| Analysis Plan Title | Analyzing Behavioral and Attitudinal Correlates of COVID-19 Vaccination Status in Canada |
| Analysis Plan Description | The proposed research will investigate COVID-19 vaccine hesitancy during pregnancy across four countries—Italy, France, Ireland, and Canada. Despite well-established benefits of maternal immunization, uptake of COVID-19 vaccines among pregnant women remains suboptimal, influenced by unique behavioral, social, and contextual factors. This study aims to: (1) characterize This study will focus on data from a nationally representative Canadian sample (N = 18,032) collected across six survey waves between March 2021 and June 2022 through the polling firm Léger. Participants reported their vaccination status, categorized as fully vaccinated, partially vaccinated, or unvaccinated. They also indicated the frequency with which they engaged in seven specific preventive behaviors and their perceived importance of these measures, using predefined Likert-type scales. For analytical purposes, only responses indicating high adherence (“most of the time”) and strong perceived importance (“very important”) will be retained. Ambiguous or non-committal responses (e.g., “I don’t know” or “prefer not to answer”) will be treated as missing data. Descriptive statistics will be used to characterize the overall sample in terms of demographic, socioeconomic, and health-related variables. Pearson chi-square tests will be conducted to examine preliminary differences between the three vaccination groups. To further evaluate these associations, a series of multivariate logistic regression models will be conducted (one for each preventive behavior and attitude) as dependent variables, with vaccination status as the primary independent variable. Models will be adjusted for a comprehensive set of covariates. Odds ratios with 95% confidence intervals will be reported for each outcome, and statistical significance will be set at p < .05. |
