Psychopathic Personality Traits in Relation to Self-report Delinquency in Adolescence: Should We Mind About Interaction Effects?

The aim of the present study was to investigate if interaction effects among Youth Psychopathic Traits Inventory (YPI) Grandiose-Manipulative (GM), Callous-Unemotional (CU), and Impulsive-Irresponsible (II) may add significant information in predicting self-reports of juvenile delinquent behavior among adolescents. A sample of 558 Italian high school students were administered the YPI and the Self-Reports of Delinquency Scale (SRDS) in order to evaluate interaction effects among YPI GM, CU, and II dimensions. Results showed a significant effect for a three-way interaction among the three YPI dimensions in predicting the SRDS total score, β?=?.19, p?<?.01. In conclusion, the findings seem to underline that a three-factor model of psychopathy may help clinicians and researchers in predicting self-reported delinquency better than the individual factors.     

Psychopathy and recidivism from mid-adolescence to young adulthood: cumulating legal problems and limiting life opportunities

This study examined the ability of psychopathy as indexed by the following 4 scales: Psychopathy Checklist: Youth Version (A. E. Forth, D. S. Kosson, & R. D. Hare, 1996/2003), Antisocial Process Screening Device (P. J. Frick & R. D. Hare, 2001), Hare Self-Report Psychopathy Scale-II (R. D. Hare, 1991), and Personality Assessment Inventory-Antisocial Scale (L. C. Morey, 1991, 2007) to prospectively predict antisocial outcomes including general and violent recidivism across a 3- to 4-year time span. Results indicated that psychopathy was predictive of both general and violent recidivism from mid-adolescence to young adulthood even after accounting for 14 variables theoretically linked to offending. These findings add to the recent research showing stability in the psychopathy traits across time by also demonstrating that psychopathy in adolescents also has a real-world effect, including a cost to society with higher rates of offending in the community and a cost to youth with cumulating legal records that are likely to narrow their potential for prosocial growth in the community.     

Construct validity of psychopathy in a community sample: a nomological net approach.

The construct validity of psychopathy was examined within a sample of 326 male and female university students. The interpersonal circumplex served as a nomological net for the examination of convergences between psychopathy measures and convergent and discriminant validity with a measure of personality disorders was examined using a matrix approach. Measures included: (a) Antisocial scale of the Personality Assessment Inventory (Morey, 1991); (b) Self-Report Psychopathy scale (Hare, 1991); (c) Psychopathic Personality Inventory (Lilienfeld & Andrews, 1996); (d) Personality Diagnostic Questionnaire-4 (Hyler, 1994); and (e) Interpersonal Adjective Scales Revised-Big 5 (Trapnell & Wiggins, 1991). Results indicated (a) substantial convergence between psychopathy measures; (b) high convergent validity between psychopathy measures and antisocial personality disorder; and (c) high discriminant validity from other personality disorders. The prevalence of psychopathy within this non-forensic sample is also discussed.     

Psychopathy and Anxiety in Children and Adolescents: New Insights on Developmental Pathways to Offending

This study examined the relation between psychopathy and anxiety in 130 juvenile offenders. Adolescents were administered three psychopathy scales (PCL-YV, APSD, and SRP-II), a measure of psychopathology (APS), and subsequently followed prospectively in the community for three years in order to track recidivism. Three mediational models were tested to determine whether psychopathy mediates the relation between anxiety (trait anxiety, fearlessness, and trauma) and future offending. Findings indicated that psychopathy mediated the relation between two types of anxiety (trait anxiety and fearlessness) and recidivism when using the PCL-YV as an index for psychopathy. These influences were not supported when using self-report measures of psychopathy (APSD and SRP-II) and the meditational models did not apply to the anxiety subtype of trauma for any of the psychopathy measures. The PCL-YV mediational models provide new insights on the relation between psychopathy anxiety and offending. Specifically, pathways from fearlessness to psychopathy and later offending were in the expected direction. Surprisingly, higher levels of trait anxiety were linked with higher levels of psychopathy and subsequent offending. This developmental difference is in contrast with theory and the adult literature on this topic. The results from the current study suggest that both fear and anxiety may be important considerations in treatment planning for the reduction of adolescent offending.     

Convergent and discriminant validity of psychopathy factors assessed via self-report: a comparison of three instruments

Psychopathy has been conceptualized as a personality disorder with distinctive interpersonal-affective and behavioral deviance features. The authors examine correlates of the factors of the Psychopathic Personality Inventory (PPI), Self-Report Psychopathy-II (SRP-II) scale, and Antisocial Process Screening Device (APSD) to understand similarities and differences among the constructs embodied in these instruments. PPI Fearless Dominance and SRP-II Factor 1 were negatively related to most personality disorder symptoms and were both predicted by high Dominance and low Neuroticism. In addition, PPI Fearless Dominance correlated positively with antisocial personality features, although SRP-II Factor 1 did not. In contrast, PPI Impulsive Antisociality, SRP-II Factor 2, and both APSD factors correlated with antisocial personality features and symptoms of nearly all personality disorders, and were predicted by low Love. Results suggest ways in which the measurement of the constructs in each instrument may be improved.     

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.     

Psychopathic Traits in Adolescence: the Importance of Examining Components in Face Processing,Voice Processing,and Emotional Skill

This study examined relations among interpersonal, affective, and impulsive-irresponsible psychopathic traits, emotional capacities, and recidivism rates in 144 detained adolescents. Emotional skill was conceptualized using a range of constructs, including face and voice processing, emotional intelligence, and self-reported cognitive and affective empathy. In addition, the relation between these concepts and recidivism three years after the initial assessment was examined. Results indicated that interpersonal traits were positively associated with better facial identification of fearful faces, whereas affective traits were associated with worse facial identification of sad and happy faces as well as angry voices. Impulsive-irresponsible traits were associated with reduced emotional intelligence. Differential predictive utility of the three psychopathic traits dimensions was also evidenced. Findings highlight the need to consider the broad concept of psychopathy, but also its underlying dimensions.     

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.
