Exploring the association between sexual minority identity and depression through the mediating effect of negative social media experiences: A national survey of U.S. young adults (Preprint)

BACKGROUND Lesbian, gay, and bisexual (LGB) persons are disproportionately affected by depression and have high social media use rates. Negative social media experiences may modify depressive symptoms among LGB persons. We sought to assess the potential influence of negative social media experiences on the association between LGB orientation and depression. OBJECTIVE The aim of this study was to assess the potential influence of negative social media experiences on the association between LGB orientation and depression. METHODS We performed a web-based survey of a national sample of US young adults aged 18-30 years. We assessed the respondents' LGB orientation, negative social media experiences, and depression using the 9-item Patient Health Questionnaire. We used generalized structural equation modeling to assess both the direct and indirect effects (via negative social media experiences) of LGB orientation on depression while controlling for relevant demographic and personal characteristics. RESULTS We found a conditional indirect effect (ab path) of LGB orientation on depressive symptoms via negative social media experience (a: observed coefficient 0.229; P<.001; bias-corrected bootstrapped 95% CI 0.162-0.319, and b: observed coefficient 2.158; P<.001; bias-corrected bootstrapped 95% CI 1.840-2.494). The results show that among LGB respondents, for those who reported negative social media experiences in the past year, a 1 unit increase in these experiences was associated with a 0.494 unit increase in depressive symptomatology. CONCLUSIONS Our results suggest that higher rates of depression among LGB young adults are partially explained by negative social media experiences; these results could help inform future patient/provider conversations about mental health risk and protective factors related to social media use. Reducing these experiences and increasing positive social media experiences among LGB persons may mitigate depressive symptomatology in this population.
