There are two major program components: the DWI jail alternatives facility (under the sheriff's jurisdiction) and the intensive probation supervision component (operated by the probation department). Alcohol treatment services are essential elements of each component. The evaluation, which was conducted between August 1987 and January 1988, consisted of structured interviews with appropriate persons, questionnaires completed by project staff, and a statistical analysis of the program's impact. The evaluation yielded positive findings: a 1.7-percent felony DWI recidivism rate and a 5.8-percent DWI recidivism rate after approximately 1 year. The 11.7-percent combined DWI and non-DWI rearrest rate is also encouraging. Program participants are apparently true jail-bound offenders, and the reduced split-sentence dispositions are effective alternatives to jail. 17 references. For the full report, see NCJ-112121.
