This investigation reports on the development and initial validation of the anti-racism behavioral inventory, a measure designed to assess anti-racism awareness and behavior among students in counseling and counseling psychology programs within the United States (US). Data from 513 participants were collected over three related studies. Factor analyses suggested that the 21-item scale was best represented as a bifactor model with one general anti-racism behavior factor and three domain-specific factors, namely individual advocacy, awareness of racism, and institutional advocacy. Additional validity was supported through inverse associations with measures of symbolic racism and color-blind racial attitudes, as well as positive associations with scores on the Quick Discrimination Index. Potential utility of the measure and future directions for ongoing development is discussed.
