Examination of Personality Traits in Predicting COVID-19 Vaccine Hesitancy: A Community-Based Survey Study

Abstract

Vaccination has played an important role in combating the spread of the COVID-19 virus. The aim of the study is to investigate the effects of personality traits that may be associated with COVID-19 vaccine hesitancy. The study included 468 participants. A sociodemographic data form and Eysenck Personality Questionnaire Revised – Abbreviated Form (EPQR-A) were filled out via an online survey. The mean score of the EPQR-A psychoticism and lie subscales were significantly higher in unvaccinated participants. Further analyses revealed that having psychoticism personality and lying explicitly predicted the probability of being unvaccinated. These results suggest that there is a relationship between personality characteristics and attitude towards vaccination. Our findings may guide health care professionals and policy makers in achieving herd immunity. [ Psychiatr Ann . 2023;53(9):425–431.]
