Objective: The purpose of this study was to determine if early response predicted remission at the end of a controlled trial. Method: Eighty adolescents with bulimia nervosa participated in an RCT comparing family‐based treatment and individual supportive psychotherapy. Response to treatment was assessed via self‐report of bingeing and purging. Remission was defined as abstinence from bingeing and purging for the last 28 days and measured by investigator‐based interview, that is, the Eating Disorder Examination. Results: Receiver‐operating characteristic analyses showed that, regardless of treatment, symptom reduction at session six predicted remission at posttreatment (AUC = 0.814 ( p < .001)) and 6‐month follow‐up (AUC = 0.811 ( p < .001)). Conclusion: Results suggest that adolescents with BN who do not show early reductions in bulimic symptoms are unlikely to remit at posttreatment or follow‐up. © 2008 by Wiley Periodicals, Inc.
