DIFFERENTIATION AMONG TYPES OF INTIMATE PARTNER VIOLENCE: RESEARCH UPDATE AND IMPLICATIONS FOR INTERVENTIONS

A growing body of empirical research has demonstrated that intimate partner violence is not a unitary phenomenon and that types of domestic violence can be differentiated with respect to partner dynamics, context, and consequences. Four patterns of violence are described: Coercive Controlling Violence, Violent Resistance, Situational Couple Violence, and Separation‐Instigated Violence. The controversial matter of gender symmetry and asymmetry in intimate partner violence is discussed in terms of sampling differences and methodological limitations. Implications of differentiation among types of domestic violence include the need for improved screening measures and procedures in civil, family, and criminal court and the possibility of better decision making, appropriate sanctions, and more effective treatment programs tailored to the characteristics of different types of partner violence. In family court, reliable differentiation should provide the basis for determining what safeguards are necessary and what types of parenting plans are appropriate to ensure healthy outcomes for children and parent–child relationships.     

Perpetrator programmes for partner violence: Are they based on ideology or evidence?

Purpose. The ideologically based view of intimate partner violence has traditionally influenced policy and practice in modern western nations and dominated cross‐national research and practice. This review considers the validity of the position statement of a British organization responsible for accrediting many male perpetrator programmes in the statutory, voluntary, and private sector as an example of this ideological influence. Method. The position statement, informed by the patriarchal view of partner violence, is evaluated using empirical evidence from various branches of the social sciences, including psychology, that have not been guided by the patriarchal view. Results. Overwhelming empirical evidence is presented, which refutes ideologically driven assumptions that have been put forward to guide current practice and evaluation of it. Conclusions. This review highlights the need to investigate intimate partner violence from a scientific and gender‐inclusive perspective. The implications for psychological practice are discussed.     

Reconceptualizing and operationalizing context in survey research on intimate partner violence

Survey research in the field of intimate partner violence is notably lacking in its attention to contextual factors. Early measures of intimate partner violence focused on simple counts of behaviors, yet attention to broader contextual factors remains limited. Contextual factors not only shape what behaviors are defined as intimate partner violence but also influence the ways women respond to victimization, the resources available to them, and the environments in which they cope with abuse. This article advances methods for reconceptualizing and operationalizing contextual factors salient to the measurement of intimate partner violence. The analytic focus of the discussion is on five dimensions of the social context: the situational context, the social construction of meaning by the survivor, cultural and historical contexts, and the context of systemic oppression. The authors consider how each dimension matters in the measurement of intimate partner violence and offer recommendations for systematically assessing these contextual factors in future research.     

Trends in intimate partner violence: 1980-2008

Research on trends in partner violence has primarily relied on official measures of victimization focusing primarily on women's risk for intimate partner homicide. The current study uses 28 years of data from the National Crime Victimization Survey (NCVS) to examine the trends of intimate partner violence against female victims and identify variation in women's risk as a function of race and employment. Although it has been theorized that employment is correlated with the risk of intimate partner victimization for women, research has not thoroughly addressed this in a longitudinal context. In addition, research has not explored the extent to which intimate partner violence is correlated with the combined variables of race and employment. The authors find that between 1980 and the mid-2000s employment is associated with an increase in women's risk for intimate partner violence. However, the conclusion that the rate of victimization is higher for employed women appears to be partly contingent on the victims' race. The trend for non-White unemployed women appears to be relatively comparable to both White and non-White employed women, at least for the first 15 years of the series.     

Trajectories of non-intimate partner and intimate partner homicides, 1980-1999: The importance of rurality

Research had consistently shown that intimate partner homicide rates had been on a steady downward decline over the past two decades; however, a relatively recent movement in intimate partner homicide research had emphasized the need for further dissecting the aggregate trends by factors such as gender, race, victim-offender relationship, and same-sex partners. Taking this a step forward, this study utilized trajectory analysis for comparing and contrasting non-intimate partner homicide and intimate partner homicide rates over time in order to explore the importance of rurality when investigating intimate partner violence. Results of the analysis indicated that although intimate partner homicide rates had been declining over the 1980-1999 period for the majority of the 1,341 U.S. counties examined, there was evidence that rurality was significantly associated with an increased likelihood of assignment to a non-declining intimate partner homicide trajectory. In light of the findings, the authors also consider how these results can direct future research on intimate partner violence in rural areas.     

