Four-facet PCL-R structure and cognitive functioning among high violent criminal offenders.

High violent inmates (N = 126) were administered the Psychopathy Checklist-Revised (PCL-R; Hare, Clark, Grann, & Thornton, 2000; Hare et al., 1990) and neuropsychological measures. No significant correlations were present between the overall PCL-R score and 14 cognitive measures. A violence score, computed as the total number of violent acts across all situations and types, was significantly correlated with the PCL-R total score and Facet 2 but not with the other three facets. Our data suggest that Facet 2 elevations may prove relevant to violence risk assessment; this link, however, needs further exploration with larger samples.
