abstract="The Psychopathy Checklist—Revised (PCL-R) is a frequently used and well-validated measure of psychopathy but is relatively time-intensive and expensive to administer. The Psychopathic Personality Inventory (PPI) is a self-report measure that provides a less time-intensive and less expensive method for identifying psychopathic individuals. Using three independent samples and two different versions of the PCL (i.e., PCL-R, PCL:SV), the authors evaluated the extent to which the PPI and PCL overlap in their measurement of the psychopathy construct. Across three studies, PPI total and Factor 2 scores correlated moderately to strongly with PCL total and Factor 2 scores. Results for PPI and PCL Factor 1 scores were less positive. These findings raise important questions concerning the integration of results obtained using alternative psychopathy assessments.<p />",
