Objective: To explore the effect of co-parenting and father involvement on children’s prosocial behavior. Methods: Using the co-parenting relationship scale, Chinese father parenting investment questionnaire, the strengths and difficulties questionnaire, 488 parents of children aged 3-7 years old were investigated. Results: ①Positive father’s performance in co-parenting had a significant positive effect on children’s prosocial behavior; ②Father’s involvement affected the association between paternal positive co-parenting and children’s prosocial behavior, in other words, when the father was involved more in parenting children, co-parenting had a stronger positive effect on children’s prosocial behavior. Conclusion: Father’s involvement plays a moderating role in the influence of positive paternal co-parenting on children’s prosocial behavior.
