Victimization and family rejection of sexual orientation are two particularly salient stressors facing lesbian, gay, and bisexual (LGB) young people. While initial research has established a link between these sexuality-related stressors and LGB youth mental health outcomes, the factors that underlie this relationship remain unclear. The current study examined the role of negative LGB identity in mediating the relationship between sexuality related stress (i.e., victimization, family rejection) and youth outcomes (i.e., internalizing problems, public outness, substance use, and cigarette smoking). Participants included 81 LGB young people (ages 14 to 25) recruited through college groups, youth organizations, study advertisements, and friend referrals. Path analyses revealed that victimization and family rejection experiences were related to youth internalizing problems via negative LGB identity. Similar results were found for a model predicting public outness. However, stressors and health risk behaviors were not related through negative LGB identity, although some direct relationships between stressors, substance use, and smoking emerged. Limitations and implications of the present study are discussed.
