About this trial
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

Treatments tested in this trial
App-based smartphone screen time restriction program
BehavioralTwo-week self-guided use of an iOS screen time restriction app. Participants block their most distracting apps, with notifications disabled. Unlocking requires a 30-second delay, allows 10 minutes of access, then a 5-minute cooldown.
Treatment groups
Trial outcomes
Primary outcomes
Symptoms of depression (PHQ-9)
Patient Health Questionnaire-9, range 0 to 27, higher scores indicate more depressive symptoms.
Secondary outcomes
Symptoms of anxiety (GAD-7)
Generalized Anxiety Disorder-7, range 0 to 21, higher scores indicate more anxiety symptoms.
Total smartphone screen time
Smartphone screen time by app category
Number of daily smartphone pickups
Other outcomes
Self-reported changes in daily functioning and well-being
Twelve single-item questions on perceived change over the past 2 weeks, each answered on a 5-point scale from 1 (much less than usual) to 5 (much more than usual). The domains are sleep, time spent with others, physical activity, time on other screens (computer, tablet), loneliness, satisfaction with oneself, rumination on negative thoughts, feeling of missing out, stress, ability to concentrate, satisfaction with own study effort, and getting done what one plans. Higher scores indicate more of the attribute than usual. Whether a higher score represents a better outcome depends on the domain.
Adherence to the screen time restriction tool
Self-reported proportion of the 2-week period with the blocking rule kept active, answered on a 5-level ordinal scale: all of the time, most of the time, part of the time, little of the time, none. Higher levels indicate greater adherence. Reported by the intervention group.
Perceived usefulness and burden of the tool
Perceived usefulness of the tool for reducing screen time and perceived burden in everyday life, each answered on a 5-point scale from 1 (not at all) to 5 (to a very great extent), and a single question on intention to continue use (yes, no, do not know). Higher usefulness indicates a better outcome and higher burden a worse outcome. Reported by the intervention group at 2 weeks and by both groups at 12 weeks.
