Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be given access to a six-week online mindfulness-based insomnia intervention, called A Mindful Way to Healthy Sleep, delivered at the website www.amindfulway.com.au. The program involves a series of video lessons and modules teaching formal and informal mindfulness skills, and the components of cognitive behavioural therapy for insomnia. The mindfulness skills include deep breathing, abdominal breathing, body scan, guided reflection, visualization, and structured meditation. The course is led by Dr Giselle Withers, a clinical psychologist with experience in sleep psychology, and mindfulness teacher. Each module takes 1.5-2 hours each week and builds on the knowledge and homework from the previous week. As part of the homework, they will be asked to complete 15-30 minutes of daily meditation using audio recordings, make behavioural and cognitive changes as instructed during the course.

Adherence will be reviewed through percentage of course completed and a self-report questionnaire at end of study.

Early detection / Screening
Comparator / control treatment
The control group will be given access to a six-week stepped-informational package regarding sleep health, hygiene and education via email. This will include informational text, diagrams and links to short videos. The initial component will cover psychoeducation around sleep, the science and evidence informing it and how it translates to sleep difficulty functionally. Building on this, participants will learn about ways to maintain basic sleep hygiene (e.g. monitor alcohol and caffeine intake, screen-time, light exposure etc.) to improve sleep habits. Finally, participants will be exposed to strategies around building a sustainable and healthy sleep routine, and receive further psychoeducation around links between sleep, ageing, mood and cognition. Thus, the emails will build on the information and activities done previously in each iteration.
After the 3-month follow-up, participants will be invited to the intervention arm, moving from an active control comparison to a waitlist-control methodology.

Statistical methods / analysis
A-priori power analyses powered at (f = 0.3) and ß = 0.90 revealed 106 participants will need to be recruited for adequate power after accounting for attrition. Linear mixed models will be used for statistical analysis. Initially, each model will include the treatment group (MBTi vs SHHE) as a between-subjects factor, time (pre, post, 3-months, 6-month follow-up, 12-month follow-up) as a within-subjects categorical factor and the group-time interaction as fixed effects and participants as the random effect. Later, random slopes may also be added to understand if there is a difference in participant sensitivity to the treatment group. This is because participants from the community with mild to clinical presentations of insomnia, depression and anxiety will be recruited. As a result of this heterogeneity, it can be hypothesised that there will be lesser sensitivity to treatment for individuals with highly comorbid and chronic presentations.
