The role of psychopathic traits and developmental risk factors on offending trajectories from early adolescence to adulthood: A prospective study of incarcerated youth

PurposeCriminal career research has recently found that symptoms of psychopathy are more prevalent among offenders following chronic offending trajectories. In the current study, the ability of psychopathy to predict involvement in chronic offending trajectories above other criminogenic risk factors was examined. MethodsCriminal convictions were measured for Canadian male (n=262) and female (n=64) offenders at each year between ages 12 and 28. Semi-parametric group-based modeling identified four unique trajectories labeled bell-shape offenders (27.9% of sample), slow desisters (28.5%), slow rising chronic offenders (19.0%), and high rate chronic offenders (24.5%). ResultsThe four and three factor model of the PCL: YV were associated with the most chronic and serious offending trajectory even after controlling for a variety of relevant criminogenic risk factors. Self-reported involvement in weekly physical fights was a significant predictor of trajectory group membership, but most criminogenic risk factors were more informative of the strength of the relationship between higher symptoms of psychopathy and offending trajectories than of a direct effect of a specific risk factor on the unfolding of offending. ConclusionsInterpersonal and affective symptoms of psychopathy were not related to chronic offending. Future research should examine whether these symptoms are related specifically to involvement in violent offending.

The role of psychopathic traits and substance abuse in predicting violent victimization in patients with schizophrenia spectrum disorders

We examined the relationship between psychopathic traits and substance abuse and violent victimization in 94 community patients meeting DSM-IV criteria for schizophrenia spectrum disorders in contact with public mental health services in Victoria, Australia. Data on violence and victimization were collated from multiple sources and combined to categorize patients into victims of serious violence (VV; n = 74) and those who were not victims of serious violence (NVV; n = 20) groups. The VV group had higher rates of unemployment and previous violence but did not differ from the NVV on current symptom ratings. The VV group has significantly higher substance abuse and psychopathy scores, but only psychopathy score significantly contributed to the prediction of victimization. All psychopathy facets were reasonably good predictors of victimization status, but the antisocial facet contributed most to the prediction of victimization. A better understanding of the role and contribution of antisocial (particularly psychopathic) traits in violent victimization in mentally ill populations is needed to better inform community management plans.

Disentangling the Role of Psychopathic Traits and Externalizing Behaviour in Predicting Conduct Problems from Childhood to Adolescence

Child and youth conduct problems are known to be a heterogeneous category that implies different factors and processes. The current study aims to analyze whether the early manifestation of psychopathic traits designates a group of children with severe, pervasive and persistent conduct problems. To this end, cluster analysis was conducted in a sample of 138 children (27.6 % female), aged 6-11 at the first wave of the study (T1) and 12-17 in a follow-up carried out 6 years later (T2). Results allowed the identification of four distinctive clusters: Primarily externalizing, Externalizing-psychopathic, Primarily psychopathic and Non-problematic. As was expected, the Externalizing-psychopathic cluster showed the most severe and persistent pattern of behavioral, temperamental and social disruptions across the 6 years of the study. Early psychopathic traits seemed also to be relevant in predicting higher levels of conduct problems in T2, even when conduct disorders had not manifested in T1. These results highlight the role of psychopathic traits in predicting adolescent psychosocial disorders and the relevance to analyze them at early developmental stages.
