The Psychopathy Checklist-Revised (PCR) is a 20-item scale scored from interview and file information. The PCR includes 2 factors. Factor 1 is a measure of Emotional Detachment (e.g., superficial charm, manipulativeness, shallow affectivity, absence of guilt or empathy). Factor 2 is a measure of Antisocial Behavior (deviance from an early age, aggression, impulsivity, irresponsibility, proneness to boredom). There is also a total score.
The PCR consists of 20 items that are rated on a three-point scale (from 0 to 2) based on the degree to which the personality/behavior of the subject matches the description of the item.
The PCR yields 2 primary scales and one total score. Description of the scales and item loadings are listed below. Scale scores are calculated as the sum of respective items. No items are reverse scored.
