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.

The researchers involved in this study understand the importance of a strong partnership between themselves and the treatment programs. This alliance can help the CTN build its own plan for promoting the use of proven, effective and innovative treatment methods.
