Trait Anger, Physical Aggression, and Violent Offending in Antisocial and Borderline Personality Disorders

Childhood maltreatment and subsequent offending behaviors in Australian women: Exploring the role of borderline personality disorder

BACKGROUND

Childhood Maltreatment (CM) is linked to adverse outcomes, including Borderline Personality Disorder (BPD) and increased propensity for offending behaviors. However, research on the specific role that BPD plays between the two is limited and highly relevant given the high prevalence of CM in Australia.

OBJECTIVE

The present study aimed to investigate (1) the relationship between CM and subsequent offending behaviors, (2) whether BPD mediates the relation between CM and offending behaviors, and (3) which type of CM (physical, sexual, emotional abuse, neglect, exposure to domestic violence, multitype maltreatment) predicts BPD.

PARTICIPANTS

The sample comprised 106 self-identified Australian female survivors of interpersonal violent crimes.

METHODS

Participants completed an online survey consisting of the Adverse Childhood Events Questionnaire, the McLean Screening Instrument for BPD, and a self-created questionnaire to measure offending behaviors. Regression, mediation analysis, and logistic regression were conducted.

RESULTS

CM significantly predicted offending behaviors (path c, B = 1.39, p <. 001) with BPD partially mediating the relationship (path c', B = 1.04, 95 % CI [0.31, 1.77], p = .006; path a, B = 0.47, 95 % CI [0.12, 0.83], p = .009, path b, B = 0.34, 95 % CI [0.07, 0.61], p = .014). Emotional abuse and multitype exposure were identified as predictors of BPD symptom development (OR = 9.42, 95 % CI OR [2.58, 34.40]; OR = 3.81, 95 % CI OR [1.41; 10.28], respectively).

CONCLUSION

These findings indicate the necessity of early interventions addressing CM, with a particular focus on emotional abuse and exposure to more than one type of maltreatment, to reduce the risk of developing BPD symptomatology and mitigate future offending behaviors.

The relationship between trait anger and reactive aggressive behavior in middle school students: the mediating role and intervention of hostile attribution bias

BACKGROUND

The reactive aggressive behavior in individuals typically shows a rapid growth trend as individuals enter adolescence, and peaks during middle-school period. According to the Comprehensive Cognitive Model of Trait Anger, trait anger and hostile attribution bias play important roles in the development of reactive aggressive behavior. Based on this, current study explored the relationship between trait anger and reactive aggressive behavior in middle school students, as well as the mediating role of hostile attribution bias and interventions.

METHODS

The current study consisted of three sub-studies. Study 1 recruited 87 middle school students with an average age of 12.367 ± 0.889 years, investigated the relationship between trait anger and reactive aggressive behavior, as well as the mediating role of trait hostile attribution bias. Study 2 recruited 62 middle school students with an average age of 13.376 ± 0.963 years, investigated the relationship between trait anger and reactive aggressive behavior, as well as the mediating role of state hostile attribution bias. Study 3 recruited 80 middle school students with an average age of 13.392 ± 0.977 years, implemented an intervention targeting trait hostile attribution bias in middle school students with high trait anger to reduce their reactive aggressive behavior. In current study, data management was performed using SPSS 22.0. Descriptive statistics, independent samples t-test, paired samples t-test, repeated measures analysis of variance (ANOVA), and path analysis were used for statistical analysis.

FINDINGS

The results of Study 1 showed that trait anger predicted reactive aggressive behavior through trait hostile attribution bias. The results of Study 2 indicated that trait and state hostile attribution bias played mediating role intermediary, and trait hostile attribution bias had a stronger mediating effect than state hostile attribution bias. The results of Study 3 suggested that the intervention effectively decreased trait hostile attribution bias and reactive aggressive behavior.

CONCLUSIONS

Trait anger can predict the reactive aggressive behavior of junior high school students, with trait hostility attribution bias and state hostility attribution bias mediating this relationship. Intervening in the hostility attribution bias of high-anger junior high school students can effectively reduce their reactive aggressive behavior.

The validity of the Violence Risk Scale (VRS) in a Portuguese sample of remand prisoners

This study aims to test the psychometric properties of the Violent Risk Scale (VRS) in a sample of Portuguese remand prisoners. A total of 133 subjects participated in the present study. We carried out a Confirmatory Factor Analysis (CFA) to test the originally proposed two factor structure. Results showed evidence to support the VRS's psychometric qualities. The CFA tested the two-factor structure and showed evidence of the goodness of fit of the original two-factor model. Also, our findings indicated acceptable internal consistency for both subscales. The correlational analyses supported both convergent and discriminant validity of the VRS. Finally, this study also tested known-groups validity. The VRS score showed a satisfactory postdictive accuracy, which means that it is able to demonstrate distinctive scores for groups known to vary on the variables being measured. We consider this work represents an essential support for decision-makers to evaluate the appropriateness of different judicial measures.

