Partner Violence Perpetration Research Articles

Changes in Mental Health, Emotional Distress, and Substance Use Affecting Women Experiencing Violence and Their Service Providers during COVID-19 in a U.S. Southern State.

Research conducted during the COVID-19 pandemic has revealed many unintended consequences of mandated safety precautions, including increased perpetration of intimate partner violence (IPV), increases in substance use, and worsening mental health conditions. We conducted a repeated, cross-sectional survey of survivors of IPV, a longitudinal survey of service providers working in an IPV shelter, and interviews with both. We conducted surveys at the beginning of the pandemic and nearly half a year later to assess mental health and, for clients, substance use. Results showed that two small samples of survivors living in the shelter in 2020 and 2021 experienced both mental health decline and increased use of substances. Qualitative data from in-depth interviews suggest that COVID-19-related restrictions mirrored survivors' experiences of power and control in violent relationships. Further, IPV service providers-essential workers during COVID-19-experienced stress associated with reports of burnout and mental fatigue. This study suggests that community-based organizations can help mitigate the impacts of COVID-19 on survivors of IPV but should avoid adding additional work for staff as service providers experienced mental and emotional stress.

Exposure to interparental violence and intimate partner violence among women in Papua New Guinea

IntroductionEvidence suggests that childhood exposure to interparental violence increases the risk of intimate partner violence (IPV) experience or perpetration in adolescence or adulthood. However, it is unclear if exposure to interparental violence increases the risk of IPV among women in Papua New Guinea. This study, therefore, seeks to fill this gap in the literature by examining the association between childhood exposure to interparental violence and IPV among women in Papua New Guinea.MethodsWe used data from the most recent 2016–18 Papua New Guinea Demographic and Health Survey. We included 3,512 women in our analyses. Past-year experience of IPV was the outcome variable in this study. Exposure to interparental violence was the key explanatory variable. We used a multilevel binary logistic regression to examine the association between exposure to interparental violence and IPV.ResultsWe found a higher probability of experiencing IPV among women exposed to interparental violence [aOR = 1.45, 95% CI = 1.13, 1.86] relative to women who were not exposed. Furthermore, we found that women living in rural areas had a lower likelihood of IPV experience [aOR = O.50, 95% CI = 0.32, 0.80] compared to those in urban settings. Finally, a greater odd of IPV experience was found among women staying in the Highlands Region [aOR = 1.44, 95% CI = 1.06, 1.96] compared to those staying in the Southern Region.ConclusionExposure to interparental violence was found to be significantly associated with IPV among women in Papua New Guinea. The findings of this study suggest the need for proven operational strategies to reduce IPV, such as improving anti-IPV laws in Papua New Guinea. We recommend the development and implementation of intercession strategies to reduce the experience and justification of violence among women exposed to interparental violence. In addition, health professionals should implement counseling and health education initiatives to tackle the consequences of IPV on women's well-being.

Factors Correlated With Sexual Assault Victimization Among College Students in the United States: A Meta-Analysis.

Sexual assault (SA) continues to be a serious problem on college campuses in the United States. This meta-analysis sought to identify correlates for SA victimization on college campuses, as well as examine if there were any differences in correlates for men and women. Database searches utilizing Boolean search terms were used to identify studies to be included in the meta-analysis. Studies were included if they provided quantitative data on correlates for SA victimization among college students. A total of 118 studies yielding 405 unique effect sizes were included in this study. The strongest correlates for SA victimization among college students were physical intimate partner violence (IPV) perpetration, physical IPV victimization, emotional IPV victimization, and prior SA victimization. Other significant correlates were related to mental health (e.g., hopelessness, suicidal ideation, trauma symptoms, anxiety symptoms, depressive symptoms), and factors related to a campus party culture (e.g., binge drinking, alcohol use, drug use, Greek membership). We were able to compare seven correlates between men and women. Results of the meta-analysis also highlight the need for future research to examine additional correlates for SA victimization, as well as examine race/ethnicity and gender as separate categories when trying to further understand correlates for SA victimization.

Longitudinal Associations Between Childhood Adversity and Adolescent Intimate Partner Violence in Malawi.

