The Title V Abstinence Education block grant administered by the Department of Health and Human Services (HHS) supports this approach. Mathematica Policy Research, Inc. won the contract for the evaluation. The report focuses on four selected Title V abstinence education programs for elementary and middle school students: (1) My Choice, My Future! According to the report:
Findings indicate that youth in the program group were no more likely than control group youth to have abstained from sex and, among those who reported having had sex, they had similar numbers of sexual partners and had initiated sex at the same mean age.... Comprehensive Sexual Education

Advocates of a more comprehensive approach to sex education argue that today's youth need information and decision-making skills to make realistic, practical choices about whether to engage in sexual activities. Many analysts and researchers agree that effective pregnancy prevention programs have many of the following characteristics:
Convince teens that not having sex or that using contraception consistently and carefully is the right thing to do. Actively engage participants and personalize the program information. address peer pressure. While the Bush Administration continues to support an abstinence-only program intervention (with some modifications), others argue that an abstinence message integrated into a comprehensive sex education program that includes information on the use of contraceptives and that enhances decision-making skills is a more effective method to prevent teen pregnancy.
The long-awaited experimentally designed evaluation of abstinence-only education programs, commissioned by Congress in 1997, indicates that young persons who participated in the U.S. Department of Health and Human Services' Title V Abstinence Education block grant program were no more likely than other young persons to abstain from sex. The evaluation conducted by Mathematica Policy, Inc. found that program participants had just as many sexual partners as nonparticipants, had sex at the same median age as nonparticipants, and were just as likely to use contraception as nonparticipants. For many analysts and researchers, the study confirms that a comprehensive sex education curriculum with an abstinence message and information about contraceptives and decision-making skills is a better approach to preventing teen pregnancy. Others maintain that the evaluation examined only four programs for elementary and middle school students, and is thereby inconclusive. Separate experimentally designed evaluations of comprehensive sexual education programs found that some comprehensive programs, including contraception information, decision-making skills, and peer pressure strategies, were successful in delaying sexual activity, improving contraceptive use, and/or preventing teen pregnancy.
