Integrating health behavior theories to predict American's intention to receive a COVID-19 vaccine.
Haoran Chu, Sixiao Liu
PMID 33632632WHAT IT FOUND
Among US adults, intention to get a COVID-19 vaccine was higher with positive attitudes toward vaccines, perceived community benefit, fear, and believing others would get vaccinated.
Safety concerns were linked to lower intention. Susceptibility, severity, self-efficacy, and demographics were not linked.
Key findings
01The model predicted 82.1% of variation in intention to receive a COVID-19 vaccine.
02Intention was higher with positive attitudes toward vaccines, recent vaccination, believing others would get vaccinated, perceived community benefit, positive attitudes toward COVID-19 vaccines, and fear; it was lower with safety concerns.
03Self-efficacy and demographic variables did not show a significant association with intention.

What it does not show
The sample was recruited online, so it may not represent all US adults. The study measured intention, not actual vaccination. People who tested positive for COVID-19 or COVID-19 antibody were excluded, so results may not apply to those already infected. All measures were self-reported in one survey.
The easy way to misread this
Do not conclude that vaccine messaging based on these factors will increase actual vaccination. The study measured intention, not actual vaccination, and it did not test an intervention.
