Abstract

The purpose of this study is to explore the mediators associated with physical activity (PA) within the adoption and maintenance phase of a PA intervention trial among breast cancer survivors. Overall, 192 breast cancer survivors (average age = 55.9 years) were randomized to an Intervention or Control group. Both groups received 8 calls in the first 3-months, 3 monthly calls, and then entered a no-contact maintenance phase for the remaining 6-months. Assessments were completed at baseline, 3-months, 6-months and 12-months. On average, participants were 55.9 years of age (SD = 9.8) and 2.9 years since diagnosis (SD = 2.2). In the adoption phase, all significant univariate mediators (self-efficacy, cognitive and behavioral processes and decisional balance cons) were included in the multivariate model. Results suggest self-efficacy (ab = 13.56, SE = 7.04) and behavioral processes (ab = 36.10, SE = 12.22) were significant for PA adoption. No mediators were identified in the maintenance phase. In the adoption phase, there were significant indirect effects of group on PA adoption through self-efficacy and behavioral processes. There were no indirect effects of group on PA maintenance.
