Scoping review of the role of social support in women veterans' psychosocial and health outcomes

Women veterans are a steadily growing population and have unique military experiences (e.g., report high rates of sexual harassment and assault) that are impactful across the lifespan. High levels of positive social support have been linked to a range of positive outcomes in both civilian and military populations. However, research has not consistently explored social support and interpersonal functioning in women veterans, or as potential mechanisms of change within interventions for women veterans. This is a scoping review of peer-reviewed articles that evaluated social support. Articles with at least 10% women or formally evaluated sex or gender in reference to social support were included. A total of 69 studies evaluated social support in relation to women veterans' health outcomes. From a biopsychosocial perspective, social support is an important construct to examine relative to health care engagement and response. Limited research considered aging women veterans needs or focused on the intersectional identities of women veterans. Positive social support can have major physical and mental health benefits, yet limited research and disparate methodological approaches minimize the ability to draw conclusions on how social support can best be leveraged to support women veterans. Women veterans' roles and military experiences (e.g., increased likelihood of combat exposure) are changing and this population is aging. Research is needed to inform best practices for this growing segment of the veteran population.

Institutional Betrayal and Closeness Among Women Veteran Survivors of Military Sexual Trauma: Associations with Self-Directed Violence and Mental Health Symptoms

Institutional betrayal is defined as harm caused by an institution to an individual in the context of trust and dependence. High institutional betrayal is associated with poorer health outcomes, and high levels of trust, dependence, or identification with the institution (institutional closeness) may exacerbate the negative effects of institutional betrayal. While military sexual trauma is prevalent among women Veterans and associated with high rates of institutional betrayal, studies of the impact of military sexual trauma-related institutional betrayal have been limited in size and scope and have not examined the potential role of institutional closeness. We conducted a secondary analysis of national survey data collected from women Veterans who screened positive for military sexual trauma (n = 229). Hierarchical logistic and linear regression were used to examine associations between predictor variables (institutional betrayal, institutional closeness, and their interaction) and outcomes of interest and adjusted for age, education, and military sexual assault history. Institutional betrayal was associated with increased odds of suicidal ideation and suicide attempt during or following military service, as well as more severe symptoms of depression and posttraumatic stress disorder (PTSD). Institutional betrayal was not associated with non-suicidal self-injury or lifetime substance misuse. Counter to hypotheses, institutional closeness did not moderate relationships between institutional betrayal and mental health symptoms or self-directed violence. Results underscore the necessity of preventing and addressing institutional betrayal among women Veterans who experience military sexual trauma.

A Literature Review of Mental Health Symptom Outcomes in U.S. Veterans and Servicemembers Following Combat Exposure and Military Sexual Trauma

Combat exposure (CE) and military sexual trauma (MST) are among the most common types of traumatic experiences faced by veterans and active duty servicemembers and, as such, have both garnered increased research focus over the past decades. However, there has not yet been a critical review of the literature to examine the distinct clinical presentations associated with different trauma types. This is particularly important, as understanding distinct clinical profiles could help researchers and clinicians refine treatment approaches based on trauma type. To address this question, we conducted a search of the available literature in PsycINFO and PubMed prior to October 2022. We identified 43 articles evaluating the distinct and overlapping clinical symptoms of CE and MST. Study findings were conceptually organized by psychiatric condition. In general, there was substantial variability in study methodology including sample size, composition, and operationalizations of CE and MST. Despite this variability, notable patterns emerged across studies. Specifically, MST and CE uniquely predicted posttraumatic stress disorder symptoms, MST was more related to depressive symptoms and suicidality than CE, and CE appeared to be more related to alcohol use and other externalizing behaviors. Gender also played a significant role in the relationship between CE, MST, and clinical variables across studies. This review suggests that individuals with a history of MST and CE likely have distinct clinical presentations and more research into these presentations could better inform assessment and treatment. Important methodological gaps in the literature are also discussed.

