A cross-sectional study validates symptom measures for Crohn’s disease and ulcerative colitis, suggesting effective tools for clinical trials.

The research aims to validate the revised Symptoms and Impacts Questionnaire for assessing Crohn’s disease and ulcerative colitis.
Conducted a cross-sectional psychometric validation study with adults diagnosed with Crohn's disease or ulcerative colitis.
Participants completed the SIQ-CD or SIQ-UC measures for 14 days to evaluate psychometric properties.
Analyzed test-retest reliability and item correlations across different disease severity categories.
Revised SIQ measures demonstrated good understanding and relevance among participants.
Test-retest reliability showed interclass correlation coefficients >0.7 for most domains.
Overall domain consistency was strong (Cronbach’s alpha >0.70), indicating reliable measurement tools.

Hupé et al. (2026) studied this question.
