Psychopathic Personality Traits Scale (23-item)
The 23-item Psychopathic Personality Traits Scale is a self-report scale that measures various elements of psychopathic (or sociopathic) personality. It also tests more generally for problems of self-regulation, which is closely related to psychopathy, and is based on the five-factor model of personality, showing that measures of self-regulation and self-control are rough proxies for psychopathy. The Psychopathic Personality Traits Scale was developed as part of a study to examine the genetic foundations to psychopathic personality traits. Its items were generated from a list of items from the International Personality Item Pool. The scale has good internal consistency, with a Cronbach's alpha of 0.82. Test items are scored on a scale from 1 to 5, where 1 = "strongly agree," 2 = "agree," 3 = "neither agree nor disagree," 4 = "disagree," to 5 = "strongly disagree." 14 items are reverse-coded so that higher scores represent higher levels of psychopathic personality traits.
