Results reveal that, on eight out of twelve psychometric measures, the risk of clinical emotional problems, developmental problems, or use of mental health treatment services is nearly double among those with same-sex parents when contrasted with children of opposite-sex parents.

The estimate of serious child emotional problems in children with same-sex parents is 17 percent, compared with 7 percent among opposite-sex parents, after adjusting for age, race, gender, and parent’s education and income.
