Résumé	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 Simple Clinical Colitis Activity Index (SCCAI) is a practical, bedside tool for assessing disease activity in ulcerative colitis and colonic Crohn's disease. Published in 1998 by Walmsley and colleagues, the SCCAI condenses disease assessment into six items that can be administered in a office visit without laboratory or endoscopic data. It provides rapid, reproducible quantification of disease severity and is ideal for frequent monitoring in routine clinical practice.
