Answer

The Pediatric Crohn Disease Activity Index (PCDAI) was developed and validated in 1990. Its results are correlated with the physician’s global assessment and with the modified Harvey-Bradshaw index, and it has significant interobserver reliability. The important difference between this index and the Crohn Disease Activity Index (CDAI), which was developed for use in adults with Crohn disease, is the inclusion of growth parameters in the score.