The Role of Unit and Interpersonal Support in Military Sexual Trauma and Posttraumatic Stress Disorder Symptoms

Military sexual trauma (MST) is strongly associated with posttraumatic stress disorder (PTSD). Among many potential factors explaining this association are unit and interpersonal support, which have been explored in few studies with veterans who have experienced MST. This project examines unit and interpersonal support as moderators and/or mediators of PTSD symptoms among post-9/11 Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans who experienced MST. MST, unit support, and interpersonal support variables were collected at Time 1 (T1; N = 1,150, 51.4% women), and PTSD symptoms 1 year later at Time 2 (T2; N = 825; 52.3% women). Given gender differences in endorsed MST, models with the full sample (men and women) and women only were examined, while controlling for covariates related to PTSD, and a path model was examined among women veterans. Mediation was supported in the full model and women-only models, with the combination of both mediators demonstrating the strongest mediation effects (full-model: β = .06, 95% confidence interval [CI] [0.03, 0.10], p < .001; women-only model: β = .07, [0.03, 0.14], p = .002). Among the women-only model, MST was negatively associated with unit support (β = -.23, [-0.33, -0.13], p < .001) and interpersonal support (β = -.16, [-0.27, -0.06], p = .002) and both support types were negatively associated with PTSD symptoms (unit support: β = -.13, [-0.24, -0.03], p = .014; interpersonal support: β = -.25, [-0.35, -0.15], p < .001). Moderation was not supported in the full model nor in the women-only model. Experiencing MST is associated with receiving less unit and/or interpersonal support, which in turn is associated with greater PTSD symptoms. More work is needed to understand and improve the impact of unit and community responses to MST on service members who experience MST.

Moral Injury as a Mediator of the Associations Between Sexual Harassment and Mental Health Symptoms and Substance Use Among Women Veterans

Moral injury is an array of symptoms theorized to develop in response to morally injurious events, defined as events that challenge one's core moral beliefs and expectations about the self, others, and world. Recent measures of moral injury have distinguished self-directed moral injury (e.g., moral injury symptoms that emerge following the perpetration of morally injurious events) from other-directed moral injury, the symptoms of which are believed to stem from one's response to actions that others have committed (e.g., within-rank violence, failures of leadership, and acts of betrayal committed by trusted others or institutions). Using a convenience sample of 154 primarily former military women, the present study examined if other-directed moral injury symptoms (e.g., anger, betrayal, and mistrust) associated with military experience would mediate the association between military sexual harassment and mental health and substance abuse symptoms. Results demonstrated that 85.8% (n = 127) of the of this sample of women veterans reported experiencing sexual harassment during their military service. Using a single mediation model, we further demonstrated that other-directed moral injury mediated the association between sexual harassment experience and mental health symptoms. Given the percentage of women veterans who reported sexual harassment, these results suggest that additional training for military members, and particularly, military leaders, is necessary to begin to reduce sexual harassment. In addition, mental health providers who work with current and former military members should consider how other-directed moral injury may be associated with mental health symptoms among women veterans who have experienced sexual harassment while in the military.

Assessing Institutional Betrayal Among Female Veterans Who Experienced Military Sexual Trauma: A Rasch Analysis of the Institutional Betrayal Questionnaire.2

Military sexual trauma (MST; i.e., sexual harassment and/or sexual assault during one's military service) is highly prevalent among female veterans and is associated with numerous adverse health and psychosocial sequelae. When institutions fail to prevent sexual trauma from happening or respond in an unsupportive manner (i.e., institutional betrayal [IB]), MST survivors typically report more severe health-related outcomes. Although the Institutional Betrayal Questionnaire.2 (IBQ.2) was developed to assess IB, no studies have examined the factor structure or dimensionality of the IBQ.2 among MST survivors. In addition, initial research has reported differing factor structures for this measure. The present study examined the dimensionality and factor structure of the IBQ.2, and tested for differential item functioning (DIF) based on whether military sexual assault was experienced. The sample comprised 235 female veterans who reported a history of MST in an anonymous national survey. Rasch analysis suggested multidimensionality and DIF based on history of military sexual assault. Exploratory factor analysis and parallel analysis suggested the IBQ.2 comprises three factors: (1) Environment Leading to MST, (2) Institutional Response to MST, and (3) Institutional Belongingness following MST. Although these results suggest that the IBQ.2 is multidimensional, the three-factor model had significant issues with respect to dimensionality, item fit, and person separation and reliability. Thus, using the full IBQ.2 may be more advantageous. Further examination of the IBQ.2 is warranted to ensure optimal assessment of IB in relation to MST, irrespective of whether the MST comprised sexual harassment or sexual assault, as well as to ensure that the IBQ.2 is culturally meaningful for MST survivors.

