Eighteen patients with DSM-III-R bulimia nervosa were treated by providing them with supervision in the use of a self-help manual based on the cognitive behavioral treatment for the disorder. The patients were assessed before beginning the self-help program, and again 4 to 6 months later, using standardized measures of psychopathology. The findings were encouraging. At follow-up one half of the patients had ceased bulimic episodes and self-induced vomiting, and most of the remainder had made significant improvements. These preliminary findings, together with related published work, suggest that supervised self-help might be an appropriate first line treatment for patients with bulimia nervosa and that for many patients it could be sufficient. © 1994 by John Wiley & Sons, Inc.
