Childhood family violence and perpetration and victimization of intimate partner violence: findings from a national population-based study of couples

Maltreatment in childhood and intimate partner violence: A latent class growth analysis in a South African pregnancy cohort

Intimate partner violence (IPV) is a significant global problem, prevalent in low and middle-income countries (LMICs). IPV is particularly problematic during the perinatal and early postnatal period, where it is linked with negative maternal and child health outcomes. There has been little examination of profiles of IPV and early life adversity in LMIC contexts. We aimed to characterize longitudinal IPV and to investigate maternal maltreatment in childhood as a predictor of IPV exposure during pregnancy and postnatally in a low resource setting. This study was nested in the Drakenstein Child Health Study, a longitudinal birth cohort. Maternal IPV (emotional, physical and sexual) was measured at six timepoints from pregnancy to two years postpartum (n = 832); sociodemographic variables and maternal maltreatment in childhood were measured antenatally at 28-32 weeks' gestation. Associations between maternal maltreatment in childhood and IPV latent class membership (to identify patterns of maternal IPV exposure) were estimated using multinomial and logistic regression. We observed high levels of maternal maltreatment during childhood (34%) and IPV during pregnancy (33%). In latent class analysis separating by IPV sub-type, two latent classes of no/low and moderate sexual IPV and three classes of low, moderate, and high emotional and physical IPV (separately) were detected. In combined latent class analysis, including all IPV sub-types together, a low, moderate and high exposure class emerged as well as a high antenatal/decreasing postnatal class. Moderate and high classes for all IPV sub-types and combined analysis showed stable intensity profiles. Maternal childhood sexual abuse, physical abuse and neglect, and emotional abuse predicted membership in high IPV classes, across all domains of IPV (aORs between 1.99 and 5.86). Maternal maltreatment in childhood was associated with increased probability of experiencing high or moderate intensity IPV during and around pregnancy; emotional neglect was associated with decreasing IPV class for combined model. Intervening early to disrupt this cycle of abuse is critical to two generations.

Witnessing intimate partner violence as a child: How boys and girls model their parents' behaviors in adolescence

Childhood witnesses of adult violence at home are at risk for future violence. It is unclear how gender of the child and adult perpetrator are related to adolescent relationship violence. We explore how childhood witnessing of same-gender, opposite-gender, and bidirectional violence perpetrated by adults is associated with adolescent relationship violence victimization only, perpetration only, and combined victimization/perpetration for male and female undergraduates. We gathered cross-sectional data from 907 undergraduates attending 67 randomly-selected classes at three distinct East-Coast colleges using pencil-and-paper surveys administered at the end of class time. Multiple imputation with chained equations was used to impute missing data. Multinomial regression models controlling for gender, age, race, school, and community violence predicted adolescent outcomes for each witnessing exposure; relative risk ratios and average adjusted probabilities with 95% confidence intervals are presented. Adolescent relationship violence outcomes vary based on gender of the child witness and adult perpetrator. Witnessing adult males perpetrate is associated with higher perpetration for boys and higher combined victimization/perpetration for girls. Witnessing adult females perpetrate - either as the sole perpetrator or in a mutually violent relationship with an adult male - increases risk for combined victimization/perpetration for boys and girls during adolescence.

Adverse Childhood Experiences and Mental and Behavioral Health Conditions During Pregnancy: The Role of Resilience

INTRODUCTION

Little is known about how exposure to adverse childhood experiences (ACEs) and protective factors, such as resilience, influence prenatal mental and behavioral health. This study examined associations between exposure to ACEs and mental and behavioral health during pregnancy overall and among women with high versus low levels of resilience.

MATERIALS AND METHODS

Women in two Kaiser Permanente Northern California medical centers were screened for ACEs and resilience during prenatal care (∼14-23 weeks of gestation; N = 355). Multivariable logistic regression analyses examined associations between ACEs and prenatal mental and behavioral health conditions overall and for women with low (≤32) versus high (>32) resilience on the 10-item Connor-Davidson Resilience Scale.

RESULTS

Overall, 54% of women reported 0 ACEs, 28% 1-2 ACEs, and 18% 3+ ACEs. Relative to women with 0 ACEs, those with 1-2 ACEs had higher odds of an anxiety or depressive disorder and intimate partner violence (IPV) (odds ratios [ORs] 2.42-3.12, p < 0.05), and those with 3+ ACEs had higher odds of an anxiety or depressive disorder, depression symptoms, and IPV (ORs 3.08-4.71, p < 0.05). In stratified analyses by high (56%) and low (44%) resilience, having one or more ACEs (vs. 0 ACEs) was only associated with worse mental and behavioral health in women with low resilience.

CONCLUSIONS

ACEs predicted mental and behavioral health conditions among pregnant women, and associations were the strongest among women with low levels of current resilience. Longitudinal research is needed to understand the causal mechanisms underlying these associations.

Reflections of Men of Mexican Origin: A Grounded Theory Study of Intimate Partner Violence Risk Factors

Intimate partner violence (IPV) is a societal problem with many repercussions for the health care and judicial systems. In the United States, women of color are frequently affected by IPV and experience negative, physical, and mental ramifications. Increasing IPV perpetration and perpetration recurrence rates among men of Mexican origin (MMO) warrants a better understanding of unique risk factors that can only be described by these men. Qualitative studies regarding MMO and distinct IPV risk factors among this populace are few and infrequent. The purpose of this study was to describe IPV risk factors among men of MMO and to describe the process by which these men are able to overcome IPV perpetration risk factors. Fifty-six men of Mexican origin from a low-income housing community in far-west Texas were recruited for participation in audiotaped focus groups. Grounded theory (GT) methodology techniques were utilized to analyze, translate, and transcribe focus group data. Data collection ended when saturation occurred. Participants described risk factors for IPV. Emerging themes included: environment as a context, societal view of MMO, family of origin, normalcy, male and female contributing factors to IPV, and breaking through. Theme abstractions led to the midrange theory of Change Through Inspired Self-Reflection which describes the process of how MMO move from IPV perpetration to nonviolence. The results of the study provide insight on what MMO believe are IPV risk factors. There are implications for clinicians who provide services to MMO, and provide the impetus for future research among this population.

A Cumulative Risk Model of Child Physical Maltreatment Potential: Findings From a Community-Based Study

Previous studies have identified the predictive risk factors of child physical maltreatment (CPM). However, a significant number of these studies assessed risk factors in isolation. The cumulative risk hypothesis postulates that health problems are caused by the accumulation of risk factors, independently of the presence or absence of specific risk indicators. Few studies examined the effect of cumulative risk on CPM potential. This study aimed to test two concurrent models of cumulative risk of CPM potential by investigating whether CPM potential was better predicted by a threshold cumulative risk model or a linear cumulative risk model. Data from the National Representative Study of Psychosocial Context of Child Abuse and Neglect in Portugal were used. Parents of school-age children ( N = 796) answered to self-report measures regarding sociodemographic variables, history of child maltreatment, psychological distress, and CPM potential. A cumulative risk index was computed, comprising 10 dichotomized risk factors. Evidence for a threshold cumulative effect was found. Additional bivariate logistic regressions revealed that the odds for high-potential CPM were dramatically higher for those parents with six or more risk factors when compared with parents with any one risk factor. By testing and confirming a threshold cumulative effect on CPM potential, it was possible to find a "trigger point" from which a dramatic increase in child physical maltreatment potential occurs.

