Factors Associated with Māori Performance on the WAIS-IV.

Neuropsychological tests are routinely used to assess Māori, the indigenous people of New Zealand, yet very few investigations of the psychometric properties of these tests with this population have been conducted. This paper focuses on factors that may impact performance of Māori adults on neuropsychological testing. The Wechsler Adult Intelligence Scale-IV (WAIS-IV) was administered to a sample of 284 Māori stratified for age (between 16 years and 90 years) and gender in order to establish a Māori normative data set.
