| Analysis Plan Title | Influence of COVID-19 vaccine motivators on vaccine intention: a comparative assessment of individuals with and without cardiovascular diseases |
| Analysis Plan Description | The analysis will draw on survey data collected between 2020 and 2022, encompassing responses from waves 2 to 8. Cardiovascular disease (moderator variable) is operationalized as any disorder affecting the heart or blood vessels. COVID-19 vaccine intention (dependent variable) is operationalized as the likelihood of getting the vaccine, and COVID-19 vaccine motivators (independent variables) are government-initiated measures to modify behaviours towards receiving the vaccine. These study variables include two, one, and six items from the iCARE survey, respectively. Chi-square test will be used to assess bivariate relationships between vaccine intention and vaccine motivators and to determine differences by sex and between participants with and without CVD. We will use logistic regression analysis to determine which motivators are predictors of vaccine intention in males and females, as well as people with CVD versus those without. In all analyses, the independent variables will include participant sociodemographic variables such as age, educational level, household income, residence, and COVID-19 vaccine motivators. In the regression analysis, adjustments will be made for sociodemographic variables like age, educational level, household income, and residence. Interaction terms will be applied in the regression analysis to assess the relationship between vaccine motivators and vaccine intention by disease status. In all statistical analyses, the significance level will be set at 0.05. |
