In contemporary research and clinical practice, Robert Hare's Psychopathy Checklist-Revised (PCL-R) is the psycho-diagnostic tool most commonly used to assess Psychopathy. Because an individual's scores may have important consequences for his or her future, the potential for harm, if the test is used or administered incorrectly, is considerable, so that the test should only be considered valid if administered by a suitably qualified and experienced clinician under controlled conditions.

Psychopathy Checklist-Revised (PCL-R)

This is a clinical rating scale with 20 items. Each of the items in the PCL-R is scored on a three-point (0, 1, 2) scale according to specific criteria through file information and a semi-structured interview. A value of 0 is assigned if the item does not apply, 1 if it applies somewhat, and 2 if it fully applies. Overview.