Reflections on partner violence: 20 years of research and beyond

The authors reflect on past research and technology as well as their hopes for future innovations within the field of intimate partner violence. They review work that has contributed to current conceptual definitions of partner violence, particularly those that have shaped the field's broadened perspective. They discuss technological and measurement innovations that have contributed to more accurate assessments of violence prevalence. The authors believe that via these technologies, the true extent of violence within the home has been made known. In conclusion, the authors argue that to reduce violence between partners, there is an overwhelming need for future researchers to build on past data, develop improved theories, and apply those ideas to prevention and intervention techniques and programs. Furthermore, they believe that it is imperative for current and future programs to be extensively evaluated and tested for their effectiveness.     

Understanding gender-specific intimate partner homicide: A theoretical and domestic service-oriented approach

Research on intimate partner homicide has increased in recent years, partially due to growing efforts to disaggregate homicides into meaningful categories but also because of a growing interest in policy responses toward domestic violence. Much of this research tends to focus on two perspectives—exposure reduction and the backlash/retaliation hypotheses—when explaining the link between intimate partner homicide and domestic violence resources. Support has been found for both approaches even though they offer contradictory predictions. This frustrating finding is further complicated by methodological issues, such as the inability to address the rare nature of these events, offer a wide range of domestic violence services and resources and control for structural characteristics of urban areas where violence is found. This issue is addressed by offering a systematic examination of male- and female-victim intimate partner homicide in 2000. The current study investigates both exposure reduction and backlash arguments, in addition to economic deprivation and a number of structural factors relevant to homicide rates. Results suggest that while these perspectives are relevant to intimate partner homicides, there are statistically significant differences across the gender-specific models once the corrected statistical test for coefficient equality is estimated.     

Intimate Partner Violence Among Hispanics: A Review of the Literature

This paper analyzed the existing literature on risk and protective factors for intimate partner violence among Hispanics using the four-level social-ecological model of prevention. Three popular search engines, PsycINFO, PubMed, and Google Scholar, were reviewed for original research articles published since the year 2000 that specifically examined factors associated with intimate partner violence (IPV) among Hispanics. Factors related to perpetration and victimization for both males and females were reviewed. Conflicting findings related to IPV risk and protective factors were noted; however, there were some key factors consistently shown to be related to violence in intimate relationships that can be targeted through prevention efforts. Future implications for ecologically-informed research, practice, and policy are discussed.     

Implementing a Strengths-Based Approach to Intimate Partner Violence Worldwide

Family violence is a core social issue in every country around the world. The extent and consequence of family violence as a major problem has received increased attention around the world. The focus of the present study is not only to inform about intimate partner violence (IPV) that occurs in individual countries, but to illustrate how individuals, families, communities, and cultures use their strengths to overcome the challenges that violence presents. An analysis of 16 countries, including 17 cultures is represented and includes all seven of the world’s major geocultural areas. Qualitative methodology was used to examine the stories of intimate partner violence in which similarities and differences across cultures were discovered resulting in a theoretical discussion of findings. The International Family Strengths Model was applied to examine the family strengths, community strengths, and cultural strengths used to mitigate family violence worldwide. Individual strengths emerged as a new and important component of the model. Suggestions for change include recognition of differing solutions across cultures, the need for mediation and policy changes, and the importance of empowerment.     

Exposure Reduction or Retaliation? The Effects of Domestic Violence Resources on Intimate‐Partner Homicide

Rates of homicide involving intimate partners have declined substantially over the past 25 years in the United States, while public awareness of and policy responses to domestic violence have grown. To what extent has the social response to domestic violence contributed to the decline in intimate‐partner homicide? We evaluate the relationship between intimate‐partner homicide and domestic violence prevention resources in 48 large cities between 1976 and 1996. Controlling for other influences, several types of prevention resources are linked to lower levels of intimate‐partner homicide, which we interpret in terms of their capacity to effectively reduce victims' exposure to abusive or violent partners. Other resources, however, are related to higher levels of homicide, suggesting a retaliation effect when interventions stimulate increased aggression without adequately reducing exposure. In light of other research on deficiencies in accessing and implementing prevention resources, our results suggest that too little exposure reduction in severely violent relationships may be worse than none at all.     

