BACKGROUND: Previous studies have not reported the longer-term outcome of exposure-based treatments for bulimia nervosa. The current study evaluated the 3-year outcome of a randomized clinical trial that compared the additive efficacy of exposure-based versus nonexposure-based behavioral treatments (BT) with a core of cognitive-behavior therapy (CBT). METHODS:One hundred thirteen women participated in the original treatment trial and attended a 3-year follow-up assessment. Eating disorder diagnoses and primary, secondary, and tertiary outcome measures were assessed. The impact of treatment completion on symptomatology and the stability of treatment effects over time were evaluated. RESULTS: At the 3-year follow-up, 85% of the sample had no current diagnosis of bulimia nervosa and 69% had no current eating disorder diagnoses of any sort. Failure to complete CBT was associated with inferior outcome. No clear advantages were evident for participants who completed BT in addition to CBT. For subjects who did complete both CBT and BT, outcome was mostly stable from posttreatment to follow-up. No differential effects were found for exposure versus nonexposure-based treatments at 3-year follow-up. DISCUSSION: The results of the current study compare favorably with other treatment outcome studies for bulimia nervosa and suggest that treatment gains are maintained after 3 years.
