A new brief questionnaire, the Bulimic Investigatory Test, Edinburgh (BITE), for the detection and description of binge-eating is described. Data from two separate populations demonstrate satisfactory reliability and validity. The scale has measures of both symptoms and severity. All items in the DSM-III definition of bulimia and Russell's definition of bulimia nervosa are covered but the questionnaire is more than just an operationalised checklist of these diagnostic criteria.
