Mammography Screening and the Theory of Planned Behavior: Suggestions Toward an Extended Model of Prediction

Mammography screening is probably the most effective method for the early detection of breast cancer. Existing models of health behavior, such as the theory of planned behavior, could improve their predictive validity and, therefore, their ability to promote health-related interventions by identifying additional factors associated with health decision making. This review provides an overview of research on factors related to mammography screening within the context of the theory of planned behavior and identifies the potential benefits of adding motivational factors, such as time perspective, optimism, and risk perception, in an attempt to enhance its explanatory power.
