Study Findings
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.
During the 12-month follow-up period, 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.
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.
