This study evaluates the efficacy of digital cognitive behavioural therapy for insomnia (Sleepio) in chronic stroke survivors. Half of the participants will receive access to the digital (online) programme, half will receive a leaflet with sleep hygiene information. The primary outcome will be changes in sleep quality, assessed as the score on the Sleep Condition Indicator.
Stroke is one of the leading causes of adult disability. Many stroke survivors report difficulties with sleep and our current research confirms this, indicating that chronic community dwelling stroke survivors experience poorer self-reported and objective sleep quality than age matched healthy controls. "Sleepio" is an online Cognitive Behavioural Therapy for Insomnia (CBT-I) programme. The efficacy of this intervention has been demonstrated in people with chronic insomnia but has not yet been tested in people with stroke. The study therefore aims to determine whether digital CBT-I is effective for improving sleep quality in chronic stroke survivors. Participants will be randomised to receive either digital (online) CBT-I or a leaflet with sleep hygiene information. The primary outcome is the change in self-reported sleep quality, assessed using the Sleep Condition Indicator. Secondary outcomes include changes in sleep fragmentation and wake after sleep onset assessed with actigraphy, self-reported sleep onset latency from the sleep diaries, anxiety and depression using the PHQ9 and GAD7, quality of life using the SIS-8 and EQ-5D-5L as well as changes in healthcare costs during the 8 week follow up.

Sleep Condition Indicator Score at Post-intervention, Adjusted for Baseline Score and Sex
Self-reported sleep quality questionnaire, range 0-32, higher numbers indicate better sleep quality Assessed at baseline and post-intervention. Outcome is post-intervention score after adjustment for baseline score and sex using Analysis of Covariance
Time frame: 8 weeks
Sleep Condition Indicator Score at 8 Week Follow up Adjusted for Baseline Score
Self-reported sleep quality questionnaire, range 0-32, higher scores indicate better sleep quality. Assessed at baseline and 8 week follow up. Outcome is follow up score after adjustment for baseline score using Analysis of Covariance.
Time frame: 16 weeks
Sleep Fragmentation, Assessed at Post-intervention Adjusted for Baseline
Sleep fragmentation assessed using actigraphy. Higher values indicate more disrupted (worse) sleep. The minimum value is 0. There is no specified maximum value. According to the manual for the software which does the calculation the definition of sleep fragmentation index is "the sum of the Mobile time (%)' and the 'Immobile bouts \<=1min (%)".There are no units associated with sleep fragmentation. The values are never presented in the literature or elsewhere as a percentage and therefore they are not presented as a percentage here. Assessed at baseline and post-intervention. Outcome is post-intervention score after adjustment for baseline score using Analysis of Covariance.
Time frame: 8 weeks
Sleep Fragmentation at 8 Week Follow up Adjusted for Baseline
Sleep fragmentation assessed using actigraphy. Higher values indicate more disrupted (worse) sleep. The minimum value is 0. There is no specified maximum value. According to the manual for the software that does the calculation, the definition of sleep fragmentation index is "the sum of the Mobile time (%)' and the 'Immobile bouts \<=1min (%)".There are no units associated with sleep fragmentation. The values are never presented in the literature or elsewhere as a percentage and therefore they are not presented as a percentage here. Assessed at baseline and 8 week follow up. Outcome is follow up score after adjustment for baseline score using Analysis of Covariance

Wake After Sleep Onset at Post-intervention Adjusted for Baseline
Wake after sleep onset assessed using actigraphy, higher values (minutes) indicate more disrupted sleep. Assessed at baseline and post-intervention. Outcome is post-intervention score after adjustment for baseline score using Analysis of Covariance
Time frame: 8 weeks
Wake After Sleep Onset at 8 Week Follow up Adjusted for Baseline
Wake after sleep onset assessed using actigraphy, higher values (minutes) indicate more disrupted sleep. Assessed at baseline and 8 week follow up. Outcome is follow up score after adjustment for baseline score using Analysis of Covariance.
Time frame: 16 weeks
Change in Sleep Onset Latency
Sleep onset latency assessed using online sleep diary, higher values indicate poorer sleep quality
Time frame: 8 weeks
Self-reported Depression Post-intervention, Assessed as PHQ9 Score at Post-intervention Adjusted for Baseline
PHQ9 score, range 0-20, higher values indicate more depressive symptoms. Assessed at baseline and post-intervention. Outcome is post-intervention score after adjustment for baseline score using Analysis of Covariance
Time frame: 8 weeks
Self-reported Depression at 8 Week Follow up, Assessed as PHQ9 Score at 8 Week Follow up Adjusted for Baseline
PHQ9 score, range 0-20, higher values indicate more depressive symptoms. Assessed at baseline and 8 week follow up. Outcome is follow up score after adjustment for baseline score using Analysis of Covariance
Time frame: 16 weeks
Self-reported Anxiety at Post-intervention, Assessed as GAD7 Score Post-intervention Adjusted for Baseline
GAD7 score, range 0-21, higher values indicate more anxiety symptoms. Assessed at baseline and post-intervention. Outcome is post-intervention score after adjustment for baseline score using Analysis of Covariance
Time frame: 8 weeks
Self-reported Anxiety at 8 Week Follow up, Assessed as GAD7 Score at 8 Week Follow up Adjusted for Baseline
GAD7 score, range 0-21, higher values indicate more anxiety symptoms. Assessed at baseline and 8 week follow up. Outcome is follow up score after adjustment for baseline score using Analysis of Covariance
Time frame: 16 weeks
Stroke Specific Quality of Life, Assessed as SIS Index Post-intervention Adjusted for Baseline
SIS-8 index, range 0-100, higher values less impact of stroke on quality of life. Assessed at baseline and post-interventin. Outcome is post-intervention score after adjustment for baseline score using Analysis of Covariance
Time frame: 8 weeks
Stroke Specific Quality of Life at 8 Week Follow up, Assessed as SIS Index at 8 Week Follow up Adjusted for Baseline
SIS-8 index, range 0-100, higher values indicate less impact of stroke on quality of life. Assessed at baseline and 8 week follow up. Outcome is follow up score after adjustment for baseline score using Analysis of Covariance
