The impact of killing in war on mental health symptoms and related functioning

Differential impact of type of killing on posttraumatic stress disorder symptoms in U.S. Army soldiers deployed to Afghanistan

Over the past 20 years, U.S. military conflicts in Iraq and Afghanistan have been marked by high rates of combat and wartime killings. Research on Vietnam-era service members suggests that the type of killing (i.e., killing a combatant vs. noncombatant) is an important predictor of later mental health problems, including posttraumatic stress disorder (PTSD). The present study aimed to update these findings by exploring the impact of type of killing on PTSD symptoms using a sample of postdeployment active duty U.S. Army personnel (N = 875). Using multiple regression analysis, we found that the act of killing a noncombatant was significantly associated with PTSD symptoms, B = 7.50, p < .001, whereas killing a combatant was not, B = -0.85, p = .360. This remained significant after controlling for demographic variables, depressive symptoms, and general combat experiences. These findings support the need for thoughtful postdeployment screenings and targeted clinical interventions.

To Trust is to Survive: Toward a Developmental Model of Moral Injury

Research on trauma- and stressor-related disorders has recently expanded to consider moral injury, or the harmful psychological impact of profound moral transgressions, betrayals, and acts of perpetration. Largely studied among military populations, this construct has rarely been empirically extended to children and adolescents despite its relevance in the early years, as well as youths' potentially heightened susceptibility to moral injury due to ongoing moral development and limited social resources relative to adults. Application of the construct to young persons, however, requires theoretical reconceptualization from a developmental perspective. The present paper brings together theory and research on developmentally-oriented constructs involving morally injurious events, including attachment trauma, betrayal trauma, and perpetration-induced traumatic stress, and describes how they may be integrated and extended to inform a developmentally-informed model of moral injury. Features of such a model include identification of potentially morally injurious events, maladaptive developmental meaning-making processes that underlie moral injury, as well as behavioral and emotional indicators of moral injury among youth. Thus, this review summarizes the currently available developmental literatures, identifies the major implications of each to a developmentally-informed construct of moral injury, and presents a conceptual developmental model of moral injury for children and adolescents to guide future empirical research.

The role of violence perpetration in driving externalizing problems and offending behavior among youth from eastern Democratic Republic of Congo

Youth in conflict-affected regions are exposed to a multitude of traumatic events. These individuals often witness violence; experience it firsthand; and, in some cases, become perpetrators. The interplay of events shapes systematic trauma histories that may have unique implications for youths' mental health. In a cross-sectional study conducted in eastern Democratic Republic of Congo (DRC), we interviewed 295 war-affected youth (63.4% boys, M_age = 16.70 years), including former child soldiers (n = 171), regarding their traumatic experiences and mental health. Using latent class analysis, we identified four common trauma history classes categorized by (a) low exposure, (b) medium exposure, (c) high exposure, and (d) high exposure/perpetration. Across the sample, gradual increases in trauma load corresponded with increased vulnerability to posttraumatic stress disorder (PTSD) symptoms, η_p ² = .36, and internalizing problems, η_p ² = .12; however, only youth from the high exposure/perpetration class differed significantly from other youth in their levels of externalizing problems, η_p ² = .13, and offending behaviors, η_p ² = .17. A longer time in armed groups was related to a higher risk of both experiencing and perpetrating violence. The results indicate that it is not child soldier status, per se, but the perpetration of violence that reinforces a cycle of violence in conflict-affected societies by contributing to increased externalizing problems and offending behaviors. In conflict regions, integrated approaches are needed to address both trauma and externalizing problems of war-affected youth.

Mindfulness to Manage Moral Injury: Rationale and development of a live online 7-week group intervention for veterans with moral injury

Background

Military service puts service members at risk for moral injury. Moral injury is an array of symptoms (e.g., guilt, shame, anger) that develop from events that violate or transgress one's moral code.

Objective

We describe adaption of in-person mindfulness training program, Mindfulness to Manage Chronic Pain (MMCP), to address symptoms of moral injury to be delivered live via the web. We discuss how we will assess benchmarks (i.e., recruitment, credibility and acceptability, completion rates, and adherence) of the Mindfulness to Manage Moral Injury (MMMI) program.

Methods

Aim 1: To develop and then adapt the MMCP program based on feedback from experts and veterans who took part in Study 1. Aim 2: To develop an equally intensive facilitator-led online Educational Support (ES) program to serve as a comparison intervention and conduct a run-through of each program with 20 veterans (10 MMMI; 10 ES). Aim 3: To conduct a small-scale randomized controlled trial (N = 42 veterans; 21 MMMI; 21 ES) in which we will collect pre-post-test and weekly benchmark data for both refined intervention arms.

