Abstract

This study examines the relationship between children's screen time and ADHD symptoms, focusing on how this relationship may vary based on child-related factors (age and gender) and parent-related factors (parental aggravation, household income, and social support). Utilizing data from the National Survey of Children's Health (NSCH 2022; n = 25,104 U.S. children, ages 6–17), we found that increased screen time is linked to greater severity of ADHD symptoms. This relationship is particularly pronounced among younger children (ages 6–11), those whose caregivers report lower levels of parental aggravation, and children from higher-income households. In contrast, child gender and parental social support do not significantly affect this relationship. These findings highlight the need for targeted parental mediation to alleviate the negative impacts of screen time on vulnerable groups. Limitations of this study include issues related to causality, reliance on caregiver-reported measures, and limited data on the types and content of screen time. Overall, the findings provide valuable insights for parents, educators, and policymakers.
