Transdisciplinary collaboration and endorsement of pharmacological and psychosocial evidence-based practices by medical and psychosocial substance abuse treatment providers in the United States

Aims: To examine the relative contribution of providers' professional affiliation (medical vs. non-medical), involvement in research, and training needs for associations with endorsement of the following evidence-based practices (EBPs): (1) pharmacological-buprenorphine treatment and (2) psychosocial-Cognitive Behavioural Therapy (CBT). Methods: Secondary analysis from a 2008 survey of a national sample (n = 571) of substance abuse treatment providers (medical, social workers, psychologists and counsellors) affiliated with the United States National Institute on Drug Abuse's National Drug Abuse Treatment Clinical Trials Network. Multivariate linear regression models to analyze cross-sectional survey data. Findings: Results demonstrated that medical providers and providers with previous research involvement more strongly endorsed the effectiveness of buprenorphine over CBT. Compared to medical providers, psychosocial providers more strongly endorsed CBT. There was a positive association between needing training in rapport with patients and endorsement of buprenorphine and a negative association with CBT. There was a positive association between needing training in behavioural management and needs assessment and endorsement of CBT. Conclusions: Results underscore the importance of providers' involvement in research and the need for training medical and non-medical providers in practice areas that can purposely enhance their use of pharmacological and psychosocial EBPs.
