Examining the unique and additive effect of trauma and racial microaggressions on substance use risk among Black young adults

Abstract

Objective: Exposure to traumatic events is linked to adverse health outcomes, including substance use. Contemporary models have conceptualized racism, including racial microaggressions, as a form of trauma. However, few studies have been conducted examining the unique and additive effect of racial microaggressions within models that include exposure to traditional forms of trauma on substance use outcomes, as well as whether effects vary by gender. Method: Three hundred and ninety-nine Black young adults between 18 and 29 (61% female, mean age 20.7) completed measures on problem alcohol and cannabis use, and experiences of trauma and racial microaggressions. Results: Controlling for age, gender, income, race (i.e., monoracial vs. multiracial), and recruitment source, regression analyses showed that racial microaggressions predicted problem substance use above the effect of trauma exposure. Moreover, exoticization/assumptions of similarity and workplace/school microaggressions primarily accounted for the effect of racial microaggressions on substance use risk. One gender effect was found, with trauma exposure associated with lower cannabis use for Black males and a nonsignificant effect found for Black females. Conclusions: Racial microaggressions provide unique and additive understanding in risk for substance use outcomes among Black young adults above effects observed from exposure to traditional forms of trauma. This finding highlights the significance of racial microaggression on health outcomes for Black young adults and can inform future research in the area of trauma exposure and substance use risk among this population of young people.
