BACKGROUND: The incidence of the aggressive behavior is higher among the patients with severe mental disorder such as schizophrenia than the general population. The study of factors related to aggressive behavior has great meaning in designing prevention and intervention methods with this population of patients. AIMS: To understand the characteristics of assaultive behavior of male patients with schizophrenia who have been hospitalized. METHODS: Using a continuous sampling method, data from 75 male inpatients with a diagnosis of schizophrenia was collected at the psychiatric unit of Central South University Second Xiangya Hospital (Changsha, China) from August 2015 to February 2016...

It is not known how mortality differs between psychopathic and nonpsychopathic individuals. We linked data from subjects having been in forensic mental examinations at Niuvanniemi Hospital during 1984-1993 to the data from the National Death Registry to estimate the association between psychopathy and mortality. One hundred psychopathic individuals scoring 25 or higher in the PCL-R scale were followed up for 20-30 years. Two control groups were used as follows: 178 offenders scoring less than 25 on the PCL-R, and sample of general population drawn from the Finnish National Statistics database...

The presence of callous-unemotional (CU) traits delineates a subgroup of male youth with severe conduct disorder and antisocial behavior, but little research has been done among female youth. Drawing on 377 female adolescents (103 selected from forensic settings and 274 selected from school settings) from Portugal, the current study is the first to simultaneously examine the psychometric properties of the Inventory of Callous-Unemotional Traits (ICU) in incarcerated female youth and community youth. The results support the use of the ICU in terms of its factor structure, and internal consistency despite the fact an item had to be removed from the Callousness dimension...

The current study employed both latent variable- and person-centered approaches to examine psychopathic traits in a large sample of sex offenders (N = 958). The offenders, who had committed a range of sexual crimes, had been assessed with the Psychopathy Checklist-Revised (PCL-R; Hare, 2003). Structural equation modeling results indicated that the four-factor model of psychopathy (Hare, 2003; Neumann, Hare, & Newman, 2007) provided good representation of the dimensional nature of psychopathic traits across the sample of offenders, and that the PCL-R factors significantly predicted sexual crimes...

In 2009, Gao and Raine's meta-analysis analysed P3 modulation over the antisocial spectrum. However, some questions remained open regarding the P3 modulation patterns across impulsive and violent manifestations of antisocial behaviour, phenotypic components of psychopathy, and P3 components. A systematic review of 36 studies was conducted (N=3514) to extend previous results and to address these unresolved questions. A clear link between decreased P3 amplitude and antisocial behaviour was found. In psychopathy, dimensional approaches become more informative than taxonomic models...

Psychopathic traits are a manifestation of a personality pathology that comprises a core affective-interpersonal dysfunction (callous-unemotional traits) and an impulsive-antisocial behavioral component. Of particular importance, psychopathic traits are associated with the perpetration of some of the most severe acts of violence, and they appear to indicate a subset of youth at risk for earlier onset, greater frequency, and persistence of violent offending. Although these youth represent a minority of the population, they commit a significant proportion of the violence in the general community...

The purpose of this study is to analyse individual differences in the ability of emotional facial recognition in violent offenders, who were characterised as either reactive or proactive in relation to their offending. In accordance with findings of our previous study, we expected higher impairments in facial recognition in reactive than proactive violent offenders. To assess the ability to recognize facial expressions, the computer-based Facial Emotional Expression Labeling Test (FEEL) was performed. Group allocation of reactive und proactive violent offenders and assessment of psychopathic traits were performed by an independent forensic expert using rating scales (PROREA, PCL-SV)...

The present study aimed to examine whether callous-unemotional, grandiose-manipulative, and impulsive-irresponsible dimensions of psychopathy are differentially related to various affective and physiological measures, assessed at baseline and in response to violent and erotic movie scenes. Data were collected from young adults (N = 101) at differential risk for psychopathic traits. Findings from regression analyses revealed a unique predictive contribution of grandiose-manipulative traits in particular to higher ratings of positive valence for violent scenes...

BACKGROUND: Antisocial personality and psychopathic traits have constantly been found to accompany criminal and aggressive behaviors, but little attention has been given to aspects of character maturity and its relation to such behaviors. The present study investigated (1) whether level of character maturity (low, medium, and high) is associated with amount of aggressive antisocial behaviors (AABs) and psychopathic traits in young men imprisoned for violent criminality, and (2) whether such an association is independent of coexisting attention-deficit hyperactivity disorder (ADHD)...

BACKGROUND: Psychopathy is a specific syndrome that predicts future violent and aggressive behavior in adults. Studies in youth and adults have demonstrated a strong association between early traumatic incidents and later dissocial behavior. Moreover, the impact of personality pathology and emotional dysregulation on aggressive and violent behavior is well established. However, few studies have addressed the relationship between early traumatization and psychopathic traits in adolescents...

