Internalized racism is a destructive, yet insidious psychological effect of racism. Although it has garnered increased attention in the research and clinical community due to its pervasive impact in racial minority individuals, empirical research on this topic has been limited. At the time of this study, no existing scale captures the key dimensions of internalized racism of Asian Americans. This study attempted to fill this gap by developing a self-report instrument that identified the key dimensions of this psychological construct. Seven hundred and fourteen Asian Americans participated in this study, and exploratory and confirmatory factor analyses were conducted to investigate the factor structure of the scale. Results indicated that the Internalized Racism Scale for Asian Americans (IRSAA) has five factors, which are Endorsement of Negative Stereotypes, Sense of Inferiority, Denial or Minimization of Racism, Emasculation of Asian American Men, and Within-group Discrimination. This dissertation also examines and discusses the evidence of convergent, discriminant, and incremental validity for the IRSAA subscales.
