Discrepancy Score Reliabilities in the WAIS-IV Standardization Sample
Glass, Laura A.; Ryan, Joseph J.; Charter, Richard A.
Journal of Psychoeducational Assessment, v28 n3 p201-208 2010
In the present investigation, the authors provide internal consistency reliabilities for Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) subtest and Index discrepancy scores using the standardization sample as the data source. Reliabilities ranged from 0.55 to 0.88 for subtest discrepancy scores and 0.80 to 0.91 for Index discrepancy scores. Thus, the reliabilities of the WAIS-IV subtest discrepancy scores did not reach the greater than or equal to 0.90 criterion recommended for clinical decision-making, whereas four Index score coefficients reached this reliability standard. If the purpose is to generate hypotheses based on discrepancy scores, 23 of the 66 subtests and all of the Index reliabilities are greater than or equal to 0.80. (Contains 2 tables.)
