Violent experiences in childhood are associated with men's perpetration of intimate partner violence as a young adult: a multistage cluster survey in Malawi

OBJECTIVE: Intimate partner violence (IPV) is a huge public health problem. The aim of the study was to estimate the prevalence and influence of sociodemographic and health characteristics on IPV victimization and perpetration among women and men 15 years and older in South Africa.MATERIALS & METHODS: Data based on the South African national population-based survey in 2012 for 15916 (8532 women and 7384 men) aged 15 years and older who were in an intimate partner relationship were analysed. Bivariate and multivariable logistic regression was conducted to assess the association between sociodemographic factors, health variables and IPV victimization and perpetration.RESULTS: Among women, 8.5% had experienced any form of IPV in the past 12 months, and 3.5% of the women had engaged in IPV perpetration in the past 12 months. Among men, 5.0% had experienced any form of IPV in past 12 months, and 4.4% of the men had engaged in IPV perpetration in the past 12 months. In multivariable logistic regression analysis among women, younger age, being African Black, having psychological distress, having been a victim of violent crime and having had multiple sexual partners were associated with IPV victimization in the past 12 months, while younger age, psychological distress, hazardous or harmful alcohol use, and having had multiple sexual partners was associated with IPV perpetration in the past 12 months. In multivariable logistic regression analysis among men, younger age, psychological distress, hazardous or harmful alcohol use, and having been a victim of violence crime was associated with IPV victimization in the past 12 months, while younger age, poor health status, psychological distress, hazardous or harmful alcohol use, and illicit drug use was associated with IPV perpetration in the past 12 months.CONCLUSION: Past 12-month prevalence of IPV victimization and perpetration among women and men was significant. IPV gender commonalities and differences in risk factors, such as psychological distress, substance use, crime victimization and sexual risk behaviour, may inform strategies of violence prevention programmes.

Intimate partner violence (IPV) may increase women's HIV acquisition risk. Still, knowledge on pathways through which IPV exacerbates HIV burden is emerging. We examined the individual and partnership-level characteristics of male perpetrators of physical and/or sexual IPV and considered their implications for women's HIV status. We pooled individual-level data from nationally representative, cross-sectional surveys in 27 countries in Africa (2000-2020) with information on past-year physical and/or sexual IPV and HIV serology among cohabiting couples (≥15 years). Current partners of women experiencing past-year IPV were assumed to be IPV perpetrators. We used Poisson regression, based on Generalized Estimating Equations, to estimate prevalence ratios (PR) for male partner and partnership-level factors associated with perpetration of IPV, and men's HIV status. We used marginal standardization to estimate the adjusted risk differences (aRD) quantifying the incremental effect of IPV on women's risk of living with HIV, beyond the risk from their partners' HIV status. Models were adjusted for survey fixed effects and potential confounders. In the 48 surveys available from 27 countries (N = 111,659 couples), one-fifth of women reported that their partner had perpetrated IPV in the past year. Men who perpetrated IPV were more likely to be living with HIV (aPR = 1.09; 95%CI: 1.01-1.16). The aRD for living with HIV among women aged 15-24 whose partners were HIV seropositive and perpetrated past-year IPV was 30% (95%CI: 26%-35%), compared to women whose partners were HIV seronegative and did not perpetrate IPV. Compared to the same group, aRD among women whose partner was HIV seropositive without perpetrating IPV was 27% (95%CI: 23%-30%). Men who perpetrated IPV are more likely to be living with HIV. IPV is associated with a slight increase in young women's risk of living with HIV beyond the risk of having an HIV seropositive partner, which suggests the mutually reinforcing effects of HIV/IPV.

To better understand the underlying mechanisms of intimate partner violence (IPV) perpetration, this study examined the direct and sequential indirect associations between the cumulative childhood interpersonal trauma (CCT), Dark Triad personality traits, empathy skills, and IPV perpetration (physical, psychological, sexual, and coercive control) among men entering treatment for IPV-related issues. In a cross-sectional survey, a sample of 1418 Canadian men was recruited through a unique partnership with community organizations specializing in IPV treatment. Participants completed self-report questionnaires online, which assessed CCT, personality, empathy, and perpetrated IPV. A path analysis model was conducted to test direct and indirect associations. Results revealed that higher CCT in men was associated with higher IPV perpetration (psychological, coercive control) sequentially through all three personality traits (narcissism, Machiavellianism, psychopathy), and more contradictory emotions (affective dissonance) to those of others. Other direct (i.e. CCT-higher psychological IPV) and indirect (e.g. CCT-more psychopathy-higher physical IPV) associations were also observed and discussed. Findings provide valuable insights into intervention targets to reduce and prevent IPV perpetration. Specifically, the high prevalence of CCT among IPV perpetrators underscores the need to incorporate this factor in clinical assessments. Practitioners are encouraged to target the contradictory emotional responses of perpetrators toward others, as dissonant empathy plays a significant role in the risk of IPV perpetration.

