Theoretical framework to study exercise motivation for breast cancer risk reduction.

PURPOSE/OBJECTIVES To identify an appropriate theoretical framework to study exercise motivation for breast cancer risk reduction among high-risk women. DATA SOURCES An extensive review of the literature was conducted to gather relevant information pertaining to the Health Promotion Model, self-determination theory, social cognitive theory, Health Belief Model, Transtheoretical Model, theory of planned behavior, and protection motivation theory. DATA SYNTHESIS An iterative approach was used to summarize the literature related to exercise motivation within each theoretical framework. CONCLUSIONS Protection motivation theory could be used to examine the effects of perceived risk and self-efficacy in motivating women to exercise to facilitate health-related behavioral change. IMPLICATIONS FOR NURSING Evidence-based research within a chosen theoretical model can aid practitioners when making practical recommendations to reduce breast cancer risk.
