Preventing Weight Regain After Bariatric Surgery

This study is looking at ways to help adults who have had weight-loss surgery (metabolic bariatric surgery) keep the weight off. It tests two behavioral interventions: one uses Acceptance and Commitment Therapy (ACT) to help you find your own reasons for being active and accept challenges, and the other provides general education about physical activity. Researchers want to see if the ACT-based approach, called "Acceptance and Commitment Therapy-Based Physical Activity Intervention," can increase your physical activity and prevent weight regain compared to the "Physical Activity Education Control." You might be able to join if you are between 18 and 64, had gastric bypass or sleeve gastrectomy 6 to 20 months ago, and haven't regained much weight. The study aims to enroll 164 participants.

Study design
This interventional study plans to enroll 164 participants. It compares two behavioral interventions to see which is more effective.
What's involved
Participants will engage in group-based workshops, receive email feedback, and have brief support calls. The study measures physical activity and weight regain over 12 months of treatment and an additional 6 months of follow-up.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 18 months in total, including 12 months of treatment and 6 months of follow-up after treatment ends.
