| Analysis Plan Description | I will use the four waves of the representative Australian and Canadian datasets to assess participants’ adherence to COVID-19 preventative behaviours pre and post vaccinationMeasures: Participants’ sociodemographic characteristics (age, gender, income, and education), vaccination status, and perceived importance of COVID-19 preventative behaviors, self-reported adherence to preventative behaviors.Statistical Analysis Plan:1.Descriptive statistics will assess sample characteristics and number of participants responding to multiple survey waves2.Two-level mixed effects regression analyses with the country specified as the random effect will examine adherence to preventative health behaviours by vaccination status. Three-level mixed effects regression analyses with country and time specified as the random effect to account for clustering at different times will also be investigated.3.Secondary analyses will employ mixed-effects ordinal logistic regression to examine the separate behaviours comprising the composite score (above). Ordered logistic regressions will assess single-item outcomes. 4.Specification curves for each outcome variable will be conducted using the specr and rdfanalysis packages in R.5.Independent variables will be a range of socio-econ-demographic characteristics as well as perceived importance of prevention measures. Choice of independent variables will be informed by PCA and previous work on the Australian data. |
