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.
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Prevention
Difference in weekly steps between intervention and comparison group at the end of the intervention (week 12).
The primary outcome will be measured using weekly step data as measured by a commercially available accelerometer. The primary outcome will be the difference in weekly steps between the intervention and comparison group at the end of the intervention (week 12).
