护士心理韧性相关执业环境因素评估量表的构建及信效度检验

目的 编制护士心理韧性相关执业环境因素评估量表，并评价其信效度。方法 基于护士心理韧性相关执业环境模型框架，结合文献检索、半结构式访谈、小组讨论构架量表条目池，通过2轮德尔菲专家函询及小样本预调查确定量表初稿。采用便利抽样抽取北京市某三级甲等医院280名护士进行调查，通过项目分析进行条目筛选。采用便利抽样抽取北京市某三级甲等医院694名护士进行正式调查，对量表进行信度分析、探索性因子分析，最终通过验证性因子分析对量表拟合度进行检验，形成正式版量表。结果 护士心理韧性相关执业环境因素评估量表包括职业支持与发展、实践支持与发展以及个人支持与发展3个维度、共32个条目，累计方差贡献率为73.376%。验证性因子分析结果显示，量表的模型适配良好。总量表的Cronbach α系数为0.980,2周后的重测信度为0.940，折半信度为0.931，总量表内容效度指数为0.980。结论 护士心理韧性相关执业环境因素评估量表具有较好的信效度，可用于评估护士执业环境中影响心理韧性的相关因素。

Development and sychometric testing of Nurse Resilience-related Practice Environment Factor Assessment Scale

Objective To develop a nurse resilience-related practice environment factor assessment scale and to test its reliability and validity. Methods Based on the Health Services Workplace Environmental Resilience Model (HSWERM), combined with literature retrieval, semi-structured interview and group discussion, the item pool of the scale was constructed. The scale was modified by two rounds of expert letter consultation using Delphi method. Convenience sampling was used to select 280 nurses in a tertiary grade-A hospital in Beijing for the first investigation, and items were screened through item analysis. Convenience sampling was used to select 694 nurses in a tertiary grade-A hospital in Beijing for the second investigation. Reliability analysis and exploratory factor analysis, and confirmatory factor analysis were conducted to construct the formal scale. Results The nurse resilience-related practice environment factor assessment scale included three dimensions of career support and development, practical support and development, and personal support and development. The scale consisted of 32 items, and the cumulative variance contribution rate was 73.376%. The model fit of the scale was good. The Cronbach’s α coefficient of internal consistency of the total table was 0.980; retest reliability 0.940; half-fold reliability 0.931; and content validity index of the total table 0.980. Conclusion The nurse resilience-related practice environment factor assessment scale has good reliability and validity, and can be used to evaluate the factors affecting mental toughness in nurses’ practice environment.
