Traumatic Brain Injury Among Women Veterans: An Invisible Wound of Intimate Partner Violence

Exploring the Relationships Between Rehabilitation and Survivors of Intimate Partner Violence: A Scoping Review

Intimate partner violence (IPV) is a public health crisis affecting one in three women and one in ten men in their lifetimes. Rehabilitation professionals are highly likely to encounter survivors of IPV in their practice; yet, there exists no formal review assessing the relationship between IPV and rehabilitation. Our objective was to understand the types and contexts of rehabilitation care currently available for survivors of IPV, opportunities identified in the literature for rehabilitation care, and IPV awareness and education among rehabilitation providers. A search strategy related to IPV and four rehabilitation professionals of interest (occupational therapy, physiotherapy, speech-language pathology/therapy, and physiatry) was developed across 10 databases and complemented by a gray literature search. Two reviewers independently assessed articles for inclusion. In all, 44 articles met inclusion criteria, ranging from primary research articles (48%) to clinical newsletters. Included articles predominantly focused on opportunities for rehabilitation care (68%) and occupational therapists as a profession (68%). A minority of studies examined specific interventions for IPV survivors (18%) or assessed for knowledge and attitudes about IPV (16%) among rehabilitation professionals. To our knowledge, this is the first scoping review exploring the rehabilitation literature for IPV survivors. These findings show an awareness of IPV among rehabilitation professionals, the importance of identifying IPV in clients, and the ways in which rehabilitation professionals are uniquely situated to support survivors of IPV. There remains an opportunity to explore interventions designed specifically for IPV survivors.

IPV survivors' and service providers' perspectives on brain injury screening/evaluation process and impact

This study explores the perspectives of intimate partner violence (IPV) survivors and staff of brain injury (BI) screening, and the neuropsychological evaluation (NPE) process. We gathered qualitative data from 17 participants - 10 IPV survivors, at risk for a BI, who had received BI screening and a NPE and a total of 7 staff in IPV-serving organizations. Interviews were recorded, transcribed verbatim and analysed for key themes using thematic analysis. Survivors were over 18 years of age; the majority were between 19 and 45 years old, unemployed, unmarried, and had children. Survivors were angry, scared, and embarrassed to learn that they might have an IPV-related BI. They were thankful to have an explanation for some of their cognitive symptoms, which disrupted their daily activities, social relationships, and overall quality of life. Staff were pleased to be able to provide valuable information to their clients that could have a positive impact on their wellbeing. Overall, screening for a BI and participation in the NPE were well tolerated by IPV survivors with a possible BI. Inclusion of the perspectives of IPV survivors and support staff is an essential first step to better understanding their needs so interventions can be developed to aid their recovery.

Intimate Partner Violence and Other Trauma Exposures in Females With Traumatic Brain Injury

We examined whether females with a history of traumatic brain injury (TBI) and intimate partner violence (IPV) have greater exposure to lifetime trauma relative to females with TBI but no IPV history. Further, we assessed the effects of lifetime trauma on psychological outcomes after TBI. Female participants (n = 70; age M [standard deviation-SD] = 50.5 [15.2] years) with TBI (time since injury median [interquartile range -IQR] = 10.2 [5.3-17.8] years) completed a structured assessment of lifetime history of TBI, including an IPV module to query head injuries from physical violence by an intimate partner. We characterized lifetime trauma exposure with the Adverse Childhood Experiences (ACEs) questionnaire and Survey of Exposure to Community Violence (CV). We evaluated psychological functioning with self-report questionnaires of post-traumatic stress disorder (PTSD), depression, and anxiety symptoms. Compared with those with no IPV history (n = 51), participants reporting IPV-related head injuries (n = 19; 27.1%) reported more ACEs (M[SD] IPV: 4.5[2.9]; No IPV: 1.6[1.8], p < 0.001, d = 1.08) and greater CV (IPV: 17.5[8.4]; No IPV: 7.6[6.1], p < .0001, d = 1.26). Within the full sample, ACEs (β = 0.21, 95% confidence interval [CI] = 0.04-0.39) and CV (β = 0.07, 95% CI = 0.01-0.13) predicted worse PTSD symptoms, while IPV alone did not. Exposure to all three sources of trauma (ACEs, CV, and IPV) was associated with worse PTSD symptoms relative to fewer traumas. The results highlight the scope of traumatic exposures among TBI survivors and the importance of considering IPV and other lifetime trauma exposure in assessing and managing TBI. Trauma-informed interventions that are modified for TBI-related impairment may offer improved outcomes in managing psychological symptoms.

Head Injury Due to Intimate Partner Violence: Injury Characteristics, Subacute Symptoms, and Receipt of Care

Women survivors of intimate partner violence (IPV) have increased risk of repetitive neurotrauma in their lifetime but have received less research focus compared with populations of athletes, veterans, and emergency department patients. The current study examined the importance of IPV as a contextual mechanism of injury, by comparing women survivors of IPV based on whether they experienced a head injury due to IPV or a head injury not due to IPV. The analyses involved archival data from in-person interviews conducted with women who received a protective order against an intimate partner in Kentucky from 2001 to 2004 (n = 641). Women were excluded if they reported no head injury history (n = 268), resulting in two groups compared based on a retrospective cohort design: 255 women with at least one self-reported IPV-related head injury (M = 33.8 ± 9.0 years old, range: 19-65; 87.5% White) and 118 women with self-reported head injuries due to reasons other than IPV (M = 32.2 ± 9.1 years old, range: 18-62; 89.0% White). Participants were compared on injury characteristics, lifetime physical and sexual IPV severity, subacute symptoms of head injury, and receipt of care for head injury. Compared with women with head injuries unrelated to IPV, women with IPV-related head injuries reported a higher number of lifetime head injuries (Mdn[range]: IPV-related = 3[1-515] vs. non-IPV-related = 1[1-13], p < 0.001, r = 0.51) and a higher number of head injuries involving loss of consciousness (Mdn[range]: IPV-related = 1[1-35] vs. non-IPV-related = 1[1-4], p < 0.001, r = 0.27), but lower rates of hospitalization (IPV-related = 56.1% vs. non-IPV-related = 73.7%, p = 0.001, odds ratio [OR] = 2.20 [95% confidence interval (CI): 1.36, 3.55]) and formal rehabilitation (IPV-related = 3.2% vs. non-IPV-related = 9.4%, p = 0.011, OR = 3.18 [1.24, 8.13]) following head injury. Women with IPV-related head injuries had greater lifetime severity of physical IPV (p < 0.001, d = 0.64 [0.41, 0.86]) and sexual IPV (p < 0.001, d = 0.38 [0.16, 0.60]). Women with IPV-related head injuries endorsed all symptoms at greater rates than women with non-IPV-related head injuries (ps < 0.001), including physical (e.g., headaches: OR = 3.15 [1.81, 5.47]; dizziness: OR = 2.65 [1.68, 4.16]), cognitive (e.g., trouble problem solving: OR = 2.66 [1.53, 4.64]; inattention: OR = 2.39 [1.52, 3.78]), and emotional symptoms (e.g., depression: OR = 7.39 [4.48, 12.20]; anxiety: OR = 4.60 [2.82, 7.51]). The total count of symptoms endorsed was higher for women with IPV-related head injury than women with head injuries unrelated to IPV (p < 0.001, d = 0.71 [0.49, 0.94]). When controlling for lifetime physical and sexual IPV, IPV-related head injury was independently associated with symptom count (β = 0.261, p < 0.001) and accounted for additional variance in symptom count (ΔR2 = 0.06, p < 0.001). Among women survivors of IPV, those reporting IPV-related head injuries reported greater subacute symptoms, but a lower likelihood of being hospitalized or receiving rehabilitative care. Women with self-reported IPV-related head injuries represent an underserved population that is often unevaluated following injury and may have many unmet care needs. Future studies should examine persistent symptoms following IPV-related head injuries and interventions that would be most beneficial for this population.

