 The study found that community-based home elderly care services can improve the social participation of chronically ill elderly people. The results showed that these services had an asymmetrical impact on the social participation of the chronically ill elderly, with more positive effects on voluntary participation and political participation than negative effects on economic participation. Additionally, the study also revealed that the services had a tendency to reduce economic participation and increase voluntary participation and political participation overall. Furthermore, the study found that the services had an asymmetric impact on various social participation of the chronically ill elderly through the multidimensional health mediation mechanism.
