Changes in enjoyment, self-efficacy, and motivation during a randomized trial to promote habitual physical activity adoption in bariatric surgery patients

PAI produced greater improvements in PA-related enjoyment, self-efficacy, and motivations than SC. The lack of association between objectively measured PA changes and psychological/motivational processes highlights the need for future research to identify which processes are most important for PA adoption and maintenance in bariatric surgery patients, and to determine whether the method used to measure PA affects the pattern of association.
