Methods for estimating medical expenditures attributable to intimate partner violence

Health-Related Costs of Intimate Partner Violence: Using Linked Police and Health Registers

This study aims to estimate direct health-related costs for victims of intimate partner violence (IPV) using nationwide linked data based on police reports and two healthcare registers in Finland from 2015 to 2020 (N = 21,073). We used a unique register dataset to identify IPV victims from the data based on police reports and estimated the attributable costs by applying econometric models to individual-level data. We used exact matching to create a reference group who had not been exposed to IPV. The mean, unadjusted, attributable healthcare cost for victims of IPV was €6,910 per individual over the 5-year period after being first identified as a victim. When adjusting for gender, age, education, occupation, and mental-health- and pregnancy-related diagnoses, the mean attributable health-related cost for the 5 years was €3,280. The annual attributable costs of the victims were consistently higher than those for nonvictims during the entire study period. Thus, our results suggest that the adverse health consequences of IPV persist and are associated with excess health service use for 5 years after exposure to IPV. Most victims of IPV were women, but men were also exposed to IPV, although the estimates were statistically significant only for female victims. Victims of IPV were over-represented among individuals outside the labor force and lower among those who were educated. The total healthcare costs of victims of IPV varied according to the socioeconomic factors. This study highlights the need for using linked register data to understand the characteristics of IPV and to assess its healthcare costs. The study results suggest that there is a significant socioeconomic gradient in victimization, which could also be useful to address future IPV prevention and resource allocation.

Intimate partner violence during pregnancy in COVID-19 pandemic: a cross-sectional study from South-west of Iran

BACKGROUND

Intimate partner violence (IPV) against pregnant women can cause several complications for the mother and her baby, which are life-threatening. Thus, we aimed to find the prevalence of IPV and its associated factors in pregnant women in Shiraz, Iran.

METHODS

This cross-sectional study was conducted among pregnant mothers in Shiraz between July 2020 and January 2021. The questionnaire consisted of four parts: demographic data, socio-economic status (SES), obstetric and medical history, and questions about IPV. Univariate analysis was performed using Chi-square, McNemar, or Fisher's exact test, and variables with p-value < 0.20 were included in Logistic regression. The odds ratio and CI 95% for variables with p-value < 0.05 were considered statistically significant.

RESULTS

The overall prevalence of IPV was 93.1% among 830 pregnant women in Shiraz. Psychological violence was the most prevalent type (92.9%), followed by sexual (11%) and physical (7.7%) violence. High SES (OR = 3.21, (CI:1.61-6.41)) was the only risk factor for overall violence, and the age group, 30-34, was a risk factor for physical violence. Mother-desired pregnancy (OR = 26 (Cl:0.09-0.79)) and father-desired pregnancy (OR = 0.91, (CI:0.22-3.80)) were protective factors against physical and sexual violence, respectively. Furthermore, Psychological violence and sexual violence increased during COVID-19 Pandemic (P.value < 0.05).

CONCLUSION

According to the obtained results, the prevalence of IPV during pregnancy in Shiraz was very concerning, especially psychological violence. Improving conflict-solving skills among family members and addressing economic problems could be considered by health policymakers when designing interventional programs and policies to reduce IPV during pregnancy.

The Economic Burden of Intimate Partner Violence in Colombia: Estimated Health Costs Among Females Aged 13-24

BACKGROUND

Intimate partner violence (IPV) is the most pervasive form of gender-based violence, often first experienced in adolescence. While the prevalence of IPV is known to be exacerbated in humanitarian settings, little is known in regard to the economic burden of IPV between conflict-affected and non-conflicted-affected groups of women and girls. This top-down costing study examines the total health burden of physical IPV in Colombia, and whether these costs differ by conflict exposure.

