Comparing Two Group Therapy Treatments for Binge Eating Disorder

Comparison of Dialectical Behavior Therapy and Supportive Therapy for Binge Eating Disorder

This study will compare two different approaches for the treatment for Binge Eating Disorder.

Binge Eating Disorder (BED) is associated with impairments in physical, psychological, and social functioning. Research has revealed relationships between disordered eating and both low self-esteem and negative emotional states.

Participants in this study will complete assessment interviews regarding their eating disorder and associated problems. Similar assessments will be conducted at the end of the study. Participants will then be randomly assigned to one of two therapy groups. Participants in one group will focus on the role of self-esteem, self-awareness, and personal effectiveness in binge eating. Participants in the other group will focus on the role of negative emotions and binge eating. Both treatments will involve a 30 to 40 minute pre-treatment individual orientation session, followed by 20 weeks of weekly group therapy. Sessions will take place over 22 weeks, or approximately 6 months (18 weekly sessions followed by 2 biweekly sessions). Follow-up assessments will take place at 3 months, 6 months, and 12 months after study completion to assess maintenance of treatment effects.
