“…Schizoid PD is related as well with features of psychopathy and Antisocial personality according to Kosson et al [ 34 ]. Loza and Hanna argue that an association exists between Schizoid PD and violent acts [ 35 ]. This study found a significant relation only of “Cluster A” disorders with violent offenses.…”

BackgroundPersonality disorders (PDs) have been associated with both violent crimes and homicides in many studies. The proportion of PDs among prisoners reaches up to 80%. For male prisoners, the most common PD in the literature is antisocial PD. The aim of this study was to investigate the association between PDs and violent crimes/homicides of male prisoners in Greece.MethodsA sample of 308 subjects was randomly selected from a population of 1300 male prisoners incarcerated in two Greek prisons, one urban and one rural. The presence of PDs was assessed using the Mini International Neuropsychiatric Interview (MINI) and the Personality Diagnostic Questionnaire-4 (PDQ-4). Using logistic regression models PD types and PD “Clusters” (independent variables) were associated with “violent/non-violent crimes” and “homicides/non homicides” (dependent variables).Results“Cluster A” PDs (Paranoid, Schizoid, and Schizotypal) were diagnosed in 16.2%, “Cluster B” (Antisocial, Borderline, Histrionic, Narcissistic) in 66.9% and “Cluster C” (Obsessive–Compulsive, Dependent, Avoidant) in 2.9% of the studied population. Violent crimes and homicides were found significantly associated with “Cluster A” PDs (p = 0.022, p = 0.020). The odds ratio of committing violent crimes was 2.86 times higher for patients with “Cluster A” PDs than the ones without PDs. In addition, the odds ratio of committing homicides was 4.25 times higher for patients with “Cluster A” PDs. In separate analyses, the commitment of violent crimes as well as homicides, was significantly associated with Schizoid (p = 0.043, p = 0.020) and Schizotypal PD (p = 0.017, p = 0.030).ConclusionsThe majority of prisoners was found to suffer from a PD, mainly the Antisocial “Cluster B”, but the commitment of violent crimes and homicides was significantly associated only with “Cluster A” PDs and specifically with Schizoid and Schizotypal PD.

“…Les résultats similaires obtenus dans ces divers milieux ont permis de confirmer que la relation entre ces troubles de personnalité et les comportements violents est présente dans ces diverses populations (Berman et al, 1998 ;Blonigen et Krueger, 2007 ;Fountoulakis et al, 2008 ;Loza, 2003 ;Loza et Hanna, 2006 ;Tardiff, 2001 ;Widiger et Trull, 1994). D'autres études ont permis de constater que des facteurs comme la consommation de substances psychoactives, les abus dans l'enfance, le fait d'avoir évolué dans un milieu criminel en bas âge peuvent solidifier le lien entre les comportements violents et les troubles de personnalité (Fountoulakis et al, 2008 ;Friedmann et al, 2008 ;Goethals et al, 2008).…”

Dans cet article, les auteures présentent une synthèse des écrits qui mettent en lumière le lien entre les troubles de la personnalité, les troubles de l’attachement et les comportements violents. Il a été établi que les troubles de personnalité et les troubles de l’attachement favoriseraient le passage à l’acte violent en contexte conjugal. Les auteures soulignent l’importance d’améliorer les connaissances sur cette relation afin d’adapter l’intervention auprès de la clientèle violente aux prises avec une problématique au niveau de la personnalité ou du lien d’attachement.Past research has established that personality disorders and attachment disorders are important risk factors for the perpetration of violent acts in a context of an intimate relationship. Very few studies have been conducted linking personality and attachment disorders to violent behaviors outside of the domestic violence context. This paper proposes to address this gap by reviewing the literature and linking these important concepts to general violence. This will allow a better understanding of the dynamics of violence and possibly open the door to new research and interventions taking into account both attachment and personality disorders as prodromic factors.En este artículo los autores presentan una síntesis de los textos que resaltan la relación entre los trastornos de la personalidad, los trastornos del apego y los comportamientos violentos. Se estableció que los trastornos de la personalidad y los del apego favorecen el paso a la violencia en un contexto conyugal. Los autores recalcan la importancia de mejorar los conocimientos acerca de esta relación a fin de adaptar la intervención a una clientela violenta presa de una problemática a nivel de la personalidad o de la relación de apego.Neste artigo, as autoras apresentam uma síntese da literatura que ressalta a relação entre os transtornos de personalidade, os transtornos de apego e os comportamentos violentos. Foi estabelecido que os transtornos de personalidade e os transtornos de apego favoreceriam a passagem ao ato de violência em contexto conjugal. As autoras ressaltam a importância de melhorar os conhecimentos sobre esta relação a fim de adaptar a intervenção junto à clientela violenta que sofre de uma problemática de personalidade ou de apego
