Effects of Peer Support and Therapist Contact on Long-Term Weight Loss

This study evaluated the effectiveness of two posttreatment programs designed to enhance the maintenance of weight loss. Eighty-five obese clients were randomly assigned to either (a) behavior therapy plus a peer-support maintenance program, (b) behavior therapy plus a therapist-contact maintenance program, or (c) behavior therapy only. At a 7-month follow-up session, the therapist-contact program resulted in significantly greater maintenance of weight loss compared with the peer support and behavior therapy only conditions. However, by the time of an 18-month follow-up assessment, overall relapse rates were equivalent across conditions.
