Ongoing disparities in alcohol use and negative mental health outcomes among sexual and gender minority (SGM) emerging adult victims of sexual violence call for improved, affirming intervention techniques tailored to the lived experiences of SGM individuals. This study addresses this gap through tailoring a pre-existing training to support survivors of sexual violence through peer-to-peer interactions. The preexisting intervention is called Survivors Supporting Self. This study has three aims to tailor the training program for SGM individuals and and supportive friends and/or family, to determine feasibility and acceptability of delivering the SSS+ program, and to assess the efficacy of the program for increasing intentions to improve social reactions to disclosures of sexual violence. Participants who identify as SGM and/or have LGBTQ+ identifying friends or family will be invited to participate. Additionally, this proposal will support training for undergraduate students. Our team will be complemented with 4 undergraduate research assistants annually who will provide lived experience expertise in addition to receiving mentored research experience that will lead to research careers in health professions. Completion of this study will result in an SGM-specific tailored intervention to improve social reactions provided upon disclosure of sexual violence among SGM emerging adults, which may lead to reductions in problematic drinking and other deleterious outcomes for this vulnerable group.
