Figures & data

Table 1. Weekly checkup questions

How are you finding the sessions?

How are you finding keeping the diary?

Have you made any changes suggested by the program? Does the weekly schedule suit you? How difficult are you finding it to keep up with the program (scale of 1–10)?

Table 2. Semi-structured interview topic guide

How did you find using the Sleepio program?

Was there anything you found particularly difficult?

Did you find it easier to use the phone or laptop/ why did you use the modality you used?

Were you able to remember all the different times asked for in the diaries? Did you find it difficult?

How motivated were you to stick with the program?

Do you feel like it helped? Have you noticed a change?

Did you learn anything new about the way we sleep?

What was your favorite thing about the program?

What was your least favorite thing?

Were any problems you found with the program related to your stroke, difficulty using the program/ difficulty remembering to complete the sessions?

Would you suggest anything to change within the program to make it better or easier to use?

Did you use all the functions: diary, checklist etc. if so, were they easy to use/ helpful? If not, why not?

Did you use the library articles or community?

Were you able to implement any of the changes?

Do you have anything else you would like to talk about that we touched on, or do you have any questions for me?
