Details

The program was evaluated in a cluster randomized controlled trial involving adolescents from 15 low-income housing developments in three states. Across the three states, five housing developments were randomly selected to implement the full intervention, five were randomly selected to implement only the adolescent workshops (with no community-level intervention), and five were randomly selected for a control group that was offered a one-time informational session on AIDS education. Surveys were administered before the intervention and at follow-ups conducted 3 and 12 months after the adolescent workshops.

The study found that 12 months after the workshops ended, adolescents participating in the intervention who were sexually inexperienced at baseline were significantly more likely to report having remained abstinent. The study found no statistically significant program impacts at the time of the 3-month follow-up survey.

The study also examined program impacts on measures of condom use. Findings for this outcome were not considered for the review because they did not meet the review evidence standards. Specifically, findings were reported only for subgroups of youth defined by sexual activity at follow-up.

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.
