Which Beliefs Predict Intention to Get Vaccinated against COVID-19? A Mixed-Methods Reasoned Action Approach Applied to Health Communication.
Additional Document Info
This research examined the underlying beliefs and psychological determinants of COVID-19 vaccination intention in order to inform effective health promotion efforts. We utilized the reasoned action framework in a mixed-methods, two-study approach. Study 1, an open-ended belief elicitation survey (N =197), explored the underlying beliefs associated with intention to get vaccinated against COVID-19 once a vaccine becomes available. In a quantitative survey with a representative sample of U.S. adults, study 2 (N =1656) tested the psychological determinants of intention to get vaccinated. Results revealed (1) the most common attitudinal, normative, and control beliefs about COVID-19 vaccination; (2) instrumental attitude as the strongest determinant of COVID-19 vaccination intention; and (3) 'achieving peace of mind' as an effective target for health promotion efforts. Further implications and directions are discussed.
