标准预防措施问卷的汉化与信效度检验

Translation and psychometric properties evaluation of the Chinese version of Standard Precautions Questionnaire

目的对英文版标准预防措施问卷(Standard Precautions Questionnaire,SPQ)进行汉化,并检验中文版SPQ的信效度。方法获取问卷使用授权后,对英文版SPQ进行翻译,经专家咨询、预调查后,形成中文版SPQ。于2021年12月—2022年3月,采用便利抽样法,对来自四川省3所三级甲等综合医院的609名护士进行问卷调查,并从中便利抽取30名调查对象,于其初次接受调查2周后,再次对其进行调查,以收集重测信度评价资料。结果中文版SPQ共包含7个维度、24个条目;条目水平的内容效度指数为0.750~1.000,问卷水平的平均内容效度指数为0.916。探索性因子分析共提取7个公因子,7个公因子的累计方差贡献率为80.784%,各条目在所属公因子上的载荷为0.770~0.904,各条目的因子归属情况与其在源问卷中的因子归属情况一致。验证性因子分析结果提示,模型配适度指标较好[χ2/df=1.470,渐进残差均方和平方根(RMSEA)=0.039,拟合优度指数(GFI)=0.963,调整后适配度指数(AGFI)=0.940,比较适配指数(CFI)=0.985,增值拟合指数(IFI)=0.985,非归准适配指数(TLI)=0.980,基准化适配度指数(NFI)=0.956]。问卷的Cronbach'sα系数为0.894,各维度的Cronbach'sα系数为0.836~0.950;问卷的重测信度系数为0.989,各维度的重测信度系数为0.900~0.989(P<0.05)。结论中文版SPQ具有良好的信效度,可作为评估护士遵守标准预防措施影响因素的工具。

Objective To translate the English version of the Standard Precautions Questionnaire(SPQ) into Chinese and analyze its reliability and validity. Methods After obtaining authorization to utilize the SPQ,the English version of the SPQ was translated and adapted culturally,and the Chinese version of the SPQ was formed after validity testing of the questionnaire content by experts,pretesting,and applicability evaluation. The Chinese version of the SPQ reliability and validity test was conducted from December 2021 to March 2022 using convenience sampling among a total of 609 clinical nursing staffs in three tertiary level A general hospitals in Sichuan Province. Results The Chinese version of the SPQ content validity index was 0.750-1.000 for each item level and 0.916 for the questionnaire. The exploratory factor analysis extracted a total of 7 factors,which were consistent with the original scale,and the cumulative variance contribution to the scale was 80.784%. The load value of each item on the common factor was 0.770-0.904. The Confirmatory factor analysis χ2/df=1.470,RMSEA=0.039,GFI=0.963,AGFI=0.940,CFI=0.985,IFI=0.985,TLI=0.980,NFI=0.956 with good model fit indicators. The Cronbach's α of the total questionnaire was 0.894,and the Cronbach's α of each dimension was distributed between 0.836-0.950. The test-retest reliablity coefficient of the questionnaire was 0.989. The intra-group correlation coefficient of the retest reliability of each dimension was well distributed between 0.900-0.989(P<0.05). Conclusion The Chinese version of SPQ has good reliability and validity. It can be used as an assessment instrument for nurses'compliance with standard precautions and impact factors.
