The current study reports validation results for the Psychopathic Personality Inventory (PPI) and its subscales, and for a newly developed PPI-Short Form (PPI-SF) in forensic and non-forensic populations. We also provide criterion reference scores for the PPI and the PPI-SF. In Study 1, we used PPI data from 1,065 participants and supplementary PCL-R data from a subsample of 91 forensic offenders. Mokken scale analysis was used to construct the PPI-SF. In Study 2, PPI-SF and PCL-R data were collected from 60 participants. The study yielded promising but preliminary support for the construct validity of the PPI and the PPI-SF. The PPI-SF is of interest for risk assessment because of its (a) strong relationship with the PCL-R total score and (b) subscales known for their predictive value for violence and criminal recidivism.