Traumatic brain injury screening and neuropsychological functioning in women who experience intimate partner violence

Objective: The potential for traumatic brain injury (TBI) to occur as the result of intimate partner violence (IPV) has received increased interest in recent years. This study sought to investigate the possible occurrence of TBI in a group of women who survived IPV and to measure the specific profile of cognitive deficits using standardized neuropsychological measures. Method: A comprehensive questionnaire about abuse history; neuropsychological measures of attention, memory and executive functioning; and measures of depression, anxiety and post-traumatic stress disorder were given to women who were IPV survivors, women who were sexual assault (SA) survivors, and a comparison group of women who did not experience IPV or SA. Results: Overall, rates of potential TBI, as measured by the HELPS brain injury screening tool, were high and consistent with previous studies. Consistent with potential TBI, lower scores were demonstrated on measures of memory and executive functioning compared to survivors of SA or those not exposed to violence. Importantly, significant differences on measures of memory and executive functioning remained, after controlling for measures of emotion. Of note, cognitive changes were highest among women who experienced non-fatal strangulation (NFS) compared to IPV survivors who did not. Conclusions: Rates of TBI may be high in women who survive IPV, especially those who survive strangulation. Better screening measures and appropriate interventions are needed as well as larger studies that look at social factors associated with IPV.

In her own words: a phenomenological analysis of stories told by female service members and veterans after traumatic brain injury

PURPOSE

Given the majority of Service Members and Veterans (SMV) who have sustained a traumatic brain injury (TBI) are male, the female experience with TBI has not been captured in the general understanding of TBI. To improve understanding of the experience of female SMV after TBI utilizing a qualitative phenomenological approach on stories as told by female SMV.

MATERIALS AND METHODS

Ten female SMV participated in storytelling workshops and created video stories documenting their personal experience with TBI. Workshops were hosted by the VA Palo Alto Health Care System Polytrauma System of Care (VAPAHCS PSC). A grounded thematic analysis was conducted on the video stories.

RESULTS

Three common content themes emerged from all the stories: (1) negative psychological and emotional impacts of TBI, (2) acceptance and healing process associated with recovery, and (3) military contexts. Negative psychological and emotional impacts included intrapersonal impacts such as negative emotions, suicidal ideation, and dealing with cognitive and physical challenges, and interpersonal impacts in relationships and loss of independence. Notably, all the stories acknowledged an acceptance and healing process, characterized by several subthemes including motivational factors, TBI education, spirituality, and advocacy work. Lastly, each story mentioned military context, highlighting the unique experience within this population.

CONCLUSIONS

This phenomenological examination adds evidence-based understanding to the experience after TBI among female SMV. Each story uncovered nuanced and multifaceted issues that women experience in their TBI recovery. Our findings provide context to guide future intervention on the care, support, and TBI recovery for the female SMV population.

Diet's Impact on Post-Traumatic Brain Injury Depression: Exploring Neurodegeneration, Chronic Blood-Brain Barrier Destruction, and Glutamate Neurotoxicity Mechanisms

Traumatic brain injury (TBI) has a profound impact on cognitive and mental functioning, leading to lifelong impairment and significantly diminishing the quality of life for affected individuals. A healthy blood-brain barrier (BBB) plays a crucial role in guarding the brain against elevated levels of blood glutamate, making its permeability a vital aspect of glutamate regulation within the brain. Studies have shown the efficacy of reducing excess glutamate in the brain as a treatment for post-TBI depression, anxiety, and aggression. The purpose of this article is to evaluate the involvement of dietary glutamate in the development of depression after TBI. We performed a literature search to examine the effects of diets abundant in glutamate, which are common in Asian populations, when compared to diets low in glutamate, which are prevalent in Europe and America. We specifically explored these effects in the context of chronic BBB damage after TBI, which may initiate neurodegeneration and subsequently have an impact on depression through the mechanism of chronic glutamate neurotoxicity. A glutamate-rich diet leads to increased blood glutamate levels when contrasted with a glutamate-poor diet. Within the context of chronic BBB disruption, elevated blood glutamate levels translate to heightened brain glutamate concentrations, thereby intensifying neurodegeneration due to glutamate neurotoxicity.

Survey of depressive symptomatology in brain injury resulting from intimate partner violence

OBJECTIVE

A high prevalence of depression exists in specific sub-samples of survivors of brain injury (BI) sustained from intimate partner violence (IPV). However, the experience of depression by survivors of IPV-related BI from general civilian populations remains unclear. This study documents the symptom profile of depression reported by individuals who screened positive for sustaining an IPV-related BI.

METHODS

36 individuals who screened positive for possible IPV-related BI completed the Beck Depression Inventory-2^nd Edition (BDI-II). Subscales characterizing the nature of the symptoms were created. Frequency and descriptive statistics were calculated for item responses on the BDI-II. Participants were also assigned to high or low symptom severity groups to examine between-group differences.

RESULTS

Participants endorsed experiencing somatic symptoms more severely than self-evaluative and affective symptoms. Additionally, self-evaluative and cognitive symptoms correlated with total BDI-II scores for the high symptom severity group but not for the low symptom severity group.

CONCLUSIONS

The findings highlight somatic symptoms of depression, in particular as a common experience among survivors of IPV-related BI. Further, self-evaluative and cognitive symptoms may be more sensitive in detecting depression after IPV-related BI. These results may aid in the development of guidelines to better diagnose and treat depression in IPV-related BI.

Intimate partner violence, substance use, and health comorbidities among women: A narrative review

Exposure to intimate partner violence (IPV), including physical, sexual, and psychological violence, aggression, and/or stalking, impacts overall health and can have lasting mental and physical health consequences. Substance misuse is common among individuals exposed to IPV, and IPV-exposed women (IPV-EW) are at-risk for transitioning from substance misuse to substance use disorder (SUD) and demonstrate greater SUD symptom severity; this too can have lasting mental and physical health consequences. Moreover, brain injury is highly prevalent in IPV-EW and is also associated with risk of substance misuse and SUD. Substance misuse, mental health diagnoses, and brain injury, which are highly comorbid, can increase risk of revictimization. Determining the interaction between these factors on the health outcomes and quality of life of IPV-EW remains a critical need. This narrative review uses a multidisciplinary perspective to foster further discussion and research in this area by examining how substance use patterns can cloud identification of and treatment for brain injury and IPV. We draw on past research and the knowledge of our multidisciplinary team of researchers to provide recommendations to facilitate access to resources and treatment strategies and highlight intervention strategies capable of addressing the varied and complex needs of IPV-EW.

Exploring the intersection of brain injury and mental health in survivors of intimate partner violence: A scoping review

Rationale

Intimate partner violence (IPV) is the most commonly occurring form of violence against women. The most common site of injury in IPV is the head, face, and neck, resulting in possible brain injury (BI). Independently, mental health (MH) concerns are highly prevalent among both IPV survivors and individuals with BI; however, no systematic review exists on the combined experience of BI and MH in IPV.

Objective

The aim of this review was to describe the identification of and relationships between BI, MH, and IPV in the literature and the implications for health policy and practice.

Methods

A search strategy including text words and subject headings related to BI, IPV, and MH was developed for MEDLINE and translated to EMBASE, PsycINFO, CINAHL, Cochrane, Scopus, and Web of Science. Two reviewers independently assessed articles for inclusion. Articles discussing MH, BI, and IPV in relation to one another were included in the review.

Results

Twenty-eight articles were identified for inclusion. Methods for identifying IPV, BI, and MH were highly variable across studies. Fourteen studies reported significantly higher MH scores in IPV survivors with BI than in those without BI. Articles predominantly focused on cis gender women in heterosexual relationships and the impact of race and ethnicity were largely overlooked. Healthcare access was explored by eight articles, though none discussed the implications of co-occurring BI and MH.

Conclusion

Brain injury and MH are highly prevalent among IPV survivors; however, little research discusses the implication for healthcare. Future research should explore healthcare-related needs and experiences to inform policy and practice and better represent the diversity of IPV survivors.

Battered and Brain Injured: Traumatic Brain Injury Among Women Survivors of Intimate Partner Violence-A Scoping Review

OBJECTIVES

The objective of this scoping review is to examine the extent, range, and nature of literature targeting health-care professionals on the prevalence and outcome of intimate partner violence (IPV)-related traumatic brain injury (TBI). The purpose is to gain an understanding of prevalence, investigate screening tool use, generate IPV/TBI-specific support recommendations, and identify suggestions for future research.

