Psychopathic Traits in Youth: Is There Evidence for Primary and Secondary Subtypes?

The current study employed model-based cluster analysis in a sample of male adolescent offenders (n = 94) to examine subtypes based on psychopathic traits and anxiety. Using the Psychopathy Checklist: Youth Version (PCL:YV; Forth et al. 2003) and the self-report Antisocial Process Screening Device (APSD; Caputo et al. 1999), analyses identified three clusters in males that varied in the severity of psychopathic traits (low, moderate, and high) and anxiety. The high psychopathic group exhibited more negative personality traits and was judged to be at greater risk for dangerousness whereas the low psychopathic group exhibited more positive personality traits and was judged to be at lower risk for dangerousness. Implications regarding potential developmental differences between adolescent and adult psychopathy, as well as treatment considerations are discussed.     

Child Psychopathy: Theories,Measurement, and Relations with the Development and Persistence of Conduct Problems

To develop more accurate explanatory and predictive models of child and adolescent conduct problems, interest has grown in examining psychopathic traits in youth. The presence or absence of these traits may help to identify unique etiological pathways in the development of antisocial behavior. The current review provides a detailed summary and analysis of (a) the conceptualization and measurement of child and adolescent psychopathy, (b) research on relations between psychopathic traits and a range of conduct problems and associated variables, (c) efforts to utilize data on child and adolescent psychopathy to delineate a subgroup of youth whose conduct problems share a relatively homogenous etiology and developmental trajectory, and (d) current challenges and limitations in the study of youth psychopathy and directions for future research efforts. Specific sections include the origins of the youth psychopathy construct, conceptualization and measurement, relations between psychopathic traits and conduct problems, relations between measures of psychopathy and measures of individual and contextual variables, efforts to identify a unique subgroup of children with conduct problems using psychopathic traits, and finally, challenges that face the field and goals for the next generation of research.     

Conceptualizing psychopathic traits from an evolutionary-based perspective: An empirical study in a community sample of boys and girls

Although psychopathy has historically been associated with a lack of emotion, recent research has suggested that psychopathy may represent a tendency to externalize the experience of unpleasant emotions, including shame, which could be seen as an adaptive strategy within an evolutionary framework. However, more empirical research is needed to build on this argument. This study tested a novel evolutionary-based model involving pathways associating the impact of harsh rearing experiences (warmth and safeness experiences and traumatic shameful experiences) with psychopathic traits as well as the indirect effects of external shame and shame coping strategies in this association. This study also tested the invariance of this model across gender. A youth community sample (N = 703; 58.9% girls) completed self-report questionnaires on the impact of harsh rearing experiences, external shame, shame coping strategies, and psychopathic traits. The results suggested that the impact of harsh rearing experiences was directly and indirectly (through external shame and shame coping strategies) associated with psychopathic traits. The model partially explained the endorsement of psychopathic traits in boys and girls, although gender differences were found in some of the pathways. These findings offer support for conceptualizing psychopathic traits as an adaptive strategy to cope with the impact of harsh rearing experiences, opening new perspectives for prevention and treatment.

     

Socioeconomic Status and Psychopathic Traits in a Community Sample of Youth

The current study aims to address socioeconomic status (SES) as a moderating variable between psychopathic traits and conduct problems in a sample of 2432 Dutch adolescents (M_age?=?14.50 years, SD?=?1.67, 56% male). Both family and neighborhood SES were measured, with income as a proxy for the level of SES. There were small but significant positive correlations between the behavioral and interpersonal dimensions of psychopathy and family SES, a small but significant negative correlation between the affective dimension and neighborhood SES, and a small and significant positive correlation between neighborhood SES and the behavioral dimension of psychopathy. Results further showed that the relations between youth psychopathic traits were moderated by neither family SES nor neighborhood SES. The results suggest that the relations between psychopathic traits and conduct problems are equally strong for lower and higher SES youth. Taken together, these findings warrant the conclusions that SES does not play a role as a moderator in the relation between psychopathy and conduct problems.     

