To translate, cross-culturally adapt and validate the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF-C) to Chinese.
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.
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).
The translated Chinese IKDC-SKF is a reliable and valid tool with equal measurement properties and conceptual equivalent to the original version.
将国际膝关节文献委员会主观膝关节评分表（IKDC-SKF-C）翻译并跨文化适应为中文。
由两名双语专业翻译进行前后翻译。内容效度由一名资深骨科医生和六名物理治疗师组成的专家组进行验证。84 名患者接受了 IKDC-SKF-C 的测试。心理测量学测试包括内部一致性（Cronbach's α）和重测信度。通过比较其与中文版 SF-36 的得分，采用 Spearman 相关系数（rho）检验来评估其与其他指标的相关性。
Cronbach's α 为 0.97，内部一致性极好。ICC 为 0.87，重测信度可靠。IKDC-SKF-C 与身体功能和躯体疼痛的同期指标中度相关（r = 0.64，p < 0.05）。
翻译后的中文 IKDC-SKF 是一种可靠且有效的工具，其测量属性与原始版本相同，具有概念等效性。
