cognitive test performance and higher rates of Mild Cognitive Impairment in persons of non-English speaking background (NESB). This study examined differences in test performance between native English speakers and NESB on traditional and computerised neuropsychological measures; effects of demographic, linguistic and acculturation characteristics, and clinical and risk factors on performance, and whether these characteristics account for language group (English, NESB) performance differences. Methods: 873 native English speakers and 164 NESB proficient English speakers, aged 70-90 and dementia-free from the Sydney Memory and Ageing Study underwent comprehensive physical and medical history assessment and testing with 10 standardised neuropsychological (memory, verbal ability, processing speed, visuospatial, executive) tests and 5 computerised (reaction time, memory, executive) measures. Language group, demographics, linguistic, acculturation, medical and clinical variables were entered into multivariable linear regression models. Results:NESB participants were older and performed significantly worse on most tests, verbal and non-verbal. A larger difference between language groups was observed on a composite score of all neuropsychological measures (B1⁄4-0.66, p<.001) than a computerised test composite (B1⁄40.21, p1⁄4.001) after adjusting for age, education and sex. Multivariable regression analyses showed strongest effects of language group for Boston Naming Test (B1⁄4-.90 p<.001) and letter fluency (FAS) (B1⁄4.69 p<.001), followed by list learning and psychomotor speed; linguistic/acculturation factors (preferred language, main languages spoken, percent of day speaking English) influenced performance on naming and FAS, and medical variables (i.e. apolipoprotein 34 allele, history of stroke and depression score) were associated with memory and speed measures. No consistent reduction in effect of language group on performance was observed across tests when demographic, linguistic/acculturation and medical variables were included in the models. Conclusions:Performance differences were observed between native English speakers and NESB proficient English speakers on traditional and computerised cognitive tests, with stronger effects for verbal abilities. Linguistic and acculturation characteristics additionally contributed to verbal ability while medical risk factors influenced performance on select measures. Interestingly, none of the variables could account for the lower performance in NESBs hence further research is needed to investigate other potential explanatory factors.
