The role of racial/ethnic identity in the association between racial discrimination and psychiatric disorders: A buffer or exacerbator?

The present study tests whether and how racial/ethnic identity moderates the psychological burden associated with racial discrimination. The theoretical concept of identity-relevant stressors suggests that racial discrimination will be associated with stronger psychological burden for people who put more values on their racial/ethnic backgrounds (i. e., racial/ethnic identity as an exacerbator). Conversely, racial/ethnic identity may be a protective resource to buffer any negative mental health consequences of racial discrimination (i. e., racial/ ethnic identity as a buffer). We adjudicate these two competing hypotheses, while also examining whether the moderating effect of racial/ethnic identity varies by race/ethnicity or nativity. The data are from the 2013 National Epidemiologic Survey on Alcohol and Related Conditions-III. Our findings reveal a race/ethnicity-dependent pattern: High racial/ethnic identity functions as an exacerbator for Whites, American Indians/Alaska Natives, and Latinxs, but moderate racial/ethnic identity functions as a buffer for Asians and Blacks in handling racial discrimination. In addition, the moderating effect of racial/ethnic identity is more pronounced among the U. S.-born than the foreign-born. The present study contributes to the knowledge base by showing that racial/ ethnic identity does not universally protect-nor does it universally exacerbate-the psychiatric burden of racial discrimination. Rather, whether it mitigates or intensifies the mental burden of racial discrimination depends on its level and race/ethnicity.
