Facets of psychopathy, Axis II traits, and behavioral dysregulation among jail detainees.

Forensic evaluations of offender populations often consider psychopathy as an integral component of these consultations. Vexing issues remain of whether psychopathic traits should be evaluated consistently irrespective of demographic characteristics (e.g. gender), comorbidity (e.g. other Axis II pathology), or setting (e.g. jail or community). The current study examined gender differences for psychopathy and Axis II traits in a nonreferred jail sample of predominantly nonviolent offenders. Participants with moderate to high levels of psychopathy evidenced substantial comorbidity, especially with Cluster B personality disorders. Facets of psychopathy and Axis II traits varied substantially across both genders. In addition, the research evaluated Lynam's Hyperactivity, Impulsivity, and Attention difficulties (HIA) model of psychopathy. These initial data found little support for the HIA model in this jail sample. In testing competing hypotheses, the HIA model was substantially better at predicting Cluster B traits than psychopathy per se. 2007 John Wiley & Sons, Ltd
