SleepFix for Youth: Digital Behavioural Therapy for Insomnia With E-Psychologist Support
Sponsor: Woolcock Institute of Medical Research
Summary
This pilot randomised, open-label, parallel-group controlled trial will evaluate the feasibility, acceptability and effects of a psychologist-supported digital behavioural therapy for insomnia (dBTi) compared to a wait-listed active control (digital sleep health education) in young people aged 16-24 years with insomnia symptoms. The primary objectives are to evaluate the feasibility of conducting a full-scale trial by assessing recruitment, consent and randomisation rates, intervention uptake, and data completeness. Secondary objectives include exploring treatment effects on insomnia severity (Insomnia Severity Index), sleep diary metrics, sleep quality, fatigue, and mood (depression and anxiety symptoms). Post-intervention interviews will assess participant experience and acceptability. Results will inform the design of a larger randomised controlled trial.

SleepFix + e-psychologist support calls

There are four stages to the SleepFix app and participants will progress based on completion of each stage. Participants are required to enter sleep and bedtime/wake data into the smartphone app for baseline referencing and determination of sleep therapy. SleepFix uses an algorithm that calculates optimal sleep efficiency based on participants data
