The current study examined bidirectional relationships between well-being and cognitive function using up to 10 annual assessments ( 5.67, 3.43) of different types of well-being and a comprehensive cognitive battery from a sample of older adults living in the Chicago metropolitan area ( = 1,702; mean age = 81.07 years, = 8.04; 75.1% White Americans, 23.9% Black Americans). Bivariate latent growth curve models indicated older adults who started out with better well-being also had better cognitive function, and sharper decreases in well-being were associated with sharper declines in cognitive function. Random-intercept cross-lagged panel models indicated older adults with better well-being on average had better cognitive function on average. Further, well-being change at one time point predicted subsequent cognitive change and vice versa. These findings were stronger for eudaimonic well-being and sense of purpose than for life satisfaction. Findings highlight the role of well-being in the goal to combat cognitive decline, as well as the importance of supporting well-being in individuals experiencing cognitive decline.
本研究使用对不同类型幸福感的多达10次年度评估（5.67次，3.43次）以及一套综合认知测试组，对居住在芝加哥大都市地区的老年人样本（n = 1702；平均年龄 = 81.07岁，标准差 = 8.04；75.1%为美国白人，23.9%为美国黑人）的幸福感与认知功能之间的双向关系进行了研究。双变量潜在增长曲线模型表明，初始幸福感较好的老年人认知功能也较好，幸福感的急剧下降与认知功能的急剧衰退相关。随机截距交叉滞后面板模型表明，平均而言，幸福感较好的老年人平均认知功能也较好。此外，一个时间点的幸福感变化预测了随后的认知变化，反之亦然。这些发现对于实现幸福和目标感而言比生活满意度更为显著。研究结果突出了幸福感在对抗认知衰退目标中的作用，以及在经历认知衰退的个体中支持幸福感的重要性。
