Stability of long-term outcome in bulimia nervosa: a 3-year follow-up.
We report on the 3-year course and outcome of patients with bulimia nervosa (BN), initially treated in an inpatient or day clinic setting. Patients were assessed by structured interviews (Structured Clinical Interview for DSM Disorders I and II and Structured Interview for Anorexia and Bulimia Nervosa) and questionnaires (Eating Disorder Inventory-2, Symptom Checklist-90-R, and Social Adjustment Scale) at time points of admission, discharge, and 3-month, 12-month and 36-month follow-ups. Data of 83.7% of the 43 patients were available. After 3 years, about one third of patients showed complete remission, one third showed partial remission, and one third still fulfilled all the criteria of BN. Most changes occurred during hospitalization. Remission status showed substantial fluctuation over time, with little correlation between time points of assessment (discharge and 3-month, 12-month, and 36-month follow-ups). A cluster analysis revealed four patterns of longitudinal symptom change. Day clinic and inpatient treatment are overall effective. Longitudinal and repeated assessments are necessary to validly measure outcome in BN.