BACKGROUND: More research is needed to improve our understanding of the manifestation of psychopathic traits in violently offending girls. Our aim here was to assess psychopathic traits and psychopathy-related background variables in a Finnish nationwide consecutive sample of girls charged with violent crimes and referred to a pretrial forensic psychiatric examination. These girls were then compared to their male counterparts. METHODS: The forensic psychiatric examination statements of 15- to 17-year-old juveniles who underwent a pretrial forensic psychiatric examination over a 31-year period (1980-2010) were reviewed...

We examined different forms of victimization experiences in relation to psychopathic features and whether these associations differed in boys and girls among 4855 Finnish school adolescents aged 15-16 years. Psychopathic features were measured with the Antisocial Process Screening Device- Self Report (APSD-SR). Victimization was assessed with questions about violent and abusive experiences across lifetime and within the last 12 months. Results from linear regression analysis showed that victimization was significantly associated with higher APSD-SR total scores, more strongly in girls than boys...

REVIEW
Edelyn Verona
Researchers have long acknowledged heterogeneity among persons who exhibit antisocial and violent behaviours. The study of psychopathic personality or psychopathy can help elucidate this heterogeneity through examination of the different facets that constitute this disorder. In particular, the distinct correlates of the interpersonal-affective traits (Factor 1) and the impulsive-antisocial traits (Factor 2) of psychopathy suggest at least two possible pathways to antisocial behaviours. Building on basic studies in cognitive and affective neuroscience, we provide a focused, non-comprehensive review of work identifying the biopsychological mechanisms involved in these two pathways, with special attention to studies using event-related potential (ERP) methods...

The cognitive view on deception holds that lying typically requires additional mental effort as compared to truth telling. Psychopathy, however, has been associated with swift and even compulsive lying, leading us to explore the ease and compulsive nature of lying in psychopathic offenders. We explored the costs of instructed lying versus truth telling through RTs and error rates in 52 violent male offenders, who were assessed with the Youth Psychopathic Traits Inventory (YPI). Our deception paradigm also included trials with the free choice to lie or tell the truth...

Instrumental or goal-directed aggression is a core feature in violent offenders with psychopathic tendencies. To understand this type of behavior, previous work in the field of aggression has focused on affective processing, with mixed results. We propose that instrumental aggression is best understood in terms of the consequences of affective processing for instrumental behavior rather than affective processing per se. Therefore, we assessed the degree of affective biasing of instrumental action in a group of violent offenders with psychopathic tendencies and healthy controls using a validated affective decision-making task...

This study examined associations of psychopathy facets of boldness, meanness, and disinhibition with clinically relevant variables and physiological reactivity to affective stimuli. These associations were examined after accounting for developmental associations with adolescent psychopathic traits, namely callous-unemotional traits, narcissism, and impulsivity. Psychopathic traits were assessed during adolescence using the Antisocial Process Screening Device and the Inventory of Callous Unemotional traits and during young adulthood via the Triarchic Psychopathy Measure...

This study investigated positive and negative reactions and conciliatory behaviors after perpetration of intimate partner violence (IPV). The goals were to examine the rates of these reactions and their associations with key attitudinal and personality factors. During program intake at a community agency, 172 partner violent men completed assessments of positive reactions (e.g., feeling justified) and negative reactions (e.g., feeling ashamed) after IPV, conciliatory behaviors after IPV (e.g., buying flowers for the partner), frequency of physical assault and abuse perpetration, and motivational readiness to change...

The present study investigated the relations between morally disengaged attitudes, psychopathic affective traits, and a variety of antisocial and risky behaviors in a sample of adults (N=181). A second aim of the study was to examine the unique contributions of moral disengagement and psychopathic traits in predicting problematic behavior while the other construct is statistically controlled. Results indicated that whereas psychopathic traits and moral disengagement were both uniquely predictive of non-violent antisocial behaviors, only remorselessness was uniquely predictive of violence and only morally disengaged attitudes were uniquely predictive of academic cheating...

The authors provide a comprehensive review of the neurobiology of empathy and compare this with the neurobiology of psychopathic predatory violence-the most extreme deficit of empathy. This suggests that the specific areas of the prefrontal cortex and limbic system, which have been associated with violent behavior, also appear to subserve the capacity for empathy. Damage to these regions may result in the emergence of aggression, but not of empathy, suggesting a structurally inverse relationship between the two...

Callous-unemotional (CU) traits, that is, a lack of guilt or empathy and poverty of emotion, are believed to be the developmental precursor to psychopathy in adulthood, capturing its emotional detachment dimension. Similar to psychopathic adults, research shows that children and adolescents with high CU traits represent an important population at heightened risk for criminal behavior. The present study is the first to examine whether a self-report measure of CU traits, the Inventory of Callous-Unemotional Traits (ICU), predicts general and violent recidivism postinstitutional release among a sample of 227 juvenile justice-involved adolescent boys (M age = 15...
