What The Study Did: The average total daily screen use among a large, national sample of adolescents surveyed early in the pandemic was 7.7 hours a day, an amount higher than prepandemic estimates (3.8 hours/day) from the same group taken several years earlier, although younger age and slightly different screen time categories could account for differences.
