- Only 1 abstinence-only education program has been experimentally evaluated (Postponing Sexual Involvement/ ENABL) and it showed no impact on the number of sexual partners. Few strong evaluations of abstinence-only programs have been conducted. Future evaluations will assess the effectiveness of these programs.

- The two clinic-based programs that examined number of sexual partners showed no impacts (ASSESS and DeLameter et al. 2000 in Milwaukee, WI).

- Out of the 2 sexuality education programs that experimentally measured the number of sexual partners as an outcome, neither had an impact (Project SNAPP) and Safer Choices.

- Of the 4 HIV/AIDS experimental education programs that measured the number of sexual partners as an outcome, 1 showed positive impacts (Becoming a Responsible Teen). The other 3 programs had no impact (Be Proud, Be Responsible; YAPP; and Gilmore et al. 1997 in Seattle, WA ).

- Focus on delaying age of sexual debut.

- Reduce other risky behaviors, such as substance abuse.

- Promote girls' participation in sports

- Convey to parents the importance of talking to teens about HIV and expressing disapproval of teen sexual activity.

- Advocate strong parental monitoring.

- Reduce the occurrence of non-voluntary sexual experiences.

- Encourage teens to form friendships with peers who are not sexually experienced.

- Sexuality education and HIV education programs that include 10 components were associated with more positive outcomes (Kirby, 2001).

- Sexuality or HIV education programs that did not include the 10 components listed above, including programs that were primarily didactic and that did not include teen involvement, were not associated with a reduced frequency of sexual activity. Programs short in duration appear to have no association with outcomes.
