Abstract
Follow-up outcomes in the 1st yr after treatment were studied in relation to time spent in treatment in the Drug Abuse Reporting Program. Follow-up interviews were completed with more than 3000 people admitted to drug abuse treatment during 1969-1972, including clients treated with methadone maintenance, therapeutic communities, outpatient drug-free programs and outpatient detoxification, and a group who completed intake procedures but did not return for treatment. Longer time in treatment was related to better posttreatment outcome, but clients who spent less than 3 mo. in treatment were not significantly different from the detoxification-only group or the intake-only group.
