Description

This self report health status scale can be used for patietns with ulcerative colitis or crohn’s disease. It was developed from a large database of 991 patients belonging to the Crohn’s and Colitis Foundation. The items were derived from factor analysis of symptoms and health status measures. Validation of the items were achieved through strong correlations with general well being, health status and pain as independent measures. By design, this questionnaire was a better predictor of health status than the CDAI.
