Previous research has found that lesbian, gay, bisexual, transgender, questioning, queer, and other sexual and gender minority (LGBTQ+) individuals report greater suicide ideation than non-LGBTQ+ individuals. According to the interpersonal theory of suicide, desire for suicide (i.e., active suicide ideation) occurs when thwarted belonging (lack of reciprocal caring relationships) and perceived burden (self-hatred and feeling like a liability on others) are experienced simultaneously, and the individual feels hopeless that these states will change. Both the minority stress model and the gender minority stress and resilience model examine distal, or external stressors (e.g., discrimination, rejection, violence, victimization, and nonaffirmation) and proximal or internal, stressors (e.g., concern about future victimization and discrimination, mistrust, internalized homophobia and transphobia, and concealment) among sexual and gender minority individuals, which create stressful environments and mental health problems, including suicide ideation. Applying minority stress theories to the interpersonal theory of suicide would suggest minority stressors among all LGBTQ+ individuals may contribute to thwarted interpersonal needs and suicide ideation. The relation between the outness of an LGBTQ+ individual and suicide ideation may be influenced by thwarted interpersonal needs and minority stress.
Participants in the current study will include individuals who identify as LGBTQ+ who will complete assessments of suicide ideation, thwarted interpersonal needs, minority stress, and LGBTQ+ outness. We will test a moderated mediation model where the association between low levels of outness and high suicide ideation is mediated by thwarted interpersonal needs (burdensomeness/low belongingness), and the relationship between outness and thwarted interpersonal needs is moderated by minority stress.