METHODS

We utilized a nationally representative sample of 13-24-year-old females from the Violence Against Children Surveys (VACS) in Colombia conducted in 2018. Using physical IPV prevalence, the analysis was conducted in four steps: 1) estimate the relative risk of seven IPV-associated health outcomes among the sample and subgroups, 2) estimate the population attributable fraction of IPV for each health outcome, 3) quantify the burden of IPV in disability-adjusted life years (DALYs), and 4) assign health costs in US dollars to the estimated DALYs.

RESULTS

We found that the single year health burden associated with physical IPV was $90.6 million USD. Moreover, nearly 40% of the economic burden of physical IPV among females aged 13-24 in Colombia was from those who were conflict-affected (24%).

CONCLUSION

Our findings demonstrate that at least 16% of the overall health costs among females 13-24 in Colombia is from the preventable epidemic of physical IPV. In order to prevent and mitigate the costs of gender-based violence, multi-lateral and government investment is critically needed to prevent IPV and support women and girls.

Advancing our understanding of the intersection between emotion regulation and alcohol and drug use problems: Dyadic analysis in couples with intimate partner violence and alcohol use disorder

BACKGROUND

An extensive body of literature has linked emotion regulation to alcohol and drug use problems, including among populations characterized by intimate partner violence (IPV). Advancing this research, the goal of the current study was to examine cognitive emotion regulation strategies and alcohol and drug use problems within a dyadic framework. Specifically, we examined actor and partner effects of maladaptive and adaptive cognitive emotion regulation strategies on alcohol and drug use problems.

METHODS

Eighty-four romantic couples (N = 168 total participants) participating in a randomized controlled trial who reported physical IPV and an alcohol use disorder completed self-reported measures of cognitive emotion regulation as well as alcohol and drug use problems.

RESULTS

Regarding actor effects, men's greater use of maladaptive cognitive emotion regulation strategies was positively related to their alcohol use problems (p < .001), whereas both women's (p = .02) and men's (p = .047) greater use of adaptive cognitive emotion regulation strategies was negatively related to their own alcohol use problems. In terms of partner effects, men's greater use of maladaptive cognitive emotion regulation strategies (p = .001) and less use of adaptive cognitive emotion regulation strategies (p = .017) was related to their partners' greater drug use problems.

CONCLUSIONS

Findings replicate and extend existing work in this area, showing that men's and women's emotion regulation strategies are related to their own alcohol and drug use problems and that men's cognitive emotion regulation strategies are also related to their partners' drug use problems.

Acceptance of Intimate Partner Violence in Rural Malawi: An Empirical Analysis on the Impacts of Lineage and AIDS Conversation Networks

Acceptance of intimate partner violence (IPV) is both a barrier to its reduction and a strong predictor of prevalence. This study examines whether lineage and AIDS conversation networks impact acceptance of IPV among men and women in rural Malawi. The sample consists of 4,422 male and female respondents from the 2001, 2004, and 2006 waves of the Malawi Longitudinal Study of Families and Health (MLSFH). The longitudinal nature of the data enables us to use not only random effects models in the empirical analysis, but also fixed effects models, which help alleviate omitted variable bias. Our findings suggest that in the patrilineal Northern Region of Malawi, AIDS conversation networks may be conducive toward reducing acceptance of IPV. However, AIDS conversation networks may reinforce violent norms in the Central Region of Malawi as men with larger AIDS conversation networks are more accepting of IPV. These findings imply there may be an opportunity to incorporate network-based policies to reduce IPV, and lineage may be an important consideration in forming policies to alleviate IPV. In addition, we find a relatively strong age-acceptance gradient, with younger, never-married individuals being less accepting of IPV than older, married individuals. This finding may help inform intervention targeting as older, married women in Malawi may be at a higher risk of IPV.