Risk Factors for Domestic Violence in Women and Predictors of Development of Mental Disorders in These Women

INTRODUCTION

Based on the hypothesis that women who exposed to physical violence had lower education and income levels than those who did not, and those who got married earlier and had marriage with unwanted people had higher psychiatric disorders, the aims of this study were to determine risk factors for domestic violence and predictors of psychiatric impairment in women exposed to domestic violence.

METHODS

We used random selection method and included 400 married women above 18 years of age living in Adiyaman province. Socio-demographic data and exposure to physical violence and sexual coercion for participants were evaluated by a structured questionnaire. Depression scores of the women were evaluated by Beck Depression Inventory (BDI) and anxiety scores were evaluated by Beck Anxiety Inventory (BAI). Suicidal ideas of the subjects were evaluated by 17 item Suicide Intent Scale and their suicide plans, attempts, thoughts, and risk of recurrence were evaluated by 4 item Suicidal Behavior Questionnaire.

RESULTS

65,5% of the women (n=262) reported no violence, 19,3% (n=77) reported violence only from their spouses, 5,2% (n=21) reported violence from people other than spouse, and 10% (n=40) reported physical violence from both their spouses and other people. Logistic regression analysis showed that employment status of spouses, presence of medical/psychiatric illness in spouses, the acceptance of the view that 'Husbands can sometimes beat' by women and presence of psychiatric illness in women predicted domestic violence against these women from their spouses. Logistic regression analysis also revealed that education level, and presence of physical or sexual violence from their spouses predicted development of psychiatric disorders in women survivors of domestic violence.

CONCLUSION

This study showed that opinion of women about domestic violence, presence of a psychiatric disorder in women, employment status of spouse, and presence of a medical/psychiatric illness in spouse predicted physical violence against these women. In addition, education level of women, and presence of domestic violence from their spouses predicted development of psychiatric disorder. Knowing the factors that trigger physical violence and related psychiatric impairments is really important for development of preventive and therapeutic interventions.

The association between child exposure to intimate partner violence (IPV) and perpetration of IPV in adulthood-A systematic review

Increasingly recognized as a distinct form of childhood maltreatment, children's exposure to intimate partner violence (IPV) has been shown to be associated with an array of negative psychosocial outcomes, including elevated risk for additional violence over the life course. Although studies have identified child exposure to IPV as a predictor of IPV perpetration in adulthood, no review has critically evaluated the methodology of this quantitative work. The present study examines the association between childhood exposure to IPV and the perpetration of IPV in adulthood based on a systematic review of the literature from inception to January 4, 2016. Databases searched included Medline, Embase, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews, Sociological Abstracts and ERIC. Database searches were complemented with backward and forward citation chaining. Studies were critically appraised using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Of 5601 articles identified by the search, 19 studies were included for data extraction. Sixteen of these studies found that child exposure to IPV was significantly and positively associated with adult IPV perpetration; three studies reported null findings. The methodological quality of the studies was low. Work thus far has tended to focus on child exposure to physical IPV and the perpetration of physical IPV within heterosexual contexts. In addition, measures of child exposure to IPV vary in their classification of what exposure entails. We critically discuss the strengths and limitations of the existing evidence and the theoretical frameworks informing this work.

Alcohol Intoxication Moderates the Association between a Polygenic Risk Score and Unprovoked Intimate Partner Aggression

Despite evidence that genetic variation contributes to aggression, few studies have examined how genetic variation contributes to IPA specifically. In the current study, 69 couples from a Midwestern university completed self-report measures of IPA, childhood trauma exposure, and hazardous alcohol use, and were randomly assigned to consume either a placebo or alcohol beverage before participating in an analogue aggression task against their partner. Genetic risk (i.e., association with lower transcriptional efficiency) for aggression was measured with a polygenic risk score (PRS) created from four polymorphisms (HTR1B rs13212041, HTR2B rs6437000, 5-HTTLPR, and MAOA uVNTR). Among individuals with a low PRS, individuals who consumed alcohol (BrAC = 0.07%) showed greater unprovoked IPA than individuals who consumed a placebo. Findings contribute to our limited understanding regarding the etiology of IPA and suggest that individuals who have increased transcriptional activity in certain serotonin system genes may be at higher risk of IPA when intoxicated.

Prevalence and Characteristics of Interpersonal Violence in People Dying From Suicide in Victoria, Australia

Victims of interpersonal violence are known to be at increased risk of suicidal ideation and attempts; however, few data exist on the impact that violence has on the risk of death from suicide. This study examined 2153 suicides (1636 males and 517 females) occurring between 2009 and 2012. Information was sourced from the Coroners Court of Victoria’s Suicide Register, a detailed database containing information on all Victorian suicides. Forty-two percent of women who died from suicide had a history of exposure to interpersonal violence, with 23% having been a victim of physical violence, 18% suffering psychological violence, and 16% experiencing sexual abuse. A large number of men who died from suicide had also been exposed to interpersonal violence, many of whom had perpetrated violence within the 6 weeks prior to their death. Targeted prevention, particularly removing barriers for men to seek help early after perpetrating violence is likely to have benefits in preventing suicide in both men and women.

Childhood physical and sexual abuse experiences associated with post-traumatic stress disorder among pregnant women

PURPOSE

We sought to evaluate the extent to which childhood physical and/or sexual abuse history is associated with post-traumatic stress disorder (PTSD) during early pregnancy and to explore the extent to which the childhood abuse-PTSD association is mediated through, or modified by, adult experiences of intimate partner violence (IPV).

METHODS

In-person interviews collected information regarding history of childhood abuse and IPV from 2,928 women aged 18-49 years old prior to 16 weeks of gestation. PTSD was assessed using the PTSD Checklist-Civilian Version. Multivariate logistic regressions were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

Compared to women with no childhood abuse, the odds of PTSD were increased 4.31-fold for those who reported physical abuse only (95% CI, 2.18-8.49), 5.33-fold for sexual abuse only (95% CI, 2.38-11.98), and 8.03-fold for those who reported physical and sexual abuse (95% CI, 4.10-15.74). Mediation analysis showed 13% of the childhood abuse-PTSD association was mediated by IPV. Furthermore, high odds of PTSD were noted among women with histories of childhood abuse and IPV compared with women who were not exposed to either (OR = 20.20; 95% CI, 8.18-49.85).

