The modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm) has been shown to be useful to assess and monitor patients in post-COVID-19 syndrome in developed countries. However, its reliability and validity in the Chinese population remains unclear.

To translate the C19-YRSm into a Chinese version (C19-YRSm-C), and test the reliability and validity of the Chinese version.

After obtaining the approval of the translation and use authority of the C19-YRSm from MANOJ SIVAN's team at the University of Leeds, United Kingdom, the research team translated the C19-YRSm and formed the C19-YRSm-C after translation, back-translation, and cross-cultural adaptation, according to the Translation and Cross-cultural Adaptation Procedure. From May 1 to 7, 2023, a simple random sampling method was used to select post COVID-19 patients from the "Wen Juan Xing" platform sample pool as the study subjects. The General Information Questionnaire and the C19-YRSm-C were used to survey them. 13 experts were invited to evaluate the content validity of the scale. The C19-YRSm-C was subjected to item analysis, reliability and validity analysis.

A total of 512 questionnaires were distributed and 370 valid questionnaires were recovered, with a valid recovery rate of 72.3%. The results of item analysis showed that the CR values of the items ranged from 6.589 to 22.725 (P<0.001), and the item-total correlation coefficients of the scale ranged from 0.460 to 0.815 (P<0.001). For reliability, the Cronbach's α coefficient, Guttman Split-half coefficient and test-retest reliability of the C19-YRSm-C was 0.881, 0.837 and 0.833, respectively. For content validity, the item-level content validity index (I-CVI) of the C19-YRSm-C ranged from 0.692 to 1.000, and the scale-level validity index (S-CVI) was 0.914. The results of confirmatory factor analysis (CFA) showed that the fitting indicators of the initial model were undesirable. After the establishment of a covariance correlation between error variables e12 and e13 according to the indication prompts, the fitting indicators of the modified model were within the acceptable range except for the adjusted goodness-of-fit index (AGFI). The results of discriminant validity analysis showed that the differences in scores for the 4 subscales of the C19-YRSm-C among post-COVID-19 patients with different chronic disease history and cumulative number of COVID-19 showed statistically significant differences (P<0.05). The differences were statistically significant when comparing the scores of the 3 subscales in addition to other symptoms before and after COVID-19 infection (P<0.05) .

The C19-YRSm-C has good reliability and validity, with good applicability in Chinese population, which can be used to assess and monitor the rehabilitation status of post COVID-19 patients in China.

约克郡新冠康复量表改良版（C19-YRSm）已在发达国家被证明可用于评估和监测新型冠状病毒感染后症状，但其在中国人群中应用的信效度尚不清楚。

汉化C19-YRSm，并对中文版C19-YRSm进行信效度检验。

研究团队在获得英国利兹大学MANOJ SIVAN团队的C19-YRSm汉化及使用授权后，参照翻译与跨文化调适流程对C19-YRSm进行汉化，经过翻译、回译、跨文化调适形成中文版C19-YRSm。于2023-05-01—07，通过简单随机抽样的方法抽取"问卷星"平台样本库中的新型冠状病毒感染康复者作为研究对象，使用一般资料调查表、中文版C19-YRSm进行调查，并邀请13位专家对量表进行内容效度评价。对中文版C19-YRSm进行条目分析、信度检验和效度检验。

共发放问卷512份，回收有效问卷370份，有效问卷回收率为72.3%。条目分析结果显示，各条目的｜CR值｜为6.589~22.725（P<0.001），与量表总分的｜r值｜为0.460~0.815（P<0.001）。信度方面，中文版C19-YRSm的Cronbach's α系数为0.881，Guttman折半系数为0.837，重测信度为0.833。内容效度方面，中文版C19-YRSm各条目的内容效度指数（I-CVI）为0.692~1.000，量表水平的内容效度指数（S-CVI）为0.914。验证性因子分析（CFA）结果显示，初始模型拟合结果不理想。根据提示增加误差变量e12和e13之间的相关关系后，除调整拟合优度指数（AGFI）外，修正模型的其余各项拟合指标均在可接受的范围内。判别效度分析结果显示，不同慢性病患病情况、累积感染次数调查对象中文版C19-YRSm 4个子量表得分比较，差异均有统计学意义（P<0.05）。新型冠状病毒感染前后除其他症状外的其他3个子量表得分比较，差异有统计学意义（P<0.05）。

中文版C19-YRSm具有良好的信度和效度，在中国人群中的适用性较好，可用于中国新型冠状病毒感染后患者康复状况的评估与监测。
