Characterization of Cognitive-Motor Function in Women Who Have Experienced Intimate Partner Violence-Related Brain Injury

Characterizing Intimate Partner Violence-Caused Brain Injury in a Sample of Survivors in the Two Spirit, Lesbian, Gay, Bisexual, Transgender, Queer or Questioning Community

Research in the field of intimate partner violence-caused brain injury (IPV-BI) has predominantly focused on heterosexual women, ignoring the unique needs of the Two Spirit, Lesbian, Gay, Bisexual, Transgender, Queer or Questioning (2S/LGBTQ) community. The purpose of this exploratory research was to better understand the prevalence of IPV and IPV-BI in 2S/LGBTQ relationships where IPV was defined as physical, psychological, financial, sexual, and/or identity-based abuse from a current of former intimate partner. This study used a cross sectional internet-based survey that ran from September to December of 2022. In addition to descriptive statistics, prevalence rates and their corresponding Wilson Score confidence intervals are reported to estimate the proportion of individuals who experienced IPV and IPV-BI. Finally, for both gender identity and sexual orientation, we tested whether participants with each identity had differing levels of brain injury severity compared to participants who did not hold that identity using Mann-Whitney U tests. In total, 170 2S/LGBTQ+ adults responded to the survey. Among the respondents, 54% identified as Two-Spirit, 24% identified as gay, 17% identified as queer, 14% identified as bisexual, and 8% identified as lesbian or pansexual, respectively. Respondents were predominantly multiracial, post-secondary educated, full-time employed, cisgender women (35%) or cisgender men (19%). The overwhelming majority reported lifetime prevalence of IPV at 98% (n = 166, 95% CI [94.11, 99.08]). Additionally, 68% (n = 115, 95% CI [60.29, 74.22]) of participants reported symptoms consistent with an IPV-BI. These results are consistent with the findings that the 2S/LGBTQ community are at heightened risk of experiencing physical IPV. These findings are the first to our knowledge to report a high rate of symptoms consistent with an IPV-BI in the 2S/LGBTQ population.

Eye Movement Desensitization and Reprocessing: Efficacy in Improving Clinical, Neuropsychological, and Quality of Life in Women Victims of Violence

Background

The number of female victims of violence has significantly increased in recent years, resulting in physical, mental, and social damage.

Objective

To determine the effectiveness of the eye movement desensitization and reprocessing (EMDR) psychotherapeutic model compared with narrative exposure therapy (NET) as treatments for clinical improvement, neuropsychological outcomes, and quality of life in women who have experienced violence.

Methods

A randomized experimental study was conducted, involving 120 women exposed to physical, psychological, and sexual violence, who were assigned to either an EMDR or NET group. An extensive battery of clinical, neuropsychological, and quality of life tests was administered both before and after a 10-session therapeutic intervention.

Results

Compared with the group of women treated with NET, the group of women who received EMDR therapy, exposed to physical, psychological, and sexual violence, achieved a greater decrease in anxiety (p = 0.001), depression (p = 0.001), and post-traumatic symptoms (p = 0.002). Additionally, there was an increase in the quality of life index (p = 0.001), performance in working memory (p = 0.000), and executive functioning tests (p = 0.000), compared with NET.

Conclusions

EMDR proved to be more effective compared with NET in reducing post-traumatic clinical symptoms, increasing the level of quality of life, and enhancing cognitive performance in women affected by gender-based violence. Additionally, it demonstrated independence in therapeutic response across most estimated sociodemographic factors, making it a therapy with broader therapeutic reach in the community of Ecuadorian women.

Detecting a hidden pandemic: The current state and future direction of screening and assessment tools for intimate partner violence-related brain injury

Intimate partner violence (IPV) is a major global concern, and IPV victim-survivors are at an increased risk of brain injury (BI) due to the physical assaults. IPV-BI can encompass both mild traumatic brain injury (mTBI) and non-fatal strangulation (NFS), but IPV-BI often goes undetected and untreated due to a number of complicating factors. Therefore, the clinical care and support of IPV victim-survivors could be enhanced by BI screening and assessment in various settings (e.g., first responders, emergency departments, primary care providers, rehabilitation, shelters, and research). Further, appropriate screening and assessment for IPV-BI will support more accurate identifications, and prevalence estimates, improve understanding of health implications, and have the potential to inform policy decisions. Here we overview the seven available tools that have been used for IPV-BI screening and assessment purposes, including the BISA, BISQ-IPV, BAT-L/IPV, OSU TBI-ID, the HELPS, and the CHATS, and outline the advantages and disadvantages of these screening tools in the clinical, community, and research settings. Recommendations for further research to enhance the validity and utility of these tools are also included.

