The Psychopathic Personality Inventory (PPI) is a self-report measure which was created by Lilienfeld and Andrews (1996) to identify the personality traits of psychopathy in noncriminal populations. These personality traits were grouped into eight subscales in the PPI including Machiavellian Egocentricity, Social Potency, Coldheartedness, Carefree Nonplanfulness, Fearlessness, Blame Extemalization, Impulsive Nonconformity and Stress Immunity. In this study, the relationship between the PPI and four theoretically related concepts (psychopathy, empathy, sensation seeking and driving anger) were examined to evaluate its concurrent and construct validity. A positive correlation was found between the PPI and the Self-Rep0l1 Psychopathy Scale, the Driving Anger Scale, the Amett Inventory of Sensation Seeking and the Interpersonal Reactivity Index. Contrastingly, a negative correlation was found between the PPI's Coldheartedness Subscale and the Interpersonal Reactivity Index. The results of this study have helped to further the conceptualization of the successful psychopath and the validity of the PPI in its assessment.
