Relationship quality, COVID stress, and mental health in sexual and gender minority young adults

Sexual and gender minority (SGM) individuals, particularly those assigned female at birth (AFAB), have shown poor mental health outcomes during the COVID-19 pandemic. This issue highlights the importance of identifying factors that may promote SGM-AFAB mental health during the pandemic and protect SGM-AFAB individuals against the negative psychological effects of COVID-related stress. Grounded in previous research and theory suggesting that high quality romantic relationships have promotive (i.e., main) and protective (i.e., stress-buffering) effects on partner’s mental health, we explored associations between relationship quality, COVID-related stress, and mental health among SGM-AFAB individuals. Specifically, we tested whether (1) higher relationship quality, as a promotive factor, was directly associated with fewer mental health problems (depressive and anxiety symptoms, problematic alcohol and cannabis use), and (2) relationship quality, as a protective factor, had a stress-buffering effect, reducing the negative effect of COVID stress on mental health within SGM-AFAB young people. Between May 2020-July 2021, 227 SGM-AFAB individuals (ages 19–35; M = 23.5) in current romantic relationships completed measures of pandemic-related stress, relationship quality, depressive and anxious symptoms, and problematic alcohol and cannabis use. As hypothesized, relationship quality was negatively associated with anxious and depressive symptoms and problematic cannabis use. Relationship quality attenuated the positive association between COVID stress and depression, but not the other mental health outcomes. Findings suggest that high-quality romantic relationships may promote mental health and have a stress-buffering effect for depressive symptoms among SGM-AFAB individuals during major society-wide stressors.