To expand the scientific literature on how resting state functional connectivity (rsFC) magnetic resonance imaging (MRI) (or the measurement of the strength of the coactivation of two brain regions over a sustained period of time) can be used to explain treatment compliance and recidivism among intimate partner violence (IPV) perpetrators. Therefore, our first aim was to assess whether men convicted of IPV (n = 53) presented different rsFC patterns from a control group of non-violent (n = 47) men. We also analyzed if the rsFC of IPV perpetrators before staring the intervention program could explain treatment compliance and recidivism one year after the intervention ended. The rsFC was measured by applying a whole brain analysis during a resting period, which lasted 45 min. IPV perpetrators showed higher rsFC in the occipital brain areas compared to controls. Furthermore, there was a positive association between the occipital pole (OP) and temporal lobes (ITG) and a negative association between the occipital (e.g., occipital fusiform gyrus, visual network) and both the parietal lobe regions (e.g., supramarginal gyrus, parietal operculum cortex, lingual gyrus) and the putamen in IPV perpetrators. This pattern was the opposite in the control group. The positive association between many of these occipital regions and the parietal, frontal, and temporal regions explained treatment compliance. Conversely, treatment compliance was also explained by a reduced rsFC between the rostral prefrontal cortex and the frontal gyrus and both the occipital and temporal gyrus, and between the temporal and the occipital and cerebellum areas and the sensorimotor superior networks. Last, the enhanced rsFC between the occipital regions and both the cerebellum and temporal gyrus predicted recidivism. Our results highlight that there are specific rsFC patterns that can distinguish IPV perpetrators from controls. These rsFC patterns could be useful to explain treatment compliance and recidivism among IPV perpetrators.

Should we reconsider anger management when addressing physical intimate partner violence perpetration by alcohol abusing males? A systematic review

The Stability of Intimate Partner Violence Perpetration From Adolescence to Emerging Adulthood in Sexual Minorities

Several studies have provided evidence that antisocial, borderline and narcissistic personality traits of intimate partner violence (IPV) perpetrators significantly increase proneness to violence. In addition, an imbalance between testosterone (T) and cortisol (C) levels has been observed in this population, making individuals prone to violence. We aimed to establish whether IPV perpetrators differ in personality traits, T/C ratio and anger expression from controls, and also to examine the moderating role of the T/C ratio in the relationship between personality traits and anger expression. The sample consisted of 16 IPV perpetrators and 20 controls. T/C ratio was obtained as the quotient between salivary T and C levels. Anger expression and personality traits were measured with STAXI-2 and MCMI-III, respectively. Our results indicate that IPV perpetrators have higher antisocial, borderline and narcissistic personality traits and anger expression than controls. Nonetheless, they did not differ in basal T/C ratio. Finally, only in IPV perpetrators there was a positive relationship between these variables, the T/C ratio playing a moderating role in the relationship of antisocial and borderline traits with anger expression. In IPV perpetrators the T/C ratio may explain why certain personality traits are associated with high risk of becoming violent.