Neural correlates of aggression in personality disorders from the perspective of DSM-5 maladaptive traits: a systematic review

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published in 2013, includes an alternative model of personality disorders (AMPD) focusing on a maladaptive trait model utilized to diagnose several personality disorders. Borderline personality disorder (BPD) and antisocial personality disorder (ASPD) are two conditions categorized by AMPD that exhibit high rates of violence and aggression. Several of the traits outlined in the AMPD, including hostility, impulsivity, risk-taking, and callousness, have been previously linked to aggression in BPD and ASPD. However, to the best of our knowledge, there has never been a synthesis of neuroimaging studies that have investigated links between these traits and aggression in BPD and ASPD. To overcome this gap, we conducted a systematic review under the PRISMA framework to locate neuroimaging articles published since the release of AMPD linking trait anger/hostility, impulsivity, risk-taking, and callousness to aggression in BPD and ASPD. Key findings included the following: i) anger/hostility, associated with alterations in the interplay between prefrontal and subcortical regions (primarily the amygdala), may be a common factor explaining aggressive reactions to response to interpersonal threat or provocation; ii) alterations of fronto-temporal-limbic regions and serotonergic and endocannabinoid signaling systems may link impulsivity to aggression in BPD and ASPD; iii) weaker cortico-striatal connectivity could relate to greater risk taking and greater proclivity for violence. Insufficient evidence from neuroimaging articles was discerned to describe a relationship between callousness and aggression. Overall, results of this review reveal a relative paucity of neuroimaging studies examining AMPD traits relevant to aggression in BPD and ASPD. In addition to encouraging further investigation of neuroimaging markers of AMPD traits linked to aggression, we recommend multi-methodological designs, including the incorporation of other biomarkers, such as hormones and indices of physiological arousal, to fully expand our understanding of aggression in BPD and ASPD.

Personality disorder and mild traumatic brain injury

Mild traumatic brain injury (mTBI) poses risk to the neurocognitive, emotional, and financial well-being of affected individuals. While aggression and impulsivity have been examined in relation to mTBI, little work has been done to evaluate the relationship between history of mTBI and personality disorder (PD). The authors examined the associations between history of mTBI and PD in a control group without history of mTBI (N = 1189) and individuals with history of mTBI (N = 267). Results demonstrated that any PD diagnosis is a significant risk factor for mTBI (p < 0.001). Cluster B diagnoses, particularly borderline and antisocial PD, were independently significant risk factors for mTBI. These data suggest a role for screening for a history of mTBI in patients with PDs and associated traits.

Impulsive Lifestyle Counselling versus treatment as usual to reduce offending in people with co-occurring antisocial personality disorder and substance use disorder: a post hoc analysis

OBJECTIVES

To assess the impact of a short psychoeducation intervention for antisocial personality disorder on offending after randomization to treatment.

DESIGN

Multicentre, superiority, non-blinded randomized controlled trial. Random assignment was conducted in blocks of varying sizes at a central randomization centre. Participants were followed using national register data until 365 days after randomization, migration, or death, whichever occurred first.

SETTING

Thirteen outpatient uptake areas in Denmark.

PARTICIPANTS

Patients with antisocial personality disorder in treatment for substance use disorders were randomized to treatment as usual (TAU, n = 80) or Impulsive Lifestyle Counselling (ILC, n = 96). A total of 165 patients could be linked to criminal records (TAU, n = 74; ILC, n = 91).

INTERVENTION

ILC is a brief psychoeducational program targeting antisocial behavior. The trial was conducted between January 2012 and June 2014.

OUTCOMES

Number of criminal offences leading to convictions based on national registers.

RESULTS

The mean number of offences was 2.76 in the TAU group (95% Poisson confidence interval [CI] = 2.39, 3.16) and 1.87 in the ILC group (95% CI = 0.97, 1.43). Negative binomial regression was used to assess total number of convictions, as well as convictions for violent, property, driving under the influence, and drug-related crimes. In both adjusted and unadjusted analyses, random assignment to ILC was associated with a lower number of total offences (incidence rate risk ratio [IRR] = 0.43, p = .013; adjusted IRR = 0.45, p < .001) and convictions related to violence (IRR = 0.19, p = .001 adjusted IRR = 0.19, p = .007) and property offences (unadjusted IRR = 0.30, p = 0.003, adjusted IRR = 0.42, p = 0.010). Differences between conditions were not significant for driving under the influence (unadjusted IRR = 0.49, p = .370; adjusted IRR = 0.53, p = .417) or drug offences (unadjusted IRR = 1.06, p = .907; adjusted IRR = 0.55, p = .223).