Results

Study 1 and 2 are completed. Data collection for Study 3 will be completed in 2022.

Conclusion

MMMI is designed to provide a live facilitated mindfulness program to address symptoms of moral injury. If Study 3 demonstrates good benchmarks, with additional large-scale testing, MMMI may be a promising treatment that can reach veterans who may not seek traditional VAMC care and/or who prefer a web-based program.

Trajectories of functioning in a population-based sample of veterans: contributions of moral injury, PTSD, and depression

BACKGROUND

Although research has shown that exposure to potentially traumatic and morally injurious events is associated with psychological symptoms among veterans, knowledge regarding functioning impacts remains limited.

METHODS

A population-based sample of post-9/11 veterans completed measures of intimate relationship, health, and work functioning at approximately 9, 15, 21, and 27 months after leaving service. Moral injury, posttraumatic stress, and depression were assessed at ~9 months post-separation. We used Latent Growth Mixture Models to identify discrete classes characterized by unique trajectories of change in functioning over time and to examine predictors of class membership.

RESULTS

Veterans were assigned to one of four functioning trajectories: high and stable, high and decreasing, moderate and increasing, and moderate and stable. Whereas posttraumatic stress, depression, and moral injury associated with perpetration and betrayal predicted worse outcomes at baseline across multiple functioning domains, moral injury associated with perpetration and depression most reliably predicted assignment to trajectories characterized by relatively poor or declining functioning.

CONCLUSIONS

Moral injury contributes to functional problems beyond what is explained by posttraumatic stress and depression, and moral injury due to perpetration and depression most reliably predicted assignment to trajectories characterized by functional impairment over time.

Moral Injury and Recovery in Uniformed Professionals: Lessons From Conversations Among International Students and Experts

Introduction

In the course of service, military members, leaders, and uniformed professionals are at risk of exposure to potentially morally injurious events (PMIEs). Serious mental health consequences including Moral Injury (MI) and Post-traumatic stress disorder (PTSD) can result. Guilt, shame, spiritual/existential conflict, and loss of trust are described as core symptoms of MI. These can overlap with anxiety, anger, re-experiencing, self-harm, and social problems commonly seen in PTSD. The experiences of General (retired) Romeo Dallaire and other international experts who have led in times of crisis can help us better understand MI and recovery.

Objectives

In honor of Dallaire, online opportunities were created for international students and leaders/experts to discuss topics of MI, stigma, and moral codes in times of adversity as well as the moral impact of war. We aimed to (1) better understand MI and moral dilemmas, and (2) identify key insights that could inform prevention of and recovery from MI.

Materials and Methods

Webinars and conversations of 75-90 min duration on MI and recovery were facilitated by Leiden University, the University of Alberta and the Dallaire Institute for Children, Peace and Security between General Dallaire, world experts, and graduate students. Sessions were recorded, transcribed and thematically analyzed with NVivo using standard qualitative methodology.

Results

Ninety four participants engaged in conversations. Student engagements were attended by participants [N = 51; female (29), male (22)] from the Netherlands and Canada. Conversations were held with international experts [N = 43; female (19) and male (24)] from North America, Europe, Australia and the global south. Themes included: (1) recognizing the impact of exposure to PMIEs, (2) reducing stigma around MI, and (3) embracing the spiritual depth of humanity.

Conclusion

Exposure to PMIEs can have devastating impacts on military members, leaders and other uniformed professionals. This may lead to development of MI and PTSD. Recognizing MI as honorable may reduce stigma and psychological harm, and facilitate help-seeking among uniformed personnel and other trauma-affected populations. Salient efforts to address MI must include use of accurate measurements of MI and integrated holistic therapeutic approaches, inclusive of spiritual and social components. Urgency remains regarding the prediction, identification and treatment of MI.

Treatment for Moral Injury: Impact of Killing in War

Purpose of Review

Veterans who kill in war are at risk of developing negative mental health problems including moral injury, PTSD, spiritual distress, and impairments in functioning. Impact of Killing (IOK) is a novel, cognitive-behaviorally based treatment designed to address the symptoms associated with killing that focuses on self-forgiveness and moral repair through cultivation of self-compassion and perspective-taking exercises, such as letter writing, and active participation in values-driven behavior.

