Despite the widespread use of the Eating Disorder Examination (EDE) as a primary assessment instrument in studies of eating and weight disorders, little is known about the psychometric aspects of this interview measure. The primary purpose of this study was to evaluate the factor structure of the EDE interview in a large series of patients with binge‐eating disorder (BED). Participants were 688 treatment‐seeking patients with BED who were reliably administered the EDE interview by trained research clinicians at three research centers. Exploratory factor analysis (EFA) performed on EDE interview data from a random split‐half of the study group suggested a brief 7‐item 3‐factor structure. Confirmatory factor analysis (CFA) performed on the second randomly selected half of the study group supported this brief 3‐factor structure of the EDE interview. The three factors were interpreted as Dietary Restraint, Shape/Weight Overvaluation, and Body Dissatisfaction. In this series of patients with BED, factor analysis of the EDE interview 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 interview in this and other eating‐disordered groups. The implications of these factor analytic findings for understanding and assessing the specific psychopathology of patients with BED are discussed.
