Poythress, Norman G.; Lilienfeld, Scott O.; Skeem, Jennifer L.; Douglas, Kevin S.; Edens, John F.; Epstein, Monica; Patrick, Christopher J. – Assessment, 2010
Two self-report measures of psychopathy, Levenson's Primary and Secondary Psychopathy scales (LPSP) and the Psychopathic Personality Inventory (PPI), were administered to a large sample of 1,603 offenders. The most widely researched measure of criminal psychopathy, the Hare Psychopathy Checklist-Revised (PCL-R), served as a provisional referent…

Peer reviewed Peer reviewed

Edens, John F.; McDermott, Barbara E. – Psychological Assessment, 2010
Although the construct of psychopathy is frequently construed as a unitary syndrome, the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) and its revision, the PPI-R (Lilienfeld & Widows, 2005), are composed of 2 scales, termed Fearless Dominance (FD) and Self-Centered Impulsivity (SCI), which appear to reflect orthogonal…

Further Evidence of the Divergent Correlates of the Psychopathic Personality Inventory Factors: Prediction of Institutional Misconduct among Male Prisoners
Peer reviewed Peer reviewed

Edens, John F.; Poythress, Norman G.; Lilienfeld, Scott O.; Patrick, Christopher J.; Test, Amy – Psychological Assessment, 2008
Recent evidence suggests that 2 largely orthogonal dimensions underpin the latent construct assessed by the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996): Fearless Dominance (PPI-I) and Impulsive Antisociality (PPI-II). Relatively few data exist on the correlates of these 2 dimensions in offender samples, however. The…

Patrick, Christopher J.; Edens, John F.; Poythress, Norman G.; Lilienfeld, Scott O.; Benning, Stephen D. – Psychological Assessment, 2006
Much of the research on psychopathy has treated it as a unitary construct operationalized by total scores on one (or more) measures. More recent studies on the Psychopathic Personality Inventory (PPI) suggest the existence of two distinct facets of psychopathy with unique external correlates. Here, the authors report reanalyses of two offender…

Effect of Response Distortion on the Assessment of Divergent Facets of Psychopathy
Peer reviewed Peer reviewed
Direct linkDirect link
Edens, John F. – Assessment, 2004
Recent evidence suggests that the Psychopathic Personality Inventory (PPI) is composed of two orthogonal factors, one representing traits such as dominance and low anxiety (PPI-I) and a second that reflects more socially deviant aspects of psychopathy (PPI-II). To assess whether response sets differentially affect these factors, the present…