Recent Findings

In a pilot trial assessing IOK, participants demonstrated a reduction in multiple mental health symptoms and improvement in quality-of-life measures, and they reported IOK was acceptable and feasible. Furthermore, trauma therapists have reported that moral injury is relevant to their clinical work, expressed a desire for additional training on the impact of killing, and identified barriers that make addressing killing in clinical settings challenging. Data are currently being collected in a national multi-site trial to examine the efficacy of IOK, compared to a control condition.

Summary

IOK fills a critical treatment gap by directly addressing the guilt, shame, self-sabotaging behaviors, functional difficulties, impaired self-forgiveness, and moral/spiritual distress directly associated with killing in war. Typically provided following some initial trauma-processing treatment, IOK can be integrated in existing systems of trauma care, creating a pathway for a stepped model of treatment for moral injury.

The mental health of Vietnam theater veterans-the lasting effects of the war: 2016-2017 Vietnam Era Health Retrospective Observational Study

Mental health data from the 2016-2017 Vietnam Era Health Retrospective Observational Study (VE-HEROeS) were analyzed by cohort, represented by United States Vietnam theater veterans (VTs) who served in Vietnam, Cambodia, and Laos; nontheater veterans (NTs) without theater service; and age- and sex-matched nonveterans (NVs) without military service. The exposure of interest was Vietnam theater service. Surveys mailed to random samples of veterans (n = 42,393) and nonveterans (n = 6,885) resulted in response rates of 45.0% for veterans (n = 6,735 VTs, M_age = 70.09, SE = 0.04; n = 12,131 NTs) and 67.0% for NVs (n = 4,530). We examined self-report data on four mental health outcomes: probable posttraumatic stress disorder (PTSD), depression, psychological distress, and overall mental health functioning. Weighted adjusted odds ratios (aORs) between each outcome and cohort were estimated, controlling for covariates in four models: cohort plus sociodemographic variables (Model 1), Model 1 plus physical health variables (Model 2), Model 2 plus potentially traumatic events (PTEs; Model 3), and Model 3 plus other military service variables (Model 4). Mental health outcome prevalence was highest for VTs versus other cohorts, with the largest aOR, 2.88, for PTSD, 95% CI [2.46, 3.37], p < .001 (Model 4, VT:NT). Physical health and PTEs contributed most to observed effects; other service variables contributed least to aORs overall. Mental health dysfunction persists among VTs years after the war's end. The present results reaffirm previous findings and highlight the need for continued mental health surveillance in VTs.

To shoot or not to shoot: experiments on moral injury in the context of West Bank checkpoints and COVID-19 restrictions enforcement

BACKGROUND

Does exposure to events that transgress accepted norms, such as killing innocent civilians, prompt the psychological and emotional consequences of moral injury among soldiers? Moral injury is associated with negative emotions such as guilt, shame and anger, and a sense of betrayal and is identified among veterans following exposure to potentially morally injurious events (PMIE).

OBJECTIVE

We experimentally investigate how PMIE characteristics affect the intensity of MI and related negative moral emotions in participants with varied military experience.

METHOD

We conducted three controlled, randomized experiments. Each exposed male respondents with active combat experience (Study 1) and varied military experience (Study 2) to four textual vignettes describing PMIE (child/adult and innocent/non-innocent suspect) that transpire at an Israeli checkpoint in the West Bank. In study 3, we exposed participants to two scenarios, where descriptions of police officers enforcing COVID 19 restrictions confronted lockdown violators.

RESULTS

Participants assigned to vignettes describing killing an innocent civilian exhibited more intense levels of shame and guilt than those assigned to vignettes describing killing a person carrying a bomb. Religiosity and political ideology were strong predictors of guilt and shame in response to descriptions of checkpoint shootings. These effects disappeared in Study 3, suggesting that political ideology drives MI in intergroup conflict.

CONCLUSIONS

Background and PMIE-related characteristics affect the development of moral injury. Additionally, lab experiments demonstrate the potential and limitations of controlled studies of moral injury and facilitate an understanding of the aetiology of moral injury in a way unavailable to clinicians. Finally, experimental findings and methodologies offer further insights into the genesis of moral injury and avenues for therapy and prophylaxis.

Association Between Responsibility for the Death of Others and Postdeployment Mental Health and Functioning in US Soldiers

IMPORTANCE

Rates of suicidal thoughts and behaviors (STBs) in US soldiers have increased sharply since the terrorist attacks on September 11, 2001, and postdeployment posttraumatic stress disorder (PTSD) remains a concern. Studies show that soldiers with greater combat exposure are at an increased risk for adverse mental health outcomes, but little research has been conducted on the specific exposure of responsibility for the death of others.

