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.     

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.     

Diagnosis of binge eating disorder: Discrepancies between a questionnaire and clinical interview

Binge eating is a common problem among obese individuals, and a simple, accurate way to identify obese binge eaters is needed. This study measured the concordance of the Binge Eating Scale (BES) and the Eating Disorder Examination (EDE). Women seeking obesity treatment (N = 126) were identified as binge eaters or nonbinge eaters using the BES, and then interviewed by clinicians blind to BES score using the EDE, a semistructured interview considered to be the “gold standard” for eating disorder diagnosis. The BES accurately identified nonbinge eaters; 39 of 42 (92.9%) BES-identified nonbinge eaters were confirmed by the EDE. However, the BES did not accurately identify binge eaters; only 43 of the 83 (51.8%) BES-identified binge eaters were confirmed by the EDE. Reasons for the discrepancy between the BES and the EDE in the identification of binge eaters were explored, and modifications to the BES that might improve its accuracy were considered. © 1995 by John Wiley & Sons, Inc.     

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.     

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.     

Predictors of relapse following successful dialectical behavior therapy for binge eating disorder

OBJECTIVE: To identify predictors of relapse at 6-month follow-up for women with binge eating disorder (BED). METHOD: Participants were 32 women with BED who had initially achieved abstinence from binge eating after 20 weeks of dialectical behavior therapy (DBT) adapted for patients with BED. Posttreatment predictor variables included the subscales Restraint, Weight Concerns, and Shape Concerns from the Eating Disorders Examination (EDE), the Emotional Eating Scale score, the Rosenberg Self-Esteem Scale, body mass index, and early versus late age of binge eating onset. RESULTS: The largest effect sizes for predicting relapse were found with early onset of binge eating and higher EDE Restraint scores. DISCUSSION: Previous findings that earlier age of onset (age 16 years or younger) is linked to less successful treatment outcome are now extended to the 6-month follow-up assessment. The finding that higher restraint scores after treatment predict relapse adds to the literature concerning the role of restraint in patients with BED.     

On the relation of flexible and rigid control of eating to body mass index and overeating in patients with binge eating disorder

OBJECTIVE: To examine the relationship of flexible and rigid dimensions of restrained eating to body mass index (BMI) and overeating in outpatients with binge eating disorder (BED). METHOD: Participants were 148 consecutive outpatients who met criteria for BED. The Three-Factor Eating Questionnaire (TFEQ) was administered to assess Cognitive Restraint, Hunger, and Disinhibition. The TFEQ also contains two Cognitive Restraint subscales--Flexible Control and Rigid Control. The Eating Disorder Examination-Questionnaire version (EDE-Q) was administered to assess frequency of different forms of overeating during the past 28 days and the attitudinal features of eating disorders. RESULTS: Flexible Control and Rigid Control were significantly correlated with each other. They were both negatively correlated with BMI, but neither was significantly correlated with the frequency of binge eating or other forms of overeating. In addition, Flexible Control and Rigid Control predicted almost the same amount of variance in BMI. DISCUSSION: BED patients exhibit flexible and rigid control of eating that is related to BMI, but not to the frequency of binge eating or other forms of overeating. Results of the present study provide preliminary evidence that flexible and rigid control of eating may not be a useful distinction in BED patients. However, increased restraint, regardless of type, may prove to be of benefit with regard to weight control and may not have adverse effects on binge eating in obese BED patients.     

Telephone-based guided self-help for binge eating disorder: A feasibility study

This feasibility study describes a novel form of guided self-help for treating binge eating disorder (BED). Over a 3-month period, a lay therapist provided first weekly (for 1 month) and then biweekly telephone-based guidance to supplement a self-help program. Eligible participants met DSM-IV criteria for BED, based on the Eating Disorder Examination (EDE). Of 9 women initially admitted into the study, 7 completed the self-help program. Upon completion, outcome was determined using the EDE-Questionnaire and the Brief Symptom Inventory (BSI). Binge eating frequency decreased markedly; BSI scores also decreased significantly. All women reported high levels of satisfaction with the intervention. Participants commented favorably about the flexibility, accessibility, and autonomy afforded by the telephone-based administration of guidance. Results suggest that telephone-based guided self-help is a viable mode of service delivery for some women with BED. Recommendations are made for further improvement of this form of self-help. © 1997 by John Wiley & Sons, Inc. Int J Eat Disord 21: 341–346, 1997.     

