Study Findings
This study evaluated the program with a randomized controlled trial involving high-risk mothers and fathers recruited from community-based locations in Los Angeles County, California. Couples were randomly assigned to either a treatment group that was offered the program or to a control group that received a 90-minute didactic HIV prevention curriculum. Surveys were administered immediately before the intervention (baseline), immediately after the intervention, and at follow-ups conducted three, six, and 12 months after the program ended.
In one set of longitudinal analyses, the study found that across the baseline, three-month follow-up, and six-month follow-up, the proportion of males and females who reported having had sex without a condom in the past three months declined by a statistically significantly greater amount for the treatment group than for the control group. In a separate set of analyses that incorporated the 12-month follow-up, the study found that while there were favorable treatment effects observed through the 6-month period, there was an unfavorable effect of the intervention by the 12 month period, where there was a statistically significantly higher rate of unprotected sex among the treatment group.
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.
