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

ABSTRACT: Introduction: Psychopathy is characterized by a pattern of constant affective deficit and lack of respect for other people's rights and social norms. The Psychopathy Check-List Revised (PCL-R) is an instrument of measurement composed of 20 items and it is one of the most used in psychopathy and antisocial personality disorder research. Objective: To validate the PCL-R in Colombian male inmates. Methods: Two translations into Spanish and two back-translations for each of the items were done. The instruction manual was also translated into Spanish and back-translated. Face validity was assessed by a group of experts. Content validity was examined as well as internal consistency, test-retest and inter-rater reproducibility. Results: In the factor analysis for the content validity, four domains were found which explained 61.1% of the variance. The internal consistency was high (Cronbach's Alpha=0.94). Similarly, the test-retest and inter-rater reproducibility were ICC=0.83, 95% CI: 0.68-0.91 and ICC=0.83, 95% CI: 0.86-0.96, respectively. Conclusions: The Spanish version of the PCL-R for Colombian male jail inmates shows good psychometric properties.01/2008; 37(4):564-579.

ABSTRACT: This study examines the relationship of Hare's psychopathy scores (PCL-R) with attention deficit hyperactivity disorder (ADHD) diagnosis and brain dysfunction measures in a sample of 1,695 adult male sexual, violent, and nonviolent offenders. ADHD and brain dysfunction were significantly more common among psychopaths than non-psychopaths. Psychopaths showed more neurological disorders and early problems with learning disorders. Although psychopathy is characteristically considered to be an untreatable and dangerous condition, its significant association with ADHD and brain dysfunction indicates that there are important treatment paths that should be explored and that early treatment should be an important consideration in prevention of adult criminal behavior.Journal of Forensic Psychology Practice 05/2010; 10(3):177-200.

ABSTRACT: Executive dysfunction in those high on traits of psychopathy has often been reported, with many disagreements as to the nature of the dysfunction. We aimed to see if tests of planning and rule acquisition/adherence would discriminate those high on psychopathic traits. A battery of executive function tests (Tower of London, Brixton Spatial Anticipation, and Hayling Sentence Completion Tasks) was given to 28 British male prisoners. Psychopathy was measured using the Psychopathy Checklist-Revised. High psychopathy was related to reduced planning in the Tower of London Test and poor rule-adherence on the Brixton Test. Other tests of executive function were not related to psychopathy. The results appear supportive of the notion that function of the orbitofrontal cortex (OFC) is dysfunctional in psychopathy whilst that of the dorsolateral prefrontal cortex (DLPFC) is normal and suggest that impulsivity in those high on psychopathy traits impedes planning and rule following. We suggest the adapted Tower of London Test and the Brixton Test could be useful objective measures of this type of impulsivity in offenders which could help identify key treatment goals.Psychiatry Research 07/2014; 220(1-2).