CONCLUSIONS

Childhood abuse is associated with increased odds of PTSD during early pregnancy. The odds of PTSD were particularly elevated among women with a history of childhood abuse and IPV. Efforts should be made to prevent childhood abuse and mitigate its effects on women's mental health.

The impact of perceived childhood victimization and patriarchal gender ideology on intimate partner violence (IPV) victimization among Korean immigrant women in the USA

Childhood victimization experiences are common among intimate partner violence (IPV) victims. This study examines the link between childhood physical and sexual victimization experiences and adulthood IPV among Korean immigrant women in the USA. As Korean immigrants often use physical punishment to discipline their children, and reporting sexual abuse is discouraged due to stigmatization in this community, cultural factors (e.g. patriarchal values) related to childhood victimization and IPV were also examined. Survey data from Korean immigrant women in the USA were collected. Using a case-control design, we compared 64 Korean immigrant women who have experienced IPV in the past year with 63 Korean immigrant women who have never experienced IPV in their lifetime. The findings of this study reveal that IPV victims, compared with non-victims, experienced higher childhood victimization rates. Logistic regression analysis demonstrated that childhood victimization and patriarchal gender ideology strongly predict IPV victimization among Korean immigrants. However, patriarchal values did not moderate the relationship between childhood victimization and IPV. To prevent IPV among Korean immigrant population, we need to make special efforts to prevent childhood abuse and change ingrained cultural attitudes about child physical and sexual abuse among immigrant communities through culturally sensitive programs.

Risk Factors for Hispanic Male Intimate Partner Violence Perpetration

The literature review analyzed 24 studies that explored male intimate partner violence (IPV) perpetration risk factors among men, in particular Hispanics, using the socioecological model framework composed of four socioecological levels for violence prevention. Six databases were reviewed within the EBSCO search engine for articles published from 2000 to 2014. Articles reviewed were specific to risk factors for IPV perpetration among Hispanic men, focusing particularly on Mexican American men. Many key factors have previously been associated with risk for IPV perpetration; however, certain determinants are unique to Hispanics such as acculturation, acculturation stress, and delineated gender roles that include Machismo and Marianismo. These risk factors should be incorporated in future targeted prevention strategies and efforts and capitalize on the positive aspects of each to serve as protective factors.

Exploring the Association of Maternal Adverse Childhood Experiences with Maternal Health and Child Behavior Following Intimate Partner Violence

BACKGROUND

Adverse childhood experiences (ACEs) have been empirically linked to a host of negative health outcomes, both physical and psychosocial. Exposures to ACEs make individuals more susceptible to conditions such as cardiovascular disease, diabetes, cancers, and depression. Many of these conditions do not appear until sometime in adolescence or adulthood and have been linked to premature death.

OBJECTIVE

This study explores the association between the number and type of exposure to ACEs in women (mothers) who experienced intimate partner violence and health outcomes. Specifically, it explores the association between maternal ACEs and maternal perceived health and maternal mental and behavioral health. This study also explores the association between ACEs and child behavior.

METHODS

This analysis is part of a 7-year prospective study. A cohort of 300 mother-child pairs was assessed at baseline and every 4 months after reaching out for shelter or justice services for the very first time after being in an abusive intimate relationship.

RESULTS

Data document individual mothers' ACE scores and show a trend at 12 months, 24 months, and is most significant at 36 months. Additionally, at 36 months, higher ACE scores were significantly associated with all child behavioral subscales (anxiety, depression, aggressive behavior, attention problems, internalizing, externalizing).

CONCLUSION

The women in this study reported ACE scores consistently higher than national rates. Our data highlight the added benefit of using ACE criteria as a global prevention strategy to identify those most at risk for delayed mental and behavioral health issues and to intervene with supportive strategies and guided referrals as indicated.

Childhood Sexual Abuse and Sociodemographic Factors Prospectively Associated with Intimate Partner Violence Perpetration Among South African Heterosexual Men

BACKGROUND

Intimate partner violence directed at women by men continues to be a global concern. However, little is known about the factors associated with perpetrating intimate partner violence among heterosexual men.

PURPOSE

History of childhood sexual abuse and other sociodemographic variables were examined as potential factors associated with severe intimate partner violence perpetration toward women in a sample of heterosexual men in South Africa.

METHODS

Longitudinal logistic generalized estimating equations examined associations of childhood sexual abuse and sociodemographic variables at baseline with intimate partner violence perpetration at subsequent time points.

RESULTS

Among participants with a steady female partner, 21.81 % (190/ 871) reported perpetrating intimate partner violence in the past year at baseline. Having a history of childhood sexual abuse (p < .001), binge drinking (p = .002), being employed (p = .050), and more difficulty controlling sexual impulses in order to use a condom (p = .006) at baseline were associated with self-reported intimate partner violence perpetration in the past year at subsequent time points.

CONCLUSIONS

With high levels of recent severe physical and/or sexual intimate partner violence perpetration in South Africa, comprehensive interventions are urgently needed. To more fully address gender-based violence, it is important to address associated factors, including exposure to childhood sexual abuse that could impact behavior later in life and that have long-lasting and deleterious effects on men and their female partners.

Exposing the culture of silence: Inhibiting factors in the prevention, treatment, and mitigation of sexual abuse in the Eastern Caribbean

This article features a study that explored the presence of adverse childhood experiences (ACEs), including childhood sexual abuse and neglect, among women associated with Partnership for Peace (PfP), the first and only culturally adapted domestic violence diversion program for men in the Eastern Caribbean. Within a multiyear evaluative study that assessed the impact of the PfP intervention in reducing domestic violence in Grenada in the West Indies, life-history interviews were collected from a subsample of women (N=9) associated with men enrolled in the PfP program between 2009 and 2011. We found that the exposure to sexual abuse and neglect during childhood was evident in the histories of the women. Most perpetrators were trusted family or community members who suffered from a common set of behavioral patterns, most prominently alcohol use. Our findings reflect an evidence-based connection, as one causative factor, of a culture of silence that is related to child sexual abuse and its management. The apparent lasting effects of these traumatic childhood exposures reflect cycles of abuse in the life histories collected during the domestic violence evaluation study. Our study identified three key structural deficiencies (insufficient research, ineffective policy, and lack of public-health interventions) and one embedded cultural norm (the culture of silence) that together "inhibit current attempts to address ACEs as a means of curbing domestic violence in the Caribbean."

