Description of intervention(s) / exposure
Other interventions - SleepFix mobile application

Experimental: Treatment - Participants will be instructed to use SleepFix mobile application for 3 weeks with an optional 3 weeks of additional therapy. Participants will complete daily sleep diary entries (which take less than 1 min) which are used to calculate the sleep window titration. SleepFix incorporates sleep restriction and stimulus control which have been shown to be the most powerful components of cognitive-behavioural therapy for insomnia - CBTi. It has been shown to produce rapid, clinically-meaningful insomnia symptom reduction in a shorter period of time compared with both face-to-face and digital CBTi. SleepFix does not require the user to complete modules and multiple components such as other digital CBTi programs (e.g. Sleepio). Further, it is personalised to the individual's current sleep patterns and requires minimal engagement compared to full CBTi.

No intervention: 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 3 modules provided bi-weekly and the information in these modules is presented as a subdomain through the study website. 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.


Other interventions: SleepFix mobile application
Digital behavioural therapy (dBTi) mobile application SleepFix® is specifically designed to treat insomnia and has been shown to be engaging and clinically efficacious.
