Study Findings
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.
This study evaluated the program using a randomized controlled trial involving sexually active adolescent females recruited from four school- and community-based clinics in Minneapolis and St. Paul, Minnesota. Participants were randomly assigned to either a treatment group that received the 18-month Prime Time intervention or a control group that received usual clinic services. The study collected data with surveys administered before random assignment (baseline) and at 6, 12, 18, 24, and 30 months after the baseline survey. The study found that 30 months after the start of the program, students in the treatment group were statistically significantly more likely to report having been abstinent in the past six months. The study found no statistically significant impacts on the number of sexual partners in the last six months. The study also examined program impacts on measures of condom use and contraceptive use. Findings for these outcomes were not considered for the review because they did not meet the review evidence standards. Specifically, findings were reported only for subgroups of youth defined by sexual activity at follow-up. In addition, the study examined program impacts on measures of relational aggression and physical violence perpetration and victimization. Findings for these outcomes were not considered for the review because the outcomes fell outside the scope of the review.