METHOD

The review was guided by Arksey and O'Malley's five stages for conducting a scoping review. A comprehensive search of nine databases revealed 1,739 articles. In total, 42 published research papers that focused specifically on TBI secondary to IPV were included in the study.

SYNTHESIS

The literature reports inconsistencies in prevalence rates from IPV-related TBI. There are no current standardized screening practices in use, though the literature calls for a specialized tool. Frontline professionals would benefit from education on signs and symptoms of IPV-related TBI. Empirical studies are needed to generate reliable data on prevalence, experience, and needs of brain-injured survivors of TBI.

CONCLUSIONS

Findings from this study demonstrate the need for the development of an IPV-sensitive screening tool, more accurate data on prevalence, an interprofessional approach to care, and raised awareness and education on the diffuse symptoms of IPV-related TBI.

Sex and gender differences in mild traumatic brain injury/concussion

The high incidence of concussions/mild traumatic brain injury and the significant number of people with persisting concussion symptoms as well as the concern for delayed, neurodegenerative effects of concussions makes them a major public health concern. There is much to learn on concussions with respect to pathophysiology as well as vulnerability and resiliency factors. The heterogeneity in outcome after a concussion warrants a more personalized approach to better understand the biological and psychosocial factors that may affect outcome. In this chapter we address biological sex and gender as they impact different aspects of concussion including incidence, risk factors and outcome. As well, this chapter will provide a more fulsome overview of intimate partner violence, an often-overlooked cause of concussion in women. Applying the sex and gender lens to concussion/mild traumatic brain injury is imperative for discovery of its pathophysiology and moving closer to treatments.

An Injustice to the Justice-Involved: A Brief Report on the Impact of Traumatic Brain Injury on Incarcerated Mothers

Traumatic brain injury (TBI) is one of the leading causes of death and long-term disability among young adults worldwide and in the United States. TBIs are often associated with a high prevalence of morbidity, mortality, and other behavioral and cognitive problems. Several studies have shown that women living with TBIs have significantly higher odds of committing criminal acts, yet the impact of TBI on incarcerated women remains an underresearched area. By contrast, the effect of TBI on men is more prevalent in current literature, particularly relating to sports-related injuries. Given that an estimate of 80% of incarcerated women are mothers, we conducted a literature review in two phases focused on TBI in incarcerated mothers. The initial search of TBI in incarcerated mothers returned no results, so we proceeded in two phases. Phase 1 searched maternal outcomes of TBI, using the terms "maternal health" and "traumatic brain injury," whereas Phase 2 searched "traumatic brain injury" and "incarcerated women." Because so little information is available regarding TBI in incarcerated mothers, we used what we could find in these two phases to highlight the scarcity of knowledge about this population. This brief report addresses the knowledge gap that exists for incarcerated mothers living with TBI to encourage regular TBI screening to raise awareness and advocate for accommodated care. Correctional forensic nurses are perfectly placed to do TBI screening and to provide continuous rehabilitation after release to prevent reoffending.

Advanced brain age in deployment-related traumatic brain injury: A LIMBIC-CENC neuroimaging study

OBJECTIVE

To determine if history of mild traumatic brain injury (mTBI) is associated with advanced or accelerated brain aging among the United States (US) military Service Members and Veterans.

METHODS

Eight hundred and twenty-two participants (mean age = 40.4 years, 714 male/108 female) underwent MRI sessions at eight sites across the US. Two hundred and one participants completed a follow-up scan between five months and four years later. Predicted brain ages were calculated using T1-weighted MRIs and then compared with chronological ages to generate an Age Deviation Score for cross-sectional analyses and an Interval Deviation Score for longitudinal analyses. Participants also completed a neuropsychological battery, including measures of both cognitive functioning and psychological health.

RESULT

In cross-sectional analyses, males with a history of deployment-related mTBI showed advanced brain age compared to those without (t(884) = 2.1, p = .038), while this association was not significant in females. In follow-up analyses of the male participants, severity of posttraumatic stress disorder (PTSD), depression symptoms, and alcohol misuse were also associated with advanced brain age.

CONCLUSION

History of deployment-related mTBI, severity of PTSD and depression symptoms, and alcohol misuse are associated with advanced brain aging in male US military Service Members and Veterans.

Prevalence and Perception of Intimate Partner Violence-Related Traumatic Brain Injury

BACKGROUND

Traumatic brain injury (TBI) is a serious and often undiagnosed consequence of intimate partner violence (IPV). Data on prevalence of TBI among IPV survivors are emerging, but prevalence of IPV among patients presenting to TBI clinics is unknown. Identification of IPV is important to ensure patients with TBI receive appropriate intervention and referrals.

OBJECTIVE

To determine the proportion of women 18 years and older presenting to an acquired brain injury (ABI) clinic with confirmed or suspected concussion who reported experiencing IPV in the last 12 months or their lifetime.

METHODS

Single-center cross-sectional cohort study. Proportion of IPV-related TBI or head, neck, or facial) injuries were determined using a modified HELPS Brain Injury Screening Tool and the Neurobehavioral Symptom Inventory.

RESULTS

Of the 97 women approached, 50 were enrolled in the study. The average age was 46.1 years and 32 women (64.0%) reported a relationship history with a violent partner; 12-month prevalence of IPV was 26.5% and lifetime prevalence was 44.0%. Within their lifetime, all (44.0%) who reported an IPV history reported emotional abuse, 24.0% reported physical abuse, and 18.0% sexual abuse. HELPS responses indicated a high potential of lifetime IPV-related TBI for 29.2%, most commonly from being hit in the face or head (20.8%).

CONCLUSION

Implementation of IPV screening in community-based ABI clinics is a pivotal step toward understanding the potential scope of TBI and addressing the wide range of somatic, cognitive, and affective symptoms experienced by IPV survivors. IPV screening also will lead to timely referral and follow-up and increase patient safety after discharge from rehabilitation.

Longitudinal Analysis of Persistent Postconcussion Symptoms, Probable TBI, and Intimate Partner Violence Perpetration Among Veterans

OBJECTIVE

To determine veterans' intimate partner violence (IPV) perpetration following report of traumatic brain injury (TBI) and persistent postconcussion symptoms (PPCSs).

SETTING

Five Department of Veterans Affairs (VA) medical centers.

PARTICIPANTS

Veterans with nonmissing data on main measures, resulting in N = 1150 at baseline and N = 827 at follow-up.

DESIGN

Prospective cohort study with secondary data analysis of self-reported TBI, PPCSs, and IPV perpetration, controlling for common predictors of IPV, including binge drinking, marijuana use, pain intensity, and probable posttraumatic stress disorder.

MAIN MEASURES

VA TBI Screening Tool to assess for probable TBI and PPCSs; Conflict Tactics Scale-Revised (CTS-2S) to assess for IPV perpetration.

RESULTS

Almost half (48%) of participants reported IPV perpetration at follow-up. Both probable TBI and higher PPCSs at baseline were associated with overall IPV perpetration and more frequent IPV perpetration at follow-up. Only PPCSs significantly predicted IPV perpetration after controlling for common predictors of IPV perpetration. Neither probably TBI nor PPCSs predicted frequency of IPV perpetration.

CONCLUSION

When considered alongside common risk factors for IPV perpetration, PPCS was uniquely associated with the likelihood of IPV perpetration in this veteran sample. Given post-9/11 veterans' elevated risk for head injury, findings emphasize the distinctive value of PPCSs in understanding risk for IPV perpetration. We recommend increased assessment for PPCSs in clinical practice among veterans enrolled in VA care and highlight several important areas for future research and intervention development.

The Intersection of Intimate Partner Violence and Traumatic Brain Injury: Findings From an Emergency Summit Addressing System-Level Changes to Better Support Women Survivors

BACKGROUND

Traumatic brain injury (TBI) occurring during intimate partner violence (IPV) is a largely unrecognized but significant public health crisis. One in 3 women will experience IPV in their lifetime, up to 75% of whom will sustain a TBI as a result. This article reports on the systems-level findings from a national summit to address barriers, needs, and priorities related to healthcare and support services for women survivors of IPV-TBI.

OBJECTIVES

(1) To identify key needs, facilitators, and barriers to care for women survivors of IPV presenting with TBI; and (2) to cocreate ideas for resources and principles for identification, clinical care, and support for healthcare practitioners who treat women exposed to IPV and TBI.

