Objective To translate the King’s Brief Interstitial Lung Disease (K-BILD) to Chinese, so as to provide an well reliability and validity assessment instrument for health status of patients with interstitial lung disease.Methods Brislin’s transition model, six expert’s panel and pre-survey were used for initial Chinese version of K-BILD. Items analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), internal consistency reliability and test-retest reliability were used for validity and reliability test with 122 respondents.Results Ten-item Chinese version of K-BILD were proved to have great psychometric qualities, two factors were extracted by EFA, which could explain 63.35% of the total variance. Furthermore, the CFA demonstrates the fit indices of two-factors mode: χ2/df=0.797, RMSEA=0.000, NFI=0.848, IFI=1.048, CFI=1.000, TLI=1.071. Cronbach’s α and Guttman Split-half were 0.893 and 0.861, respectively. Besides, the test-retest reliability of the scale was 0.805.Conclusion The Chinese version of K-BILD scale has good validity and reliability, which is applicable for health status assessment in patient with interstitial lung disease.
