Objectives: (1) Compare service utilization among LGB+ and straight-identified students. (2) Assess rates of mental health concerns among LGB+ students only. Participants: Undergraduates (N = 675) reported on their sexual orientation, mental health conditions, and past service providers. Methods: Logistic regression was used for aim 1 and descriptive statistics for aim 2. Results: LGB+ students were more likely than straight-identified students to seek services for anxiety (odds ratio [OR] = 2.051; p < 0.01) or depression (OR = 3.058; p < 0.001) and from a counselor/therapist/psychologist (OR = 2.937; p < 0.001) or their university's counseling/health services (OR = 1.933; p < 0.01). Bisexual students utilized the most services. Conclusions: Colleges must ensure that programing, outreach, and overall support for the mental health needs of their LGB+ students are being met so that this vulnerable population continues to seek services.
