Substance use and addiction is a national healthcare concern affecting millions of families and individuals (National Institute on Drug Abuse [NIDA], 2018; Substance Abuse and Mental Health Services Administration [SAMHSA], 2018). To meet the needs of a growing client base, the addiction profession continues to expand (National Association for Alcoholism and Drug Abuse Counselors [NAADAC], 2018b). Additionally, the increase in ethnic minority or marginalized populations in the United States (United States Census Bureau, 2018) warrants a closer look at the preparedness of addiction counselors to serve a diverse client population. Previous literature has found marginalized or ethnic minority clients are more likely to drop out or not complete treatment compared to Caucasian clients (Cooper et al., 2010; Gonzalez et al., 2011; Guerrero et al., 2013). Despite these concerns, only one found study has examined multicultural counseling competency in addiction counselors (Lassiter & Chang, 2006). A non-experimental, correlational survey design was used to explore relationships between counselor recovery status, training, and counselor demographic variables on multicultural counseling self-efficacy in addiction counselors (N=283) using the Multicultural Counseling Self-Efficacy – Racial Diversity Form (MCSE-RD; Sheu & Lent, 2007). A MIMIC model analysis indicated significant differences based on race, multicultural education, and CACREP program attendance on multicultural counseling self-efficacy. Implications from this study and recommendations for future research are discussed.