Strengthening Positive Parenting in the Context of Intimate Partner Abuse

Intimate partner violence has been associated with long-term negative effects on mothers' mental health status, use of positive parenting practices, and their children's externalizing behavioral difficulties. Especially strong is the association between concurrent experiences of partner violence and maternal parenting. In this case study, we examined the impact of behavioral parent training on parenting and outcomes for a 6-year-old Latino diagnosed with oppositional defiant disorder (ODD). The family was participating in a larger study examining the implementation and cultural adaptations of an evidence-based parent training program, Helping the Noncompliant Child. Mother reported a history of domestic violence and ongoing abusive behavior from her intimate partner but only wanted services focused on addressing child's behavioral difficulties and improving the quality of parent-child interactions. Adaptations included but were not limited to the translation of all intervention materials, extending the number of sessions focused on each parenting strategy, flexibility with regard to the location and time of therapy sessions, negotiating safe times for the family to participate in treatment, and case management. Parent reports of child behavior and parenting stress moved from the clinical range to the normal range from pre- to post-test. Mother also reported increased use of positive parenting practices. These data, along with closing semi-structured interviews, suggest that within the context of ongoing partner abuse, a mother's parenting and her child's behavior can be positively affected by parent training that is adapted and responsive to the context of their family's situation.

Attitudes towards Intimate Partner Violence against Women among Women and Men in 39 Low- and Middle-Income Countries

BACKGROUND

Violence against women perpetrated by an intimate partner (IPV) is prevalent in low- and middle-income countries (LAMIC). The aim was to describe the attitudes of women and men towards perpetration of physical violence to women by an intimate partner, in a large group of low- and middle-income countries.

METHODS AND FINDINGS

We used data from Round Four of the UNICEF Multiple Indicator Cluster Surveys. Attitudes towards IPV against women were assessed by a study-specific scale asking if 'wife beating' is justified in any of five circumstances. Overall, data from 39 countries (all had data from women and 13 countries also had data from men) were included in the analyses. The proportions of women who held attitudes that 'wife-beating' was justified in any of the five circumstances varied widely among countries from 2.0% (95% CI 1.7;2.3) in Argentina to 90.2% (95% CI 88.9;91.5) in Afghanistan. Similarly, among men it varied from 5.0% (95% CI 4.0;6.0) in Belarus to 74.5% (95% CI 72.5;76.4) in the Central African Republic. The belief that 'wife-beating' is acceptable was most common in Africa and South Asia, and least common in Central and Eastern Europe and Latin America and the Caribbean. In general this belief was more common among people in disadvantaged circumstances, including being a member of a family in the lowest household wealth quintile, living in a rural area and having limited formal education. Young adults were more likely to accept physical abuse by a man of his intimate partner than those who were older, but people who had never partnered were less likely to have these attitudes.

CONCLUSIONS

Violence against women is an international priority and requires a multicomponent response. These data provide evidence that strategies should include major public education programs to change attitudes about the acceptability of IPV against women, and that these should be addressed to women and girls as well as to boys and men.

Military/Civilian Risk Markers for Physical Intimate Partner Violence: A Meta-Analysis

This meta-analysis compared risk markers for perpetration of physical intimate partner violence (IPV) among military and civilian males. We also examined strength of risk markers among male and female service members. In total, 36 military studies and 334 civilian studies, which reported 883 effect sizes, were included in the analyses. Results revealed more similarities than differences in risk markers for IPV among military and civilian males and among military males and females. Of the risk markers examined, relationship satisfaction and alcohol problems were significantly stronger risk markers for IPV among civilian males compared to military males. Perpetrating emotional abuse was a significantly stronger risk marker for IPV perpetration among military females compared to military males. Recommendations for IPV prevention and intervention are discussed.

Acceptability of Partner Violence in 51 Societies: The Role of Sexism and Attitudes Toward Violence in Social Relationships

Sexist attitudes have been claimed to play an important role in acceptability of intimate partner violence (IPV). Empirical evidence suggests that sexist individuals are also more accepting of violence in social relationships than non-sexist individuals. Results from multilevel regression models of data from 72,730 respondents of 51 countries around the world showed that (a) both sexism and acceptability of general violence in social relationships were positively related to acceptability of IPV and (b) the highest levels of acceptability of IPV were found among those sexist individuals who also present positive attitudes toward the use of violence in social relationships.

The Cycle of Violence Revisited: Distinguishing Intimate Partner Violence Offenders Only, Victims Only, and Victim-Offenders

Using a cycle of violence framework, we investigated experiences with physical intimate partner violence (IPV) victimization, perpetration, and both IPV victimization and perpetration (IPV overlap). Data included the U.S. subsample of college students in the International Dating Violence Study (n = 4,162). Findings indicated that 40% of participants reported lifetime IPV, with 28% reporting membership in the overlap group. Cycle of violence variables including child sexual abuse, witnessing violence inside the home during childhood, and witnessing violence outside the home during childhood were uniquely related to membership in the overlap group. No relationship between cycle of violence variables and IPV victimization only or IPV perpetration only was identified. Results suggested the cycle of violence might predominantly operate among individuals who are both IPV victims and offenders, rather than among individuals experiencing IPV victimization or perpetrate IPV exclusively.

DSM-5 Pathological Personality Traits and Intimate Partner Violence Among Male and Female College Students

The purpose of this study was to examine associations between pathological personality traits identified in the Diagnostic and Statistical Manual of Mental Disorders (5th ed., DSM-5) Section III alternative model of personality disorder (using the Personality Inventory for DSM-5; PID-5) and intimate partner violence (IPV; using the Conflict Tactics Scale [CTS]) in a sample of male (N = 1,106) and female (N = 1,338) college students. In this sample, self and partner perpetration of CTS Relationship Violence and CTS Negotiation tactics loaded onto 2 separate factors. The PID-5 facets and domains were differentially associated with these factors for both men and women. Facets and domains explained 10.1%-16.1% and 5.8%-10.6% of the variance in CTS Relationship Violence tactics, respectively. For both genders, detachment was positively associated with relationship violence. Antagonism was uniquely associated with relationship violence for women, whereas disinhibition was uniquely associated with relationship violence for men. Associations with lower level pathological personality facets were also examined. Overall, results indicate that DSM-5 pathological personality traits are associated with IPV reported by both men and women.

Sexual risk, substance use, mental health, and trauma experiences of gang-involved homeless youth

This study examined the associations of sexual risk behaviors, substance use, mental health, and trauma with varying levels of gang involvement in a sample of Los Angeles-based homeless youths. Data were collected from 505 homeless youths who self-reported various health information and whether they have ever identified as or been closely affiliated with a gang member. Multivariable logistic regression assessed associations of lifetime gang involvement with risk taking behaviors and negative health outcomes. Results revealed seventeen percent of youths have ever identified as a gang member and 46% as gang affiliated. Both gang members and affiliates were at greater risk of many negative behaviors than non-gang involved youths. Gang members and affiliates were more likely to report recent methamphetamine use, cocaine use, chronic marijuana use, having sex while intoxicated, and symptoms of depression, symptoms of posttraumatic stress disorder. They were also more likely to have experienced childhood sexual abuse and witnessing family violence. Gang members were more likely to ever attempt suicide, experience recent partner violence, and report physical abuse during childhood. Results suggest that lifetime gang involvement is related to a trajectory of negative outcomes and amplified risk for youths experiencing homelessness. Additionally, being closely connected to a gang member appears to have just as much as an impact on risk as personally identifying as a gang member. Given the lack of knowledge regarding the intersection between youth homelessness and gang involvement, future research is needed to inform policies and programs that can address the specific needs of this population.