Responding to violence against women: social science contributions to legal solutions

Violence against women represents a serious problem in America. Not only does intimate partner violence represent a significant threat to women, but it also counts among its victims, children living in the violent household. By its very nature, intimate partner or domestic violence may be approached as either a legal or a social problem. However, there is a shortage of legal approaches that have been informed by sound social science research. One promising framework for developing such integrated responses to intimate partner violence is therapeutic jurisprudence, which encourages legal professionals to work closely with social scientists to develop system responses based on empirical data. Such an approach contrasts sharply with the current practice of developing law based on assumptions, which frequently reflect traditional paternalistic and sexist attitudes toward women. This paper begins by examining the current theories and scientific knowledge on domestic violence with particular emphasis on the supporting data. A theoretical framework for conceptualizing domestic violence characterized as patriarchal terrorism as distinct from common couple violence is examined and offered as a means of explaining inconsistencies in research findings. Following a review of current legal responses to domestic violence, the paper concludes by outlining alternative strategies and recommendations for future efforts that are supported by current theory and research.     

Intimate partner violence, PTSD, and adverse health outcomes

The high prevalence of adverse health outcomes related to intimate partner violence (IPV) is well documented. Yet we know little about the pathways that lead to adverse health outcomes. Research concerning the psychological, biological, neurological, behavioral, and physiological alterations following exposure to IPV--many of which are associated with posttraumatic stress disorder (PTSD)--represents a promising area of empirical discovery. New technologies and interdisciplinary collaborative efforts are required to integrate diverse methodologies and to apply new findings to improving the health and well being of those affected by IPV. This article focuses on victimization by IPV and addresses the most important research findings in the last 20 years (health and mental health burden of IPV), the most important research issue for the next decade (pathways between IPV and adverse health outcomes), and the most promising methodological innovation for the study of IPV (integrated, interdisciplinary, biobehavioral methodology).     

Examining an Extension of Johnson’s Hypothesis: Is Male Perpetrated Intimate Partner Violence More Underreported than Female Violence?

This paper examines two hypotheses about under-reporting in intimate partner violence data. The first hypothesis holds that significant amounts of under-reporting of intimate partner violence occur due to stigma. The second examines the empirical evidence behind Johnson’s (Journal of Marriage and the Family 57:238–294, 1995) contention that controversial findings of equal rates of intimate partner violence perpetration among men and women occur through a combination of heterogeneity in type of intimate partner violence and missing data. E.M. and Data Augmentation are used to correct for item non-response in the Project on Human Development in Chicago Neighborhoods. Strong support is found for general under-reporting; weak support is found for greater under-reporting of male violence.     

Improving violence intervention outcomes by integrating alcohol treatment

There is extensive empirical and theoretical support for a link between alcohol use and intimate partner violence. Recent innovations in the assessment of these constructs have shown a strong temporal link between alcohol use and intimate partner violence. The majority of men participating in batterer intervention programs have alcohol problems, and these men are at very high risk for violence recidivism. Research has shown substantial decreases in partner violence among alcoholics subsequent to obtaining alcohol treatment. It is likely that violence outcomes could be significantly improved by incorporating alcohol treatment as a standard component of batterer intervention programs.     

Of mice and men: will the intersection of social science and genetics create new approaches for intimate partner violence?

The past two decades have yielded a recognition that intimate partner violence is ubiquitous. Although violence within relationships is bidirectional, there is acknowledgment that violence directed against women is more persistent and dangerous. Strategies for treatment of men have been largely unsuccessful, and studies of women centered approaches to prevention are in their infancy. An emerging concept in the brain-behavior field is the recognition of genetics as a powerful influence on aggressive and violent behaviors. Mouse models of human health and disease have facilitated our understanding of the role of genetics in the manifestation of these traits. There is a need to push the boundaries of research on intimate partner violence by adopting biosocial approaches to understand its causes.     

