Research shows that, overall, substance misuse can lead to a variety of negative health outcomes, yet treatment is often underutilized by racial and ethnic groups, particularly by minoritized racial and ethnic populations. Screening, Brief Intervention, and Referral to Treatment (SBIRT) has been shown to be effective in changing substance use patterns across diverse settings and for diverse demographic groups. However, only a few studies have focused on treatment match and mismatch and whether individuals receive the appropriate level of care based on screening criteria. The purpose of this study was to investigate treatment match/mismatch and factors (e.g., service site, gender, race, ethnicity, age, SES) that predicted the likelihood of being mismatched to treatment. Of N = 3,412 individuals available for analyses, results showed that n = 2,222 were matched to treatment and n = 1,190 were mismatched to treatment. Logistic regression indicated service site, ethnicity, and age were significant predictors of treatment match/mismatch. There were no significant interactions between predictors and treatment match/mismatch. Exploratory results suggested that across predictors, individuals were more likely to receive a lesser intervention than what their screening score suggested. Agencies should attend to factors associated with mismatch to treatment. Future research should address why these factors may be associated with treatment mismatch and methods to reduce mismatch.
