Researchers looked at information gleaned from 15 studies on more than 500 children, evaluating possible stigma, teasing and social isolation, adjustment and self-esteem, opposite gender role models, sexual orientation, and strengths.
Studies from 1981 to 1994, including 260 children reared by either heterosexual mothers or same-sex mothers after divorce, found no differences in intelligence, type or prevalence of psychiatric disorders, self-esteem, well-being, peer relationships, couple relationships, or parental stress.
"Some studies showed that single heterosexual parents' children have more difficulties than children who have parents of the same sex," Perrin says. "They did better in discipline, self-esteem, and had less psychosocial difficulties at home and at school."
