目的 构建院前急救护士核心素养评价量表并进行信效度检验。方法 基于能岗匹配理论，采用文献回顾、半结构式访谈，初步拟定院前急救护士核心素养评价量表条目池；通过Delphi专家函询、层次分析法及预调查，形成初始量表。于2023年10—11月，采用方便抽样法选取山东省16个市(区)53所三级甲等综合医院的院前急救护士作为调查对象，进行量表的项目分析、信效度检验及K-均值聚类划分等级。结果 回收有效问卷576份，回收率96%。院前急救护士核心素养评价量表包括3个维度、49个条目。2轮函询专家积极度均为100%;专家权威系数分别为0.788、0.806;专家肯德尔和谐系数分别为0.188和0.221(均P<0.05)。量表水平的内容效度指数为0.987,探索性因子分析提取10个公因子，累计方差贡献率为83.701%;验证性因子分析结果显示模型拟合较好；条目水平的内容效度指数为0.930～1.000;量表总的Cronbach′s α系数为0.959,折半信度为0.838,重测信度为0.999。K-均值聚类分析法显示，低水平为0～2.19分；中等水平为2.20～3.28分；高水平为3.29～4.00分。结论 院前急救护士核心素养评价量表具有良好的信效度，能客观地评价院前急救护士核心素养水平，对院前急救护士的准入、培训及考核具有一定的借鉴、指导意义。

Objective To construct the core literacy evaluation scale of pre-hospital emergency nurses and conduct its reliability and validity test. Methods Based on the theory of ability and post matching, literature review and semi-structured interviews were used to preliminarily develop a pool of items for the evaluation of core competencies of pre-hospital emergency nurses; The initial scale was formed through Delphi expert inquiry, analytic hierarchy process, and pre-survey. From October to November 2023, a convenient sampling method was used to select pre-hospital emergency nurses from 53 tertiary Grade A comprehensive hospitals in 16 cities(districts) in Shandong province as the survey subjects for item analysis, reliability and validity test, and K-means clustering classification of the scale. Results A total of 576 valid questionnaires were collected, with a response rate of 96%. The core literacy evaluation scale of pre-hospital emergency nurses included 3 dimensions and 49 items. The enthusiasm of 2 rounds of inquiry experts were 100%; The expert authority coefficients were 0.788 and 0.806, respectively; The Kendall harmony coefficients of experts were 0.188 and 0.221, respectively(both P<0.05). The average content validity index of the scale was 0.987, and exploratory factor analysis extracted 10 common factors, and the cumulative variance contribution rate was 83.701%; The results of confirmatory factor analysis showed that the model fitted well. The content validity index for the entries ranged from 0.930 to 1.000, and the total Cronbach′s α coefficient of the scale was 0.959, with a half reliability of 0.838 and a retest reliability of 0.999. The K-means clustering analysis method showed that the low level was 0-2.19 points; The average score was 2.20-3.28 points; The high level was 3.29-4.00 points. Conclusion The core literacy evaluation scale of pre-hospital emergency nurses has good reliability and validity, which can objectively evaluate the core literacy level of pre-hospital emergency nurses, and has certain reference and guidance significance for the access, training, and assessment of pre-hospital emergency nurses.
