SERVICE RESEARCH OUTCOME STUDY (SROS)
The Services Research Outcome Study (SROS) is a follow-up 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 episodes, and will analyze treatment results in light of the type and cost of treatment services the clients received.
