Reliabilities of Discrepancy Scores and Supplemental Tables for the WASI–II

We analyzed data from the WASI–II manual to determine discrepancy score reliabilities of the Verbal Comprehension (VCI) and Perceptual Reasoning (PRI) indexes and the four subtests in the child and adult standardization samples. Reliabilities of the VCI–PRI discrepancy scores range from .78 to .86 for children and .82 to .89 for adults and generally are large enough to justify hypothesis generation. Discrepancy score reliabilities of the...
