title: Convergent and Predictive Validity of the Jesness Inventory in a Sample of Juvenile Offenders.
abstract: The present study examined the convergent and predictive validity of the Jesness Inventories (JI) in a sample of 138 juvenile offenders, completed in the course of routine service delivery. JI profiles were compared with ratings on three standardized forensic clinical scales: the Youth Level of Service/Case Management Inventory, Psychopathy Checklist: Youth Version, and Violence Risk Scale-Youth Version. The JI Asocial Index and the Undersocialized Active and Group-Oriented Conformist Interpersonal Maturity Level (I-level) subtypes demonstrated the strongest pattern of convergence and most consistently predicted recidivism. The Asocial Index did not incrementally predict recidivism after controlling for scores on the standardized forensic clinical scales; however, meaningful differences among broad I-Level groups (I-3 and I-4) remained after controlling for risk. Risk-need-responsivity applications of the JI (i.e., in terms of treatment dosage, identifying treatment targets, and adaptation of services) are discussed within the context of a comprehensive forensic assessment framework to inform case formulation, service delivery, and decision making with justice involved youth.