CONCLUSIONS

The ILC program shows promise in reducing offending behavior in people with comorbid substance use and antisocial personality disorder.

Mental illness and HIV amongst female inmates in Durban, South Africa

BACKGROUND

There is limited data regarding the prevalence of mental illness and human immunodeficiency virus (HIV) amongst female inmates in South Africa. Rehabilitation programmes can only be formulated once the needs of this population have been identified.

AIM

This study aimed to measure the prevalence of mental illnesses, borderline and antisocial personality disorders and HIV amongst female inmates.

SETTING

The study was based at a correctional centre in Durban, KwaZulu-Natal, South Africa.

METHODS

This study forms part of a larger two-phased, mixed methods, sequential, explanatory design study. In phase one, 126 female inmates were interviewed using a clinical questionnaire and the Structured Clinical Interview for Diagnostics and Statistical Manual (DSM)-5 diagnoses - Research Version.

RESULTS

The following lifetime prevalence rates were found: depressive disorder 70.6%, alcohol use disorder 48.4%, post-traumatic stress disorder (PTSD) 46.8%, borderline personality disorder 33.3%, substance use disorder 31.7%, antisocial personality disorder 15.1% and psychotic disorder 4.8%. The prevalence of current adult attention-deficit and hyperactivity disorder was 9.5%. A total of 39% of the participants admitted to past suicide attempts, whilst 64.3% reported past suicidal ideation and 36.5% had a current episode of a psychiatric disorder. A total of 64.3% of the participants were living with HIV. Although 90.4% had a lifetime psychiatric disorder, only 16.7% were previously diagnosed with a mental illness. The majority of inmates with lifetime disorders had psychiatric comorbidities.

CONCLUSION

The high prevalence of mental illness and HIV amongst female inmates, and the fact that most with mental illness remain undiagnosed, is concerning. Improved screening, identification and treatment of mental illnesses in this population is needed to ensure optimal mental health outcomes and decreased recidivism.

Structural and functional brain networks of individual differences in trait anger and anger control: An unsupervised machine learning study

The ability to experience, use and eventually control anger is crucial to maintain well-being and build healthy relationships. Despite its relevance, the neural mechanisms behind individual differences in experiencing and controlling anger are poorly understood. To elucidate these points, we employed an unsupervised machine learning approach based on independent component analysis to test the hypothesis that specific functional and structural networks are associated with individual differences in trait anger and anger control. Structural and functional resting state images of 71 subjects as well as their scores from the State-Trait Anger Expression Inventory entered the analyses. At a structural level, the concentration of grey matter in a network including ventromedial temporal areas, posterior cingulate, fusiform gyrus and cerebellum was associated with trait anger. The higher the concentration, the higher the proneness to experience anger in daily life due to the greater tendency to orient attention towards aversive events and interpret them with higher hostility. At a functional level, the activity of the default mode network (DMN) was associated with anger control. The higher the DMN temporal frequency, the stronger the exerted control over anger, thus extending previous evidence on the role of the DMN in regulating cognitive and emotional functions in the domain of anger. Taken together, these results show, for the first time, two specialized brain networks for encoding individual differences in trait anger and anger control.

Anger and cluster B personality traits and the conversion from unipolar depression to bipolar disorder

INTRODUCTION

Feelings of anger and irritability are prominent symptoms of bipolar disorder (BD) that may occur during hypomanic, depressive and, especially, during mixed mood states. We aimed to determine whether such constructs are associated with the conversion to BD in subjects with a history of unipolar depression.

METHODS

Data were derived from the depressed participants of Netherlands Study of Depression and Anxiety with 9 years of follow-up. Hypomania was ascertained using the Composite International Diagnostic Interview at 2, 4, 6, and 9 years follow-up. Cross-sectionally, we studied the association between prevalent hypomania and anger related constructs with the "Spielberger Trait Anger subscale," the "Anger Attacks" questionnaire, the cluster B personality traits part of the "Personality Disorder Questionnaire," and "aggression reactivity." Prospectively, we studied whether aggression reactivity predicted incident hypomania using Cox regression analyses.