Adverse childhood experiences (ACEs)-including child maltreatment, witnessing violence, and household dysfunction-have been robustly associated with poor health in later life. There is also increasing evidence that those who experience childhood adversity are more likely subsequently to be victims or perpetrators of intimate partner violence (IPV). Most evidence, however, is cross-sectional and concentrated in high-income settings, and cannot be generalized to more diverse contexts. In contrast, this study assessed longitudinal relations between ACEs and IPV in a low-income country. We interviewed 1,878 adolescents in rural Malawi between 2017 and 2018 (aged 10-16) and again in 2021 (aged 13-20). Adolescents completed the Adverse Childhood Experience-International Questionnaire. Past-year physical, sexual, and emotional IPV victimization and perpetration were measured using the WHO's Violence Against Women Instrument. We estimated multivariate regression models between cumulative adversity (0-13 adversities) at baseline and IPV at follow-up among respondents who reported any romantic or sexual partnerships. The cumulative ACEs score was associated with emotional IPV victimization for boys (OR = 1.12 per ACE) and sexual IPV victimization for girls (OR = 1.18). The ACEs score demonstrated a significant association with perpetration for girls only (OR = 1.33 for emotional IPV). By using longitudinal data, we more rigorously demonstrated the critical role of childhood adversity in shaping later IPV behavior. There are ongoing efforts toward primary prevention of childhood adversity. Given the burden that adolescents already carry (six ACEs on average in our sample), we also need secondary interventions that can help interrupt the pathway from adversity to IPV. This calls for increased collaboration between those working to address violence against children and violence against women.

Perpetration of Intimate Partner Violence and COVID-19-Related Anxiety During the Second Lockdown in Portugal: The Mediating Role of Anxiety, Depression, and Stress.

The restrictions imposed during lockdown by COVID-19 pandemic entailed increased risks for the perpetration of intimate partner violence (IPV). Widespread fear and uncertainty related to the virus and the policies adopted to contain it have been linked to a set of social, emotional, and economic stressors that can increase the risk of IPV. The present study aims to assess the association between COVID-19-related anxiety, psychological distress (depression, anxiety, and stress), and IPV perpetration in the community, as well as to assess the mediating role of psychological distress and depression, anxiety, and stress in the relationship between COVID-19-related anxiety and the perpetration of IPV. A sample of 336 participants (282 females, Mage = 34.91, SD = 11.72) was recruited from the Portuguese population through an online self-report questionnaire, completed after the second lockdown (from April and July 2021). High rates of IPV perpetration during the confinement, in particular psychological and physical IPV, were found. COVID-19-related anxiety and psychological distress (depression, anxiety, and stress) were related to higher levels of IPV perpetration. Psychological distress and stress mediated the relationship between COVID-19-related anxiety and total IPV perpetration and psychological distress and depression mediated the relationship between COVID-19-related anxiety and psychological IPV perpetration. This study highlights the mediating role of psychological distress on IPV perpetration. Practical implications for intervention policies in IPV perpetration will be discussed.

Dyadic effects of minority stress and problematic alcohol use on sexual intimate partner violence in same sex couples.

Little is known about the factors that facilitate the perpetration of sexual violence within the context of same-sex romantic relationships (sexual intimate partner violence perpetration [S-IPV]). The present study sought to identify the effects of external and internal minority stress and problematic drinking on perpetration of S-IPV within a dyadic framework. A community-based sample of 137 sexual and gender minority (SGM) couples (N = 274; 59 male assigned at birth and 78 female assigned at birth couples) completed self-report surveys about minority stressors, alcohol use, and S-IPV perpetration. Multilevel logistic regression analyses were conducted within an actor-partner interdependence framework. This approach accounted for both actor effects (e.g., how much one's S-IPV perpetration is predicted by their own risk factors) and partner effects (e.g., how much one's S-IPV perpetration is influenced by their partner's risk factors). Both Actor external minority stress and internal minority stress were positively associated with Actor S-IPV perpetration. Actor problematic drinking was not associated with Actor S-IPV perpetration; however, Partner problematic drinking was positively associated with Actor S-IPV perpetration. Observed effects were robust above the addition of other risk factors. This research innovatively extricates S-IPV perpetration from other forms of IPV and indicates that Actor minority stress and Partner problematic drinking increase S-IPV likelihood. Results serve as a starting point for development of etiological models to inform the design of culturally-informed interventions to reduce S-IPV among SGM couples.

The Interaction between Attention Deficit Hyperactivity Disorder and Neuropsychological Deficits for Explaining Dropout and Recidivism of Intimate Partner Violence Perpetrators

