护士创新行为量表的研制及信度和效度检验

Development and analysis of reliability and validity of Nurse Innovative Behavior Scale

目的研制适用于护士的创新行为量表。方法根据文献回顾对护士创新行为进行定义,通过对12名临床护士的半结构式访谈形成3个测量维度和15个题项,并采用专家咨询法对题项进行初步筛选。在上海市2所综合性医院的234名护士中进行测试,根据项目分析和探索性因子分析结果筛选题项,并对量表的信度和效度进行检验。结果共发放问卷234份,回收有效问卷206份,有效回收率88.03%。经专家咨询、项目分析和探索性因子分析得到3个因子(产生想法、取得支持和实现想法),共10个题项,与理论框架相一致。3个因子可累计解释总方差的72.012%,各维度与总分的相关系数高于维度间的相关系数,总量表的内容效度为0.91,内部一致性Cronbach’sα系数为0.879。结论护士创新行为量表具有较好的信度和效度,为测量护士创新行为提供了依据。

Objective To develop a scale for measurement of nurse innovative behavior. Methods Nurse innovative behavior was defined on the basis of literature review. Three dimensions and 15 items were formulated by semi-structured interview among 12 nurses, and the items were screened with expert evaluation. Two hundred and thirty-four nurses in 2 hospitals in Shanghai were investigated with the scale, item analysis and exploratory factor analysis were conducted, and the reliability and validity of the scale were examined. Results Two hundred and six effective questionnaires were recovered, with the recovery rate of 88.03%. Through expert evaluation, item analysis and exploratory factor analysis, a 10-item Nurse Innovative Behavior Scale was developed, which included 3 factors （idea generation, support obtaining and idea realization） and was consistent with theoretical construct. These three factors accounted for 72. 012% of the accumulated variances. The correlation coefficients between dimensions and total scale were higher than those between dimensions. The content validity index was 0.91, and the Cronbach＇s c~ was 0. 879. Conclusion Nurse Innovative Behavior Scale has a good reliability and validity, providing a tool to measure nurse innovative behavior.
