Cleckley Global Rating Scale (CGR)

The Cleckley Global Rating Scale (CGR) provides a global rating of the extent to which subjects meet Cleckley's description of the prototypical psychopath. Based on interview and file information, subjects are rated using the three-point scale listed below, on 15 of the 16 characteristics Cleckley used to describe psychopathy. Examples of these characteristics include: superficial charm and good intelligence, absence of nervousness or psychoneurotic manifestations, unreliability, lack of remorse or shame, pathologic egocentricity and incapacity for love, and, failure to follow any life plan. The CGR includes a Total Score which is the sum of the characteristic ratings, and a Global Rating (7-point Likert-scale), of the extent to which raters are confident that the subject is or is not a psychopath according to Cleckley's criteria.
