Hare Psychopathy Checklist-Revised (PCL-R)
Developed to assess symptoms of psychopathy, the Hare Psychopathy Checklist-Revised (PCL-R) is a diagnostic tool which allows people to rate their psychopathic or antisocial habits. The PCL-R is used for legal, clinical, or research purposes as a indicator of potential risk posed by subject or prisoners.
Two parts are include the Hare PCL-R test: a interview and a review of the subject’s file records and history. During the assessment, the administrator answers a 20-item test measuring psychopathic traits. Completion time is 90 to 120 minutes. The second edition (or revised edition) is the current version of the test.

Reliability and Validity
The Hare Psychopathy Checklist is an established instrument for measuring psychopathy. Hare’s used a sample of 4,981 prison inmates and 1,246 inmates to calculate an alpha coefficient of 0.87 for both. Inter-rater reliability was also very high according to Rogers (2001). For a 5-year time period, the test-retest coefficient was presented at 0.89 (Schroeder, Schroeder, and Hare, 1983). Validity has been supported factor analysis studies (Hare, Harpur, Hakistan, Forth, & Hart, 1990) using samples of prisoner and forensic inpatients.
