Cognitive-behavioral treatment with and without response prevention for bulimia.
We compared cognitive-behavior therapy (CBT) with and without exposure and response prevention (ERP) in the treatment of eating disorder patients who both binged and purged, and reported abnormal attitudes concerning body weight and shape. Both treatments produced significant and comparable reductions in binge-eating and purging, eating patterns, and attitudes about weight and shape at posttreatment. Treatment effects were generalized to improvements in different measures of general psychopathology, and were maintained over follow-ups of 3 and 12 months. The findings are consistent with prior research showing that CBT is an effective treatment for patients with the core features of bulimia nervosa. Furthermore, the data suggest that the addition of in-session exposure and response prevention does not enhance the effectiveness of the basic CBT program.
