According to a study by Charlotte J. Patterson, a professor of psychology at the University of Virginia in Charlottesville:
Adolescents who have two moms as parents are no different from teens growing up with a mother and a father, a new study finds.
On measures of psychosocial well-being, school functioning, and romantic relationships and behaviors, the teens with same-sex parents were as well adjusted as their peers with opposite-sex parents. The authors found very few differences between the two groups. A more important predictor of teens’ psychological and social adjustment, they found, is the quality of the relationships they have with their parents.
