SD: standard deviation
aWe defined “a participant having COVID-19 vaccination intent” as meeting one of the following two criteria; 1) pertaining to the question on how likely they were to get vaccinated for COVID-19, the participant responded “very likely” or “somewhat likely, 2) pertaining to the question on whether they planned to be vaccinated or not, the participant responded “yes” or “already vaccinated”.
bAverage of the three subscales.
cp-value was calculated using t test.
