Cross-ethnic equivalence of the Hopkins Symptom Checklist-21 in European American, African American, and Latino college students.

To determine if the Hopkins Symptom Checklist-21 demonstrates equivalent validity across different ethnic groups, the authors tested the factor structure of the instrument with a sample of European American (n = 514), African American (n = 154), and Latino (n = 229) college students using confirmatory factor analysis with tests of invariance across groups. For the most part, a 3-factor model with Performance, General, and Somatic factors fit equally well for all 3 racial/ethnic groups. Differences involved only a few items in terms of either the strength of a factor loading or an error term. The results generally support the validity of the use of the instrument for measurement of distress in these different racial/ethnic groups.