„Psychopathy“ im Kindes- und Jugendalter

The term psychopathy is defined as a severe personality pathology, which is characterized by extreme aggressive, antisocial and violent behavior as well as affective and interpersonal deficits. In recent years, research into the construct of psychopathy has often focused on the incidence and detection of such pathologies in children and adolescents. In this context, a point of interest is to explore the course and stability of psychopathic personality dimensions throughout youth. Results demonstrate clear evidence for the occurrence of personality traits characteristic for psychopathy in early childhood and adulthood, which facilitates early detection with the aid of age-specific diagnostic instruments.The distinct correlation between psychopathy and severe, repeated and largely treatment refractory violence, which results in substantial public damage, calls for further research in children and adolescents in order to define the construct of psychopathy more precisely, to further illuminate underlying pathologies and consequently develop more specific typologies and effective treatment strategies. To that end, it is of particular importance to correctly capture dimensional factors of psychopathy in youth and to examine their stability throughout stages of adolescent development.     

Screening for adolescent psychopathy among at-risk youth: initial validation of the Survey of Attitudes and Life Experiences

Psychopathic youth pose special challenges to clinicians in providing effective treatment and safe management. Because comprehensive assessments of psychopathy are time intensive and require specialized training, programmatic research is needed to develop time-efficient and useful screens that eliminate from further consideration acting-out adolescents who are unlikely to be psychopathic. The clinical utility of the Survey of Attitudes and Life Erperiences as a psychopathy screen was investigated by combining three samples of adolescent offenders (total N = 223). Its primary purpose was the identification of nonpsychopaths who were distinguished from adolescents in either the mixed or psychopathic ranges. A Psychopathy Screen (PS) Scale was developed with 24-item (PS-24) and 11-item (PS-11) versions. Both appeared moderately effective in excluding nonpsychopaths from further evaluation. Preliminary data on response styles suggest that these scales are not susceptible to social desirability.     

The Hannibal Lecter Myth: Psychopathy and Verbal Intelligence in the MacArthur Violence Risk Assessment Study

Due to the intriguing nature of the psychopathy construct, it is not surprising that psychopathic characters would appear in popular culture. At times, media portrayals of psychopathic personality are consistent with scholarly research, others times they are not. In the case of Hannibal Lecter, the psychopathic killer was framed as an individual with superior intelligence—an omnibus intelligence that enhanced his ability to manipulative and victimize others. Contrary to this popular conception and based on data from 840 cases selected from the MacArthur Violence Risk Assessment Study, ordinary least squares and ordered logistic regression models showed inverse relationships between verbal intelligence and psychopathy for eight of twelve items of the disorder in this exploratory study. Due to the uniqueness of the MacArthur sample and concern about generalizeability, further research on verbal intelligence and psychopathy is recommended.     

Exploring Associations Between Psychopathic Personality and Components of Disinhibition vs. Constraint

Recent models of psychopathy implicate Disinhibition vs. Constraint (DvC) as one of the primary underpinnings of psychopathic traits, although little research has examined associations between specific DvC components and psychopathy facets. The present study aimed to fill this gap by examining associations between psychopathy facets, as operationalized by two widely used self-report psychopathy instruments, and lower-order components of DvC within a racially diverse sample of 1,160 undergraduates. Path analyses confirmed the broad dimension of DvC as representing a general diathesis to psychopathy, with second-order components conferring more specific risks for particular psychopathy traits regardless of the model of psychopathy employed. Further, findings suggest that associations do not vary by race. Results suggest both generality and specificity of DvC dimensions as they relate to psychopathic traits, as well as potential avenues for further investigation of the associations between psychopathy and DvC.     

