The authors present the development and examination of the "Client Assessment of Multicultural Competent Behavior" (CAMCB) scores. The CAMCB was designed to measure therapists' multicultural competent behaviors within the context of therapeutic process, from clients' perspective. In this article, three-phases of the study are presented detailing (a) the development and administration of the CAMCB to a sample of clients (Phase 1), (b) exploration of the initial factor structure of CAMCB items (Phase 2, exploratory factor analysis [EFA]; N = 281), and (c) the cross-validation of the CAMCB exploratory factor structure and examination of convergent validity (Phase 3, confirmatory factor analysis [CFA]; N = 282). The EFA results identified a 23-item three-factor CAMCB exploratory model, accounting for 53.78% of the variance. The CFA results validated a three-factor oblique 19-item CAMCB model, accounting for 59.88% of the variance, and evidence of convergent validity was supported by a positive and yet small to moderate correlation between the CAMCB and Cross-Cultural Counseling Inventory-Revised-7 scale scores (r = 0.246, p < 0.001).
