血液透析护士动静脉内瘘物理检查知信行量表的编制及信效度检验

Development of an Arteriovenous Fistula Physical Examination Knowledge,Attitude,and Practice Scale for Hemodialysis Nurses and its reliability and validity

目的编制血液透析护士动静脉内瘘物理检查知信行量表,并检验其信效度。方法以知信行理论为框架,通过文献回顾、3轮德尔菲专家咨询及预调查形成量表初稿。采用便利抽样法,于2022年12月—2023年2月选取311名血液透析护士进行调查,用于项目分析、探索性因子分析和信度检验;于2023年2—6月选取260名血液透析护士进行调查,用于验证性因子分析、聚敛效度和区分效度检验。结果血液透析护士动静脉内瘘物理检查知信行量表包括知识、态度和行为3个分量表,5个维度,共33个条目。条目水平的内容效度为0.867~1.000,量表水平的内容效度为0.992。经过探索性因子分析,知识、态度和行为分量表分别提取2个、1个和2个公因子,累积方差贡献率分别为70.114%、75.192%,67.467%。验证性因子分析结果显示模型拟合良好。3个分量表的Cronbach'sα系数为0.929~0.943,折半信度系数分别为0.861~0.903,重测信度系数为0.824~0.874。结论血液透析护士动静脉内瘘物理检查知信行量表具有良好的信效度,可用于评估血液透析护士动静脉内瘘物理检查能力。

Objective To develop an Arteriovenous Fistula Physical Examination Knowledge,Attitude,and Practice Scale for Hemodialysis Nurses and test its reliability and validity.Methods Based on the theory of knowledge,attitude,and practice,a preliminary scale draft was formed through a literature review,three rounds of Delphi expert consultation,and a pre-survey.Using convenience sampling,311 hemodialysis nurses were selected for a survey from December 2022 to February 2023 for item analysis,exploratory factor analysis and reliability testing.Another survey was conducted on 260 hemodialysis nurses from February to June 2023 for confirmatory factor analysis,convergent validity,and discriminant validity testing.Results The Arteriovenous Fistula Physical Examination Knowledge,Attitude,and Practice Scale for Hemodialysis Nurses included three subscales and five dimensions,with a total of 33 items.The content validity index at the item level was 0.867 to 1.000,and the content validity index at the scale level was 0.992.After exploratory factor analysis,two,one,and two common factors were extracted from the knowledge,attitude,and practice subscales,with cumulative variance contribution rates of 70.114%,75.192%,and 67.467%,respectively.Confirmatory factor analysis showed that the model fitted well.The Cronbach'sαcoefficients of the three subscales were 0.929 to 0.943,the half reliability coefficients were 0.861 to 0.903,and the retest reliability coefficients were 0.824 to 0.874.Conclusions The Arteriovenous Fistula Physical Examination Knowledge,Attitude,and Practice Scale for Hemodialysis Nurses has good reliability and validity and can be used to evaluate the physical examination ability of hemodialysis nurses for arteriovenous fistula.
