Protocol Version
Version 5.0
This study evaluated the program using a cluster randomized controlled trial that involved 5,633 students in 9th grade in 44 Chicago Public Schools. Schools were randomly assigned either to a group that implemented TOP or to a control group that did not implemented TOP but implemented their standard teen pregnancy and/or STI prevention curricula. The study collected outcome data immediately after the end of the program (about 10 months after the baseline).

The study examined program effects on having sex and having sex without using a condom in the last three months. Immediately after the end of the program, the study found no evidence of statistically significant program impacts on those outcomes.

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.
