This study conducted cross-cultural adaption for the Chinese version and verified its psychometric properties.Material and Methods: First, the Chinese Version of quick aphasia battery (CQAB) was adapted following WHO literature guidelines with steps of forward translation, expert panel, back-translation, pre-test, and interview, then develop the final version. Second, the psychometric properties tests were conducted in 128 post-stroke patients to identify if aphasia happens and verify the validity and reliability of CQAB.Results: The Cronbach’s alpha coefficient of the CQAB is 0.962, test–retest reliability 0.849, and inter-rater reliability 0.998. Content validity 0.917, KMO 0.861, exploratory factor analysis extracted 2 factors named “language understanding” and “language program”, cumulative variance contribution rate is 91.588% > 50%. Calibration association validity 0.977. Sensitivity 0.977, specificity 0.932, with the optimal cutoff point is 8.86.Conclusion: The study supported CQAB, which adapted following standardized guidelines, is reliable and effective to assess language impairment in post-stroke patients.Keywords: adaption, cross-cultural, post-stroke, reliability, validity
