护士长变革型领导力自评量表的研制及信效度检验

The development of Head Nurse’s Transformational Leadership Self-rating Scale and the best of its reliability and validity

目的研制护士长变革型领导力自评量表并检验其信效度。方法通过文献回顾法、半结构式访谈法、德尔菲专家咨询法形成量表初稿。对湖北省某三级甲等医院210名护士长进行预测试,采用项目分析、探索性因子分析进行量表条目筛选。对湖北省18所三级甲等医院的922名护士长进行正式测试,采用SPSS和AMOS软件对问卷进行信度分析及验证性因子分析。结果护士长变革型领导力自评量表包含4个维度25个条目,解释了总变异量的61.092%,量表的Cronbach’sα系数为0.940,分半信度系数为0.895;护士长变革型领导力自评量表一阶多因子模型的适配度指标分别为:卡方/自由度为23.251,拟合优度指数为0.919,修正的拟合优度指数为0.902,比较拟合指数为0.910,Tucker-Lewis指标为0.900,近似误差平方根为0.049。结论护士长变革型领导力自评量表具有良好的信效度,可用于评价我国护士长的变革型领导力。

Objective To develop the Head Nurse’s Transformational Leadership Self-rating Scale and verify its reliability and validity.Methods The scale was initially developed through literature review,semi-structure interviews and Delphi consultation.A total of 210 head nurses from a tertiary hospital in Wuhan were selected to conduct a pilot test.Item analysis and exploratory factor analysis were used to screen items.A total of 922 nurses from 18 tertiary hospitals in Hubei Province were recruited to conduct the formal test.The reliability analysis and confirmatory factor analysis were conducted using SPSS and AMOS software.Results The Head Nurse’s Transformational Leadership Self-rating Scale contained 4 dimensions and 25 items.The 4 demensions explained 61.092%of the total variance.The Cronbach’sαcoefficient of the scale was 0.940,and the split-half reliability coefficient was 0.895.The one-dimension/multi-factor model’s CMIN/DF was 23.251,GFI was 0.919,AGFI was 0.902,CFI was 0.910,TLI was 0.900,and RMSEA was 0.049.Conclusion The Head Nurse’s Transformational Leadership Self-rating Scale can be used to evaluate the head nurse’s transformational leadership in Chinese context with good reliability and validity.
