The Eating Disorders Examination (EDE) is a semistructured interview designed to assess the specific psychopathology of patients with eating disorders. It is claimed that the EDE is more sensitive than standardized self-report questionnaire measures of the central features of bulimia, such as the Eating Disorder Inventory (EDI). This study examined the relative merits of the EDE, EDI, and Restraint Scale (RS) in discriminating between 15 female patients with bulimia nervosa and 15 highly restrained, nonbulimic controls. The groups differed significantly only on the total score and the Bulimia subscale of the EDI. Significant group differences were found on four of the five subscales of the EDE, the exception being the Restraint subscale. The EDE is recommended for future studies of treatment outcome as a superior measure of the core pathology of bulimia nervosa than standardized questionnaires.