OBJECTIVE

To examine the association between responsibility for the death of others in combat and mental health outcomes among active-duty US Army personnel at 2 to 3 months and 8 to 9 months postdeployment.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study obtained data from a prospective 4-wave survey study of 3 US Army brigade combat teams that deployed to Afghanistan in 2012. The sample was restricted to soldiers with data at all 4 waves (1-2 months predeployment, and 2-3 weeks, 2-3 months, and 8-9 months postdeployment). Data analysis was performed from December 12, 2020, to April 23, 2021.

MAIN OUTCOMES AND MEASURES

Primary outcomes were past-30-day PTSD, major depressive episode, STBs, and functional impairment at 2 to 3 vs 8 to 9 months postdeployment. Combat exposures were assessed using a combat stress scale. The association of responsibility for the death of others during combat was tested using separate multivariable logistic regression models per outcome adjusted for age, sex, race and ethnicity, marital status, brigade combat team, predeployment lifetime internalizing and externalizing disorders, and combat stress severity.

RESULTS

A total of 4645 US soldiers (mean [SD] age, 26.27 [6.07] years; 4358 men [94.0%]) were included in this study. After returning from Afghanistan, 22.8% of soldiers (n = 1057) reported responsibility for the death of others in combat. This responsibility was not associated with any outcome at 2 to 3 months postdeployment (PTSD odds ratio [OR]: 1.23 [95% CI, 0.93-1.63]; P = .14; STB OR: 1.19 [95% CI, 0.84-1.68]; P = .33; major depressive episode OR: 1.03 [95% CI, 0.73-1.45]; P = .87; and functional impairment OR: 1.12 [95% CI, 0.94-1.34]; P = .19). However, responsibility was associated with increased risk for PTSD (OR, 1.42; 95% CI, 1.09-1.86; P = .01) and STBs (OR, 1.55; 95% CI, 1.03-2.33; P = .04) at 8 to 9 months postdeployment. Responsibility was not associated with major depressive episode (OR, 1.30; 95% CI, 0.93-1.81; P = .13) or functional impairment (OR, 1.13; 95% CI, 0.94-1.36; P = .19). When examining enemy combatant death only, the pattern of results was unchanged for PTSD (OR, 1.44; 95 CI%, 1.10-1.90; P = .009) and attenuated for STBs (OR, 1.46; 95 CI%, 0.97- 2.20; P = .07).

CONCLUSIONS AND RELEVANCE

This cohort study found an association between being responsible for the death of others in combat and PTSD and STB at 8 to 9 months, but not 2 to 3 months, postdeployment in active-duty soldiers. The results suggest that delivering early intervention to those who report such responsibility may mitigate the subsequent occurrence of PTSD and STBs.

Moral Injury Among Nigerian Soldiers Following Combat: Case Reports and a Review of the Literature

Moral injury is a phenomenon in which unpleasant psychological consequences such as guilt and shame follow exposure to activities that transgress one's deeply held moral beliefs and expectations. Combat engagement places service members at a heightened risk on account of exposure to potentially morally injurious experiences (PMIEs). It remains a more recent construct in comparison with posttraumatic stress disorder (PTSD) despite several studies. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) effectively subsumed moral injury as a part of PTSD, recognizing moral injury as symptoms rather than events that are followed by specific symptoms. Nothing has been reported on moral injury, its prevalence, and associated factors among Nigerian soldiers despite exposure to PMIE in combat and abundance of literature worldwide. Unlike PTSD, moral injury is often under-recognized by clinicians and military and nonmilitary health personnel, and particularly, in our setting where nonmilitary mental health personnel sometimes have to treat postcombat military patients. Failure of recognition of moral injury (and not addressing it) can adversely affect overall mental health and may increase the risk of suicide. We report three cases of personnel of the Nigerian Army referred to our clinic after combat in northeastern Nigeria and following exposure to PMIE, the circumstances of exposure to morally injurious situations and subsequent reactions. Our study brought up several findings including the effect of exposure to multiple potentially injurious events, apparent frequent co-occurrence of moral injury with PTSD, and the complicating unpleasant mental health outcomes. Being a report of cases, this implies that generalizations might not be warranted but serve as possible questions for future research.

Patterns of distress associated with exposure to potentially morally injurious events among Canadian Armed Forces service members and Veterans: A multi-method analysis

OBJECTIVE

This study describes patterns of distress associated with exposure to potentially morally injurious experiences (PMIEs) in a Canadian military sample.

METHOD

Thematic analysis was performed on interviews from PMIE-exposed military members and Veterans. Participants also completed structured diagnostic interviews, and measures of trauma exposure and psychopathology. Multiple regression examined associations among these variables. Information on pharmacological treatment and past diagnoses are reported.

