Measurement invariance is crucial in counseling research and assessment because it ensures that scores have the same meanings across treatment conditions, time points, or diverse populations. We conducted a review and content analysis of articles that reported invariance testing and were published in selected counseling journals between 2010 and 2019 (N = 1165). Findings suggest a small proportion of published invariance tests (2.8%) had been undertaken by counseling researchers. We found that the majority of the articles that reported invariance testing in counseling research addressed gender and race/ethnicity. Implications for future research, counselor educator training, and clinical practice are discussed.
