Objective: Develop and test feasibility of a mobile videogame intervention to decrease high-risk sexual behavior in black and Hispanic adolescents. Materials and Methods: Iterative design to develop intervention in partnership with target audience. Feasibility and preliminary impact data collected at baseline, following 2-3 hours of gameplay and at 8-week follow-up. Results: Twenty-six 15-17-year-olds completed pilot testing: 16 (62%) were male, 20 (77%) black or Hispanic. Pilot testing demonstrated feasibility, including producing a usable videogame prototype, incorporating videogame testing within a high school, and participants' acceptability of the videogame. Participants' gameplay experience reflected that most would play the videogame again (77%), stated that they felt responsible for the choices they made in the videogame (73%), and would tell their friends to play the videogame (58%). Most suggested adding more videogame content to further engage participants. From baseline to follow-up, participants demonstrated improvements in condom and contraception self-efficacy (P = 0.003), risk perceptions (P = 0.009), and high-risk sexual behavior knowledge (P < 0.0001). Among black or Hispanic adolescents, we found improvements in summary measures of intentions (P = 0.04), self-efficacy (P = 0.003), risk perceptions (P = 0.002), and sexual knowledge (P = 0.0002). Adolescents with previous sexual experience showed similar improvements. Conclusion: Pilot testing of an innovative videogame, developed in partnership with the target audience, demonstrated feasibility and preliminary impact with this cohort of black or Hispanic adolescents. We developed a usable videogame prototype and gained important data about how to enhance the next videogame iteration. Future plans include targeting an older age group to maximize our ability to measure potential impact among sexually experienced adolescents.
