School smartphone policies and adolescent wellbeing
[READ IN FULL at source. NOT A STUDY: this is the journal's own linked commentary on the SMART Schools paper] Weiss, L., & Bonell, C. (2025). 'School smartphone policies and adolescent wellbeing.' The Lancet Regional Health - Europe, 51, 101237. doi:10.1016/j.lanepe.2025.101237. KEPT AND LABELLED AS COMMENTARY RATHER THAN DROPPED, because it is the source of the two limitations that must accompany every citation of the SMART Schools null: that the SCHOOL RESPONSE RATE WAS 10 PER CENT, and that the cross-sectional non-randomised design 'limits conclusions about causal effects'. It is the only item in this batch that was read in full at its published source, and it is a commentary rather than a study, so nothing in it establishes an effect of anything. Its function in the article is to stop a registered null being over-read in either direction.
