本初步研究旨在探讨认知功能工具（CFI）作为主观认知抱怨（SCC）测量的心理测量特性，以及与客观认知筛查（蒙特利尔认知评估[MoCA]）相比，CFI在区分轻度认知障碍（MCI）和正常对照（NC）方面的表现。方法纳入194名居住在社区的不同种族/民族的无痴呆老年人。采用因子分析、Cronbach’s alpha和McDonald’s omega检验CFI的单维性和内部一致性。采用Logistic回归模型和受试者工作特征（ROC）分析来检验CFI的绩效。结果CFI具有足够的内部一致性；然而，一维模型的拟合不是最优的。CFI将MCI与NC单独或与MoCA联合区分开来。ROC分析显示CFI和MoCA的性能相当。我们的研究结果支持使用CFI作为一种简单且易于使用的筛查来检测文化/语言不同的老年人的MCI。论文的核心科学问题是什么？主观认知抱怨（SCCs）被认为是老年痴呆症的最早征兆。然而，尚不清楚SCC在不同文化中是否相同。认知功能量表（CFI）是一个包含14个项目的SCC测量量表。本研究提供的试点数据表明，CFI对于检测具有种族/民族多样性的老年人队列中的轻度认知障碍是敏感的。比较表现，CFI表现出与蒙特利尔认知评估相当的敏感性，这是一种客观的认知筛选测试。总的来说，SCC可以提供一种非侵入性的、易于使用的方法来标记研究和临床环境中可能存在的认知障碍。
IntroductionThis pilot study aims to explore the psychometric properties of the Cognitive Function Instrument (CFI) as a measure of subjective cognitive complaints (SCC) and its performance in distinguishing mild cognitive impairment (MCI) from normal control (NC) compared to an objective cognitive screen (Montreal Cognitive Assessment [MoCA]).MethodsOne hundred ninety‐four community‐dwelling non‐demented older adults with racial/ethnic diversity were included. Unidimensionality and internal consistency of the CFI were examined using factor analysis, Cronbach's alpha, and McDonald's omega. Logistic regression models and receiver operating characteristic (ROC) analysis were used to examine the performance of CFI.ResultsThe CFI demonstrated adequate internal consistency; however, the fit for a unidimensional model was suboptimal. The CFI distinguished MCI from NC alone or in combination with MoCA. ROC analysis showed comparable performance of the CFI and the MoCA.DiscussionOur findings support the use of CFI as a brief and easy‐to‐use screen to detect MCI in culturally/linguistically diverse older adults.HighlightWhat is the key scientific question or problem of central interest of the paper?Subjective cognitive complaints (SCCs) are considered the earliest sign of dementia in older adults. However, it is unclear if SCC are equivalent in different cultures. The Cognitive Function Instrument (CFI) is a 14‐item measure of SCC. This study provides pilot data suggesting that CFI is sensitive for detecting mild cognitive impairment in a cohort of older adults with racial/ethnic diversity. Comparing performance, CFI demonstrates comparable sensitivity to the Montreal Cognitive Assessment, an objective cognitive screening test. Overall, SCC may provide a non‐invasive, easy‐to‐use method to flag possible cognitive impairment in both research and clinical settings.
