目的 :构建临床护士不良事件风险感知量表,并进行信效度检验。方法 :通过半结构访谈与开放问卷调查形成量表初稿,然后经专家咨询及预调查进行修改。抽取917名泰安市二、三级医院临床护士进行信效度检验,对量表进行修改并形成终稿。结果 :总量表全部条目内容效度指数(CVI)为0.91,各条目CVI为0.71~1.00;利用项目分析和探索性因子分析最终确定20个条目、3个维度,分别为患者照护风险、系统流程风险和护士操作风险,累积方差贡献率为60.374%;验证性因子分析拟合总体较理想(χ2/df=2.427、GFI=0.936、AGFI=0.917、RMSEA=0.049、NFI=0.915、CFI=0.948、IFI=0.948);量表总体Cronbach’sα系数为0.939,各维度Cronbach’s?α系数均大于0.70;各条目与量表总分的相关系数为0.46~0.77(P<0.01)。结论 :临床护士不良事件风险感知量表体现出护理服务自身的特点,量表具有良好的信度和效度,可作为临床护士不良事件风险感知的测评工具。
Objective: To construct risk perception scale of clinical nurses adverse events and test the reliability and validity. Methods: Through the semi-structured interviews and open questionnaires to form the first draft, and then revised by expert advice and pre-investigation. A total of 917 clinical nurses from Grade II and Grade III hospitals in Tai’an City were selected to test the reliability and validity of the questionnaire, and the scales were revised and finalized. Results: The content validity index (CVI) of all the items in the total scale was 0.91, and the CVI of each item was 0.71-1.00. 20 items and 3 dimensions were finally determined by project analysis and exploratory factor analysis, which were the risk of patient care, Risk and nurse operation risk. The cumulative variance contribution rate was 60.374%. The confirmatory factor analysis fitted the overall ideal (χ2 / df = 2.427, GFI = 0.936, AGFI = 0.917, RMSEA = 0.049, NFI = 0.915, CFI = 0.948 , IFI = 0.948). The overall Cronbach’s α coefficient of the scale was 0.939, and the Cronbach’s α coefficient of each dimension was greater than 0.70. The correlation coefficient of each item and the total scale of the scale was 0.46-0.77 (P <0.01). Conclusion: The risk perception scale of clinical nurses’ adverse events reflects the characteristics of nursing service itself. The scale has good reliability and validity and can be used as a measuring tool of risk perception of adverse events in clinical nurses.
