CORRESPONDENCE BETWEEN THE PSYCHOPATHIC PERSONALITY INVENTORY AND THE PSYCHOPATHIC PERSONALITY INVENTORY-REVISED: A Look at Self-Reported Personality Traits

The authors examined the correspondence between the Psychopathic Personality Inventory (PPI) and a recent revision of this measure, the Psychopathic Personality Inventory-Revised (PPI-R) in a sample of 85 male and female offenders in a community-based residential drug treatment program. Participants completed the PPI and PPI-R along with self-report measures of narcissism, aggression, emotional intelligence, and negative emotionality. Analyses focused on the associations between the total and factor scores, as well as content scale scores across the two measures, and the similarity between parallel indices from these measures in their associations with external criteria. Results suggest that findings from prior research examining PPI associations with criterion measures in the self-report domain of personality traits can reasonably be generalized to the PPI-R.
