Cross-cultural adaptation and validation of the Australian National University Alzheimer Disease Risk Index (ANU-ADRI) for Chinese community-dwelling residents: A cross-sectional Study

Objective To cross-culturally adapt the Australian National University Alzheimer Disease Risk Index (ANU-ADRI) and verify the reliability and validity of its cognitive activity domain. Methods According to Beaton's guidelines, the ANU-ADRI was were translated into Chinese. The psychometric properties of ANU-ADRI its cognitive activity was conducted among community-dwelling residents (n = 442) in Changchun, Harbin and Hegang from December 2021 to July 2023. Results The Chinese version of the ANU-ADRI had good content validity and face validity. Exploratory factor analysis of cognitive activity revealed a 3-factor structure, with a cumulative variance contribution rate of 64.124 %. Confirmatory factor analysis revealed a good model fit (x2/df = 1.664, RMSEA = 0.055, RMR = 0.090, GFI = 0.942, CFI = 0.919, IFI = 0.921, TLI = 0.902, and NFI = 0.824). The internal consistency (Cronbach's α = 0.807) and test-retest reliability (ICC = 0.787) were considered satisfactory. Conclusion The ANU-ADRI showed acceptable reliability and validity for assessing risk factors for Alzheimer's disease among middle-aged and elderly community-dwelling residents.
