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

The Intersection of Intimate Partner Violence, Strangulation, and Brain Injury Screening: A Pilot Project

BACKGROUND

Survivors of intimate partner violence are at a high risk for having a brain injury because of high rates of strangulation and head and face injuries sustained from physical abuse. In addition to acute physical injuries, survivors experience various health complications.

PROBLEM

Many survivors do not seek medical attention for their injuries, and when they do, their brain injury often goes unrecognized and untreated. Research indicates that screening for brain injury can be an effective intervention to increase the identification of brain injuries and medical referrals for diagnosis and treatment. Unfortunately, brain injury screening is not a standard of care.

METHODS

Shelter-seeking clients were routinely screened for brain injury using a modified HELPS screening tool. A positive screen prompted a medical referral.

INTERVENTION

A modified HELPS screening tool was utilized with permission for the project.

RESULTS

Before implementation, 36 individuals entered shelter, 0 were screened for brain injury, and the medical referral rate was 19.4% (n = 7). After implementation, 40 clients entered shelter, 36 were screened for brain injury, 77.8% (n = 28) screened positive, and the medical referral rate was 80.6% (n = 29).

CONCLUSIONS

Brain injury screening may be an effective evidence-based intervention for shelter-seeking survivors of intimate partner violence to increase medical referrals.

Systematic review and data synthesis on the treatment of sexual violence victimization by an intimate partner

This study aims to conduct a systematic review and synthesis on the treatment of sexual violence victimization by an intimate partner evaluating specifically the impact of treatment on mental health outcomes of female sexual intimate partner violence (IPV) survivors. We followed the Cochrane Handbook for Systemic Reviews of Interventions guidelines for the process of conducting systematic reviews. We were unable to conduct meta-analyses due to the substantial heterogeneity of the interventions for IPV. A qualitative summary of 6 controlled studies identified no benefit to the treatment of sexual coercion, posttraumatic stress disorder, depression, or anxiety for female sexual IPV survivors. However, we are limited by a paucity of data for each outcome on this subject. In conclusion, sexual coercion is a complex issue that has adverse effects on mental health and the well-being of the survivors. More research is needed that investigates what kind of interventions are effective for this specific population.

Structural brain morphology in young adult women who have been choked/strangled during sex: A whole-brain surface morphometry study

INTRODUCTION

Being choked/strangled during partnered sex is an emerging sexual behavior, particularly prevalent among young adult women. Using a multiparameter morphometric imaging approach, we aimed to characterize neuroanatomical differences between young adult women (18-30 years old) who were exposed to frequent sexual choking and their choking naïve controls.

METHODS

This cross-sectional study consisted of two groups (choking [≥4 times in the past 30 days] vs. choking-naïve group). Participants who reported being choked four or more times during sex in the past 30 days were enrolled in the choking group, whereas those without were assigned to the choking naïve group. High-resolution anatomical magnetic resonance imaging (MRI) data were analyzed using both volumetric features (cortical thickness) and geometric features (fractal dimensionality, gyrification, sulcal depth).

RESULTS

Forty-one participants (choking n = 20; choking-naïve n = 21) contributed to the final analysis. The choking group showed significantly increased cortical thickness across multiple regions (e.g., fusiform, lateral occipital, lingual gyri) compared to the choking-naïve group. Widespread reductions of the gyrification were observed in the choking group as opposed to the choking-naïve group. However, there was no group difference in sulcal depth. The fractal dimensionality showed bi-directional results, where the choking group exhibited increased dimensionality in areas including the postcentral gyrus, insula, and fusiform, whereas decreased dimensionality was observed in the bilateral superior frontal gyrus and pericalcarine cortex.

CONCLUSION

These data in cortical morphology suggest that sexual choking events may be associated with neuroanatomical alteration. A longitudinal study with multimodal assessment is needed to better understand the temporal ordering of sexual choking and neurological outcomes.

Systematic Investigation of Meta-Analysis Data on Treatment Effectiveness for Physical, Psychological, and Sexual Intimate Partner Violence Perpetration

Intimate partner violence can lead to physical, economical, mental, and sexual well-being issues, and even death, and it is most commonly experienced by women. There exist a number of treatment models for the prevention and treatment of intimate partner violence (IPV). In this study, we provided a comprehensive meta-regression analysis of the effectiveness of batterer treatment programs, with a view to characterizing the interplay between different forms of IPV (physical, psychological, and sexual). Using meta-regression, we explore the effect sizes and whether IPV treatment methods have distinct impacts on the outcomes. We use the difference normalized by pretreatment mean and variance foldchange to uncover the relationship between different violence subtypes and how they drive each other. Specifically, our study found that studies with more pre-treatment psychological and/or sexual violence, lead to less favorable outcomes while the studies that start with more physical violence are able to demonstrate their effects more effectively. Results of this study can be used to help the clinician effectively select the treatment for the perpetrator based on the violence type and severity of violence in order to more effectively treat the needs for each specific relationship.

Do Gender Differences Exist Among Victims of Head and Neck Injuries due to Intimate Partner Violence?

PURPOSE

The frequency of intimate partner violence (IPV) is much lower in males than females. Data regarding IPV-related injuries patterns and characteristics in males are scant. The purpose of this study was to characterize and compare patterns of IPV-related head and neck injuries between men and women.

MATERIALS AND METHODS

This cross-sectional study reviewed cases of IPV at Grady Memorial Hospital in Atlanta, Georgia from January 2016 to August 2019. The study sample was collected from electronic medical records by identifying IPV subjects using a natural language processing algorithm and then cross-referencing the trauma registry to identify patients who sustained head and neck injuries. The primary analyses of interest were to measure the association between gender and the following covariates: age, race, insurance status, setting of injury, day of injury, social history, report of physical abuse, mechanism of injury, injury location, brain injuries, soft tissue injuries, facial fractures, other associated injuries, Glasgow Coma Scale, Injury Severity Score, hospital length of stay, intensive care unit length of stay, and discharge status. Univariate and bivariate analyses were calculated. Statistical significance was P < .05.

RESULTS

One hundred fifty six patients met inclusion criteria. There were 120 (76.9%) female patients with a mean age of 34.5 years (range, 16 to 67 years). There were 36 (23%) male patients with a mean age of 43.8 years (range, 18 to 77 years). Women were statistically more likely than men to have government-subsidized insurance (47 [39.2%] vs 7 [19.4%]; P = .03), positive alcohol exposure (27 [22.5%] vs 19 [52.8%]; P = .0001), positive illicit drugs toxicology screen (25 [20.8%] vs 13 [36.1%]; P < .02), report physical abuse (24 [20%] vs 0; P = .004), have subarachnoid hemorrhage (14 [11.7%] vs 0; P = .04), and/or lower extremity injuries (39 [32.5%] vs 5 [13.9%]; P = .03).

CONCLUSION

Males tend not to report physical abuse; this behavior contributes to IPV under-reporting in males.
