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.

Details

The program was evaluated using a randomized controlled trial involving young men and women recruited from nontraditional education settings in several rural regions in Virginia. The settings included juvenile detention centers, alternative schools, night school programs, Community Services Board Programs, and programs of third-party service providers. Youth were randomly assigned to either a treatment group that received the Vision of You program or a control group that had the option of taking part in a healthy eating program called Eat, Move, Win. Surveys were administered immediately before the program (baseline), immediately after program completion (five to six weeks after baseline for the control group), three months after the program ended (about four months post-baseline for the control group), and nine months after the program ended (or about 10 months post-baseline for the control group). Study authors report findings only for the follow-up that took place nine months after the program ended.



The study found that nine months after the program ended, youth participating in the program were significantly less likely to report having had vaginal intercourse without using a condom or birth control in the past three months (effect size = -0.41). Nine months after the program ended, youth participating in the program also reported having significantly fewer sexual partners in the past three months than youth in the control group did (effect size = -0.19). The study did not find statistically significant differences between the groups in the likelihood of having had any vaginal intercourse in the past three months.



The study also examined program impacts on a measure of future orientation. This outcome fell outside the scope of the review.