Association of behavioral health factors and social determinants of health with high and persistently high healthcare costs

A high proportion of U.S. health care costs are attributable to a relatively small proportion of patients. Understanding behavioral and social factors that predict initial and persistent high costs for these "high utilizers" is critical for health policy-makers. This prospective observational study was conducted at Kaiser Permanente Northern California (KPNC), an integrated healthcare delivery system with 4.1 million members. A stratified random sample of high-cost vs. non-high-cost adult KPNC members matched by age, gender, race/ethnicity, type of health insurance, and medical severity (N = 378) was interviewed between 3/14/2013 and 3/20/2014. Data on health care costs and clinical diagnoses between 1/1/2008 and 12/31/2012 were derived from the electronic health record (EHR). Social-economic status, depression symptoms, adverse childhood experiences (ACEs), interpersonal violence, financial stressors, neighborhood environment, transportation access, and patient activation and engagement were obtained through telephone interviews. Initial and subsequent high-cost status were defined as being classified in top 20% cost levels over 1/1/2009-12/31/2011 and 1/1/2012-12/31/2012, respectively. Psychiatric diagnosis (OR 2.55, 95% CI 1.52-4.29, p < 0.001), financial stressors (OR 1.97, 95% CI 1.19-3.26, p = 0.009), and ACEs (OR 1.10, 95% CI 1.00-1.20, p = 0.051) predicted initial high-cost status. ACEs alone predicted persistent high-cost status in the subsequent year (OR 1.12, 95% CI 1.00-1.25, p = 0.050). Non-medical factors such as psychiatric problems, financial stressors and adverse childhood experiences contribute significantly to the likelihood of high medical utilization and cost. Efforts to predict and reduce high utilization must include measuring and potentially addressing these factors.

Psychological and relational correlates of intimate partner violence profiles among pregnant adolescent couples

We sought to identify relationship and individual psychological factors that related to four profiles of intimate partner violence (IPV) among pregnant adolescent couples: no IPV, male IPV victim only, female IPV victim only, mutual IPV, and how associations differ by sex. Using data from a longitudinal study of pregnant adolescents and partners (n = 291 couples), we used a multivariate profile analysis using multivariate analysis of covariance with between and within-subjects effects to compare IPV groups and sex on relationship and psychological factors. Analyses were conducted at the couple level, with IPV groups as a between-subjects couple level variable and sex as a within-subjects variable that allowed us to model and compare the outcomes of both partners while controlling for the correlated nature of the data. Analyses controlled for age, race, income, relationship duration, and gestational age. Among couples, 64% had no IPV; 23% male IPV victim only; 7% mutual IPV; 5% female IPV victim only. Relationship (F = 3.61, P < .001) and psychological (F = 3.17, P < .001) factors differed by IPV group, overall. Attachment anxiety, attachment avoidance, relationship equity, perceived partner infidelity, depression, stress, and hostility each differed by IPV profile (all P < .01). Attachment anxiety, equity, depression and stress had a significant IPV profile by sex interaction (all P < .05). Couples with mutual IPV had the least healthy relationship and psychological characteristics; couples with no IPV had the healthiest characteristics. Females in mutually violent relationships were at particularly high risk. Couple-level interventions focused on relational issues might protect young families from developing IPV behaviors. Aggr.

Intimate partner aggression-related shame and posttraumatic stress disorder symptoms: The moderating role of substance use problems

A dearth of literature has examined the consequences of women's use of aggression in intimate relationships. Women's use of aggression against their intimate partners, regardless of their motivation (e.g., self-defense, retaliation), may elicit shame. Shame, in turn, may contribute to the maintenance and/or exacerbation of posttraumatic stress disorder (PTSD) symptoms, which are commonly experienced in this population. Further, emerging research suggests that emotionally avoidant coping strategies, such as substance use, may strengthen the relation between shame and PTSD symptoms. The goal of the present study was to examine whether women's shame concerning their use of intimate partner aggression is associated with their PTSD symptoms, and whether drug and alcohol use problems moderate this association. Participants were 369 community women who had used and been victimized by physical aggression in an intimate relationship with a male partner in the past six months. The intimate partner aggression-related shame × drug (but not alcohol) use problems interaction on PTSD symptom severity was significant. Analysis of simple slopes revealed that women's intimate partner aggression-related shame was positively associated with their PTSD symptoms when drug use problems were high, but not when drug use problems were low. Findings have implications for the potential utility of PTSD treatments targeting a reduction in shame and maladaptive shame regulation strategies (i.e., drug use) in this population. Aggr.

