Leeds Drug Intervention Programme/Integrated Offender Management Programme run by Developing Initiatives for Support in the Community (DISC Leeds DIP/IOM project)

This document describes an evaluation of the DISC Leeds DIP/IOM project, which aims to reduce re-offending among prolific offenders with substance misuse histories by providing support in areas such as drug treatment, housing, employment, and mental health. The evaluation used data from 340 offenders who participated in the project between 2009 and 2013, comparing them to a control group formed using information from the Offender Assessment System. The methodological approach involved creating matched treatment and control groups and analyzing re-offending rates, frequency, time to re-offence, and severity of re-offences. The results showed no statistically significant difference in one-year re-offending rates between the treatment and control groups, although there was a significant reduction in tier 2 severity offences for the treatment group. The evaluation concludes that there is insufficient evidence to determine the project's impact on re-offending rates, and it highlights the limitations of statistical matching in the analysis. The document is released under the Open Government Licence and includes a glossary of terms related to re-offending measures and statistics. **This summary was written by an AI model and therefore should not be considered a definitive summary of the report.
