Details

The program was evaluated in a cluster randomized controlled trial involving seventh graders in a suburban middle school in the southeastern United States. Out of 20 seventh-grade health education classes offered during the academic year, 11 were randomly selected to receive the AIM intervention and 9 were randomly selected for a control group that followed the standard curriculum. Student surveys were administered one week before the start of the intervention (baseline) and approximately three and 12 months after the intervention ended.

The study found that approximately three months after the intervention ended, adolescents participating in the intervention were significantly less likely to report having had sexual intercourse. At the time of the second follow-up conducted 12 months after the intervention ended, males participating in the intervention were significantly less likely to report having had sexual intercourse. The study found no statistically significant program impacts on sexual intercourse for other study groups at the time of the 12-month survey.

The study also examined program impacts on participants' intentions to have sex. Findings for that outcome were not considered for the review because they fell outside the scope of the review.

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.