Exploring revictimization process among Turkish women: The role of early maladaptive schemas on the link between child abuse and partner violence

The purpose of the current study is to explore the revictimization process between child abuse and neglect (CAN), and intimate partner violence (IPV) based on the schema theory perspective. For this aim, 222 married women recruited in four central cities of Turkey participated in the study. Results indicated that early negative CAN experiences increased the risk of being exposed to later IPV. Specifically, emotional abuse and sexual abuse in the childhood predicted the four subtypes of IPV, which are physical, psychological, and sexual violence, and injury, while physical abuse only associated with physical violence. To explore the mediational role of early maladaptive schemas (EMSs) on this association, first, five schema domains were tested via Parallel Multiple Mediation Model. Results indicated that only Disconnection/Rejection (D/R) schema domains mediated the association between CAN and IPV. Second, to determine the particular mediational roles of each schema, eighteen EMS were tested as mediators, and results showed that Emotional Deprivation Schema and Vulnerability to Harm or Illness Schema mediated the association between CAN and IPV. These findings provided an empirical support for the crucial roles of EMSs on the effect of revictimization process. Clinical implications were discussed.

Modeling the intergenerational impact of partner abuse on maternal and child function at 24 months post outreach: Implications for practice and policy

OBJECTIVE

Many women are exposed to partner violence during their lifetime which affects mental health and child development. This study revalidates an intergenerational model connecting partner violence to poor functioning for mothers and children using structural equation techniques.

METHOD

A longitudinal design collected data on 300 mother-child pairs. Comparisons between the model, tested at study entry and again at 24 months, are reported. Maternal measures included childhood experiences of abuse, partner abuse, chronic pain, and mental health. The Child Behavior Checklist measured child function.

RESULTS

Comparison of both models revealed that maternal chronic pain, maternal mental health, and child witnessing of mother's abuse remain strong predictors of child dysfunction. Maternal social support and self-efficacy are significant predictors of more positive maternal mental health with a conduit effect on child behavior.

CONCLUSION

Intimate partner violence directly impacts the victim and also has a secondary impact on the children of abuse victims.

Assessing the family dynamics of childhood maltreatment history with the Childhood Attachment and Relational Trauma Screen (CARTS)

BACKGROUND

Existing survey measures of childhood trauma history generally fail to take into account the relational-socioecological environment in which childhood maltreatment occurs. Variables such as the relationship between the perpetrator and the victim, the emotional availability of caregivers, witnessing the abuse of others, and the respondent's own thoughts, feelings, and actions in response to maltreatment are rarely assessed by current measures.

METHODS

To address these concerns, the current study further investigated the family dynamics of childhood maltreatment using the Childhood Attachment and Relational Trauma Screen (CARTS) in 1,782 persons assessed online.

RESULTS

Paired differences in means between item-rated descriptiveness of self, mothers, and fathers suggested that respondents' relationship with their biological fathers was less positive and secure than their relationship with their biological mothers, and that biological fathers were more often the perpetrator of emotional, physical, and sexual abuse than biological mothers. However, results further suggested that ratings between self, mothers, and fathers were positively correlated such that, for example, reports of a mother's or a respondent's own abusive behavior were more likely in the presence of reports of a father's abusive behavior. In addition, analyses evaluating witnessing violence demonstrated that fathers were rated as more often violent toward mothers than the reverse, although intimate partner violence was also frequently bidirectional. Analyses of sibling ratings further demonstrated that older brothers were either as or more frequently abusive when compared with parents. Finally, results suggested that childhood emotional, physical, and sexual abuse were much more often perpetrated by family members than extra-familial and non-family members.

CONCLUSIONS

In so far as these findings are consistent with the prior childhood trauma and attachment literature, the current study further supports the utility of the CARTS as a means of assessing the family dynamics of childhood attachment and maltreatment within a relational-socioecological framework.

Stress and the social brain: behavioural effects and neurobiological mechanisms

Stress often affects our social lives. When undergoing high-level or persistent stress, individuals frequently retract from social interactions and become irritable and hostile. Predisposition to antisocial behaviours - including social detachment and violence - is also modulated by early life adversity; however, the effects of early life stress depend on the timing of exposure and genetic factors. Research in animals and humans has revealed some of the structural, functional and molecular changes in the brain that underlie the effects of stress on social behaviour. Findings in this emerging field will have implications both for the clinic and for society.

The interplay of trait anger, childhood physical abuse, and alcohol consumption in predicting intimate partner aggression

The current study examined three well-established risk factors for intimate partner aggression (IPA) within Finkel and Eckhardt's I(3) model, including two impellance factors-trait anger and childhood physical abuse history-and the disinhibiting factor of alcohol consumption. Participants were 236 male and female college students in a committed heterosexual dating relationship who completed a battery of self-report measures assessing childhood physical abuse, trait anger, alcohol consumption, and IPA perpetration. Results revealed a significant three-way interaction showing that as the disinhibition factor alcohol consumption increased, the interaction of the two impelling factors, trait anger and childhood physical abuse, became increasingly more positive. Individuals who had high levels of childhood physical abuse and alcohol consumption were at greater risk of IPA perpetration when trait anger was high. Consistent with the I(3) model, these findings suggest that trait anger and a history of childhood physical abuse may increase tendencies to aggress against one's partner, whereas alcohol consumption may reduce individuals' abilities to manage these aggressive tendencies. The importance of interplay among these risk factors in elevating IPA risk is discussed, as are the implications for clinicians working with male and female IPA perpetrators.

Adverse childhood experiences and intimate partner aggression in the US: sex differences and similarities in psychosocial mediation

Six in ten people in the general population have been exposed to adverse childhood experiences (ACEs). Intimate partner violence (IPV) is a major public health problem in the US. The main objective of this study was to assess sex differences in the role of posttraumatic stress disorder (PTSD), substance abuse, and depression as mediators in the association between ACEs and intimate partner aggression. Data were obtained from Wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Structural equation modeling was used to determine the mediational role of PTSD, substance abuse and depression in the association between ACE constructs (neglect, physical/psychological abuse, sexual abuse, parental violence, and parental incarceration/psychopathology) and intimate partner aggression. Among men, PTSD mediated the relationship between sexual abuse and intimate partner aggression. However, among men and women, substance abuse mediated the relationship between physical and psychological abuse and intimate partner aggression. IPV programs geared towards aggressors should address abuse (sexual, physical and psychological), which occurred during childhood and recent substance abuse and PTSD. These programs should be implemented for men and women. Programs aimed at preventing abuse of children may help to reduce rates of depression and PTSD in adulthood, and subsequent intimate partner aggression.

