LGBT* youth are over-represented among homeless youth and they face unique circumstances from their non-LGBT* homeless peers, such as increased risks of psychological distress (Fredriksen-Goldsen et al. 2014). Through multi-group, structural equation modeling, I compare the effects of time homeless on mental health outcomes (e.g., psychological distress) as measured by the Kessler 6 (K6) scale mediated by social support across non-LGBT*, LGB, and trans* groups. Findings indicate that social support is a significant mediator between the time a youth is homeless and their mental health outcomes, regardless of LGBT* status. Youth who are homeless six months or longer have worse mental health and fewer social supports than youth who are homeless less than six months. Additionally, the more social support a youth has, the higher their mental health is; however, individuals assigned female at birth have fewer social supports than males.
