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.     

Importance of size in defining binge eating episodes in bulimia nervosa

OBJECTIVE: This study sought to determine if amount of food consumed is important in defining binge eating episodes in individuals with bulimia nervosa (BN). METHOD: Women (N = 30) with DSM-IV BN (OBN) and women (N = 25) who would have met DSM-IV criteria for BN except that their binge episodes were not objectively large (SBN) were recruited from the community. Subjects completed telephone interviews and questionnaires. RESULTS: Results demonstrated no significant differences between women with OBN and SBN in levels of dietary restraint, disinhibition, or hunger; no significant differences in general psychopathology; and significant differences in frequency of binge/purge episodes and impulsiveness. Differences in impulsiveness remained after controlling for frequency of binge/purge episodes. DISCUSSION: These results partially validate current diagnostic criteria for bulimia nervosa and elucidate one factor, impulsiveness, that may be important in understanding objective binge episodes in bulimia nervosa.     

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.     

Correlates of subjective and objective binge eating in binge-purge syndromes

OBJECTIVE: Research has begun to challenge the idea that a large amount of food is a diagnostically relevant distinction in classifying binge eating. This study examined the relationship between both objective and subjective (i.e., feeling out of control while eating an appropriate amount of food) binge eating frequency and factor analytically derived measures of dieting and psychopathology. METHOD: Participants were 40 women who were admitted for inpatient treatment for bulimia nervosa, anorexia nervosa, binge-purge type, or eating disorder not otherwise specified with binge-purge symptoms. RESULTS: Controlling for subjective binge frequency, neither the psychopathology nor the dieting factors were related to objective binge frequency. Controlling for objective binge frequency, dieting, but not psychopathology, was related to subjective binge frequency. There was no correlation between frequency of subjective and objective binge eating. DISCUSSION: The results are discussed in light of research on restrained eating. Implications for diagnosis and the role of loss of control in defining binge behavior are also discussed.     

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.     

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.     

Subjective binge eating with compensatory behaviors: A variant presentation of bulimia nervosa

Objectives:

To determine whether a variant bulimic‐type presentation, whereby one meets criteria for bulimia nervosa (BN) except that binge eating episodes are not objectively large (i.e., “subjective bulimia nervosa,” SBN), has comparable clinical severity to established eating disorders, particularly BN.

Method:

Treatment‐seeking adults with BN (N = 112), SBN (N = 28), anorexia nervosa restricting type (AN‐R) (N = 45), and AN‐binge/purge type (AN‐B/P) (N = 24) were compared.

Results:

Overall, SBN could not be meaningfully distinguished from BN. SBN and BN had equivalent eating pathology, depression and anxiety symptoms, low quality of life, impulsivity, Axis I comorbidity, and lifetime psychiatric history, and comparable clinical severity to AN‐R and AN‐B/P.

Discussion:

Individuals with SBN, differing from BN only by the smaller size of their binge eating episodes, had a form of eating disorder comparable in clinical severity to threshold AN and BN and warranting clinical attention. Health professionals and the community require greater awareness of this variant to optimize detection, treatment‐seeking, and outcomes. © 2012 by Wiley Periodicals, Inc. (Int J Eat Disord 2013)
