Crucial to the success of the COVID-19 vaccination campaign is the rate of people who adhere to it. This study aimed to investigate the reasons underlying people's willingness to get vaccinated in a sample of Italian adults, considering the effects of different individual characteristics and psychological variables upon positive vs. negative/hesitant vaccination intentions, as well as subjects' self-reported motivations for such intentions. An anonymous cross-sectional survey was distributed online in February 2021. The results showed that trust in science, number of vaccinations received in 2019, and belief that COVID-19 is more severe than the common flu, were associated with positive vaccination intentions. "Chance externality" health locus of control showed both direct and indirect effects upon positive vaccination intentions. Anxiety symptoms and participants' perceived psychological status also showed indirect positive effects. Subjects' self-reported motivations varied interestingly across positive vs. negative/hesitant intentions. Implications of these findings for identifying effective pro-vaccination messages are discussed in the final section of the paper.
