Adolescent Pregnancy Prevention Among Youths Living in Group Care Homes: A Cluster Randomized Controlled Trial.

Objectives: To determine if the Power Through Choices (PTC) intervention can increase the use of birth control and reduce pregnancy among system-involved youths living in group care homes.

Methods: We performed a 2-arm cluster randomized controlled trial involving group care homes operated by child welfare or juvenile justice systems in California, Maryland, and Oklahoma with assessments immediately before and after the intervention, and at 6- and 12-month follow-up. We collected data from 2012 to 2014 via self-administered questionnaires. Participants (n = 1036) were young (mean age = 16.1 years), predominantly male (79%), racially/ethnically diverse (37% Hispanic, 20% Black, 21% White, 17% multiracial), and sexually experienced (88%).

Results: At 6-month follow-up, participants in the intervention group had significantly lower odds of having recent sexual intercourse without using birth control (adjusted odds ratio [AOR] = 0.72; 95% confidence interval [CI] = 0.52, 0.98). At 12-month follow-up assessment, participants in the intervention group had significantly lower odds of ever being pregnant or getting someone pregnant (AOR = 0.67; 95% CI = 0.46, 0.99).

Conclusions: The results suggest that PTC is an effective sexual health education intervention that can be implemented with system-involved youths who represent a sexually experienced multiracial youth population.
