title: Purging disorder: a comparison to established eating disorders with purging behaviour.
abstract: This study is part of the larger Christina Barz Study, and it compared consecutively admitted patients with purging disorder (PurD; N = 225) with consecutively admitted patients with anorexia nervosa binge eating/purging subtype (AN-bp; N = 503) and bulimia nervosa purging subtype (BN-p; N = 756). Participants answered self-rating questionnaires on admission, at the end of inpatient treatment, and in a 5-year follow-up. Patients with PurD reported lower severity of general psychopathology than patients with AN-bp and lower severity of eating disorder symptoms than patients with AN-bp and BN-p on admission. Eating disorder symptoms of patients with PurD improved less during the course than of the comparison groups. Diagnostic perseverance was stronger in the PurD group than for patients with AN-bp; mortality was higher than for patients with BN-p. Predictors for better outcome differed for the groups. Our results provide new data about the long-term course of patients with PurD and indicate clinical relevance of the disorder.
