Psychopathy and violence in juvenile delinquents: What are the associated factors?

The purpose of the present study was a) to examine the discriminative power of the Antisocial Process Screening Device (APSD), aggressive traits, impulsiveness, antisocial attitudes and alcohol-related problems between subgroups of Russian juvenile delinquents (n = 175) with low versus high levels of violent behavior; and b) to compare the predictive value of these variables in two subgroups defined by higher versus lower levels of psychopathic traits. Results demonstrated that the APSD score, traits of physical aggression and alcohol-related problems were able to discriminate between groups with various levels of violence. Furthermore. the level of violence was the only variant factor when comparing levels of psychopathy. Finally, different sets of predictors emerged for the group with higher versus lower psychopathy scores. The results are discussed in relation to specific features of psychopathy and environmental factors in general and the use of alcohol in particular. (C) 2008 Elsevier Inc. All rights reserved.
