Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized controlled trial 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 compared to an enhanced usual care control.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 compared to an enhanced usual care control. The investigators will enroll and randomize 58 participants. Study participation includes attending four study visits (two at baseline, one at 10 weeks, and one at 24 weeks). Participants will be randomized either to a 10-week physical activity intervention that includes once-weekly phone calls, a written manual, and a Fitbit activity tracker, or provision of the Fitbit alone. Primary outcomes include the feasibility and acceptability of the intervention. Secondary outcomes include changes in physical activity and other psychological, behavioral, and physiological outcomes at 10 and 24 weeks compared to the control.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Positive Psychology-Motivational Interviewing Intervention

Participants will receive a written treatment manual with detailed information about each topic. The intervention consists of 10 weekly phone sessions (30 minutes each). Each session includes a new psychological skill designed to increase positive emotions experienced during physical activity, a motivational skill designed to boost physical activity, and setting a physical activity goal for the next week using information from the Fitbit. A motivational interviewing approach will be used for all topics.

Positive Psychology-Motivational Interviewing

Intervention Type BEHAVIORAL

Participants will receive a written treatment manual with detailed information about each topic. The intervention consists of 10 weekly phone sessions (30 minutes each). Each session includes a new psychological skill designed to increase positive emotions experienced during physical activity, a motivational skill designed to boost physical activity, and setting a physical activity goal for the next week using information from the Fitbit. A motivational interviewing approach will be used for all topics.

Physical Activity Education Control

Participants randomized to this condition will be provided with a Fitbit, and will be mailed educational materials about physical activity at 4 time points throughout the intervention period. They will not receive a manual or phone calls with an interventionist.
