Protection Motivation Theory and Prevention of Breast Cancer: A Systematic Review

Breast cancer is a global health problem with a high rate of incidence and annual death. The protection motivation model (PMT) is a health psychology theory that has been introduced to motivate health behaviors using coping appraisal and threat appraisal. We aimed to systematically review the applicability of PMT to predict and improve the knowledge and intention (the patient's intent to undergo breast cancer screening with self/clinical breast exam or mammography) for protective behaviors among women. A systematic search was performed in May 2022 in electronic databases to investigate the role of PMT in the prediction of protection behaviors in addition to improving the knowledge about the prevention of breast cancer using specific keywords. The relevant studies were then included for data extraction. Seventeen articles including 7 interventional and 10 prediction studies were selected for data assessment. Findings demonstrated that PMT could be used to predict the rate of knowledge and intention about breast cancer risk among women. It was also shown that PMT could be considered as a framework for the prevention of breast cancer by changing the behaviors of individuals by training the participants. Fear arousal, response efficacy, and response cost were found as the main determinants of knowledge and intention rate. PMT can provide a useful framework to evaluate the factors associated with women's intentions about breast cancer. Periodical educational programs should be implemented to improve protection behaviors by increasing the intention of women to regular self-examination.
