- Conditions
- CancerInsomnia
- Interventions
- Other: Sleep Hygiene Education (SHE)Other: Digital Cognitive Behavioural Therapy for Insomnia (dCBT-I)
- Registration Number
- NCT05816460
- Lead Sponsor
- University College Dublin
- Brief Summary
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.
- Detailed Description
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.

Group Intervention Description Sleep Hygiene Education (SHE) Sleep Hygiene Education (SHE) The Sleep Hygiene Education (SHE) provided is based on recognised sleep hygiene advice and will consist of behavioural recommendations concerning lifestyle and environmental factors associated with sleep and insomnia. SHE will be delivered electronically. Digital Cognitive Behavioural Therapy for Insomnia (dCBT-I) Digital Cognitive Behavioural Therapy for Insomnia (dCBT-I) Digital Cognitive Behavioural Therapy for Insomnia (dCBT-I) will be provided on an online digital platform called Sleepio (BigHealth Ltd). Sleepio delivers fully automated CBT-I through 6 sessions, lasting an average of 20 minutes each, over the course of 6 weeks.
- Primary Outcome Measures
Name Time Method Proportion of women with SCI score >16 as measured by the Sleep Condition Indicator (SCI) Score 24 weeks The co-primary outcome will be the proportion of women with an SCI score \> 16 at 24 weeks. Possible total score ranges from 0 to 32, with higher values indicative of better sleep. A score of 16 or less is indicative of insomnia.
Mean continuous change in the intervention group compared to the control arm as measured by the Sleep Condition Indicator Score 24 weeks The primary outcome will be the mean continuous change in Sleep Condition Indicator score in the intervention arm compared to the control arm at 24 weeks. Possible total score ranges from 0 to 32, with higher values indicative of better sleep. The magnitude of change in SCI score that represents a reliable improvement on the Sleep Condition Indicator is 7 scale points
- Secondary Outcome Measures
Name Time Method Fatigue as measured by the Fatigue Symptom inventory (FSI) 12, 24 and 33 weeks The Fatigue Symptom inventory (FSI) is a method of evaluating the impact of fatigue in people with cancer. The scale is composed of 14 items and is designed to evaluate multiple aspects of fatigue, including its perceived severity, frequency, and interference with daily functioning. Items use an 11-point, likert-type scale that ranges from one fatigue-related extreme to another (lower points on the scale denote less acute problems with fatigue. A score of zero denotes no interference, whilst a score of 10 indicated extreme interference). A global score can be obtained for items 1-13.
Sleep related Quality of life as measured by Glasgow Sleep Impact Index (GSII) 12, 24 and 33 weeks The Glasgow Sleep Impact Index (GSII) is a self report measure which asks patients to generate and assess three domains of impairment unique to their own experience. The three generated areas of impairment are ranked in order of concern on a scale of 1-3, with 1 being the most concerning impairment. Each impairment is then rated on a visual analogue scale with respect to impact in the last two weeks.
The impact of Hot Flushes as measured by the Hot Flash Related Daily Interference Scale (HFRDIS) 12, 24 and 33 weeks The Hot Flushes as measured by the Hot Flash Related Daily Interference Scale is a tool for assessing the impact of hot flushes on quality of life. The scale measures the impact of hot flashes on overall Quality of life, as well as on 9 specific activities (work, social activities, leisure activities, sleep, mood, concentration, relations with others, sexuality, enjoyment of life). The scale consists of a series of 0-10-point numeric rating scales. A score of zero reflects no interference and a score of 10 denotes complete interference. Total score can range from 0-100.
Anxiety as measured by the Generalised Anxiety Disorder - 7 (GAD7) questionnaire 12, 24 and 33 weeks The Generalised Anxiety Disorder - 7 (GAD7) is a 7 item questionnaire used to screen for generalised anxiety disorder. Each of the 7 items can be allocated a score of 0-3. Total score can range from 0-21. A score of more than 10 indicated a high likelihood of significant anxiety.
Depression as measured by the Patient Health Questionnaire - 8 (PHQ8) 12, 24 and 33 weeks The Patient Health Questionnaire - 8 (PHQ8) is an 8 item questionnaire used for the diagnosis of depression. Each of the 8 items are allocated a score of 0-3. Scores can range from 0-24. A score of more than 10 indicates a high likelihood of clinical depression. Scores of more than 20 are indicative of severe disease.
