There has been a recent push to extend the construct of psychopathy into adolescence, primarily as a result of the impressive reliability, validity, and utility of this construct in samples of adults. The value of this work rests, however, on creating an equally reliable and valid assessment tool for adolescents. One promising measure is the Psychopathy Checklist: Youth Version (A. E. Forth, D. S. Kosson, & R. D. Hare, 2003). The current study uses a large, diverse sample of serious adolescent offenders to assess the overall fit of various underlying factor structures of this measure and to test the equivalence of these models across sex and race/ethnicity. The results suggest that either a 3-or 4-factor model provides the best overall fit and that these models are invariant across sex and race/ ethnicity. The decision to use the 3-or 4-factor model will likely hinge on researchers' underlying conceptualization of psychopathy, specifically whether antisocial behavior is viewed as a core feature of this construct.

This interest has been fueled by findings that measures of psychopathy are unsurpassed predictors of recidivism (Hart, Kropp, & Hare, 1988) and that psychopaths are among the most versatile, prolific, and violent offenders (Rice, Harris, & Quinsey, 1990). Unfortunately, there is also the belief that this condition is exceptionally difficult to treat effectively (Ogloff, Wong, & Greenwood, 1990;Rice, Harris, & Cormier, 1992; cf. Skeem, Monahan, & Mulvey, 2002, for another perspective). Taken together, these findings have made psychopathy research a highly topical and controversial area.

First, the study of psychopathy during childhood or adolescence may reveal important insights into the etiology of this disorder (Forth & Burke, 1998;Lynam, 1996). Second, given the recalcitrant nature of psychopathy in adulthood, some have suggested that intervention and treatment efforts might yield more success if implemented at an earlier age (Forth & Mailloux, 2000;Frick, Barry, & Bodin, 2000). Third, the assessment of psychopathy during adolescence might be useful for risk assessment and case management of juvenile offenders (Campbell, Porter, & Santor, 2004;Corrado, Vincent, Hart, & Cohen, 2004). Thus, there are a number of important reasons to explore the construct of psychopathy among adolescents.Despite these rationales for studying adolescent psychopathy, several authors have expressed serious concerns regarding the applicability of this construct in children and adolescents (Edens, Skeem, Cruise, & Cauffman, 2001;Seagrave & Grisso, 2002). Hart, Watt, and Vincent (2002) posed three broad questions: (a) Does juvenile psychopathy exist, (b) does it resemble adult psychopathy, and (c) can it be assessed reliably? These concerns revolve aroun...
