THE INTERVIEW FOR THE DIAGNOSIS OF EATING DISORDERS IV - APPLICATION TO DSM-IV DIAGNOSTIC-CRITERIA

The authors describe the psychometric development of the fourth revisi on of the Interview for Diagnosis of Eating Disorders (IDED-IV). The I DED-IV was tested for the purpose of differential diagnosis of eating disorders, that is, anorexia nervosa, bulimia nervosa, and binge eatin g disorder. Evidence for internal consistency was found for symptom ra tings relevant to anorexia nervosa, bulimia nervosa, and binge eating disorder. Support was found for the content validity as well as the co ncurrent and discriminant validity of the IDED-IV. Finally, tests of t he interrater agreement for differential diagnosis of eating disorders found the IDED-IV to yield very reliable data. The authors conclude t hat the IDED-IV yields sufficiently reliable and valid data to be used for determining diagnoses in research studies and clinics specializin g in the treatment of eating disorders.
