The Hare Psychopathy Checklist-Revised (PCL-R) is a widely used tool for the assessment of psychopathy, developed by Canadian psychologist Dr. Robert Hare. Psychopathy is a personality disorder characterized by a lack of empathy, shallow emotions, and manipulative behavior.
The PCL-R consists of a 20-item checklist, each of which is rated on a three-point scale (0, 1, or 2) based on the presence or absence of certain personality traits or behaviors associated with psychopathy. The 20 items are divided into two main categories:
- Personality traits: These items reflect long-term patterns of behavior, attitudes, and personality traits associated with psychopathy, including superficial charm, grandiosity, pathological lying, and lack of remorse or guilt.
- Antisocial behaviors: These items reflect specific behaviors associated with psychopathy, such as impulsivity, criminal versatility, and a history of juvenile delinquency.
A score of 30 or higher (out of a maximum of 40) on the PCL-R is generally considered indicative of psychopathy. However, it is important to note that the PCL-R should only be used by trained professionals and is just one tool among many used to assess personality disorders.