Objective: Even though previous research has identified the negative impact of the attention deficit hyperactivity disorder (ADHD) in intimate partner violence (IPV) perpetration, less is known regarding the moderator factors that explain this association. In this study, we first aimed to assess whether there would be differences in terms of specific neuropsychological variables (e.g., IQ, working memory, executive functioning, and emotion decoding) between different groups of IPV perpetrators, affected or not by ADHD, and also compared with non-violent men (without ADHD). Second, we evaluated differences in dropout and recidivism among the subgroups of IPV perpetrators. Third, we assessed whether ADHD interacts with neuropsychological functioning to explain treatment compliance (dropout) and official recidivism among IPV perpetrators. Method: We administered a set of neuropsychological tests and self-reports to a group of IPV perpetrators with ADHD (n = 161), without ADHD (n = 163), and non-violent men (n = 103). Data on IPV perpetrators’ treatment compliance and official recidivism were collected after treatment. Results: Our results indicated that all the groups of IPV perpetrators presented worse performance in all cognitive domains than controls. Furthermore, ADHD IPV perpetrators also showed worse performance in all cognitive domains than IPV perpetrators without ADHD, except for emotion decoding abilities. Most importantly, the combined subtype of ADHD IPV perpetrators presented the highest rate of dropout and official recidivism. Lastly, ADHD diagnosis and neuropsychological impairments separately offered a considerable explanation of treatment compliance and recidivism but their combination did not increase the amount of explained variance. Conclusions: Our study highlights the need to implement good screening processes for correctly diagnosing IPV perpetrators and, consequently, designing more effective intervention programs.

Programme responses for men who perpetrate intimate partner violence in the context of alcohol or other drugs: a scoping review

PurposeSubstance use plays a significant role in the perpetration of much intimate partner violence (IPV). However, responses to these two issues are rarely integrated. Single focus programme responses can lead to poor outcomes for men as well as their families experiencing these intersecting issues. This scoping paper aims to establish the current state of knowledge on contextual factors influencing the development and implementation of combined programmes.Design/methodology/approachFour electronic databases were systematically searched in May 2021 and December 2021. Twenty-one peer-reviewed studies reporting on ten programmes were included.FindingsThis scoping review revealed that combined programme responses are an underdeveloped area of research and evaluation. The limited evidence base indicated systemic barriers hindering services’ capacity to expand this field of work, affecting implementation and outcomes. Support is required from the wider service systems to intervene in men’s perpetration of IPV in the context of substance use.Practical implicationsFindings in this scoping review demonstrate the importance of fostering a coordinated and collective response to IPV in the context of substance use. Combined programmes have the potential to reduce siloed practices, enabling more holistic responses for men with intersecting issues. However, researchers and policymakers must also address contextual issues hindering or enabling combined programmes’ implementation and development.Originality/valueMapping the evidence based on combined programmes provides direction for further development and research to expand this field of inquiry.

Characteristics of Male Perpetrators of Intimate Partner Violence in South-South Nigeria

Aims: This study was done to identify personal characteristics of men that may be associated with partner abuse in order to provide a basis for offering counseling services, to prevent, as well as appropriately manage cases of existing abuse.
 Study Design: Cross sectional survey.
 Place and Duration of Study: The study was done at the General Outpatients Clinic of University of Port Harcourt Teaching Hospital, Port Harcourt, Rivers State, Nigeria; between August and November 2007.
 Methodology: The examiner administered pre-tested questionnaire on adult females attending the clinic within the duration of the study. Every second patient seen by the investigator on the waiting line of a regular medical consultation visit that consented to the study was recruited until the desired sample size was got. Socio-demographic as well as drug use information of adult subjects’ partners aged between 18 to 59 years was obtained.
 Results: Of the 384 females investigated, age 21 – 67 years with a mean age of 31.31±8.61 years: physical abuse 41.9%, verbal/emotional abuse 49.0%, and a combined (physical/verbal) abuse 29.9%. Partners’ education had statistically significant relationship with physical abuse, P=0.018; partners’ tobacco uses with verbal abuse (P=0.000), and between combined abuse and use of tobacco or cannabis, P=0.003 and 0.048 respectively.
 Linear multiple regression model of physical abuse parameters: throw something at, being pushed, slapped, kicked, hit at, beaten-up, threatened or weapon used, and forced sex; P-value was 0.000, with sum of squares 60.263 and degree of freedom 9. Whereas for verbal abuse: cajoled, derogatory statements made at, name calling, and shout at, as abuse parameters; P-value was 0.000, sum of squares 72.763 and degree of freedom, 4. Both of these were statistically significant.
 Conclusion: This study demonstrates a higher perpetration of verbal/emotional violence than that of physical violence (or both) by males on their partners with lack of formal education, with tobacco and/or cannabis use, as aggravating factors.

Profiles of Childhood Victimization as Predictors of Sexual Aggression and Intimate Partner Violence Perpetration.

