A mixed-method design was employed. Two hundred Turkish women (Mage = 33.04) participated in online surveys (N = 200), and ten women (N = 10) participated in focus groups. Participants completed a demographic information form and three inventories. The SPSS macro PROCESS with Model 4 was run to test the hypothesis that the relationship between maternal warmth and maternal gate closing is mediated by traditional motherhood in survey data. Results revealed that maternal warmth significantly and positively predicted traditional motherhood (B =.45, SE =.094, p <.001, 95% CI = [.27,.64]), which in turn significantly and positively predicted maternal gate closing (B =.09, SE =.02, p <.01, 95% CI = [.04,.14]). The indirect association between maternal warmth and maternal gate closing was significant in positive direction (B =.0420, boot SE =.0023, 95% CI = [.02,.07]). Focus group results revealed that childrearing tasks were predominantly performed by mothers who want to be first person responsible for these tasks since fathers were perceived as unskillful or withdrawn. The results highlight the importance of determinants of maternal gate closing for intervention programs targeting coparenting and involvement of fathers in the prenatal and postpartum periods.
