Assessing the External Correlates of Alternative Factor Models of the Psychopathic Personality Inventory–Short Form Across Three Samples Academic Article uri icon


  • This study investigated various theoretically relevant correlates of a short form of the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) using archival data from large undergraduate, foster care, and juvenile offender samples. External correlates of the 2 primary scales (PPI-I and PPI-II) and the Coldheartedness subscale were for the most part consistent with prior findings. Analyses for an alternate factor model in which the Fearlessness subscale loaded onto PPI-II (rather than PPI-I) resulted in relatively few substantial changes to the pattern of correlations with criterion measures, but a third factor that included the Coldheartedness and Carefree Nonplanfulness subscales functioned differently than Coldheartedness alone in these data.
