The Nurse Competence Scale is a tool for evaluating nursing clinical competence. This tool has been used and psychometrically validated previously in different countries but never in Italy. Assessing the validity and reliability of the Nurse Competence Scale in the Italian context has been a strong necessity for many years.
To test the psychometric properties and evaluate the internal construct validity of the Italian version of the Nurse Competence Scale.
This study is a secondary analysis on a database of 698 bachelor nursing students who were trained in different clinical settings at two Italian universities. Internal consistency was examined with Cronbach's alpha coefficients and inter-item analysis, and construct validity was evaluated by Exploratory Factor Analysis with Oblimin rotation with Kaiser normalization, and eventually Confirmatory Factor Analysis.
The results highlighted the necessity for refinements of the Nurse Competence Scale in the Italian Context. The original model of the Nurse Competence Scale (73 items) was not confirmed. The confirmatory factor analysis presented significant values of Chi-squared test = 10942.766, with degrees of freedom being 2.534 and a ratio of χ²/df = 4.318. The Comparative Fit Index value was significant 0.809 and the Normed Fit Index 0.765 was noteworthy too. The value of Root Mean Square Error of Approximation was significant 0.069. The Cronbach's α coefficient for the new scale was excellent (0.922). The exploratory factor analysis resulted in the Italian Nurse Competence Scale composed of 58 items divided into seven dimensions: using the research, professional awareness, ethical values, tutorial functions, professional leadership, educational interventions, and management of care processes.
The Italian version of the Nurse Competence Scale with 7 dimension and 58 items is an appropriate tool for describing and comparing self-assessed competencies by nurses. Such evaluations could constitute an important contribution to have better educational environments. Self-assessment of competencies can also raise a stronger awareness of individual educational needs.
护士能力量表是一种用于评估护理临床能力的工具。该工具此前已在不同国家使用并经过心理测量学验证，但在意大利从未使用过。多年来，在意大利背景下评估护士能力量表的有效性和可靠性一直是一项迫切需求。
测试意大利版护士能力量表的心理测量特性并评估其内部结构效度。
本研究是对698名在意大利两所大学不同临床环境中接受培训的本科护理学生数据库进行的二次分析。使用克朗巴哈α系数和项目间分析检查内部一致性，并通过采用Kaiser标准化的斜交旋转探索性因素分析以及最终的验证性因素分析来评估结构效度。
结果凸显了在意大利背景下对护士能力量表进行完善的必要性。护士能力量表的原始模型（73个项目）未得到证实。验证性因素分析显示卡方检验值显著，为10942.766，自由度为2534，χ²/df比率为4.318。比较拟合指数值显著为0.809，规范拟合指数0.765也值得注意。近似均方根误差值显著为0.069。新量表的克朗巴哈α系数极佳（0.922）。探索性因素分析得出意大利护士能力量表由58个项目组成，分为七个维度：运用研究、专业意识、伦理价值观、指导功能、专业领导力、教育干预和护理过程管理。
具有七个维度和58个项目的意大利版护士能力量表是描述和比较护士自我评估能力的合适工具。此类评估可为营造更好的教育环境做出重要贡献。能力的自我评估还可提高对个人教育需求的更强认识。
