Although considerable research on psychopathy has been conducted over the past 30~years, relatively few studies have examined key issues related to potential ethnic differences in this constellation of socially maladaptive personality traits. Given recent sociopolitical and scientific developments, an issue of considerable debate is whether Black individuals possess “more” traits of psychopathy than do Whites. To address this issue, a meta-analysis of differences between these groups' scores on… 
Do black and white youths differ in levels of psychopathic traits? A meta-analysis of the psychopathy checklist measures.

Identifying Subtypes of Criminal Psychopaths
Cluster analysis is used to replicate and extend findings to an independent sample and a Psychopathy Checklist—Revised factor model that reduces predictor-criterion contamination, showing that psychopathy subtypes are replicable across methods.

Results of the multigroup invariance analyses indicated that these measures are invariant across sex and between Hispanic and Black youth and parent-report version of the Inventory of Callous-Unemotional Traits.
Inter-rater reliability of the PCL-R total and factor scores among psychopathic sex offenders: are personality features more prone to disagreement than behavioral features?
Despite considerable support for the inter-rater reliability of the Hare Psychopathy Checklist--Revised (PCL-R; Hare, 1991, 2003) in research contexts, there is increasing concern that scores from

Part one of the thesis reviews the literature on whether antisocial personality disorder (ASPD) and psychopathy represent distinct categories. This question was addressed by identifying studies with
Youth Psychopathy and Criminal Recidivism: A Meta-Analysis of the Psychopathy Checklist Measures
Recidivism data for the Psychopathy Checklist measures across 21 non-overlapping samples of male and female juvenile offenders was meta-analyzed and psychopathy was significantly associated with general and violent recidivism, but negligibly related to sexual recidivist in the few studies examining this low base rate outcome.


Assessment of psychopathy as a function of age.
The results suggest that age-related differences in traits related to impulsivity, social deviance, and antisocial behavior are not necessarily paralleled by differences in the egocentric, manipulative, and callous traits fundamental to psychopathy.

The primary goals of this set of studies were to develop, and initiate the construct validation of, a self-report measure that assesses the major personality traits of psychopathy in noncriminal populations and clarify the nature of these traits via an exploratory approach to test construction.
