目的 基于WHO的护理教师核心胜任力(nurse educator core competencies,NECC)框架形成护理教师核心胜任力量表,并检验其信度和效度。方法 通过翻译、回译得到中文版NECC框架,作为护理教师核心胜任力量表的条目,采用李克特4级评分法形成量表初稿,邀请专家评价内容效度,根据专家意见调整问卷后,通过便利抽样选取北京市高校附属医院598名临床护理教师填写问卷。采用探索性结构方程模型(exploratory structural equation modeling,ESEM)评价结构效度,采用相关分析评价效标关联效度,采用克朗巴赫系数评价内部一致性信度,采用Spearman-Brown法计算前后折半信度。结果 量表内容效度指数为0.810;经ESEM分析,χ2值为955.376(P<0.001),近似误差平方根为0.048(0.044~0.052),比较拟合指数为0.992,塔克·刘易斯指数为0.987,加权均方根残差为0.584,最终确定8个维度。量表总分与临床护理教师胜任力模型总分之间显著相关(r=0.599,P<0.001),效标关联效度较好。总体克朗巴赫系数为0.975,各维度克朗巴赫系数为0.830~0.934。折半信度为0.910。结论 基于NECC框架形成的护理教师核心胜任力量表信度和效度可接受,可用于评估国内临床护理教师的核心胜任力。
Objective To development a nurse educator core competencies scale based on the framework of nurse educator core competencies (NECC) developed by World Health Organization, and test its reliability and validity. Methods The Chinese draft was formed by forward and back translation. We invited experts to evaluate its content validity. After adjustment according to experts' comments, a survey was conducted in 598 clinical nursing educators of university affiliated hospitals in Beijing. Exploratory structural equation modeling (ESEM) was used to evaluate construct validity. Correlation analysis was used to evaluate criteria-related validity. Cronbach's α coefficient was used to evaluate the internal reliability, Spearman-Brown coefficient was usedtoevaluate split-half reliability. Results The scale-level content validity index was 0.810. The model fit results of ESEM were χ2=955.376 (P<0.001), Root Mean Square Error of Approximation=0.048 (0.044-0.052), Comparative Fit Index =0.992, Tucker-Lewis Index=0.987, Weighted Root Mean Square Residual=0.584, and finally extracted eight domains. It's total score had significant correlation with the total score of the competency framework for clinical nursing teachers (r=0.599, P<0.001). Criteria-related validity was good. The overall Cronbach's α was 0.975 and the domains' Cronbach's α were 0.830~0.934. Split-half reliability was 0.910. Conclusions The nurse educator core competencies scale based on the NECC framework had acceptable reliability and validity, which could be used to assess the core competencies of clinical nursing educators in our country.
