Details

The program's evidence of effectiveness was first established in a randomized controlled trial involving Latino adolescents recruited from three neighborhood high schools and community-based organizations in Philadelphia. About half the study participants were randomly selected for a treatment group that was offered the eight-hour intervention over two consecutive Saturdays. The other participants were assigned to a control group that received a general health promotion curriculum on diet, exercise, and substance use. Surveys were administered immediately before the program (baseline), immediately after the program, and three, six and 12 months after the program ended.

The study found that, averaged across all follow-up periods, adolescents in the intervention group were significantly less likely to report having had sexual intercourse and having had multiple sexual partners in the past three months, and reported significantly fewer days of unprotected sex. Adolescents in the intervention group were also more likely to report consistent condom use. The study found no statistically significant program impacts on condom use at last sex or the proportion of days of condom-protected sex.

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.
