HIV/STI, substance use, and mental health issues disproportionately affect racial/ethnic sexual minority young adults. These health vulnerabilities intensify across the life course, most notably when young adults are independent college students. To identify the perspectives of racial/ethnic sexual gender minorities living on or near an urban university, we implemented an intersectionality-informed SWOT (strengths, weakness, opportunities, and threats) analysis, as a qualitative community assessment situated within in a campus-community setting. The community needs assessment was the first step in the strategic prevention framework (SPF) to co-locate substance abuse, mental health, viral hepatitis, and HIV prevention care services for Latinx and Black/African American sexual gender minority young adults at a minority-serving institution. The SWOT analysis identified principles for selecting, adapting, and implementing an evidence-based intervention. The significance of these principles demonstrates the value of intersectionality in evidence-based interventions to influence health education and behavior among racial/ethnic sexual gender minorities.