Subthreshold binge eating disorder

OBJECTIVE: To examine the clinical features of subthreshold binge eating disorder (BED). METHOD: Participants were recruited directly from the community as part of an ongoing study of risk factors for BED. Forty-four women with subthreshold BED were compared with 44 women with BED and 44 healthy controls on demographic characteristics, body mass index (BMI), eating disorder symptomatology, and psychiatric distress. Diagnoses were established using the Eating Disorder Examination (EDE). Participants completed the EDE-Questionnaire, the Brief Symptom Inventory, and were measured and weighed. RESULTS: Adjusting for significant group differences in BMI, the two eating disorder groups did not differ significantly on measures of weight and shape concern, restraint, psychiatric distress, and history of seeking treatment for an eating or weight problem. DISCUSSION: Given the importance of diagnostic status for access to treatment, further evaluation of the severity criterion specified for BED is needed.     

Self-efficacy in overweight individuals with binge eating disorder

OBJECTIVE: To evaluate the relationship between self-efficacy judgments in obese individuals with binge eating disorder, "borderline" binge eating disorder, and no binge eating problems. RESEARCH METHODS AND PROCEDURES: Before participation in a residential weight management program, 79 male and female subjects were administered the Weight Efficacy Lifestyle Questionnaire (WEL) and the Binge Eating Scale (BES). Based on DSM-IV diagnostic questions, subjects were categorized as BED, Borderline BED, or non-BED. RESULTS: Krusal-Wallace Rank-Order analysis of variance revealed significant negative associations between binge eating and total WEL scores as well as the subscales of Negative Emotions, Social Pressure, Physical Discomfort, and Positive Activities. Differences were significant between the BED and the Borderline BED groups with the exception of the Social Pressure scale and the Total WEL scores. BED diagnosis as well as severity of binge eating were strongly associated with low self-efficacy ratings. DISCUSSION: These results indicate that obese individuals with binge eating disorder demonstrate lower self-efficacy than those without this condition and that self-efficacy is related to the severity of binge eating.     

Predictors of treatment outcome for binge eating disorder

OBJECTIVE: The purpose of this study was to identify predictors of short-term treatment outcome for individuals with binge eating disorder (BED). METHOD: Fifty women who met DSM-IV criteria for BED were enrolled in a manual-based group cognitive-behavioral therapy that consisted of fourteen 1-hr sessions over an 8-week period. Baseline measures included the frequency of self-reported binge eating from the Eating Behaviors-IV (EB-IV), severity of binge eating and dietary restraint using the Binge Eating Scale (BES) and Three-Factor Eating Questionnaire (TFEQ), depressive symptoms as assessed by the Beck Depression Inventory (BDI) and the Hamilton Depression Rating Scale (HDRS), and self-esteem as measured by the Rosenberg Self-Esteem Questionnaire (RSEQ). RESULTS: Logistic regression analyses indicated that the baseline frequency of self-reported episodes of binge eating that were objectively large predicted the likelihood of such episodes at the end of treatment. No variables predicted the likelihood of binge eating episodes that were objectively and subjectively large at the conclusion of treatment. DISCUSSION: This study indicates that the frequency of binge eating episodes at baseline is predictive of outcome status at the end of treatment, suggesting that meaningful prognostic factors in BED are identifiable.     

The diagnostic validity of the criteria for binge eating disorder

OBJECTIVE: This paper considers whether the criteria currently used to classify the diagnosis of binge eating disorder (BED) are valid and appropriate. METHOD: We review evidence that reflects on the validity of the current criteria for binge eating episodes and BED, using literature retrieved through major psychology and psychiatry search engines (e.g., PsycInfo, PubMed). RESULTS: Evidence from experimental research points to the relative importance of episode frequency, the amount of food consumed at episodes, the subjective sense of loss of control over eating, and several additional criteria associated with binge episodes in BED. Evidence on the differences in psychopathology between BED and bulimia nervosa and between BED and obesity without binge eating, as related to diagnostic criteria, is reviewed. CONCLUSION: Although evidence concerning the diagnostic criteria of BED is mixed, broadening certain diagnostic criteria for binge eating episodes and BED might more accurately reflect the research literature and increase the number of individuals eligible for inclusion in treatment programs.     

