Eating Disorder Diagnostic Scale

The Eating Disorder Diagnostic Scale (EDDS) is a 22 item self-report questionnaire that assesses the presence of three eating disorders; anorexia nervosa, bulimia nervosa and binge eating disorder. 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 (SCID)16. In follow up studies of the reliability and validity of the EDDS it was shown to be sufficiently sensitive to detect the effects of eating disorders prevention programs, response to such programs and the future onset of eating disorder pathology and depression. The EDDS shows both full and subthreshold diagnoses for AN, BN and BED. EDDS is a continuous eating disorder symptom composite score
