Gaining Optimism After Weight Loss Surgery (GOALS) I: Proof-of-Concept Trial of a Positive Psychology-based Intervention to Increase Physical Activity After Bariatric Surgery

This study examines the feasibility, acceptability, and preliminary impact of an adapted positive psychology-motivational interviewing (PP-MI) intervention for physical activity among patients who have recently undergone bariatric surgery.

This study will test a positive psychology-motivational interviewing (PP-MI) intervention for physical activity promotion in patients who have had bariatric surgery within the past 6-12 months. The investigators will enroll 12 participants. Study participation includes attending three study visits (two at baseline, one after the intervention) and receiving a 10-week physical activity intervention that includes once-weekly phone calls, a written manual, and a Fitbit activity tracker. Primary outcomes are feasibility and acceptability of the intervention and study procedures. Secondary outcomes include pre-post changes in physical activity and other psychological, behavioral, and physiological outcomes.

Inclusion Criteria:

• Adult (age 18+)
• History of bariatric surgery (gastric bypass or sleeve gastrectomy) at one of two academic medical centers within the past 6-12 months
• Interest in increasing physical activity
• Low physical activity, defined as <200 minutes/week self-reported moderate- to-vigorous physical activity
• Access to telephone for study sessions
• Able to read and speak English

Exclusion Criteria:

• Cognitive deficits precluding participation or informed consent
• Illness likely to lead to death in the next 6 months
• Inability to be physically active (e.g., severe arthritis)
• Participation in another program targeting physical activity besides their standard offerings at the surgery center.