Pediatric Brain Injuries are Associated With Intimate Partner Violence-Related Brain Injuries Among Women in Adulthood

OBJECTIVE

Prior studies have reported associations between childhood physical abuse and intimate partner violence (IPV). However, there has been limited literature examining the relationship between pediatric brain injuries and IPV-related brain injuries later in life. We examined the association between childhood brain injuries and brain injuries sustained from IPV in adulthood.

SETTING

Participants were recruited through Mass General Brigham's "Rally," social media, and information sheets distributed in locations likely to serve women in current or past abusive relationships (eg, domestic violence shelters, and IPV support programs).

PARTICIPANTS

Women who have experienced IPV with and without brain injury (n = 129), ages 19 to 69.

DESIGN

Retrospective, cross-sectional study design.

MAIN MEASURES

We administered the Ohio State University Traumatic Brain Injury Identification Method and the Brain Injury Severity Assessment to assess brain injury history, and the Childhood Trauma Questionnaire (CTQ). A logistic regression was used to examine the association between pediatric brain injuries and IPV-related brain injuries, adjusting for childhood trauma, years of education, and age.

RESULTS

A majority of participants (64.3%) reported experiencing at least 1 IPV-related brain injury, and 30.2% experienced at least 1 childhood brain injury. Child abuse-related brain injuries occurred in 10.9% of the sample, whereas childhood brain injuries from other causes occurred in 19.4% of participants. Participants who sustained at least 1 childhood BI were significantly more likely to sustain a future IPV-related brain injury as an adult (OR = 4.652, P = .004). For each additional childhood BI sustained, participants were more likely to sustain an IPV-related BI (OR = 3.198, P = .005).

CONCLUSION

This study illustrates a high prevalence of childhood brain injuries among women who have experienced IPV and identifies an association between pediatric brain injuries and brain injuries due to partner violence in adulthood. Our findings speak to the urgency of increasing our understanding of childhood brain injuries and whether they or other related factors might confer an increased risk for brain injuries or possibly IPV later in life.

"Using the right tools and addressing the right issue": A qualitative exploration to support better care for intimate partner violence, brain injury, and mental health

BACKGROUND

Intimate partner violence (IPV) is a global public health crisis. Often repetitive and occurring over prolonged periods of time, IPV puts survivors at high risk of brain injury (BI). Mental health concerns are highly prevalent both among individuals who have experienced IPV and those who have experienced BI, yet the interrelatedness and complexity of these three challenges when experienced together is poorly understood. This qualitative study explored care provision for IPV survivors with BI (IPV-BI) and mental health concerns from the perspectives of both survivors and providers.

METHODS

This qualitative interpretive description study was part of a broader research project exploring employment, mental health, and COVID-19 implications for survivors of IPV-BI. Participants (N = 24), including survivors and service providers, participated in semi-structured group and individual interviews between October 2020 and February 2021. Interviews were recorded, transcribed, and thematically analyzed.

FINDINGS

Four themes were developed from interview findings: 1) identifying BI and mental health as contributing components to survivors' experiences is critical to getting appropriate care; 2) supporting survivors involves a "toolbox full of strategies" and a flexible approach; 3) connecting and collaborating across sectors is key; and 4) underfunding and systemic barriers hinder access to care. Finally, we share recommendations from participants to better support IPV survivors.

CONCLUSIONS

Identifying both BI and mental health concerns among IPV survivors is critical to providing appropriate supports. Survivors of IPV experiencing BI and mental health concerns benefit from a flexible and collaborative approach to care; health and social care systems should be set up to support these collaborative approaches.

