Follow-up of former clients of a large multimodality drug treatment program

A follow-up study was conducted of a sample of 360 former clients of the Narcotics Treatment Administration program in Washington, D.C. Ninety-five percent of the persons sampled were located, and interviews were successfully completed with 81 percent of the total sample. Interviews were conducted 1 to 3 years following treatment. Findings indicate that a general decrease in drug use has occurred between the period immediately preceding treatment and time of the interview. Improvements were also realized in arrests and in employment and other prosocial activities.
