Abstract

Objective:

Investigate moderators of a randomized clinical trial of group Dialectical Behavior Therapy for Binge Eating Disorder (DBT-BED) compared to an active comparison group control (ACGT) on the post-treatment outcome of binge frequency after twenty 2-h weekly sessions.

Method:

Moderation analyses.

Results:

Participants were 101 adults with BED [mean (SD) age, 52.2 (10.6) years and BMI, 36.4 (8.6)]. Analyses identified two moderators of post-treatment outcome. Participants with (1) Avoidant Personality Disorder or (2) an earlier onset of overweight and dieting (<15 years old) evidenced significantly worsened outcome when treated with ACGT versus DBT-BED.

Discussion:

Participants with certain indicators of higher baseline pathology respond better to DBT-BED than ACGT at post-treatment. © 2011 by Wiley Periodicals, Inc. Int J Eat Disord 2012.
