Summary

The study investigates the impact of participating in the Intensive Drug and Alcohol Treatment Program (IDAPT) on misconduct in prison.  IDAPT is a residential program within Corrective Services NSW for prisoners with a drug or alcohol problem.

The study found that people who participated in IDAPT reduced their in-prison infractions by 73% in the years following participation, even after controlling for a wide range of offender and offence characteristics. No similar reduction was observed amongst a cohort of offenders who were referred to IDATP but did not commence the program due to a prison bed shortage.   

Further research is required to assess the impact of IDAPT on post-release recidivism.
