Abstract：
A greater number of studies have examined the impact of social engagement on cognitive function rather than the other way around, leaving their reciprocal association underexplored. Furthermore, formal and informal social engagement are not differentiated, although they may have independent relationships with cognitive function. This study aims to identify (1) whether informal and formal social engagements are effective in maintaining cognitive health and (2) if cognitive function has a bidirectional effect on social engagement. The study applies a dynamic panel data structural equation modeling with a maximum likelihood estimator (ML-SEM) to the Korean Longitudinal Study of Aging (KLoSA) data. The results confirm that frequent participation in organizational activities is more robustly associated with cognitive function than memberships or informal social contact. Concerning the bidirectional relationship, the cognitive function increases the degrees of informal and formal engagement. The study thus validates a reciprocal association between social engagement and cognitive function.
摘要：
更多的研究已经研究了社会参与对认知功能的影响，而不是相反，留下他们的互惠协会。此外，正式和非正式的社会参与没有区别，尽管它们可能与认知功能有独立的关系。这项研究旨在确定（1）非正式和正式的社会参与是否有效维持认知健康，以及（2）认知功能是否对社会参与有双向影响。该研究将具有最大似然估计器（ML-SEM）的动态面板数据结构方程模型应用于韩国纵向衰老研究（KLoSA）数据。结果证实，与成员或非正式社会接触相比，频繁参与组织活动与认知功能的关系更为紧密。关于双向关系，认知功能增加了非正式和正式参与的程度。因此，该研究验证了社交参与与认知功能之间的相互关联。
