PROGRAM EFFICACY

A lot of research has been done to determine what works when it comes to helping young people adopt protective behaviors such as delaying sexual behavior or using condoms and contraception. This section provides information on the research that has been done on programs designed to educate young people about sexuality, prevent sexually transmitted diseases (STDs), and avoid unintended pregnancy. The research included on this page shows that comprehensive sexuality education works while abstinence-only-until-marriage program have never been proven effective.

This section is divided into four parts comprehensive education about sexuality, abstinence-only-until-marriage programs, what young people are learning, and additional evaluation resources.

COMPREHENSIVE EDUCATION ABOUT SEXUALITY

Numerous studies and evaluations published in peer-reviewed literature have looked at sexuality education programs.  Studies have shown that comprehensive education about sexuality, programs that teach teens about both abstinence and contraception/ disease prevention, are an effective strategy to help young people delay their initiation of sexual intercourse, reduce the number of sexual partners they have,  and increase condom or contraceptive use when they do become pregnant.  

EVALUATIONS

The studies listed in this section are reviews of evaluations of interventions designed to prevent HIV, other STDs, and teen pregnancy. 

Sex and HIV Education Programs for Youth: Their Impact and Important Characteristics

Source: Doug Kirby, et. al., Sex and HIV Education Programs for Youth: Their Impact and Important Characteristics (Scotts Valley, CA: ETR Associates, 2006).

Description:  The researchers gathered information on 83 different studies of effective education programs that showed an ability to reduce risks for HIV, other STDs, or unintended pregnancy. Of the 83 studies reviewed, 56 were based in the United States. Programs targeted young people ages 9–24. 

Key Findings:

  • Of the 52 studies that measured impact on the initiation of sex, 22 (42 %) found that the programs significantly delayed the initiation of sex among one or more groups for at least six months, 29 (55%) found no significant impact, and one (in the United States) found the program hastened the initiation of sex.
  • Of the 54 studies measuring program impact on condom use, almost half (48%) showed increased condom use; none found decreased condom use.
  • Of the 13 studies that measured pregnancy rates, three found significant positive effects, nine found insignificant effects, and one (in the United States) found significant negative effects.
  • Of the 10 studies that measured impact on STI rates, two found a positive impact, six found no significant impact, and two found a negative impact.
  • Based on these finding the researchers identified 17 characteristics of effective programs.

Emerging Answers: Research Findings on Programs to Reduce Teen Pregnancy

Source:  Doug Kirby, Emerging Answers: Research Findings on Programs to Reduce Teen Pregnancy (Washington, DC: National Campaign to Prevent Teen Pregnancy, 2001). 

Description: The National Campaign to Prevent Teen Pregnancy commissioned a review of programs considered effective at reducing teen pregnancy and/or STD rates among young people. Kirby gathered information on over 250 studies to identify the elements that made the programs effective.

Key Findings:

  • Research clearly shows that comprehensive education about sexuality does not hasten the onset of sex, increase the frequency of sex, or increase the number of sexual partners teens have.
  • Research shows that some sexuality and HIV education programs can delay the onset of sex, reduce the frequency of sex, or reduce the number of sexual partners.
  • Research on abstinence-only-until-marriage programs, however, remains inconclusive. This report identified several programs that had proven ability to delay sex or increase condom or other contraceptive use, thereby decreasing unprotected sex. Among these were:

    • Reducing the Risk
    • Safer Choices
    • Becoming a Responsible Teen
    • Making a Difference: An Abstinence Approach to STD, Teen Pregnancy, and HIV/AIDS Prevention
    • Making a Difference: A Safer Sex Approach to STD, Teen Pregnancy, and HIV/AIDS Prevention

Description: Researchers from the Centers for Disease Control and Prevention reviewed U.S.-based HIV-prevention research literature from 2000 through 2004 to identify interventions demonstrating best evidence of efficacy for reducing HIV risk. They found eighteen interventions that met the criteria for “best evidence.”

