摘要	The Crohn's Disease Activity Index (CDAI) is a comprehensive, weighted index for assessing disease activity in Crohn's disease. Developed in 1976 by Best and colleagues for the National Cooperative Crohn's Disease Study, the CDAI integrates eight clinical and laboratory variables into a single score ranging from <150 (remission) to >450 (severe activity). Although more complex than symptom-based tools, the CDAI captures the multidimensional nature of Crohn's disease and remains the reference standard for severe disease assessment.	The Short Inflammatory Bowel Disease Questionnaire (IBDQ-32) is a validated patient-reported outcome measure designed to assess the impact of inflammatory bowel disease (IBD)—both ulcerative colitis and Crohn's disease—on health-related quality of life. Derived from the original 32-item IBDQ, this instrument comprises four domains: Bowel Symptoms, Systemic Symptoms, Social Function, and Emotional Function. The IBDQ-32 is responsive to treatment and is increasingly used in IBD clinical trials and practice.
