Empirical research concerning the reliability and predictive validity of the juvenile psychopathy construct, as assessed by the Psychopathy Checklist: Youth Version (PCL: YV; Forth et al, 2003) is reviewed. The results of an updated meta‐analysis (k = 38) investigating the interrater reliability of the PCL: YV are presented, along with an examination of meta‐analytic findings on the predictive accuracy of the tool. Considerations with respect to gender, ethnicity and development are explored. Some discussion points are offered regarding potential clinical applications of the construct of juvenile psychopathy and the PCL: YV with violent and other criminally adjudicated youths.

The purpose of this paper is to examine the structure of juvenile psychopathy, as measured by the Psychopathy Checklist: Youth Version (PCL: YV).

Using a sample of 2,042 male youths from the USA, Canada, and the UK, the study was a conceptual replication of Bishopp and Hare’s (2008) multidimensional scaling (MDS) analysis of adult male offenders assessed with the Psychopathy Checklist-Revised.

The scaling analyses generally replicated those obtained by Bishopp and Hare, providing support for a multidimensional, four-factor model of juvenile psychopathy similar to that obtained with adults. However, a small number of items fell outside their predicted regions. Slight differences in the structure of juvenile psychopathy were found for incarcerated and supervised samples of youth, with the four-factor model breaking down slightly for the supervised sample. Item misplacements may indicate that certain items on the PCL: YV are being misinterpreted, reflect different dimensions for different samples, or cannot be reliably measured. Future research should examine these possibilities, with special attention being paid to supervised samples.

To the authors’ knowledge, this is one of the first known attempts to use MDS analysis to examine the psychopathy structures that emerge for male juvenile offenders. The greater nuances afforded by using MDS offer a more comprehensive understanding of psychopathy between incarcerated and supervised youth using the PCL: YV.

The PCL‐R has been heralded as the ‘unparalleled’ (Salekin et al, 1996) risk assessment tool for assessing risk of violent and non‐violent recidivism. In the UK, the PCL‐R looks likely to become an industry standard assessment in psychological evaluation of individuals thought to have a dangerous and severe personality disorder. However, current knowledge about the PCL‐R is unsatisfactory, and a number of issues need to be addressed before clinicians can be confident in the use of this measure. This paper highlights these issues from the perspective of the practising clinician. Questions are raised about the theoretical, methodological and treatment implications of the use of the PCL‐R. Future research needs are established in this context of caution over the use of the measure in routine clinical and academic assessment.

This paper aims to provide a critical review of the psychopathy literature, with a particular focus on recent research examining the relationship between psychopathy and various forms of criminal behaviour.

The authors provide an overview of the studies conducted to date. To identify relevant published studies for this review, literature searches were completed using Web of Science, Scopus, PsychINFO, and PubMed.

Substantial empirical research exists to suggest that psychopathy is a robust predictor of criminal behaviour and recidivism. Furthermore, considerable support for the assertion that the violence perpetrated by psychopathic offenders is more instrumental than the violence committed by other offenders was found. In addition, some research suggests that the greater use of instrumental violence among psychopathic offenders may be due to the interpersonal/affective traits of psychopathy, and not the impulsive/antisocial traits.

The current paper is the first to provide an in‐depth review of the literature examining the association between psychopathy and criminal offending with a particular focus on violent and homicidal behaviour.

The purpose of this paper is to explore the relationship between psychopathic features as measured with the Psychopathy Checklist: Youth Version (PCL:YV) and behavioural and emotional functioning in young female offenders in custody.

This is a quantitative interview study investigating the relationship with psychopathic traits, measured with the PCL:YV (Forth et al., 2003), and different psychological characteristics as well as AD/HD, self-harm, and childhood trauma in adolescent offenders across genders. Data were collected from a sample of 40 female and 40 male adolescents who were incarcerated in Victoria, Australia.

Results indicated that the behavioural subscales of the PCL:YV were associated with externalising behaviours possibly underpinned by histories of abuse and substantiated child protection incidences. The presence of AD/HD was strongly associated with affective deficits suggesting that the PCL:YV may be identifying young females with AD/HD rather than core psychopathic traits. Findings also indicate that female-specific manifestations of manipulation are likely being misidentified as behavioural phenomena precluding clinical recognition as a core interpersonal trait. Significant dissimilarities with a young male comparison group were identified and are discussed within.

The sample size is very small and the results should be seen as an indication rather than generalising.

Studies on female juvenile offenders is rare and this study adds to the literature on the construct of psychopathy and its relationship to psychosocial factors as well as associations with AD/HD, self-harm, and childhood trauma, among incarcerated adolescents.

Increasingly, it is recognized that (larger) organizations have many employees who present with corporate psychopathy (i.e. a milder version of anti-social personality disorder). Importantly, such a disorder contributes to the presence of deviant workplace behavior. Organizations must therefore adapt its practices to both identify and manage employees who either present with, or have tendencies toward, corporate psychopathy. As a means of developing a guiding framework for organizational adaptation, this two part paper offers two reviews of relevant research. The first revolves around the body of knowledge regarding corporate psychopathy and the primary, established behavioral method of identifying its presence; the second is a brief review on physiological measures that can complement current gold standards. The paper aims to discuss these issues.

A range of published empirical and practitioner research articles were reviewed to first, elaborate on anti-social personality disorder and corporate psychopathy; second, showcase the efficacy of the currently most accepted method of detecting psychopathic behavior – the Psychopathy Checklist (PCL); and third, highlight physiological methods of detecting psychopathic tendencies which may complement usage of the PCL – electroencephalography, measurement of galvanic skin responses, and electromyography.

