The present thesis explores LGBT2Q+ (lesbian, gay, bisexual, transgender (trans), Two-Spirit, queer/questioning, plus) and racialized mental health service utilization within Canada using intersectionality-informed quantitative methodology, separated into additive and multiplicative stages. Data from the 2020 LGBT2Q+ Health Survey (N = 1542) were analyzed using modified Poisson regression. Additive analyses explored mental healthcare utilization as framed by the Andersen Behavioural Model of Healthcare Utilization categories: predisposing, enabling, and need. Results show that predisposing and need factors are more statistically associated with mental healthcare utilization, and that there are distinct intracategorical (within-group) differences in subgroups, particularly between racialized and Indigenous respondents. Bivariate associations between mental health conditions and predisposing factors further suggest increased mental health needs and mental health service utilization in sexual orientation and gender minorities. The multiplicative stage built upon results from the additive stage to further explore differences in mental health service utilization. Two-way to four-way interaction models of Andersen predisposing factors show persistent trends in identifying as non-White, trans or gender-diverse, more polysexual orientations, and being born outside of Canada as factors associated with increases in likelihood of mental health service utilization. In bivariate analyses, being racialized was associated with lower mental health service utilization as well as mood and anxiety disorders, yet being racialized was associated with an increase in mental health service use when the previously mentioned intersectional factors were considered. Findings demonstrate how plurality of systems of marginalized identities intersect to create distinct health outcomes.
