Study: Schoolwide phone bans show no significant impact on mental health

Commenters read the study’s results as showing no significant mental-health benefit from schoolwide phone bans, despite small estimates pointing toward worse depressive symptoms and well-being before statistical correction. Some argued this was predictable: students may already have had little phone access during class, bans can be weakly enforced, and most phone use happens outside school. One commenter noted that screen time appeared similar in the banned and permitted groups, suggesting the policy may not have changed the exposure at issue. Others questioned whether mental health was the right measure, proposing that bans could instead help grades, classroom behavior, or attention. Another saw the results as evidence that students were not worse off without phones.

Commenters differed over whether uncertain evidence should prevent bans. Some considered phones and their platforms harmful to learning, social connection, and communication, and favored restrictions even without demonstrated mental-health effects. Others saw phones as only a possible catalyst, with social division and the broader environment shaping young people’s well-being more fundamentally. The study’s interpretation also drew dispute: one commenter questioned possible conflicts of interest and research selection, while another criticized claims about uncontrolled supplements and seasonal darkness as unsupported explanations. That commenter highlighted the study’s lack of objective measures of in-school phone use; others argued that limited use before the bans was a likelier reason for the null findings.
