Risk factors for physical violence against partners in the U.S
Psychology of Violence, 2014
Objective: To examine unique and relative predictive values of demographic, social learning, developmental, psychopathology, and dyadic variables as risk factors for perpetration of intimate partner physical aggression in a national sample of married or cohabiting individuals. Method: Men (n = 798) and women (n = 770) were selected from the public use data file of the 2003 National Comorbidity Survey Replication (NCS-R) which used a multistage cluster sampling design. Results: Eight percent of women and 5% of men reported perpetrating physical aggression in the past year. Based on multivariable regression analyses, among men, the unique risk factors for perpetrating physical aggression were parental violence, dating before age 14, dating aggression, Intermittent Explosive Disorder (IED) before and after age 20, and being victimized by partner. Among women, significant risk factors were younger age, dating aggression, IED before age 20, cohabiting, victimization by partner, and marital/relationship strain. Conclusions: A number of social learning, developmental, adult psychopathology, and dyadic factors were significant. Two dyadic variables, victimization and marital strain, had by far the strongest associations with perpetration of partner aggression. Given that dating aggression and early IED were risk factors for male and female IPV much later in life suggests early interventions for those at risk.
Trauma, violence & abuse, 2012
Intimate partner violence (IPV) is widespread. Several risk factors are associated with IPV perpetuation, including alcohol use and educational level. The aggression and violence associated with traumatic brain injury (TBI) suggest that brain trauma may also be a risk factor for IPV. To examine the association between TBI and IPV, the authors conducted a meta-analysis of peer-reviewed published studies reporting the prevalence of TBI in IPV perpetrators. The authors compared the frequency of TBI among IPV perpetuators to estimates of TBI in the general population using a single-sample test of proportions. Six studies containing a total of 222 subjects met inclusion criteria. Fifty-three percent (119) of the IPV perpetuators had a history of TBI, a prevalence significantly higher (p < .0001) than estimates of TBI in the general population. The prevalence of TBI among perpetuators of IPV appears significantly higher than the prevalence of TBI in the general population. To the exten...
Aggressive Behavior, 2015
We studied intimate partner violence (IPV) within a framework of other violent and nonviolent offending, to explore whether the risk factors for offending were similar across the different offense categories, and also for men and women. A comprehensive measure of offending behavior was administered to 184 men and 171 women, together with measures of anger, self-control, and psychopathic traits. The measure, the nonviolent and violent offending behavior scale (NVOBS), assesses IPV, general violence, and nonviolent offending behavior. Men perpetrated higher levels of general violence and nonviolent offenses than women, whereas women perpetrated significantly more IPV than men. Regression analyses showed that the predictors of offending behavior are generally similar for men and women, with the exception of IPV, where self-control was a better predictor of IPV for men and anger was a better predictor of IPV for women. Limitations of the present sample and suggestions for future work are discussed. Aggr. Behav. 9999:1-9, 2015.
The Role of Executive Function Deficits in Domestic Violence Perpetration
PsycEXTRA Dataset, 2014
Of the probable psychological or neuropsychological vulnerabilities or risks in domestic violence perpetration, deficits in executive function may be one of the least explored. This integrative review contains overviews of domestic violence theory, the literature on psychological and neuropsychological risk for violence, the literature on executive function, and the literature on coping. The neuropsychology and neuroanatomy of violence typically involves deficits in the frontal lobes and their role in cognition and impulse control and/or excessive activation of the limbic structures with their role of mediating primary emotions and drive-related behavior. Domestic violence perpetration can be understood as maladaptive and destructive coping, symptomatic of disorders of impulsivity, neuropsychological impairment, and emotional dysfunction activated within the context of intimacy or primary relationships, often (if not usually) exacerbated by substance abuse or dependency. Conceptualizing domestic violence perpetration as maladaptive coping, impaired by executive deficits, psychopathology, often worsened by substance abuse, opens up a wide range of alternative intervention strategies. Instead of assuming (often incorrectly) that a perpetrator's intentions are only patriarchal domination, careful assessment of neuropsychological vulnerability and coping abilities can lead to both a more accurate picture of risk as well as guided change strategies. Assessment of executive function can provide a framework for understanding and improving both the cognitive capabilities of perpetrators to form and use adaptive strategies as well as their abilities to manage or inhibit affective arousal to violence.
