摘要: Background Cognitive-behavior therapy (CBT) is the most effective treatment to date for bulimia nervosa. The current study investigated effects of group CBT (including some interpersonal elements) bulimic clients. Method Twenty-nine patients completed Stirling Eating Disorder Scales, Beck Depression Inventory, and Anxiety Inventory at assessment, pretreatment, end treatment, 6 months follow-up. Symptom change was explored in two ways. Statistically significant determined using repeated-measures analyses variance clinically criteria proposed by Jacobson & Truax (1991, Journal Consulting Clinical Psychology, 59, 12–19). Results There an overall improvement dimensional measures restrictive attitudes behaviors (maintained 6-month follow-up), which closely matched changes behaviors. (but not anxiety) also targeted effectively. improvements psychological functioning were evident only assertiveness, but analysis clinical significance showed participants self-evaluation (self-directed hostility). Discussion Group broadly when treating nervosa, it does work all cases (and may lead enhancement characteristics cases). Tests statistical provide different information, can inform practice aid development treatments who respond less well best practice. © 2004 Wiley Periodicals, Inc. Int J Eat Disord 36: 363–375, 2004.
