State youth social media laws outpace evidence, George Mason study finds

A George Mason University-led study says states are moving fast on youth social media restrictions, but many laws rely on strategies with limited evidence for improving mental health. The findings, published in The Journal of Policy Practice and Research, aim to help lawmakers compare future proposals with the research base.

Why it matters: - State lawmakers are rushing to address concerns about youth mental health and social media use. - The new study suggests many of the most common policy choices may not be the ones best supported by evidence. - That gap could shape how states regulate platforms, schools and parents in the next round of bills.

What happened: - A research team led by Melissa Villodas of George Mason University analyzed 16 enacted laws across 10 states. - The study was published in The Journal of Policy Practice and Research. - The analysis offers one of the first frameworks for sorting and evaluating the growing patchwork of state social media laws. - The study covers the policy landscape through November 2024.

The details: - The laws fell into three broad categories. - The first category limits access through parental consent requirements, age verification, internet restrictions in schools and, in one case in Montana, an attempted TikTok ban. - This was the most common approach, even though evidence that these measures improve youth mental health is relatively limited. - The second category focuses on reducing harmful exposure. - Those laws restrict targeted advertising to minors, limit potentially addictive platform features and expand parental controls. - Existing research gives these approaches somewhat stronger, though still mixed, support. - The third category builds media literacy through instruction on misinformation, cyberbullying, online safety and social media’s effects on mental health. - Media literacy was the least common approach. - Existing evidence suggests media literacy may be promising, especially when it teaches both the risks and benefits of social media use. - In Florida, media literacy appeared in just one enacted law. - Villodas said the study uses a “person-in-environment” perspective that considers how policy and other outside forces shape a young person’s experiences and mental health. - Coauthors were Michael Wheeler and Natalia Acevedo of George Mason University, Fadi Hamati of Columbia Cornell Child and Adolescent Psychiatry at New York-Presbyterian, and Ishita Kapur of the University of Tennessee, Knoxville.

Between the lines: - The main disconnect is clear: the most widely used policy tool, limiting access, has the weakest evidence base. - Media literacy has drawn far less legislative attention, even though the study points to it as one of the more promising options. - The findings suggest states may be reacting faster than the research can confirm which interventions actually help.

What's next: - Villodas said the framework is meant to help policymakers judge future proposals as the evidence evolves. - As more states consider youth social media bills, the study could become a reference point for comparing restrictions with education-based approaches. - Reporters seeking comment on youth social media policies can contact Mary Cunningham at media contact.

The bottom line: - States are regulating youth social media aggressively, but the strongest legislative momentum is not always going to the strategies with the best scientific support.
