The study examines the underexplored topic of bicultural identity, specifically focusing on Bicultural Identity Integration (BII), which measures the degree to which a bicultural individual perceives their two cultural identities as compatible versus oppositional. The researchers identified personality (Big Five) and acculturation (acculturation stress, acculturation attitudes, bicultural competence) predictors of BII. Using a sample of Chinese American biculturals, they found that BII does not form a uniform phenomenon but encompasses two separate constructs: perceptions of distance (vs. overlap) and perceptions of conflict (vs. harmony) between cultural identities. Cultural conflict and cultural distance have distinct personality, acculturation, and sociodemographic antecedents. The study also developed new instruments to measure BII and its components, and used structural equation modeling to explore the relationships between these variables. Key findings include that cultural distance is predicted by low openness, low bicultural competence, a separation acculturation strategy, and linguistic and cultural isolation stressors, while cultural conflict is predicted by a neurotic disposition, linguistic acculturation stress, and intercultural relations stress. The study highlights the complex interplay of personality traits, acculturation experiences, and sociodemographic factors in shaping bicultural identity integration.The study examines the underexplored topic of bicultural identity, specifically focusing on Bicultural Identity Integration (BII), which measures the degree to which a bicultural individual perceives their two cultural identities as compatible versus oppositional.