The study utilized a latent profile analysis to evaluate distinct combinations of men's childhood victimization experiences and their communal predictive ability for sexual aggression (SA) and intimate partner violence (IPV) perpetration. Men living in the United States (N = 399) completed assessments of emotional, physical, and sexual childhood victimization, as well as SA and IPV toward women. The results indicated that members of profiles characterized by moderate to high frequencies of childhood victimization-especially sexual victimization-were at increased risk of SA and IPV perpetration. Contrary to expectations, adult- versus peer-perpetrated victimization did not appear to substantially alter risk of perpetration.

Childhood exposure to parental violence, attachment insecurities, and intimate partner violence perpetration among Arab adults in Israel

BackgroundExtensive research supports the existence of a “cycle of violence” that links exposure to parental violence during childhood (i.e., witnessing interparental violence and child maltreatment) with intimate partner violence (IPV) perpetration. However, there is still a need to explore the mechanisms through which early exposure to parental violence may foster IPV perpetration during adulthood. ObjectiveIn this study, we examine the mediating role of attachment insecurities and gender differences in the relationship between exposure to parental violence during childhood and IPV perpetration during adulthood. Method, participants, and settingWe conducted a cross-sectional survey among a representative sample of 604 married Arab adults (M age = 33.5, SD = 6.52; 50.1 % women) in Israel using a self-administered questionnaire. ResultsExposure to physical violence, both as a victim and indirectly as a witness in childhood, was found positively correlated with adulthood IPV perpetration, with effect sizes ranging from weak (f2 = 0.01) to moderate (f2 = 0.15). Further, attachment-related avoidance was found to mediate the association between witnessing interparental physical violence and IPV perpetration. Gender differences were found in this relationship, with a stronger association indicated among male participants than among females. ConclusionExposure to physical violence may be understood as a risk factor for IPV perpetration directly and indirectly through the development of attachment-related avoidance.

Detecting intimate partner violence circumstance for suicide: development and validation of a tool using natural language processing and supervised machine learning in the National Violent Death Reporting System

Mental and Physical Health Correlates for Emotional Intimate Partner Violence Perpetration and Victimization: A Meta-Analysis.

Approximately 50% of both men and women will experience emotional intimate partner violence (IPV) in their lifetime-a form of violence highly associated with other forms of IPV-making it important to develop further understanding of for assessment and treatment purposes. The bio-psycho-social model was used to guide the study. Utilizing data from 181 studies, yielding 348 effect sizes, we conducted a meta-analysis examining mental and physical health correlates with emotional IPV perpetration and victimization. We also examined if mental and physical health correlates were significantly stronger for emotional IPV perpetration or victimization, as well as if correlates were stronger for men or women. Suicidal ideation, post-traumatic stress, anxiety, depressive symptoms, borderline personality disorder (PD), psychological distress, physical pain, trauma, anger, shame, poor physical health, antisocial PD, and somatic symptoms were significantly associated with emotional IPV victimization. Borderline PD, narcissism, emotional dysregulation, anger, post-traumatic stress, antisocial PD, psychopathy, depressive symptoms, anxiety symptoms, and trauma were significantly associated with emotional IPV perpetration. Anger, emotional dysregulation, and psychopathology were stronger correlates for emotional IPV perpetration compared to victimization, and post-traumatic stress disorder (PTSD) and psychological distress were stronger correlates for victimization. PTSD and suicidal ideation were stronger correlates of IPV victimization for women than men, and anger was a significantly stronger correlate of IPV perpetration for women than men. This study highlights the importance of a holistic approach when working with victims and perpetrators of IPV, focusing on the importance of taking all aspects of the bio-psycho-social model into account.

Dropout and recidivism are partly explained by emotional decoding and perspective taking deficits of intimate partner violence perpetrators.

Professionals and researchers have dedicated important efforts to understanding the underlying factors that explain the failure to complete interventions (dropout) and the recidivism of men convicted of intimate partner violence (IPV) against their female partners. There is a growing interest in measuring emotional decoding and empathic deficits in IPV perpetrators to better understand dropout and recidivism proneness, due to their direct impact on behavioral regulation. In the current study, we first aimed to examine whether the emotional decoding abilities of facial expressions and empathic abilities (cognitive and emotional), as well as their interrelationships in IPV perpetrators (n = 561), would explain dropout, treatment attendance, and recidivism (risk and official) once treatment ended. Our results allowed us to conclude that emotional decoding abilities and perspective taking (cognitive empathy) were significantly and negatively associated with dropout and recidivism. Two moderation models were significant. On the one hand, participants with low emotional decoding abilities presented lower intervention doses the lower their perspective taking. Furthermore, the percentage of participants that reoffended was higher among individuals with low and moderate perspective taking who dropped out. Therefore, our study highlights the importance of conducting emotional decoding and empathic assessments during the initial stages of intervention programs to clearly outline the therapeutic needs of IPV perpetrators. This would allow designing coadjuvant and complementary training programs that can support the main interventions by increasing treatment adherence and, in turn, reducing the risk of recidivism.

