Objective: To investigate the effect of compliance and its predictors on outcome. Method: Sixty-two patients with DSM-III-R bulimia nervosa (BN) were randomly assigned to a self-care manual plus eight fortnightly sessions of guided self-change or 16 sessions of weekly cognitive behavioral therapy. Results: At the end of treatment, the group of high compliers had not achieved higher abstinence rates than low compliers regarding BN symptoms. At follow-up on average 43 weeks (SD = 26 weeks) after the end of therapy, those who had completed more exercises were more likely than low compliers to be abstinent from bingeing and vomiting. Those with a high frequency of vomiting at the beginning of therapy were less likely to use the manual while those with a longer duration of illness and higher levels of restraint were more likely to use the manual. Discussion: Exercises seem to be particularly important. Copyright © 2001 John Wiley & Sons, Ltd and Eating Disorders Association. [ABSTRACT FROM AUTHOR]

Objective In a study comparing eight sessions of fortnightly guided self-change (GSC) with 16 sessions of weekly cognitive behaviour therapy (CBT) in bulimia nervosa (BN) we examined pre-treatment predictors of outcome. Method Stepwise regression analyses were performed. Results In the GSC group, a lower pre-treatment binge frequency predicted better outcome at the end of treatment and at follow-up. In the CBT group, previous psychiatric disorder, absence of baseline depression and comorbidity predicted better outcome at the end of therapy and there was a trend for depression at baseline to predict a worse outcome at follow-up. Conclusion Those with more frequent bingeing may require a more intensive intervention than guided self-care. Copyright © 2000 John Wiley & Sons, Ltd and Eating Disorders Association.
