Ethnic and racial identity are among the most researched topics in the multicultural counseling literature. The popularity of these constructs, combined with ongoing controversies surrounding their measurement, warrants a critical examination by scholars in the field. The author contends that a combination of science and ideology has influenced the field and warns that a rigid and uncritical adherence to old paradigms will stifle growth and the production of useful knowledge. The author provides a review of measurement issues pertaining to ethnic and racial identity research and recommendations for future research and better practices involving ethnic and racial identity instruments.
