Outpatient Drug Abuse Treatment Studies (ODATS)

The National Drug Abuse Treatment System Survey (NDATSS) is a longitudinal program of research into organizational structures, operating characteristics, and treatment practices of outpatient drug treatment programs in the United States. This is done through interviews with program directors and clinical supervisors. In some publications, this research is referred to as the Outpatient Drug Abuse Treatment Studies (ODATS). Data in this collection include Wave V, Wave VI, Wave VII, Wave VIII, and Wave IX.

NDATSS includes four prior waves of data collection from substance abuse treatment programs surveyed in 1984, 1988, 1990, and 1995. Waves II through IV can be found at ICPSR here.

Wave I is not planned for public release because it had a significantly different sample design than the other waves.