Physical violence against pregnant women by an intimate partner, and adverse pregnancy outcomes in Mazandaran Province, Iran

Background and Aim:

Violence against women during pregnancy is linked to poor outcome of pregnancy, which is reported to have widespread in Iran. The aim of this study was to determine the prevalence of physical violence against women by an intimate partner during pregnancy, and to assess the impact of this physical violence on pregnancy outcomes.

Materials and Methods:

A prospective cohort study was conducted on the characteristics of pregnant women in urban areas and related violence. The modified standard World Health Organization Domestic Violence Questionnaire was used to classify pregnant women and domestic violence. A total of 1461 pregnant women were selected using cluster sampling. The association between sociodemographic with intimate partner violence (IPV) and IPV with pregnancy outcomes was determined using logistic regression.

Results:

Of these, 206 (14.1%) (confidence interval = 12.3-15.9) reported physical IPV during pregnancy. The adjusted odds ratio for IPV in illiterate women or those with primary level of education (0.001), secondary level education (0.003), and in low income households (0.0001) were significantly higher than in those women with university level education and in higher income households. After adjusting for suspected confounding factors, the women with a history of violence by partners had 1.9 fold risk of premature rupture of membranes, and a 2.9 fold risk of low birth weight compared to women who did not experience any violence from their partners.

Conclusion:

The results of this research indicated that the prevalence of IPV was high among pregnant women. Therefore, it is necessary to emphasize the screening of pregnant women at Primary Health Centers to prevent physical abuse.

Genetic associations with intimate partner violence in a sample of hazardous drinking men in batterer intervention programs

The etiology of intimate partner violence (IPV) is multifactorial. However, etiological theories of IPV have rarely included potential genetic factors. The purpose of the present study was to examine whether a cumulative genetic score (CGS) containing the monoamine oxidase A (MAOA) and the human serotonin transporter gene linked polymorphism (5-HTTLPR) was associated with IPV perpetration after accounting for the effects of alcohol problems, drug problems, age, and length of relationship. We obtained DNA from 97 men in batterer intervention programs in the state of Rhode Island. In the full sample, the CGS was significantly associated with physical and psychological aggression and injuries caused to one's partner, even after controlling for the effects of alcohol problems, drug problems, age, and length of relationship. Two of the men in the sample likely had Klinefelter's syndrome, and analyses were repeated excluding these two individuals, leading to similar results. The implications of the genetic findings for the etiology and treatment of IPV among men in batterer intervention programs are briefly discussed.

Evidence for a curvilinear dose-response relationship between avoidance coping and drug use problems among women who experience intimate partner violence

Women who experience intimate partner violence (IPV) are at heightened risk for drug use problems. While prevailing models of drug use suggest that IPV-exposed women use drugs in an effort to escape or avoid negative affect, a dearth of literature has examined the role of avoidance coping in drug use problems within this population. Given recent suggestions that flexible, situationally appropriate use of avoidance coping may be adaptive, particularly when confronted with highly stressful situations, we hypothesized that avoidance coping and drug use problems would demonstrate a curvilinear, U-shaped dose-response relationship. Participants were 147 community-recruited women experiencing IPV. Consistent with our hypotheses, moderate levels of avoidance coping were associated with lower levels of drug use problems, whereas high and low levels of avoidance coping were associated with higher levels of drug use problems. Findings highlight the complex relationship between avoidance coping and drug use problems and suggest that avoidance coping, when used in moderation, may be an adaptive strategy for coping with relational conflict among women who experience IPV.