Using the eating disorder examination to identify the specific psychopathology of binge eating disorder

OBJECTIVE: The clinical features of binge eating disorder (BED) are not well established. Therefore, a comprehensive assessment of the specific psychopathology of BED as compared to anorexia nervosa (AN) and bulimia nervosa (BN) is warranted. This comparison was the aim of the present study. METHOD: Detailed ratings from an investigator-based interview, the Eating Disorders Examination (EDE), were compared across three groups of female patients: those with BED, AN, and BN, as well as normal-weight and overweight control subjects. RESULTS: When comparing BED to AN and BN, patients with BED had lower levels of restraint, eating concerns comparable to AN patients but lower than BN patients, and weight and shape concerns comparable to BN patients but higher than AN patients. Significantly more eating disorder psychopathology was found for BED patients as compared to the overweight controls on all bar the EDE restraint subscale. On the majority of individual EDE items, BED patients' scores were similar to those of AN and BN patients, including importance of shape and weight in self-evaluation and preoccupation with shape and weight. No significant relationship was found between BED patients' degree of overweight and eating psychopathology. DISCUSSION: Our findings support the status of BED as an eating disorder and suggest that the elevated EDE scores reflect the combined impact of being objectively overweight and having disordered cognitions and behaviors about eating, shape, and weight.     

Different methods for assessing the features of eating disorders in patients with binge eating disorder: a replication.

OBJECTIVE: To compare different methods for assessing the features of eating disorders in patients with binge eating disorder (BED). RESEARCH METHODS AND PROCEDURES: A total of 47 participants with BED were administered the Eating Disorder Examination (EDE) Interview and completed the EDE-Questionnaire (EDE-Q) at baseline. A total of 37 participants prospectively self-monitored their eating behaviors daily for 4 weeks and then completed another EDE-Q. RESULTS: At baseline, the EDE and the EDE-Q were significantly correlated on frequencies of objective bulimic episodes (binge eating), overeating episodes, and on the dietary restraint, eating concern, weight concern, and shape concern subscales. Mean differences in the EDE and EDE-Q frequencies of objective bulimic episodes and overeating were not significant but scores on the four subscales differed significantly, with the EDE-Q yielding higher scores. At the 4-week point, the EDE-Q retrospective 28-day assessment was significantly correlated with the prospective daily self-monitoring records for frequency of objective bulimic episodes and the mean difference between the methods was not significant. The EDE-Q and self-monitoring findings for subjective bulimic episodes and objective overeating differed significantly. DISCUSSION: In patients with BED, the three assessment methods showed some areas of acceptable convergence.     

Cognitive-behavioral therapy for adolescents with binge eating syndromes: a case series

OBJECTIVE: Published empirically based studies of psychotherapies for bulimia nervosa (BN) have been conducted solely with adult populations. The current study extends the extant literature by piloting a version of cognitive-behavioral therapy (CBT) for BN adapted for an adolescent population. METHOD: The participants were referred for treatment for binge eating and purging behaviors at a university clinic. Patients received pretreatment and posttreatment interviews assessing the frequency of their binge eating and purge behaviors, and they also completed pretreatment and posttreatment assessments with the Eating Disorders Examination (EDE). RESULTS: Results indicated significant reductions in the frequency of binge eating from pretreatment to posttreatment. Furthermore, all subscale scores of the EDE showed significant declines from pretreatment to posttreatment. CONCLUSION: The authors concluded that CBT adapted for adolescents with bulimic symptoms appears to be a promising intervention worthy of further study in adolescents.     

Assessment of binge eating in overweight youth using a questionnaire version of the Child Eating Disorder Examination with Instructions

OBJECTIVE: Existing self-report methods for assessing eating disorder (ED) symptoms in youth do not adequately measure binge eating and lack sufficient psychometric support. The Youth Eating Disorder Examination-Questionnaire (YEDE-Q), a self-report version of the Child Eating Disorder Examination (ChEDE), was designed to assess the spectrum of ED psychopathology in youth. METHOD: The YEDE-Q was compared to the ChEDE and the Questionnaire for Eating and Weight Patterns-Adolescent version (QEWP-A) in a sample of 35 overweight adolescents aged 12-17. RESULTS: The YEDE-Q showed significant agreement (ps < .001) with the ChEDE on all four subscale scores, the global score, and measurement of objective bulimic episodes. The YEDE-Q and the QEWP-A showed significant agreement (ps < .001) on the measurement of shape and weight concerns. CONCLUSION: The YEDE-Q appears promising in the assessment of eating-related pathology in overweight adolescents, but remains in need of validation in children and ED populations.     

