The aim of this study was to examine the relationship between fathers' involvement and maternal gatekeeping, gate-opening, and traditional paternal gender roles, as well as to evaluate fathers' involvement as a mediating role in the relationship between maternal gate-opening, gatekeeping, traditional paternal gender roles, paternal competence, and marital satisfaction. Turkish fathers (N = 239) with a child aged 2-6 years were included in the study. They assessed maternal gatekeeping and gate-opening, their traditional gender roles, parenting competence, and marital satisfaction. Results indicated that fathers' involvement is positively related to maternal gate-opening and negatively associated with traditional paternal gender roles; in addition, fathers' involvement has a mediatory role between maternal gate-opening, traditional paternal gender roles and paternal competence and marital satisfaction. The results suggest that fathers who are involved in their children's lives are more competent and have higher marital satisfaction.
