Abstract
PURPOSE: To translate, cross-culturally adapt and validate the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF-C) to Chinese. METHOD: Forward and backward translations were conducted by two bilingual professional translators. Content validity was verified by a panel of a senior orthopaedic surgeon and six physiotherapists. The IKDC-SKF-C was tested on 84 patients. Psychometric testing included internal consistency (Cronbach's α) and test-retest reliability. Convergent validity used Spearman's correlation coefficient (rho) tests by comparing its score with the Chinese version of SF-36. RESULTS: The Internal consistency was excellent with Cronbach's α = 0.97. Test-retest reliability was supported with an ICC = 0.87. The IKDC-SKF-C was moderately related to concurrent measures of physical function and bodily pain (r = 0.64, p < 0.05). CONCLUSION: The translated Chinese IKDC-SKF is a reliable and valid tool with equal measurement properties and conceptual equivalent to the original version.
