Objective: This study investigated direct and indirect influences of fathers’ parenting involvement on maternal parenting competence by exploring pathways between fathers’ parenting involvement, maternal inner strength, and maternal parenting competence. Methods: A total of 329 mothers with 3-year-old children responded to online survey questionnaires, which included questions about fathers’ parenting involvement, maternal inner strength, and maternal parenting competence. The data was analyzed by Pearson s correlation coefficients and Structural Equation Modeling. Results: It was observed that maternal inner strength perfectly mediated the association between father s parenting involvement and maternal parenting competence. More concretely, a direct effect of fathers’ parenting involvement on maternal parenting competence was not found. It was also found that fathers’ parenting involvement effects maternal parenting competence indirectly. The effect of fathers’ parenting involvement on maternal inner strength was the greatest among all associations between fathers’ parenting involvement, maternal inner strength, and maternal parenting competence. Conclusion/Implications: These findings have insights for research and practice, which emphasize the important considerations that enhancing maternal inner strength and the power of fathers’ parenting involvement on maternal inner strength should be emphasized in order to improve maternal parenting competence.
