Application of the Health Action Process Approach Model in Predicting Mammography among Iranian Women

Background: This aim of this study was examining the application of the Health Action Process Approach Model (HAPA) in predicting diagnostic mammography among women over 40 years old in Iran.Methods: This was a cross-sectional study that was performed on four hundred women over 40 years old in health centers in Tehran between May to September 2017. The multi-stage cluster sampling were selected for sample research. The instrument was designed on based literature review about Health Action Process Approach (HAPA). Data were collected by self-report questionnaires and analyzed using statistical tests, t-test, correlation regression analysis. The predictors of diagnostic mammography were determined by the structures of the HAPA model.Results: The result regression analysis showed the diagnostic mammography behavior prediction rate, using the structures of the HAPA model was generally 60%.Conclusions: This study showed the effectiveness of the HAPA to predict diagnostic mammography in women over 40 years old. So, it seems examining mammography behavior and individuals' beliefs about breast cancer based on HAPA model is important in order to development of training programs and effectiveness interventions for breast cancer prevention.