A cycle of violence? Examining family-of-origin violence, attitudes, and intimate partner violence perpetration

Exposure to violence in the family-of-origin has consistently been linked to intimate partner violence (IPV) perpetration in adulthood. However, whether the transmission of violence across generations is role- and gender-specific still remains unclear. The current study examined the effects of experiencing child abuse and observing parental violence on IPV perpetration among a sample of male arrestees (N = 303). The differential effects of observing violence perpetrated by same-sex (father to mother), opposite-sex (mother to father), and both parents on subsequent IPV perpetration were examined. Logistic regression analyses showed that while observing father-only violence and bidirectional interparental violence was predictive of IPV perpetration, observing mother-only violence and direct experiences of child abuse was not. These findings suggest that the transmission of violence across generations is both role- and gender-specific and highlight the importance of examining unique dimensions of partner violence to assess influences on children. The study further examined whether attitudes justifying wife beating mediate the effect of exposure to violence and subsequent IPV perpetration. Results showed that although attitudes were predictive of perpetration, these attitudes did not mediate the relationship.

Intimate partner violence victims as mothers: their messages and strategies for communicating with children to break the cycle of violence

Children whose mothers are victims of intimate partner violence (IPV) are at increased risk of adverse health and psychosocial consequences, including becoming victims or perpetrators of violence in their own relationships. This study aimed to understand the role mothers may play in preventing the perpetuation of violence in their children's lives. We performed semistructured interviews with 18 IPV victims who are mothers and were living at the Women's Center & Shelter of Greater Pittsburgh from July through November 2011. We sought to understand how they communicate with their children about IPV and relationships. These mothers described a desire to explain their IPV experience and offer advice about avoiding violence in relationships. As foundations for these discussions, they emphasized the importance of close relationships and open communication with their children. Although mothers are interested in talking about IPV and relationships and identify communication strategies for doing so, many have never discussed these topics with their children. These mothers need and want an intervention to help them learn how to communicate with their children to promote healthy relationships. Development of a program to facilitate communication between IPV victims and their children could create an important tool to empower mothers to break the cross-generational cycle of domestic violence.

The Intersection of Partner Violence and Adverse Childhood Experiences: Implications for Research and Clinical Practice

Violence against women continues to be a serious public health issue afflicting women worldwide. The intersection of Adverse Childhood Experiences (ACEs) and intimate partner violence is detrimental to a woman's well-being. This review aims to identify the types of ACEs reported by women who also report partner violence and the subsequent negative impact of this combination of experiences on the women's health. The evidence supports the cumulative effects of Adverse Childhood Experiences on women, particularly when coupled with experiences of intimate partner violence. Early interventions by providers have the potential to mitigate negative health outcomes of abused women and interrupt the intergenerational transmission of violence to their children.

On the pervasiveness of event-specific alcohol use, general substance use, and mental health problems as risk factors for intimate partner violence

The aim of this study was to evaluate the role of demographic, mental health, and substance use as risk factors for intimate partner violence (IPV). Data were derived from Wave II of the National Epidemiological Survey on Alcohol and Related Conditions (2004-2005). Eligible participants (N = 25,778) reported having an intimate partner 1 year before the survey. Clustered survey multivariate multinomial regression methods were used to assess risk factors for episodes of IPV. IPV victimization, perpetration, and both victims/perpetrators were assessed. Bivariate analyses indicated that African Americans, Hispanics, and women were more likely to be victims, perpetrators, or victim/perpetrators as compared with men and Whites. Multivariate analyses suggested that having a marijuana use disorder was strongly associated with IPV victimization (odds ratio [OR] = 2.61) and victim/perpetration (OR = 2.65). Post-traumatic stress disorder was consistently associated with all IPV typologies. Depression was associated with victimization (OR = 2.00) and IPV victim/perpetration (OR = 1.74). Antisocial Personality Disorder and Mania were both related to IPV perpetration (ORs = 2.53 and 2.32) and victim/perpetration (ORs = 3.15 and 2.31). Results also indicated that alcohol use during episodes of IPV is common (i.e., 35% of those who reported IPV also reported that alcohol was involved). Results indicate several substance- and mental health-related correlates of IPV. In addition, findings indicate that alcohol use by the victim and/or perpetrator is common during IPV events. Policy implications and directions for future research are discussed.

Evidence of increased STI/HIV-related risk behavior among male perpetrators of intimate partner violence in Guatemala: results from a national survey

Intimate partner violence (IPV) is a significant public health problem with a demonstrated link to increased sexually transmitted infection (STI)/HIV-related risk and vulnerability. While IPV is an important issue in Central America, the link to STI/HIV risk has not been explored in this region. In this study, the relationship between emotional and physical/sexual IPV and the STI/HIV-related risk behaviors of sex worker patronage and infidelity is assessed among male IPV perpetrators using data from a national survey conducted in 2009 in Guatemala (n = 4773 married/partnered men). Bivariate associations between background characteristics and emotional and physical IPV perpetration were explored. Logistic regression models were run to test associations between IPV for each sexual risk behavior. Perpetration of emotional and physical/sexual IPV was more common among married/partnered men who were older than 24, had more education, lived in urban areas, or were in common law versus married unions. Reports of past-year emotional IPV perpetration increased as wealth quintile increased. After adjusting for demographics and other characteristics, physical/sexual IPV perpetration was associated with past-year infidelity (AOR 1.9, 95% CI: 1.1-3.6). Lifetime emotional IPV (AOR 1.4, 95% CI: 1.1-1.7) and physical/sexual IPV 1.6 (95% CI 1.2-2.0) were positively associated with a history of sex worker patronage. Endorsement of traditional gender role norms showed a marginally positive association with past-year infidelity in the adjusted model (AOR 1.3, 95% CI 1.0-1.8). The study findings from Guatemala reinforce the growing evidence globally that male IPV perpetrators are more likely to engage in risky sexual behavior, including sex worker patronage and main partner infidelity. The concurrency of violence and increased STI/HIV risk may compound the health risks for female victims of IPV who also face injury and psychological trauma. Integration of prevention and screening of IPV and STI/HIV prevention services should be adopted in Guatemala and other similar contexts.

