ABSTRACT

Executive function and episodic memory processes are particularly vulnerable to aging. We sought to learn the degree to which sex, mood, and subjective sleep quality might be related to executive function and episodic memory composite scores in community-dwelling older adults. We replicated Glisky and colleagues’ two-factor (i.e., executive function [N=263] versus episodic memory [N=151]) structure, and found that it did not significantly differ between males and females. Moderation analyses revealed no interactions between sex, mood, and sleep in predicting either composite score. However, females significantly outperformed males on the episodic memory composite, and on all the individual tests comprising it. Ours is the first study to look at sex differences in this battery’s factor structure and its potential relations with mood and sleep. Future longitudinal studies in both healthy and clinical populations will help us further probe the possible influence of these variables on executive function and episodic memory in aging.

 抽象的

执行功能和情景记忆过程特别容易受到衰老的影响。我们试图了解社区老年人的性别、情绪和主观睡眠质量与执行功能和情景记忆综合得分的相关程度。我们复制了 Glisky 和同事的双因素（即执行功能 [N=263] 与情景记忆 [N=151]）结构，发现男性和女性之间没有显着差异。调节分析显示，性别、情绪和睡眠之间在预测任一综合得分时没有相互作用。然而，在情景记忆综合以及包含它的所有个人测试中，女性的表现明显优于男性。我们的研究是第一项研究该电池因子结构的性别差异及其与情绪和睡眠的潜在关系的研究。未来对健康和临床人群的纵向研究将帮助我们进一步探讨这些变量对衰老过程中执行功能和情景记忆的可能影响。
