A new study, published in the journal Child Development, suggests that for adoptive couples, the extent to which they work together and support each other is more important than their sexual orientation.
The study observations confirmed this pattern—lesbian and gay parents participated more equally than heterosexual parents during family interaction. Lesbian couples showed the most supportive and least undermining behavior, whereas gay couples showed the least supportive behavior, and heterosexual couples the most undermining behavior.
Overall, supportive coparenting was associated with better child adjustment.
