Three psychological treatments for bulimia nervosa. A comparative trial.
The specificity and magnitude of the effects of cognitive behavior therapy in the treatment of bulimia nervosa were evaluated . Seventy-five patients who met strict diagnostic criteria were treated with either cognitive behavior therapy , a simplified behavioral version of this treatment , or interpersonal psychotherapy . Assessment was by interview and self-report question naire , and many aspects of functioning were evaluated . All three treatments result ed in an improvement in the measures of the psychopathology .  Cognitive behavior therapy was more effective than  interpersonal psychotherapy  in modifying the disturbed attitudes to shape and weight , extreme attempts to diet , and self-induced vomiting .  Cognitive behavior therapy was more effective than  behavior therapy in modifying the disturbed attitudes to shape and weight and extreme dieting , but it was equivalent in other respects . The findings suggest that cognitive behavior therapy , when applied to patients with bulimia nervosa , operates through mechanisms specific to this treatment and is more effective than both interpersonal psychotherapy and a simplified behavioral version of cognitive behavior therapy