Intimate Partner Violence-Related Brain Injury: Unmasking and Addressing the Gaps

Intimate partner violence (IPV) is a significant, global public health concern. Women, individuals with historically underrepresented identities, and disabilities are at high risk for IPV and tend to experience severe injuries. There has been growing concern about the risk of exposure to IPV-related head trauma, resulting in IPV-related brain injury (IPV-BI), and its health consequences. Past work suggests that a significant proportion of women exposed to IPV experience IPV-BI, likely representing a distinct phenotype compared with BI of other etiologies. An IPV-BI often co-occurs with psychological trauma and mental health complaints, leading to unique issues related to identifying, prognosticating, and managing IPV-BI outcomes. The goal of this review is to identify important gaps in research and clinical practice in IPV-BI and suggest potential solutions to address them. We summarize IPV research in five key priority areas: (1) unique considerations for IPV-BI study design; (2) understanding non-fatal strangulation as a form of BI; (3) identifying objective biomarkers of IPV-BI; (4) consideration of the chronicity, cumulative and late effects of IPV-BI; and (5) BI as a risk factor for IPV engagement. Our review concludes with a call to action to help investigators develop ecologically valid research studies addressing the identified clinical-research knowledge gaps and strategies to improve care in individuals exposed to IPV-BI. By reducing the current gaps and answering these calls to action, we will approach IPV-BI in a trauma-informed manner, ultimately improving outcomes and quality of life for those impacted by IPV-BI.

Tentative Causes of Brain and Neuropsychological Alterations in Women Victims of Intimate Partner Violence

Victims of Intimate Partner Violence Against Women (IPVAW) experience neuropsychological and cerebral changes, which have been linked to several tentative causal mechanisms, including elevated cortisol levels, psychopathological disorders, traumatic brain injury (TBI), hypoxic/ischemic brain damage, and medical conditions related to IPVAW. While these mechanisms and their effects on brain function and neuropsychological health are well-documented in other clinical populations, they manifest with unique characteristics in women affected by IPVAW. Specifically, IPVAW is chronic and repeated in nature, and mechanisms are often cumulative and may interact with other comorbid conditions. Thus, in light of existing literature on neuropsychological alterations in other populations, and recognizing the distinct features in women who experience IPVAW, we propose a new theoretical model-the Neuro-IPVAW model. This framework aims to explain the complex interplay between these mechanisms and their impact on cognitive and brain health in IPVAW victims. We anticipate that this theoretical model will be valuable for enhancing our understanding of neuropsychological and brain changes related to intimate partner violence, identifying research gaps in these mechanisms, and guiding future research directions in this area.

The effect of traumatic brain injury on learning and memory: A synaptic focus

Deficits in learning and memory are some of the most commonly reported symptoms following a traumatic brain injury (TBI). We will examine whether the neural basis of these deficits stems from alterations to bidirectional synaptic plasticity within the hippocampus. Although the CA1 subregion of the hippocampus has been a focus of TBI research, the dentate gyrus should also be given attention as it exhibits a unique ability for adult neurogenesis, a process highly susceptible to TBI-induced damage. This review examines our current understanding of how TBI results in deficits in synaptic plasticity, as well as how TBI-induced changes in endocannabinoid (eCB) systems may drive these changes. Through the synthesis and amalgamation of existing data, we propose a possible mechanism for eCB-mediated recovery in synaptic plasticity deficits. This hypothesis is based on the plausible roles of CB1 receptors in regulating inhibitory tone, influencing astrocytes and microglia, and modulating glutamate release. Dysregulation of the eCBs may be responsible for deficits in synaptic plasticity and learning following TBI. Taken together, the existing evidence indicates eCBs may contribute to TBI manifestation, pathogenesis, and recovery, but it also suggests there may be a therapeutic role for the eCB system in TBI.

Listening to the Voices of Aboriginal and Torres Strait Islander Women in Regional and Remote Australia About Traumatic Brain Injury From Family Violence: A Qualitative Study

INTRODUCTION

Indigenous women experience high rates of family violence-related head injuries. At present, lived experience accounts from Indigenous women are absent, which results in incomplete understandings and inadequate responses that have detrimental impacts on them and their families. The aim of this study was to gain insight into Indigenous women's personal and family perspectives regarding violence-related traumatic brain injury (TBI), including impacts on life, as well as decision-making processes about healthcare access and engagement.

METHODS

Purposeful sampling was used to complete semi-structured interviews with 18 Indigenous women living in regional and remote Australia who had experienced TBI from family violence. The data from these interviews were augmented by data from interviews and focus groups with 28 community members, including family members or carers of Indigenous women living with TBI from family violence.

