Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a mobile-phone application called "Sleep Ninja" which is based on Cognitive Behavioural Therapy (CBT) for Insomnia, and has been designed to help young people with sleep disturbances. The intervention has been gamified such that user completes six training sessions, which teach them strategies to assist with healthy sleep patterns. The material that is covered includes: psychoeducation, stimulus control, emphasis on regularity in sleep-wake cycles, sleep hygiene, behavioural activation to encourage night-time sleepiness and sleep-focused cognitive therapy. Each training session goes for 5-10 minutes and needs to be completed once in every 3-7 days in order for the user to progress to more challenging levels. This core learning component is supplemented by homework exercise that involve tracking sleep via use of an electronic sleep diary. The app also sends reminders to the user about when they should commence their wind-down routine before bed, provides a weekly update on their progress, includes a wide range of helpful sleep tips as well as a bedtime meditation recording. Sleep Ninja is fully-automated and is used independently by young people for 3-6 weeks.
