The present study examines the underresearched topic of bicultural identity; specifically, we: (1) unpack the construct of Bicultural Identity Integration (BII), or the degree to which a bicultural individual perceives his/her two cultural identities as "compatible" versus "oppositional," and (2) identify the personality (Big Five) and acculturation (acculturation stress, acculturation attitudes, bicultural competence) predictors of BII. Differences in BII, acculturation stress, and bicultural competence were measured with new instruments developed for the purposes of the study. Using a sample of Chinese American biculturals, we found that variations in BII do not define a uniform phenomenon, as commonly implied in the literature, but instead encompass two separate independent constructs: perceptions of distance (vs. overlap) and perceptions of conflict (vs. harmony) between one's two cultural identities or orientations. Results also indicated that cultural conflict and cultural distance have distinct personality, acculturation, and sociodemographic antecedents.
