This is an economic evaluation of an augmented reality-based intervention for preventing risky sexual behavior and teen pregnancy in Latina youth. The program, Mighty Girls, is designed to empower middle school Latinas with the skills they need to resist peer pressure that would otherwise accelerate their involvement in sexual behavior, allowing them to delay their initiation of intercourse and ultimately reduce their risk for teen pregnancy and sexually transmitted infections. Mighty Girls uses cutting-edge technology to create a novel, highly interactive video game that provides a live, realistic simulation of peer pressure. Players talk directly with avatars as they would with peers in their everyday life. This intervention focuses on building communication skills for resistance that are derived from evidence-based programs that do not jeopardize friendships and incorporate Latino cultural values (Marianismo, Personalismo, Simpatía) – skills valued by middle school Latinas. This trial is evaluating the costs, potential health benefits, and cost savings to the healthcare system.
