BACKGROUND: The degree to which breast cancer survivors use behavioral processes of change has not been investigated. Additionally, the relationship between behavioral processes and other theory-based mediators of adult physical activity behavior has not been extensively studied among breast cancer survivors. The objectives of this study were to: (1) determine the extent to which breast cancer survivors use behavioral processes associated with physical activity behavior change, and (2) examine the inter-relationships between behavioral processes, self-efficacy, and physical activity behavior among breast cancer survivors.

METHODS: Sixty-nine breast cancer survivors completed surveys examining behavioral processes and exercise-specific self-efficacy. Six months later they completed a self-report physical activity questionnaire.

RESULTS: Findings showed the majority of breast cancer survivors did not use approximately half of the behavioral processes on a regular basis, and self-efficacy completely mediated the relationship between behavioral processes and physical activity.

CONCLUSION: Health care professionals may help enhance self-efficacy and ultimately increase physical activity behavior in breast cancer survivors by teaching behavior skills such as enlisting social support.
