Details

A more recent study conducted by a separate group of researchers evaluated the program with a younger sample of adolescents and using a quasi-experimental design. The study involved a sample of sixth and seventh grade students in Georgia. The study compared a sample of 119 students who volunteered to participate in the CAS-Carrera program with a comparison group of 85 students recruited from the afterschool programs of three local Boys and Girls Clubs. Surveys were administered immediately before the program (baseline) and then annually for three years.

The study found that a year after the program started, adolescents in the intervention group were statistically significantly less likely than those in the comparison group to report having ever had sexual intercourse. The study found no statistically significant program impacts on reported rates of having had sex without a condom or other birth control. For the follow-up surveys conducted two and three years after the program started, the study found no statistically significant program impacts on rates of sexual initiation or unprotected sex.

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.
