The "Baseline Study" is designed to help us better understand the   community treatment programs participating in the NIDA Clinical Trials Network (CTN).  Using a series of surveys, the study will be used to:

  • Describe the programs and practitioners delivering drug abuse treatment services within the CTN.
  • Build a system that can track changes in program and staff characteristics.
  • Allow treatment program managers to compare their program to others -- both within the CTN and nationwide.
  • Promote studies of organizational change and the characteristics that predict whether research-based treatment strategies will become part of usual treatment in a program.
CTN-0008 Study Protocol


The surveys describe 106 corporations (95% response rate) providing drug abuse treatment in 348 treatment units (91% response rate).  Most treatment units are not-for-profit and are not affiliated with health care or mental health care organizations and tend to be larger than the modal drug abuse treatment program.  In the CTN, hospital-based services are over-represented and programs based in mental health centers are under-represented.  The treatment units serve a heterogeneous patient population, and the inpatient, residential, methadone, and outpatient levels of care vary in the services provided.
