Causal Effects of Exposure to Social Media on Adolescent Mental Health

NIH-funded research Georgetown University · NIH-11135366

Researchers will follow 500 children aged 10–14 who are getting their first smartphone and compare mental health over three months between those with normal social media access and those whose phones block social media.

What this research studies

If your child is about to get their first smartphone, this study would enroll them and track their mood and behavior over time. Half of enrolled kids will use phones with no study-imposed social media limits and half will have social media access blocked for three months. The team will collect repeated reports of anxiety, depression, attention, and related behaviors to see how early social media exposure relates to changes in mental health. Results aim to show whether removing social media during this first-smartphone period changes emotional well-being and the underlying mechanisms.

Who could benefit from this research

Good fit: Ideal participants are 10–14-year-olds whose parents have decided to buy them their first smartphone and who are willing to follow the study procedures for three months.

Not a fit: Children outside the 10–14 age range, those already using smartphones extensively, or families unwilling to follow the phone restrictions likely would not benefit from or be eligible for this study.

Why it matters

Potential benefit: If successful, the results could give parents and clinicians clear guidance about whether limiting social media when kids first get smartphones reduces anxiety and depression.

How similar studies have performed: Most prior work is correlational and mixed, so this randomized, longitudinal field experiment is a novel approach to test causal effects.
