Personality Disorder Traits, Trauma, and Risk in Perpetrators of Domestic Violence

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.

Personality disorders (PD) and interpersonal violence (IV) during COVID-19 pandemic: a systematic review

Not only did the ongoing CoronaVIrus Disease-19 (COVID-19) pandemic cause a massive number of casualties, but also there is growing concern that the burden of its psychological aftermaths will only show up years down the road. This systematic review summarises the existing literature reporting the impact of COVID-19 on personality disorders (PDs)-related violence. MEDLINE and APA PsycINFO were independently searched for relevant studies by two authors. Eligible studies had to be identifiable through database searching, published and fully accessible. This systematic review was conducted according to Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. An initial pool of 241 studies were found, out of which 69 met the selection criteria and were, therefore, included. The majority reported a worse Mental Health Outcome (MHO) during the pandemic as related to dysfunctional personality and positive personality traits predicting a better outcome. Furthermore, increased levels of interpersonal violence (IV) and self-directed violence were reported. Further research should be conducted on the reciprocal interaction of PDs and IV during the time of pandemic. Nevertheless, the dramatic impact of restrictive measures on PDs has still to be appropriately addressed.

Intimate Partner Violence and Mental Health during Lockdown of the COVID-19 Pandemic

BACKGROUND

This study took place in the context of the COVID-19 pandemic. The present research assesses the association between lockdown conditions (such as time spent at home, living environment, proximity to contamination and social contacts), mental health (including intolerance of uncertainty, anxiety and depression) and intimate partner violence within the community. This study evaluates the indirect effect of anxiety and depression on the relationship between intolerance of uncertainty and intimate partner violence (physical assault and psychological aggression).

METHODS

1532 adults (80.8% of women, Mage = 35.34) were recruited from the Belgian general population through an online self-report questionnaire completed during the lockdown (from April 17 to 1 May 2020).

RESULTS

The results demonstrate that the prevalence of physical assault (including both perpetration and victimization) was significantly higher in men, whereas the prevalence of psychological aggression was significantly higher in women. Men reported significantly more violence during lockdown. Women, on the other hand, were more anxious and more intolerant of uncertainty. No difference between men and women was found for depression. Anxiety and depression significantly mediated the relationship between intolerance of uncertainty and physical assault and psychological aggression. Sex did not moderate the mediation.

CONCLUSION

Clinical implications for public health policy are highlighted.

Differential MCMI-III psychopathological profiles between intimate partner violence perpetrators with and without childhood family violence

This study explored the differential prevalence of personality disorders (PD) and clinical syndromes between male perpetrators of intimate partner violence (IPV) with and without a history of childhood family violence (CFV). A sample of 981 perpetrators of IPV was assessed with the Millon Clinical Multiaxial Inventory-III (MCMI-III). Comparisons of sociodemographic characteristics and MCMI-III scales' scores between perpetrators with (n = 293) and without (n = 688) CFV were carried out. Results showed that IPV perpetrators with CFV had a lower level of education, were less frequently employed, and had higher rates of previous psychiatric history than perpetrators without CFV. Statistically significant differences between groups in almost all the MCMI-III scales were found. Perpetrators with CFV presented with higher scores on most of the evaluated scales and showed a more severe psychopathological profile than perpetrators without CFV. The multivariate analysis showed that the main MCMI-III domains related to CFV were higher scores on the disclosure and alcohol dependence scales and lower scores on the passive-aggressive scale. These findings reveal that CFV is associated with a more severe psychopathological profile in perpetrators of IPV. In order to develop tailored interventions, the presence of CFV and psychopathological symptoms should be assessed in IPV perpetrators.
