Further analysis found that 52 percent of probationers who were referred to treatment were re-arrested
either during or after probation compared to 56 percent of those who were not referred
to treatment. The percentage of probationers who were re-arrested during probation was lower
for those who successfully completed treatment (22 percent) than those who did not successfully
complete treatment (55 percent). Similarly, the percentage of probationers arrested after
probation was significantly lower for those with successful treatment completion (27 percent)
compared to those with an unsuccessful completion (54 percent).
Compared to probationers in the sample who were not referred to treatment, probationers who
received only substance abuse treatment had significantly lower odds of being arrested either
during or after probationer. However, probationers who received a combination of treatment
types had a higher likelihood of recidivating during or after probation than those who were not
referred to treatment.
Of probationers whose discharge status was known, 56 percent successfully completed
probation. The southern region had a higher proportion of probationers successfully completing
probation, and the northern region had a significantly higher proportion of unsuccessful case
outcomes compared to the southern region. Analysis revealed that in the sample, being female,
being employed at least part-time, having a high-school diploma or GED, having a higher
income and being married significantly increased the odds of a probationer successfully
completing probation, findings that were similar to other studies (Morgan, 1994; Sims & Jones,
1997; Chanhatasilpa, MacKenzie, & Hickman, 2000; and Lurigio, Olson, & Snowden, 2009).
