A Drug Court Outcome Evaluation Comparing Arrests in a Two Year Follow-up Period

Since the first drug court in Miami in 1989, the drug court movement has spread throughout the United States, influencing how drug-involved offenders are treated in the criminal justice system. This paper reports on an outcome evaluation of a drug court in San Mateo County, California. Arrest rates were compared for drug court participants (N=618) and non-participants (N=75), and for graduates (N=257) and non-graduates (N=361). Factors associated with rearrest were assessed for participants in both groups. During a two-year follow-up period, there were no significant differences in rearrest rates between the participant and non-participant groups. Comparisons between graduates and non-graduates showed lower rearrest rates for graduates (19% vs. 53%, χ(2)(1)=73.5, p<0.01). In a model including participants and non-participants, only a prior history of conviction predicted an increased likelihood of rearrest whereas being female and older decreased the likelihood of rearrest. In addition, among drug court participants only, graduating decreased the likelihood of rearrest.
