护士工作满意度量表的信效度分析

Reliability and validity analysis of nurse job satisfaction scale

目的对层次分析法构建的护士满意度量表进行信效度分析,从而制定出符合目前护理工作实际的护士工作满意度量表,为医院管理决策提供真实可靠的理论依据.方法应用一致性信度检验方法,对构建的护士工作满意度指标进行信度研究,测定量表的结构效度,验证量表可行性.①应用一致性信度检验方法"Cronbachα"系数和"分半信度"对量表进行信度研究,删除内部一致性不高的条目,测定量表的信度;②进行KMO(Kaiser-Meyer-Olkin)抽样适当性检验及Bartlett球形检验,采用主成分分析法(Principal component analy-sis)提取因子,采用最大方差法(Varimax)进行旋转,测定量表的结构效度,进一步验证量表的可行性.结果量表的Cronbachα系数为0.945,分半信度值为0.901.量表KMO值为0.922,Bartlett球形检验的χ^2值为8 186.019(P=0.000),说明适合因子分析.8个初始因子的特征值大于1,累计贡献率为64.437.从碎石图提取保留四个因子,根据信效度结果对条目进行删减,最终形成4个因子、29个项目的护士满意度调查量表.结论本研究护士满意度量表层次分明、结构清晰、内容全面,具有可靠的信度与效度,能够应用于临床,可对临床护理提供指导.

Objective To analyze the reliability and validity of the nurses'satisfaction scale constructed by the analytic hierarchy process,so as to develop the nurses'job satisfaction scale in line with the current nursing practice and provide a real and reliable theoretical basis for hospital management decisions.Methods The consistency reliability test method was applied to study the reliability of the constructed index of nurses'job satisfaction,measure the scale's structural validity,and verify the scale's feasibility.①The"Cronbachα"coefficient and"partial reliability"were used to test the reliability of the scale.Items with low internal consistency were deleted to determine the reliability of the scale.②KMO(Kaiser-Meyer-Olkin)sampling suitability test and Bartlett sphericity test were carried out.Principal component analysis was used to extract factors and Varimax was used for rotation to determine the structural validity of the scale and further verify the feasibility of the scale.Results The Cronbachαcoefficient of the scale was 0.945 and the split-half reliability value was 0.901.The KMO value of the scale was 0.922 and theχ^2 value of the Bartlett spheri-cal test was 8 186.019(P=0.000),that was suitable for factor analysis.The characteristic value of the eight initial factors was bigger than 1 and the cumulative contribution rate was 64.437.Four factors were extracted from the gravel map and the entries were cut according to the results of the validity.Finally,four factors were formed and the nurses'satisfaction survey scale consisted of 29 items.Conclusions In this study,the nurse satisfaction scale has a clear hi-erarchy,clear structure and comprehensive content,with reliable reliability and validity,which can be applied in clin-ical practice and provide guidance for clinical nursing.
