Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults who have undergone Roux-en-Y gastric bypass or sleeve gastrectomy within the last 8 to 20 months and have not regained more than 10% of their maximum weight lost.

Probably not a fit

Patients who have regained 10% or more of their maximum weight lost or cannot ambulate independently may not benefit from this study.

What this trial studies

This clinical trial aims to determine if a psychological intervention can enhance physical activity levels and prevent weight regain in adults who have undergone metabolic bariatric surgery. Participants will be assigned to either an Acceptance and Commitment Therapy (ACT)-based intervention or an educational control group, engaging in online workshops, homework assignments, and individual support calls over 12 months. The study will assess the effectiveness of the psychological approach in fostering internal motivation for physical activity and managing the discomfort associated with it. By comparing the two interventions, researchers hope to identify a more effective strategy for long-term weight maintenance post-surgery.

Why it matters

Potential benefit: If successful, this intervention could significantly improve the ability of bariatric surgery patients to maintain their weight loss and enhance their overall health and quality of life.

How similar studies have gone: Previous studies utilizing Acceptance and Commitment Therapy have shown promise in promoting health behavior changes, suggesting potential success for this approach.
