Criminal Recidivism in Inmates with Mental Illness and Substance Use Disorders

Area of Science:

• Criminology
• Psychiatry
• Public Health

Background:

• Criminal recidivism is a significant concern with substantial clinical and policy implications.
• Understanding the interplay between mental illness, substance use disorders, and rearrest rates is critical for effective interventions.

Purpose of the Study:

• To investigate the association between mental illness, substance use disorders (SUDs), and criminal recidivism.
• To determine if specific psychiatric factors influence rearrest rates among formerly incarcerated individuals.

Main Methods:

• A review of 36-month postrelease data for nearly 10,000 New Jersey state inmates released in 2013.
• Analysis of rearrest rates based on diagnoses of mental illness, SUDs, both, or neither.
• Examination of the correlation between psychiatric decompensation risk factors and recidivism.

Main Results:

• Inmates with a substance use disorder (SUD) alone had the highest rearrest rate, followed by those with both SUD and mental illness.
• Individuals with neither diagnosis had lower rearrest rates than those with SUDs.
• No significant differences in recidivism were found based on specific mental disorder diagnoses or antipsychotic medication use.

Conclusions:

• Correctional institutions should prioritize addressing substance use disorders in incarcerated individuals.
• Targeted interventions for SUDs are essential for reducing criminal recidivism among returning citizens.
• Mental illness alone did not significantly predict higher recidivism rates in this cohort.
