The Effect of Social Network Size and Composition on the Link Between Discrimination and Health Among Sexual Minorities

Objectives: Previous research has examined the link between discrimination and health in lesbian, gay, bisexual, and/or transgender (LGBT) individuals. The purpose of this study was to examine if health-promoting variables, like social networks, might disrupt this association. Method: Participants were 2,560 LGBT older adults who reported on the composition of their social network, level of discrimination, stress, and health/well-being. Results: Moderated mediation results indicated that social network size disrupted the associations between discrimination, stress, and health outcomes when social networks were (a) larger and (b) comprised of LGBT individuals (but not straight individuals), regardless of age. Discussion: Larger social networks that include fellow LGBT individuals helped buffer experiences of stress and discrimination on health outcomes among LGBT older adults. Implications for how protective factors can reduce the negative effects of discrimination and stress are discussed.
