The program’s evidence of effectiveness was first established in a randomized controlled trial involving sexually active African American females recruited from four community health agencies in the southern United States. Study participants were randomly assigned to either a treatment group that received the intervention or a control group that received a general health promotion intervention on nutrition and exercise. Surveys were administered immediately before the intervention and at follow- ups conducted 6 and 12 months after the intervention. Biological testing for chlamydia, gonorrhea, and trichomonas was also conducted.

The study found that six months after the intervention, adolescents participating in the intervention were significantly less likely to report having a pregnancy and significantly more likely to report consistent condom use in the past 6 months. Adolescents participating in the intervention were significantly more likely to report having used a condom during last sex, reported a significantly higher percentage of condom-protected sexual intercourse acts during both the past 30 days and the past 6 months, were less likely to have had a new vaginal sex partner in the last 30 days, and reported significantly fewer episodes of unprotected sexual intercourse during both the past 30 days and the past 6 months. The study found no statistically significant impacts on self-reported condom use in the past 30 days.

The study found that twelve months after the intervention, adolescents participating in the intervention were significantly more likely to report consistent condom use in the both the past 30 days and the past 6 months. Adolescents participating in the intervention were significantly more likely to report using a condom during last sex, reported a significantly higher percentage of condom-protected sexual intercourse acts during both the past 30 days and the past 6 months, and reported significantly fewer episodes of unprotected sexual intercourse during both the past 30 days and the past 6 months. The study found no statistically significant program impacts on self-reported pregnancy in the past 6 months.

Across the two follow-up periods, adolescents participating in the intervention were significantly less likely to have a chlamydia infection. The study found no statistically significant program impacts on gonorrhea or trichomonas infections.

This randomized controlled trial received a low rating because it had high attrition and did not establish baseline equivalence for the final analysis sample.

This study evaluated an adapted version of the SiHLE program with a randomized controlled trial involving African American female adolescents in the San Francisco Bay Area. The adapted “Multimedia” version of the program comprised two one-hour sessions delivered individually by computer. Study participants were randomly assigned to either a treatment group that received the intervention or to a control group that received a general health education session. Surveys were administered immediately before random assignment (baseline) and three months after baseline.

The study examined changes in rates of sexual risk behaviors between the baseline and three-month follow-up surveys. However, the study did not test for differences in these outcomes between the treatment and control groups. The study also examined measures of condom-use self-efficacy, knowledge, sexual-communication self-efficacy. Findings for these outcomes were not considered for the review because they fell outside the review of the review.

This study did not meet the review eligibility criteria.

Notes

Some study entries may include more than one citation because each citation examines a different follow-up period from the same study sample, or because each citation examines a different set of outcome measures on the same study sample. A blank cell indicates the study did not examine any outcome measures within the particular outcome domain or the findings for the outcome measures within that domain did not meet the review evidence standards.

Information on evidence of effectiveness is available only for studies that received a high or moderate rating. Read the description of the review process for more information on how these programs are identified.
