The Multigroup Ethnic Identity Measure (MEIM) is a psychological tool designed to assess an individual's ethnic identity across multiple groups. Developed by researchers including Jean S. Phinney, the measure evaluates how individuals perceive their belonging to various ethnic groups and the significance of these identities in their lives. The MEIM consists of a series of statements that respondents rate based on their agreement. This helps to gauge aspects such as ethnic exploration and commitment, providing insights into how ethnic identity influences personal and social experiences. The measure is widely used in research related to cultural psychology and multiculturalism.
