The present study examined whether subjective age is related to informant-rated cognition. Participants were adults (N = 2,337, mean age = 69.84 years, SD = 7.45) from the Health and Retirement Study who provided subjective age and demographic factors in 2008/2010 and informant-rated cognition in 2016 as part of the Harmonized Cognitive Assessment Protocol. An older subjective age was associated with informant reports of steeper cognitive decline, worse cognitive function, lower ability, and loss of ability to do everyday activities. The present study indicates that subjective age predicts cognitive function in everyday life as observed by knowledgeable informants. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

主观年龄和知情者评级的认知与功能：一项前瞻性研究。

本研究检查了主观年龄是否与知情者的认知有关。参加者是健康与退休研究的成年人（N = 2,337，平均年龄= 69.84岁，SD = 7.45），他们在2008/2010年提供了主观年龄和人口统计学因素，并在2016年作为统一认知评估协议的一部分提供了知情者评级的认知。主观年龄较大与知情者报告有关，其认知能力下降较快，认知功能较差，能力较低以及日常活动能力下降。本研究表明，如知识渊博的信息提供者所观察到的那样，主观年龄可以预测日常生活中的认知功能。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