RESULTS

Cross-sectionally, the bipolar conversion group (n = 77) had significantly higher scores of trait anger and aggression reactivity, as well as a higher prevalence on "anger attacks," "antisocial traits," and "borderline traits" compared to current (n = 349) as well as remitted (n = 1159) depressive patients. In prospective analyses in 1744 participants, aggression reactivity predicted incident hypomania (n = 28), with a multivariate-adjusted hazard ratio of 1.4 (95% confidence interval: 1.02-1.93; p = .037).

CONCLUSION

Anger is a risk factor for conversion from unipolar depression to BD. In addition, patients who converted to BD showed on average more anger, agitation and irritability than people with a history of unipolar depression who had not converted.

Unraveling the Personality Profile of the Sexual Murderer

Although sexual homicide offenders (SHOs) evince personality disorders, few prior studies have examined all personality disorders or utilized control groups of offenders. Drawing on data from 616 adult male sex offenders including 85 who were SHOs, the current study examined the personality profile of the SHOs, by comparing them with a group of violent nonhomicidal sex offenders (VNHSOs) and a group of nonhomicidal sex offenders (NHSOs) on clinical diagnostics of personality disorders and various crime characteristics. The personality profile of SHOs is comprised primarily of Schizoid and Borderline Personality Disorders, and these offenders were significantly likely to select a victim, use a weapon, and use drugs and alcohol before their offenses, but less likely to force their victim to engage in sexual acts or humiliate them. The comorbidity of Schizoid, Borderline, and Antisocial Personality Disorder features presents unique personality dysfunction that facilitates the lethal sexual violence of SHOs relative to their nonhomicidal sexual offender peers.

DSM-5 Alternative Model of Personality Disorder Dysfunctional Personality Traits as Predictors of Self-Reported Aggression in an Italian Sample of Consecutively Admitted, Personality-Disordered Psychotherapy Patients

In order to assess the relationships between DSM-5 Alternative Model of Personality Disorder (AMPD) maladaptive personality traits and self-reports of aggression, 508 Italian adult participants who met at least one DSM-IV Axis II/DSM-5 Section II personality disorder (PD) diagnosis were administered the Personality Inventory for DSM-5 (PID-5) and the Aggression Questionnaire (AQ). Analysis results showed that multiple regression results, PID-5 Hostility, Callousness, and Risk Taking trait scale scores explained a large amount of variance in AQ Physical Aggression (PA) scores. Moreover, PID-5 Hostility, Callousness, and Risk Taking explained more than 20% of the variance in the AQ Physical Aggression scale scores that was left unexplained by selected continuously scored DSM-IV Axis II/DSM-5 Section II PDs, whereas SCID-II Paranoid, Narcissistic, Borderline, and Antisocial PDs added only 4% of variance to the amount of variance in AQ Physical Aggression scores that was already explained by the PID-5 trait scale scores.

Elevated fatty acid amide hydrolase in the prefrontal cortex of borderline personality disorder: a [11C]CURB positron emission tomography study

Amygdala-prefrontal cortex (PFC) functional impairments have been linked to emotion dysregulation and aggression in borderline personality disorder (BPD). Fatty acid amide hydrolase (FAAH), the major catabolic enzyme for the endocannabinoid anandamide, has been proposed as a key regulator of the amygdala-PFC circuit that subserves emotion regulation. We tested the hypothesis that FAAH levels measured with [¹¹C]CURB positron emission tomography in amygdala and PFC would be elevated in BPD and would relate to hostility and aggression. Twenty BPD patients and 20 healthy controls underwent FAAH genotyping (rs324420) and scanning with [¹¹C]CURB. BPD patients were medication-free and were not experiencing a current major depressive episode. Regional differences in [¹¹C]CURB binding were assessed using multivariate analysis of covariance with PFC and amygdala [¹¹C]CURB binding as dependent variables, diagnosis as a fixed factor, and sex and genotype as covariates. [¹¹C]CURB binding was marginally elevated across the PFC and amygdala in BPD (p = 0.08). In a priori selected PFC, but not amygdala, [¹¹C]CURB binding was significantly higher in BPD (11.0%, p = 0.035 versus 10.6%, p = 0.29). PFC and amygdala [¹¹C]CURB binding was positively correlated with measures of hostility in BPD (r > 0.4; p < 0.04). This study is the first to provide preliminary evidence of elevated PFC FAAH binding in any psychiatric condition. Findings are consistent with the model that lower endocannabinoid tone could perturb PFC circuitry that regulates emotion and aggression. Replication of these findings could encourage testing of FAAH inhibitors as innovative treatments for BPD.