RESULTS

Three themes were conceptualised based on the data and research aims: interweaving of the past and the present-ways women experience brain injury; factors that inform decision-making to access healthcare; and managing everyday changes that result from TBI from family violence. Indigenous women described living with a range of symptoms following repeated head injuries including problems with memory, cognition and concentration. A range of strategies to manage long-term symptoms of TBI were used by Indigenous women and when they did seek healthcare, Indigenous women were required to navigate a range of barriers.

CONCLUSIONS

The findings identify a range of gaps in healthcare and housing supports for Indigenous women with TBI from violence, highlighting the significant investment needed to develop responsive and appropriate pathways of care in regional and remote areas. A range of suggestions are discussed including development of a specialised workforce who can provide apppropriate follow-up support, co-designed concussion clinics and educational resources. TBI must also be a key aspect of policy and practice for services working with Indigenous women who have experienced violence to ensure appropriate responses are provided.

PUBLIC OR PATIENT CONTRIBUTION

Indigenous women shared their views and experiences of TBI from family violence as well as decision-making about accessing healthcare and managing TBI symptoms. As such, study participants provided public contributions to the research.

Characterizing Possible Acute Brain Injury in Women Experiencing Intimate Partner Violence: A Retrospective Chart Review

Survivors of intimate partner violence (IPV) often experience violent blows to the head, face, and neck and/or strangulation that result in brain injury (BI). Researchers reviewed the de-identified forensic nursing examination records of 205 women. More than 88% of women were subjected to multiple mechanisms of injury with in excess of 60% experiencing strangulation. About 31% disclosed various symptoms consistent with BI. Women experiencing strangulation were 2.24 times more likely to report BI-related symptoms compared to those who reported no strangulation. In conclusion, women experiencing IPV are prone to BI suggesting early screening and appropriate management are warranted.

A Four-Country Study of Strangulation-Related Alterations in Consciousness in Women Who Have Experienced Intimate Partner Violence: Co-Occurrence with Traumatic Brain Injuries and Measures of Psychological Distress

At least one in three women experience intimate partner violence (IPV) in their lifetime. The most commonly sustained IPV-related brain injuries include strangulation-related alterations in consciousness (S-AICs) and traumatic brain injuries (TBIs). Moreover, survivors of IPV-related S-AICs and/or TBIs often demonstrate psychological distress such as depression, anxiety, and post-traumatic stress. However, the co-occurrence of S-AICs and TBIs, and whether such TBIs may be moderate to severe, has not been systematically examined, and most data have been collected from women in North America. The purpose of this study was to examine the co-occurrence of IPV-related S-AICs and TBIs across a range of geographical locations and to determine the extent to which these S-AICs are related to psychological distress. Women who had experienced physical IPV (n = 213) were included in this secondary analysis of retrospectively collected data across four countries (Canada, the United States, Spain, and Colombia). The Brain Injury Severity Assessment (BISA) was used to assess IPV-related BI across all sites. Because various questionnaires were employed to assess levels of depression, anxiety, and post-traumatic stress disorder at each site, we created a standardized composite score by converting raw scores into Z-scores for analysis. Mann-Whitney U tests and chi-square tests were conducted to examine differences between women with and without experience of S-AICs and to discover if there was a relationship between the occurrence of S-AICs and TBIs. Analysis of variance and analysis of covariance (to control for the potential confounding effects of age, education, and non IPV-related TBI) were used to compare levels of psychological distress in women who had or had not experienced S-AICs. Approximately, 67% of women sustained at least one IPV-related BI (i.e., TBI and/or S-AIC). In a subsample of women who sustained at least one IPV-related BI, approximately 37% sustained both S-AICs and TBIs, 2% sustained only S-AICs (with no TBIs), and 61% sustained TBIs exclusively (with no S-AICs). Furthermore, women who had sustained S-AICs (with or without a TBI) were more likely to have experienced a moderate-to-severe BI than those who had not sustained an S-AIC (BISA severity subscale: U = 3939, p = 0.006). In addition, women who experienced S-AICs (with or without a TBI) reported higher levels of psychological distress compared with women who never experienced S-AICs, irrespective of whether they occurred once or multiple times. These data underscore the importance of assessing for S-AIC in women who have experienced IPV and when present, to also assess for TBIs and the presence of psychological distress. Unfortunately, there were methodological differences across sites precluding cross-site comparisons. Nonetheless, data were collected across four culturally and geographically diverse countries and, therefore, highlight IPV-related BIs as a global issue that needs to be aggressively studied with policies established and then implemented to address findings.

