背景：为了更好地了解如何改进州卫生部门的循证决策 (EBDM)，需要测量工具来评估 EBDM 的变化。本研究的目的是测试一种新的测量工具的心理测量特性，以评估公共卫生实践环境中的 EBDM。方法：根据公共卫生从业者的意见，在迭代过程中开发、试点测试和完善调查问卷，旨在确定代表 EBDM 不同组成部分的一组具体措施。数据是在对州卫生部门慢性病从业人员的全国调查中收集的。心理测试的最终数据集 (n=879) 由 19 个 EBDM 项目组成，首先使用探索性因素分析进行检查，然后进行验证性因素分析。结果：验证性因素分析的最终模型包括代表 EBDM 组成部分的五个潜在因素：评估能力、EBDM 的期望和激励、EBDM 证据和资源的获取、参与性决策以及领导支持和承诺。结论：本研究满足了实证测试和验证的需求。与理论一致的措施可用于评估当前实施 EBDM 的程度，并进一步衡量公共卫生环境中改进 EBDM 策略的成功程度。该 EBDM 测量工具可能有助于确定增强能力和实施有效策略所需的支持。 (C) 2016 年由爱思唯尔有限公司出版。
Background: In order to better understand how to improve evidence-based decision making (EBDM) in state health departments, measurement tools are needed to evaluate changes in EBDM. The purpose of this study was to test the psychometric properties of a new measurement tool to assess EBDM in public health practice settings.Methods: A questionnaire was developed, pilot-tested and refined in an iterative process with the input of public health practitioners with the aim of identifying a set of specific measures representing different components of EBDM. Data were collected in a national survey of state health department chronic disease practitioners. The final dataset (n=879) for psychometric testing was comprised of 19 EBDM items that were first examined using exploratory factor analysis, and then confirmatory factor analysis.Results: The final model from confirmatory factor analysis includes five latent factors representing components of EBDM: capacity for evaluation, expectations and incentives for EBDM, access to evidence and resources for EBDM, participatory decision making, and leadership support and commitment.Conclusions: This study addresses the need for empirically tested and theory-aligned measures that may be used to assess the extent to which EBDM is currently implemented, and further, to gauge the success of strategies to improve EBDM, in public health settings. This EBDM measurement tool may help identify needed supports for enhanced capacity and implementation of effective strategies. (C) 2016 Published by Elsevier Ltd.
