Details

The program was evaluated using a randomized controlled trial involving adolescents recruited from a family planning clinic in Philadelphia, PA. Study participants were randomly assigned to one of three groups: (1) a treatment group that received the Sisters Saving Sisters intervention, (2) a treatment group that received an informational session on HIV/STD risk reduction without any skill-building activities, or (3) a control group that received a general health promotion program on risk behaviors for cancer, heart disease, and stroke. This report focuses only on the comparison of the group receiving Sisters Saving Sisters versus the health-promotion control group. Surveys were administered before the intervention and at follow- ups conducted 3, 6, and 12 months after the intervention. Biological testing for chlamydia, gonorrhea, and trichomonas was also conducted.

Three months after the intervention the study found no statistically significant program impacts on condom use or number of sexual partners in the past three months. Six months after the intervention the study found no statistically significant program impacts on condom use in the past three months, number of sexual partners in the past three months, or testing positive for chlamydia, gonorrhea, or trichomonas. Twelve months after the intervention adolescents participating in the intervention reported significantly fewer days of sex without condom use in the previous 3 months and significantly fewer sexual partners in the previous 3 months. Adolescents participating in the intervention were significantly less likely to report having had multiple sex partners in the previous 3 months, and were significantly less likely to test positive for gonorrhea, chlamydia, or trichomonas.

The study also examined program impacts on measures of sexual activity while under the influence of drugs or alcohol; STD/HIV knowledge; condom-use knowledge, attitudes, and intentions; impulse control beliefs; and negotiation skill beliefs. Findings for these outcomes were not considered for the review because they fell outside the scope of the review.

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.
