Evidence-based practice (EBP) improves the quality of care, decreases healthcare costs, and improves job satisfaction. However, nurses and other clinicians, as well as their institutions, struggle to consistently implement EBP. The Advancing Research and Clinical practice through close Collaboration (ARCC©) Model established that a cadre of EBP mentors is key to improving EBP knowledge, beliefs, competency, and implementation in clinicians. Yet, there has not been a valid and reliable measure of EBP mentorship.
The aim of this study was to determine the psychometric properties of the new 8-item EBP Mentorship Scale. This scale measures the degree to which clinicians perceive that EBP mentorship is available to them.
The EBP Mentorship Scale data were obtained from a previous national cross-sectional descriptive study with 2344 nurses from 19 hospitals and healthcare systems. Descriptive statistics summarized the sample and distributions of the scale items. Cronbach's alpha, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were conducted.
Cronbach's alpha of the scale was 0.99. A one-factor model was supported by EFA and retained for CFA. Model fit indices for CFA indicated a good fit.
The new EBP Mentorship Scale is valid and reliable and can be used to assess the level of EBP mentorship support available in hospitals and healthcare systems. EBP mentors are key in sustaining an EBP organizational culture and enhancing clinician EBP knowledge, beliefs, competency, and implementation.
循证实践（EBP）可提高护理质量、降低医疗成本并提高工作满意度。然而，护士和其他临床医生及其所在机构在持续实施 EBP 方面仍面临困难。通过密切合作推进研究和临床实践（ARCC©）模式表明，EBP 导师骨干是提高临床医生 EBP 知识、信念、能力和实施的关键。然而，目前还没有一种有效的、可靠的 EBP 指导衡量方法。
本研究旨在确定新的 8 项 EBP 指导量表的心理测量特性。该量表用于衡量临床医生对 EBP 指导的可获得程度。
EBP 指导量表的数据来自先前一项全国性的横断面描述性研究，共纳入来自 19 家医院和医疗保健系统的 2344 名护士。描述性统计总结了样本和量表项目的分布情况。进行了克朗巴赫α系数、探索性因子分析（EFA）和验证性因子分析（CFA）。
该量表的克朗巴赫α系数为 0.99。EFA 支持单因素模型，并保留用于 CFA。CFA 的模型拟合指数表明拟合良好。
新的 EBP 指导量表具有有效性和可靠性，可用于评估医院和医疗保健系统中 EBP 指导支持的水平。EBP 导师在维持 EBP 组织文化以及增强临床医生 EBP 知识、信念、能力和实施方面发挥着关键作用。
