ADOLESCENT PSYCHOPATHY Factor Structure and Correspondence With the Millon Adolescent Clinical Inventory

This study compared five proposed factor models of psychopathy in a sample of 227 adolescent incarcerated offenders and psy-chiatric inpatients. Results of confirmatory factor analysis indicated that both Cooke and Michie’s three-factor model and a four-factor parceled solution using Hare’s four factors provided excellent fit. The original two-factor model and the three- and four-factor models from the Psychopathy Checklist:Youth Version manual provided inadequate fit. Correlational analyses revealed a meaningful pattern of statistically significant relationships between psychopathy factor scores and several factor scores on the Millon Adolescent Clinical Inventory (MACI). Regression analyses indicated that Hare’s antisocial factor (Factor 4) provided incremental validity beyond other psychopathy factors in predicting scores on the MACI antisocial-delinquent factor
