A comparison of behavioral and cognitive-behavioral interventions for bulimia nervosa.

This study examined the relative efficacy of cognitive-behavioral and behavioral treatment approaches for bulimia nervosa. Female bulimic Ss were randomly assigned to cognitive-behavioral, behavioral, or attention placebo conditions. At posttreatment, 92% of the cognitive-behavioral group, 100% of the behavioral group, and 69% of the nonspecific self-monitoring group were abstinent from binge eating-purging. At 6-month follow-up, 69% of the cognitive-behavioral group, 38% of the behavioral group, and 15% of the nonspecific self-monitoring group were abstinent from binge eating and purging. The results support the conceptualization of bulimia nervosa as a multifaceted disorder best treated with an approach that directly addresses maladaptive cognitions, problematic behaviors, and the development of more adaptive coping skills.
