Measurement invariance of the Multigroup Ethnic Identity Measure (MEIM) across Bulgarian, Dutch and Greek samples

The Multigroup Ethnic Identity Measure (MEIM; Phinney, 1992) is a widely used instrument to quantify the way people think, feel, and behave regarding their ethnic origin. This instrument is commonly used to compare groups of people from different ethnic and/or cultural backgrounds. However, in order for these comparisons to be accurate, measurement invariance between groups needs to be tested and this is what has been done in the current study. First, confirmatory factor analyses were conducted separately for data sets with Bulgarian, Dutch, and Greek adolescents. Second, configural and scalar invariance were tested. Finally, comparisons between Bulgarian, Dutch, and Greek adolescents were made on their scores on MEIM.
