The Role of PTSD in Bi-directional Intimate Partner Violence in Military and Veteran Populations: A Research Review

Screening for Intimate Partner Violence Experience and Use in the Veterans Health Administration

Importance

The practice of screening women for intimate partner violence (IPV) in health care settings has been a critical part of responding to this major public health problem. Yet, IPV prevention would be enhanced with detection efforts that extend beyond screening for IPV experiences to identifying those who use violence in relationships as well.

Objective

To determine rates of IPV experiences and use (ie, among perpetrators of IPV) and factors associated with disclosures among adult patients seeking mental health services at the Veterans Health Administration.

Design, Setting, and Participants

This cross-sectional study used electronic medical record data drawn from a quality improvement initiative at 5 Veterans Health Administration medical centers conducted between November 2021 and February 2022 to examine IPV disclosures following concurrent screening for IPV experience and use. Participants included patients engaged in mental health services. Data were analyzed in April and May 2023.

Exposure

Mental health clinicians were trained to screen for IPV experience and use concurrently and instructed to screen all patients encountered through routine mental health care visits during a 3-month period.

Main Outcomes and Measures

Outcomes of interest were past-year prevalence of IPV use and experience, sociodemographic characteristics, and clinical diagnoses among screened patients.

Results

A total of 200 patients were offered IPV screening. Of 155 participants (mean [SD] age, 52.45 [15.65] years; 124 [80.0%] men) with completed screenings, 74 (47.7%) denied past-year IPV experience and use, 76 (49.0%) endorsed past-year IPV experience, and 72 (46.4%) endorsed past-year IPV use, including 67 participants (43.2%) who reported IPV experience and use concurrently; only 9 participants (5.8%) endorsed unidirectional IPV experiences and 5 participants (3.2%) endorsed unidirectional IPV use. Patients who reported past-year IPV experience and use were younger than those who denied IPV (experience: mean difference, -7.34 [95% CI, 2.51-12.17] years; use: mean difference, -7.20 [95% CI, 2.40-12.00] years). Patients with a posttraumatic stress disorder diagnosis were more likely to report IPV use (43 patients [59.7%]) than those without a posttraumatic stress disorder diagnosis (29 patients [40.3%]; odds ratio, 2.14; [95% CI, 1.12-4.06]). No other demographic characteristics or clinical diagnoses were associated with IPV use or experience.

Conclusions and Relevance

In this cross-sectional study of IPV rates and associated factors, screening for IPV found high rates of both IPV experience and use among patients receiving mental health care. These findings highlight the benefit of screening for IPV experience and use concurrently across gender and age. Additionally, the associations found between PTSD and IPV use underscore the importance of strengthening and developing additional targeted treatment for IPV.

What do the Public Understand About Intimate Partner Violence in the Context of Military Veteran Status and PTSD?

Intimate Partner Violence (IPV) represents a significant public and social health concern and may present particular complexities in military veteran relationships which are subject to unique stressors including separations, transition to civilian life and increased risk of Post-Traumatic Stress Disorder (PTSD). Public understanding is vital in terms of ensuring access to services and appropriate intervention. However, little is known about the public perception of IPV in this context. This study sought to assess how public recognition and discourse is affected by military veteran status and a diagnosis of PTSD. Community participants (N = 269) were randomly allocated to one of four conditions and presented with a story containing IPV in which the profession (military veteran/civilian worker) and diagnostic status (PTSD/No PTSD) were manipulated. All participants rated the extent to which they felt the story contained IPV; additionally, half (n = 123) took part in a story completion task designed to elicit qualitative data with regards to public discourse. The mean scores in all conditions were weighted towards IPV recognition. Results indicated a small interaction between job role and PTSD (F[1265] = 7.888, p < 0.01, partial n² = 0.029) meaning that the public are more likely to recognise IPV when it is perpetrated by a military veteran than a civilian with PTSD. Diagnostic status made no difference to recognising abuse perpetrated by a military veteran. However, the fit of the model was weak (r² = .040) meaning that the large majority of variance was due to factors not accounted for. Qualitative findings indicated that in a military population trauma may be assumed even where not indicated and the public appear less likely to consider current stressors or acknowledge that PTSD cannot justify abuse. Victims of IPV in military relationships may therefore be particularly vulnerable to discourses that prioritise the victim status of the perpetrator.