Investigating the Efficacy of a Community Support Network Rehabilitation Intervention for Improving Resiliency, Quality of Life, and Neurocognitive Function in Survivors of Intimate Partner Violence-Caused Brain Injury: Protocol for a Feasibility Study

BACKGROUND

Globally, approximately 1 in 3 women experience intimate partner violence (IPV) in their lifetime. Brain injury (BI) is a common, yet often unrecognized, consequence of IPV. BIs caused by IPV tend to be mild, occur repetitively over the course of months or years, are remote in time, and result in chronic symptoms. Similar to BI from other causes, therapeutic treatment for women with IPV-caused BI (IPV-BI) is crucial to help resolve any physical or cognitive impairments, enhance the quality of life (QoL), and minimize longer-term neurodegeneration.

OBJECTIVE

This study aims to investigate the feasibility and efficacy of a community support network (CSN) rehabilitation intervention regarding its impact on resiliency, QoL, and neurocognitive function.

METHODS

In this pre- and postexperimental design, women (aged 18 to 50 years) who are survivors of IPV and IPV-BI will be recruited from various community organizations serving survivors of IPV. Exclusion criteria will include current pregnancy and any diagnosed neurological disorder known to affect cerebrovascular, neurocognitive, or sensorimotor function. A CSN rehabilitation intervention that includes aerobic exercise, cognitive training, mindfulness meditation, and counseling will be administered. A trauma-informed approach will be integrated into the design and implementation of the program. Furthermore, the program will include a participant navigator who will provide trauma- and violence-informed advocacy and systems navigation support to participants, in addition to facilitating a monthly peer support group. The intervention will be provided for 2.5 hours a day and 2 days a week for 3 months. Participants will complete psychological assessments and provide clinic-demographic information in the first assessment. In the second (before intervention), third (after intervention), and fourth (at follow-up) sessions, they will complete tests of resiliency, QoL, and neurocognition. The estimated sample size is 100. The objective of this study will be accomplished by quantitatively measuring resiliency, QoL, and neurocognition before and immediately after the intervention. A follow-up assessment will occur 3 months after the completion of the intervention to evaluate the maintenance of any improvements in function. One-way ANOVAs will be used to evaluate the intervention outcome across the testing times. Relationships among various variables will be explored using regression analysis.

RESULTS

We anticipate that the CSN rehabilitation intervention will be effective in improving resiliency, QoL, and neurocognitive function in women who have experienced IPV-BI. Furthermore, we anticipate that this intervention will be feasible in terms of study recruitment, adherence, and retention.

CONCLUSIONS

The CSN rehabilitation intervention will have a positive impact on resiliency, QoL, and neurocognitive functions in survivors of IPV-BI. Subsequently, a comparative study will be conducted by recruiting a control group receiving usual care.

Neurovascular coupling is altered in women who have a history of brain injury from intimate partner violence: a preliminary study

Introduction

Intimate partner violence (IPV) is a global health crisis with 30% of women over the age of 15 experiencing at least one event in their lifetime. Brain injury (BI) due to head impacts and/or strangulation is a common but understudied part of this experience. Previous research has shown BI from other injury mechanisms can disrupt neurovascular coupling (NVC). To gain further insight into whether similar changes occur in this population, we assessed NVC responses in women with a history of IPV-BI.

Methods

NVC responses were measured for the middle and posterior cerebral arteries (MCA, PCA) using transcranial Doppler ultrasound while participants performed a complex visual search task. The lifetime history of previous exposure to IPV-BI was captured using the Brain Injury Severity Assessment (BISA) along with measures of post-traumatic stress disorder (PTSD), anxiety, depression, substance use, and demographic information. Initial analyses of NVC metrics were completed comparing participants who scored low vs. high on the BISA or did or did not experience non-fatal strangulation followed by a stepwise multiple regression to examine the impact of PTSD, anxiety, and depression on the relationship between the NVC metrics and IPV-BI.

