Everyday Cognition (ECog) has been widely used to differentiate individuals with mild cognitive impairment (MCI) and dementia from normal elderly individuals. It has also been used to assess subjective cognitive decline (SCD). This study investigated the feasibility of using ECog as a screening measure for SCD in community-dwelling elderly individuals.
The participants included 84 older adults with and 93 without SCD living in the community. These 2 groups were classified based on their response ("yes" or "no") to the question "Do you perceive memory or cognitive difficulties?" All participants were evaluated using the Korean-Mini Mental State Examination (K-MMSE), Short form of the Geriatric Depression Scale (SGDS), and the Korean version of Everyday Cognition (K-ECog).
The scores of all participants were within the normal range on the K-MMSE and SGDS. The total K-MMSE score did not differ significantly between the 2 groups after controlling for age, education, and depression. The scores of SCD group were significantly higher than those of the non-SCD group for memory, language, and executive function: planning domains, as well as K-ECog total score. Receiver operating characteristic curve analysis revealed that the K-ECog total score was effective in moderately differentiating between subjects with and without SCD (area under the curve: 0.73).
ECog is a feasible and useful screening measure for SCD in older adults living in the community, and can be used to assess the full spectrum of cognitive and functional deficits, ranging from SCD to MCI and dementia.
日常认知（ECog）已被广泛用于区分轻度认知障碍（MCI）和痴呆患者与正常老年人。它也被用于评估主观认知下降（SCD）。本研究调查了将ECog用作社区居住老年人SCD筛查指标的可行性。
参与者包括84名社区中患有SCD的老年人和93名未患SCD的老年人。这两组是根据他们对“你是否察觉到记忆或认知困难？”这个问题的回答（“是”或“否”）来划分的。所有参与者均接受韩国简易精神状态检查表（K-MMSE）、老年抑郁量表简表（SGDS）以及韩语版日常认知量表（K-ECog）的评估。
所有参与者在K-MMSE和SGDS上的得分均在正常范围内。在控制年龄、教育程度和抑郁因素后，两组之间的K-MMSE总分无显著差异。SCD组在记忆、语言、执行功能：计划领域以及K-ECog总分方面的得分显著高于非SCD组。受试者工作特征曲线分析显示，K-ECog总分在适度区分有和没有SCD的受试者方面是有效的（曲线下面积：0.73）。
ECog是社区居住老年人SCD的一种可行且有用的筛查指标，可用于评估从SCD到MCI和痴呆的全谱认知和功能缺陷。
