School phone policies and their association with mental wellbeing, phone use, and social media use (SMART Schools): a cross-sectional observational study

Ongoing research is evaluating the impact of cellphone use on youth mental wellbeing and how school policies may reduce cellphone use or mitigate harmful effects. This research on UK school children finds no evidence that school policies restricting cellphone use reduces overall cellphone and social media use or creates better mental wellbeing.
