Which core traits exemplify psychopathic personality disorder is a hotly debated question withinpsychology, particularly regarding the role of ostensibly adaptive traits such as stress immunity, social potency, and fearlessness. Much of the research on the inter-relationships among putatively adaptive and more maladaptive traits of psychopathy has focused on the factor structure of the Psychopathic Personality Inventory (PPI) and its revision, the Psychopathic Personality Inventory – Revised (PPI-R). These instruments include content scales that have coalesced to form 2 higher-order factors in some (but not all) prior studies: Fearless Dominance and Self-Centered Impulsivity. Given the inconsistencies in prior research, we performed a meta- analytic factor analysis of the 8 content scales from these instruments (total N > 18,000) and found general support for these 2 dimensions in community samples. The structure among offender samples (e.g., prisoners, forensic patients) supported a three-factor model in which the Fearlessness content scale uniquely loaded onto Self-centered Impulsivity (rather than Fearless Dominance). There were also indications that the Stress Immunity content scale had different relations to the other PPI scales in offender versus community samples. We discuss the theoretical and diagnostic implications of these differing factor structures for the field of psychopathy research.

This study is designed to test the equivalency of the paper format of the Psychopathic Personality Inventory-Revised (PPIR) with a computerized (online) version. It is hypothesized that the psychometric properties of the PPI-R would continue to hold when the administration format was changed from paper to computer. A total of 124 respondents participate in the study. Participant scores on all 15 of the PPI-R scales are found to be similar, as are all internal scale consistencies. Test-retest reliabilities for scores on the PPI-R Overall Total, Factors, and Content scales range from r = .76 (Coldheartedness) to r = .93 (PPI-R Total). The computerized format also allows for both more efficient scoring (i.e., no hand coding) and more complete responding (i.e., less missing data).

Das Psychopathic Personality Inventory Revised (PPI-R) wurde bisher anhand der Daten gesunder, nicht straffälliger Probanden validiert. Die vorliegende Untersuchung überprüft die Validität des PPI-R für Straftäterstichproben. Die PPI-R Werte von 152 männlichen Patienten des Maßregelvollzugs, 65 Strafgefangenen und 214 männlichen Studenten wurden verglichen. Es wurden Reliabilitätskoeffizienten sowie Korrelationen mit der PCL-R berechnet. Es ergaben sich gute Reliabilitätskoeffizienten in der forensischen und der Strafgefangenen-Stichprobe. Die forensischen Patienten unterschieden sich signifikant von der gesunden Gruppe im Gesamtwert des PPI-R. Der PPI-R Gesamtwert und die PCL-R sowie deren Faktoren korrelierten signifikant. Obwohl die Gütekriterien des PPI-R auch in Straftätergruppen repliziert werden konnten, legen die Ergebnisse die Verwendung spezifischer Referenzwerte nahe. Einschränkungen des Einsatzes im Rahmen von prognostischen Aussagen sind zu beachten.
