简要总结
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.
详细描述
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.

研究组 & 干预措施
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.
干预措施: Positive Psychology-Motivational Interviewing Intervention (Behavioral)
结局指标
主要结局
Number of Intervention Sessions Completed
时间窗: 10 weeks
Feasibility will be measured by examining the number of completed intervention sessions. The intervention will be considered feasible if at least 7/10 sessions are completed, on average.
Ease and Utility of Intervention Sessions
时间窗: 10 weeks
Acceptability will be measured with ratings of ease and utility after each exercise, measured on a 10-point Likert scale (1=very difficult/not at all helpful, 10=very easy/very helpful). The intervention will be considered acceptable if average ease and utility ratings are at least 7/10.
