The “Emerging Answers 2007: Research Findings on Programs to Reduce Teen
Pregnancy and Sexually Transmitted Diseases
” report is an authoritative and
comprehensive review of research findings on the effectiveness of programs—including
both comprehensive and abstinence-only sex education programs—to reduce teen
pregnancy and sexually transmitted diseases. It was commissioned by the nonpartisan
National Campaign to Prevent Teen and Unplanned Pregnancy and conducted by
Douglas Kirby, Ph.D., a highly regarded researcher with ETR Associates. The report was
also reviewed by an “Effective Programs and Research Task Force” comprised of 13
distinguished and diverse experts.

This report updates two previous studies (conducted in 1997 and 2001) and finds that
“the quality and quantity of evaluation research in this field has improved dramatically
and there is now more persuasive evidence than ever before that a limited number of
programs can delay sexual activity, improve contraceptive use among sexually active
teens, and/or prevent teen pregnancy.”1

Key Findings
There is no evidence base to support continued investments of public funds in
rigid abstinence-only-until-marriage programs.

In sum, studies of abstinence programs have not produced sufficient evidence to
justify their widespread dissemination. … Only when strong evidence demonstrates
that particular programs are effective should they be disseminated more widely
.”1(p. 15)

• To date, no abstinence program of the type eligible for funding under the federal
government’s $176 million abstinence-only-until-marriage program has been found
in a methodologically rigorous study to positively impact teen sexual behavior

At present, there does not exist any strong evidence that any abstinence program
delays the initiation of sex, hastens the return to abstinence, or reduces the number of
sexual partners. In addition, there is strong evidence from multiple randomized trials
demonstrating that some abstinence programs chosen for evaluation because they
were believed to be promising actually had no impact on teen sexual behavior. That 
is, they did not delay the initiation of sex, increase the return to abstinence or
decrease the number of sexual partners
.”1(p. 15)

• In contrast, a substantial majority of the comprehensive sex education programs
—which receive no comparable federal funding—are effective. The
positive outcomes included delaying the initiation of sex, reducing the frequency of
sex, reducing the number of sexual partners and increasing condom or contraceptive

Two-thirds of the 48 comprehensive programs that supported both abstinence and
the use of condoms and contraceptives for sexually active teens had positive
behavioral effects
.”1 (p. 15)

• Comprehensive sex education programs are well suited for widespread replication
and dissemination

When three [comprehensive] programs were replicated with fidelity in different
locations throughout the United States, but in the same type of setting, the original
positive effects were confirmed. This is very encouraging and suggests that effective
programs can remain effective when they are implemented with fidelity by other
people in other communities with similar groups of young people
.”1(p. 16)

Debunking Myths
This report also shows that several myths propagated by advocates of abstinence-only
education are demonstrably false. The report finds that:

Comprehensive sex education does not promote promiscuity.

No comprehensive program hastened the initiation of sex or increased the frequency
of sex
.”1 (p. 16)

Comprehensive sex education does not send a confusing message to adolescents.

Emphasizing both abstinence and protection for those who do have sex is a realistic,
effective approach that does not appear to confuse young people
.”1(p. 16)

• The benefits of comprehensive sex education programs extend to many areas of
decision-making and confidence building among adolescents

Virtually all of the comprehensive programs also had a positive impact on one or
more factors affecting behavior. In particular, they improved factors such as
knowledge about risks and consequences of pregnancy and STD; values and attitudes
about having sex and using condoms or contraception; perception of peer norms
about sex and contraception; confidence in the ability to say ‘no’ to unwanted sex, to 
insist on using condoms or contraception, or to actually use condoms or
contraception; intention to avoid sex or use contraception; and communication with
parents or other adults about these topics. In part by improving these factors, the
programs changed behavior in desired directions
