Aberrant psychopathy as a potential protective factor against posttraumatic stress disorder symptomatology

This study attempted to explore the potential correlation between the constructs of psychopathy and posttraumatic stress disorder susceptibility. Based on the relevant literature, it was hypothesized that there would be an initial positive but ultimately negative correlation between psychopathy as measured by the PCL:SV and PTSD symptomatology as indicated by Scale R of the MCMI-III. It was further hypothesized that higher PCL:SV total and Factor 1 scores would be more negatively correlated than would Factor 2 scores with MCMI-III Scale R scores. To this end archival data were extracted from psychological assessments of 45 adults as part of consideration into a prison diversion program. Current results indicate an insignificant negative correlation between all facets of the PCL:SV with MCMI-III Scale R. Various limitations and implications are discussed.
