Adolescents (ages 13-19) are disproportionately affected by HIV, accounting for 21% of all new infections in the U.S. in 2019. Although CDC and USPTF recommend HIV screening among adolescents, testing rates are very low (\<10% have ever been tested). Furthermore, in the U.S., 44% of 13-24-year-olds who are HIV-positive are unaware of their status - the highest percentage of undiagnosed infections of all age groups.
As such there is a need for interventions that aim to increase HIV testing in adolescents. This study builds upon the work of a previous text-based sexual health intervention program called G2G. The G2G pilot randomized controlled trial showed adolescents in the active treatment arm were \>3x more likely to report being tested for HIV at follow-up compared to those in the control arm. Given the success of HIV testing behaviors in G2G this current study will aim to update G2G with the latest HIV prevention and testing science, tailor the intervention content so it is modern and inclusive of all adolescents, and test its effectiveness on the outcome of validated HIV testing (e.g., photo of HIV test result). We will test this in a nationwide randomized controlled trial with 360 adolescents aged 13-19.
The primary efficacy outcome measure is HIV/STI testing via self report and objective evidence (e.g., photo of their test results) at 3 month and 6 month follow up surveys. Our study hypothesizes that participants assigned to the treatment arm of the intervention will have higher odds of having received an HIV test at 3 and 6 month follow up compared to those in the control arm. Ultimately, increased HIV testing in this group will mitigate transmission rates and improve the HIV prevention and care continua in this population.
