This study examined the theoretical and measurement issues involved in the current study of Asian American ethnic identity development and acculturation. Specifically, an attempt was made to investigate the influence of acculturation in predicting prejudicial social attitudes. A total of 289 college students from 2 universities were given the Asian and Anglo Acculturation Scale, the Suinn-Lew Asian Self-Identity Acculturation Scale, and the Quick Discrimination Index. Results suggest that students who were more acculturated and who were Asian identified tended to have less prejudicial attitudes. Results also suggested that Asian American women tended to have less prejudicial attitudes than did Asian American men. Implications for counseling are discussed.
