Figuring out la femme fatale: conceptual and assessment issues concerning psychopathy in females.

Despite the growing number of studies on psychopathy in females, the core characteristics of this personality disorder among females remain uninvestigated. Most studies on psychopathy in females have attempted to understand the disorder by applying male criteria to adult females: they have ignored putative gender differences in the constitution and expression of this disorder. Several issues require resolution: first, whether practitioners apply the same criteria to diagnose psychopathy in women, second, whether the instruments used to assess psychopathy are tapping the same construct across gender, third, whether the same types of behavioral expression of key traits are similar across genders, and fourth, whether the diagnosis possesses the same forensic utility across genders. The relevant literature is reviewed and issues of design and analysis are considered. Copyright (c) 2005 John Wiley & Sons, Ltd.
