San Francisco, CA - The Williams Institute, a research center on sexual orientation law and public policy at UCLA School of Law, announces a new report from the U.S. National Longitudinal Lesbian Family Study (NLLFS) published in Pediatrics. The U.S. NLLFS -the longest-running study ever conducted on American lesbian families-found that the 17-year-old adolescent daughters and sons of lesbian mothers, all conceived through donor insemination, were rated higher than their peers in social, academic, and overall competence, and lower in aggressive behavior, rule-breaking, and social problems, on standardized assessments of psychological adjustment.
