The main purpose of the present study is to examine the predictive validity of the Youth Level of Service/Case Management Inventory (YLS/CMI) to Japanese juvenile offender population. Three hundred and eighty-nine juveniles who were released from the five Juvenile Classification Homes (JCHs) were followed for more than one year on average. Results demonstrate that those who show higher score on the YLS/CMI are more likely to recidivate than those who are not. A total score of the YLS/CMI also significantly contributes to predict faster time to recidivate. Furthermore, the superiority of actuarial risk measures over clinical risk judgment is confirmed. The overall findings support the applicability of the YLS/CMI among Japanese juvenile offenders. Practical implications and limitations to the current study are also discussed.
