Family Alliance and Intergenerational Transmission of Coparenting in Gay and Heterosexual Single-Father Families through Surrogacy: Associations with Child Attachment Security

Abstract

Parents tend to internalize the coparenting model they experienced during childhood and enact it in their coparenting relationships as adults. These interactive patterns may, in turn, shape their children’s internal working models of attachment relationships. The present study recruited 31 gay and 28 heterosexual single-father families through surrogacy to examine family alliance quality and the mediating role of observed supportive and conflictual coparenting in the association between the coparenting quality single fathers experienced in their families of origin and the attachment security of their children. All single fathers lived in Italy, were cisgender and White, and had a child aged 6–12 years (M = 97.73 months; SD = 20.48; 47.5% girls) who they coparented with non-parental caregivers (i.e., 33 grandparents, 18 babysitters, 8 uncles/aunts). Families did not differ in family alliance dimensions based on fathers’ sexual orientation. Additionally, single fathers who experienced greater coparenting quality in their families of origin demonstrated lower levels of con-flictual coparenting, which, in turn, were associated with greater child attachment security. In con-trast, observed supportive coparenting did not mediate this relation. The results emphasize the need to reconceptualize the dyadic coparental unit in single-father surrogacy families to include extended family members and nonrelatives.
