Abstract

Purpose: Lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ+) people face mental health disparities. These disparities are amplified in the Southern regions of the United States. This study assessed the role of outness, discrimination, and other demographic variables on possible serious mental illness (SMI) among LGBTQ+ Southerners. Methods: This study used data from the 2017 LGBT Institute Southern Survey, a cross-sectional convenience sample of 6502 LGBTQ+ adults living in 14 Southern states. Multivariable logistic regression was performed to examine differences between those with and without possible SMI. Results: Outness was associated with a lower likelihood of possible SMI (odds ratio [OR]: 0.696, 95% confidence interval [CI]: 0.574-0.844, p = 0.001), especially when controlling for discrimination in the past 12 months (OR: 0.693, 95% CI: 0.576-0.834, p ≤ 0.001) and lifetime discrimination (OR: 0.678, 95% CI: 0.554-0.829, p = 0.001). Lifetime discrimination was associated with a higher likelihood of possible SMI (OR: 1.413, 95% CI: 1.034-1.932, p = 0.033), as was discrimination experienced in the past 12 months (OR: 1.626, 95% CI: 1.408-1.877, p ≤ 0.001). Black/African American respondents had the lowest percentage of possible SMI (21.0%) compared with other races, despite having lower or comparable rates of outness. Conclusion: These results indicate a possible promotive effect of outness against possible SMI among LGBTQ+ Southerners, as well as possible promotive group-level factors among Black/African American LGBTQ+ Southerners. Policies and interventions that address discrimination against LGBTQ+ Southerners should be expanded, and future research should address how the relationships between outness, discrimination, and mental health outcomes may vary by subgroup.
