Any re-arrest during or after probation
Compared to probationers who were not referred to treatment, probationers who received only
substance abuse treatment had significantly lower odds of being arrested either during or after
probation (odds ratio=0.78, p<0.05).
Compared to probationers who were not referred to treatment, those who successfully completed
their treatment had a significantly lower likelihood of being rearrested (odds ratio=0.49,
p<0.001); while those who unsuccessfully completed treatment had higher likelihood of re-arrest
(odds ratio=1.90, p<0.001).
Probationers who received a combination of treatment types had higher likelihood of recidivating
during or after probation (odds ratio=1.46, p<0.05) than those who were not referred to
treatment.
Table K in the Appendix of this report provides the results of the logistic regression of re-arrest
during or after probation on treatment discharge status and treatment type.
Arrest during probation
Compared to probationers who were not referred to treatment, probationers who received only
substance abuse treatment had a significantly lower likelihood of being rearrested during
probation (odds ratio=0.71, p<0.001).
Compared to those who were not referred, those who successfully completed their treatment had
were significantly less likely to be re-arrested (odds ratio=0.39, p<0.001); while those who
unsuccessfully completed treatment had a higher likelihood of re-arrest (odds ratio=1.78,
p<0.001).
Table L in the Appendix of this report provides the results of the logistic regression of re-arrest
during probation on treatment discharge status and treatment type.
Re-arrest after probation
Compared to probationers who were not referred to treatment, probationers who received only
cognitive-behavioral therapy had a significantly lower likelihood of being re-arrested after
probation (odds ratio=0.43, p<0.05) as did “other” treatment types (odds ratio=0.44, p<0.05).
Cognitive-behavioral therapy is a form of psychotherapy that emphasizes the important role of
thinking in how the patient feels and what they do.
Compared to probationers who were not referred to treatment, those who successfully completed
their treatment had a significantly lower likelihood of being re-arrested (odds ratio=0.57,
p<0.001), while those who unsuccessfully completed treatment had a higher likelihood of re-arrest
(odds ratio=1.82, p<0.001). Table M in the Appendix of this report provides the results of
the logistic regression of re-arrest after probation on treatment discharge status and treatment
type.
