Cognitive-behavioral self-help for binge eating disorder: a controlled effectiveness study.

The aim of this study was to evaluate the effectiveness of 2 methods of administering a cognitive-behavioral self-help program for binge eating disorder. The study was designed to reproduce many of the conditions that apply in settings in which self-help interventions are most relevant. Seventy-two women with binge eating disorder were randomly assigned to 1 of 3 conditions for 12 weeks: pure self-help (PSH), guided self-help (GSH), or a waiting list (WL) control condition (followed by PSH or GSH). They were then followed up for 6 months. Both PSH and GSH had a substantial and sustained impact with almost half the participants ceasing to binge eat. There was little change in the WL condition. Cognitive-behavioral self-help may be of value both as an initial treatment for binge eating disorder and as a form of secondary prevention.