Attention Network Performance and Psychopathic Symptoms in Early Adolescence: An ERP Study

Reaction time (RT) and event-related potential (ERP) measures were used to examine the relationships between psychopathic symptoms and three major attention networks (alerting, orienting, and executive attention) among a community sample of youth. Antisocial Process Screening Device (APSD; Frick and Hare 2001) total and subscale scores were negatively correlated with ERP measures of attentional alerting, indicating that youth with psychopathic symptoms had difficulty using warning cues to prepare for upcoming targets. APSD total scores were not related to performance on measures of orienting or executive attention, although weaker executive attention was found among youth with higher scores on the Impulsivity subscale. These findings support attention-based models of psychopathy and provide evidence of specific deficits in attentional alerting among youth with psychopathic traits. Deficiencies in attentional alerting may be related to noradrenergic functioning and may have cascading effects on higher order cognitive and affective processing.     

Investigating the Components of Psychopathic Traits in Youth Offenders

Despite widespread acceptance of the importance of psychopathic traits in youth, the relative importance of different components of psychopathy remains controversial. This study was conducted to examine whether the interpersonal and lifestyle facets of psychopathy as measured with a valid clinical measure of psychopathic traits contribute to predicting relevant external criteria on top of the contributions of the affective facet. To address this issue, we conducted multiple regressions predicting antisocial behavior, exposure to violence, and psychopathology in a sample of 225 incarcerated adolescents. Results indicated that ratings on the affective component of psychopathy were important in helping to explain variance in many of the external criterion variables but that ratings on the interpersonal and lifestyle facets also helped to explain unique variance in a range of criteria including violent and non-violent crime, exposure to violence, impulsivity, and anger expression. These studies suggest that multiple components of psychopathy are likely to be important both in predicting real world outcomes and in understanding mechanisms involved in the development and manifestation of these traits.     

The reliability, stability, and predictive utility of the self-report version of the Antisocial Process Screening Device

The psychometric properties of the self-report version of the Antisocial Processes Screening Device (APSD; Frick & Hare, 2001), a rating scale developed to assess traits associated with the construct of psychopathy in youth, was tested in a sample of 91 non-referred young adolescents with an average age of 13.38 (SD = 1.75) at the initial assessment. The sample was recruited from a large community-wide screening, where youth with conduct problems and youth high on psychopathic traits were over-sampled. The sample was reassessed three times at yearly intervals. The self-report scores on the APSD showed moderate correlations with parent ratings of psychopathic traits, were moderately stable across 1-2 years, and showed significant correlations with measures of antisocial behavior both concurrently and predictively. One major weakness of the self-report ratings was the low internal consistency of the subscales, which were much lower than the internal consistency found on the parent report version of the scale.     

The 4 year stability of psychopathic traits in non-referred youth

One significant limitation in research extending the construct of psychopathy to youth has been the absence of longitudinal studies testing the stability of psychopathic traits prior to adulthood. To begin to address this limitation, the current study estimated the stability of psychopathic traits over a 4 year period in a sample of non-referred children in the third, fourth, sixth, and seventh grades at the first assessment. For parent ratings of psychopathic traits, stability estimates using intra-class correlation coefficients ranged from 0.80 to 0.88 across 2-4 years, with a stability estimate of 0.93 across all four assessments. There were also distinct trends in the patterns of stability found in the sample. Specifically, children rated as being initially high on these traits were more likely to be rated lower at later assessments than was the case for children rated initially low on these traits. Finally, the child's level of conduct problems, the socioeconomic status of the child's family, and the quality of parenting the child received were the most consistent predictors of stability of psychopathic traits.     

The relationship between psychopathic features, violence and treatment outcome: the comparison of three youth measures of psychopathic features

Few studies have compared self-report and clinician-administered measures of youth psychopathic features in juvenile-justice settings in terms of antisocial behavior and treatment indices. In a sample of 85 adjudicated delinquents, the predictive validities of the Antisocial Process Screening Device (APSD), the modified Childhood Psychopathy Scale (mCPS), and the Hare Psychopathy Checklist: Youth Version (PCL:YV) were tested. Three indices of institutional antisocial behavior (physical aggression; verbal aggression; administrative infractions) and two indices of treatment progress (time to treatment level promotion; whether treatment levels were dropped) were used as external correlates. The self-report measures (mCPS more so than APSD) were more consistently and strongly related to antisocial behavior and to the days required to progress in treatment than the PCL:YV. The following issues are discussed: (i) implications of the potential impact of measurement format on the understanding and predictive validity of youth psychopathy features and measures; (ii) the differential predictive validity of self-report versus clinician-administered measures; and (iii) the potential practical utility of measures of psychopathic features in youth.     

