Objective: While understanding racial/ethnic disparities in mental health services use is a growing priority in colleges and universities, little is known the attitudes that may contribute to these disparities. Methods: This study investigates the relationship between clinic diversity, ethnic-racial identity, discrimination, and treatment attitudes. College students n = 250 (Asian 21%, Black 11%, Latinx 23%, and White 45%) participated in an online experimental task rating hypothetical clinic websites that varied by clinician diversity and completed a series of self-report questionnaires. Results: Clinician diversity did not influence treatment attitudes, but discrimination and ethnic-racial identity were significantly related to treatment attitudes. Additionally, the relationship between public regard and treatment attitudes was moderated by race/ethnicity. Conclusions: By focusing on treatment attitudes rather than behaviors, this study addresses potential areas of intervention to address racial/ethnic disparities in college mental health.
