The Services Research Outcome Study (SROS) is a follow-on to the 1990 Drug Services Research Survey (DSRS). The SROS provided for a five year post-discharge follow-up of a broadly representative sample of approximately 3,000 drug clients treated during 1989 to 1990. The study ascertained their behavior up to five years after the 1989-1990 treatment episode, and will analyze treatment results in light of the type and cost of treatment services the clients received.  Pre-treatment variables included demographic characteristics, prior treatment history, criminal justice history, social support, and addiction severity. Treatment variables included duration of treatment episodes, key services received, program staffing, ownership, resource base, and costs. Post-treatment variables include: employment; criminal justice status, such as probation or incarceration; and further treatment episodes.

The Services Research  Outcomes Study (SROS), the first nationally representative study of substance abuse outcomes, confirms that both drug abuse and criminal  behavior are reduced following drug abuse treatment:   inpatient, outpatient, and residential.
