Biracial identity, psychological outcomes, and the role of identity autonomy.

OBJECTIVE: Racial identity invalidation occurs when others deny an individual's racial group membership. This stressor can detrimentally impact psychological well-being and may contribute to the development of race-based traumatic stress. While singular instances of invalidation can be distressing, prolonged exposure to racial identity invalidation may evoke a sustained stress response. This study examines how identity autonomy mediates the relationship between racial identity invalidation and psychological well-being among minority-White biracial individuals, shedding light on the risk and protective factors associated with race-based traumatic stress. METHOD: = 237) were biracial individuals who completed an online questionnaire that included the Identity Autonomy Scale, Racial Identity Invalidation Scale, Depression and Anxiety Scale subscale of Depression Anxiety Stress Scale-21, and Self-Esteem Scale. CONCLUSION: Identity autonomy plays a critical role as a mechanism through which racial identity invalidation contributes to specific types of psychological risks.
