The mediational role of trust in the healthcare system in the association between generalized trust and willingness to get COVID-19 vaccination in Iran

ABSTRACT

For some individuals, there appears to be some level of unwillingness in getting a COVID-19 vaccine which may be due to trust issues. The present study used a mediation model to investigate how trust is associated with an individual’s willingness to get COVID-19 vaccination among Iranians. A total of 10,843 Iranian adults were recruited in Qazvin province using a multistage stratified cluster sampling method. The survey was completed between February 19 and April 9, 2021. The findings showed that generalized trust was positively associated with trust in the healthcare system, trust in the healthcare system was positively associated with willingness to get COVID-19 vaccination, and generalized trust was positively associated with willingness to get COVID-19 vaccination. Also, trust in the healthcare system mediated the association between generalized trust and willingness to get COVID-19 vaccination. There were some significant demographic differences in COVID-19 vaccination willingness. The findings suggest that generalized trust plays a significant role in directly or indirectly influencing individuals’ willingness to get COVID-19 vaccine. Therefore, government bodies and health officials may utilize these findings to appeal in a more transparent and professional manner in encouraging individuals to get a COVID-19 vaccine. However, for those with lower trust levels (in general and in the healthcare system), the focus may be to re-build and/or regain the individuals’ trust through carefully planned transparent communication, information dissemination, and ethical education to help increase the uptake of COVID-19 vaccination.
