Understanding what students bring to the classroom: moderators of the effects of diversity courses on student attitudes.

We investigated the impact of required diversity courses on students' understanding of racial inequality and their social development with regard to racial outgroups, with a specific focus on the effects of student race and empathy as moderators of diversity course effectiveness. First-semester students (N = 173), enrolled in either diversity courses or introduction to psychology, completed surveys at the beginning and end of the semester. Diversity courses increased understanding of White privilege, acknowledgment of blatant racism, and intersectional consciousness overall, but had a greater impact on intersectional consciousness for White students compared with students of color. White students taking diversity courses experienced a reduction in Protestant work ethic ideology that was absent for White students in psychology courses and for all students of color. Notably, empathy moderated the effect of diversity courses on both outgroup comfort and willingness to act to promote diversity.