Key Findings:

  • Results of these interventions included increased condom use and reductions in unprotected sexual intercourse, number of sexual partners, injection drug use or needle sharing, and newly acquired sexually transmitted infections.
  • None of the “best evidence” programs were based on abstinence-only-until-marriage.

A Decade in Review: Building on the Experiences of Past Adolescent STI/HIV Interventions to Optimize Future Prevention Efforts

Source:  J.M. Sales, et. al., “A decade in review: Building on the experiences of past adolescent STI/HIV interventions to optimize future prevention efforts,” Sexually Transmitted Infections 82 (2006): 431-436.

Description:  Researchers reviewed findings from selected adolescent STD/HIV interventions in the United States between 1994 and 2004. They examined the most current STD risk reduction programs in a wide range of settings: communities, schools, clinics, detention homes, and drug treatment facilities. They then identified the features that were associated with effective programs.

Key Findings:

  • The risk behavior most susceptible to change was condom use during vaginal sex.
  • Researchers concluded that to be most effective at reducing risk, programs should educate teens on correct condom use and other behaviors that have been proven most likely to change.

ABSTINENCE-ONLY-UNTIL-MARRIAGE-PROGRAMS

Abstinence-only-until-marriage programs have gained popularity in recent years in large part because the federal government continues to sink over $170 million each year into such programs.  These programs have never been proven effective and often rely on fear, shame, and misinformation.  In addition, virginity pledges, a cornerstone of many of these programs, have been shown to be ineffective at best and possibly harmful. 

ANALYZING DEFINITIONS AND CURRICULA

As abstinence-only-until-marriage programs have gained popularity many new curricula and resources have been created.  A number of researchers and organizations have reviewed these materials and found that they rely on fear and shame, include medical inaccuracies, and are inconsistent in their definitions of abstinence.  In addition to the resources listed in this section, see  SIECUS’ reviews of some of the more popular abstinence-only-until-marriage curricula at http://www.communityactionkit.org/curricula_reviews.html

A Review of 21 Curricula for Abstinence-Only-Until-Marriage Programs

Source:  K.I. Wilson, et. al., “A review of 21 curricula for abstinence-only-until-marriage programs,” Journal of School Health 75(3): 90–98 (2005).

Description:  The researchers reviewed 21 curricula for abstinence-only-until-marriage programs used in middle school grades (fifth to eighth) or with middle school-aged audiences (ages 9–13). 

Key Findings:Abstinence materials were found to “vary considerably” in terms of overall quality.
The researchers suggested that many of these materials are better suited for “character education” than sexuality education.

Description:  The researchers evaluated how program directors, instructors, and teens in eight Texas abstinence-only-until-marriage education programs define the term “abstinence.”

Key Findings:

  • There was “substantial variability” in how the term “abstinence” was defined.
  • Researchers concluded that “…many of the programs awarded federal funding for abstinence education are not sex education programs.”

The Waxman Report

Source:Prepared for Rep. Henry A. Waxman, The Content of Federally Funded Abstinence-Only Education Programs (Washington, DC: United States House of Representatives, Committee on Government Reform, Minority Staff, Special Investigations Division, 2004). 

Description: This Congressional report prepared for Representative Henry Waxman (D-California) found that widely used federally funded abstinence-only curricula distort information, misrepresent the facts, and promote gender stereotypes.

Key Findings:

  • More than 80 percent of the abstinence-only curricula reviewed contain false, misleading, or distorted information about reproductive health.
  • The curricula reviewed misrepresent the effectiveness of contraceptives in preventing STDs and unintended pregnancy.
  • The curricula reviewed contain false information about the risks of abortion, blur religion and science, promote gender stereotypes, and contain basic scientific errors.

Description:  In 2006, the Federal Government Accountability Office (GAO) concluded that government-approved evaluations of abstinence-only programs fail to follow scientific guidelines.

