The purpose of this study was to develop and validate the Concerns about Counseling Racial Minority Clients (CCRMC) scale among counselor trainees. Sample 1 was used for an exploratory factor analysis and confirmatory factor analysis. Four factors were identified, Managing Cultural Differences ([alpha] = 0.82), Offending or Hurting Clients ([alpha] = 0.87), Biased Thoughts and Behaviors ([alpha] = 0.81), and Client Perceptions ([alpha] = 0.77). The coefficient alpha for the CCRMC was 0.90. The results support the validity of the scale. The scores on the CCRMC and its subscales have positive associations with fear of negative evaluation from others (r = 0.19 to 0.40) and negative associations with general counseling self-efficacy (r = -0.30 to -0.46) and multicultural intervention self-efficacy (r = -0.30 to -0.64). The CCRMC significantly predicted fear of negative evaluation, session management self-efficacy, and multicultural intervention self-efficacy over and above multicultural social desirability. The validity evidence was not different between White and minority graduate trainees. In Sample 2, the estimated 1-week test-retest reliabilities ranged from 0.75 to 0.96 for the CCRMC and its four subscales. (Contains 5 tables.)
