The purpose of this study was to identify comlates of physical activity for sedentary. ethnic minority women and determine if these comlatcs were modified by an intervention. One hundred twenty-five women panicipated in a randomized. controlled trial of a walking program. The intervention was designed to alter social learning-based correlates through telephone counseling and mailings. Walking and correlates were assessed at baseline, 8-week post-test. and 5-month follow-up. Both intervention and control groups increased walking and decreased in respons of perceived barriers, self-efficacy. and enjoyment from baseline to post-test. and baseline to follow-up. Social support increased over time, with intervention participants reporting greater increases. Change in self-efficacy from baseline to follow-up was associated with increases in walking. The results provide some evidence that self-efficacy correlated with walking for participants. but 3 of 4 correlates were not positively influenced by the intervention.