A sex-stratified analysis of suicidal ideation correlates among deployed post-9/11 veterans: Results from the survey of experiences of returning veterans

BACKGROUND

Suicide rates are higher among veterans than non-veterans; this difference is particularly salient for females. Knowledge is sparse regarding correlates of suicidal ideation (SI) among female veterans, particularly in non-VHA samples. As such, and given that SI confers a strong risk for subsequent suicidal behavior, this study aimed to: (1) compare prevalence of recent SI by sex; and (2) determine whether deployment stressors, mental health symptoms, and recent psychosocial stressors are associated with recent SI, by sex, among post-9/11 veterans.

METHODS

A sex-stratified analysis of cross-sectional data from 809 post-9/11, deployed veterans was conducted using the Survey of Experiences of Returning Veterans (SERV); statistical interactions between sex and correlates of interest were assessed.

RESULTS

Self-reported prevalence of recent SI did not differ by sex. A statistically significant interaction between sex and combat was observed; greater combat experience was associated with increased SI for females only. While significant interactions were not observed for other correlates, differences in significant predictors and predictor effect sizes were noted across sex-stratified models. Recent housing and financial concerns were only associated with increased SI prevalence among females, whereas concern about other recent stressful life events was associated with increased SI prevalence only among males.

LIMITATIONS

This is a cross-sectional analysis of a national survey with limited power to detect statistical sex interactions.

CONCLUSIONS

While correlates of SI are relatively consistent for males and females notable differences suggest that tailored assessment and intervention based on sex may hold merit in mitigating SI among post-9/11 era Veterans.

Meaningful military engagement among male and female post-9/11 veterans: An examination of correlates and implications for resilience

OBJECTIVE

Post-9/11 military deployment is commonly reported as stressful and is often followed by psychological distress after returning home. Yet veterans also frequently report experiencing meaningful military engagement (MME) that may buffer detrimental effects of military stressors. Focusing on the under-investigated topic of association of MME with post-deployment psychological adjustment, this study tests gender differences in MME and post-deployment outcomes.

METHOD

This cross-sectional study examined the relationship of MME with deployment stressors, subsequent psychological distress (posttraumatic stress symptoms (PTSS) and depression), and gender among 850 recent-era U.S. veterans (41.4% female).

RESULTS

On average, both male and female veterans reported high MME. Greater MME was associated with less PTSS and depression following combat and general harassment, and more depression after sexual harassment. For men only, MME associated with less PTSS after sexual harassment.

CONCLUSIONS

MME is high among post-9/11 veterans, but its stress-buffering effects depend on gender and specific stressor exposure.

A Dyadic Analysis of PTSD and Psychological Partner Aggression Among U.S. Iraq and Afghanistan Veterans: The Impact of Gender and Dual-Veteran Couple Status

Posttraumatic stress disorder (PTSD) symptoms have been repeatedly linked to intimate partner aggression (IPA), and previous research has suggested that this association may be stronger among veterans and men. However, few studies have examined veteran status and gender as moderators of the association between PTSD and psychological IPA, taking both partners' perspectives into account (i.e., within a dyadic framework). The current study aimed to address this limitation by using dyadic multilevel modeling to examine the association between PTSD symptoms and psychological IPA perpetration among a sample of 159 Operation Iraqi Freedom and Operation Enduring Freedom veterans and their partners (N = 318 participants). Findings revealed that both one's own and one's partner's PTSD symptoms were positively associated with greater psychological IPA. In addition, the effects of partner PTSD symptoms on psychological IPA perpetration differed across gender and veteran status. Results suggested that the association of partner PTSD and IPA perpetration may be stronger for male veterans than for female veterans. Findings from the current study are consistent with previous research showing associations between PTSD and IPA, and have clinical implications for treatment of PTSD and IPA among Operation Iraqi Freedom and Operation Enduring Freedom veterans.

