The Hare Psychopathy Checklist-Revised (PCL-R) is the international “gold standard” for the diagnosis of psychopathy in adults. Measuring interpersonal and affective features as well as impulsive and antisocial behaviors, the PCL-R has been found to be a reliable and valid diagnostic instrument in hundreds of peer-reviewed studies conducted in community, mental health, and correctional.

  1. The Psychopathy Checklist (PCL; Hare, 1980) and its revision (PCL-R; Hare, 1985a, in press) are clinical rating scales that provide researchers and clinicians with reliable and valid assessments of psychopathy.

Dr. Hare has spent over 35 years researching psychopathy and is the developer of the Hare Psychopathy Checklist-Revised (PCL-R), and a co-author of its derivatives, the Psychopathy Checklist: Screening Version (PCL:SV), the P-Scan, the Psychopathy Checklist: Youth Version (PCL:YV), and the Antisocial Process Screening Device (APSD). He is also a co-author of the Guidelines for a Psychopathy Treatment Program. The Hare Psychopathy Checklist-Revised, with demonstrated reliability and validity, is rapidly being adopted worldwide as the standard instrument for researchers and clinicians. The PCL-R and PCL:SV are strong predictors of recidivism, violence and response to therapeutic intervention. They play an important role in most recent risk-for-violence instruments. The PCL-R was reviewed in Buros Mental Measurements Yearbook (1995), as being the 'state of the art' both clinically and in research use. In 2005, the Buros Mental Measurements Yearbook review listed the PCL-R as 'a reliable and effective instrument for the measurement of psychopathy and is considered the 'gold standard' for measurement of psychopathy.

“If I wasn’t studying psychopaths in prison, I’d do it at the stock exchange”, says Dr. Hare

Dr. Robert Hare is a Canadian psychiatrist who’s a world-renowned expert on psychopaths. His Hare Psychopathy Checklist-Revised (PCL-R)“is a diagnostic tool used to rate a person’s psychopathic or antisocial tendencies. People who are psychopathic prey ruthlessly on others using charm, deceit, violence or other methods that allow them to get with they want. The symptoms of psychopathy include: lack of a conscience or sense of guilt, lack of empathy, egocentricity, pathological lying, repeated violations of social norms, disregard for the law, shallow emotions, and a history of victimizing others”.

The twenty traits assessed by the PCL-R score are:
