Considering the grand challenge of migration and the increasing attention on this topic in international management, exploring the experience of multicultural individuals is highly relevant in today’s world and particularly in international organizations. We therefore used a global sample to develop a scale to measure this construct. We follow standard procedures in developing our scale. First, we used Vora and colleagues’ (2019) conceptual definition of individual-level multiculturalism, which was based on a review of the literature across five disciplines, as a basis for our scale. Second, we generated items by reviewing existing scales, adapting and developing items to tap into this construct. After we generated an initial set of items, we asked for feedback from experts and multicultural individuals, revising the scale as needed. Third, we engaged in content validation, revising the scale after results from the first content validation, and then conducting a second content validation test. Fourth, we conducted an exploratory factor analysis (EFA). Results suggest that items generally load upon the three dimensions of knowledge, identification, and internalization by culture. Fifth, we conducted confirmatory factor analyses (CFAs). Finally, we tested for convergent, discriminant, and predictive validity.
