Gay and bisexual youth make up 80% of all new HIV infections among adolescents ages 14-19 in the United States, yet interventions to improve sexual health outcomes in these youth are extremely limited. Our team has developed an intervention -- Parents and Adolescents Talking about Healthy Sexuality (PATHS) -- to reduce HIV risk for gay and bisexual youth by working with their parents to improve the ways parents communicate with their sons about sexual health. The intervention is all completed by parents online and takes 45-60 minutes to complete. The goal of this study is to test whether PATHS helps improve sexual health among gay and bisexual male teens ages 14-19. To do this 350 parent-adolescent dyads will be recruited online (50% of those dyads will be racial/ethnic minority). Parents will be randomized to receive either PATHS or a control (a film designed to general support parents of gay/bisexual youth). Parents and sons will then complete surveys every 3 months over a 1-year period. Families assigned to PATHS will be compared to families assigned to the film 6 months after the intervention. Then the families originally given the control film will receive PATHS, and all dyads will be followed for another 6 months. This allows us to test the effects of PATHS in the control arm (by comparing families' experiences in the 6 months before they received the PATHS to their experiences over the next 6 months). It also allows us to test whether families who originally received PATHS will continue to benefit 9 and 12-months after the intervention. To assess sexual health, adolescents will complete self-report measures of their comfort using condoms, their access to condoms, their knowledge of the correct way to use a condom, their intentions to use condoms, their awareness of pre-exposure prophylaxis as an HIV prevention method, and their attitudes toward PrEP. If they are sexually active, they will also report about their history of condom use during sex. Adolescents will also complete a video-recorded condom demonstration in which they will demonstrate the appropriate technique for applying a condom, using a real condom and a oval-shaped shampoo bottle. Finally, adolescents will self-report whether they have received an HIV test in the previous year, consistent with recommendations for gay and bisexual men by the Centers for Disease Control and Prevention.