First, deviant workplace behaviors cause losses of billions of dollars across all business organizations, and much of this behavior stems from corporate psychopaths in positions of leadership. Second, the PCL, while useful, can nonetheless yield sharp differences in the identification of psychopathy across different administrators of the test. Third, measures of physiological states show good reliability in discriminating psychopathic persons from non-psychopathic persons. Based on these findings, the authors propose guidelines for how to identify and mitigate the effects of corporate psychopathy for organizations.

The proposed guidelines must be tested in an empirical paper to measure their effectiveness.

The paper suggests an overall framework that may help leaders and organizational development practitioners identify the major factors which may be considered to safeguard against the potentially detrimental conduct of corporate psychopaths in their organizations.

This paper highlights the need to identify and ward against the presence of corporate psychopaths. There needs to be guidelines for organizations on how to identify and mitigate the effects of corporate psychopathy for organizations.

The suggestion of integrating physiological methods of detection with the PCL, as well as urging pro-active education of all employees as the symptoms and effects of corporate psychopathy, is the novel contribution of the paper.

The Psychopathy Checklist‐Revised is used in forensic and clinical settings to give an indication of the level of psychopathy an individual presents. The use of the PCL‐R with offenders with a learning disability (LD) is understudied. The current study aims to replicate a study by Morrissey (2003) which focused on the problems arising from assessing an LD service sample from Rampton Hospital. The results may suggest that the PCL‐R may be used reliably with offenders with low intellectual functioning.

The psychopathy checklist: youth version (PCL: YV) checklist is an assessment of youth psychopathic traits and is regularly validated by way of its associations with re-offending and violence. Yet existing research has been conducted with predominantly white Caucasian cohorts and extant evidence suggests that associations with recidivism are stronger in samples with greater proportions of white offenders. The paper aims to discuss these issues.

This study investigated the cross-cultural validity of the PCL: YV for an ethnically diverse Australian sample of 175 young male offenders in custody. Participants were assessed in custody with the PCL: YV and offending data were collected post-release for up to 18 months.

PCL: YV total and domain scores were comparable across ethnicity; however the instrument demonstrated stronger relationships with recidivism for Australian participants with an English speaking background compared to Indigenous and culturally and linguistically diverse participants.

The authors advocate the cautionary employment of the PCL: YV as a violence risk prediction instrument with minority young offenders regionally, pending further evidence.

This study addresses the capacity of the PCL: YV to predict violence across different ethnic groups. Cross-cultural youth psychopathy research is currently inadequate and existing studies suggest that the PCL: YV is a weaker predictor of violence in culturally diverse samples. This investigation provides much needed information on the capacity of the PCL: YV to extend to different ethnic groups who are represented Australia’s youth prison population. This is the first study of its kind regionally, and more importantly is the first PCL: YV study with an Indigenous Australian comparison group. This is particularly important given that Indigenous Australians are heavily overrepresented in Australia’s criminal justice system and require appropriate risk assessment measures to ensure they are not misclassified. Research such as this is now of particular interest given the recent judicial decision made in Ewert vs Canada.

The purpose of this paper is to develop a predictive model of criminal risk in civil psychiatric populations, by determining the relative impacts of psychopathy, drug use, impulsivity and intelligence on levels of criminality.

The sample consisted of 871 civil psychiatric patients, selected from the MacArthur Violence Risk Assessment Study, who had been diagnosed with a mental illness or personality disorder, and hospitalised less than 21 days. Each participant was administered the Hare Psychopathy Checklist Screening Version (PCL:SV), Barratt Impulsiveness Scale (BIS-11) and the Wechsler Adult Intelligence Scale (WAIS-R). In addition, information on background demographics, drug use and criminality was obtained via a self-report questionnaire.

Pearson correlations identified significant positive relationships between past arrests, psychopathy, impulsivity and drug use. Intelligence was negatively related to past arrests. Multiple regressions identified a significant main effect for Factor 2 psychopathy on past arrests when controlling for all covariates, but not for Factor 1 psychopathy, intelligence or impulsivity. Drug use and gender had small univariate effects.

It is suggested that future research investigates the influence of specific mental disorders on different types of offending.

By investigating predictors of criminal behaviour in civil psychiatric patients, the present study makes valuable contributions to the research literature, enhancing our theoretical understanding of the relationships between psychopathy and criminality/recidivism. It also has notable implications in applied practice, for example in the development and refinement of risk assessment methods.

The purpose of this paper is to explore the relationship between differences in performance and verbal intelligence quotients (PIQ and VIQ) and the four facet scores from the Psychopathy Checklist–Revised (PCL–R) (Hare, 2003).

Wechsler Adult Intelligence Scale (WAIS) and PCL–R facet scores provided by 181 male federal inmates as part of a forensic evaluation were analyzed with multiple regression, paired t-tests, and receiver operating characteristic (ROC) curves.

Of the four PCL–R facet scores, only elevations on Facet 4 (antisocial) produced a significant WAIS-Revised (Wechsler, 1981) PIQ over VIQ (PIQ>VIQ) effect. In addition, only Facet 4 achieved significant ROC accuracy and correlated with the PIQ>VIQ discrepancy after other potentially important variables were controlled. In a follow-up study of 46 male inmates, Facet 4 correlated negatively with the Verbal Comprehension and Working Memory indices of the WAIS–Third Edition (Wechsler, 1997) and accurately classified a significant portion of Perceptual Organization Index (POI)>WMI cases but not a significant portion of POI>VCI cases.

Verbal comprehension and executive function deficits are examined as possible explanations for the relationships observed in this study.

These results have potentially important implications for forensic assessment in that they suggest that only certain specific features of the psychopathy construct are related to the well-known PIQ>VIQ discrepancy.
