Behaviour - SleepFix mobile application
Behaviour - Sleep Health Education

Experimental: Digital brief behavioural therapy for insomnia - Participants randomised to the digital brief behavioural therapy for insomnia (SleepFix app) will be provided an unique access code to download the app. The intervention uses sleep retraining therapy to reduce excess time spent in bed and retrain sleep by matching time in bed (minimum of five and a half hours) to total sleep time. All participants in the intervention arm will also be provided a sleep-tracking wearable device (Fitbit) which will synchronised bed times (going to bed and rising) and are synchronised with the SleepFix app. Participants wil complete a daily sleep diary, rate sleep quality and mood. The intervention is provided for 6 weeks.

Active Comparator: Sleep Health Education wait-list control - Participants randomised to the control group will gain access to the first Sleep Health Education module immediately following completion of baseline questionnaires. There are three modules provided bi-weekly with information about sleep health and broad details about managing sleep disturbances. Participants will receive a link to this information as each module is made available.
Upon completion of the study (week 26), the control group will receive free access to the SleepFix mobile application.


Behaviour: SleepFix mobile application
The SleepFix app is a novel, innovative way to deliver digital brief behavioural therapy for insomnia for adults.

Behaviour: Sleep Health Education
These internet-based modules provide an active control intervention consisting of 3 modules provided bi-weekly. The participant will receive a link to this information as each module is made available. Control participants will have full access to these modules for the duration of the study. They reflect basic educational information regarding sleep health for poor sleepers that is otherwise easily accessible on the internet.