Reported Perpetration of Intimate Partner Violence among Adolescent Girls: Motivations and IPV Victimization

Background: Studies on intimate partner violence (IPV) perpetration by girls and women have found self-defense is a common motivation. Current items—namely the abbreviated items from the Conflicts Tactics Scale (CTS)—used to measure IPV perpetration may be counting these girls/women as perpetrators when they are victims of IPV. The purpose of this study was to assess adolescent girls’ IPV perpetration, including (a) motivations and (b) factors associated with reports of adolescent girls’ perpetration of IPV using standard abbreviated CTS measures. Methods: This study utilized cross-sectional survey data collected from 159 participants in an urban Southern California clinic in 2016–2018. Demographic variables—age, ethnicity, current school enrollment, living situation and born in the U.S.—were analyzed with chi-square or independent t-tests. Frequency analyses were used to quantify motivations for IPV perpetration. Crude and adjusted logistic regression models assessed key variables associated with female adolescents’ IPV perpetration: victimization, drug use, alcohol day, binge drinking, depression, anxiety, and suicide ideation. A final multivariate model further adjusted for IPV victimization. Results: The average age of participants was 17 years old, and the majority of participants were Hispanic. Primary motivations for adolescent girls’ IPV perpetration included self-defense. Adolescent girls who reported IPV perpetration had significantly greater odds of victimization [95% CI = 4.31–32.07], drug use [95% CI = 1.14–6.99], binge drinking [95% CI = 1.08–6.87], and suicide ideation [95% CI = 1.13–10.62]. These findings remained significant in models adjusted for significant demographics. In the final multivariate regression model adjusted for IPV victimization, none of these factors remained significantly related to adolescent girls’ IPV perpetration. Conclusions: Findings establish a connection between victimization, self-defense, and adolescent girls’ IPV perpetration. These findings add to existing literature suggesting that the CTS measures of perpetration may encompass both IPV victimization and perpetration when used with populations of girls and women.

Reduced vagal tone in intimate partner violence perpetrators is partly explained by anger rumination

Polyvagal theory proposed that an autonomous nervous system imbalance might be characteristic of violent individuals, especially reduced parasympathetic or vagal tone. Accordingly, some studies concluded that when intimate partner violence (IPV) perpetrators deal with acute stress, they tend to present a sympathetic predominance over the parasympathetic nervous system once the stress has ended. However, less is known about cognitive mechanisms that explain this phenomenon. In fact, this functioning might be explained by inner speech and/or angry thoughts (anger rumination) in reactive aggressors. Nonetheless, there is a gap in the scientific literature assessing whether this psychophysiological functioning in IPV perpetrators is explained by anger rumination. For this reason, the first aim of this study was to assess the cardiorespiratory (heart rate (HR), pre-ejection period (PEP), and respiratory sinus arrhythmia (RSA)) and electrodermal (skin conductance level (SCL)) changes, as well as the anger state, when coping with an acute laboratory stressor, comparing a group of reactive IPV perpetrators (n = 47) and a group of non-violent men (n = 36). The second aim was two-fold. After checking whether the groups differed on their anger rumination and manifestation of aggression (reactive and/or proactive) scores, we studied whether these variables explained psychophysiological and psychological responses to a laboratory task (changes and levels during the recovery period) in each group. Our results demonstrated that, compared to the control group, IPV perpetrators presented lower RSA levels (vagal tone). Even though the groups did not differ on their anger rumination or manifestation of aggression scores (except for proactive aggression), only in the IPV perpetrators, high anger rumination and reactive aggression partly explained the lower vagal tone (RSA levels) and high levels of anger state at post-task. Consequently, this study contributes to understanding the psychobiological basis for violence proneness in IPV perpetrators, making it possible to explore new therapeutic strategies.

Influence of Ambivalent Sexism on Intimate Partner Violence Tolerance and Mental Violence in a Chinese Female Sample: Relationship Causality Orientation as a Moderator.

The current study examined how the general tolerance of women's intimate partner violence and mental violence perpetration are affected by women's ambivalent sexism and relationship causality orientation. One hundred and forty-nine of 221 Chinese female participants recruited on an online platform were included in the final data analysis. The results showed that causality orientation plays a moderating role. Specifically, as controlled orientation increased, the relationship between hostile sexism and intimate partner violence tolerance became stronger. As the autonomous orientation increased, the relationship between benevolent sexism and intimate partner violence tolerance became weaker. Hostile sexism and controlled orientation positively predict women's mental violence perpetration.
