A randomized controlled trial compared a group of bulimic patients receiving 6 weeks of individual guided imagery therapy with a control group receiving standard care. Fifty participants who met the criteria for bulimia nervosa completed the study. Measures of eating disorder symptoms, psychological functioning and the response to the guided imagery experience were used. The guided imagery treatment substantially reduced bingeing and purging episodes; the imagery group had a 74% mean reduction of bingeing and a 73% reduction of vomiting. The imagery treatment also demonstrated improvement in attitudes about eating, dieting and body weight in comparison to the control group. In addition, the guided imagery group demonstrated improvement on psychological measures of aloneness and the ability for self-comforting. The study concludes that guided imagery is an effective treatment for bulimia nervosa, at least in the short-term.
