An Inmate Classification System Based on PCL

Abstract

Psychopaths represent a significant management challenge in a prison population. A sample of ninety-five male inmates from three medium security prisons was tested using the Hare Psychopathy Checklist: Screening Version (PCL:SV). Using traditional criteria, 22% of the inmates were classified as psychopaths. Scores on the two factor dimensions of the PCL:SV were used to develop a four-way classification system. Inmates in each quadrant present unique characteristics, both in terms of personality traits and behavior. Management and treatment options are outlined for each of the four quadrants.

Key Words:

• Psychopathy
• PCL:SV factor scores
• antisocial personality disorder
• prison inmates
