This study is a randomized controlled trial to test acceptability, feasibility and preliminary efficacy of an interactive computer-based intervention (ICBI) with individualized feedback to promote sexual health in adolescents and young adults. The intervention uses physician avatars and uses elements of motivational interviewing to elicit sexual risk behaviors and motivation to change risky behavior. Feedback includes instructive video modules. Participants were asked to identify one behavior to change and were reassessed at 3-month follow-up for interim sexual behavior including condom and birth control use. Participants were tested for chlamydia, gonorrhea, and pregnancy(females) at baseline and 3-month follow-up.
