Abstract

Background: Mastery may shape the way individuals cope with life challenges and influence cognitive function in later life. Mastery grows out of traumatic experience and could change over the life course. This study examined the within-person and between-person associations of mastery and cognitive function, and if these associations were moderated by age in the United States.

Method: Data were derived from three time points (2006-2008, 2010-2012, and 2014-2016) of the Health and Retirement Study, with 14,461 adults (aged 51 or above). Cognitive function was measured through a 27-point Telephone Interview Cognitive Screen (TICS). Mastery was measured by a modified Pearlin Mastery Scale. Multilevel modeling was employed to analyze the data.

Results: Both within-person ( $β$ =0.124, SE = 0.023, p < 0.001) and between-person ( $β$ =0.089, SE = 0.029, p = 0.002) mastery were significantly associated with cognitive function. Older adults with higher between-person mastery tended to have slower cognitive decline ( $β$ =0.063, SE = 0.021, p < 0.001). Moreover, age moderated the within-person ( $β$ =0.013, SE = 0.003, p < 0.001) associations between mastery and cognition with a stronger association observed among individuals with older age.

Conclusions: The current study provides evidence for within-person and between-person associations between mastery and global cognition in the United States as well as the moderating role of age. The design of the current study did not directly assess the causal direction between mastery and cognitive function. Future studies could test the directionality of associations between mastery and cognitive function.

分解掌握程度与认知功能的人际关联和人内关联：年龄是调节因素。

背景：掌握可能会塑造个人应对生活挑战的方式，并影响其日后的认知功能。掌握感源于创伤经历，并可能随生命历程而改变。本研究探讨了掌握程度与认知功能之间的人内和人际关联，以及这些关联是否会受到美国人年龄的影响：数据来源于《健康与退休研究》的三个时间点（2006-2008 年、2010-2012 年和 2014-2016 年），涉及 14,461 名成年人（51 岁或以上）。认知功能通过 27 点电话访谈认知筛查（TICS）进行测量。掌握程度通过改良的皮尔林掌握程度量表进行测量。采用多层次模型对数据进行分析：人与人之间 ( β =0.124, SE = 0.023, p β =0.089, SE = 0.029, p = 0.002) 的掌握程度与认知功能有显著相关性。人与人之间掌握程度较高的老年人认知功能衰退的速度往往较慢（β =0.063, SE = 0.021, p β =0.013, SE = 0.003, p 结论：本研究为美国人的掌握程度和全球认知之间的人内和人际关联以及年龄的调节作用提供了证据。本研究的设计没有直接评估掌握程度与认知功能之间的因果关系。未来的研究可以检验掌握程度与认知功能之间的关联的方向性。
