Online Racial/Ethnic Discrimination, Suicidal Ideation, and Alcohol Misuse Among Ethnoracially Minoritized College Students: The Roles of Internalized Racism and Ethnic Identity

Over the past decade, mental health problems have disproportionately increased among U.S. ethnoracially minoritized college students, though explanations for this disparity remain understudied. In the present study, we examined the direct and indirect associations between online racial/ethnic discrimination, suicidal ideation (SI), and alcohol misuse. We also investigated whether internalized racism helps explain the association between online racial/ethnic discrimination (i.e., individual or vicarious exposures) and SI and alcohol misuse. Lastly, we examined the moderating role of ethnic identity dimensions (i.e., exploration and commitment) in this indirect association. Participants included 494 ethnoracially minoritized college students ages 18-30 years (M = 19.62, SD = 2.08; 79% female; 60% Latine; 83% U.S.-born) from the U.S. who completed an online survey. Findings revealed that online racial/ethnic discrimination (i.e., individual and vicarious exposures) was directly associated with increased SI and alcohol misuse. The indirect association of online racial/ethnic discrimination (i.e., individual and vicarious) on SI via internalized racism was statistically significant. These indirect associations, however, were not observed with alcohol misuse. Ethnic identity commitment moderated the indirect association of vicarious, though not individual, online racial/ethnic discrimination on SI via internalized racism. These findings underscore the impact of online racial/ethnic discrimination on ethnoracially minoritized college students' mental health, identify internalized racism as a potential pathway through which this type of discrimination may confer risk for SI, as well as ethnic identity commitment as a potential protective factor that may buffer these harmful effects.
