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

ObjectiveAccess 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.MethodA 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.ResultsRegression 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).ConclusionsThe 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.
