感染预防和控制护理缺失量表的汉化及信效度检验

Reliability and validity testing of the Chinese version of Missed Nursing Care in Infection Prevention and Control Survey

目的对英文版感染预防和控制护理缺失量表进行汉化,为评估护士在医院感染预防和控制活动上的缺失提供有效的测量工具。方法按照Brislin原则对英文版量表进行翻译,通过专家咨询和预试验进行跨文化调适后,并采用便利抽样法选取450名护士进行问卷调查。通过经典测量理论和项目反应理论的Rasch模型对问卷进行信效度检验。结果中文版感染预防和控制护理缺失量表由分量表B(31个条目,感控护理活动缺失的类型及频率)和分量表C(20个条目,感控护理缺失的原因)组成,分量表总的Cronbach′sα系数分别为0.973和0.902,重测信度分别为0.917和0.957,内容效度(S-CVI)分别为0.973和0.949。Rasch分析中残差主成分分析显示分量表B符合单维性,分量表C非单维性,其4个维度符合单维性;分量表B、C的项目信度分别为0.97和0.98,分离指数分别为5.27和7.20,样本信度分别为0.85和0.88,分离指数分别为2.42和2.73。结论中文版感控护理缺失量表信效度较好,可作为评估护士的感控护理缺失现状及分析缺失原因的测量工具。

Objective To translate the English version of the Missed Nursing Care in Infection Prevention and Control(MNCIPC)Survey into Chinese,and to provide an effective measurement tool for evaluating nurses′missed care in nosocomial infection prevention and control activities.Methods The English version of the scale was translated according to the Brislin principle.Cultural adjustment was performed through expert consultations and pre-tests,and 450 nurses were selected by convenient sampling me-thod to conduct a questionnaire survey.The reliability and validity of the questionnaire were tested based on classical test theory(CTT)and Rasch model of item response theory(IRT).Results The Chinese version MNCIPC Survey contains two subscales:subscale B(31 items,measuring types and frequency of missed care)and subscale C(20 items,measuring reasons for missed care).The Cronbach′sαcoefficient was 0.973 and 0.902,the test-retest reliability coefficient was 0.917 and 0.957,the scale-level content validity index(S-CVI)was 0.973 and 0.949,respectively for subscale B and C.Principal component analysis of residuals in Rasch model showed that the subscale B was unidimensional,and subscale C was non-unidimensional,though its four dimensions met the unidimensio-nal criteria.The item reliability coefficient was 0.97 and 0.98,and the separation index was 5.27 and 7.20 respectively for subscale B and C.The sample reliability coefficient was 0.85 and 0.88,and the separation index was 2.42 and 2.73 respectively for subscale B and C.Conclusion The Chinese version of the MNCIPC Survey has good reliability and validity,which can be used as a measurement tool to evaluate the current situation of missed nursing care and analyze the causes.
