      Abstract
      Previous investigations of the Level of Service Inventory – Ontario Revision (LSI-OR) have examined individual subgroups of offenders (e.g., women, Aboriginal offenders), which has made comparisons of its predictive validity between specific offender groups suspect. This study was conducted on a complete cohort of 26,450 offenders who were released from Ontario provincial correctional facilities, sentenced to a conditional sentence, or who began a term of probation in 2004. Participants were followed up for at least four years to collect recidivism information on numerous subgroups of offenders including males (81.7%), females (18.3%), Aboriginal (6.4%), Black (7.3%) and Caucasian offenders (59.2%). Analyses revealed that the LSI-OR scores are positively correlated with recidivism (r = .441, p < .001), and similar correlations were found for all offenders regardless of gender or race, (Aboriginal r = .377, p < .001; Black, r = .420, p < .001; Caucasian, r = .417, p < .001; Male, r = .439, p < .001; Female, r = .426, p < .001). LSI-OR scores are also correlated with severity of the recidivism offence, (r = .098, p
