The Greek Australian neuropsychological normative study: tests & norms for Greek Australians aged 70-85 years

Objective: Access to valid and reliable neuropsychological measures for use with culturally diverse groups in Australia is limited. The aim of this study was to adapt and translate a selection of English language neuropsychological tests, employ several existing standardised Greek language tests, and provide specific reference group normative data for Greek Australian older adults. Method: A convenience sample of 90 healthy older Greek Australians (M = 77.14 ± 4.46; range = 70–85), with a primary school level of education (M = 5.60 ± 0.68; Range = 4–6), was recruited throughout the Melbourne metropolitan area. Several neuropsychological measures were administered which assessed domains such as verbal and visual memory, confrontational naming, and executive functions. Results: Regression modelling revealed that age, education and sex predicted between 5% and 35% of the variance of test scores, with age being the most significant predictor of performance across a majority of measures. Therefore, the normative data for all tests were stratified according to three age bands (70–74, 75–79, 80–85). Conclusions: The use of culture-specific tests and norms for assessment of older Greek-Australians with limited education may facilitate accuracy of assessment findings, improve diagnostic outcomes, and reduce misclassification.
