOB was associated with reductions in postbinge subjective anxiety, but not depression. DISCUSSION: This study suggested that EOB in BED may be associated with binge eating as an affective means of coping, particularly with anxiety, and further supported age of binge eating onset as a clinically meaningful way to delineate BED subclassifications.     

Placebo response in binge eating disorder

OBJECTIVE: Placebo response in studies of binge eating disorder (BED) has raised concern about its diagnostic stability. The aims of this study were (1) to compare placebo responders (PRs) with nonresponders (NRs); (2) to investigate the course of BED following placebo response; and (3) to examine attributions regarding placebo response. METHOD: The baseline placebo run-in phase (BL) was part of a RCT investigating sibutramine hydrochloride for BED; it included 451 participants, ages 19-63, diagnosed with BED. Follow-up (FU) included 33 PRs. RESULTS:: In this study, 32.6% of participants responded to placebo (PRs = 147; NRs = 304). PRs exhibited significantly less symptom severity. At FU (n = 33), many PRs reported continued symptoms. CONCLUSION: PRs exhibited significantly less severe pathology than NRs. Placebo response in BED may transitory or incomplete. The results of this study suggest variable stability in the BED diagnosis.     

Satiety and test meal intake among women with binge eating disorder

OBJECTIVE: The purpose of the study was to measure test meal consumption and the changes in hunger and fullness during a test meal in obese individuals with and without binge eating disorder (BED) and normal-weight controls. METHOD: Twelve women with BED, 12 obese control participants, and 12 normal-weight control participants participated in two single-item test meal sessions. In one session participants were instructed to "binge," and the other eat a normal meal. Participants made ratings of hunger and fullness on visual analog scales after every 75-g increment of food. RESULTS: In comparison to obese or normal-weight controls, patients with BED consumed significantly more food to reach a similar level of fullness or hunger. CONCLUSION: Individuals with BED consumed significantly more food and showed blunted changes in hunger and fullness during both the binge and nonbinge meals. These findings suggest that individuals with BED may have disturbances in satiety that in some ways resemble those described among individuals with bulimia nervosa.     

Reliability of the Eating Disorder Examination in patients with binge eating disorder

OBJECTIVE: This study examined the interrater and test-retest reliabilities of the Eating Disorder Examination (EDE) in patients with binge eating disorder (BED). METHOD: Interrater reliability and short-term (6-14 days) test-retest reliability of the EDE were examined in two study groups of 18 patients with BED. RESULTS: Interrater reliability was excellent for objective bulimic episodes and days (correlations above .98) and very good for the EDE scales, albeit somewhat variable (correlations range from .65 to .96). Test-retest reliabilities were very good for objective bulimic episodes (.70) and days (.71) and were good (significant) for the EDE scales, albeit somewhat variable (correlations range from .50 to .88). Interrater reliability was excellent for subjective bulimic episodes and days but test-retest reliabilities were unacceptable. CONCLUSIONS: These findings support the reliability of the EDE for patients with BED. The EDE has utility for assessing the number of large binge episodes (objective bulimic episodes), as well as the number of days during which large binge episodes occurred. The EDE also demonstrates very good interrater and test-retest reliabilities for assessing the associated features of eating disorders in patients with BED. The results for subjective bulimic episodes are consistent with previous studies, suggesting that these eating behaviors may not be reliable indicators of eating disorders.     

Binge eating and binge eating disorder in a small-scale, indigenous society: the view from Fiji

OBJECTIVE: Although the cross-cultural prevalence of anorexia and bulimia nervosa has been investigated in multiple studies, little is known about the prevalence and correlates of binge eating and binge eating disorder (BED) cross-culturally. No published studies to date have explored BED in small-scale, indigenous, or developing societies. The current study investigated the prevalence and correlates of binge eating in a community sample of Fijian women living in rural Fiji. METHODS: Fifty ethnic Fijian women completed a self-report measure developed for this study on dieting and attitudes toward body shape and change, a Nadroga-language questionnaire on body image, and the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R). Their height and weight were also measured. Patterns of dieting, high body mass index (BMI), and attitudes toward eating and body image were compared between women with and without a history of binge eating. RESULTS: Ten percent of respondents reported at least weekly episodes of binge eating during the past 6 months and 4% endorsed symptoms consistent with BED. Binge eating in this sample was associated significantly with a BMI value above 35, a history of dieting, and a high concern with body shape. Binge eating was not associated with several markers of acculturation in this sample, although it was associated with a key, nontraditionally Fijian (i.e., acculturated) attitude toward the body. DISCUSSION: Binge eating occurred in a social context with traditions concerning weight and diet widely disparate from Western populations. However, correlates of binge eating in this sample suggest that nontraditional Fijian attitudes toward weight and body shape play a contributory role.     

