Abstract: Purpose: The year-round effects and mediators of a need-supportive physical activity program were examined. Methods: Sedentary employees (n = 92) of the university of Leuven received four months of physical activity coaching based on the Self-Determination Theory by bachelors in kinesiology (n = 30). The program consisted of five individual contact moments between coach and client (i.e. an intake session, three follow-up contacts and an outtake session), either face-to-face, by phone or by e-mail. Self-reports on physical activity, social support, self-efficacy and autonomous motivation were completed in an intervention condition (n = 92) and a control condition (n = 34) at three moments: before the intervention (pre-test), after the intervention (post-test) and one year after pre-test (follow-up-test). Results: Repeated measurement analyses showed that changes in physical activity were significantly different over time between the conditions. More specifically, the intervention condition increased in moderate, strenuous and total physical activity from pre- to post-test, whereas the control condition did not change. Additionally, the intervention condition increased in mild, moderate, strenuous and total physical activity from pre- to follow-up-test, while no changes occurred in the control condition. Bootstrapping analyses indicated that self-efficacy and autonomous motivation significantly mediated the intervention effect on physical activity from pre- to post-test, while social support significantly contributed to the long-term effect. Conclusion: This study provides evidence for the long-term effectiveness of a need-supportive physical activity program that might be efficient at the community level.
