The Role of Perceived Risk in the Relationship Between Disgust Sensitivity and COVID-19 Vaccine Hesitancy.

Background: Despite widespread availability of COVID vaccines and evidence of their efficacy, vaccine hesitancy remains prevalent. Several studies have examined the relationship between disgust sensitivity and vaccine hesitancy. Although results from studies using data collected prior to the COVID pandemic indicate that higher disgust sensitivity is related to greater vaccine hesitancy, results from studies using data collected during the COVID pandemic are equivocal. The present study examined whether perceived risk of contracting COVID moderated the relationship between disgust sensitivity and vaccine hesitancy.

Methods: Participants ( = 152) completed self-report measures of disgust sensitivity, perceived risk of contracting COVID, and COVID vaccine hesitancy (defined as both vaccine confidence and vaccine complacency).

Results: Perceived risk of contracting COVID significantly moderated the relationship between disgust sensitivity and vaccine complacency, with the association strengthened at low levels of perceived risk. Perceived risk of contracting COVID also marginally moderated the relationship between disgust sensitivity and vaccine confidence, with the association strengthened at low and average levels of perceived risk.

Conclusions: Results suggest that individuals with elevated disgust sensitivity who also report low levels of perceived risk of contracting COVID are more likely to express vaccine hesitancy. Implications of these findings are discussed.
