Objectives:
To develop and test an explicative model of leisure-time physical activity (LTPA), including 6 selected contributory factors: self-efficacy, self-regulation, social support, perceived physical environment, outcome-expectancy value, and policy beliefs.
Methods:
A social-ecological model of LTPA using the structural equation modeling technique was estimated in a regional, church-going sample of 649 African Americans.
Results:
The results indicated this model is good fit to the data. LTPA was associated with self-regulation and gender directly (P<.05) and social support, self-efficacy, perceived access to LTPA facilities, and positive outcome-expectancy value indirectly (P<.05).
Conclusions:
Multitiered interventions considering cultural relevance are recommended to improve LTPA engagement.
