This survey study investigated the direct and indirect relationships among intergroup contact, in-group size, out-group homogeneity, in-group homogeneity, and prejudice. The participants were 299 White women from seven Catholic congregations in the United States. The survey results indicated that in-group size was positively related to prejudice toward racial out-group members. Intergroup contact also mediated the relationship between in-group size and prejudice. Moreover, perceptions of out-group homogeneity not only correlated positively with prejudice, but also mediated the relationship between quantity and quality of intergroup contact and prejudice. Finally, perceptions of in-group homogeneity were positively associated with prejudice. These results not only demonstrate the value of the frequency and depth of intergroup contact on reducing prejudice, but also highlight the role of in-group size in infl uencing opportunities for contact. Moreover, perceptions of heterogeneity/uniqueness of both in-group and out-group members appear to serve as mechanisms through which contact reduces prejudice.
