护士职业嵌入量表的编制及信效度检验

目的 初步编制适用于我国文化背景的护士职业嵌入评估量表并对其进行信效度检验.方法 以嵌入性理论作为编制量表的基本理论框架,通过文献查阅、开放式问卷调查和半结构式访谈初步拟定量表条目库,经过专家评定形成护士职业嵌入量表初稿.采用方便取样法进行3次取样.用第1次预测样本（n=368）和第2次预测样本（n=306）进行项目分析和探索性因素分析,用正式施测样本（n=372）进行验证性因素分析及信度和效标效度检验.从正式施测样本中抽取55名护士间隔2周后重测.以离职倾向量表作为效标.结果 护士职业嵌入量表共18个条目,由匹配、联结和牺牲3个维度构成,累积贡献率为55.321％;验证性因素分析表明量表的模型拟合较好,x2/df=2.563,RMR=0.048,TLI=0.914,CFI=0.925.量表得分与离职倾向得分呈负相关.量表的内部一致性Cronbach α系数为0.917,3个维度的α系数为0.800～0.834.总量表的重测信度为0.890,3个维度的重测信度为0.732～0.873.结论 本研究编制的护士职业嵌入量表信效度指标较好,可作为国内护士职业嵌入的测评工具.

Development and psychometric testing of the occupational embeddedness scale for nurses

Objective To develop the Occupational Embeddedness Scale for Nurses and test its re liability and validity.Methods The original scale was designed according to document analysis,openlabel questionnaire and interview results.After 3 sampling tests,the first predicted sample （n=368） was conducted with item analysis and exploratory factor analysis （EFA）,the second predicted sample （n=306） was conducted with EFA,and then the formal tested sample （n=372） was conducted with confirmatory factor analysis （CFA）.Another sample of 55 nurses was tested and retested two weeks later.The intestine emendatory Turnover Intention Scale was used to test its criterion validity.Results The final scale had 18 items and 3 dimensions,including fit,link and Sacrifice.Occupational Embeddedness Scale revealed good model fit indices （x2/df =2.563,RMR=0.048,TLI=0.914,CFI=0.925）.The total scores was negatively correlated with the Turnover Intention Scale scores.The Cronbach＇s α coefficients of the whole scale was 0.917,and range 0.800～0.834 for each dimension.The test-retest reliability was 0.890,and ranged 0.732～0.873 for each dimension.Conclusions It suggests that the Occupational Embeddedness Scale for Nursing has good reliability and validity,and can be used to assess the occupational embeddedness status of nursing in China.
