title: Base rates for the Selz-Reitan. Index of subtest scatter on the WPPSI-R.
abstract: Using the standardization sample of the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) an analysis was done to determine the base rates of occurrence of the Selz-Reitan Index (SRI) of unusual or abnormal scatter. Findings offered support for the use of the WPPSI-R to determine unusually or abnormally large SRIs in clinical practice. However, It was found that the clinical interpretation of obtained indexes depend upon the Full Scale IQ of the individual and the level of the SRI selected for interpretation. Further research on clinical neurological populations is encouraged.
