National Drug Abuse Treatment (NDAT) Clinical Trials Network: Mid-Atlantic Node

Principal Investigator: Maxine L. Stitzer, Ph.D.

The National Drug Abuse Treatment Clinical Trials Network (CTN) was established by the National Institute on Drug Abuse (NIDA) in 1999 to improve substance abuse treatment nationwide. This is accomplished by conducting effectiveness research in community-based clinics and fostering adoption of evidence-based interventions and practices. 

The Mid-Atlantic Node of the CTN is based in the Johns Hopkins Department of Psychiatry and Behavioral Sciences on the Bayview Campus and has collaborative affiliations with Virginia Commonwealth University (VCU), Friends Research Institute (FRI), and several local drug abuse treatment providers. Participating JHU faculty include Dr. Maxine Stitzer, Node Principal Investigator, and Dr. George Bigelow. Other affiliated faculty include Drs. Dace Svikis (VCU), Ellinore McCance-Katz (VCU) and Robert Schwartz (FRI).

The Mid-Atlantic Node has been actively involved in several national research studies and served as lead on a large multi-site trial that demonstrated effectiveness of prize-based incentives for improving treatment outcome in both methadone maintenance and psychosocial counseling treatment programs. Primary study results can be found in the Archives of General Psychiatry (Petry et al., 2005; Peirce et al., 2006).
