Background/Aim: Over-representation of individuals with mental illness in the criminal justice system. In response, court diversion programs were established to reduce the number of mentally ill persons in the criminal justice system. In New South Wales (NSW), the Statewide Community and Court Liaison Service (SCCLS) provides court diversion assessments and assistance to individuals with a mental illness appearing at local court. This study assesses the effectiveness of mental health court diversion in reducing criminal offending and improving health outcomes for those for court diversion seen by the SCCLS.

Methods: This data linkage study examined a cohort of individuals (from 2007 onwards) assessed by the NSW SCCLS for court diversion and linked to offending data held by NSW Bureau of Crime Statistics and Research (BOSCAR) via the Centre for Health Record Linkage (CHeReL). The statistical analysis involved a comparison of the criminal reoffending outcomes of those recommended and granted court diversion compared to those not granted court diversion. This comparison will include the three different types of diversion, and analysis of socio-demographics and clinical variables that impact on diversion and reoffending rates.

Results and Conclusion: Mental health court diversion is shown to be effective at reducing criminal reoffending outcomes for individuals with mental illness. Reduction in re-offending seen for both men and women, for both hospital-based and community-based diversion, and for both risk of any and violent reoffending.
