Bidirectional longitudinal relationships between parents' positive co-parenting, marital satisfaction, and parental involvement.

Numerous studies have shown that co-parenting plays an important role in marital and parent-child interactions. However, little is known about the bidirectional associations between positive co-parenting and marital and parent-child factors, as well as the dynamic underlying mechanisms. This study used cross-lagged panel model (CLPM) to explore the bidirectional longitudinal relationship between positive co-parenting, marital satisfaction, and parental involvement among Chinese parents from a positive family multiple systems perspective. A sample of 668 father-mother dyads (father's M age = 36.47, SD age = 5.34; mother's M age = 35.45, SD age = 5.07) completed a series of questionnaires at three time points (approximately spaced 1 year between each time point). The results showed that positive co-parenting positively predicted marital satisfaction and parental involvement and that marital satisfaction positively influenced parents' positive co-parenting, whereas the effect of parental involvement on positive co-parenting was significant among fathers. Additionally, fathers' marital satisfaction can affect their involvement, but this effect is negligible among mothers. Finally, parental marital satisfaction mediated the relationship between positive co-parenting and the next stage of positive co-parenting. This study provided new ideas and interventions to strengthen family cohesion and harmony. [ABSTRACT FROM AUTHOR]
