Transgender and gender expansive emerging adults: The moderating role of thwarted belongingness on mental health.

Transgender and gender expansive emerging adults experience multiple forms of gender minority stress, which affect their mental health and wellbeing. Belongingness has been identified as a factor that fosters resilience among this population, with potential protective effects. Few studies have explored the role of thwarted belongingness and its potential moderating effect on the relation between gender minority stress and mental health. This study recruited a sample of 93 transgender and gender expansive emerging adults between the ages of 18 and 21 to examine whether thwarted belongingness significantly moderates the relations between gender minority stressors and mental health symptoms. We found evidence that thwarted belongingness moderates the relation between social rejection and depressive symptoms and the interaction effect between thwarted belongingness and victimization was significantly associated with psychological stress. For both of these associations, high levels of thwarted belongingness amplified the positive relation between gender minority stress and mental health symptoms. In contrast, at low levels of thwarted belongingness, the relation between rejection and depression was negative and the association between victimization and psychological stress was no longer statistically significant. Findings suggest that factors that minimize or interrupt thwarted belongingness among transgender and gender expansive emerging adults may be points of intervention to improve mental health outcomes in this population.
