Performance discrepancies between the Children's Category Test (CCT) and the California Verbal Learning Test–Children's (CVLT–C) Version in the standardization sample

Abstract

Standardization data for the Children's Category Test (CCT) and California Verbal Learning Test–Children's Version (CVLT–C) were used to evaluate covariances and statistically significant discrepancies between the T scores of those instruments, as well as the base rate of specific discrepancies. The results indicate that the CCT and CVLT–C share only a limited amount of common variance and that statistically significant discrepancies between the respective T scores are actually quite common. It is suggested that evaluation of the potential clinical significance of a discrepancy between the obtained results of these two instruments in individual cases should include consideration of the presented base rates.
