AIM
To conduct a construct validity test on a clinical nurse specialist core competency scale.
BACKGROUND
Clinical nurse specialists' competency development dates back to the late 20th century; however, there is scarcity of competency descriptions from outside of North America. Furthermore, little knowledge is available on the previous research-driven efforts to develop and validate clinical nurse specialist core competencies.
DESIGN
A descriptive study, using an online self-report questionnaire, was conducted from May to September 2019 in three Nordic countries.
METHODS
An exploratory factor analysis using principal axis factoring and rotation method oblimin with Kaiser normalisation was undertaken to examine factors in the 50-item scale. Parallel analysis with eigenvalue Monte Carlo simulation and scree plot was used to determine the number of factors to extract. Psychometric properties of the scale were evaluated, and subjective interpretation was used to modify the tool in line with the statistical analysis. The STROBE checklist was used as the reporting guideline for this study.
RESULTS
One hundred and eighty-four responses were obtained (Finland n = 52, Denmark n = 95, Iceland n = 37) with an overall response rate of 45%. The results provided construct validity evidence of the underlying theoretical structures of the four competency spheres of patient, nursing, organisation and scholarship. Cronbach's alpha coefficient for the original overall scale was 0.94, thus indicating adequate reliability of the scale.
CONCLUSIONS
Based on the analysis and subjective interpretation, we suggest a 47-item clinical nurse specialist core competency scale. Further study should be conducted to validate the core competency content and construct in other contexts beyond the present study.
RELEVANCE TO CLINICAL PRACTICE
The scale may be used to guide clinical nurse specialist practice and identify areas for professional development, develop graduate-level programme curricula and inform future competency research.
目的
对临床护理专家核心能力量表进行结构效度检验。
背景
临床护理专家的能力发展可以追溯到 20 世纪后期；然而，北美的能力描述却很少。此外，对于以前以研究为基础的开发和验证临床护理专家核心能力的努力，人们知之甚少。
设计
这是一项描述性研究，于 2019 年 5 月至 9 月在三个北欧国家使用在线自我报告问卷进行。
方法
采用主轴因子分析和 oblimin 旋转方法，使用 Kaiser 正态化对 50 项量表进行探索性因子分析。使用特征值蒙特卡罗模拟和碎石图进行平行分析，以确定要提取的因子数量。评估量表的心理测量特性，并使用主观解释根据统计分析修改工具。本研究使用 STROBE 清单作为报告指南。
结果
共收到 184 份回复（芬兰 n=52，丹麦 n=95，冰岛 n=37），总体回复率为 45%。结果提供了四个能力领域（患者、护理、组织和学术）的潜在理论结构的结构效度证据。原始总量表的克朗巴赫α系数为 0.94，表明该量表具有足够的可靠性。
结论
基于分析和主观解释，我们建议使用 47 项临床护理专家核心能力量表。应在本研究之外的其他背景下进一步研究该量表的核心能力内容和结构的验证。
临床意义
该量表可用于指导临床护理专家实践，确定专业发展领域，开发研究生课程课程，并为未来的能力研究提供信息。