The Multidimensional Nature of Psychopathy: Five Recommendations for Research

The seven articles in this Special Section of the Journal of Psychopathology and Behavioral Assessment underscore the point that, at least in the psychopathy domain, parsimony is frequently an inaccurate scientific heuristic. These articles highlight the multidimensionality of youth psychopathy, suggesting that (a) the full constellation of psychopathy tends to outperform callous-unemotional traits alone in statistically predicting external criteria, (b) psychopathy subdimensions often interact statistically in predicting such criteria, and (c) psychopathy subdimensions often bear markedly different external correlates, including criminal offending, trait anxiety, and emotion processing. I offer five recommendations for future research on psychopathy and argue that that a full comprehension of this condition will require a better understanding of its subdimensions, and their interrelations, placement within the general personality domain, physiological correlates, and genetic and environmental underpinnings.     

Self-report measures of child and adolescent psychopathy as predictors of offending in four samples of justice-involved youth

The authors examined the relation between self-report psychopathy measures and official records of offending in four samples of justice-involved youth (total N = 447). Psychopathy measures included the Antisocial Process Screening Device (APSD) and a modified version of the Childhood Psychopathy Scale (mCPS). Measures of offending included the total number of preadmission arrest charges for three samples (n = 392) and the total number of offenses in the year following release for two samples (n = 138). Neither measure was a strong correlate of preadmission offenses. Although mCPS scores were associated with postrelease offending in one sample, effects for the APSD were observed only when reoffending was conceptualized as a dichotomous variable, indicating a lack of robustness in this association. The findings suggest caution in the use of self-report measures of psychopathic features for decision making with respect to issues of delinquency risk among justice-involved youth.     

Are Callous Unemotional (CU) Traits Enough?

A guiding question for this special section, sparked by the increasing number of studies on callous –unemotional traits (CU traits) and the DSM-5 Limited Prosocial Emotion (LPE) specifier, is whether CU traits are enough to identify a clinically meaningful subgroup of youth with conduct problems or whether other psychopathic traits contribute. Seven empirical papers and two commentary papers address this question to varying degrees and in different ways with some papers “competing” various models against one another along with other papers investigating distinct correlates of the psychopathy factors. Findings across the papers suggest that there could be benefits to examining the broader construct of psychopathy in addition to examining its underpinning dimensions rather than CU traits alone. Two commentary papers also shed light on the importance of psychopathic traits in children with Conduct Disorder (CD) and provide insights for future work on this topic. It is hoped that the articles and commentary will generate new ideas for research and practice that could have implications for the treatment of those individuals with CD and psychopathic traits.     

An Examination of Triarchic Psychopathy Constructs in Female Offenders

This study sought to expand scientific knowledge on psychopathic personality traits in female offenders by evaluating the relationship between MMPI–2–RF triarchic scales and self-reported external variables in a sample of 205 female offenders. Results indicated that boldness was inversely related to internalizing dysfunction, including suicidal behavior, psychosis, youth conduct problems, problems stemming from alcohol use, and a history of outpatient mental health treatment. Meanness was positively related to internalizing dysfunction as well as youth conduct problems, anger, prison disciplinary reports, and psychosis. Disinhibition was associated with a history of abuse in childhood, suicidal behavior, internalizing dysfunction, problems associated with alcohol and drug use, family history of mental illness, prison disciplinary reports for violence, number of previous criminal charges, and anger. Consistent with views of psychopathy as a configural condition, interactive effects of boldness with disinhibition and meanness were observed for multiple key external variables (e.g., conduct problems, substance use, nonsuicidal self-injurious behavior). This study provides further evidence for the triarchic conceptualization of psychopathy in female offenders and lends additional support for the validity of MMPI–2–RF triarchic psychopathy scales.     

