The study is designed to test a pilot intervention for bariatric patients who are starting to regain weight after the 1st year post-surgery. Dialectical Behavior Therapy (DBT), an empirically supported therapy for Borderline Personality Disorder, has also successfully been applied to patients with substance use and binge eating problems. The purpose of this study is to develop and test a group intervention based on DBT and cognitive behavioral therapy (CBT) techniques for patients engaging in these maladaptive behaviors after surgery with co-occuring weight gain.
