A model was tested that included perceptions of social support and self-efficacy for leisure physical activity and leisure physical activity participation among adults with intellectual disabilities. Study participants included 152 adults with mild to moderate intellectual disabilities residing in a community-based group supported living setting. The hypothesized model fit the data. Social support and self-efficacy predicted physical activity participation, with self-efficacy serving as a mediator between social support and physical activity. Self-efficacy and social support for leisure physical activity are related to leisure physical activity participation among adults with intellectual disabilities receiving supported living services.
