title: Concurrent and predictive validity of the psychopathy checklist: youth version across gender and ethnicity.
abstract: The concurrent and predictive validity of the Psychopathy Checklist: Youth Version (PCL:YV) were examined across gender and ethnicity using multiple outcome measures on a community-based sample of 130 adjudicated youths. The PCL:YV demonstrated concurrent validity with externalizing behavior problems but, it is important to note, was also associated with internalizing measures of negative affect. With a mean follow-up period of 3 years, the PCL:YV was found to predict general and violent recidivism in male, Native Canadian, and Caucasian youths. However, the PCL:YV demonstrated weaker concurrent and predictive validity with girls and failed to predict nonviolent recidivism in all subgroups. Implications of the findings for clinical practice are discussed.