Child abuse and neglect and intimate partner violence victimization and perpetration: a prospective investigation

This paper describes the extent to which abused and neglected children report intimate partner violence (IPV) victimization and perpetration when followed up into middle adulthood. Using data from a prospective cohort design study, children (ages 0-11) with documented histories of physical and sexual abuse and/or neglect (n=497) were matched with children without such histories (n=395) and assessed in adulthood (Mage=39.5). Prevalence, number, and variety of four types of IPV (psychological abuse, physical violence, sexual violence, and injury) were measured. Over 80% of both groups - childhood abuse and neglect (CAN) and controls - reported some form of IPV victimization during the past year (most commonly psychological abuse) and about 75% of both groups reported perpetration of IPV toward their partner. Controlling for age, sex, and race, overall CAN [adjusted odds ratio (AOR)=1.60, 95% CI [1.03, 2.49]], physical abuse (AOR=2.52, 95% CI [1.17, 5.40]), and neglect (AOR=1.64, 95% CI [1.04, 2.59]) predicted increased risk for being victimized by a partner via physical injury. CAN and neglect also predicted being victimized by a greater number and variety of IPV acts. CAN and control groups did not differ in reports of perpetration of IPV, although neglect predicted greater likelihood of perpetrating physical injury to a partner, compared to controls. Abused/neglected females were more likely to report being injured by their partner, whereas maltreated males did not. This study found that child maltreatment increases risk for the most serious form of IPV involving physical injury. Increased attention should be paid to IPV (victimization and perpetration) in individuals with histories of neglect.

Adolescent experiences of violence and relation to violence perpetration beyond young adulthood among an urban sample of Black and African American males

The purpose of this study is to determine if experiences of physical violence during early and late adolescence (12-21 years) places urban Black males at increased risk for interpersonal violence perpetration beyond young adulthood (30 years and older). Participants of this cross-sectional study were Black and African American men (N = 455) between the ages of 30 and 65 years, recruited from four urban clinical sites in the Northeast. Multivariate logistic regression models were used to analyze the relation of adolescent experiences of violence to: (1) past 6 month street violence involvement and (2) past year intimate partner violence perpetration. Ten percent of the sample reported that they experienced adolescent victimization. Men reporting adolescent victimization were significantly more likely to report past 6-month street violence involvement (Adjusted Odds Ratio (AOR) = 3.2, 95 % CI = 1.7-6.3) and past 6 month intimate partner violence perpetration (AOR = 2.8, 95 % CI = 1.8-5.4) compared to men who did not report such victimization. Study findings suggest that in order to prevent adulthood perpetration of violence, more work is needed to address experiences of victimization among young Black males, particularly violence experienced during adolescence.

Exposure to the Lebanon War of 2006 and effects on alcohol use disorders: the moderating role of childhood maltreatment

BACKGROUND

Civilian populations now comprise the majority of casualties in modern warfare, but effects of war exposure on alcohol disorders in the general population are largely unexplored. Accumulating literature indicates that adverse experiences early in life sensitize individuals to increased alcohol problems after adult stressful experiences. However, child and adult stressful experiences can be correlated, limiting interpretation. We examine risk for alcohol disorders among Israelis after the 2006 Lebanon War, a fateful event outside the control of civilian individuals and uncorrelated with childhood experiences. Further, we test whether those with a history of maltreatment are at greater risk for an alcohol use disorder after war exposure compared to those without such a history.

METHODS

Adult household residents selected from the Israeli population register were assessed with a psychiatric structured interview; the analyzed sample included 1306 respondents. War measures included self-reported days in an exposed region.

RESULTS

Among those with a history of maltreatment, those in a war-exposed region for 30+ days had 5.3 times the odds of subsequent alcohol disorders compared to those exposed 0 days (95%C.I. 1.01-27.76), controlled for relevant confounders; the odds ratio for those without this history was 0.5 (95%C.I. 0.25-1.01); test for interaction: X(2)=5.28, df=1, P=0.02.

CONCLUSIONS

Experiencing a fateful stressor outside the control of study participants, civilian exposure to the 2006 Lebanon War, is associated with a heightened the risk of alcohol disorders among those with early adverse childhood experiences. Results suggest that early life experiences may sensitize individuals to adverse health responses later in life.

Anger-related dysregulation as a factor linking childhood physical abuse and interparental violence to intimate partner violence experiences

OBJECTIVE

Childhood family violence exposure is associated with increased risk for experiencing intimate partner violence (IPV) in adulthood, but the mechanisms underlying this relationship remain inadequately understood. Difficulties with emotion regulation may be one factor that helps to explain this relationship.

METHOD

Childhood physical abuse and interparental violence, as well as subsequent IPV experiences, were assessed in a large sample of young adults (N = 670). Several indicators of anger-related dysregulation were also assessed. Structural equation modeling was used to create a latent variable of anger-related dysregulation, which was examined as a potential mediator of the associations between childhood family violence exposure and IPV.

RESULTS

Childhood physical abuse and interparental violence were associated with greater physical, sexual, and emotional IPV victimization. Childhood physical abuse and interparental violence were also associated with anger-related dysregulation, which was positively associated with all three types of IPV experiences. Anger-related dysregulation fully mediated the association between witnessing interparental violence and physical IPV. Anger-related dysregulation partially mediated the association between witnessing interparental violence and psychological IPV and the associations of childhood physical abuse with all three forms of IPV. These associations were consistent across gender.

CONCLUSIONS

Interventions aimed at reducing IPV risk among survivors of childhood family violence may benefit from including techniques to target anger-related emotion regulation skills.

Associations and experiences observed for family and nonfamily forms of violent behavior in different relational contexts among Swedish men and women

The aim of this study was to examine how lifetime experiences of different types of violent behavior as well as violence by different kinds of perpetrators overlap, and to investigate the co-occurrence of experiences of violent behavior by kind of perpetrator. This was done among both sexes in both a random sample from a county population (women n = 1,168, men n = 2,924) and a clinical sample (women n = 2,439, men, n = 1,767) in Sweden. More than 1 kind of perpetrator was reported by 33%-37% of female and 22%-23% of male victims of some kind of violence, whereas 47%-48% of female and 29%-31% of male victims reported more than 1 kind of violence. The reporting of 2 or 3 kinds of perpetrators was associated with the reporting of experiences of more than 1 kind of violent behavior. Health care providers must be trained to recognize the overlap of violent victimization and help prevent further victimization of those who already have such experiences.

An expanded approach to batterer intervention programs incorporating neuroscience research

Batterer Intervention Programs have been critiqued for failing to incorporate treatment strategies that are supported by neurobiology research. This article reviews findings that have informed the treatment of disorders that are strongly represented among perpetrators of intimate violence, such as addiction, posttraumatic stress disorder, mood, anxiety, and personality disorders. The article argues for an expanded perspective that recognizes the relationships among childhood trauma, emotional regulation impairment, and intimate partner violence. Recommendations and ways to draw on emerging knowledge to invigorate existing programs are provided.

Expanding Resource Theory and Feminist-Informed Theory to Explain Intimate Partner Violence Perpetration by Court-Ordered Men

This study tested resource and feminist-informed theories to explain physical, sexual, psychological, and stalking intimate partner violence (IPV) perpetrated by court-mandated men. Data were obtained from 340 men arrested for physical assault of a partner before their court-ordered treatment. Using path analysis, findings provided partial support for each model. Ineffective arguing and substance-use problems were moderators of resources and perpetration. Dominance mediated early exposures and perpetration in the feminist-informed model. In both models, predictors of stalking were different than those for other types of perpetration. Future studies should replicate this research and determine the utility of combining models.