The autonomic nervous system (ANS) functioning has been proposed as a relevant method to characterize the therapeutic needs of intimate partner violence (IPV) perpetrators. Nevertheless, research has neglected the influence of the ANS on socio-affective functions in this population. The aim of the present study was to analyze the psychophysiological activity of IPV perpetrators (n = 52) compared to controls (n = 46) following an empathic induction task, performed through negative emotion-eliciting videos. We employed two general ANS markers (heart rate [HR] and respiratory rate [RR]), two sympathetic-related indexes (pre-ejection period [PEP] and skin conductance level [SCL]) and a parasympathetic biomarker (respiratory sinus arrhythmia [RSA]). Additionally, we explored the impact of psychophysiological activity on prosocial behavior using Hare's donation procedure. Compared to controls, IPV perpetrators reported lower HR and SCL following the task, as well as longer PEP, suggesting an attenuated sympathetic response to others' distress. No differences in the RSA response pattern were found, however, IPV perpetrators displayed lower overall RSA levels throughout the protocol, indicative of reduced parasympathetic activity. Besides, while no differences in prosocial performance were observed, greater sympathetic responses and overall parasympathetic activity predicted increased donations across the sample. Thus, a high sympathetic and parasympathetic activity might influence the occurrence of prosocial behavior. The present study provides further evidence supporting that IPV perpetrators cope differently with others' negative emotions. In line with this biopsychosocial perspective, insights are gained on the emotional processing of IPV perpetrators which, in turn, could contribute to improve IPV psychotherapeutic programs.

Differential cognitive profiles of intimate partner violence perpetrators based on alcohol consumption.

Antisocial, borderline, and narcissistic personality traits have been described as characteristics of intimate partner violence (IPV) perpetrators. Furthermore, deficits in cognitive empathy and impairments in emotional decoding processes may at least partially explain conduct disorders and social dysfunction in general. However, previous research has not explored potential associations between empathy deficits and the aforementioned traits or whether they are reflected in recidivism in IPV perpetrators. Accordingly, the main aim of this study was to explore associations between empathy deficits, antisocial, borderline, and narcissistic traits and the risk of recidivism in this population. The sample consisted of 144 IPV perpetrators (mean age = 41 years). High antisocial and borderline personality traits in this sample were associated with a high risk of recidivism, these relationships being moderated by poor empathy skills. Moreover, in IPV perpetrators with both antisocial and borderline personality traits, the risk of recidivism was higher than in those with only one of these traits. In contrast, narcissistic traits were unrelated to the risk of recidivism and impairments in empathy. The results of our study highlight the importance of empathy deficits and may help professionals to develop specific intervention programs focusing on improving empathy skills in antisocial and borderline IPV perpetrators.

Research indicates that experiences of intimate partner violence (IPV) are common among young gay, bisexual, and other young men who have sex with men (YMSM). Yet, there is little understanding of the individual, mental health, and psychosocial variables associated with IPV in this population. The aim of this study is to assess the prevalence and correlates of IPV among a new generation of racially/ethnically diverse YMSM. Baseline data from a longitudinal cohort study of YMSM (N = 598) from New York City informed lifetime experiences of IPV victimization, perpetration, and mutual IPV (those reporting both victimization and perpetration). Multivariate logistic regression models were constructed to examine associations between IPV and individual, mental health, and psychosocial factors. Among YMSM, 39% reported IPV victimization, 31% reported perpetration, and 25% reported mutual IPV. Victimization and perpetration were highly correlated. Childhood mistreatment was related to all three IPV outcomes. With regard to psychosocial states, impulsivity was the only variable strongly related to all three IPV outcomes. PTSD was significantly related to IPV victimization but not IPV perpetration. In addition, personal gay-related stigma was associated with IPV victimization, whereas public gay-related stigma was associated with IPV perpetration. Findings extend previous research by identifying psychosocial and mental health variables associated with IPV, while controlling for childhood mistreatment. We recommend more systematic screening for IPV in healthcare settings that serve YMSM (e.g., HIV testing sites). Moreover, we suggest that IPV may be part of a larger syndemic disproportionately burdening YMSM.

The goal of this naturalistic study was to examine heterogeneity among female and male civil psychiatric patients with a history of intimate partner violence (IPV) perpetration. Participants were 567 patients drawn from the MacArthur Violence Risk Assessment Study (J. Monahan et al., 2001). The authors examined subtype composition among 138 women and 93 men with positive histories of IPV and compared these groups with 111 women and 225 men with no histories of IPV. Findings for men and women were consistent with reports from studies of male perpetrators in forensic and community settings in that generally violent/antisocial, borderline/dysphoric, and family only/low-psychopathology subtypes of perpetrators were identified in both men and women. This study provides preliminary evidence for the generalizability of typologies derived from nonpsychiatric partner violence perpetrators to psychiatric populations and suggests that typologies derived from studies of male IPV perpetrators may provide useful guidance for the investigation of female IPV perpetration.