METHODS

Using a community-based participatory research approach, we engaged 30 stakeholders-drawn from a national IPV-TBI Knowledge-to-Practice (K2P) Network including diverse women survivors, service providers, researchers, and decision makers-in 2 half-day virtual meetings. Data were gathered through small group breakout sessions using semistructured discussion guides. Sessions were recorded, transcribed verbatim, and analyzed using thematic analysis techniques. Stakeholders contributed to the analysis and knowledge translation through member-checking activities. Ethics approval was obtained through the University of Toronto.

FINDINGS

Three main systems-level themes arose during these discussions: (1) the need for trauma-informed, anti-racist, and equitable health and social care systems; (2) the need for cross-pollination of knowledge between disciplines; and (3) the need for systems-level support for integrated and coordinated care. This article explores these needs and provides recommendations and suggestions for paths forward.

CONCLUSIONS

The findings of this project enhance understanding of system-level needs among women survivors and provide a template for a national agenda for IPV-TBI research and practice.

Traumatic Brain Injury Screening and the Unmet Health Needs of Shelter-Seeking Women with Head Injuries Related to Intimate Partner Violence

Background: Unmet health needs of women with head injuries sustained by intimate partner violence (IPV) include risk of traumatic brain injury (TBI). The purpose of this evaluation was to explore the potential effectiveness of TBI screening as a health promotion strategy for shelter-seeking women with IPV head injuries. We wanted to learn if shelter-seeking women, willing to disclose IPV, would accept TBI screening if offered.

Methods: An extended version of the HELPS TBI screening tool and survey of daily symptoms and health needs were used to screen new residents of an urban shelter for women.

Results: The participants (N = 18) primarily were educated black women with one or more self-reported IPV-related head injury. Most participants (77.8%) had positive TBI screens for probable brain injury. The majority (88.8%) lived with one or more daily symptoms they did not have before sustaining a IPV head injury. The symptoms reported most frequently were depression (88.9%), anxiety (77.8%), and headache (66.7%). All participants had one or more unmet health need. Although most (77.8%) needed to see a primary care provider, mental health care was the most important health need identified.

Conclusions: TBI screening could be considered an effective health promotion strategy for IPV survivors if screening facilitates treatment for positive screens and other unmet health needs. Further research is needed to properly assess this.

Brain Injury and Mental Health Among the Victims of Intimate Partner Violence: A Case-Series Exploratory Study

Intimate partner violence (IPV) survivors frequently report face, head, and neck as their injury site. Many mild traumatic brain injuries (TBIs) are undiagnosed or underreported among IPV survivors while these injuries may be linked to changes in brain function or pathology. TBI sustained due to IPV often occurs over time and ranges in severity. The aim of this case-series study was to explore risk factors, symptoms, and brain changes unique to survivors of intimate partner violence with suspicion of TBI. This case-series exploratory study examines the potential relationships among IPV, mental health issues, and TBI. Participants of this study included six women: 3 women with a history of IPV without any experience of concussive blunt force to the head, and 3 women with a history of IPV with concussive head trauma. Participants completed 7T MRI of the brain, self-report psychological questionnaires regarding their mental health, relationships, and IPV, and the Structured Clinical Interview. MRI scans were analyzed for cerebral hemorrhage, white matter disturbance, and cortical thinning. Results indicated significant differences in resting-state connectivity among survivors of partner violence as well as differences in relationship dynamics and mental health symptoms. White matter hyperintensities are also observed among the survivors. Developing guidelines and recommendations for TBI-risk screening, referrals, and appropriate service provision is crucial for the effective treatment of TBI-associated IPV. Early and accurate characterization of TBI in survivors of IPV may relieve certain neuropsychological consequences.

Impacts of Male Intimate Partner Violence on Women: A Life Course Perspective

The nature and extent of the impacts of intimate partner violence (IPV) on victims are well documented, particularly male partner violence against women. However, less is known about how these impacts might change over time, including their legacy after women leave an abusive relationship and the lasting effects in their later lives. The purpose of this study was to examine women’s experiences of IPV at different stages over their life courses. Interviews with a cohort of 18 older women who had left an abusive relationship were analysed using thematic narrative analysis and the findings were presented according to trajectories, transitions, and turning points over their life courses. When in the relationship, the women experienced direct impacts on their physical, mental, social, and financial wellbeing. During separation, many experienced continued abuse and housing, legal, and financial stress. Life after separation was marked by loneliness, trauma, financial insecurity, and damaged relationships. Some women reached a turning point in their recovery through helping others. Understanding these impacts can inform interventions during each stage. Crisis support is critical when women are in an abusive relationship and during the dangerous phase of separation. Interventions can also assist women’s longer-term wellbeing and help them recover through post-traumatic growth.

A global collaboration to study intimate partner violence-related head trauma: The ENIGMA consortium IPV working group

Intimate partner violence includes psychological aggression, physical violence, sexual violence, and stalking from a current or former intimate partner. Past research suggests that exposure to intimate partner violence can impact cognitive and psychological functioning, as well as neurological outcomes. These seem to be compounded in those who suffer a brain injury as a result of trauma to the head, neck or body due to physical and/or sexual violence. However, our understanding of the neurobehavioral and neurobiological effects of head trauma in this population is limited due to factors including difficulty in accessing/recruiting participants, heterogeneity of samples, and premorbid and comorbid factors that impact outcomes. Thus, the goal of the Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium Intimate Partner Violence Working Group is to develop a global collaboration that includes researchers, clinicians, and other key community stakeholders. Participation in the working group can include collecting harmonized data, providing data for meta- and mega-analysis across sites, or stakeholder insight on key clinical research questions, promoting safety, participant recruitment and referral to support services. Further, to facilitate the mega-analysis of data across sites within the working group, we provide suggestions for behavioral surveys, cognitive tests, neuroimaging parameters, and genetics that could be used by investigators in the early stages of study design. We anticipate that the harmonization of measures across sites within the working group prior to data collection could increase the statistical power in characterizing how intimate partner violence-related head trauma impacts long-term physical, cognitive, and psychological health.

A Multi-Method Approach to a Comprehensive Examination of the Psychiatric and Neurological Consequences of Intimate Partner Violence in Women: A Methodology Protocol

The number of women in the United States that experience blows to the head during assaults by intimate partners is substantial. The number of head blows that result in a traumatic brain injury (TBI) is virtually unknown, but estimates far exceed numbers of TBI in parallel populations (e.g., blast exposure, accidents, sports) combined. Research on the impact of TBI on post-traumatic stress disorder (PTSD) in survivors of intimate partner violence (IPV) is sparse. This methodology paper describes the comprehensive, multi-method approach used by a multi-disciplinary team of investigators from several different fields of expertise to assess the interaction of psychiatric, cognitive, psychological, and physical conditions that result from IPV. Using state-of-the-art instruments, a comprehensive assessment of lifetime trauma exposure, lifetime history of TBI, psychiatric history, and a full assessment of current cognitive, neuropsychological and biomedical function was conducted with 51 female survivors of IPV who screened positive for PTSD. This multi-method assessment included clinician-administered diagnostic interviews modified to specifically assess the sequelae of IPV, standardized self-report surveys, neuropsychological tests, structural, diffusion, and functional neuroimaging and blood-based biomarkers. The specific details and full report of the results of the full study are beyond the scope of this methodology paper. Descriptive characteristics of the complex clinical presentation observed in this unique sample are described. The sample reported high rates of trauma exposure across the lifespan and 80% met full criteria for current PTSD. Women also reported high rates of lifetime subconcussive head injury (88.2%) and TBI (52.9%) from various etiologies (35.3% secondary to IPV). Descriptive findings from the methodological protocol described here have begun to reveal information that will advance our understanding of the impact of subconcussive head injury and TBI on recovery from mental injury among IPV survivors.

