Adapted Group-Based Dialectical Behaviour Therapy for Binge Eating in a Practicing Clinic: Clinical Outcomes and Attrition

Research evidence has been accumulating for the efficacy of dialectical behaviour therapy (DBT) for binge eating. However, support for its effectiveness and transportability beyond efficacy trials is lacking. The current study evaluated the feasibility of group‐based DBT for binge eating within the context of an operating community clinic. Women ages 24–49 (M = 39.60, SD = 9.53) with either subthreshold and full‐threshold binge eating disorder or bulimia nervosa formed the group and comprised the sample (n = 5 treatment completers). Positive outcomes included significant improvement in both binge eating and secondary outcomes with the Eating Disorder Inventory subscales of Bulimia, Ineffectiveness, Perfectionism and Interpersonal Distrust. Attrition was elevated compared with previous efficacy trials, suggesting the need for increased attention to how to improve retention within routine practice settings. Given our limited sample size, these findings are viewed as promising but preliminary. Copyright © 2012 John Wiley & Sons, Ltd and Eating Disorders Association.
