- Abstract
- The Health Belief Model (HBM) and the Theory of Planned Behaviour (TPB) are frequently used to predict cancer screening attendance. Although several meta-analyses have been conducted, none have compared these models in respect of mammography screening. A systematic review was performed between September and November 2016. Data were extracted from the search results and coded using a comprehensive data extraction template based on closed-ended questions on the key characteristics of the studies. No restriction was placed on the date of publication of studies. A total of 541 papers HBM studies, and 443 TPB studies, were recovered. Of these, 39 HBM studies and 14 TPB studies met the eligibility criteria for review. Between 34.7% and 63% of the variance in mammography screening participation was explained by HBM (mean R2 = 0.498). The explained variance for TPB ranged from 17% to 81% (mean R2 = 0.401). The HBM and TPB demonstrate positive predictive validity for mammography screening participation, although studies using TPB focus more intention to screen. Most studies examine the individual cognitive constructs of both models, displaying considerable heterogeneity in operationalising the individual constructs. Thus, the application of the complete models to predict mammography participation is under-reported.
