Predicting COVID-19 Vaccination Intention: The Roles of Institutional Trust, Perceived Vaccine Safety, and Interdependent Self-Construal

ABSTRACT

The purpose of this study is to explore the process through which institutional trust influences individuals’ vaccination intentions for a coronavirus vaccine. We collected data from a national representative sample of the Spanish population (N = 500) from an online research panel to test the proposed conceptual model. Results revealed a positive association of institutional trust with coronavirus vaccination intentions. This effect was mediated by perceived vaccine safety and positive attitude toward the vaccine. Furthermore, findings corroborate the moderating effect of interdependent self-construal on the indirect relationship between institutional trust and vaccination intention, implying that this effect was stronger for individuals with higher levels of interdependent orientation. Findings have implications for the development of evidence-based health communication strategies for encouraging COVID-19 vaccination.
