Abstract:
Information technology provides new avenues to increase opportunities to deliver HIV/STI prevention interventions in a confidential, sensitive, and engaging manner for youth. While technology-based HIV/STI interventions show promise in preventing HIV/STI among different populations, few have targeted young Latinas. This pilot study examined the feasibility and acceptability of a bilingual, web-based HIV/STI prevention intervention among Latino females aged 15-19. We used a mix-method approach, including a prospective 2-group design with 3 repeated measures, and a post-intervention focus group discussion. We recruited 14 participants from an alternative high school and randomized into each study condition. Participants took 5 structurally equivalent modules focusing on either HIV/STI prevention (intervention) or nutrition/exercise (comparison) and completed assessments before the intervention, immediately post-intervention, and 2 months post-intervention. The findings suggested that the intervention had high levels of feasibility and acceptability. We discuss the keys to success, challenges encountered, and future directions.
