Resum
Purpose: School-based sex education plays a vital role in the sexual health and well-being of young people. Little is known, however, about the effectiveness of efforts beyond pregnancy and
sexually transmitted disease prevention. The authors conducted a systematic literature review of three decades of research on school-based programs to find evidence for the effectiveness of
comprehensive sex education. Methods: Researchers searched the ERIC, PsycINFO, and MEDLINE. The research team identified
papers meeting the systematic literature review criteria. Of 8,058 relevant articles, 218 met specific review criteria. More than 80% focused solely on pregnancy and disease prevention and were
excluded, leaving 39. In the next phase, researchers expanded criteria to studies outside the U.S. to
identify evidence reflecting the full range of topic areas. Eighty articles constituted the final review. Results: Outcomes include appreciation of sexual diversity, dating and intimate partner violence prevention, development of healthy relationships, prevention of child sex abuse, improved social/
emotional learning, and increased media literacy. Substantial evidence supports sex education
beginning in elementary school, that is scaffolded and of longer duration, as well as LGBTQeinclusive education across the school curriculum and a social justice approach to healthy sexuality.
Conclusions: Review of the literature of the past three decades provides strong support for comprehensive sex education across a range of topics and grade levels. Results provide evidence
for the effectiveness of approaches that address a broad definition of sexual health and take
positive, affirming, inclusive approaches to human sexuality. Findings strengthen justification for
the widespread adoption of the National Sex Education Standards.