Understanding Traumatic Brain Injury in Females: A State-of-the-Art Summary and Future Directions

In this report, we identify existing issues and challenges related to research on traumatic brain injury (TBI) in females and provide future directions for research. In 2017, the National Institutes of Health, in partnership with the Center for Neuroscience and Regenerative Medicine and the Defense and Veterans Brain Injury Center, hosted a workshop that focused on the unique challenges facing researchers, clinicians, patients, and other stakeholders regarding TBI in women. The goal of this "Understanding TBI in Women" workshop was to bring together researchers and clinicians to identify knowledge gaps, best practices, and target populations in research on females and/or sex differences within the field of TBI. The workshop, and the current literature, clearly highlighted that females have been underrepresented in TBI studies and clinical trials and have often been excluded (or ovariectomized) in preclinical studies. Such an absence in research on females has led to an incomplete, and perhaps inaccurate, understanding of TBI in females. The presentations and discussions centered on the existing knowledge regarding sex differences in TBI research and how these differences could be incorporated in preclinical and clinical efforts going forward. Now, a little over 2 years later, we summarize the issues and state of the science that emerged from the "Understanding TBI in Women" workshop while incorporating updates where they exist. Overall, despite some progress, there remains an abundance of research focused on males and relatively little explicitly on females.

Acquired Brain Injury in the Context of Family Violence: A Systematic Scoping Review of Incidence, Prevalence, and Contributing Factors

Brain injury is often a precursor to, or result of, family violence. Yet there is little research identifying the connection of these two phenomena. The health cost (personal or societal) of brain injury within the family violence context is difficult to ascertain. Family violence can lead to lifelong psychological or physical scars and even death. A systematic review was conducted over three databases using Medical Subject Heading terms to investigate incidence, prevalence, and contributing factors of brain injury within a family violence context. Inclusion criteria were primary studies, any person who experienced traumatic brain injury in a familial context. Seven hundred and seven studies of varied designs were initially identified with 43 meeting inclusion criteria. Data were extracted and a deductive narrative synthesis was performed. The accuracy and generalizability of incidence and prevalence statistics was hindered by underreporting of family violence and the specificity of some of the population groups (e.g., female inmates). The factors contributing to brain injury within the family violence context had multifactorial causation and varied greatly across the populations studied. Five social determinants of health were identified: biological, behavioral, structural, social, and environmental. These factors included age and gender of parent/baby, crying as an antecedent of family violence, previous exposure to abuse as a child, hostile living environments, previous trauma, financial pressures, employment status, housing availability, and exposure to natural disasters. Future investigation into the nexus between brain injury and family violence is required; however, this is complicated due to global inconsistency of definitions, assessment tools, and research methods used.

Behavioral responses following repeated bilateral frontal region closed head impacts and fear conditioning in male and female mice

The frontal lobes are among the most vulnerable sites in traumatic brain injuries. In the current study, a balanced 2 × 2 × 2 design (n = 18 mice/group), female and male C57Bl/6J mice received repeated bilateral frontal concussive brain injury (frCBI) and underwent fear conditioning (FC) to assess how injured mice respond to adverse conditions. Shocks received during FC impacted behavior on all subsequent tests except the tail suspension test. FC resulted in more freezing behavior in all mice that received foot shocks when evaluated in subsequent context and cue tests and induced hypoactivity in the open field (OF) and elevated zero maze (EZM). Mice that sustained frCBI learned the FC association between tone and shock. Injured mice froze less than sham controls during context and cue tests, which could indicate memory impairment, but could also suggest that frCBI resulted in hyperactivity that overrode the rodent's natural freezing response to threat, as injured mice were also more active in the OF and EZM. There were notable sex differences, where female mice exhibited more freezing behavior than male mice during FC context and cue tests. The findings suggest frCBI impaired, but did not eliminate, FC retention and resulted in an overall increase in general activity. The injury was characterized pathologically by increased inflammation (CD11b staining) in cortical regions underlying the injury site and in the optic tracts. The performance of male and female mice after injury suggested the complexity of possible sex differences for neuropsychiatric symptoms.

Sex-Dependent Pathology in the HPA Axis at a Sub-acute Period After Experimental Traumatic Brain Injury

Over 2.8 million traumatic brain injuries (TBIs) are reported in the United States annually, of which, over 75% are mild TBIs with diffuse axonal injury (DAI) as the primary pathology. TBI instigates a stress response that stimulates the hypothalamic-pituitary-adrenal (HPA) axis concurrently with DAI in brain regions responsible for feedback regulation. While the incidence of affective symptoms is high in both men and women, presentation is more prevalent and severe in women. Few studies have longitudinally evaluated the etiology underlying late-onset affective symptoms after mild TBI and even fewer have included females in the experimental design. In the experimental TBI model employed in this study, evidence of chronic HPA dysregulation has been reported at 2 months post-injury in male rats, with peak neuropathology in other regions of the brain at 7 days post-injury (DPI). We predicted that mechanisms leading to dysregulation of the HPA axis in male and female rats would be most evident at 7 DPI, the sub-acute time point. Young adult age-matched male and naturally cycling female Sprague Dawley rats were subjected to midline fluid percussion injury (mFPI) or sham surgery. Corticotropin releasing hormone, gliosis, and glucocorticoid receptor (GR) levels were evaluated in the hypothalamus and hippocampus, along with baseline plasma adrenocorticotropic hormone (ACTH) and adrenal gland weights. Microglial response in the paraventricular nucleus of the hypothalamus indicated mild neuroinflammation in males compared to sex-matched shams, but not females. Evidence of microglia activation in the dentate gyrus of the hippocampus was robust in both sexes compared with uninjured shams and there was evidence of a significant interaction between sex and injury regarding microglial cell count. GFAP intensity and astrocyte numbers increased as a function of injury, indicative of astrocytosis. GR protein levels were elevated 30% in the hippocampus of females in comparison to sex-matched shams. These data indicate sex-differences in sub-acute pathophysiology following DAI that precede late-onset HPA axis dysregulation. Further understanding of the etiology leading up to late-onset HPA axis dysregulation following DAI could identify targets to stabilize feedback, attenuate symptoms, and improve efficacy of rehabilitation and overall recovery.

Prevalence of Self-Reported Intimate Partner Violence Victimization Among Military Personnel: A Systematic Review and Meta-Analysis

BACKGROUND

Research on intimate partner violence (IPV) in the military has tended to focus on military personnel as perpetrators and civilian partners/spouses as victims. However, studies have found high levels of IPV victimization among military personnel. This article systematically reviews studies of the prevalence of self-reported IPV victimization among military populations.

METHODS

Searches of four electronic databases (Embase, Medline, PsycINFO, and Web of Science) were supplemented by reference list screening. Meta-analyses of the available data were performed, where possible, using the random effects model.

RESULTS

This review included 28 studies with a combined sample of 69,808 military participants. Overall, similar or higher prevalence rates of physical IPV victimization were found among males compared to females and this was supported by a meta-analytic subgroup analysis: pooled prevalence of 21% (95% confidence interval [CI] = [17.4, 24.6]) among males and 13.6% among females (95% CI [9.5, 17.7]). Psychological IPV was the most prevalent type of abuse, in keeping with findings from the general population. There were no studies on sexual IPV victimization among male personnel. Evidence for the impact of military factors, such as deployment or rank, on IPV victimization was conflicting.

DISCUSSION

Prevalence rates varied widely, influenced by methodological variation among studies. The review highlighted the lack of research into male IPV victimization in the military and the relative absence of research into impact of IPV. It is recommended that future research disaggregates results by gender and considers the impact of IPV, in order that gender differences can be uncovered.

Intimate Partner Violence Among Female OEF/OIF/OND Veterans Who Were Evaluated for Traumatic Brain Injury in the Veterans Health Administration: A Preliminary Investigation

Many female veterans have deployed to Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND), and some experience traumatic brain injury (TBI). Although TBI is increasingly recognized as an important health issue for female OEF/OIF/OND veterans, there is little attention to stressful experiences that may exacerbate health problems or hinder recovery among veterans who may have experienced TBI. Lifetime intimate partner violence (IPV) is common among general samples of female veterans. Given the negative implications of IPV on women's health, it is important to understand whether there is a relationship between lifetime IPV and health functioning among female veterans who have experienced possible TBI. This study provides an exploration of lifetime IPV and its associations with physical and mental health, as well as community reintegration, among female OEF/OIF/OND veterans who have been evaluated for TBI. The sample comprised 127 female veterans who participated in a larger study that examined reintegration among OEF/OIF/OND veterans who received a TBI evaluation in the Veterans Heath Administration (VHA) and completed an assessment of lifetime IPV. Primary and secondary data sources included survey responses (e.g., health symptoms and reintegration) and VHA administrative data (e.g., health diagnoses). Results indicated that nearly two thirds (63.0%) of women who completed a TBI evaluation reported lifetime IPV, though clinician-confirmed TBI was not associated with IPV. Women who experienced IPV, compared with those who did not, reported higher levels of neurobehavioral symptoms and were significantly more likely to have diagnoses of back pain (48.6% vs. 30.0%, respectively) and substance abuse (12.2% vs. 0%, respectively). Notwithstanding, women with and without lifetime IPV reported similar levels of reintegration. Findings provide evidence that lifetime IPV may be common among female OEF/OIF/OND veterans who are evaluated for TBI, and that IPV is associated with several treatable health problems among this population.

