The study purpose was to determine how self-reported lifestyle physical activity levels, exercise self-efficacy and outcome expectancies, and health status differ by body mass index for persons with chronic pain. From U.S. clinics and community networks, 209 adults reporting chronic musculoskeletal pain were recruited for the cross-sectional survey. Data were analyzed using analysis of variance. Participants with self-described obesity reported the lowest physical activity, reduced exercise self-efficacy and positive outcome expectancies, and poorer health status. Promoting graded activity while addressing motivational factors from health behavior theory for people with chronic pain and obesity should be encouraged in rehabilitation programs.
