Abstract
OBJECTIVE: The objective of this study was to compare the relative effectiveness of dialectical behavior therapy guided self-help (DBT-GSH) and DBT unguided self-help (DBT-USH) with an unguided self-help control condition in the treatment of binge-eating disorder (BED). METHOD:Seventy-one participants who met diagnostic criteria for BED based on Eating Disorder Examination (EDE) interview were randomly assigned to DBT-GSH, DBT-USH or active control USH for 12 weeks. Assessments took place at baseline, 12 weeks and 3-month follow-up. Outcome measures included the EDE to assess binge frequency, the EDE-Questionnaire (EDE-Q), the Brief Symptom Inventory, and the Short Form 6D. RESULTS: The overall completion rate was 65% at post-treatment and 63% at 3-month follow-up. Intention to treat analyses showed that participants in all three conditions reported significant reductions in binge frequency with large effect sizes. A similar pattern emerged for secondary outcome variables including eating disorder psychopathology, general psychological distress, and health-related quality of life. DISCUSSION: Self-help may be an effective way to disseminate DBT for BED. However, future research should evaluate DBT self-help using a larger sample size, possibly in a multisite design.
