Methods: We examined four waves of the National Drug Abuse Treatment System Survey (NDATSS), a nationally representative longitudinal dataset (2010- 2017), to assess the effect of OTPs’ structure, organization, and service delivery on wait time to treatment and retention in treatment. We conducted comparative and predictive analysis in an analytic sample of treatment programs (162 in 2000, 173 in 2005, 282 in 2014, and 300 in 2017). We considered the moderated effect of workforce diversity and treatment structure on wait time and retention.
Results: The main findings suggest significant differences in wait time and in retention. Average waiting days decreased in the last two waves of the NDATSS (2014-2017) (post Medicaid expansion per the Affordable Care Act), while retention rates varied across years. Key findings show that programs with both a higher percent of African American staff and a higher percent of African American clients were associated with longer wait times to enter treatment. Programs with both a higher percent of Latino staff and a higher percent of Latino clients were negatively associated with retention in treatment.
Discussion: Findings show decreases in wait time over the years with significant variation in retention during the same period. Higher workforce diversity was associated with higher wait time and lower retention when programs also had high percentages of African American and Latino clients. Findings have implications for the role of high diversity in OTPs, which may also represent OTPs with low resources and training potentially explainig lower access and engagement. This work contributes to the conceptual and empirical literatures on the role of diversity, as an main indicator of cultural competence, and the fault lines that determine when diversity may contribute to positive minority outcomes.
