中文版丹佛急诊创伤器官衰竭量表的信效度分析

A study on reliability and validity of Chinese version of the Denver Emergency Department Trauma Organ Failure Score

目的进行丹佛急诊创伤器官衰竭量表（Denver ED TOF）的汉化及其信度和效度评价。 方法对Denver ED TOF进行翻译、回译和文化调适，建立Denver ED TOF中文版；使用中文版Denver ED TOF便利抽取313例急诊创伤患者进行调查，评价量表的信度和效度。 结果因子分析量表共提取3个公因子，累计贡献率为63.327%，且各条目在相应的公因子上因子负荷值均〉0.4；量表的单条目内容效度指数为0.80~1.00，总条目内容效度指数为0.93；当量表评分≥2分时，量表的敏感度为84.0%，特异度为81.6%，量表的ROC曲线下面积为0.878（95%CI为0.812~0.944，P〈0.01）；整个量表的Cronbach α系数为0.738；评定者之间组内相关系数为0.994。 结论中文版Denver ED TOF具有较好的信度和效度，可应用于我国急诊临床工作中对创伤患者创伤后发生多器官功能衰竭风险预测的评定。

ObjectiveTo investigate Chinese version of the Denver Emergency Department Trauma Organ Failure Score and examine its reliability and validity. MethodsThe original Denver ED TOF Score was translated into Chinese and back translated and modified for cultural adaptation according to guidelines. A survey using Chinese version of the Denver ED TOF Score was conducted on 313 trauma patients in order to verify its reliability and validity. ResultsFactor analysis extracted three common factors, which explained 63.327% of variance of the total scale, and each item had high factor loading quantity （〉0.4）. The item-level content validity index of Chinese Denver ED TOF Score were 0.80 to 1.00. and the scale-level content validity index was 0.93. Its sensitivity was 84.0% and specificity was 81.6% when score of Chinese Denver ED TOF Score was two or more. The area under receiver operator characteristic curve for Chinese Denver ED TOF Score prediction of multiple organ failure was 0.878 （95% CI 0.812-0.944, P〈0.01）. The Chinese version of Denver ED TOF Score had higher internal consistency, with Cronbach Alpha coefficient 0.738 and intra-class correlation coefficients 0.994. ConclusionsThe Chinese version of Denver ED TOF Score has a high reliability and validity, which could be used as a tool for predicting and diagnosing development of MOF in adults following trauma.
