Informed by the social ecological model, which asserts that health behaviors and beliefs are the result of multiple levels of influence, we examined factors related to parents' support for in-school COVID-19 mitigation strategies. Using data from a survey of 567 parents/caregivers of public elementary and middle school students in eight Maryland counties, we employed regression models to examine relationships between parent-, child-, family-, school-, and community-level factors and acceptability of mitigation strategies. Acceptance of COVID-19 mitigation strategies was positively correlated with child- and family-level factors, including child racial identity (parents of Black children were more accepting than those of White children, odds ratio [OR]: 2.5, 95% confidence interval [CI] = [1.5, 4.1]), parent receipt of the COVID-19 vaccine (OR: 2.4, 95% CI = [1.5, 3.7]), and parent Democrat or Independent political affiliation (compared with Republican affiliation, OR: 4.2, 95% CI = [2.6, 6.7]; OR: 2.2, 95%CI = [1.3, 3.8], respectively). Acceptance was also positively associated with parents' perceptions of their school's mitigation approach, including higher school mitigation score, indicating more intensive mitigation policies (OR: 1.1, 95% CI = [1.0, 1.1]), better school communication about COVID-19 (OR: 1.7, 95% CI = [1.4, 1.9]) and better school capacity to address COVID-19 (OR: 1.9, 95% CI = [1.5, 2.4]). Community-level factors were not associated with acceptance. Child- and parent-level factors identified suggest potential groups for messaging regarding mitigation strategies. School-level factors may play an important role in parents' acceptance of in-school mitigation strategies. Schools' capacity to address public health threats may offer an underappreciated and modifiable setting for disseminating and reinforcing public health guidance.
