ICU护士多重耐药菌感染防控行为评估问卷的编制及信效度检验

Development of an Assessment tQuestionnaire on Multi-drugg Resistant Organism Infection Prevention and ControlBehaviorsamongICU Nurses and the test of its reliability and validity

目的为编制ICU护士多重耐药菌(multi-drugresistant organism,MDRO)感染防控行为评估问卷,并检验其信效度。方法依据COM-B(Capability,Opportunity,and Motivation-Behavior,COM-B)模型,通过文献回顾、小组讨论、德尔菲法、预调查形成初始问卷。于2023年10月一11月便利选取国内22所医院的285名ICU护士作为调查对象,进行信度和效度分析;于2024年2月便利选取国内28所医院的309名护士作为调查对象,进行验证性因子分析。结果ICU护士MDRO感染防控行为评估问卷包括能力、机会、动机和行为4个维度,共32个条目。问卷各条目的内容效度指数为0.833~1.000,平均内容效度指数为0.944。问卷Cronbach'sα系数为0.968,重测信度为0.812,折半信度为0.890;探索性因子分析4个因子方差贡献率依次为17.243%、14.464%、15.208%、22.663%,累计方差贡献率为69.578%:验证性因子分析各拟合指标在可接受范围内。结论ICU护士MDRO感染防控行为评估问卷具有较好的信效度,可作为ICU护士MDRO感染防控行为现状及其影响因素的评估工具。

Objective To develop assessment questionnaire on Multi-drug Resistant Organism(MDRO)Infection Prevention and Control(IPC)Behaviors among ICU Nurses,and to evaluate the reliability and validity.Methods We formed a pretest questionnaire by literature review,group discussion,expert consultation and pre-survey based on COM-B Model(Capability,Opportunity,and Motivation-Behavior Model).To analyze the reliability and validity of the questionnaire,we processed a survey among 285 ICU nurses in Intensive Care Unit of 22 hospitals in China from October to November 2023,participants were selected by convenience sampling.We processed a survey among 309 ICU nurses in Intensive Care Unit of 28 hospitals in China at February 2024,for confirmatory factor analysis.Results The assessment questionnaire on MDRO IPC behaviors among ICU nurses has 4 dimensions and 32 items.The content validity index(CVI)of each item in the questionnaire ranged from 0.833 to 1.000,with an average of 0.944.The total Cronbach'sαcoeficient,test-retest reliability and split-half reliability was 0.968,0.812,0.890,respectively.The exploratory factors analysis showed that the variance contribution rate of four factorswere 17.243%,14.464%,15.208%and 22.663%separately,and the cumulative variance contribution rate was 69.578%.All fitting indicators in confirmatory factor analysis were within an acceptable range.Conclusion The assessment questionnaire on MDRO IPC behaviors among ICU nurses has good reliability and validity,and can be used as a tool for assessing the current status and influencing factors of MDRO IPC behaviors among ICU nurses.
