Women who are eligible and provide informed consent will be enrolled into this 2-armed, parallel group open label randomised controlled trial. Participants will be randomised 1:1 to receive dCBT-I (intervention arm) or to sleep hygiene education (control arm). The primary outcome will be the mean continuous change in sleep condition indicator (SCI) score in the intervention arm compared to the control arm at 6 months. In addition to this, the proportion of women with an SCI > 16 at 6 months will be assessed. Secondary outcomes will include fatigue, sleep related quality of life, depression, anxiety, as well as hot flush interference in those experiencing vasomotor symptoms.
This study will recruit women over the age of 18 with a current or prior cancer diagnosis who have clinical insomnia. This study will examine the efficacy of digital cognitive behavioural therapy for insomnia (dCBT-I) compared to sleep hygiene education.
