Objective To examine the effect of fatherparenting stress and paternal marital satisfaction on father involvement,and to explore the mediatingrole of maternal perceptions of father involvement in father involvement and maternal marital satisfaction.Methods 300 children's fathers and mothers from 5 kindergartens in Beijing city,Dezhou city,Wuhu city were surveyed with the Chinese version of the PSI/SF,the father involvement questionnaire and the marital satisfactionquestionnaire.Results The score of paternal marital satisfaction was (3.98±0.75),(3.84±0.76) for maternal marital satisfaction,(2.26±0.50) for fatherparenting stress,(2.60±0.49) for father involvement,(2.50±0.50) for maternal perceptions of father involvement.Correlation analysis showed that fatherparenting stress was negatively correlated with father involvement(r=-0.36,P<0.01),paternal marital satisfaction was positively correlated with father involvement (r=0.33,P<0.01),father involvement was positively correlated with maternal marital satisfaction(r=0.36,P <0.01),father involvement was positively correlated with maternal perceptions of father involvement (r=0.48,P<0.01).A structure equation model consisting of fatherparenting stress,father involvement and marital satisfaction had a better degree of fittingGFI =0.99,NFI =0.99,CFI =0.99,RMSEA<0.001.Maternal perceptions of father involvement mediated the effect of father involvement on maternal marital satisfaction (effect value0.41,P<0.05).Conclusion Fatherparenting stress and paternal marital satisfaction could significantly predict father involvement,father involvement could significantly predict maternal marital satisfaction.These studies verified the spillover effect and the crossover effect between spousal subsystem and parental subsystem.
