Study Findings
![Potentially favorable evidence Potentially favorable evidence](/themes/custom/youthgov_custom/images/icon-findings-potentionally-favorable.png)
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.
The program was evaluated in a cluster randomized controlled trial involving 1,989 adolescents ages 13 to 17 recruited from 48 community-based organization summer programs (clubs) in Hampton Roads, Virginia. Each club was randomly assigned to one of three research conditions: a treatment group receiving the Possessing Your Power intervention, a treatment group receiving the Choosing the Best intervention, or a control group receiving a program on career exploration and college preparation. The study collected data with surveys administered before the start of the intervention (baseline), and again 6 and 12 months after the end of the intervention.In this study, researchers examined program impacts on a measure described as "risky sexual behavior". That measure is a binary variable that takes the value of 1 if the adolescent had unprotected sex, meaning the adolescent did not use a condom or birth control every time for recent sexual activity (in the past three months), and takes the value of 0 if the adolescent used a condom or birth control every time for recent sexual activity or if the adolescent avoided sexual activity in the previous three months.Six months after the program ended, researchers found that adolescents participating in the intervention who were sexually inexperienced at baseline were less likely to report that they did not use a condom or birth control every time for sexual activity in the past three months than their counterparts in the control group (odds ratio = 0.31, confidence interval = 0.19 to 0.52). The study found no evidence of statistically significant program impacts on that outcome
