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. © 2004 by Wiley Periodicals, Inc. Int J Eat Disord 36: 434–444, 2004.
