美国创伤急诊评估工具的汉化及信效度检验

Sinicization and validation of emergency trauma assessment tools in the United States

目的分析汉化版美国通用创伤急诊评估工具(GETAC)在我国单中心运用的信效度。方法抽取北京积水潭医院2020年1月至6月153例急诊创伤患者,利用汉化版GETAC对患者进行回顾性分析。评价指标包括评定者信度、重测信度、内容效度、结构效度。信度分析采用Pearson相关性检验,效度分析采用探索性因子分析。结果GETAC的评定者间信度为0.900,重测信度Ⅰ级条目Pearson系数均值为0.818,总分Pearson相关性系数为0.881;Ⅱ级条目Pearson系数均值为0.954,总分Pearson系数为0.828。GETAC单个条目内容效度指数(I-CVI)为0.857~1.000,各个条目I-CVI均>0.780,总条目内容效度指数(S-CVI)为0.916。因子分析共提取8个公因子,累计贡献率为65.63%;各个条目在相应公因子上的因子负荷均>0.4。结论GETAC具有良好的信效度,可适用于我国创伤急诊早期对患者的评估。

Objective To analyze the reliability and validity of the Chinese version of generalized emergency trauma assessment criteria of America(GETAC)in single centers in China.Methods A total of 153 emergency trauma patients from Beijing Jishuitan Hospital from January to June 2020 were selected for retrospective analysis using the Chinese version of GETAC.The evaluation index includes evaluator reliability,retest reliability,content validity,and structure validity.Pearson correlation test was used for reliability analysis and exploratory factor analysis was used for validity analysis.Results The inter-rater reliability of GETAC was 0.900,the mean Pearson coefficient of GradeⅠretest reliability items was 0.818,and the total Pearson correlation coefficient was 0.881.The mean Pearson coefficient of GradeⅡitems was 0.954,and the total Pearson coefficient was 0.828.The single item content validity index(I-CVI)of GETAC was 0.857 to 1.000,the I-CVI of each item was>0.780,and the scale content validity index was 0.916.A total of eight common factors were extracted by factor analysis,and the cumulative contribution rate was 65.63%.The factor load of each item on the corresponding common factor was>0.4.Conclusion GETAC has good reliability and validity,which can be applied to the early evaluation of patients in trauma emergency department in China.
