Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Cognitive-Behavioural Therapy for sleep and fatigue (CBT-SF): CBT-SF will consist of 8 one hour sessions conducted weekly either in-person or via tele-health using Zoom, focused on reducing and preventing sleep disturbance and fatigue. Sleep is addressed in sessions 1, 2, 5, 6 and 8 and fatigue in sessions 1, 2, 3, 4, 7 and 8. Session 1 will include psycho-education about post-stroke sleep disturbance and fatigue, including how poor sleep habits relate to fatigue. Self monitoring of daily activities and subjective fatigue levels will be initiated to encourage understanding of the link between activity levels and fatigue. Participants will be encouraged to engage in regular cardiovascular exercise as a form of behavioural activation. In session 2, the self-monitoring diary will be reviewed to encourage participants to regulate their activity schedule to balance rest and activity and sleep hygiene practices promoted. Traditional CBTi elements including stimulus control and sleep restriction are introduced, monitored through sleep diaries and reinforced in subsequent sessions. Sessions 3 and 4 will focus on gradually increasing or decreasing activity levels depending on goals. Cognitive therapy is used to address maladaptive thoughts underpinning behaviours that reinforce fatigue and disturbed sleep patterns. Session 5 will provide sleep education, including sleep need, sleep stages, circadian rhythms, homeostatic pressure, model of insomnia and include detailed discussion of sleep restriction, stimulus control and sleep hygiene recommendations and how these can be implemented for the participant. Adherence to new bedtime schedules and better sleep practices is reviewed at subsequent sessions. Cognitive interventions for insomnia (cognitive restructuring, imagery and visualisation) and behavioural interventions for insomnia (stimulus control, sleep restriction, constructive worry sheet and progressive muscle relaxation) will be addressed in Session 6. In Session 7 the focus will be on practical strategies to manage information overload and minimize physical and mental fatigue. The last session will promote long-term gains by reviewing therapeutic techniques, troubleshooting lingering concerns and establishing relapse prevention plans. The intervention has been manualized to ensure consistency of approach.
Participants will continue whatever medical, psychological or rehabilitative interventions they are otherwise receiving. The therapy will be individual and carried out face-to-face by Clinical Psychologists/Neuropsychologists with experience in CBT and understanding of stroke. They will be supervised by a psychologist expert in CBTi (Moira Junge). Treatment fidelity and adherence to protocol will be assessed by audio taping all sessions; a random sample of 10% of sessions will be rated by an independent assessor expert in CBT.

Comparator / control treatment
Health education control condition (HE): Controls will receive 8 weekly one-hour sessions providing education about brain injury, healthy lifestyle, sleep and fatigue. This will control for non-specific therapy factors and the focus on sleep and fatigue in the active intervention. Topics will include education about brain injury, fatigue, sleep, exercise, diet, alcohol, drugs, cognitive difficulties after stroke and recovery from stroke, with no guided practice or feedback. Activity pacing, sleep restriction and stimulus control principles will be strictly avoided.
Participants will continue whatever medical, psychological or rehabilitative interventions they are otherwise receiving. The therapy will be carried out by Clinical Psychologists/Neuropsychologists with understanding of stroke and the therapy will be manualised for consistency. It will be conducted face-to-face in the same number of individual sessions as the active treatment. Treatment fidelity and adherence to protocol will be assessed by audio taping all sessions; a random sample of 10% of sessions will be rated by an independent assessor.

They will be permitted to continue whatever medical, psychological or rehabilitative treatment they are receiving, including pharmacological treatment, other than benzodiazepines or hypnotics, provided that the treatment regimen/dose is stable and does not change throughout the study treatment period. The nature of any concurrent therapies will be documented.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization schedules will be generated by a statistician, independent of both the study and data analysis, who will notify the study co-ordinator of the participant’s treatment condition.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A stratified randomization will be adopted using a random length permuted blocks algorithm, {G, 2013 #61} 59 stratified according to median baseline sleep disturbance to ensure levels are matched across conditions. A 2:1 ratio will be used for CBT:Control.

Statistical methods / analysis
Regression methods appropriate for the analysis of repeated measures data, such as random effects / mixed-model regression or generalized estimating equations, 64,65 incorporating generalized models for non-normal data as needed, will be used to model PSQI scores as functions of treatment (CBT-SF vs control) and time point, controlling for baseline sleep disturbance and fatigue.
