CHANGE IN EPISODIC MEMORY AND EXECUTIVE FUNCTIONING PREDICTS MORTALITY RISK

The current study explored whether the Brief Test of Adult Cognition via Telephone (BTACT) assessment could be used to predict longevity in a national sample of adults from the Midlife Development in the United States (MIDUS) study. Specifically, we examined whether 9-year changes in episodic memory (EM) and executive functioning (EF) predicted all-cause mortality risk (2004-2018). The sample included 2,643 participants (MAge=45.87; 92.23% white; 107 deceased) who completed the BTACT twice: between 2004-06 and between 2013-2017. Using change scores, decreases in EM (HR= 1.45 [1.09-1.93], p=.01) and EF (HR=1.585 [1.17-2.14], p<.001) increased the hazard of dying (controlling for age, gender, race, education, and self-rated health). Results suggest the BTACT is sensitive enough to detect health-consequential decreases in EM/EF. Future research should consider the BTACT as a viable assessment tool for older adults who may not have easy access to cognitive screenings.
