护士用药能力评价量表的编制及信效度检验

Development and reliability and validity test of nurses′medication competence evaluation scale

目的编制护士用药能力评价量表并检验其信效度,为临床护士安全用药管理提供科学依据。方法基于质性访谈结果,结合角色理论、核心能力理论,通过文献分析和课题组讨论后形成量表初始条目池。通过专家函询、预调查,形成量表初稿。采用横断面调查方法,于2022年10—11月,采用便利抽样法选取大连市6所三级甲等医院825名临床护士进行问卷调查,检验量表的信效度。结果最终函询20名专家,年龄35~49岁。形成的护士用药能力评价量表包括药理学知识、药物管理能力、用药评估能力、用药医嘱核对及执行能力、临床实践能力、现代技术应用能力、教育咨询能力、沟通与协调能力、科研与学习能力、伦理法律实践能力、质量管理与风险管理能力11个维度,共50个条目。探索性因子分析确定11个公因子,累计解释86.525%的变异量。量表Cronbachα系数为0.975,量表各维度的Cronbachα系数为0.880~0.977,重测信度为0.703~0.875;量表的内容效度指数为0.99,各条目内容效度指数为0.83~1.00。量表总分及各维度得分与中国注册护士核心能力量表的相关系数分别为0.636~0.938。结论护士用药能力评价量表具有良好的信度和效度,可作为评价护士用药能力的有效工具。

Objective To develop and test the reliability and validity of the scale of nurses′medication competence.To provide scientific basis for the safe medication management of clinical nurses.Methods Based on the qualitative interview results,combined with role theory and core competence theory,the initial item pool of the scale was formed through literature analysis and discussion in the research group.The first draft of the scale was formed through expert correspondence and pre-investigation.Using the cross-sectional survey methed,from October to November 2022,a questionnaire survey was conducted among 825 clinical nurses from 6 tertiary hospitals in Dalian by convenience sampling method to test the reliability and validity of the scale.Results Totally 20 experts were consulted,aged 35-49 years old.The nurses′medication competence evaluation scale contained 11 dimensions,including pharmacological knowledge,medication management ability,medication evaluation ability,medication order checking and execution ability,clinical practice ability,modern technology application ability,educational consulting ability,communication and coordination ability,scientific research and learning ability,ethical and legal practice ability,quality management and risk management ability,with a total of 50 items.Exploratory factor analysis identified 11 common factors,which accounted for 86.525%of the variance.The Cronbachαcoefficient of the scale was 0.975,the Cronbachαcoefficient of all dimensions were 0.880-0.977,and the retest reliabilities were 0.721-0.875.The content validity index of the scale was 0.99,and the content validity index of all items were 0.83-1.00.The correlation coefficients between the scale and the Competency Inventory for Registered Nurse were 0.636-0.938.Conclusions The nurses′medication competence evaluation scale had good reliability and validity,and could be used as an effective tool to evaluate the medication ability of nurses.
