The scale was developed to measure four factors labeled affective responsiveness, cognitive responsiveness, interpersonal manipulation, and egocentricity. Each subscale consists of five items measured using “agree” (1) and “disagree” (0) format (i.e., a trait is either present or absent). Total scale scores range from 0 to 20, whereas subscale scores range from 0 to 5. Higher scores indicate increased levels of psychopathic personality traits (i.e., increased egocentricity and interpersonal manipulation and increased deficits in affective and cognitive responsiveness).
