D. Kosson, Ph.D.
R. D. Hare, Ph.D.

Technical Information

The normative data for the Hare PCL:YV consists of 2,438 youth located in Canada, United Kingdom, and United States. Nineteen different adolescent samples were collected and included offenders that were institutionalized, on probation, in open custody, referred for outpatient evaluation, and youth in the community.

Reliability and Validity
The Hare PCL:YV has proven through numerous studies to be strong in scientific validity. The studies include the evaluation of the concurrent validity of the Hare PCL:YV with respect to other measures of psychopathy and with respect to Conduct Disorder (CD). Also included is the review of convergent and discriminant validity of the Hare PCL:YV by examining the relationship between Hare PCL:YV Total scores and a variety of constructs that have proven to be related to psychopathy or independent of psychopathy in adult samples. Predictive validity of the Hare PCL:YV was also evaluated, in regard to the domains of recidivism and treatment outcome.
