Is this trial a fit for you?

Likely a good fit

Youth aged 16-24 with insomnia symptoms and sufficient English fluency who own a smartphone and can use health-related apps.

Probably not a fit

Participants with sleep disorders other than insomnia, uncontrolled psychiatric illness, or recent intensive psychotherapy for insomnia may experience limited benefit.

What this trial studies

This pilot randomized trial compares SleepFix, a digital brief behavioral therapy for insomnia delivered through a smartphone app with weekly e-psychologist calls, to a digital sleep-education control in youths aged 16-24 with insomnia symptoms. The study will assess feasibility metrics (recruitment, consent, randomization, engagement, and data completeness) and preliminary effects on insomnia severity, sleep diaries, sleep quality, fatigue, and mood. Outcome data and post-intervention interviews will inform the design of a larger, definitive trial. Insomnia in young people can impact mental health and daily functioning, and digital CBTi approaches may improve access to effective treatment.

Why it matters

Potential benefit: If successful, SleepFix could provide an accessible, scalable option to improve sleep and related symptoms in adolescents and young adults.

How similar studies have gone: Digital CBTi approaches have shown promise in adults; evidence in youth is limited but suggests potential feasibility and benefit for sleep symptoms.
