This study examined the convergent validity of 2 youth psychopathy instruments, the Psychopathy Checklist: Youth Version (PCL: YV) and the Youth Psychopathic Trait Inventory (YPI) and their relationship with problem behaviors and recidivism in an Australian sample of young offenders in custody. The PCL: YV demonstrated a capacity to identify severely antisocial youth; however, the tool was unable to differentiate between potentially psychopathic and nonpsychopathic antisocial youth. The YPI was receptive to a wide variety of problem behaviors which precluded the unique identification of core psychopathic traits in the sample. Both instruments were unable to meaningfully distinguish between recidivists and nonrecidivists. As such, the PCL: YV and the YPI demonstrate limited utility for antisocial young offenders in custody. Further research on the durability and developmental manifestation of psychopathy in adolescents is necessary before these instruments are employed in similar contexts. Implications for the clinical use of psychopathy measures are discussed.
