Lesbian, gay, and bisexual (LGB) emerging adults often seek support from their peers if they lack support from their family of origin. We predicted that peer social support would moderate the link between negative family relationships and psychosocial adjustment, such that in the context of family rejection, experiencing more peer support would predict lower levels of anxiety, depression, and internalized homonegativity (IH) and higher self-esteem. Sixty-two (27 females) LGB individuals (ages 17–27, M = 21.34 years, SD = 2.65) reported on their families’ attitudes toward homosexuality, experiences of family victimization, peer social support, anxiety and depression symptoms, IH, and self-esteem. Results showed that peer social support moderated the link between negative family attitudes and anxiety and also moderated the link between family victimization and depression. The moderating effects suggest that having a supportive peer group may protect against mental health problems for LGB emerging adults who lack support from their family of origin.
Lesbian, gay, and bisexual (LGB) individuals report higher levels of stressful interpersonal conflicts with others because of their divergence from heterosexual social norms. In a biopsychosocial model of minority stress, we tested diurnal cortisol slopes and internalized homonegativity (IH) as two potential mechanisms linking experiences of LGB-related stress to depression. The sample consisted of 27 lesbian and bisexual young women and 35 gay and bisexual young men (N ¼ 62; age, 17-27, M ¼ 21.34 years) from the greater metropolitan area of Montréal, Québec. We predicted that (a) LGB-related stress, IH, and diurnal cortisol slopes would be positively associated with each other and with depression; and (b) flatter diurnal cortisol slopes and/or greater IH would mediate the link between LGB-related stress and depression. LGB-related stress, diurnal cortisol slopes, and IH were positively associated with depression, and mediation analyses showed that diurnal cortisol slopes mediated the link between LGB-related stress and depression. These findings suggest that external stressors associated with being LGB can impact individuals' physiological coping resources, thus affecting their psychological health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
