### Study Findings

The program's evidence of effectiveness was first established in a cluster randomized controlled trial involving 24 alternative high schools in four large urban counties in northern California. Thirteen schools were randomly selected for a treatment group that implemented the program and eleven schools were selected for a control group not offered the program. Surveys were administered immediately before the program started (baseline) and again six, 12, and 18 months after baseline.The study found that six months after the baseline survey, students in the treatment schools reported a significantly lower frequency of sexual intercourse and lower frequency of intercourse without a condom in the previous three months, and were significantly more likely to report using a condom at last intercourse. The study found no statistically significant impacts on the number of sexual partners in the previous three months, on two measures of contraceptive use (number of partners without a condom in the previous three months, and use of effective pregnancy prevention method at last intercourse), and on initiation of sexual intercourse (among sexually inexperienced at baseline). For the 12- and 18-month follow-up surveys, the study found no statistically significant impacts on any of these outcomes.The study also examined program impacts on measures of HIV and condom knowledge, self-efficacy, attitudes, beliefs, and intentions. 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 meets the review standards for credible evidence whenever it is statistically significant with 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.