Examining moderators of the relationship between social support and self-reported PTSD symptoms: A meta-analysis

Social support is one of the most robust predictors of posttraumatic stress disorder (PTSD). Yet, little is known about factors that moderate the relationship between social support and PTSD symptom severity. This meta-analysis estimated the overall effect size of the relationship between self-reported social support and PTSD severity and tested meaningful demographic, social support, and trauma characteristics that may moderate this association using both cross-sectional and longitudinal effect sizes. A comprehensive search identified 139 studies with 145 independent cross-sectional effect sizes representing 62,803 individuals and 37 studies with 38 independent longitudinal effect sizes representing 25,792 individuals. Study samples had to comprise trauma-exposed, nonclinical adult populations to be included in the analysis. Cross-sectional and longitudinal analyses revealed a near medium overall effect size (rcross = -.27; 95% CI [-.30, -.24]; rlong = -.25; 95% CI [-.28, -.21]) with a high degree of heterogeneity (cross-sectional I2 = 91.6, longitudinal I2 = 86.5). Both cross-sectional and longitudinal moderator analyses revealed that study samples exposed to natural disasters had a weaker effect size than samples exposed to other trauma types (e.g., combat, interpersonal violence), studies measuring negative social reactions had a larger effect size than studies assessing other types of social support, and veteran samples revealed larger effect sizes than civilian samples. Several other methodological and substantive moderators emerged that revealed a complex relationship between social support and PTSD severity. These findings have important clinical implications for the types of social support interventions that could mitigate PTSD severity. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Self-reported PTSD symptoms and social support in U.S. military service members and veterans: a meta-analysis

Background: The mental health burden of posttraumatic stress disorder (PTSD) is high in U.S. military samples. Social support is one of the most robust protective factors against PTSD and a recent meta-analysis indicates that this relationship is even stronger in military samples compared to civilian samples. Yet no meta-analyses have explored factors impacting this association in veterans and military service members (VSMs). Objective: The current meta-analysis examined demographic, social support, and military characteristics that may moderate the relationship of PTSD severity and social support among U.S. VSMs. Method: A search identified 37 cross-sectional studies, representing 38 unique samples with a total of 18,766 individuals. Results: The overall random effects estimate was -.33 (95% CI: -.38, -.27, Z = -10.19, p <.001), indicating that lower levels of social support were associated with more severe PTSD symptoms. PTSD measures based on the Diagnostic and Statistical Manual (DSM)-III had a larger effect size than measures based on DSM-IV or DSM-5. The social support source was a significant moderator such that support perceived from non-military sources was associated with a larger effect size than support perceived from military sources. This finding held after accounting for covariates. Deployment-era, timing of social support, and age were also significant moderators, but were no longer significantly associated with effect size after adjusting for covariates. Although previous meta-analyses have shown social negativity to be more impactful than positive forms of social support, there were too few studies conducted to evaluate social negativity in moderator analyses. Conclusion: Results suggest that social support received from civilians and in the home environment may play a greater protective role than social support received from military sources on long-term PTSD symptom severity. The literature on social support and PTSD in U.S. VSMs would be strengthened by studies examining the association of social negativity and PTSD symptoms.

Military sexual trauma among women Veterans: The buffering effect of coworker support

Prior research has demonstrated the impact of military sexual trauma (MST) on health and well-being. However, little empirical work has been published identifying protective factors for women who have experienced MST. We examined the impact of two different forms of MST, harassment-only and assault MST, on PTSD symptoms and social functional impairment in a sample of women Veterans employed in the civilian workforce. The effects of MST were examined at three different times over a period of 9 months. We found that MST that included both harassment and assault was associated with significantly higher levels of PTSD symptoms and social functional impairment across three different time points among women Veterans employed in civilian jobs. Further, the pattern of results suggested that coworker support can buffer against these negative outcomes experienced by women who reported assault MST. Overall, findings suggest that coworker support is one critical resource for women Veterans who experienced assault MST.

Military Sexual Trauma in Older Women Veterans: Prevalence and Comorbidities

BACKGROUND

Recent attention has highlighted the common occurrence and health consequences of military sexual trauma (MST) in younger women veterans. However, almost nothing is known about MST in older veterans.

OBJECTIVE

To describe MST among older women veterans, including prevalence and common comorbidities.

