Participant demographics (n = 499).

PurposeDisparities in the behavioral health outcomes for lesbian, gay, bisexual, transgender, and queer+ (LGBTQ+) adults—such as depression, anxiety, and alcohol use—are often attributed to experiences of discrimination, victimization, and lack of supportive environments, including hetero- and cis-normative family settings. Yet, how family environments in childhood influence LGBTQ+ adults’ behavioral health and internalized homonegativity has not been extensively examined.MethodsThis study utilized a U.S. national dataset of LGBTQ+ adults (N = 499). Data were collected in November 2020 using an online survey. A series of multivariate ordinary least squares regression models and Sobel tests were performed.ResultsResults showed that as homophobic messages from family increased, levels of depression (β = .19, p β = .17, p β = .13, p β = .11, p β = .15, p z = 3.35, p z = 3.09, p z = 2.80, p z = 2.66, p z = 3.76, p z = 3.45, p ConclusionStudy findings underscore the importance of inclusive climates within a family and internalized homonegativity as a mediator for LGBTQ+ individuals’ behavioral health. Implications for intervention and future research are discussed.
