Thesis advisor: Paul Poteat / Sexual minorities (e.g., lesbian, gay, and bisexual individuals) are at higher risk for mental and physical health disparities than heterosexuals, and research has related some of these disparities to minority stressors such as institutional heterosexism, sexual prejudice, and discrimination. Yet, there is a dearth of research elucidating factors that predict the development of these health risks, and factors that protect and promote resiliency against them. Building on the minority stress model, the present study utilized relational cultural theory to situate sexual minority health disparities within a relational framework. Specifically, the study examined the mediating and moderating factors between the deleterious effects of distal stressors (i.e., heterosexist relational disconnections such as discrimination and victimization) and proximal stressors (i.e., self-disparaging relational images such as internalized homophobia, sexual orientation concealment) on mental and physical health for sexual minorities. Among 719 sexual minority adults, structural equation modeling analyses were used to test three models of: the relations between minority stressors and health; mediating effects of diminished agency, loneliness, and shame on the relations between minority stressors and health; and the moderated-mediation effects of growth-fostering relationships with peers, mentors, and community on the mediating pathways between minority stressors and health. Results indicated that heterosexist distal and proximal minority stressors predicted poor mental health (i.e., depression, anxiety, and suicidality) and physical health (i.e., cardiovascular disease risk, distressing physical symptoms). The relations between proximal minority stressors and health were mediated by diminished sense of agency, loneliness, and shame, and there were mixed results for the relations between distal stressors and health. Although the direct effects of growth-fostering relationships were significant in predicting lower levels of diminished agency, loneliness, and shame, these factors had mixed moderating effects. Findings have research, practice, and policy implications that underscore the possible mechanisms by which sexual minority stressors lead to poor health. Researchers and practitioners need to addresses and advocate against societal forces contributing to heterosexist relational disconnections and for sexual minority health policies and research. / Thesis (PhD) — Boston College, 2014. / Submitted to: Boston College.