DESIGN

Cross-sectional observational study, using data from national Department of Veterans Affairs medical records.

PARTICIPANTS

Population-based sample of women Veterans aged 55+ with at least one documented MST screen response and at least one clinical encounter in fiscal years 2005-2015.

MAIN MEASURES

MST screen: medical diagnoses (diabetes, hypertension, hyperlipidemia, myocardial infarction, cerebrovascular disease, congestive heart failure, obesity, chronic pain conditions, back pain, dementia, insomnia, sleep apnea, menopause symptoms) and mental health diagnoses (anxiety, depression, posttraumatic stress disorder, tobacco use, alcohol use disorder, substance use disorder, opioid use disorder, suicidal ideation) from International Classification of Diseases, Ninth Revision Clinical Modification codes in the medical record.

KEY RESULTS

In this cohort of older women veterans (n = 70,864, mean age 65.8 ± 10.4 years), 13% had a positive MST screen. In multivariable regression analyses adjusted for age, race/ethnicity, and marital status, MST was strongly associated with most mental health diagnoses, particularly posttraumatic stress disorder (OR 7.25, 95% CI 6.84-7.68), depression (OR 2.39, 95% CI 2.28-2.50), and suicidal ideation (OR 2.42, 95% CI 2.08-2.82). MST was also associated with multiple medical conditions, particularly sleep disorders (insomnia OR 1.61, 95% CI 1.43-1.82; sleep apnea OR 1.48, 95% CI 1.37-1.61) and pain (chronic pain OR 1.58, 95% CI 1.50-1.67; back pain OR 1.40, 95% CI 1.34-1.47).

CONCLUSIONS

A history of MST is common among older women veterans and associated with a range of medical and mental health diagnoses. These findings call attention to the need for additional research in this understudied population, and the importance of trauma-informed care approaches for women across the lifespan.

Meaning in life following deployment sexual trauma: Prediction of posttraumatic stress symptoms, depressive symptoms, and suicidal ideation

Deployment sexual trauma (DST; i.e., sexual harassment or assault during deployment in the military) is associated with physical and mental health consequences, including posttraumatic stress disorder (PTSD), depression, and suicidal ideation (SI). Less attention has been placed on factors that may offer protection from deleterious mental health outcomes following DST. Global meaning in life (i.e., purpose, beliefs, goals, and subjective feelings) has been shown to be a protective factor against PTSD, depression, and SI following combat trauma; however, the extent to which meaning in life may affect outcomes following DST has not been investigated. Cross-sectional associations and Hayes mediation models were examined using baseline interview data from the Survey of Experiences of Returning Veterans sample (SERV; 850 recently returned veterans, 352 women). DST was associated with post-deployment posttraumatic stress symptoms (PTSS), depressive symptoms, and SI severity, and with decreased sense of meaning in life. Further, meaning in life was a significant mediator between DST and each of the three outcomes, even after controlling for demographic variables and combat experiences. The mediation models did not differ by gender. Findings suggest meaning in life may be an important clinical factor, both for the identification of risk and as a point of intervention.

Administrative Military Discharge and Suicidal Ideation Among Post-9/11 Veterans

INTRODUCTION

From 2005 to 2016, the Veteran suicide rate increased 25.9%. Reducing this rate is a top priority for the Department of Veterans Affairs. In 2017, a policy change expanded emergent mental health services to include previously ineligible Veterans discharged under other than honorable conditions. To date, research examining the relationship between military discharge type and suicide risk has been limited.

METHODS

This study aimed to examine the association between discharge type (honorable versus administrative) and active suicide ideation among Veterans participating in the Survey of Experiences of Returning Veterans (N=850, data collection 2012-2015 and data analysis 2017-2018) using logistic regression. Stratified analyses explored whether gender, time since military separation, or recent mental health service use moderated this relationship.

RESULTS

The prevalence of suicide ideation was significantly higher (p<0.01) among Veterans reporting administrative discharge (23.1%, 95% CI=12.8, 33.3 vs 10.6%, 95% CI=8.4, 12.8). However, after accounting for lifetime suicide attempt history, combat experiences, posttraumatic stress disorder symptoms, depression, and drug dependence, discharge was no longer associated with suicide ideation. Recent mental health service use and time since separation significantly modified this relationship. The relationship was only significant among Veterans not using mental health services (OR=4.8, 95% CI=1.3, 18.2) and among transitioning Veterans <2years from separation (OR=3.6, 95% CI=1.4, 9.2).

