Brief Communication: INDEX, SUMMARY, AND SUBTEST DISCREPANCY SCORES ON THE WAIS-III IN POSTACUTE TRAUMATIC BRAIN INJURY PATIENTS

Abstract

WAIS-III profile interpretation typically involves the analysis of disparities between summary and subtest scores. Determination of clinically meaningful differences has been guided by published rates of discrepancies based upon the normative sample. However, noting that a particular profile discrepancy is uncommon among normals only represents one step in the interpretive process. Rates of such pairwise differences have yet to be published for clinical samples. In order to begin filling this void in the literature, we present frequencies of composite and subtest differences from a postacute traumatic brain injury sample. The practical utility of these tables, in conjunction with the normative tables, is demonstrated.
