About this Calculator

The Eating Disorder Diagnostic Scale (EDDS) is a 22-item self-report scale for adolescents and adults (ages 13-65 years old) that simultaneously accesses for anorexia nervosa, bulimia nervosa, and binge-eating disorder by asking the respondent about body image, eating habits, and compensatory behaviors over the last 3-6 months. It was adapted by Stice et al. in 2000 from the validated structured psychiatric interview: The Eating Disorder Examination (EDE) and the eating disorder module of the Structured Clinical Interview for DSM-IV.

The EDDS is not an extensively studied questionnaire but it shows reliability and validity to be sufficiently sensitive to detect full and subthreshold diagnosis for anorexia nervosa, bulimia nervosa and binge eating disorder. EDDS is a continuous eating disorder symptom composite score, which means it’s ideally use for screening diagnosis and following treatment course, but not diagnostic. Eating disorders are accompanied by unhealthy attitudes about body shape and weight and co-occur with a number of other disorders, including depression, obsessive-compulsive disorders, anxiety disorders, and personality disorders.
