Study Findings
NA = Not available. This means the authors did not report the information in the manuscripts associated with the studies we reviewed.
a This information was not available whenever authors did not report information for the treatment and comparison groups separately on outcome means, standard deviations, and/or sample sizes.
b Authors reported that the program effect (impact) estimate is statistically significant with a p-value of less than 0.05 based on a two-tailed test.
c For some outcomes, having less of that outcome is favorable. In those cases, an effect with a negative sign is favorable to the treatment group (that is, the treatment group had a more favorable outcome than the comparison group, on average).
d An effect shows credibly estimated, statistically significant evidence whenever it has a p-value of less than 0.05 based on a two-tailed test, includes the appropriate adjustment for clustering (if applicable), and it is not based on an endogenous subgroup.
The program was evaluated with a randomized controlled trial involving sexually active girls recruited from youth development centers, adolescent health service centers, and school-based centers in New York. About half the participants were randomly assigned to receive the intervention and half were assigned to a health promotion control condition that received general health information on nutrition, breast health, and anger management. Researchers administered surveys immediately before random assignment (baseline) and at three, six, and 12 months after the intervention.
The study found that six months after the intervention ended, adolescents participating in the intervention reported a significantly lower rate of vaginal sex, a lower frequency of vaginal sex, a lower rate of unprotected vaginal sex, and fewer sexual partners. The study found no statistically significant program impacts on the frequency of unprotected vaginal sex. In addition, the study found no statistically significant program impacts on sexual behavior outcomes at the time of the follow-ups conducted three and 12 months after the intervention ended.
The study also examined program impacts on measures of pregnancy, sexually transmitted infection, and unprotected sex with a 'steady' partner and 'non-steady' partner. Findings for pregnancy and sexually transmitted infection were not considered for this review because the measures were assessed for only about half (51 percent) of the study sample. Findings for the measures of unprotected sex with a steady and non-steady partner were not considered for the review because they fall outside the scope of the review.
