This is an open-label study and therefore both participants and nurses will be aware of allocation. The participant information sheet will inform participants that the study compares two different sleep intervention programmes but will not reveal the study hypothesis. Treatment providers (nurses) will not be involved in the collection of trial outcomes. Outcomes (questionnaires, diaries and actigraphy) are self-completed, remotely, by participants. It will be impractical to blind the research team however actigraph data will be scored by a sleep researcher blind to group allocation and the trial statisticians will remain blind to group allocation.
