Objective: While self-efficacy plays an important role in physical activity, relatively little research has examined this construct in minorities. This study identified theoretical correlates associated with self-efficacy among insufficiently active, hypertensive Black women. Methods: Correlates of self-efficacy to: (1) overcoming barriers to physical activity; (2) making time for activity; and (3) "sticking with" physical activity were studied. Results: Sixty-one women (M = 50.48 ± 4.2 years) participated. We accounted for 32% of the variance in confidence in overcoming barriers. Women confident in overcoming barriers reported less worry about physical activity. The TTM processes of change were also in the model: consciousness raising, environmental reevaluation, counter conditioning, and self-liberation. We accounted for 16% of the variance in "making time" self-efficacy. An aversiveness barrier (e.g., physical activity is boring, physical activity is hard work) was the dominant variable in the model. Confidence to 'stick with' physical activity was associated with self-reevaluation (i.e., reflection on how personal values correspond to behavior). Social support and competing demands were not associated with self-efficacy. Conclusions: Consistent with Social Cognitive Theory, results suggest that self-efficacy is behavior specific and each measure likely provides unique information. Practice implications: Interventions should be tailored to address specific self-efficacy types. © 2008 Elsevier Ireland Ltd. All rights reserved.
