The Sleep Course: An Online Sleep Intervention for Adults With Self-reported Sleep Difficulties

This study evaluates an internet-delivered cognitive behavioural therapy for insomnia (ICBTi) intervention, known as the Sleep Course, within a routine online therapy clinic (the Online Therapy Unit). The Sleep Course will specifically be offered to clients with self-reported sleep difficulties (i.e., falling or staying asleep or waking early) and daytime distress and or impairment. This study aims to replicate the effectiveness and acceptability of the previously evaluated Sleep Course when delivered in Australia. The investigators will also assess uptake and completion rates within the clinic as well as demographic and clinical characteristics of individuals enrolled in the Sleep Course.
