The research describes the construction and validation of the Ethno-cultural Identity Conflict Scale (EICS) based on 3 independent samples totaling 975 immigrants, international students, and members of ethnic minority groups. The convergent validity of the 20-item scale was supported by its correlations with Self-Concept Clarity (r = –.65), Sense of Coherence (r = –.58), Identity Distress (r = .48), and the Cultural Conflict (r = .62) and Cultural Distance (r = .21) components of the Bicultural Identity Integration Scale. EICS was also linked to contemporary acculturation research with integrated migrants experiencing less conflict than those who were separated, assimilated, or marginalized.
