Spanish is the second most spoken language in the United States. Not all substance use disorder (SUD) treatment facilities provide treatment in Spanish. This study examined factors associated with SUD treatment facilities having counselors that provide treatment in Spanish. State-level estimates of Spanish-speaking individuals were derived from the American Community Survey 2019. SUD treatment facility characteristics were captured from the National Survey of Substance Abuse Treatment Services 2020. We examined a sample of 15,246 facilities which included 12,798 outpatient, 3554 nonhospital residential, and 1106 with both outpatient and residential programs. Binary logistic regression models were used to observe state-level proportions of Spanish speakers and facility-level characteristics as factors associated with a facility having counselors that provide treatment in Spanish. Approximately 23.3% of facilities had counselors able to provide treatment in Spanish. Among outpatient or nonhospital residential SUD facilities, those in a state with a larger proportion of Spanish-speaking individuals, facilities with pay assistance, facilities that accept Medicaid, and facilities that engage in community outreach had higher odds of having counselors that provide treatment in Spanish. Considering that less than a quarter of facilities provide treatment in Spanish, increasing the availability of linguistically appropriate and culturally responsive services for SUD is imperative. This national study is the first of its kind to examine associations between estimates of Spanish speakers and treatment facility characteristics associated with counselors that provide treatment in Spanish in outpatient and nonhospital residential SUD treatment.
