Abstract

Internal consistency reliabilities for the Wechsler Abbreviated Scale of Intelligence (WASI; Wechsler, 1999) Verbal Scale IQ (VIQ)-Performance Scale IQ (PIQ) and subtest discrepancy scores are presented separately for the child and adult standardization samples. The reliabilities of the VIQ-PIQ discrepancy scores range from .78 to .87 for children and .81 to .91 for adults. The subtest discrepancy scores range from .59 to .81 for children and .67 to .85 for adults. Also provided are tables to (a) determine the significance between pairs of WASI subtest Tscores and (b) assist practitioners with ipsative strength and weakness determinations. Formulas are provided for practitioners who wish to generate additional tables when the situation requires a more precise analysis of a WASI profile.
