Objective: To present the twelve‐year outcome of binge eating disorder (BED) in 68 female inpatients compared to bulimia nervosa, purging type (BN‐P; N = 196). Method: Self and expert ratings focused on the beginning of therapy and the 12‐year follow‐up. Results: 36% of BED and 28.2% of BN‐P patients still received an eating disorder diagnosis at follow‐up. Differences between groups were small (Eating Disorder Inventory, Structured Inventory for Anorexic and Bulimic Syndromes, Hopkins Symptom Checklist, Beck Depression Inventory). Similar predictors for BED and BN‐P were identified. Psychiatric comorbidity was the predominant predictor of poor outcome in both diagnoses. Predictors for BED outcome were body dissatisfaction, sexual abuse, and impulsivity; self‐injury predicted BN‐P outcome. Conclusion: Course, outcome, and mortality were similar for BED and BN‐P. Both disorders had psychiatric comorbidity as the main predictor of outcome, and there was a diagnostic shift between BED and BN‐P over time, pointing to their nosological proximity. Data are relevant for the formulation of DSM‐V and ICD‐11 diagnostic criteria. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2008
