Racial identity is an aspect of self-concept that is important to the mental and behavioral health of Black individuals. Yet, much of the current research on racial identity is based on self-report measures which may impact findings due to reporting biases. One way to alleviate some of the measurement concerns is to use implicit measures to assess racial identity. The purpose of the present study was to examine whether an implicit assessment of racial identity, specifically racial centrality, provided a unique contribution to the understanding of risk for psychological distress and substance use among Black young adults above potential effects observed from an explicit measurement of racial identity. Additionally, the potential moderating effect of implicit racial identity, controlling for explicit racial identity, on the association between racial discrimination and these health outcomes was also examined. One hundred and forty-seven Black young adults participated in this study. Contrary to our hypothesis, there was no significant main effect of implicit racial centrality on depressive symptoms or substance use after accounting for explicit racial centrality. However, after controlling for explicit racial centrality, a significant moderating effect of implicit racial centrality on the relationship between racial discrimination and substance use was observed. Although support for all of our hypotheses was not definitively found, our findings can be added to this emerging area of study. Additionally, potential explanations for the findings are provided that can be used to inform future research in this area to better understand the utility of assessing for implicit racial identity among Black young adults.
