Abstract: ObjectivesBased on the “linked lives” tenant of the life course perspective, this longitudinal study aims to examine the actor and partner effects of social participation on cognitive function in older Chinese couples.MethodsA total of 1,706 couples aged 60 and older were included in the final analyses. Social participation was measured using 2 questions regarding types of activities and frequency. Cognitive function was measured using a combination of memory, orientation, visuoconstruction, attention, and calculation. The lagged-dependent APIM was used to model the dyadic associations between social participation and cognitive function.ResultsThe time-averaged actor effects of both husbands’ and wives’ social participation on their own cognitive function were significant (p .05 for all).DiscussionOur findings indicate an asymmetrical pattern of actor–partner interdependence, where husbands’ social participation may affect their wives’ cognitive function on average, but wives’ social participation does not affect their husbands’ cognitive function. Clinical practitioners should invite both partners, especially husbands, to participate in social participation interventions to facilitate crossover benefits for wives. Moreover, policymakers should build more facilities to encourage older couples to engage in social activities to prevent cognitive decline.
