A summary of results from a large-scale quantitative study examining the associations between frequency of video game, social media, and internet use at age 11 with depressive symptoms at age 14. It also explored the extent to which associations between screen time and depressive symptoms differed by gender. Data was used from the Millennium Cohort Study (MCS), a representative sample of 18,552 families and 18,818 children born in the UK between September 2000 and January 2002.