Head injury in partner-abusive men
Journal of Consulting and Clinical Psychology, 1994
Research into etiology of marital aggression has focused primarily on psychosocial, political, and cultural factors, to the exclusion of physiological influences. Fifty-three partner abusive men, 45 maritally satisfied, and 32 maritally discordant, nonviolent men were evaluated for past history of head injury, by a physician who was not informed of group membership and aggression history. Logistic regressions confirmed that head injury was a significant predictor of being a batterer. The implications of these findings for both marital aggression and post-head injury rehabilitation are discussed.

It is important to understand the epidemiology of intimate partner violence (IPV) experienced by both males and females. Data were drawn from the U.S. National Comorbidity Survey Replication. The relationships between physical IPV and child abuse, mental disorders, and suicidal ideation and attempts among males and females were examined. The results indicate that child sexual abuse was associated with IPV among males, whereas child physical and sexual abuse was associated with IPV among females. IPV was associated with poor mental health outcomes for males and females, although sex differences are noted. The sex differences indicate that females experience a wider range of poor mental health outcomes compared to males. Knowledge about correlates of IPV can be useful in identifying individuals exposed to violence. Further research is required to identify effective methods to reduce exposure to IPV and to adequately address the specific needs of male and female victims of IPV.

The number of women in the United States that experience blows to the head during assaults by intimate partners is substantial. The number of head blows that result in a traumatic brain injury (TBI) is virtually unknown, but estimates far exceed numbers of TBI in parallel populations (e.g., blast exposure, accidents, sports) combined. Research on the impact of TBI on post-traumatic stress disorder (PTSD) in survivors of intimate partner violence (IPV) is sparse. This methodology paper describes the comprehensive, multi-method approach used by a multi-disciplinary team of investigators from several different fields of expertise to assess the interaction of psychiatric, cognitive, psychological, and physical conditions that result from IPV. Using state-of-the-art instruments, a comprehensive assessment of lifetime trauma exposure, lifetime history of TBI, psychiatric history, and a full assessment of current cognitive, neuropsychological and biomedical function was conducted with 51 f...
Intimate partner violence includes psychological aggression, physical violence, sexual violence, and stalking from a current or former intimate partner. Experiencing intimate partner violence is associated with impaired neurocognitive and psychosocial functioning, mental illness, as well as structural brain alterations. These impairments seem to be compounded by exposure to physical trauma to the head. Importantly, up to 90% of women exposed to intimate partner violence also experience some form of head trauma or even repetitive head trauma. However, research on this topic is sparse, and the neurobehavioral and neurobiological effects of head trauma in this population have not been systematically investigated. A key aim of the Enhancing Neuroimaging and Genetics through Meta-Analysis Consortium Intimate Partner Violence Working Group is to provide recommendations for the harmonization of measures collected to facilitate the meta-analysis of neuropsychological, neuroimaging, and gene...
Mental health of perpetrators of intimate partner violence
Mental Health Review Journal
PurposeIntimate partner violence (IPV) represents a widespread social and public health problem. Researchers have been shown association between IPV and mental health problems. The purpose of this paper is to present a review of the literature on relationship between wide ranges of mental health problems.Design/methodology/approachResearch papers related to mental health problems among IPV perpetrators and published in leading academic journals in UK and abroad from 1987 to 2017 were identified and reviewed.FindingsAlthough there were some equivocal findings, the authors found that most of the available research suggests that there is a variety of psychological health problems among IPV perpetrators. Specifically, there was evidence of a significant relationship between anger problems, anxiety, depression, suicidal behaviour, personality disorders, alcoholism or problem gambling and perpetration of IPV. Results from analysed studies identified high rates of co-morbid disorders in IP...
The neuropathology of intimate partner violence
Acta Neuropathologica
Lifelong brain health consequences of traumatic brain injury (TBI) include the risk of neurodegenerative disease. Up to one-third of women experience intimate partner violence (IPV) in their lifetime, often with TBI, yet remarkably little is known about the range of autopsy neuropathologies encountered in IPV. We report a prospectively accrued case series from a single institution, the New York City Office of Chief Medical Examiner, evaluated in partnership with the Brain Injury Research Center of Mount Sinai, using a multimodal protocol comprising clinical history review, ex vivo imaging in a small subset, and comprehensive neuropathological assessment by established consensus protocols. Fourteen brains were obtained over 2 years from women with documented IPV (aged 3rd–8th decade; median, 4th) and complex histories including prior TBI in 6, nonfatal strangulation in 4, cerebrovascular, neurological, and/or psychiatric conditions in 13, and epilepsy in 7. At autopsy, all had TBI st...
