Psychopathy and comorbidity in a young offender sample: taking a closer look at psychopathy's potential importance over disruptive behavior disorders

The authors examined the construct of psychopathy as applied to 130 adolescent offenders using 3 psychopathy measures and a broad range of DSM-TV Axis I diagnoses and psychosocial problems. Measures used in the study included the following: (a) Psychopathy Checklist-Youth Version, (b) Antisocial Process Screening Device, (c) a modified version of the Self-Report Psychopathy-II scale, and (d) the Adolescent Psychopathology Scale. Results from this study offer incremental support for the construct validity of psychopathy in youth. Psychopathy evidenced better convergent and discriminant validity results than did the disruptive behavior disorders (DBDs) such as oppositional-defiant disorder (ODD) and conduct disorder (CD). Despite this finding, psychopathy scales nonetheless correlated with other forms of psychopathology at a higher rate than was expected, suggesting that comorbidity is high even when psychopathy is used as a classification scheme. Also, hierarchical multiple regression was used to determine whether psychopathy offered an improvement in the prediction of previous violent and nonviolent offenses. The results for the current study were mixed, with only the PCL-YV significantly predicting previous violent and nonviolent offenses beyond the DBDs. The findings indicate that psychopathy may offer incremental improvement over DBDs with regard to level of comorbidity and perhaps even prediction. However, simply extending the adult construct of psychopathy to youth without considering the array of psychopathology that may accompany adolescent psychopathy could be misleading.     

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.     

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.     

Psychopathy in adolescent female offenders: an item response theory analysis of the psychopathy checklist: youth version

The present study examined the applicability of the PCL:YV items to a sample of detained adolescent girls. Item response theory (IRT) was used to analyze test and item functioning of the PCL:YV. Examination of IRT trace lines indicated that the items most discriminating of the underlying construct of psychopathy included "callousness and a lack of empathy", "conning and manipulation", and "a grandiose sense of self-worth". Results from the analyses also demonstrated that the items least discriminating in this sample, or least useful for identifying psychopathy, included "poor anger control", "shallow affect", or engaging in a "serious violation of conditional release". Consistent with previous research (Cooke & Michie, 1997; Hare, 2003), interpersonal and affective components of psychopathy provided more information than behavioral features. Moreover, although previous research has also found affective features to provide the most information in past studies, it was interpersonal features of psychopathy in this case, followed by affective features, that provided greater levels of information. Implications of these results are discussed.     

Adolescent Psychopathy and the Five Factor Model: Domain and Facet Analysis

Given the consideration of callousness as a specifier for Conduct Disorder in the DSM-V, it seems imperative that researchers continue to investigate this personality style in adolescents to determine both its applicability and utility. The present study examined the Youth Psychopathic traits Inventory (YPI; Andershed et al. 2002) and the Interpersonal Adjective Scale Revised-Big 5 (IASR-B5; Trapnell and Wiggins 1990a, b) psychopathy scales in relation to the Five Factor Model (FFM) of personality. Using a sample of adolescent offenders (N = 145), the YPI and IASR-B5 psychopathy scales showed adequate reliability and strong inverse bivariate relations with the FFM domains of Agreeableness (−A) and Conscientiousness (−C). Multivariate analyses, at the facet level, revealed that Tendermindedness (−A) and Assertiveness (+E) explained the association between FFM facets and the YPI, whereas Altruism (−A), Modesty (−A), Straightforwardness (−A), Assertiveness (+E), Warmth (−E), and Deliberation (+C) all uniquely contributed to the IASR-B5 psychopathy scale. Both measures were linked with general and violent recidivism. The authors discuss the implications of these findings in terms of the use of personality to help describe conduct problem youth and the need for future research in this important area.
