On September 28, 2026, JAMA Pediatrics published a large quantitative umbrella review examining associations between screen-based media use and developmental and mental health outcomes among children and adolescents.

    The researchers synthesized 23 meta-analyses representing 2,817,252 children from 64 countries. Greater screen-based media exposure was associated with lower overall academic achievement (r = −0.15) and poorer language skills (r = −0.14), as well as higher levels of internalizing and externalizing behaviors, emotional problems, and peer problems. Social media use was also associated with higher internalizing problems. JAMA Network

    However, significant associations were not found for executive functioning, prosociality, mathematics, science, or reading scores. Associations also varied according to factors including screen type and child age. Importantly, these findings describe associations and do not establish that screen exposure directly causes these developmental or mental health outcomes. JAMA Network

Comment from GAME-F

Evidence from nearly 2.8 million children reinforces the importance of considering digital media use as one potentially modifiable factor in child development and well-being.

    However, screen time alone does not tell us whether a child's digital use is problematic. Gaming, social media, learning, and video viewing are different experiences, and their meaning can vary according to age, context, and the individual child.

    The question should move beyond “How many hours?” toward “What is happening in the child’s life and development as a result of digital use?”

This perspective is closely aligned with GAME-F's emphasis on functional impact rather than duration of use alone.
