Effects of Digital Detox on Mental Health in Young Adults: A Randomized Controlled Trial

14. september 2026 opdateret af: University of Bergen

The goal of this clinical trial is to learn whether a short, self-guided program for cutting down smartphone screen time can reduce symptoms of depression in young adults. It includes students in Oslo, Norway, who have applied for help at the student mental health service (SiO Mental Health).

The main questions it aims to answer are:

  • Does a 2-week screen time reduction program reduce symptoms of depression?
  • Does it reduce symptoms of anxiety?
  • Can a simple, widely available phone app reduce screen time, and does the reduction last?

Researchers will compare students who start the program right away with students who continue their usual care for 2 weeks and receive the same program afterwards. Participants are placed in one of the two groups by chance, like flipping a coin.

Participants will:

  • Answer questionnaires about depression and anxiety symptoms at the start and again after 2 weeks
  • Upload screenshots of the Screen Time summary on their iPhone at the start, after 2 weeks, and after 12 weeks
  • Install an app that blocks the apps they find most distracting and keep it active for 2 weeks, if they are placed in the program group
  • Take part entirely online, with no clinic visits and no contact with the study team

Eksperimentel: Screen time reduction
Adfærdsmæssigt: App-based smartphone screen time restriction program
