ABSTRACT
Background: The COVID-19 pandemic has raised concerns about parent and child mental health, especially within disadvantaged families. However, little is known about how parental stress and loneliness during the pandemic influenced their children and no studies have investigated if these associations could vary by socioeconomic status. Methods: In July to September 2021, a large representative sample of parents (N = 4,524) in Québec (Canada) reported on aspects of their own mental health and that of their 9-10 year old child. Outcome variables were child externalizing and internalizing symptoms. Exposure variables were changes in parental loneliness and parental stress since the onset of the pandemic. The moderator variable was cumulative socioeconomic risk. Multiple linear regression analyses were executed and adjusted for confounding factors. Results: Child internalizing symptoms were associated with higher levels of parental stress (ß = 0.14, p<.001) and loneliness (ß = 0.23, p<.001). Child externalizing symptoms were also associated with parental stress (ß = 0.13, p<.001) and loneliness (ß = 0.18, p<.001). Most of these associations were stronger within the most disadvantaged households. Limitations: The cross-sectional design does not allow interpretations about causality. Conclusions: Increases in parental stress and loneliness since the onset of the COVID-19 pandemic would be detrimental to parent and child mental health. As these issues were amplified within families experiencing more socioeconomic adversities, our results can inform public policy to support families in times of crisis and direct resources to those most in need.