Comparing Different Approaches for Subtyping Children with Conduct Problems: Callous-Unemotional Traits Only Versus the Multidimensional Psychopathy Construct

The aim of this study was to compare two youth psychopathy models (i.e., callous-unemotional versus multidimensional model) in their ability to predict future and stable conduct problems (CP). At baseline, mothers and fathers of 321 boys and 369 girls (ages 7–12) completed measures that tap callous-unemotional and other psychopathic traits. Parent-reported CP was collected at baseline and at 6- and 12 month follow-ups. Children were assigned to mutually exclusive groups based on their levels of CP and psychopathic traits. Children with CP who manifested callous-unemotional traits (Callous-Unemotional?+?CP) were occasionally at risk for future and stable CP. Yet, across gender, children with CP scoring high on all psychopathic trait dimensions (Psychopathic Personality?+?CP) showed the most robust and highest risk for future and stable CP. Also, Callous-Unemotional?+?CP children, and children who were only high in CP, often were at similar risk for future CP. The findings suggest that the callous-unemotional model is less sufficient than the multidimensional model in predicting future and stable CP. This can be concluded for both boys and girls and calls for more research reconsidering the multidimensional nature of psychopathy for CP subtyping purposes.     

Callous-Unemotional Traits Only Versus the Multidimensional Psychopathy Construct as Predictors of Various Antisocial Outcomes During Early Adolescence

The aim of this study was to compare callous-unemotional (CU) traits versus the multidimensional psychopathy construct in their ability to predict future and stable antisocial behavior. At baseline, a community sample of 996 Cypriot 12-year old adolescents (52% girls) completed measures that tap conduct problems (CP) and psychopathic traits, including CU. CP, aggression, and substance use were self-reported at 1–3 year follow-ups. Youths were assigned to six mutually exclusive groups based on their baseline levels of CP and psychopathic traits. Youth with CP scoring high on all three psychopathic traits dimensions (Psychopathic Personality?+?CP) showed the most robust and highest risk for future and stable CP, aggression, and substance use, followed by youth who were high on all three psychopathic traits dimensions but displayed no concurrent CP (Psychopathic Personality Only) and CP youth with low levels of psychopathic traits (CP Only). Youth with CP who merely manifested callous-unemotional traits (Callous-Unemotional?+?CP) were only at risk for future CP. The findings suggest that the CU traits-based approach for subtyping children with CP is less informative compared to a subtyping approach using various psychopathic traits dimensions in predicting future and stable forms of various antisocial outcomes. These findings and their consistency with prior work indicate the need for additional research to examine the various psychopathic traits dimensions rather than focusing solely on CU traits, especially for CP subtyping purposes.     

Selected Rorschach variables of psychopathic juvenile offenders

Despite the widely accepted utility of assessing psychopathic personality features in forensic and clinical settings, the Hare Psychopathy Checklist-Revised (PCL-R; Hare, 1991) stands virtually alone in its ability to do so with adequate reliability and validity. Recent studies have demonstrated the effectiveness of the Rorschach Inkblot Method in assessing psychopathy in adult samples, but almost no studies are currently available investigating the Rorschach's ability to assess the condition in younger samples of precisely defined psychopathic groups. In this study, 66 male juvenile offenders, ages 14 to 17, were placed into 3 groups according to level of psychopathy as measured by the youth version of the PCL-R (PCL:YV; Forth, 1995). Nine Rorschach variables conceptually related to various psychopathic features were investigated. Two of the variables (Reflections and Texture Responses) demonstrated statistically significant differences across groups (p < .05). Two additional variables (Vista and White Space) were produced in patterns consistent with existing research, although only to a weak degree. The remaining variables (Egocentricity Index, Form Dimension, Pure Human Content, Inanimate Movement, and Diffuse Shading) did not differ across groups in the predicted directions. Overall, these results offer some support for the validity of the Rorschach as a method of detecting certain psychopathic personality features, including pathological narcissism and interpersonal detachment, in adolescent male offenders.
