Introduction
The Original Hare Psychopathy Checklist is a psychological assessment tool designed to assess the presence of psychopathy in individuals. It consists of a 22-item checklist of perceived personality traits and observable behaviors. It is intended to be completed on the basis of a semi-structured interview along with a review of ancillary information.
The PCL was originally developed in the 1970s by Canadian psychologist Robert Hare for use in psychology experiments. It has since undergone revision to the newer PCL-R (Psychopathy Checklist - Revised) in which 2 of the questions from the original assessment were removed after statistical analysis showed said questions to be unhelpful.
Instructions
Please mark present, unclear, or absent regarding each of the following personality traits or observed behaviors.
