a Variables that were significant in the univariate analyses (Table 2) were used as candidates in the forward stepwise models after adjusting for sociodemographic variables (sex, age, having a child < 6 years of age, job title).
Variables that were non-significant for all outcome variables, including training on COVID-19 and sending children to parents’ home to avoid infecting family members, are not included in this table.
Variables with p < 0.05 are in bold.
