认知能力筛查仪 (CASI) 是一种用于研究和临床环境的整体认知功能筛查测试。然而，CASI 是使用表面效度开发的，尚未通过因子分析等实证检验进行研究。因此，我们的目标是开发和测试 CASI 的简约概念，该概念植根于反映结晶和流动能力的认知衰老文献。二次数据分析实施验证性因素分析，其中我们测试了提议的双因素解决方案、替代单因素解决方案，并进行了 X2 差异测试以确定哪个模型具有明显更好的拟合。不适用 数据来自 Kuakini 檀香山亚洲老龄化研究的 3,491 名男性。认知能力筛查仪。研究结果表明，这两个模型都符合数据；然而，二因素模型的拟合效果明显好于一因素模型。标准有效性测试表明，参与者年龄与这两个因素呈负相关，而教育程度与这两个因素呈正相关。进一步的测试表明，液体能力与晚年痴呆症诊断呈显着负相关。我们鼓励研究人员使用 CASI 的双因素模型，因为它可以揭示潜在的认知过程，这可能比使用全局认知测量提供更多信息。
The Cognitive Abilities Screening Instrument (CASI) is a screening test of global cognitive function used in research and clinical settings. However, the CASI was developed using face validity and has not been investigated via empirical tests such as factor analyses. Thus, we aimed to develop and test a parsimonious conceptualization of the CASI rooted in cognitive aging literature reflective of crystallized and fluid abilities. Secondary data analysis implementing confirmatory factor analyses where we tested the proposed two-factor solution, an alternate one-factor solution, and conducted a X2 difference test to determine which model had a significantly better fit. N/A Data came from 3,491 men from the Kuakini Honolulu-Asia Aging Study. The Cognitive Abilities Screening Instrument. Findings demonstrated that both models fit the data; however, the two-factor model had a significantly better fit than the one-factor model. Criterion validity tests indicated that participant age was negatively associated with both factors and that education was positively associated with both factors. Further tests demonstrated that fluid abilities were significantly and negatively associated with a later life dementia diagnosis. We encourage investigators to use the two-factor model of the CASI as it could shed light on underlying cognitive processes, which may be more informative than using a global measure of cognition.
