Studies have shown CBT to be quite effective when used with eating disorder patients, particularly those with bulimia nervosa or binge eating disorder. In fact, cognitive behavioral therapy is said to be more effective for these disorders than any other form of talk therapy. In one study, 37% of people completely abstained from bingeing after receiving CBT that focused on the disorder. Other therapies show less promising results. One alternative, dubbed interpersonal therapy, did demonstrate similar results, but it took a much longer time to get there. Cynthia Bulik, PhD., director of the University of North Carolina Eating Disorder Program at Chapel Hill, said, “CBT is associated with the best outcome for bulimia nervosa.”
