A study by Toronto's Hospital for Sick Children and St. Michael's Hospital, published in JAMA, links early screen time to lower test scores. Researchers followed over 3,000 Ontario children from 2008 to 2023, tracking their screen time and comparing it to EQAO test results. Increased screen time before age eight was associated with lower reading and math scores in grades 3 and 6. Dr. Birken, the study's lead author, noted a 10% lower chance of meeting standards for each additional hour of screen use. The study encompassed various screen activities, lacking differentiation between educational and recreational content. Data collection relied on parental reports, which could introduce reporting bias. The authors emphasize that the findings demonstrate an association, not definitive causation. Child psychiatry researchers caution against using digital devices as a frequent calming mechanism for children. Excessive screen time might contribute to emotional and anger management difficulties later in life.
