目的:编制适用于我国临床护士的组织支持感问卷并检验其信度和效度。方法:本研究通过文献回顾、半结构式深度访谈和专家咨询形成护士长组织支持感初步问卷;后对上海市401名临床护士进行测试,通过项目分析和探索性因子确定正式问卷,并检验其信度、效度。结果:研制的护士组织支持感问卷为单维度,包含15个条目,探索性因子分析显示该问卷累积方差贡献率为60.825%;问卷内容效度指数为0.940;Cronbach’sα系数为0.953;折半信度为0.909;重测信度为0.812。结论:护士组织支持感问卷信度和效度良好,可以用于测量临床护士的组织支持感。

Objective： To develop the Survey of Nurse Perceived Organizational Support （SNPOS）, and to test its validity and reliability. Methods： Test construction of SNPOS＇s initial version involved systematic generation of test items using literature review, semi-structured in-depth interview of 11 clinical nurses, and an expert consultation of test items. Then, a pilot study, involving 401 clinical nurses, was conducted to determine the SNPOS＇s dimensional structure and psychometric properties by using Item Analysis, Exploratory Factor Analysis （EFA）, and reliability tests. Results： The SNPOS is a unidimensional scale, and comprises 15 items. The Perceived Support factor accounted for 60.825% of the total variances. The Scale-level content validity index （S-CVI） was 0.940. The Cronbach＇s ct was 0.953; the spilt-half reliability was 0.909; and the test-retest reliability was 0.812. Conclusion： The Survey of Nurse Perceived Organizational Support has good validity and reliability, which could be applied to assess clinical nurses＇ perceived organizational support.
