Design outcomes

Primary

MeasureTime frame
The primary outcome Behavioral intent to uptake COVID-19 hygiene in the "next week". Behavioral intent will be measured using a list experiment in each of the three arms. We will analyze the binary endpoints of the list experiments using modified Poisson regression. Another primary outcome is knowledge of COVID-19 hygiene. We will measure knowledge using True/False items in the questionnaire. We will analyze the binary endpoints of the knowledge items using modified Poisson regression. As secondary analysis, we will repeat all of the analyses described above, controlling for baseline covariates (i.e., age, sex, and educational attainment). We will also measure bias between the intervention items that appear in the list experiments and as standalone items.
