While adopted children are at higher risk of emotional problems overall, being adopted did not account for the differences between children in same-sex and opposite-sex households.
It’s also worth noting that while being bullied clearly aggravates emotional health, there was no difference in self-reported experience of having been bullied between the children of same-sex and opposite-sex parents.
Vocal critics, soon to emerge, will likely home in on the explanatory mechanism—the fact that two mothers or two fathers can’t possibly both enjoy a biological connection to a child—in suggesting the results of the study reveal nothing of value about same-sex households with children. On the contrary, the study reveals a great deal. Namely, there is no equivalent replacement for the enduring gift to a child that a married biological mother and father offer. It’s no guarantee of success. It’s not always possible. But the odds of emotional struggle at least double without it. Some critics might attribute the emotional health differences to the realities of “adoption by strangers,” but the vast majority of same-sex couples in the NHIS exhibited one parent with a biological relationship with the child.
Even research on “planned” same-sex families—those created using assisted reproductive technology (ART)—reveals the significance of biological ties. Sullins notes such studies
have long recognized that the lack of conjoined biological ties creates unique difficulties and relational stresses. The birth and non-birth mother . . . are subject to competition, rivalry, and jealousy regarding conception and mothering roles that are never faced by conceiving opposite-sex couples, and which, for the children involved, can result in anxiety over their security and identity.
The population-based study pooled over 2,700 same-sex couples, defined as “those persons whose reported spouse or cohabiting partner was of the same sex as themselves.” This is a measure similar to that employed in the US Census, but it has the advantage of clarity about the sexual or romantic nature of the partnership (being sure to exclude those who are simply same-sex roommates). Among these, 582 had children under 18 in the household. A battery of questions was completed by 512 of them.
