Development of the Cultural Humility Scale-Short Form (CHS-SF)

Objective: The purpose of the present study was to develop a brief version of the Cultural Humility Scale (CHS; Hook, J. N., Davis, D. E., Owen, J., Worthington, E. L., Jr., & Utsey, S. O. (2013). Cultural humility: Measuring openness to culturally diverse clients. Journal of Counseling Psychology, 60(3), 353-366. https://doi.org/10.1037/a0032595) to reduce participant burden in clinical settings.Method: In Study 1 (n = 247), we used confirmatory factor analyses (CFA) and two-factor item response theory (IRT) models to create the Cultural Humility Scale-Short Form (CHS-SF). In Study 2 (n = 272), we performed cross-validation of the CHS-SF. We also examined construct validity using the Cross-Cultural Counseling Inventory-Revised (CCCI-R; LaFromboise, T. D., Coleman, H. L. K., & Hernandez, A. (1991). Development and factor structure of the Cross-cultural Counseling Inventory-Revised. Professional Psychology: Research and Practice, 22(5), 380-388. https://doi.org/10.1037/0735-7028.22.5.380) and the Working Alliance Inventory (WAI; Tracey, T. J., & Kokotovic, A. M. (1989). Factor structure of the Working Alliance Inventory. Psychological Assessment: A Journal of Consulting and Clinical Psychology, 1(3), 207-210. https://doi.org/10.1037/1040-3590.1.3.207).Results: The CHS-SF has two 3-item subscales (positive/negative cultural humility). The CFA for the CHS-SF showed excellent model fit, and all coefficients demonstrated good-to-excellent reliability for the whole scale. The factor structure was replicated with a unique sample, and we also found evidence of measurement invariance by gender and race/ethnicity. The CHS-SF again showed adequate estimates of reliability. The CHS-SF was positively correlated with both the CCCI-R and WAI.Conclusion: The CHS-SF offers an efficient tool for measuring therapists' cultural humility based on client perceptions during treatment. Like the original CHS, it is well-suited for routine care and training environments. Implications for practice and research, limitations, and directions for future inquiry are discussed.
