This study aimed to develop a group organizational learning activity inventory for evidence-based practice (EBP) institutionalized by hospitals and to verify its reliability and validity.
A draft inventory was created after verifying content and face validity of draft items developed based on interview data and materials used in EBP implementation. Construct validity and reliability were assessed cross-sectionally through an anonymous self-administered survey conducted via web and printed questionnaires. Construct validity was confirmed using exploratory and confirmatory factor analyses, and internal consistency and convergent/discriminant validity were verified. Inventory structure was determined using the theoretical model based on the hypothetical constructive concept. Temporal stability was assessed two weeks after the initial survey.
A draft inventory comprising 12 factors and 47 items was created based on 95 draft items. Data from 371 nurses across 55 departments in 12 hospitals were analyzed. The inventory comprised 8 factors and 40 items based on the theoretical model. The comparative fit index was 0.86, the Tucker-Lewis index was 0.85, the root mean square error of approximation was 0.09, and standardized root mean square was 0.04. Cronbach's alpha of each factor was ≥0.8, and the temporal stability was moderate.
We developed the group organizational learning activity inventory, comprising 8 factors and 40 items. Though construct validity was low, the reliability and concurrent/convergent validities were confirmed. This inventory contains new factors that measure the group activities to ensure EBP's continuation in hospitals: forming common knowledge, understanding the value of EBP in groups, and fostering ownership thereof. Using this inventory, departments that introduced EBP can evaluate the extent of activities leading to nurses' continuation of EBP and find the improvement point.
本研究旨在开发一份用于医院实施循证实践（EBP）的团体组织学习活动量表，并验证其信效度。
基于访谈数据和EBP实施中使用的材料，在验证初稿项目的内容效度和表面效度后创建了量表初稿。通过网络和纸质问卷进行的匿名自填式横断面调查评估结构效度和信度。使用探索性和验证性因素分析确认结构效度，并验证内部一致性以及收敛效度/区分效度。基于假设构建概念的理论模型确定量表结构。在初次调查两周后评估时间稳定性。
基于95个初稿项目创建了包含12个因素和47个条目的量表初稿。对12家医院55个科室的371名护士的数据进行了分析。基于理论模型，该量表包含8个因素和40个条目。比较拟合指数为0.86，塔克-刘易斯指数为0.85，近似误差均方根为0.09，标准化均方根为0.04。各因素的克朗巴哈系数≥0.8，时间稳定性中等。
我们开发了包含8个因素和40个条目的团体组织学习活动量表。尽管结构效度较低，但信度以及同时效度/收敛效度得到了确认。该量表包含用于衡量确保医院EBP持续开展的团体活动的新因素：形成共同知识、理解团体中EBP的价值以及培养对此的主人翁意识。使用该量表，引入EBP的科室可以评估导致护士持续开展EBP的活动程度，并找到改进点。
