Cross-Cultural Adaptation and Validation of the FRAIL Scale in Chinese Community-Dwelling Older Adults

Abstract Objective To cross-culturally adapt and test the FRAIL scale in Chinese community-dwelling older adults. Design Cross-sectional study. Methods The Chinese FRAIL scale was generated by translation and back-translation. An urban sample of 1235 Chinese community-dwelling older adults was enrolled to test its psychometric properties, including convergent validity, criterion validity, known-group divergent validity, internal consistency and test-retest reliability. Results The Chinese FRAIL scale achieved semantic, idiomatic, and experiential equivalence. The convergent validity was confirmed by statistically significant kappa coefficients (0.209-0.401, P P P Conclusions The Chinese FRAIL scale presents acceptable validity and reliability and can apply to Chinese community-dwelling older adults.
