title: Predicting dangerousness with two Millon Adolescent Clinical Inventory psychopathy scales: the importance of egocentric and callous traits.
abstract: Psychopathy in youth has received increased recognition as a critical clinical construct for the evaluation and management of adolescents who have come into contact with the law (e.g., Forth, Hare, & Hart, 1990; Frick, 1998; Lynam, 1996, 1998). Although considerable attention has been devoted to the adult construct of psychopathy and its relation to recidivism, psychopathy in adolescents has been less thoroughly researched. Recently, a psychopathy scale (Murrie and Cornell Psychopathy Scale; Murrie & Cornell, 2000) was developed from items of the Millon Adolescent Clinical Inventory (MACI; Millon, 1993). This scale was found to be highly related to the Psychopathy Checklist-Revised (Hare, 1991) and was judged to have demonstrated good criterion validity. A necessary step in the validation process of any psychopathy scale is establishing its predictive validity. With this in mind, we investigated the ability of the MACI Psychopathy Scale to predict recidivism with 55 adolescent offenders 2 years after they had been evaluated at a juvenile court evaluation unit. In addition, we devised a psychopathy scale from MACI items that aligned more closely with Cooke and Michie (2001) and Frick, Bodin, and Barry's (2001) recommendations for the refinement of psychopathy and tested its predictive validity. Results indicate that both scales had predictive utility. Interpersonal and affective components of the revised scale were particularly important in the prediction of both general and violent reoffending.
