This investigation evaluated the construct validity of the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996), a self‐report measure designed to assess psychopathy. One hundred and two incarcerated females were administered the Kaufman Brief Intelligence Test (K‐BIT), an oral alcohol and drug screening measure, a demographic interview, the Minnesota Multiphasic Personality Inventory—2 (MMPI‐2), the Psychopathy Checklist—Revised (PCL‐R), and the PPI. There were significant correlations among the PPI, MMPI‐2 scales, and the PCL‐R. In addition, the correlations between the PPI and the separate PCL‐R factors were not significantly different from each other, indicating that the PPI is assessing both facets of the psychopathy construct to some extent. A high correlation between the PPI and the DSM‐IV criteria, which assesses adult antisocial behaviors, revealed adequate concurrent validity. Nonsignificant or negligible correlations between the PPI and the MMPI‐2 scales provided some support for discriminant validity. The results are discussed with respect to the clinical and forensic utility of the PPI, the limitations of the study, and the need for further research. Copyright © 2005 John Wiley & Sons, Ltd.
