Abstract

The study aimed to investigate the reciprocal longitudinal relationship between social activity participation and cognitive function. The uniqueness of the current study is in its investigation on the simultaneous reciprocal relationship between social activity participation and cognitive function, which differs from previous studies examining the unidirectional relationship. Participants were 10,254 individuals aged 45 and over who participated in the Korean Longitudinal Study of Aging.
The results are as follows: First, multivariate latent growth curve model identified the reciprocal longitudinal relationship between social activity participation and cognitive function. The baseline social activity participation had a significant effect on the rate of change in cognitive function, and the baseline cognitive function had a significant impact on the rate of change in social activity participation. These findings support a probability of cyclical directionality that high levels of cognitive function lead to high levels of social activity participation, which in turn maintain or raise cognitive function. Second, socioeconomic status was a risk factor to social activity participation as well as to cognitive function. This suggests that individuals with lower levels of education and lower incomes are less likely than others to participate in social activity, and this leads to a negative effect on the cognitive function. Based on these findings, implications for theory and practice are discussed.
