Description of intervention(s) / exposure
Intervention:
4-8, weekly or fortnightly, 60 minute sessions of individually administered CBT-Insomnia (mostly in person, but telehealth sessions will be provided if required) that will be augmented with the use of a clinical grade, at-home sleep monitoring device (Somfit - see below). Participants can attend sessions weekly or fortnightly depending on convenience and clinical need as discussed with the treating clinician.
Sessions will be held at two clinic urban locations in Perth, Western Australia: one university psychology training clinic, and one private behavioural sleep medicine clinic. Number of sessions will be determined by clinician's discretion of when appropriate CBT-Insomnia material has been delivered.
-Therapy will be administered by clinical psychologists and supervised clinical psychology trainees.
- number of sessions attended and dates of attendance will be recorded.
- within the Somfit-CBT-I software, clinicians can indicate key CBT-Insomnia strategies that they have covered in each session.
-Participation at the university trial site involves no cost to participants. Usual fees apply for participation at the private clinic.
-Participants will be asked to complete questionnaire assessment measures at baseline, post-treatment and 3-month follow-up. These will take approximately 30minutes and include sleep log, Insomnia Severity Index, Depression Anxiety Stress Scales, and the Fatigue Assessment Scale.
-Participants will be asked to wear the Somfit device for 5-7 nights at the above timepoints in order to gain an objective measurement of their sleep.
-clinicians and participants will decide together how frequently to wear the Somfit device during the CBT-Insomnia treatment.

SOMFIT
The Somfit device is not associated with any risk or harm. Somfit is a wearable, low voltage, battery operated device about the size of a 50c piece. Somfit collects signals such as EEG, heart rate, blood oxygen level, movement, body position, light, and noise. The Somfit device is attached to the participant's forehead through a self-adhesive and disposable skin electrode patch. Wearing the device may take a little getting used to, but most people adjust fairly quickly.
