Screen use not consistently linked to poorer psychosocial outcomes

Evaluating Psychosocial Development and Screen Use Across Age Groups

A secondary analysis of a large Scottish birth cohort evaluated cross-sectional associations between screen use and psychosocial development at 5, 10, and 15 years of age, alongside longitudinal associations from age 5 to later adolescence. Psychosocial development was measured using the Strengths and Difficulties Questionnaire (SDQ), analyzing total difficulties scores and prosocial scores.

The study found that daily screen use increased with age, while patterns varied by screen type. Cross-sectional analyses revealed no significant associations between screen use and total difficulties scores at 5 or 10 years of age. However, at 15 years of age, spending more than 5 hours per day on gaming showed a significant association with higher odds of above-average total difficulties scores compared to less than 1 hour per day. Conversely, utilizing social media and messaging for more than 1 hour per day was associated with lower odds of above-average total difficulties scores compared to spending under 1 hour per day.

Longitudinal Associations and Study Conclusions

In longitudinal evaluations, exceeding 5 hours of screen use per day at 5 years of age was linked to increased odds of above-average total difficulties scores at 10 years of age. This association did not persist at 15 years of age or within sensitivity analyses, and researchers noted no associations for the prosocial score.

Overall, study authors concluded that screen use was not consistently associated with poorer outcomes for children, suggesting that guidelines focusing exclusively on screen time may have limited impact on psychosocial outcomes.

Wider Context of Digital Exposure

Across the UK, digital device adoption is widespread, with data showing that 85% of children aged 3 to 5 years use screen-based devices to go online—a figure reaching 100% by age 10. Also, 81% of children aged 10 to 12 years utilize social media and messaging apps despite official age limits.

Researchers note that while widespread exposure continues to raise concerns among policymakers, researchers, and the media, previous evidence has often remained inconsistent due to heterogeneous methods, small sample sizes, and limited adjustment for confounders such as parent-child interaction.
