Annotation

The Drug Abuse Treatment Outcome Study (DATOS) collected 1- year follow-up outcomes for 2,966 clients in outpatient methadone (OMT), long-term residential (LTR), outpatient drug-free (ODF), and short-term inpatient (STI) programs in 1991-93.

Abstract

LTR, STI, and ODF clients reported 50 percent less weekly or daily cocaine use in the follow-up year than in the preadmission year. Reductions were greater (p greater than .01) for clients treated for 3 months or more. Clients still in OMT reported less weekly or daily heroin use than clients who left OMT. Multivariate analysis confirmed that 6 months or more in ODF and LTR and enrollment in OMT were associated with the reductions. Reductions of 50 percent in illegal activity and 10 percent increases in full-time employment for LTR clients were related (p greater than .01) to treatment stays of 6 months or longer. The results replicated findings from 1979-1981 for heroin use in OMT and illegal activity and employment for LTR but not for illegal activity in OMT and ODF. 5 tables and 35 references
