Abstract：
Spinal Cord Independence Measure (SCIM) was an important functional outcome measure specifically designed for spinal cord injury (SCI) patients, with the self-reported version of SCIM (SCIM-SR) published in 2013. This study aims to translate the SCIM-SR into Chinese, and to investigate the validity of Chinese SCIM-SR among SCI patients. This Chinese version of SCIM-SR was translated into Chinese in a standardized approach, and then filled out by a sample of patients with SCI (n = 205) within 3 days after admission. Validity of Chinese SCIM-SR was then analyzed using Rasch analysis and principal component analysis. The subscale Selfcare and subscale Mobility showed good fit to the Rasch model, with no significance found in Chi-square test results for item-trait interaction, using Bonferroni adjustment for the significant level (χ2 =18.125, P = 0.111; χ2 =33.629, P = 0.006). Mean fit residual for items and persons of each subscale were within ± 2.5. The model fit of the subscale of Respiration and Sphincter Management was not satisfactory even after deleting one item and merging two items with local dependence. However, Kaiser-Meyer-Olkin test was > 0.50 in total score and all the subscales of Chinese SCIM-SR, and P < 0.05 in the Bartlett\'s test. There was no differential item functioning for gender, time post injury, age, and etiology in any of the three subscales. An online version of Chinese SCIM-SR was also developed. It is concluded that the SCIM-SR in Chinese is valid for application in individuals with SCI. SCIM-SR is considered as an important tool for self-reporting functional status from SCI individuals\' perspective.
摘要：
脊髓独立性测量（SCIM）是一种专门为脊髓损伤（SCI）患者设计的重要功能结果测量，自报告版本的SCIM（SCIM-SR）于2013年发布。本研究旨在将SCIM-SR翻译成中文，并探讨中国人SCIM-SR在SCI患者中的效度。SCIM-SR的中文版以标准化的方式翻译成中文，然后在入院后3天内填写SCI患者样本（n=205）。然后使用Rasch分析和主成分分析对中文SCIM-SR的有效性进行分析。子量表自我护理和子量表移动性显示出与Rasch模型的良好拟合，在项目-性状相互作用的卡方检验结果中没有发现显著性，采用Bonferroni校正为显著性水平(χ2=18.125,P=0.111;χ2=33.629,P=0.006)。每个子量表的项目和人员的平均拟合残差在±2.5以内。即使在删除一个项目并合并具有局部依赖性的两个项目之后，呼吸和括约肌管理子量表的模型拟合也不令人满意。然而,Kaiser-Meyer-Olkin检验的总分和中国SCIM-SR的所有分量表均>0.50，Bartlett检验P<0.05。没有性别差异项目的功能，受伤后的时间，年龄,和病因在三个分量表中的任何一个。还开发了中国SCIM-SR的在线版本。结论是，中文SCIM-SR适用于SCI患者。从SCI个人的角度来看，SCIM-SR被认为是自我报告功能状态的重要工具。
