The Harmonized Cognitive Assessment Protocol (HCAP) describes an assessment battery and a family of population-representative studies measuring neuropsychological performance. We describe the factorial structure of the HCAP battery in the US Health and Retirement Study (HRS).
The HCAP battery was compiled from existing measures by a cross-disciplinary and international panel of researchers. The HCAP battery was used in the 2016 wave of the HRS. We used factor analysis methods to assess and refine a theoretically driven single and multiple domain factor structure for tests included in the HCAP battery among 3,347 participants with evaluable performance data.
For the eight domains of cognitive functioning identified (orientation, memory [immediate, delayed, and recognition], set shifting, attention/speed, language/fluency, and visuospatial), all single factor models fit reasonably well, although four of these domains had either 2 or 3 indicators where fit must be perfect and is not informative. Multidimensional models suggested the eight-domain model was overly complex. A five-domain model (orientation, memory delayed and recognition, executive functioning, language/fluency, visuospatial) was identified as a reasonable model for summarizing performance in this sample (standardized root mean square residual = 0.05, root mean square error of approximation = 0.05, confirmatory fit index = 0.94).
The HCAP battery conforms adequately to a multidimensional structure of neuropsychological performance. The derived measurement models can be used to operationalize notions of neurocognitive impairment, and as a starting point for prioritizing pre-statistical harmonization and evaluating configural invariance in cross-national research.
协调认知评估方案（HCAP）描述了一种评估工具包和一系列具有代表性的人群研究，用于衡量神经认知表现。我们描述了 HCAP 电池在健康与退休研究（HRS）中的因子结构。
HCAP 电池由跨学科和国际研究人员小组从现有测量工具中编制而成。HCAP 电池在 HRS 的 2016 波次中使用。我们使用因子分析方法评估和完善 HCAP 电池中包含的测试的单一和多领域理论驱动因子结构，这些测试在 3347 名具有可评估绩效数据的参与者中进行。
对于确定的认知功能的八个领域（定向、记忆[即时、延迟和识别]、定势转移、注意力/速度、语言/流畅性和视空间），所有单一因子模型拟合得相当好，尽管其中四个领域有两个或三个指标，其中拟合必须是完美的，且没有信息。多维模型表明，八领域模型过于复杂。在这个样本中，确定了一个五领域模型（定向、记忆延迟和识别、执行功能、语言/流畅性、视空间）作为总结表现的合理模型（标准化根均方残差=0.05，均方根误差逼近=0.05，验证拟合指数=0.94）。
HCAP 电池充分符合神经认知表现的多维结构。得出的测量模型可用于实现神经认知损伤的概念，并作为优先进行预统计协调和评估跨国研究中配置不变性的起点。
