The research question
How does the timing and severity of bowel symptoms affect work, travel, sleep and social activity?
Proposed design
Condition-stratified prospective diary in adults reporting Crohn’s disease or ulcerative colitis, with clinical verification if required.
Illustrative design: 4- to 8-week diary; setup and recruitment are scoped separately.
Data to collect
- Urgency episodes and reported severity
- Bowel frequency and abdominal pain
- Fatigue and sleep disruption
- Work and activity interference
Planned outputs
- Daily symptom and burden profiles
- Urgency-related activity limitations
- Missingness and reporting-burden analysis
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.
- Keep Crohn’s disease and ulcerative colitis definitions explicit
- Obtain permission before using proprietary urgency instruments
- Clinical remission requires additional clinical evidence
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.
