Further Validation of the Psychopathic Personality Inventory among Offenders: Personality and Behavioral Correlates
Digital Object Identifier (DOI)
The Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) is a relatively new self-report measure that has shown considerable promise as an index of psychopathic traits in both nonoffender and offender samples. The present study examined the construct validity and predictive utility of the PPI by examining its association with theoretically relevant scales of the Personality Assessment Inventory (PAI; Morey, 1991) among 60 male prison inmates, and its ability to predict institutional misbehavior in an expanded sample (n = 89). As expected, correlations with the PAI scales were highest for the Antisocial Features (ANT) and Aggression (AGG) scales (rs = .68 and .57, respectively). The PPI also predicted various forms of nonviolent and physically aggressive disciplinary infractions significantly better than chance (point biserial correlations ranging from .26 to .37).
