SMART Schools: Smartphones, social Media and Adolescent mental wellbeing: the impact of school policies Restricting dayTime use

1 in 7 adolescents (age 11-16) in the UK have a diagnosable mental health disorder. At the same time, most adolescents own a smartphone and many use social media.

Evidence suggests that smartphones and social media can be beneficial for mental wellbeing, but the benefits of smartphones and social media depend on how they are used.

This research aimed to establish which types of school phone policies are most supportive of pupil mental wellbeing.

What were the study's main activities?

  • This study took place in 30 secondary schools, with year 8 and year 10 pupils.
  • Researchers compared pupil mental wellbeing in schools that restrict phone use, with schools that permit phone use (e.g. allow phones to be used at breaks and lunchtimes).
  • Researchers measured behaviours associated with mental wellbeing, such as, physical activity, sleep, attainment and classroom behaviour.
  • To collect this data, pupils completed a 30 minute online survey and wore an activity monitor watch for 7 days.
  • The class teacher and a member of the senior leadership team completed a 30 minute online survey.
  • In some schools, 60 minute focus groups with pupils, school staff and parents/carers took place.