Gender Differences in Specialization in Intimate Partner Violence: Comparing the Gender Symmetry and Violent Resistance Perspectives

Research on male domestic violence offenders has typically considered them to be highly specialized offenders, and specialized theories and policies have been developed to address this type of offending. Some scholars have suggested that intimate partner violence is not as specialized as has been previously assumed. Especially in terms of gender differences, intimate partner violence research and theory suggest some variability in the level of specialization apparent for offenders. The current study uses the gender symmetry and violent resistance perspectives of women’s use of intimate partner violence to examine gender differences in specialization among a sample of intimate partner violence arrestees. Analyses employed multivariate models estimating the diversity index as a measure of specialization in general and multilevel item response theory to assess specialization in intimate partner violence specifically. Results indicate that female arrestees demonstrate significantly greater levels specialization as compared to male arrestees, providing support for the violent resistance perspective. Implications of these results and directions for future research are discussed.     

The relationship between marijuana use and intimate partner violence in a nationally representative, longitudinal sample

Intimate partner violence is a significant public health problem, as these behaviors have been associated with a number of negative health outcomes including illicit drug use, physical injury, chronic pain, sexually transmitted diseases, depression, and posttraumatic stress disorder. The current study examined the association between marijuana use and intimate partner violence using a longitudinal survey of adolescents and young adults ages 15 to 26 years. Data were obtained from 9,421 adolescents in the National Longitudinal Study of Adolescent Health (Add Health) Waves 1 through 4 (1995-2008). Marijuana use was measured in the past year at each wave and participants were categorized as "users" or "nonusers." Partner violence was constructed using six items (three pertaining to victimization and three concerning perpetration) from Wave 4 (2007-2008). Using these six items, participants were categorized as "victims only," "perpetrators only," or "victims and perpetrators." Survey multinomial regression was used to examine the relationship between marijuana use and intimate partner violence. Consistent use of marijuana during adolescence was most predictive of intimate partner violence (OR = 2.08, p < .001). Consistent marijuana use (OR = 1.85, p < .05) was related to an increased risk of intimate partner violence perpetration. Adolescent marijuana use, particularly consistent use throughout adolescence, is associated with perpetration or both perpetration of and victimization by intimate partner violence in early adulthood. These findings have implications for intimate partner violence prevention efforts, as marijuana use should be considered as a target of early intimate partner violence intervention and treatment programming.     

A test of social learning and intergenerational transmission among batterers

This research examined the direct and indirect transmission of family-of-origin violence among a sample of male domestic violence offenders. Intergenerational transmission of violence was tested by examining the effects of childhood corporal punishment experiences and witnessing inter-parental physical violence on the odds of reporting minor and severe intimate partner violence perpetration in adulthood. Social learning mechanisms were applied to examine the relationship between abuse experiences and the incidence of minor and severe forms of intimate partner violence. Use of a sample of 204 male domestic batterers attending court-mandated family violence intervention programs in an urban setting revealed considerable variation in minor and severe intimate partner violence. Results from logistic regression models suggested intergenerational transmission and social learning provided distinct mechanisms for both minor and severe forms of intimate partner violence.     

THE POLITICS OF RESEARCH: THE USE,ABUSE, AND MISUSE OF SOCIAL SCIENCE DATA—THE CASES OF INTIMATE PARTNER VIOLENCE

This article examines the issue of how research is utilized, abused, and misused in policy and practice in the area of intimate partner violence (IPV). The article reviews and critically analyzes facts set forth for the purpose of claiming that IPV is a significant social problem and finds that many of these facts lack empirical support. The lack of evidence that supports theoretical explanations for IPV and recommended interventions hinders the ability to adequately respond to the problem of IPV.     

An exploratory study of women arrested for intimate partner violence: violent women or violent resistance?

With the advent of mandatory and pro-arrest laws for incidents of intimate partner violence, there has been an increase in the number of women arrested for domestic violence. Several explanations are posed in the literature that attempt to explain such a rise, including the hypothesis that women are being arrested not for offensive violence but rather for defensive violence. Few studies, however, have used empirical data to support such arguments. This exploratory study examines the characteristics of women arrested for intimate personal violence. Particular attention is paid to women arrested with their partner (i.e., dual arrestees) and the contextual characteristics of dual arrestee incidents. Important differences are uncovered in the context and consequences of arrest for dual arrestees (n = 21) compared to women arrested alone as the offender (n = 49). Implications of these findings and further research directions are discussed.
