High-risk children adopted from foster care do equally well when placed with gay, lesbian or heterosexual parents, UCLA psychologists report in the first multi-year study of children adopted by these three groups of parents.
The psychologists looked at 82 high-risk children adopted from foster care in Los Angeles County. Of those children, 60 were placed with heterosexual parents and 22 were placed with gay or lesbian parents (15 with gay male parents and seven with lesbian parents).
The age of the children ranged from 4 months to 8 years, with an average age of 4, while the adoptive parents ranged in age from 30 to 56, with an average age of 41. Sixty-eight percent of the parents were married or living with a partner.
The psychologists studied the children two months, one year and two years after they were placed with a family. The children underwent a cognitive assessment by a clinical psychologist three times during the course of the study, and the parents completed standard questionnaires about the children's behavior at each of the three assessment periods.
The psychologists found very few differences among the children at any of the assessments over the two-year period following placement. On average, children in heterosexual, gay and lesbian households achieved significant gains in their cognitive development, and their levels of behavior problems remained stable. Their IQ scores increased by an average of 10 points, from about 85 to 95 -- a large increase, from low-average to average functioning.
"The children showed meaningful gains in heterosexual, gay and lesbian families," said Justin Lavner, a UCLA doctoral candidate in psychology and lead author of the study. "Their cognitive development improved substantially, while their behavior problems and social development were stable."
The study is published in the October issue of the American Journal of Orthopsychiatry.
The children had multiple risk factors at the time of adoption, including premature birth, prenatal substance exposure, abuse or neglect, and multiple prior placements. The psychologists acquired information regarding these biological and environmental risk factors from birth records, court reports and Los Angeles County Department of Children and Family Services records.
The children adopted by gay and lesbian families had more risk factors at the time of their placement; out of nine risk factors, they averaged one additional risk factor, compared with the children adopted by heterosexual parents.
"The children adopted by gay and lesbian parents had more challenges before they were adopted and yet they end up in the same place, which is impressive," said Letitia Anne Peplau, a distinguished research professor of psychology at UCLA and co-author of the study.
At a time when tens of thousands of foster children lack stable homes and concerns about the suitability of gay and lesbian adoptive parents limit the pool of potential parents, the study indicates that gay and lesbian parents can provide nurturing homes for these children in a manner similar to that of heterosexual parents.
"There is no scientific basis to discriminate against gay and lesbian parents," Peplau said.
Asked whether children need a mother and father, senior author Jill Waterman, a UCLA adjunct professor of psychology, said, "Children need people who love them, regardless of the gender of their parents."
The study participants were recruited from UCLA TIES (Training, Intervention, Education, and Services) for Families as part of a broader study on the development of children adopted from foster care. UCLA TIES for Families promotes the successful adoption of high-risk children from foster care to nurturing homes.