Bridging intimate partner violence and the human brain: a literature review

Past studies mainly focused on the physical and structural brain injuries in women survivors with a history of intimate partner violence (IPV), but little attention has been given to the biological impact and cognitive dysfunction resulting from such psychological stress. In this article, we aim to establish the connection between IPV and the brain by reviewing current literature examining (1) the biological mechanisms linking IPV, stress, and the brain; (2) the functional and anatomical considerations of the brain in abused women; and (3) the abused women's behavioral responses to IPV, including fear, pain, and emotion regulation, by utilizing functional neuroimaging. The major significance of this study is in highlighting the need to advance beyond self-reports and to obtain scientific evidence of the neurological impact and cognitive dysfunction in abused women with a history of IPV, an area in which current literature remains at a descriptive level.

The economic burden of intimate partner violence in ecuador: setting the agenda for future research and violence prevention policies

Introduction: Intimate partner violence (IPV) is a widespread social structural problem that affects a great proportion of Ecuadorian women. IPV is a sexually, psychologically, or physically coercive act against an adult or adolescent woman by a current or former intimate partner. Not-for-profit groups in Ecuador report that 70% of women experience 1 of the forms of IPV sometime during their lifetime, but population-based surveys suggest that 41% of Ecuadorian women are exposed to emotional violence, 31% physical violence, and 12% sexual violence by their spouse or partner over their lifetime. Despite the high prevalence, the response of the Ecuadorian government has been insufficient to reduce the number of victims and to provide adequate legal and health services for the prevention and treatment of IPV. Given the power of economic data to influence policy making, the goal of this study is to produce the first estimate of the economic impact of IPV in Ecuador and to identify the policy paths in which these estimates would have the greatest impact for Ecuador.

Methods: Using a bottom-up method for estimating the economic burden of IPV and a national prevalence of IPV based on a population-based survey in the 2003–2004 year, the total economic burden is estimated at approximately $109 million adjusted to the 2012 United States (U.S.) currency rate.

Results: Based on a prevalence of 255,267 women who were victims of IPV in the 2003–2004 year, the total economic burden is estimated at approximately $109 million adjusted to the 2012 the U.S. currency rate. The largest cost category contributing to the economic burden was the costs of healthcare services to treat injuries associated with IPV events.

Conclusion: The asymmetry between the economic burden of IPV and the amount of government resources devoted to IPV prevention efforts suggests the need for a greater role to be played by the government and other factors in society in the area of IPV prevention.

Sexual infidelity as trigger for intimate partner violence

BACKGROUND

We conducted a qualitative study to examine acute, situational factors and chronic stressors that triggered severe intimate partner violence (IPV) in women.

METHODS

Our sample consisted of 17 heterosexual couples, where the male was in detention for IPV and made telephone calls to his female victim. We used up to 4 hours of telephone conversational data for each couple to examine the couple's understanding of (1) acute triggers for the violent event and (2) chronic stressors that created the underlying context for violence. Grounded theory guided our robust, iterative data analysis involving audiotape review, narrative summation, and thematic organization.

RESULTS

Consistently across couples, violence was acutely triggered by accusations of infidelity, typically within the context of alcohol or drug use. Victims sustained significant injury, including severe head trauma (some resulting in hospitalization/surgery), bite wounds, strangulation complications, and lost pregnancy. Chronic relationship stressors evident across couples included ongoing anxiety about infidelity, preoccupation with heterosexual gender roles and religious expectations, drug and alcohol use, and mental health concerns (depression, anxiety, and suicide ideation/attempts).

CONCLUSIONS

Disseminated models feature jealousy as a strategy used by perpetrators to control IPV victims and as a red flag for homicidal behavior. Our findings significantly extend this notion by indicating that infidelity concerns, a specific form of jealousy, were the immediate trigger for both the acute violent episode and resulting injuries to victims and were persistently raised by both perpetrators and victims as an ongoing relationship stressor.