Neurobiology of Aggression-Review of Recent Findings and Relationship with Alcohol and Trauma

Aggression can be conceptualized as any behavior, physical or verbal, that involves attacking another person or animal with the intent of causing harm, pain or injury. Because of its high prevalence worldwide, aggression has remained a central clinical and public safety issue. Aggression can be caused by several risk factors, including biological and psychological, such as genetics and mental health disorders, and socioeconomic such as education, employment, financial status, and neighborhood. Research over the past few decades has also proposed a link between alcohol consumption and aggressive behaviors. Alcohol consumption can escalate aggressive behavior in humans, often leading to domestic violence or serious crimes. Converging lines of evidence have also shown that trauma and posttraumatic stress disorder (PTSD) could have a tremendous impact on behavior associated with both alcohol use problems and violence. However, although the link between trauma, alcohol, and aggression is well documented, the underlying neurobiological mechanisms and their impact on behavior have not been properly discussed. This article provides an overview of recent advances in understanding the translational neurobiological basis of aggression and its intricate links to alcoholism and trauma, focusing on behavior. It does so by shedding light from several perspectives, including in vivo imaging, genes, receptors, and neurotransmitters and their influence on human and animal behavior.

Male Sexual Health Related Complications Among Combat Veterans

INTRODUCTION

With improved armor and combat trauma care, more male service members in the 21st century are surviving devastating injuries to their genitourinary (GU) system. The impact of these injuries can have long lasting effect on their sexual function and fertility status.

OBJECTIVES

To review the current literature on sexual health-related complications and fertility implications among male service members sustaining combat related injuries.

METHODS

We performed a literature search that included male sexual health complications and combat injuries using PubMed and Google Scholar. We reviewed the impact of traumatic injuries to the pelvis and perineum on sexual function and fertility, and we also discuss sexual dysfunction from posttraumatic stress disorder (PTSD) and traumatic brain injuries (TBI).

RESULTS

Injuries sustained during combat are usually polytraumatic, especially in recent conflicts with improvised explosive devices. The majority of GU combat injuries involve the scrotum, testes, and penis resulting in lasting structural dysfunction. PTSD is associated with higher levels of erectile dysfunction, hypoactive sexual desire, and premature ejaculation. Overall, veterans diagnosed with PTSD had a higher risk of developing sexual dysfunction. Veterans with TBI experience sexual health complications, such as decreased libido, difficulties with arousal maintenance, and the ability to achieve orgasm. Combat related injuries can have significant fertility implications on service members as they typically serve in their peak fertility years.

CONCLUSIONS

Traumatic GU injuries, PTSD, TBI, and associated endocrine dysfunction can all contribute to sexual dysfunction among combat veterans. Given the complex nature of sexual dysfunction in this population, these patients are best managed by a multidisciplinary team. Castillo O, Chen IK, Amini E, et al.

Comparing post-Gulf War and post-9/11 era of service among veterans: Intimate partner violence and substance use by race and ethnicity

Using structural equation modeling to examine intimate partner violence (IPV) among post-Gulf War and post-9/11 military families, this study considers variations of IPV from the point of the perpetrator to test the impact of demographic factors on the type of IPV most prevalent among military perpetrators. The study sample contains information about 449 male veterans from the National Longitudinal Study of Adolescent to Adult Health (1994-2008): Waves I and IV in-home interviews. Study findings indicate that the perpetration of physical and sexual IPV depends on the context of veteran cohort and race/ethnicity.

Psychological Predictors of Sexual Intimate Partner Violence against Black and Hispanic Women

Background: Although various types of intimate partner violence (IPV) tend to co-occur, risk factors of each type of IPV may differ. At the same time, most of the existing literature on risk factors of IPV among minorities has used a cross-sectional design and has focused on physical rather than sexual IPV. We conducted the current study to compare Black and Hispanic women for psychological predators of change in sexual IPV over time. Methods: Using data from the Fragile Families and Child Wellbeing Study (FFCWS), this study followed 561 Black and 475 Hispanic women with their male partners for four years. Independent variables included male partners' depression, anxiety, problem alcohol use, and male-to-female physical and psychological IPV perpetration. The dependent variable was sexual IPV reported by female partners, measured at baseline, two years, and four years later. Covariates included age, income, marital status and educational level. We used a multi-group latent growth curve model (LGCM) to explain intercept, linear, and quadratic slopes, which represent the baseline, and linear and curvilinear trajectories of male-to-female sexual IPV, where groups were defined based on ethnicity. Results: Psychological IPV was associated with sexual IPV at baseline among both ethnic groups. The male partner's depression was a risk factor for an increase in sexual IPV over time among Black but not Hispanic women. Anxiety, problem alcohol use and physical IPV did not have an effect on the baseline or change in sexual IPV over time. Psychological IPV was not associated with an increase in sexual IPV over time in either ethnic groups. Conclusions: There is a need for screening of sexual IPV in the presence of psychological IPV among minority women. There is also a need for screening and treatment of male partners' depression as a strategy to reduce sexual IPV among Black women.
