The purpose of the Youth Level of Service Case Management Inventory (YLS/CMI) is to assess, classify, and assist agencies with developing treatment and service plans according to the offender's criminogenic risk factors. Given the limited research in the predictive validity for this instrument, the current study attempts to examine this issue on a sample of 4,482 juveniles from Ohio who were given sentences in the community or to juvenile institutions. Results demonstrated the validity of the YLS/CMI in predicting recidivism for both settings. (Contains 5 tables and 2 notes.)