Results

Baseline and peak cerebral blood velocity were higher and the percentage increase was lower in the PCA in the low compared to the high BISA group whereas no differences between the groups were apparent in the MCA. In addition, those participants who had been strangled had a lower initial slope and area under the curve in the PCA than those who had not experienced strangulation. Finally, the stepwise multiple regression demonstrated the percentage increase in the PCA was significantly related to the BISA score and both depression and anxiety significantly contributed to different components of the NVC response.

Conclusions

This preliminary study demonstrated that a lifetime history of IPV-BI leads to subtle but significant disruptions to NVC responses which are modulated by comorbid depression and anxiety. Future studies should examine cerebrovascular function at the acute and subacute stages after IPV episodes to shed additional light on this experience and its outcomes.

Repeated mild traumatic brain injury causes sex-specific increases in cell proliferation and inflammation in juvenile rats

Childhood represents a period of significant growth and maturation for the brain, and is also associated with a heightened risk for mild traumatic brain injuries (mTBI). There is also concern that repeated-mTBI (r-mTBI) may have a long-term impact on developmental trajectories. Using an awake closed head injury (ACHI) model, that uses rapid head acceleration to induce a mTBI, we investigated the acute effects of repeated-mTBI (r-mTBI) on neurological function and cellular proliferation in juvenile male and female Long-Evans rats. We found that r-mTBI did not lead to cumulative neurological deficits with the model. R-mTBI animals exhibited an increase in BrdU + (bromodeoxyuridine positive) cells in the dentate gyrus (DG), and that this increase was more robust in male animals. This increase was not sustained, and cell proliferation returning to normal by PID3. A greater increase in BrdU + cells was observed in the dorsal DG in both male and female r-mTBI animals at PID1. Using Ki-67 expression as an endogenous marker of cellular proliferation, a robust proliferative response following r-mTBI was observed in male animals at PID1 that persisted until PID3, and was not constrained to the DG alone. Triple labeling experiments (Iba1+, GFAP+, Brdu+) revealed that a high proportion of these proliferating cells were microglia/macrophages, indicating there was a heightened inflammatory response. Overall, these findings suggest that rapid head acceleration with the ACHI model produces an mTBI, but that the acute neurological deficits do not increase in severity with repeated administration. R-mTBI transiently increases cellular proliferation in the hippocampus, particularly in male animals, and the pattern of cell proliferation suggests that this represents a neuroinflammatory response that is focused around the mid-brain rather than peripheral cortical regions. These results add to growing literature indicating sex differences in proliferative and inflammatory responses between females and males. Targeting proliferation as a therapeutic avenue may help reduce the short term impact of r-mTBI, but there may be sex-specific considerations.

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.

Intimate Partner Violence-Related Brain Injury Among Colombian Women

OBJECTIVE

The aim of this study was to assess the prevalence of brain injury (BI) and its relationship to cognitive and psychological outcomes in women survivors of intimate partner violence (IPV) in Colombia, South America.

SETTING

Women's shelters and organizations in Barranquilla, Colombia.

PARTICIPANTS

Seventy women from the city of Barranquilla, Colombia, who experienced any form of IPV.

DESIGN

Cross-sectional, retrospective.

MAIN MEASURES

Participants were administered the computerized EMBRACED neuropsychological battery to assess learning, working and long-term memory, cognitive flexibility, and processing speed. Participants also completed measures of psychological symptoms. Partner violence severity was assessed with a semistructured interview for survivors of domestic violence. Presence and severity of IPV-related BI were assessed using the Brain Injury Severity Assessment (BISA).

RESULTS

Thirty-one percent of women sustained at least one BI during an abusive relationship, and 10% sustained repetitive BIs. Furthermore, BI was negatively associated with measures of long-term and working memory, cognitive flexibility, as well as a trending ( P = .05) positive association with depression. With the exception of the relationship between BI and cognitive flexibility, which was substantially reduced and no longer significant, all of these relationships were nearly identical in strength when controlling for abuse severity, socioeconomic status, and educational level.

CONCLUSION

These data are the first to specifically examine IPV-related BI in relation to cognitive and psychological functioning in a sample of Colombian women. These data add cross-cultural knowledge to the limited work in this area that has largely focused on women in North America.

