安宁疗护困难量表的汉化及信效度检验

Chinese version and reliability and validity test of the Palliative Care Difficulties Scale

目的:汉化安宁疗护困难量表(PCDS)并检验其信效度。方法:采用Brislin标准对PCDS进行正译、回译及文化调试,形成汉化版PCDS,便利抽取武汉市某高校两家附属三级甲等医院的473名肿瘤科护士进行量表信效度评价。结果:汉化版PCDS共15个条目。各条目与量表总分相关系数为0.637~0.838;量表Cronbach'sα为0.935,重测信度为0.969,折半信度为0.852;量表水平内容效度指数为0.93,条目水平内容效度指数为0.83~1.00,平均内容效度指数为0.99;探索性因子分析共提取4个公因子(知识缺乏、社区协调、多学科团队的沟通、与病人及家属的沟通),累计方差贡献率为84.370%,均有统计学意义(P<0.001)。结论:汉化版PCDS信效度良好,可作为评估我国医护工作者实施安宁疗护困难情况的有效工具。

Objective:To develop the Chinese version of the Palliative Care Difficulties Scale(PCDS)and test its reliability and validity.Methods:Translation,back translation,and cultural adjustment were performed based on the Brislin standard to develop the Chinese version of PCDS.A total of 473 oncology nurses from two affiliated tertiary grade⁃A hospitals of a university in Wuhan city were enrolled by convenience sampling method and conducted to evaluate the reliability and validity of the scale.Result:A total of 15 entries were composed in the Chinese version of PCDS.The correlation coefficient between each item and the scale's total score was 0.637⁃0.838;the Cronbach'sαwas 0.935,the test⁃retest reliability was 0.969,and the half⁃reliability was 0.852;the content validity index(CVI)of the scale was 0.93,the items CVI was 0.83⁃1.00,and the average CVI was 0.99.A total of 4 common factors(lack of knowledge,community coordination,multi⁃disciplinary team communication,communication with patients and families)were extracted by exploratory factor analysis,the cumulative variance contribution rate was 84.370%,and there was a statistically significant difference(P<0.001)in each of them.Conclusions:The Chinese version of PCDS has good reliability and validity,which could be an effective tool to evaluate the difficulty in implementing palliative care for medical workers in China.