Parents' physical victimization in childhood and current risk of child maltreatment: the mediator role of psychosomatic symptoms

OBJECTIVE

To test the potential mediation effect of psychosomatic symptoms on the relationship between parents' history of childhood physical victimization and current risk for child physical maltreatment.

METHODS

Data from the Portuguese National Representative Study of Psychosocial Context of Child Abuse and Neglect were used. Nine-hundred and twenty-four parents completed the Childhood History Questionnaire, the Psychosomatic Scale of the Brief Symptom Inventory, and the Child Abuse Potential Inventory.

RESULTS

Mediation analysis revealed that the total effect of the childhood physical victimization on child maltreatment risk was significant. The results showed that the direct effect from the parents' history of childhood physical victimization to their current maltreatment risk was still significant once parents' psychosomatic symptoms were added to the model, indicating that the increase in psychosomatic symptomatology mediated in part the increase of parents' current child maltreatment risk.

DISCUSSION

The mediation analysis showed parents' psychosomatic symptomatology as a causal pathway through which parents' childhood history of physical victimization exerts its effect on increased of child maltreatment risk. Somatization-related alterations in stress and emotional regulation are discussed as potential theoretical explanation of our findings. A cumulative risk perspective is also discussed in order to elucidate about the mechanisms that contribute for the intergenerational continuity of child physical maltreatment.

Breaking the links in intergenerational violence: an emotional regulation perspective

The saying "violence begets violence" is an apt descriptor of the cycle of family violence, as children who witness parental violence are at high risk for repeating family violence in their own adult intimate relationships. Neuroscience research suggests that emotional regulation may be an important link in the heritability of family violence, and promotes awareness of the importance of internalizing as well as externalizing responses to stress, neglect, and abuse. This study argues for a trauma-informed approach to identifying children and parents whose symptoms of emotional dysregulation may be otherwise overlooked, and for an expanded approach to treatment that incorporates family systems and emotional regulation strategies.

Predictors of physical intimate partner violence in the lives of young women: victimization, perpetration, and bidirectional violence

BACKGROUND

Dating violence in young people is highly prevalent, and bidirectional violence characterizes most violent relationships. However, there is limited data on predictors of bidirectional violence in young relationships.

PURPOSE

To examine the frequency of victimization, perpetration, and bidirectional physical violence in young women's relationships and compare individual and relationship characteristics across violence profiles.

METHODS

Six hundred eighteen young women visiting an urban reproductive health care clinic completed an anonymous survey using the Conflict in Adolescent Dating Relationships Inventory to measure their experience of violence with a partner in the last year.

RESULTS

Thirty-four percent of women reported at least one instance of physical violence (3% "victim only" 12% "perpetrator only," 19% "bidirectional"). The frequency of violence in the previous year within the bidirectional profile was significantly higher than both the victim-only and perpetrator-only profiles. In all adjusted models, younger age, childhood sexual abuse, witnessing parental intimate partner violence (IPV), and relationship length remained significant. Black race was predictive of both perpetration and bidirectional violence, but not victimization. Compared to nulliparous women or those with one previous pregnancy, those who had had two or more had twice the odds of both victimization and bidirectional, but no increase in odds of perpetration.

CONCLUSIONS

Bidirectional violence was the most common profile and was associated with the highest frequency of violent behaviors. Contrary to expectation, only two variables differed significantly across the three violence profiles. However, as hypothesized, bidirectional relationships were characterized by longer length, lending moderate support for social learning theory as one explanation underlying the occurrence of bidirectional violence.

Intimate Partner Violence among California Couples: Multilevel Analysis of Environmental and Partner Risk Factors

This study assessed the extent to which environmental (Census block-group alcohol outlet density, neighborhood demographic characteristics) and partner risk factors (e.g., hazardous drinking, psychosocial characteristics) contribute to the likelihood of intimate partner violence among 1,753 couples residing in 50 medium-to-large California cities. Multilevel logistic regression models were used to analyze the role of alcohol outlets (off-premise outlets, bars/pubs and restaurants), neighborhood demographic characteristics, and partner risk factors in relation to male-to-female partner violence (MFPV) and female-to-male partner violence (FMPV) risk. Approximately 12% of couples reported past-year partner violence. Results showed that none of the environmental measures were related to MFPV or FMPV. Male partner's impulsivity and each partner's adverse childhood experiences were associated with MFPV risk. Risk factors for FMPV were male partner's impulsivity and frequency of intoxication and female partner's adverse childhood experiences. Individual/couple characteristics appear to be the most salient IPV risk factors. The male partner's heavy drinking may lead to negative partner/spousal interactions that result in FMPV. The male partner's impulsivity, and each partner's adverse childhood experiences, may potentiate couple conflict and result in aggression. Interventions that target prevention of family dysfunction during childhood may help reduce interpersonal violence in adulthood.

Adverse childhood experiences, posttraumatic stress disorder symptoms, and emotional intelligence in partner aggression

Intimate partner violence (IPV) has been linked to childhood abuse, posttraumatic stress disorder (PTSD), and low emotional intelligence (EI). Relationships among adverse childhood experiences (ACE), PTSD symptoms, and partner aggression (i.e., generalized tendency to aggress toward one's partner) were assessed in 108 male IPV offenders. It was hypothesized that ACE is positively correlated with partner aggression, PTSD mediates the ACE-aggression relationship, and the ACE-PTSD-aggression mediation varies by selected EI facets. Results indicate that ACE has an indirect effect on partner aggression via PTSD and PTSD mediates the ACE-aggression link when emotional self-regulation is low and when intuition (vs. reason) is high. Trauma-exposed IPV offenders may benefit from comprehensive treatments focusing on PTSD symptoms, emotional control, and reasoning skills to reduce aggression.

The impact of childhood maltreatment on PTSD symptoms among female survivors of intimate partner violence

OBJECTIVE

Intimate partner violence (IPV) survivors often report histories of childhood maltreatment, yet the unique contributions of childhood maltreatment on IPV survivors' distinct posttraumatic stress disorder (PTSD) symptoms remain inadequately understood.

METHOD

Using interview and self-report measures, we examined IPV as a potential mediator of the association between childhood maltreatment and severity of PTSD symptom clusters (reexperiencing, avoidance, numbing, and hyperarousal) among a sample of 425 women seeking help for recent IPV.

RESULTS

Structural equation modeling demonstrated that while both childhood maltreatment and IPV were both positively associated with PTSD symptom clusters, IPV did not mediate the association between childhood maltreatment and severity of PTSD symptom clusters among acute IPV survivors.

CONCLUSIONS

Childhood maltreatment has persistent effects on the PTSD symptoms of IPV survivors, suggesting that child maltreatment may need to be addressed in addition to IPV during PTSD treatment.
