Purpose: To characterize factors associated with parents' trust in messengers of COVID-19 guidance and determine whether trust in their doctors is associated with COVID-19 vaccination.
Design: Web-based and mailed survey (January-June 2022).
Setting: Maryland, USA.
Subjects: 567 parents/caregivers of public elementary and middle school students.
Measures: Parents rated trust in 9 messengers on a 4-point scale ["not at all" (0) to "a great deal" (3)], dichotomized into low (0-1) vs high (2-3). They reported on health insurance, income, race, ethnicity, education, sex, urbanicity, political affiliation, and COVID-19 vaccination.
Analysis: ANOVA and t-tests were computed to compare overall trust by parent characteristics. Multivariable logistic regression was run to evaluate factors associated with high trust for each messenger. Multivariable logistic regression was used to evaluate the relationship between trust in doctors and odds of COVID-19 vaccination.
Results: Most trusted messengers were doctors (M = 2.65), family members (M = 1.87), and schools (M = 1.81). Parents' trust varied by racial identity, sex, urbanicity, health insurance, and political affiliation. Greater trust in their or their child's doctor was associated with greater odds of child (aOR: 2.97; 95% CI: 1.10, 7.98) and parent (aOR: 3.30; 95% CI: 1.23, 1.47) vaccination.
Conclusion: Parent characteristics were associated with trust, and trust was linked to vaccination. Public health professionals should anticipate variability in trusted messengers to optimize uptake of public health guidance.
