Abstract: The present research aimed to investigate the associations between solidarity and quality of intergenerational relationships between adult children and their parents and their physical and psychological consequences. In Study 1, latent class analysis on the basis of data from Chinese adult children (N = 1283) shows that six latent solidarity classes emerged, and results of multinomial logistic regression indicate that the characteristics of both generations affect latent solidarity class and relationship quality. In Study 2, data from 367 Chinese intergenerational dyads (adult child-parent, N = 734) were analyzed by actor-partner interaction models, and results indicate that better latent solidarity class (both self and partner) and better relationship quality (self not partner) are associated with both generations’ higher well-being, and better latent solidarity class (both self and partner) and better relationship quality (both self and partner) predict both generations’ lower distress; generation and gender modulate effects of solidarity class and relationship quality on self-rated health and well-being, whereas interaction and similarity between solidarity classes reported by both generations’ also affect well-being and distress.

Key words: intergenerational solidarity, relationship quality, health, well-being, latent class analysis, actor-partner interaction models