Subtypes of binge eating disorder based on psychiatric history

OBJECTIVE: This investigation sought to identify subtypes of binge eating disorder (BED) based on history of mood disorder (MOOD) and substance use disorder (SUD). METHOD: Eighty-four women who met criteria for BED were administered semistructured interviews and completed self-report questionnaires assessing eating pathology, depressive symptoms, self-esteem, body dissatisfaction, and personality traits. RESULTS: Thirty-nine participants (46.4%) had a lifetime history of a SUD and 60 (71.4%) had a lifetime history of a MOOD. The SUD subtype was associated with a greater impulsivity and frequency of binge eating episodes compared with the no SUD subtype. The MOOD subtype participants reported greater distress, more psychopathology, less dietary restraint, lower self-esteem, more frequent binge eating, higher levels of negative affect, and more frequent trauma and abuse history than the no MOOD subtype. DISCUSSION: The results of this study indicate that subtypes of BED on the basis of MOOD and SUD may be associated with a more severe variant of the disorder.     

Emotional overeating and its associations with eating disorder psychopathology among overweight patients with binge eating disorder

OBJECTIVE: The current study examined emotional overeating in overweight patients with binge eating disorder (BED). A new measure--the Emotional Overeating Questionnaire (EOQ)--was developed to measure the frequency of overeating in response to emotions. The internal consistency, test-retest reliability, and factor structure of this measure were examined, and its associations with eating disorder psychopathology, depression, and gender were explored. METHOD: Two hundred twenty consecutive overweight (body mass index [BMI] > or = 25) treatment-seeking BED patients (48 men and 172 women) were administered the EOQ, which assesses overeating frequency in response to six emotions (anxiety, sadness, loneliness, tiredness, anger, and happiness). A subset of patients (n = 83) completed the measure again approximately 1 week later. BMI was measured, and participants completed measures of eating disorder psychopathology. RESULTS: The EOQ was internally consistent (alpha =.85), its items were significantly and moderately correlated (range .32 to .70) with each other, and principal components analysis revealed one factor accounting for 58% of the variance. The EOQ items and total score were characterized by good test-retest reliability (intraclass correlation coefficients [ICCs] ranged from .62 to .73). Significant correlations were found between the emotional overeating items and total score, and binge frequency, eating disorder features, and depressive symptomatology. Emotional overeating was unrelated to BMI, and men and women reported similar rates of emotional overeating. CONCLUSION: Emotional overeating was significantly associated with binge frequency, eating disorder features, and depression, but was not related to BMI or gender.     

Maintenance of binge eating through negative mood: a naturalistic comparison of binge eating disorder and bulimia nervosa

OBJECTIVE: To examine negative mood as a proximal antecedent and reinforcing condition of binge eating in binge eating disorder (BED) and bulimia nervosa (BN). METHOD: Using an ecological momentary assessment design, 20 women with BED, 20 women with BN, and 20 nonclinical control women were recruited from the community, provided with a portable minicomputer, and asked to rate their mood and list their thoughts at randomly-generated beep sounds and before, during, and after episodes of eating. RESULTS: In both eating disorder groups mood before binge eating was more negative than before regular eating and at random assessment. Binge eating was followed by a deterioration of mood. The BED group revealed less antecedent negative mood than the BN group and less concomitant negative cognitions about food/eating and stress. CONCLUSION: Affect regulation difficulties likely lead to binge eating in both disorders, but binge eating may not be effective for regulating overall mood.