Covariates of the Severity of Aggression in Sexual Crimes: Psychopathy and Borderline Characteristics

Whereas risk assessment literature on sexual offending has primarily focused on prediction of subsequent sexual crimes, and not the severity of those crimes, the first aim of the present study was to identify variables that predict the amount of damage to victims in sexual crimes compared with those that predict general aggressiveness. The second aim was to ascertain whether adding emotional instability measurements, as in borderline personality disorder (BPD), would add incremental variance to that captured by the facets of the Psychopathy Checklist-Revised (PCL-R). Trained raters assessed on the PCL-R, BPD, and measures of severity of sexual and nonsexual violence 302 adults who had sexually offended. PCL-R's Antisociality and two externalizing BPD factors (one from the standard and one from the alternative criteria) were significant predictors of violence both in sexual and nonsexual crimes. In contrast, deficits in the PCL-R's Affective facet (2) predicted victim damage in sexual contexts only, whereas the Lifestyle Impulsivity facet (3) of the PCL-R predicted violence in nonsexual contexts only. These findings suggest that adding measures of emotional dysregulation to commonly used instruments like the PCL-R, which assesses callousness and antisociality, may be beneficial for predicting violence.

The Salience of Antisocial Personality Disorder for Predicting Substance Use and Violent Behavior: The Moderating Role of Deviant Peers

Deviant peer association and antisocial personality disorder are risk factors for drug use and violent offending. However, there has yet to be research that focuses on how deviant peer association may moderate the impact of antisocial personality disorder on these outcomes. Data from Wave 10 of the Pathways to Desistance dataset were used in analyses. Negative binomial regression was used to estimate the effects of covariates on violent offending. Ordered logistic regression was used to estimate the effects of covariates on substance use outcomes. Results indicated that deviant peer association moderated the impact of antisocial personality disorder on violent offending frequency and marijuana use frequency. The direction of this interaction effect was positive for marijuana use. The direction of this moderation was negative for violent offending, indicating that antisocial personality disorder–diagnosed individuals commit fewer violent offenses at similar levels of deviant peer association as nonafflicted participants.

Homicidal Ideation and Forensic Psychopathology: Evidence From the 2016 Nationwide Emergency Department Sample (NEDS)

Homicide is the most serious and costly criminal offense and better forensic and criminological understanding of homicidal ideation as a potential psychobehavioral precursor to homicidal conduct is critical. Using data from the 2016 Nationwide Emergency Department Sample (NEDS) from the Healthcare Cost and Utilization Project (HCUP) distributed by the Agency for Healthcare Research and Quality (AHRQ), we found 64,910 cases of homicidal ideation among a sample of 25.6 + million-a prevalence of 0.25%. Numerous conditions conferred increased substantially the likelihood of homicidal ideation including antisocial personality disorder (2406%), schizoaffective disorder (1821%), borderline personality disorder (1557%), paranoid personality disorder (1,504%), schizophrenia (1,143%), obsessive-compulsive personality disorder (921%), brief psychotic disorder (771%), unspecified psychosis (737%), avoidant personality disorder (596%), and schizoid personality disorder (571%), delusional disorder (546%), and other psychotic disorder (504%). Homicidal ideation is comorbid with serious psychiatric and behavioral problems and has important implications for offender typologies and homicidality.

Post-traumatic stress disorder and having antisocial peers in adolescence are risk factors for the development of antisocial personality disorder

Antisocial personality disorder is a mental illness that is a major public health concern. Both post-traumatic stress disorder and association with antisocial peers have been found to be associated with increased risk for diagnosis of antisocial personality disorder. Despite this, past research has yet to examine the interrelatedness of these three constructs from a developmental perspective. This study sought to examine the effect of post-traumatic stress disorder in adolescence on the risk for antisocial personality disorder diagnosis in adulthood and the relevance of differences in developmental patterns of degree of association with antisocial peers in adolescence as an additional risk factor. The Pathways to Desistance data were used in analyses, comprising the longitudinal responses of 1,354 juvenile offenders who had recently been adjudicated for a serious offense prior to baseline measurement. Logistic regression was used to examine these relationships. Ever meeting criteria for post-traumatic stress disorder in adolescence significantly increased the odds of developing antisocial personality disorder in adulthood. This effect was no longer significant upon inclusion of variables pertaining to association with antisocial peers. Implications are discussed.
