Background The COVID-19 pandemic upended contexts for families; relatively little work has studied the influence of rapidly changing contexts on the mental health of parents. We aimed to assess the relation between financial strain and schooling modality with the mental health of adults living with school-age children across the pandemic.

Methods Using a large, national sample from the COVID-19 Trends and Impact Surveys (N=1 485 072 responses from November 2020 through June 2022), we used weighted multiple logistic regression with interactions for school semester to estimate changes in the association of frequent feelings of depression and anxiety, respectively, with financial strain and schooling modality, controlling for demographics and state, across time.

Results In all time periods, financial strain was associated with reporting frequent feelings of depression and anxiety, respectively. The association grew over time (p<0.001) from adjusted OR (aOR) 2.25 (95% CI 2.19, 2.32)/aOR 2.63 (95% CI 2.54, 2.73) in Autumn 2020 to aOR 3.11 (95% CI 3.01, 3.22)/aOR 3.79 (95% CI 3.64, 3.95) in Spring 2022. Living with children in fully online versus in-person schooling was associated with frequent feelings of anxiety and depression symptoms in all time periods, and increased from aOR 1.08 (1.05, 1.11)/aOR 1.06 (1.02, 1.10) in Autumn 2020 to aOR 1.20 (1.10, 1.32)/aOR 1.28 (1.16, 1.42) in Spring 2022.

Conclusion Associations between financial strain and online-only schooling with poor mental health increased during the COVID-19 pandemic. Policies to support parents in the face of external stressors, such as economic instability and school closures, may improve overall population mental health.
