Objectives. This study evaluated the long-term effectivenessof Draw the Line/Respect the Line, a theoretically based curriculumdesigned to reduce sexual risk behaviors among middle schooladolescents.
Methods. The randomized controlled trial involved 19 schoolsin northern California. A cohort of 2829 sixth graders was trackedfor 36 months.
Results. The intervention delayed sexual initiation among boys,but not girls. Boys in the intervention condition also exhibitedsignificantly greater knowledge than control students, perceivedfewer peer norms supporting sexual intercourse, had more positiveattitudes toward not having sex, had stronger sexual limits,and were less likely to be in situations that could lead tosexual behaviors. Psychosocial effects for girls were limited.
Conclusions. The program was effective for boys, but not forgirls.
