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 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.

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.

Recent developments in the psychometric assessment of youth psychopathic traits suggest that the inclusion of a conduct disorder (CD) factor to the traditional three factors of the psychopathy construct may improve the incremental validity of these measures. The purpose of the current study is to examine whether the addition of a CD factor incrementally improves the ability of the Youth Psychopathic Traits Inventory Short version (YPI-S) to predict criminal recidivism.

A longitudinal quantitative research design was used with a sample detained male youth (N = 214, M_age = 16.4 years, SD_age = 1.3 years).

Results using the area under the curve analysis suggest that the inclusion of a CD factor slightly improves the capacity of the YPI-S to predict one-year general criminal recidivism, but it does not significantly increase its capacity to predict violent criminal recidivism. Results also indicate that a CD scale outperforms the YPI-S, even with an additional CD factor included, in terms of predicting one-year general and violent recidivism.

Self-reported youth psychopathic trait measures, even those that include a CD factor as a fourth factor, should be used with caution when the aim is to predict youth criminal recidivism.

To the best of the authors’ knowledge, this is the first study using a self-reported youth psychopathic traits measure with a CD factor to examine youth criminal recidivism.

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 investigate the impact of psychopathy factors and gang membership on moral disengagement while controlling for age, ethnicity, having run away from home, family member and/or friend arrests, substance misuse, parental physical fights, violence exposure (victimization and witnessing), and maternal warmth and hostility.

The research is based on data collected from serious juvenile offenders (n=769) as part of the Pathways to Desistance Study.

Six independent variables made a unique statistically significant contribution to the model: gang membership, age, gender, violence exposure, and psychopathy Factors 1 and 2. Psychopathy Factor 1 was the strongest predictor of moral disengagement.

Results indicate that youth with heightened psychopathic traits make greater use of strategies to rationalize and justify their harmful behaviour against others. Implications in relation to theory and previous studies are discussed.

The purpose of this paper is to present and provide a critical review of most recent studies inquiring into brain abnormalities in psychopathy.

The authors provide an overview of the findings of neurobiological studies conducted in the last five years. Publications chosen for review were found using Web of Science, PsycINFO and Scopus search engines.

Data in the literature reveal that psychopathy is associated with brain abnormalities in frontal and temporo-limbic regions, i.e. regions responsible for moral decision making, emotional processing and learning. Additionally, interactions between the brain areas have been identified as crucial for the development of psychopathic personality traits. Research findings suggest that the flow of impulses between the frontal cortex and temporo-limbic structures in psychopaths is significantly hindered.

The current paper provides an in-depth review of most recent neurobiological studies inquiring into brain abnormalities associated with psychopathic personality traits. Moreover, a particular attention has been paid to identifying abnormalities in brain structures not previously studied in relation to psychopathy (e.g. mirror neuron system, white matter connections).

The purpose of this study was to survey practitioners’ use and perceptions of psychopathy assessments in Canadian forensic psychiatric settings. Psychopathy assessments are widely used in forensic settings to inform decisions about sentencing, placement, rehabilitation and parole. Recent empirical evidence suggests that the utility of psychopathy assessments might be overestimated, leading to a debate about their legal and ethical justification. However, one shortcoming of these discussions is that they rely heavily on anecdotal evidence about how exactly psychopathy assessments influence forensic decisions, due to a general lack of survey data on field uses. Some data are available in European and American contexts, but little is known about Canadian clinical practice.

To address this shortcoming in the literature, the authors conducted a pilot study of practitioners in forensic psychiatric units in Ontario (N = 18), evaluating their use of psychopathy assessments, reporting habits and their perceptions of psychopathic offenders.

Practitioners reported that they primarily used the Hare Psychopathy Checklist-Revised (PCL-R) as a risk assessment tool, often in combination with other tools. Most clinicians reported using psychopathy assessments infrequently, that there was a low base rate of psychopathic offenders and their attitudes and beliefs about psychopathy were generally consistent with the empirical literature.

This pilot study provides novel insights into the use of psychopathy assessments in Canadian forensic psychiatry with the potential to inform current debates.

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.
