The Hare Psychopathy Checklist-Revised (PCL-R) is a diagnostic tool used to rate a person's psychopathic or antisocial tendencies. It was developed in the 1970’s by Dr. Robert Hare, a Canadian professor and researcher renowned in criminal psychology, who has spent three decades studying the concept known as the psychopath and based partly on Hare’s work with prison inmates in Vancouver.
Because psychopaths are often repeat offenders who commit sexual assaults or other violent crimes again and again, the PCL-R is used in the courtroom and in institutions as an indicator of the potential risk posed by individuals in psychiatric units or prisoners. The results of the examination have been used as a factor in deciding the length and type of prison sentences and the treatment subjects should or should not receive. It is accepted by many in the field as the best method for determining the presence and extent of psychopathy in a person. A modified youth version is also available for ages 12 – 18.
The Hare PCL-R contains two parts, a semi-structured interview and a review of the subject's file records and history. A 20-item symptom rating scale that allows qualified examiners to compare a subject's degree of psychopathy with that of a prototypical psychopath. Each of the twenty items is given a score of 0, 1, or 2 based on how well it applies to the subject being tested.
Because an individual's score can have important consequences for his or her future, Hare argues that the test should only be considered valid if administered by a suitably qualified and experienced clinician under scientifically controlled and licensed, standardized conditions.

A prototypical psychopath would receive a maximum score of 40, while someone with absolutely no psychopathic traits or tendencies would receive a score of zero.
A score of 30 or above qualifies a person for a diagnosis of psychopathy.
People with no criminal backgrounds normally score around 5.
Many non-psychopathic criminal offenders score around 22.
