The validity of the psychopathic personality inventory--revised in a community sample.
Research on the Psychopathic Personality Inventory-Revised (PPI-R) has revealed two factors: Fearless Dominance, and Self-Centered Impulsivity. This study examined the validity of these PPI-R factors in a community sample (N = 675). First, confirmatory factor analyses did not support the two-factor structure. Second, the PPI-R factors showed good convergent and discriminant validity with two other self-report measures of psychopathy, that is, the Youth Psychopathic Traits Inventory and Levenson's Self-Report of Psychopathy. Third, PPI-R factors exhibited good external validity in relation to various theoretically relevant correlates. The results indicate that the PPI-R factors have good convergent, discriminant, and external validity, but confirmatory factor analysis raises concerns about the robustness of the two-factor structure.
