Racial/ethnic discrimination as race-based trauma and suicide-related risk in racial/ethnic minority young adults: The explanatory roles of stress sensitivity and dissociation.

Objective: Drawing on race-based trauma models, the present study examined common reactions to trauma exposure (i.e., stress sensitivity, dissociative symptoms, depressive symptoms), as potential explanatory factors in the relation between racial/ethnic discrimination and suicide-related risk among racial and ethnic minority young adults. Method: A group of racial and ethnic minority ( N = 747; 61% women; 63% U.S.-born; 34% Asian American) young adults, ages 18-29 ( M = 19.84; SD = 2.22), completed a battery of self-report measures online. Accounting for demographics and other trauma exposures, direct and indirect associations between racial/ethnic discrimination and suicide attempt (SA) through stress sensitivity, dissociative symptoms, depressive symptoms, and suicide ideation (SI) were examined using hierarchical linear regression models and bootstrapping methods. Results: There was a direct association between racial/ethnic discrimination and stress sensitivity, dissociative symptoms, and depressive symptoms, but not SI or SA, after accounting for demographics and trauma exposures. There was also an indirect association between racial/ethnic discrimination and SI and SA through stress sensitivity, dissociative symptoms, and depressive symptoms. Conclusion: Experiences of racial/ethnic discrimination may function as a source of traumatic stress in racial and ethnic minority young adults to confer risk for SI and SA via stress sensitivity, dissociation, and depressive symptoms. Addressing racial/ethnic discrimination may help reduce suicide-related risk by targeting stress-related exposures particularly relevant to racial and ethnic minority young adults.
