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.

Details
A more recent study by a separate group of researchers evaluated PHAT-AO using a randomized controlled trial that involved 1,319 adolescents attending 6th and 7th grades in public schools in Yonkers, New York. Adolescents participating in the study were randomly assigned either to a treatment group that received the 8-module PHAT-AO program or a control group that received a general health curriculum, the Promoting Health Among Teens! Health Intervention. Surveys were administered before random assignment (baseline), and again three, six, and 12 months after the end of the program.

At each of the three follow-ups, the study found no evidence of statistically significant program impacts on the likelihood of ever having sex among the subgroup of adolescents who were sexually inexperienced at baseline.
