Subjective age and informant-rated cognition and function: A prospective study.

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) 2021 APA, all rights reserved).
