AMSTERDAM — The quality of life of 17-year-olds reared in lesbian-parent families did not differ from that of a matched group of adolescents who grew up in heterosexual-parent families, according to a new study published in the Journal of Developmental and Behavioral Pediatrics.

“Consistently, over the past three decades, researchers have found that the daughters and sons of same-sex parents are psychologically well-adjusted. And now our new data demonstrate that 17-year-olds raised from birth by lesbian mothers are as happy as their peers,” said lead author Loes van Gelderen, MSc, University of Amsterdam.

The study also found, among teens with lesbian mothers, no difference in quality of life based on donor status (whether they had been conceived by known or unknown donors), experienced stigmatization (whether or not they had experienced discrimination), or maternal relationship continuity (whether their mothers were still together or had separated).

“The favorable outcomes for these adolescents are a reflection of good parenting by mothers who prepared their daughters and sons for the prospect of adversity,” said Principal Investigator Nanette Gartrell, MD, of the Williams Institute.

In the study, Quality of Life of Adolescents Raised From Birth by Lesbian Mothers, 78 17-year-olds with lesbian mothers were matched on gender, age, parental education, and ethnic background with adolescents in heterosexual-parent families that were drawn from a representative statewide sample.

The adolescents in both groups gave a numerical score (0 = minimum; 10= maximum) to each of a series of statements such as, “I feel I’m getting along with my parents/guardians,” “I look forward to the future,” and ”I feel good about myself.”

The adolescents with lesbian mothers responded generally in the same way as the teenagers with heterosexual parents.

The data in the new report comes from adolescents whose families are participants in the National Longitudinal Lesbian Family Study (NLLFS), the longest-running and largest prospective investigation of lesbian mothers and their children in the United States.
