Describe the research on the effectiveness of different forms of therapy for treating bulimia nervosa

Answer:

Although interpersonal therapy does not directly address eating disorders, it has emerged as a very successful form of treatment. This therapy focuses on difficulties in close relationships. Interpersonal therapy was studied in an investigation of the effectiveness of cognitive behavior therapy. The researchers used interpersonal therapy as a placebo control group in their study. They were interested in studying the effectiveness of cognitive behavior therapy and needed a credible placebo. At the end of the study, cognitive therapy was more effective than interpersonal therapy. However, at the 12-month follow-up, the interpersonal therapy group continued to improve. They equaled those of the cognitive behavior therapy group and outdistanced those in the behavior therapy alone group.
