The Macquarie University Neuropsychological Normative Study (MUNNS): Australian Norms for the WAIS-R and WMS-R

Abstract

This paper reports on the conorming of the WAIS-R and WMS-R on a stratified random sample of 399 healthy young adults in the age range 18 to 34 years in Sydney, Australia. These data were collected as part of the Macquarie University Neuropsychological Normative Study (MUNNS). In deriving the norms, the influences of age, sex, and education were taken into account, and tables for deriving demographically adjusted scaled scores are provided. Tables for the IQ and memory index scores are provided, with values for the 90% and 95% confidence intervals bands around the predicted true scores. The confidence intervals for both test and retest conditions were derived using standard errors of estimation and prediction. Base-rate tables of both within-test and between-test differences are presented, as well as tables for predicting memory index scores from the IQ scores. A hypothetical set of data demonstrates the differences in results using the American norms versus the demographically adjusted Australian norms. Finally, a step-by-step example is presented to demonstrate the use of the MUNNS tables.