The Concussion Awareness Training Tool for Women's Support Workers Improves Knowledge of Intimate Partner Violence-Caused Brain Injury

Women who experience physical intimate partner violence (IPV) are at high risk of suffering a brain injury (BI) due to head impacts and/or strangulation. Currently, most staff at women's shelters tend not to be aware of IPV-caused BIs. The objective of this study was to address this by developing a new online module within the Concussion Awareness Training Tool (cattonline.com) specifically focused on IPV-caused BI, and measuring its effectiveness in increasing BI awareness and knowledge among staff members at women's shelters. A mixed-methods approach was used which included (i) a survey to measure participant knowledge before and after completing the module; (ii) a 1-on-1 interview 6 months post-training to better understand participants' perceptions of what effect the training had on how they worked with women in their job; and (iii) an evaluation of the content of the module using behavior change techniques. About 81 participants recruited from staff at women's shelters completed the pre/post survey. The average BI knowledge score increased significantly from the pre-survey (M = 8.12/12, SD = 1.05) to the post-survey (M = 9.72/12, SD = 1.62), t(80) = 9.12, P < .001, d = 1.01). Analysis of the interviews with 9 participants highlighted 3 main themes arising from the module: knowledge, mindfulness, and advocacy. All participants felt their knowledge of IPV-caused BIs had increased and said they would recommend the training to their co-workers. Analysis of the module content revealed the most frequent behavior change techniques were related to instructions on how to perform screening and accommodation for IPV-caused BI. The results showed the module was effective in increasing knowledge of IPV-caused BIs amongst women's shelter staff as well as improving how they advocate for, and are mindful of, their clients with BIs. This online training may help improve the care women with IPV-caused BIs receive, and ultimately improve their quality of life.

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.

Sex and Gender Science: The World Writes on the Body

Sex and Gender Science seeks to better acknowledge that the body cannot be removed from the world it inhabits. We believe that to best answer any neuroscience question, the biological and the social need to be addressed through both objective means to learn, "how it is like" and subjective means to learn, "what it is like." We call bringing the biological and social together, "Situated Neuroscience" and the mixing of approaches to do so, Very Mixed Methods. Taken together, they constitute an approach to Sex and Gender Science. In this chapter, we describe neural phenomena for which considering sex and gender together produces a fuller knowledge base: sleep, pain, memory, and concussion. For these brain phenomena examples, studying only quantitative measures does not reveal the full impact of these lived experiences on the brain but studying only the qualitative would not reveal how the brain responds. We discuss how Sex and Gender Science allows us to begin to bring together biology and its social context and acknowledge where context can contribute to resolving ignorance to offer more expansive, complementary, and interrelating pictures of an intricate neuro-landscape.

How CARE Tools Are Being Used to Address Brain Injury and Mental Health Struggles With Survivors of Domestic Violence

INTRODUCTION

CARE (Connect, Acknowledge, Respond, and Evaluate) is an advocacy framework developed for domestic violence service organization (DVSO) providers to address and accommodate domestic violence (DV) survivors with brain injury and mental health struggles. The CARE tools were designed for use by advocates and include the Just Breathe booklet, the Head Injury education card, and the Invisible Injuries booklet.

OBJECTIVE

The purpose of this study was to report findings on how CARE tools are being used by DVSO providers as well as their impact on DVSO advocacy practice.

METHODS

Post-CARE retrospective process evaluation online surveys (n = 60) and focus groups (n = 10 groups; 57 advocates) were conducted with consenting staff at 5 DVSOs in Ohio who partnered with the state coalition to develop and evaluate CARE, overseen by a university research partner. Rigorous, iterative coding qualitative analysis methods, endorsed by the Centers for Disease Control and Prevention, were used (Cohen's κ = 0.903 [stage 1] and 0.810 [stage 2]).

RESULTS

The use of CARE tools has been integral to DVSO providers' implementation of the CARE advocacy framework. DVSO advocates are using CARE tools to Connect with self, survivors, and other systems; to Acknowledge that head trauma and mental health struggles are common among survivors and that ongoing education and self-care are necessary for advocates. Advocates have been able to provide a more holistic Response through accommodation within DVSOs and referral to other providers, often by using the CARE tools, including the Head Injury education card.

