Study type
Description of intervention(s) / exposure
The intervention of interest for this study is the adjunctive internet based insomnia treatment program - Sleep Healthy Using the Internet (SHUTi). SHUTi is an efficacious e-health Cognitive Behavioural Therapy for Insomnia (CBTi), which consists of six modules delivered over nine weeks. These address sleep behaviours, sleep beliefs and sleep hygiene in a structured interactive format. Completion of the six modules involves up to an hour per week over nine weeks.

All trial participants will also have their depression managed over the three months of the trial by the psychiatric team using standard guideline based depression treatments.

Comparator / control treatment
Participants assigned to the adjunctive control treatment will interact with the specially designed internet-based attention-control program comprising credible, but ineffective, sleep health information. Participants in this treatment arm will be free to use the program at their discretion over the nine week period.

All trial participants will also have their depression managed over the three months of the trial by the psychiatric team using standard guideline based depression treatments.

Key exclusion criteria
We will exclude participants if: (a) they have a history of psychosis, or hypo/manic episodes; (b) have a current substance dependence; (c) have a score of <24 on the Mini Mental State Examination; all as determined by the psychiatrist clinical interview; (d) are a rotating shift worker with overnight shifts or transmeridian travel >2 hours in the past month with inadequate time to readjust prior to trial commencement; (e) have all the criteria for Restless Legs Syndrome as defined using the RLS-12 at screening; (f) are at high risk for obstructive sleep apnea (OSA) as defined by the Berlin Questionnaire or have been treated for OSA.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The trial will recruit men aged 50+ with current clinically significant depressive and insomnia symptoms from the BMRI Clinical Centre, local secondary and primary care providers, and potentially high yield community advertising (for example, Centrelink) and local newspapers. Participants will be automatically randomised upon completion of the online consent, eligibility screening, and baseline assessment phase. Allocation concealment will be achieved using a customised randomisation schedule. The fully itemised procedure allows for full replication and can accommodate stratification and specification of block sizes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised at the time of baseline assessment using a randomly generated number sequence allocated by a blinded researcher not involved in trial data gathering, assessments or treatment. Randomisation will be undertaken using permuted blocks and stratified by depressive symptom severity with strata defined by HAM-D scores of < 17 or >= 17.

Brief summary
This study investigates the efficacy of an internet-based insomnia treatment program (SHUTi), compared to an internet delivered control program, as an adjunctive treatment to beyondblue guideline based treatment for reducing depressive symptom severity amongst men aged 50 and over with co-morbid depression and insomnia symptoms.

Secondary aims are to determine whether adjunctive SHUTi improves insomnia and anxiety symptoms.