Characterizing the Risk of Depression Following Mild Traumatic Brain Injury: A Meta-Analysis of the Literature Comparing Chronic mTBI to Non-mTBI Populations

Objective: Mild traumatic brain injury (mTBI) is associated with depressed mood acutely post-injury, but there is little evidence regarding long-term depression. The aim of this study was to determine the odds ratio (OR) of depression chronically following mTBI.

Methods: We searched Medline (PubMed), ProQuest, and Web of Science from date of database creation to January 23, 2019, for eligible studies examining depression at least 6 months post-injury in adult subjects with mTBI of any etiology, including civilians and military. Three authors independently reviewed titles and abstracts for study eligibility. Data were extracted and collated by two investigators. Risk of bias was assessed with the SIGN methodology. Study data were pooled using random-effects meta-analysis. The primary exposure was mTBI, and the primary outcome was depression. Secondary exploratory variables were time of assessment, age at injury, age at assessment, sex, and etiology.

Results: We included 47 cross-sectional studies (n = 25,103 mTBI and 29,982 control), 26 cohort studies (n = 70,119 mTBI, 262,034 control), four prospective observational studies (n = 1,058 mTBI and 733 control), two prospective longitudinal studies (n = 119 mTBI, 81 control), two case-control studies (n = 56 mTBI, 56 control), and one randomized controlled trial (n = 252 mTBI, 3,214 control). mTBI was associated with a 3.29-fold increased risk of depression (OR 3.29, 95% CI 2.68–4.03, I² = 96%). The OR for depression did not change when subjects were assessed at 6–12 months (OR 2.43, 1.45–4.07), years 1–2 (OR 4.12, 2.10–8.07); 2–10 (OR 3.28, 2.42–4.46), or 10+ (OR 3.42, 1.51–7.77). Similar risk of depression was sustained across different age at injury (<25: OR 2.26, 1.82–2.81; 25–35: OR 4.67, 3.06–7.14; >35: OR 2.69, 1.42–5.10) and different age at assessment (<40 years: OR 3.14, 2.48–3.99; >40 years: OR 4.57, 2.54–8.24). Female sex had a non-significant increase in OR (OR 19.97, 2.39–166.93) compared to male (OR 3.0, 2.33–3.86). mTBI etiology had no impact on depression.

Conclusions: Those experiencing mTBI are more than three times more likely to experience depression compared to those without a history of mTBI, and this risk remains decades beyond the mTBI event. Future longitudinal studies are needed to identify and mitigate this risk.

Traumatic brain injury among female veterans: a review of sex differences in military neurosurgery

The impact of traumatic brain injury (TBI) has been demonstrated in various studies with respect to prevalence, morbidity, and mortality data. Many of the patients burdened with long-term sequelae of TBI are veterans. Although fewer in number, female veterans with TBI have been suggested to suffer from unique physical, mental, and social challenges. However, there remains a significant knowledge gap in the sex differences in TBI. Increased female representation in the military heralds an increased risk of TBI for female soldiers, and medical professionals must be prepared to address the unique health challenges in the face of changing demographics among the veteran TBI population. In this review, the authors aimed to present the current understanding of sex differences in TBI in the veteran population and suggest directions for future investigations.

Gender Differences in Outcomes after Traumatic Brain Injury among Service Members and Veterans

This scoping study describes the range of outcomes in traumatic brain injury (TBI) studies of military service members and veterans addressing gender differences. A secondary purpose is to identify differences in outcomes between male and female participants in such studies. We searched PubMed, CiNAHL, and PsycInfo databases for relevant articles. Two reviewers independently screened results. Of 822 unique titles and abstracts screened for eligibility, 55 full articles were reviewed, with 29 studies meeting full inclusion criteria. Twenty of the 29 included studies used retrospective designs and all but two used data collected from Veterans Affairs or Department of Defense health care settings. TBI was diagnosed by self-report, screening, and evaluation procedures, and medical record documentation. Ten different outcome categories were identified among the included studies. In general, female service members and veterans have not been well represented in TBI outcomes research. Evidence suggests that female veterans with mild TBI (mTBI) report more neurobehavioral symptoms and use more outpatient services than male veterans. Studies also indicate that female veterans with TBI are more frequently diagnosed with depression. Additional research is essential to support precision treatment recommendations for female veterans with TBI, as women represent a growing proportion of the patients served by the Veterans Health Administration. LEVEL OF EVIDENCE: IV.

Blast-Related Traumatic Brain Injury: Current Concepts and Research Considerations

Traumatic brain injury (TBI) is a well-known consequence of participation in activities such as military combat or collision sports. But the wide variability in eliciting circumstances and injury severities makes the study of TBI as a uniform disease state impossible. Military Service members are under additional, unique threats such as exposure to explosive blast and its unique effects on the body. This review is aimed toward TBI researchers, as it covers important concepts and considerations for studying blast-induced head trauma. These include the comparability of blast-induced head trauma to other mechanisms of TBI, whether blast overpressure induces measureable biomarkers, and whether a biodosimeter can link blast exposure to health outcomes, using acute radiation exposure as a corollary. This examination is contextualized by the understanding of concussive events and their psychological effects throughout the past century's wars, as well as the variables that predict sustaining a TBI and those that precipitate or exacerbate psychological conditions.

Practitioner perspectives on the nexus between acquired brain injury and family violence

Family violence has been highlighted by the World Health Organization as a major public health concern. Although family violence occurs to all genders, a higher prevalence of victims are female. Estimates report around 30% of all women experience intimate partner violence worldwide. Experiencing assault in the family violence context can lead to an acquired brain injury (ABI); however, the connection between these two phenomena has not been well established. The aim of this qualitative study was to explore the extent of, and factors contributing to, ABI and family violence. We conducted 22 semi-structured interviews and one focus group (n = 4) with practitioners working with family violence victims and/or perpetrators. Thematic data analysis utilised inductive and deductive coding approaches. The Social Determinants of Health Framework was used to guide analysis. Practitioners estimated 30%-40% of the clients on their caseloads had a suspected or diagnosed ABI. They identified that contributing factors were extremely complex. These included acquiring an ABI through assault (past family violence or other criminal act), and transport crashes. Complicating factors of ABI were identified as mental health conditions, alcohol and drug use, and post-traumatic stress disorder. Additional factors contributing to family violence were recognised as biological (age of parent, twin births, pregnancy, premature births, and children with congenital abnormalities), relationships (intimate partner, father, boyfriend, mother and siblings), previous trauma (family violence), and life stressors (unemployment, financial, and lack of housing). Social determinants of health included cultural (ethnicity, societal attitudes, values, and beliefs) and organisational (legislation and policy) factors which influenced behaviours and outcomes across all sectors. A model of Brain injury Family violence Nexus (BFN) was created to understand the interaction between these phenomena. Utilising the BFN model to understand the interaction can enhance the methods used within health and social services for a more efficacious approach.

Associations between traumatic brain injury from intimate partner violence and future psychosocial health risks in women

OBJECTIVE

The effects of traumatic brain injury (TBI) incurred during military service are widely studied; however, less is known about TBI resulting from intimate partner violence ("IPV-related TBI"). Women Veterans are at high risk for IPV, yet no research has examined future psychosocial health risks associated with IPV-related TBI history in this population.

