Psychometric Properties of the Psychopathic Personality Inventory in a Non-criminal Population
The Psychopathic Personality Inventory (PPI) is a self-report measure which was created 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 Externalization, Impulsive Nonconformity and Stress Immunity. The hypothesized relationships and factor structure of this study follow the theory of psychopathy as being a disorder rooted in antisocial behaviors (often aggressive and impulsive in nature) and inappropriate emotional reactivity (characterized as a lack in empathy and anxiety). A confirmatory factor analysis was done with an ethnically diverse undergraduate population to see if the two factor model is replicated—one showing impulsivity and aggression, and the second showing lack of empathy and anxiety.
