The research question
Which nightly patterns accompany better or worse patient-reported function the following day?
Proposed design
Morning sleep diary plus brief daytime assessments, with a prespecified recall window and treatment-context questions.
Illustrative design: 4- to 8-week diary; setup and recruitment are scoped separately.
Data to collect
- Sleep onset, waking and estimated sleep duration
- Daytime sleepiness and energy
- Concentration and activity interference
- Reported sleep-treatment use
Planned outputs
- Night-to-day longitudinal records
- Sleep and functioning associations
- Assessment completion and burden summaries
What we confirm with you
We agree the population, sample size, country, collection tools, analysis plan and budget. Collection starts after the required consent, ethics or other permissions and a signed scope are in place.
- Verify sleep-questionnaire permissions
- Distinguish self-estimates from objective sleep measures
- Avoid diagnostic or causal claims from observational associations
Clinical records, laboratory results, photographs and device integrations are included only when access, collection quality and permitted use have been verified. Self-reported findings are identified as such.
