The overall purpose of this study was to evaluate the validity and reliability of the Caring Assessment Tool-Administration survey. Three specific aims were to (1) evaluate construct validity of the Caring Assessment Tool-Administration survey by testing the hypothesized eight-factor structure of staff nurses' perceptions of nurse manager caring behaviors, (2) estimate the internal consistency, and (3) conduct item reduction analysis.
A 94-item Caring Assessment Tool-Administration designed to assess nurse manager caring behaviors appeared in the literature but lacked robust psychometric testing. Using a foundational theory and a cross-sectional descriptive design, the Caring Assessment Tool-Administration was evaluated for reliability and construct validity. Using convenience sampling, 1143 registered nurses were recruited from acute care hospitals in three states located in the Midwestern, Mid-Atlantic, and Southern Regions of the United States.
Psychometric testing of the Caring Assessment Tool-Administration was conducted using confirmatory analysis to determine the dimensionality of the construct, nurse manager caring behavior. The null hypothesis was an eight-factor solution fitting the theoretical model being tested. The null hypothesis was rejected because none of the measures examined for goodness of fit indicated the model fit the data. Confirmatory factor analysis did not support the hypothesized structure; however, exploratory factor analysis supported a one-factor solution that was conceptually labeled . To decrease subject burden, the 94-item survey was reduced to 25 items using item reduction analysis including assessing minimum factor loadings of ≥0.60 and evaluating survey item-total correlation and alpha. The Cronbach's alpha of the new 25-item survey was 0.98.
The new 25-item Caring Assessment Tool-Administration survey provides hospital administrators, nurse managers, and researchers with a sound, less burdensome instrument to collect valuable information about nurse manager caring behaviors.
本研究的总体目的是评估护理关怀评估工具——管理调查问卷的有效性和可靠性。三个具体目标是：（1）通过测试护士对护士长关怀行为认知的假设八因素结构，评估护理关怀评估工具——管理调查问卷的结构效度；（2）估计内部一致性；（3）进行项目缩减分析。
文献中出现了一个旨在评估护士长关怀行为的94项护理关怀评估工具——管理调查问卷，但缺乏有力的心理测量测试。采用基础理论和横断面描述性设计，对护理关怀评估工具——管理调查问卷的可靠性和结构效度进行评估。采用便利抽样法，从美国中西部、中大西洋和南部地区三个州的急症护理医院招募了1143名注册护士。
使用验证性分析对护理关怀评估工具——管理调查问卷进行心理测量测试，以确定护士长关怀行为这一结构的维度。原假设是一个八因素解决方案符合正在测试的理论模型。原假设被拒绝，因为所检验的拟合优度指标均未表明模型与数据拟合。验证性因素分析不支持假设的结构；然而，探索性因素分析支持一个单因素解决方案，从概念上标记为 。为减轻受试者负担，使用项目缩减分析将94项调查问卷缩减至25项，包括评估最小因子载荷≥0.60以及评估调查问卷项目与总分的相关性和阿尔法系数。新的25项调查问卷的克朗巴哈系数为0.98。
新的25项护理关怀评估工具——管理调查问卷为医院管理人员、护士长和研究人员提供了一个可靠、负担较轻的工具，用于收集有关护士长关怀行为的有价值信息。