Detailed analysis of binges in obese women with binge eating disorder: Comparisons using multiple methods of data collection

OBJECTIVE: This study compares multiple methods of assessing food intake in obese women with binge eating disorder (BED). METHOD: Twelve women meeting BED criteria completed six random 24-hour dietary recalls, engaged in a laboratory binge eating episode, and completed the EDE interview. RESULTS: There was not a significant difference in total or macronutrient intake when binge eating episodes were assessed via the recall and laboratory methods. However, within-individual correlations were low for the size of different binge eating episodes collected by the two methods. Significantly more calories were consumed during objective than during subjective binges, and significant differences in macronutrient composition were observed. Meal patterning data collected by the EDE and the recalls were comparable. CONCLUSION: The findings suggest only moderate agreement between the methods that were examined. Future investigations with larger sample sizes are needed to examine the relationship among these different methods of assessing food intake.     

Timing and sequence of the onset of overweight, dieting, and binge eating in overweight patients with binge eating disorder

OBJECTIVE: To examine the self-reported sequence and timing of onset of overweight, binge eating, and dieting in adult patients diagnosed with binge eating disorder (BED). METHOD: Participants were 284 treatment-seeking adults (73 men and 211 women) who met DSM-IV research criteria for BED. Patients were interviewed with structured diagnostic interviews and were queried regarding history of overweight, dieting, and binge eating behaviors. Questionnaires were also administered to assess current eating disturbances, body dissatisfaction, and general functioning. Participants were classified as Overweight First, Binge First, or Diet First, and the three groups were compared on developmental sequence and using the battery of measures. RESULTS: Sixty-three percent of the 284 participants reported becoming overweight prior to the onset of dieting or binge eating. Participants who reported they were overweight first had significantly greater BMI at the time of assessment. The 16% of the participants who reported binge eating first were significantly younger at the onset of BED diagnosis and reported significantly less dietary restraint. Onset order differed significantly by gender; proportionally more women (25%) than men (11%) reported that dieting preceded overweight or binge eating. CONCLUSION: Weight problems preceded dieting and binge eating behaviors for a majority of treatment-seeking overweight participants diagnosed with BED.     

The prevalence of binge eating disorder and borderline personality symptomatology among gastric surgery patients

In this study, we examined the prevalence of binge eating disorder (BED) and borderline personality disorder (BPD) in a sample of 121 candidates seeking surgery for obesity. In this predominantly female sample (85.9%), according to the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R), the prevalence of BED was 6.5%. As for the prevalence of BPD, 14.0% exceeded the clinical cut-off score on the Self-Harm Inventory (SHI), 14.0% exceeded the clinical cut-off score on the borderline personality scale of the Personality Diagnostic Questionnaire-4 (PDQ-4), and 7.4% exceeded the clinical cut-off score on the McLean Screening Inventory for Borderline Personality Disorder (MSI-BPD). Overall, 24.8% of the sample exceeded the clinical cut-off on at least one measure of BPD whereas only 3.3% exceeded the clinical cut-off on all three measures. In addition, there was a significant inverse relationship between the discrepancy between highest and lowest adult body mass index, and scores on the PDQ-4 and the MSI-BPD. The authors discuss the implications of these findings.     

Characterization of eating disordered behavior in obese binge eaters

In the present study, the Eating Disorder Examination (EDE), a clinical interview designed to characterize the psychopathohgy specific to eating disorders, was administered to 17 obese women seeking treatment for binge eating problems. Subjects also completed questionnaires to assess binge severity, depression, and weight history. Obese binge eaters obtained EDE subscale scores that did not differ from those reported for normal weight bulimia nervosa patients on the Overeating, Shape Concern, Weight Concern, and Eating Concern Sub-scales of the EDE; however, bulimia nervosa patients had higher scores on the EDE Restraint Subscale. Questionnaire data indicated that obese binge eaters had considerable depressive symptomatology and that early onset obesity, frequent weight losses, and family histories of obesity were common. These findings suggest that obese binge eaters and bulimia nervosa patients have similar levels of eating disorders psychopathohgy, but that future research directly comparing overweight and normal weight patients is needed.
