消毒供应中心护士岗位胜任力评价量表的编制及信效度检验

Reliability and validity test of a Post Competency Assessment Scale for nurses in central sterile service departments

目的 编制消毒供应中心护士岗位胜任力评价量表并检验其信效度。方法 研究组将前期构建的消毒供应中心护士岗位胜任力评价指标(4个一级指标、58个二级指标)进行指标转换,形成消毒供应中心护士岗位胜任力评价量表。选取6名专家评定量表内容效度。2021年5月—6月,便利选取北京市3所三级甲等综合医院消毒供应中心34名护士进行预调查;2021年9月—10月,便利选取2个省市630名消毒供应中心护士正式调查并进行信效度分析。结果 消毒供应中心护士岗位胜任力评价量表包括理论知识、操作技能、综合能力及个人特质4个维度,共60个条目,量表的内容效度指数为0.970,各条目的内容效度指数为0.830~1.000;探索性因子分析提取4个公因子,累计方差贡献率为71.51%。量表总的Cronbach’s α系数为0.989,折半信度为0.951,重测信度为0.840。结论 构建的消毒供应中心护士岗位胜任力评价量表具有良好的信效度,可作为消毒供应中心护士岗位胜任力的评价工具,为制订相关培训与考核提供参考。

Objective To test the reliability and validity of Post Competency Assessment Scale for nurses in central sterile service departments(CSSD). Methods According to the Iceberg Competency Model,an evaluation index framework for the competency of nurses including 4 first-level indexes and 58 second-level indexes was formed through Delphi consultation in previous research. The members of the research group further transformed the indexes to a 60-item post competency assessment scale for nurses in CSSD. 6 experts assessed the content validity of the scale;from May to June 2021,34 nurses in CSSD from 3 hospitals in Beijing were selected for preliminary survey;from September to October 2021,630 nurses from 2 provinces were selected for formal investigation,so as to test the reliability and validity of scale. Results The scale contained 4 factors,including theoretical knowledge,operational skills,comprehensive ability and personal characteristics,with a total of 60 items. The content validity of the total scale was 0.970,and the scale-level content validity index/average were 0.830~1.000;4 factors were identified by exploratory factor analysis,accounting for 71.51% of the total variance. The overall Cronbach’s α coefficient was 0.989. The overall split-half reliability was 0.951. The test-retest reliability was 0.840. Conclusion The Post Competency Assessment Scale for nurses in CSSD has good reliability and validity. It can be used as a tool to assess the post competency for nurses in CSSD,and a reference for hospitals to make training plans and annual assessment.