The health care costs of violence against women

The aim of this study is to analyze the health care costs of violence against women. For the study, we used a register-based approach where we identified victims of violence and assessed their actual health care costs at individual level in a bottom-up analysis. Furthermore, we identified a reference population. We computed the attributable costs, that is, the excess health care costs for victims compared to an identified reference population of nonvictims. Only costs within the health care sector were included, that is, somatic and psychiatric hospital costs, costs within the primary health care sector and costs of prescription pharmaceuticals. We estimated the attributable health care costs of violence against women in Denmark, using a generalized linear model where health care costs were modeled as a function of age, childbirth, and exposure to violence. In addition we tested whether socioeconomic status, multiple episodes of violence, and psychiatric contacts had any impact on health care costs. We found that the health care costs were about €1,800 higher for victims of violence than for nonvictims per year, driven mostly by higher psychiatric costs and multiple episodes of violence.

Prevalence of intimate partner violence among migrant and native women attending general practice and the association between intimate partner violence and depression

OBJECTIVE

To explore the prevalence of intimate partner violence (IPV) of women (aged >18 years) attending general practice and to assess the association between IPV and depression.

METHODS

A cross-sectional survey was conducted within 15 general practices across Rotterdam. The study population was all women older than 18 years of age attending general practice. Women were screened for sociodemographic factors, IPV and depression using the Composite Abuse Scale and the Beck Depression Inventory.

RESULTS

This study had a response rate of 63% (221 of 352 women). Two hundred and fourteen women were included in the study of whom 41% were migrants. Thirty per cent of the women attending general practise ever experienced IPV. Migrants experienced IPV 1.5 times more often compared to Dutch women. A significant association between IPV and depression was found. Half of the abused women were suffering from a depression. More than three-quarter of depressed women ever experienced IPV.

CONCLUSIONS

IPV is common in women attending general practice and it is significantly associated with depression. To improve recognition of abused women, doctors should ask depressed women if they ever experienced IPV.

Attributing selected costs to intimate partner violence in a sample of women who have left abusive partners: a social determinants of health approach

Selected costs associated with intimate partner violence were estimated for a community sample of 309 Canadian women who left abusive male partners on average 20 months previously. Total annual estimated costs of selected public- and private-sector expenditures attributable to violence were $13,162.39 per woman. This translates to a national annual cost of $6.9 billion for women aged 19–65 who have left abusive partners; $3.1 billion for those experiencing violence within the past three years. Results indicate that costs continue long after leaving, and call for recognition in policy that leaving does not coincide with ending violence.

A review of cost measures for the economic impact of domestic violence

Although economic analyses of domestic violence typically guide decisions concerning resource allocation, allowing policy makers to make better informed decisions on how to prioritize and allocate scarce resources, the methods adopted to calculate domestic violence costs have varied widely from study to study. In particular, only a few studies have reviewed the cost measures of the economic impact of domestic violence. This article reviews and compares these measures by covering approaches to categorizing costs, the cost components, and ways to estimate them and recommends an integrated framework that brings the various approaches together. Some issues still need to be addressed when further developing measures such as including omitted but significant measures and expanding the time horizons of others. The implications for future study of domestic violence costs are discussed.

Alcoholism and intimate partner violence: effects on children's psychosocial adjustment

It is widely recognized that alcoholism and relationship violence often have serious consequences for adults; however, children living with alcoholic parents are susceptible to the deleterious familial environments these caregivers frequently create. Given the prevalence of IPV among patients entering substance abuse treatment, coupled with the negative familial consequences associated with these types of behavior, this review explores what have been, to this point, two divergent lines of research: (a) the effects of parental alcoholism on children, and (b) the effects of children's exposure to intimate partner violence. In this article, the interrelationship between alcoholism and IPV is examined, with an emphasis on the developmental impact of these behaviors (individually and together) on children living in the home and offers recommendations for future research directions.

Examining the interface between substance misuse and intimate partner violence

There is considerable theoretical and empirical support for a link between substance misuse and perpetration and victimization of intimate partner violence. This review briefly summarizes this literature and highlights current research that addresses the interface between treatment for substance abuse and intimate partner violence. Suggestions for future research and clinical implications are provided.
