Simpson, D. D. & Brown, B. (Eds.) (December, 1999). Special issue on treatment process and outcome studies from DATOS. Drug and Alcohol Dependence.

Editors' Summary: This year's last issue of the journal Drug and Alcohol Dependence (December 1999) features a collection of new studies from the Drug Abuse Outcome Treatment Studies (DATOS) project, a collaborative research effort funded by the National Institute on Drug Abuse (NIDA) from 96 treatment programs in 11 U.S. cities. IBR at TCU, NDRI (National Development and Research Institutes), and the Drug Abuse Research Center at UCLA joined with NIDA in this 5-year project, which continued in the spirit of earlier national multi-site studies such as DARP (Drug Abuse Reporting Program) and TOPS (Treatment Outcome Prospective Study). The issue also reports on recent findings from a national treatment outcome study in England.]