CONCLUSIONS

These findings suggest that recognized risk factors for suicide, such as a history of mental health conditions, account for the increased prevalence of suicide ideation among Veterans with administrative discharges and that mental health services may have the potential to mitigate such risk in this high-risk Veteran population.

Do unit and post-deployment social support influence the association between deployment sexual trauma and suicidal ideation?

Deployment sexual trauma is associated with post-deployment suicidal ideation. No studies have examined the role of social support in this association. The present study examined if perceived unit support and post-deployment support influenced the association between deployment sexual trauma and suicidal ideation. 824 post-9/11 veterans (480 men, 344 women) from the Survey of Experiences of Returning Veterans completed the Deployment Risk and Resilience Inventory-2 and Columbia-Suicide Severity Rating Scale. Age, possible depression, posttraumatic stress disorder symptoms, and lifetime suicide attempt were covaried. Among men, post-deployment support moderated the association between deployment sexual trauma and suicidal ideation; deployment sexual trauma predicted suicidal ideation only for men reporting low post-deployment support. Among women, post-deployment support mediated the association between deployment sexual trauma and suicidal ideation. Unit support neither moderated nor mediated the association between deployment sexual trauma and suicidal ideation. Among men who experience deployment sexual trauma, those with low perceived post-deployment support may be at particularly elevated risk for suicidal ideation and may benefit from more intensive monitoring and interventions that bolster social support. Increasing perceived post-deployment support for women who experience deployment sexual trauma is also warranted. Determining optimal ways to strengthen post-deployment support for sexual trauma survivors is essential.

Sexual Assault and Disabling PTSD in Active Duty Service Women

INTRODUCTION

Sexual assault in the military is a major concern and may result in significant health problems, such as post-traumatic stress disorder (PTSD). Those developing disabling PTSD symptoms may require a disability evaluation. We examined disability evaluation trends for service women with PTSD to better understand characteristics associated with inability to continue Active Duty service.

METHODS

This is a retrospective review of disability reports and electronic medical records for 322 Active Duty women diagnosed with and treated for PTSD by psychiatrists and psychologists at a large military treatment facility between 2011 and 2014. Service women requiring medical disability evaluation for PTSD (n = 159) were included in the study as "IDES cases" (Integrated Disability Evaluation System - IDES). A similar number of women, randomly selected from those seeking care for PTSD but not requiring disability evaluation during the same period, were included in the "control" group (n = 163). Analyzes done to evaluate differences between groups (IDES cases vs. controls) included demographic and service-related characteristics, history of chronic pain, and PTSD index trauma types, such as pre-military trauma and military sexual trauma (MST). Logistic regression was performed to identify the factors associated with inclusion in IDES.

RESULTS

MST was the most frequent PTSD index trauma in the IDES group (73.6% vs. 44.8% of control group) and the most significant factor associated with IDES inclusion (OR 2.6, p = 0.032). Those in the IDES group had significantly greater number of mental health visits for PTSD (IDES: m = 68.6 vs. controls: m = 29.6) and more frequent chronic pain history (IDES 40.9% vs. controls 19.6%) than those in the control group. Approximately 65% of women in both groups had a history of childhood abuse, but childhood abuse, as a PTSD index trauma, was negatively associated with IDES inclusion (OR 0.293, p = 0.006).

CONCLUSIONS

Active Duty service women with PTSD and a MST index trauma are much more likely to require disability evaluation (IDES) than those with PTSD due to other trauma types. IDES evaluation for conditions such as PTSD may result in early termination of military service and is a potential downstream consequence of MST. Service women requiring greater numbers of mental health visits for PTSD treatment may benefit from a multidisciplinary approach to treating concurrent health conditions, such as chronic pain. Those providing care for service women should evaluate for MST, chronic pain and pre-military trauma, such as childhood abuse; and aggressively treat these conditions to prevent PTSD and disability.
