The present study tested the moderating roles of ethnic identity and American identity on the association between perceived racial/ethnic discrimination and antisocial behaviors among Asian American college students. Using data from the Multi-Site University Study of Identity and Culture (MUSIC) collaborative, the sample included 1,362 East Asian and South Asian American college students. Perceived discrimination was significantly associated with antisocial behaviors for both East Asians and South Asians. Ethnic identity was not a significant moderator of the discrimination–antisocial behavior link, but American identity exacerbated the association between perceived discrimination and antisocial behaviors for both East Asians and South Asians. Interestingly, the explanatory power of the regression model was greater for South Asians than for East Asians in predicting antisocial behaviors. The importance of attending to American identity as a potential source of risk for Asian American college students exposed to racial/ethnic discrimination is discussed.
