An Integrated Health Belief Model: Predicting Uptake of the First COVID-19 Booster Vaccine

ABSTRACT

Public health campaigns have turned to the Health Belief Model (HBM) as a guiding framework for the past six decades. Carpenter’s 2010 HBM meta-analysis revealed important shortcomings as well as a path forward that has largely been ignored by recent COVID-19 research using this framework. Consistent with Carpenter’s recommendations, this study on the uptake of the first COVID-19 booster vaccine focused on the overlooked interactional processes of the original HBM founders. Our study used SEM and Hayes’s PROCESS 4.1 to explore the possibilities of the interdependent nature of the core three beliefs to form a model that is integrated. The study indicated that the core variables of the original HBM were significant predictors of the intent to take the first COVID-19 booster vaccine when considered in an interactional process framework. Our study results have implications for those designing public health advocacy campaigns regarding COVID-19 as it enters an endemic stage with future vaccines and medications.