METHODS

We examined psychiatric and physical health outcomes, as well as IPV, in a sample of women Veterans who, at Time 1, reported IPV-related TBI with (n = 13) or without (n = 20) persistent symptoms; that is, symptoms such as memory problems, balance problems or dizziness, sensitivity to bright light, irritability, headaches, and sleep problems that began or got worse immediately following the IPV-related TBI and occurred within the past week. These women completed web-based surveys 18 months later (Time 2), which included validated measures of psychiatric and physical health symptoms as well as past-year IPV. We conducted linear regressions to model whether T1 IPV-related TBI with persistent symptoms predicted worse health outcomes at T2, in comparison to T1 IPV-related without persistent symptoms.

RESULTS

Controlling for significant covariates (i.e., military sexual trauma; MST), IPV-related TBI with persistent symptoms at Time 1 was associated with significantly worse outcomes at Time 2 across all health outcome domains (sr² range: 0.12-0.37). After controlling for MST and probable posttraumatic stress disorder (PTSD) at Time 1, IPV-related TBI with persistent symptoms at Time 1 remained significantly associated with worse Time 2 symptoms of insomnia, depression, and physical health (sr² range: 0.12-0.25).

CONCLUSION

Women who experience IPV-related TBI with persistent symptoms are at higher risk for worse psychosocial health outcomes 18 months later. Findings necessitate screening IPV survivors for TBI with persistent symptoms and tailoring TBI and psychosocial interventions to reduce risk for ongoing health sequelae.

The Effect of Intimate Partner Violence and Probable Traumatic Brain Injury on Mental Health Outcomes for Black Women

Severe intimate partner violence (IPV) including loss of consciousness from head injuries and/or strangulation can result in traumatic brain injury (TBI), a brain pathology characterized by altered brain function, cognitive impairment, and mental health disorders, including depression and posttraumatic stress disorder (PTSD). This study examines the prevalence of probable TBI (defined as loss of consciousness from a blow to the head and/or strangulation) and its association with comorbid PTSD and depression among Black women, who experience both higher rates of IPV and greater mental health burden than White and Latina women. Data come from a retrospective cohort study of 95 Black women with abuse history including IPV, forced sex, and childhood maltreatment. About one-third of women (n=32) had probable TBI. Among them, 38% (n=12) were hit on the head, 38% (n=12) were strangled to unconsciousness, and 25% (n=8) were strangled and hit on the head. Women with IPV history and probable TBI had significantly greater odds of various physical injuries including those that required medical care compared to other abused women. Probable TBI significantly increased comorbid PTSD and depression by 8.93 points (SE=3.40), after controlling for past violence (F _{(4, 90)}=3.67, p<.01). Findings from this study reinforce the need to screen women who lost unconsciousness due to IPV for TBI and facilitate referrals to IPV interventions and mental health treatment.

Extreme Control and Instability: Insight Into Head Injury From Intimate Partner Violence

AIM

The aim of this study was to understand the social context of the lives of women who experienced a head injury from intimate partner violence.

BACKGROUND

Sixty percent to 92% of survivors of intimate partner violence receive head trauma during the abuse. Little research exists regarding the episodes of abuse when women receive a head injury, or the reasons women might not seek medical care for the head injury or the abuse.

METHOD

Twenty-one interviews from nine women who self-reported passing out from being hit in the head were analyzed using thematic analysis.

FINDINGS

Themes of extreme control and manipulation from abusers emerged, and women described living with instability from cycles of incarceration, drug and alcohol use, and fear of losing their children. Women did not receive medical care for head injury because the abusers often used forced sex immediately after the head injury to instill fear and authority.

IMPLICATIONS FOR FORENSIC NURSING

Hitting women in the head is not only about physical abuse, but also about exerting dominance and creating an environment of extreme control. Forensic nurses are uniquely positioned to screen for head injuries during initial assessments and follow-up visits and connect women with appropriate resources.

Living in Fear and Prioritizing Safety: Exploring Women's Lives After Traumatic Brain Injury From Intimate Partner Violence

There is increasing evidence that women are receiving a traumatic brain injury (TBI) during episodes of intimate partner violence (IPV), but little qualitative research exists around how surviving this experience impacts the lives of women. Primary and secondary data ( N = 19) were used with a constructivist grounded theory approach to explore the lives of women aged 18 to 44 years, who were living with a TBI from IPV. Women described multiple aspects of living in fear that shaped their daily lives and ability to seek help and access resources. The central process of prioritizing safety emerged, with salient dimensions of maintaining a present orientation, exhibiting hyperprotection of children, invoking isolation as protection, and calculating risk of death. These findings add to the growing body of knowledge that women living with IPV are at high risk for receiving a TBI and are therefore a subgroup in need of more prevention and treatment resources.

Nursing Care of Women Veterans of the Iraq and Afghanistan Wars

The Iraq and Afghanistan wars are unlike earlier wars, and the women veterans who have served in them are unlike veterans of earlier wars. Now these veterans are presenting with distinctive general, genitourinary, reproductive, and behavioral health issues. When seeking health care after deployment, they may be accessing multiple health care providers across numerous sites, including the Veterans Health Administration and civilian facilities. Enhanced levels of understanding, respect, and concern for the many combat-related health challenges experienced by these veterans will help civilian nurses and other clinicians provide optimum care. Provision of health care to women veterans should be multidisciplinary and effectively coordinated among various health care providers and facilities to ensure that their post-deployment health and wellness needs are met.

Elucidating opportunities and pitfalls in the treatment of experimental traumatic brain injury to optimize and facilitate clinical translation

The aim of this review is to discuss the research presented in a symposium entitled "Current progress in characterizing therapeutic strategies and challenges in experimental CNS injury" which was presented at the 2016 International Behavioral Neuroscience Society annual meeting. Herein we discuss diffuse and focal traumatic brain injury (TBI) and ensuing chronic behavioral deficits as well as potential rehabilitative approaches. We also discuss the effects of stress on executive function after TBI as well as the response of the endocrine system and regulatory feedback mechanisms. The role of the endocannabinoids after CNS injury is also discussed. Finally, we conclude with a discussion of antipsychotic and antiepileptic drugs, which are provided to control TBI-induced agitation and seizures, respectively. The review consists predominantly of published data.

An Evidence Map of the Women Veterans' Health Research Literature (2008-2015)

BACKGROUND

Women comprise a growing proportion of Veterans seeking care at Veterans Affairs (VA) healthcare facilities. VA initiatives have accelerated changes in services for female Veterans, yet the corresponding literature has not been systematically reviewed since 2008. In 2015, VA Women's Health Services and the VA Women's Health Research Network requested an updated literature review to facilitate policy and research planning.

METHODS

The Minneapolis VA Evidence-based Synthesis Program performed a systematic search of research related to female Veterans' health published from 2008 through 2015. We extracted study characteristics including healthcare topic, design, sample size and proportion female, research setting, and funding source. We created an evidence map by organizing and presenting results within and across healthcare topics, and describing patterns, strengths, and gaps.

RESULTS

We identified 2276 abstracts and assessed each for relevance. We excluded 1092 abstracts and reviewed 1184 full-text articles; 750 were excluded. Of 440 included articles, 208 (47%) were related to mental health, particularly post-traumatic stress disorder (71 articles), military sexual trauma (37 articles), and substance abuse (20 articles). The number of articles addressing VA priority topic areas increased over time, including reproductive health, healthcare organization and delivery, access and utilization, and post-deployment health. Three or fewer articles addressed each of the common chronic diseases: diabetes, hypertension, depression, or anxiety. Nearly 400 articles (90%) used an observational design. Eight articles (2%) described randomized trials.

CONCLUSIONS

Our evidence map summarizes patterns, progress, and growth in the female Veterans' health and healthcare literature. Observational studies in mental health make up the majority of research. A focus on primary care delivery over clinical topics in primary care and a lack of sex-specific results for studies that include men and women have contributed to research gaps in addressing common chronic diseases. Interventional research using randomized trials is needed.

