Predicting Recidivism by Mentally Disordered Offenders Using the LSI-R:SV

The Level of Service Inventory—Revised: Screening Version (LSI-R:SV) has proven to validly predict reoffending in general offender populations but has not previously been studied specifically with offenders who have a major mental illness, including those with a dual diagnosis. This research project measures the validity of the LSI-R:SV for use with 208 mentally ill offenders who were released from a secure forensic hospital in Melbourne, Australia. Results indicate that the LSI-R:SV is a good predictor of recidivism among mentally disordered offenders. However, the LSI-R:SV does not reliably predict recidivism in individuals who attracted a dual diagnosis. Further research needs to reevaluate risk factors associated with recidivism in offenders with a dual diagnosis.
