This study examined the correlates of self-efficacy for physical activity in African American women. In bivariate analyses, self-efficacy was higher among women reporting fewer social role constraints, more positive perceptions of physically active women, more positive sense of community, better perceived health, and higher levels of physical activity. In a simultaneous multivariate model, more positive perceived health status (p = .001), higher physical activity level (p = .007), and lower social role constraint (p = .02) were independently associated with higher self-efficacy. Thus, physical activity interventions for African-American women should include strategies to decrease social role constraint and offer safe activities for women with health conditions hindering physical activity.
