Evaluating the Screening Version of the Hare Psychopathy Checklist—Revised (PCL:SV): An item response theory analysis.

Abstract

was developed to complement the Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991), and for use outside forensic settings. The PCL:SV takes less time to administer and requires less collateral information than the PCL-R. An item response theory approach was adopted to determine similarities in the structural properties of the 2 instruments and whether the PCL:SV could be regarded as a short form of the PCL-R. Eight of the 12 items in the PCL:SV were strongly parallel to their equivalent PCL-R items. Of the 4 items PCL:SV items which differed from their equivalent PCL-R items, all 4 were found to be equal or superior to their equivalent PCL-R items in terms of discrimination. The analyses confirmed previous results that the interpersonal and affective features of psychopathy have higher thresholds than do the impulsive and antisocial behavioral features; individuals have to be at a higher level of the psychopathic trait before the interpersonal and affective features become evident. The PCL:SV is an effective short form of the PCL-R.

Prevalence and correlates of psychopathic traits in the household population of Great Britain

“…Following adjustments, there were significant associations between PCL: SV and Axis II disorders, similar to those previously demonstrated in forensic samples (Cooke et al, 1999;Ullrich & Marneros, 2007). These studies have indicated that PCL-R and PCL: SV total scores correlate most strongly with antisocial, borderline, histrionic, and narcissistic scores.…”

“…In this study, persons with schizophrenia, depressive episodes, mixed anxiety and depressive disorder, generalized anxiety disorder, and phobias did not have raised psychopathy scores, corresponding to offender samples which have not demonstrated associations with affective disorders (Cooke et al, 1999;Hare, 2003). In offender samples, measures of anxiety tend to have low, negative correlations with the PCL-R.…”

“…The two instruments are highly correlated and measure the same construct (Cooke, Michie, Hart & Hare, 1999;Guy & Douglas, 2006). Although not included in the ICD or DSM classifications, analyses of traits associated with personality disorders reveal a dimension remarkably similar to the personality features that constitute psychopathy (Blackburn & Coid, 1998; Marneros, 2004;2007).…”

Response inhibition in the parametric Go/No-Go task in psychopathic offenders

“…The factor structure of the PCL-R as well as its' screening version, the Psychopathy Checklist: Screening Version (PCL:SV; Hart et al, 1995), consists of four facets, measuring the interpersonal (tendency to display superficial, grandiose and deceitful behaviours), affective (lack of remorse and empathy, and individuals not accepting responsibility for their own actions), impulsive lifestyle (impulsivity, irresponsibility and a lack of goals) and antisocial behavioural characteristics (poor behavioural controls, as well as adolescent and adult antisociality) of psychopaths (Cooke et al, 1999;Hill et al, 2004;Vitacco et al, 2005). Given the incorporation of impulsive behaviours into the definition of psychopathy, explicitly in the lifestyle facet, one might expect psychopaths to express enhanced levels of impulsivity when measured under experimental conditions, but the evidence for elevated impulsivity levels in this context is currently inconclusive (Kiehl et al, 2000;Verona et al, 2012;But see: LaPierre et al, 1995;Varlamov et al, 2011).…”

Avaliação de risco de violência em Psiquiatria Forense

“…Trata-se de uma versão compacta (screening version) do PCL-R (Cooke et al, 1999). Ela é composta de 12 itens e mostrou-se válida para a previsão de violência institucional e comunitária.…”