CONCLUSION

CARE tools were designed for lay use to address head trauma, strangulation, and mental health struggles with DV survivors and are free for download at the Center on Partner Inflicted Brain Injury website: https://www.odvn.org/brain-injury. More widespread use of these tools by advocates has the potential to improve services for DV survivors and address what have historically been invisible injuries and mental health struggles in the population.

Prevalence and Risk Factors for Intimate Partner Physical Violence-Related Acquired Brain Injury Among Visitors to Justice Center in New York

OBJECTIVE

The recent United States Government Accountability Office report highlights the need for improved data on the prevalence of intimate partner violence (IPV)-related acquired brain injury (ABI) to help direct Health & Human Services public efforts. This article identifies the prevalence and risk factors for IPV-related ABI among survivors of IPV at a Justice Center in New York.

SETTING

Community Justice Center.

PARTICIPANTS

Forty survivors of IPV, aged 17 to 73 years (median 32, interquartile range: 25.25, 42) were assessed within 60 days of sustaining physical violence.

DESIGN

Retrospective chart review.

MAIN MEASURES

The HELPS and the Danger Assessment-Revised were used at the initial Center visit.

RESULTS

Of the 40 physical IPV survivors screened, all (100%) reported a prior history of partner-induced ABI within the past 60 days. Thirty-seven (92.5%) survivors also reported sustaining at least 1 potential hypoxic brain injury from strangulation. However, only 16 (40%) survivors screened positive on the HELPS for a history of IPV-related mild traumatic brain injury. Females (95%) and individuals with low income (67.5%) largely comprised our sample. Compared with the County's average, the proportion of African Americans/Blacks and refugees was 227% higher (42.5% vs 13%) and 650% higher (7.5% vs 1.09%), respectively. Refugee status (P = .017) also correlated with number of previous ABIs. On an exploratory binary logistic regression with stepwise selection, only balance difficulties (P = .023) and difficulty concentrating/remembering (P = .009) predicted a positive screen for mild traumatic brain injury.

CONCLUSIONS

Consistent with previous findings, our data indicate a high prevalence of IPV-related ABI among visitors to a New York Justice Center. An overrepresentation of African Americans/Blacks and refugees in our sample relative to the region signified a higher prevalence of IPV in these populations and warrants a provision of more trauma-informed ABI resources to these groups/communities. Intimate partner violence survivors visiting Justice Centers should be screened for motor/neurocognitive symptoms suggestive of mild traumatic brain injury. Further research to identify the prevalence and risk factors of IPV-related ABI statewide and nationwide is urgently needed to improve resource allocation and clinical management.

Strangulation as an Acquired Brain Injury in Intimate-Partner Violence and Its Relationship to Cognitive and Psychological Functioning: A Preliminary Study

OBJECTIVE

The aim of this work was to examine the relationship between strangulation-related alterations in consciousness (AIC) and cognitive and psychological outcomes in women who have experienced intimate partner violence (IPV).

SETTING

Participants were recruited from a variety of settings, including women's shelters and support programs.

PARTICIPANTS

A total of 99 women were enrolled in the study. After applying exclusion criteria for factors that could mask or confound the effects of strangulation, 52 women remained for analyses.

DESIGN

Cross-sectional, retrospective.

MAIN MEASURES

We used several cognitive measures to assess learning, long-term and working memory, visuomotor speed, cognitive flexibility, and nonverbal cognitive fluency as well as several psychological measures to assess posttraumatic stress symptomatology, general distress, worry, anhedonic depression, and anxious arousal. We also used the Brain Injury Severity Assessment interview to examine the association between strangulation-related AICs and these measures of cognitive and psychological functioning.

RESULTS

Women who had experienced strangulation-related AICs performed more poorly on a test of long-term memory (P < .03) and had higher levels of depression (P < .03) and posttraumatic stress symptomatology (P < .02) than women who had not experienced strangulation-related AIC. When controlling for potential confounding variables, including number of IPV-related traumatic brain injuries, women who had experienced strangulation also performed more poorly on a measure of working memory.

CONCLUSION

This is the first report to assess strangulation in this manner and demonstrate links to cognitive and psychological functioning. These preliminary data contribute to our knowledge of strangulation and its effects on women who have experienced IPV.
