Step by Step: A Tailored Walking Intervention for Breast Cancer Survivors

More than two-thirds of breast cancer survivors are physically inactive. Inactivity is known
to negatively impact both morbidity and mortality, and is especially pronounced among cancer
survivors. Self-directed interventions targeting inactivity among breast cancer survivors
often report clinically insignificant behavior change. More successful behavior change
interventions have suggested that tailoring and, more recently, the fostering of intrinsic
motivation, may have improved outcomes. However, no interventions to date have utilized
these approaches to increase physical activity among sedentary cancer survivors.

AIM 1: Develop and test intervention (tailored) and comparison group (targeted) messages in
a sample of sedentary women to determine message acceptability.

AIM 2: Determine the efficacy of a 12-week tailored intervention to increase the number of
weekly steps taken among sedentary post-treatment breast cancer survivors compared to a
12-week, targeted intervention.
