The aim of this paper is to report the development and validation of a self-report measure of knowledge, practice and attitudes towards evidence-based practice (EBP).
Evidence-based practice has become increasingly important in health care since the mid-1990s as it provides a framework for clinical problem-solving. However, to date no means exist to quantify the extent to which barriers, such as lack of time in the working day, lack of appropriate skills and negative attitudes, may prevent greater uptake of EBP.
Questionnaire development was based on established psychometric methods. Principal component factor analysis was used to uncover the underlying dimensions of the scale. Internal consistency of the scale was assessed by Cronbach's alpha. Finally, construct validity was assessed via convergent and discriminant validity.
The final questionnaire comprised three distinct scales (EBP, attitudes towards EBP and knowledge of EBP), which had robust validity and internal reliability.
This tool can be used to measure the implementation of EBP.
本文旨在报告一项关于循证实践（EBP）的知识、实践和态度的自我报告测量工具的开发与验证情况。
自20世纪90年代中期以来，循证实践在医疗保健领域变得越来越重要，因为它为临床问题解决提供了一个框架。然而，迄今为止，尚无方法来量化诸如工作日时间不足、缺乏适当技能和消极态度等障碍可能在多大程度上阻碍循证实践的更多采用。
问卷开发基于既定的心理测量方法。主成分因子分析用于揭示该量表的潜在维度。量表的内部一致性通过克朗巴哈α系数进行评估。最后，通过收敛效度和区分效度评估结构效度。
最终问卷由三个不同的量表（循证实践、对循证实践的态度和循证实践知识）组成，具有较强的效度和内部信度。
该工具可用于测量循证实践的实施情况。