Assault-related mild traumatic brain injury, expectations of injury outcome, and the effect of different perpetrators: A vignette study

Few studies have examined the effect of varying the assault perpetrator on expectations of outcome from mild TBI. Using a cross sectional between groups design, individuals with no history of mild TBI were randomly allocated to one of two vignette conditions. The vignette depicted a mild TBI with fixed injury parameters and a different assault perpetrator (partner, n = 27; or stranger, n = 27). The participants were instructed to imagine that they had been injured as per the depiction, and then to anticipate the injury consequences 6-months later. An online questionnaire was used including: the Neurobehavioral Symptom Inventory, the Posttraumatic Stress Disorder Checklist-Civilian Version, the Impact of Events Scale-Revised, and the Perceived Ability to Cope with Trauma. The depicted injury was rated for the extent to which it was perceived as life-threatening, the subsequent diagnosis, and the global recovery prospects. The anticipated consequences of the injury (symptoms and trauma variables) did not differ across the conditions, all p's > 0.05. The expected outcomes for an assault-related mild TBI were not affected by perpetrator type. However, the study had several limitations and further consideration of this factor may still be warranted.

Intimate Partner Violence Victimization and Associated Implications for Health and Functioning Among Male and Female Post-9/11 Veterans

BACKGROUND

There is increased emphasis on identifying patients who experience intimate partner violence (IPV) in Department of Veterans Affairs and other health care settings. A better understanding of IPV's implications for health and functioning is needed among post-911 Veterans, and especially male Veterans, to inform IPV screening and response.

OBJECTIVES

To identify past 6-month IPV experienced among partnered post-9/11 Veterans and examine sex-based associations between IPV and health.

RESEARCH DESIGN

A national sample of Veterans completed a survey that included measures of IPV victimization and health. Types of IPV and relationships with health and functioning were examined separately for male and female Veterans.

SUBJECTS

In total, 407 post-9/11 Veterans (52% women) in intimate relationships.

MEASURES

IPV victimization was assessed with the Conflict Tactics Scales-Revised. Health and functioning indicators included posttraumatic stress disorder (PCL-5) and depression (Beck Depression Inventory-Primary Care) symptoms, physical health-related quality of life (Short-Form 12-item Health Survey), and occupational functioning (Inventory of Psychosocial Functioning).

RESULTS

Nearly two thirds of both men and women reported past 6-month IPV, with greatest endorsement of psychological aggression (65% of men, 59% of women). A total of 8% of men and 7% of women reported physical IPV and 4% of men and 7% of women reported sexual IPV. Psychological aggression was strongly linked with mental health for both sexes and greater occupational impairment for men. Physical and sexual IPV were associated with more severe mental health symptoms for women while physical IPV was negatively associated with physical health-related quality of life for men.

CONCLUSIONS

Recent IPV victimization, especially psychological aggression, is a key health issue for partnered male and female post-9/11 Veterans. Practice and research implications are discussed.

Traumatic brain injury and PTSD symptoms as a consequence of intimate partner violence

OBJECTIVE

To effectively diagnose and treat women who have experienced intimate partner violence (IPV), it is important to identify the full range of physical and mental health consequences, including hidden wounds such as traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD). We aimed to identify the occurrence of IPV-related TBI and associated PTSD symptoms among women veterans who experienced IPV.

METHODS

A web-based survey was administered in 2014 to a national sample of U.S. women veterans. Among 411 respondents (75% participation rate), 55% reported IPV during their lives. These participants (N=224) completed screening measures of IPV-related TBI, PTSD, and past-year IPV and comprised the current sample.

RESULTS

A total of 28.1% (n=63) met criteria for IPV-related TBI history, and 12.5% (n=28) met criteria for IPV-related TBI with current symptoms. When adjusting for race, income, and past-year IPV, women with IPV-related TBI with current symptoms were 5.9 times more likely to have probable IPV-related PTSD than those with no IPV-related TBI history. Despite symptom overlap between TBI and PTSD, women with IPV-related TBI with current symptoms were significantly more likely to meet criteria for all four DSM-5 PTSD symptom clusters compared to women with an IPV-related TBI history without current symptoms (Cramér's V's=.34-.42).

CONCLUSION

Findings suggest there may be clinical utility in screening women who experience lifetime IPV for both TBI and PTSD symptoms in order to help clinicians better target their examinations, treatment, and referrals.

Acknowledging the Risk for Traumatic Brain Injury in Women Veterans

Since the Iraq and Afghanistan wars began, an unprecedented number of women have been engaging in combat operations. Likewise, the number of women using Department of Veterans Affairs (VA) services has doubled since 2001. Military service, and deployment to combat in particular, poses certain risks for traumatic brain injury (TBI)-for all service members. However, women may have additional military and nondeployment risk factors such as intimate partner violence (IPV). We briefly review the definition and classification issues related to TBI, as well as common acute and chronic health symptoms after TBI. Specific sex differences in prognosis after TBI, in particular the neurobehavioral symptoms, are also reviewed. We then focus on the emerging literature regarding TBI in women veterans including the etiologies, outcomes, and unique challenges this population faces. The article concludes with suggestions for enhanced screening by VA and non-VA providers alike, as well as directions for future research and clinical inquiry.

Systematic review of mental health disorders and intimate partner violence victimisation among military populations

PURPOSE

There is growing awareness of the problem of intimate partner violence (IPV) among military populations. IPV victimisation has been shown to be associated with mental disorder. A better understanding of the link between IPV and mental disorder is needed to inform service development to meet the needs of military families. We aimed to systematically review the literature on the association between IPV victimisation and mental health disorders among military personnel.

METHODS

Searches of four electronic databases (Embase, Medline, PsycINFO, and Web of Science) were supplemented by reference list screening. Heterogeneity among studies precluded a meta-analysis.

RESULTS

Thirteen studies were included. There was stronger evidence for an association between IPV and depression/alcohol problems than between IPV and PTSD. An association between IPV and mental health problems was more frequently found among veterans compared to active duty personnel. However, the link between IPV and alcohol misuse was more consistently found among active duty samples. Finally, among active duty personnel psychological IPV was more consistently associated with depression/alcohol problems than physical/sexual IPV. The review highlighted the lack of research on male IPV victimisation in the military.

CONCLUSIONS

There is evidence that the burden of mental health need may be significant among military personnel who are victims of IPV. The influence of attitudes towards gender in the military on research in this area is discussed. Further research is needed to inform development of services and policy to reduce IPV victimisation and the mental health consequences among military personnel.

New vignettes for the experimental manipulation of injury cause in prospective mild traumatic brain injury research

PURPOSE

This study developed standardized vignettes that depict a mild traumatic brain injury (TBI) from one of several causes and subjected them to formal expert review.

METHOD

A base vignette was developed using the World Health Organization operational criteria for mild TBI. Eight specific causes (e.g. sport vs assault) were examined. A convenience sample of mild TBI experts with a discipline background of Neuropsychology from North America, Australasia and Europe (n = 21) used an online survey to evaluate the vignettes and rated the role of cause on outcome.

RESULTS

The vignette suite was rated as fitting the mild TBI WHO operational diagnostic criteria at least moderately well. When compared to other factors, cause was not rated as significantly contributing to outcome. When evaluated in isolation, approximately half of the sample rated cause as important or very important and at least two of three clinical outcomes were associated with a different cause.

DISCUSSION

The vignettes may be useful in experimental mild TBI research. They enable the injury parameters to be controlled so that the effects of cause can be isolated and examined empirically. Such studies should advance understanding of the role of this factor in mild TBI outcome.

Female veterans' preferences for counseling related to intimate partner violence: Informing patient-centered interventions

OBJECTIVE

Female veterans are at high risk for intimate partner violence (IPV). A critical issue in the provision of health care to women who experience IPV is the delivery of effective brief counseling interventions that address women's unique needs. We aimed to identify female veterans' priorities and preferences for healthcare-based IPV counseling.

METHOD

A 2014 Web-based survey was administered to a national sample of US female veterans. Among 411 respondents (75% participation rate), 55% (n=226) reported IPV during their lifetime. These women identified priorities for the content focus of IPV-related counseling and preferences for the delivery of these services.

RESULTS

Women prioritized counseling that focuses on physical safety and emotional health, with learning about community resources being a relatively lower priority. Participants preferred counseling to focus specifically on enhancing coping skills and managing mental health symptoms. In addition, women want counseling to be individualized and preferred the option to meet with a counselor immediately following disclosure. Affordable services and attention to privacy concerns were of paramount importance in the context of IPV-related counseling.

CONCLUSION

These findings can inform patient-centered brief counseling interventions for women who experience IPV, which may ultimately reduce health disparities and violence among this population.
