Substance abuse treatment and criminal justice involvement for SSI recipients: results from Washington state.

This study examined the association between receiving substance abuse treatment and subsequent criminal justice involvement. The sample consisted of Supplemental Security Income (SSI) recipients in the state of Washington that were determined to be in need of treatment. Fifty-two percent of those clients entered substance abuse treatment during the study period, while 48% did not. Arrests, felony convictions and convictions for less serious crimes were tracked for 8343 adults for one year following the end of an index treatment episode. Results showed that entering treatment was associated with reduced risks for each outcome. In addition, further analyses were conducted just on those entering treatment. Among that subset of the study population, the completion of treatment and having an episode of treatment lasting at least 90 days were both associated with reduced criminal justice risks. These results suggest that efforts to provide substance abuse treatment for SSI recipients have the potential to provide substantial public benefits.
