The COVID-19 pandemic presented unprecedented challenges to families in the form of social isolation, economic difficulties and inaccessibility of educational and supportive services. To assess the levels of parental stress and psychological distress among parents of school-age children during the COVID-19 pandemic and to analyse its correlation with spousal support. A cross-sectional, web-based study was conducted among the parents of school-age children in south India. One hundred thirty-two completed responses were obtained. Study tools included Parental Stress Scale, Spouse Support Scale and Kessler's psychological distress scale-6 item version. The mean parental stress score was 42.39 ± 9.679. Sixty percent of the participants reported moderate to high levels of psychological distress. Parental stress and psychological distress scores were noted to have a significant negative correlation with spousal support scores (r=-.486, p=.000 and r=-.401, p=.000 respectively). Our study findings show that the COVID-19 pandemic has taken a toll on the psychological well-being of parents of school-age children. Supportive interventions to address parenting difficulties need to be undertaken to prevent long-term adverse mental health outcomes. Lessons learnt from the pandemic are important for clinicians and policymakers to take measures to alleviate parental stress as well as to promote the psychological well-being of parents and children.