Key Findings:

  • The Department of Health and Human Services (HHS) is not providing adequate oversight of federally funded abstinence-only-until-marriage programs. 
  • In particular, HHS is not reviewing material for scientific/medical accuracy nor is it requiring grantees to do so.

The Mathematica Report

Source:  The Evaluation of Abstinence Education Programs Funded Under Title V Section 510: Interim Report (Washington, D.C.: Mathematica Policy Research, Inc., 2005).

Description:  Mathematica has been hired by the federal government to conduct an evaluation of programs funded under the Title V Welfare Reform funding stream.  Of the more than 700 federally funded abstinence-only programs, the interim evaluation looked at 11 programs, only four of which were evaluated for attitudinal impact. The other six programs evaluated are community-wide interventions and were reviewed for implementation and process analysis only. None was evaluated for behavioral impact.

Key Findings:

  • The interim report measured only the ability of the evaluated programs to “strengthen knowledge and attitudes supportive of abstinence” and whether they “induce[d] more youth to embrace abstinence from sexual activity as a personal goal.”
  • The interim evaluation found that while there was some support for the idea of abstinence, the programs had little impact on peer pressure and no impact on views of marriage, expectation to abstain, self-esteem, self-efficacy, self-control, refusal skills, or communication with parents.

VIRGINITY PLEDGES

Although they were once the sole province of religious organizations, many secular groups and schools now host events where students sign “virginity pledges” as a way to promote pre-marital abstinence. Today, virginity pledges are also part of most abstinence-only-until-marriage curricula and programs. Research has found these pledges to be ineffective and potentially harmful.

Promising the Future: Virginity Pledges and the Transition to First Intercourse

Source: Peter Bearman and Hanah Brückner, “Promising the Future: Virginity Pledges and the Transition to First Intercourse,” American Journal of Sociology 106.4 (2001): 859-912.

Description:  Researchers used data from the National Longitudinal Study of Adolescent Health, a nationally representative study of students enrolled in grades 7–12 in 1995, to determine the impact of virginity pledges on young people’s sexual behavior.  

Key Findings:

  • Under certain conditions these pledges may help some adolescents delay sexual intercourse. When they work, pledges help this select group of adolescents delay the onset of sexual intercourse for an average of 18 months—far short of marriage.

  • 88% of young people who take virginity pledges have sexual intercourse before marriage.

  • Young people who took a pledge were one-third less likely to use contraception when they did become sexually active than their peers who had not pledged.

  • Pledges taken by entire classes were ineffective.

Description:Researchers used data from the National Longitudinal Study of Adolescent Health, a nationally representative study of students enrolled in grades 7–12 in 1995, to determine how virginity pledges impacted the rates of sexually transmitted diseases among young people who took them.  

Key Findings:

  • Although some students who take pledges delay intercourse, ultimately they are equally as likely to contract an STD as their non-pledging peers.

WHAT YOUNG PEOPLE ARE LEARNING

This study looks at what young people are learning in the classroom and how this has changed over the years.

Changes in Formal Sex Education: 1995–2002

Source:  L. D. Lindberg, et. al., LD, “Changes in formal sex education: 1995–2002,” Perspectives on Sexual and Reproductive Health 38(4) (2006): 182-189.

Description: The researchers used data from the 1995 National Survey of Adolescent Males, the 1995 National Survey of Family Growth (NSFG), and the 2002 NSFG, to examine changes in male and female adolescents’ reports of the sex education they have received from formal sources.

Key Findings:

  • The researchers found that nationally, in 2002 a lower proportion of teenagers received formal education about birth control methods than in 1995 (for males, the proportion declined from 81% to 66%; for females, the proportion declined from 87% to 70%).
  • They concluded that the “shift away from teaching teenagers about birth control methods as part of their formal instruction has occurred without firm evidence documenting the positive effects of abstinence only instruction.”