RESULTS

Eight qualitative themes were identified: changes in moral attitudes, increased sensitivity and reactivity to moral situations, loss of trust, disruptions in identity, disruptions in spirituality, disruptions in interpersonal relatedness, rumination, and internalizing and externalizing emotions and behaviors. Self-report data revealed that degree of PMIE exposure was meaningfully associated with posttraumatic stress disorder.

CONCLUSION

Qualitative but not quantitative findings supported existing models of moral injury (MI). Additional research is needed to examine the impact of PMIE type on mental health, and to test basic assumptions of MI theory.

Combat stress in a small-scale society suggests divergent evolutionary roots for posttraumatic stress disorder symptoms

Did PTSD and combat stress evolve as a universal human response to danger? Or are they culturally specific? We addressed this question by interviewing 218 warriors from the Turkana, a non-Western small-scale society, who engage in high-risk lethal cattle raids. We found that symptoms that may have evolved to protect against danger, like flashbacks and startle response, were high in the Turkana and best predicted by combat exposure. However, symptoms that are similar to depression were lower in the Turkana compared to American service members and were better predicted by moral violations. These findings suggest different evolutionary roots for different symptoms which may lead to better diagnosis and treatment.

Military personnel in industrialized societies often develop posttraumatic stress disorder (PTSD) during combat. It is unclear whether combat-related PTSD is a universal evolutionary response to danger or a culture-specific syndrome of industrialized societies. We interviewed 218 Turkana pastoralist warriors in Kenya, who engage in lethal cattle raids, about their combat experiences and PTSD symptoms. Turkana in our sample had a high prevalence of PTSD symptoms, but Turkana with high symptom severity had lower prevalence of depression-like symptoms than American service members with high symptom severity. Symptoms that facilitate responding to danger were better predicted by combat exposure, whereas depressive symptoms were better predicted by exposure to combat-related moral violations. The findings suggest that some PTSD symptoms stem from an evolved response to danger, while depressive PTSD symptoms may be caused by culturally specific moral norm violations.

Distinguishing the Effects of Life Threat, Killing Enemy Combatants, and Unjust War Events in U.S. Service Members

Although previous studies have identified behavioral health risks associated with combat exposure, it is unclear which types of combat events are associated with these risks, particularly regarding contrasts among the risks associated with life-threatening experiences, killing combatants, and exposure to unjust war events, such as killing a noncombatant or being unable to help civilian women and children. In the present study, we examined surveys from 402 soldiers following deployment (i.e., baseline) and again 13 months later (i.e., Year 1). Regression analyses were conducted across a range of behavioral health (e.g., posttraumatic stress disorder, depression, suicide ideation, anxiety, somatic, insomnia, aggression) and benefit-finding measures, each controlling for two combat event categories while assessing the predictive utility of a third. The results suggested that life-threatening events were associated with poor behavioral health at baseline, relative risk (RR) = 10.00, but not at Year 1, RR = 2.67. At both baseline and Year 1, killing enemy combatants was not associated with behavioral health, RRs = 1.67-3.33, but was positively associated with benefit-finding, RRs = 26.67-40.00. Exposure to unjust war events was associated with a transdiagnostic pattern of behavioral health symptoms at baseline, RR = 40.00, and Year 1, RR = 23.33. Overall, the results suggest unjust war event exposure is particularly injurious, above and beyond exposure to other combat-related events. Future research can build on these findings to develop clearer descriptions of the combat events that might place service members at risk for moral injury and inform the development of assessment and treatment options.

Gender differences in prevalence and outcomes of exposure to potentially morally injurious events among post-9/11 veterans

Our goal was to identify gender differences in the prevalence and outcomes of exposure to potentially morally injurious events (PMIEs) in a sample of U.S. military veterans. In a national sample of post-9/11 veterans (n = 7200) weighted to reflect the larger population of newly separated U.S. veterans, we conducted gender-stratified analyses of the prevalence of exposure to PMIEs and their associations with psychological and functional problems. Veterans reported exposures stemming from witnessing (27.9%), perpetrating (18.8%), and being betrayed (41.1%). Women more frequently reported witnessing- and betrayal-based PMIEs, but no gender differences were observed for perpetration-based PMIEs. Psychological distress was associated with witnessing and betrayal among women and with witnessing, betrayal, and perpetration among men. Whereas betrayal was most consistently associated with functional impairment across domains for women, perpetration was most consistently associated with functional impairment for men. Moral injury contributes to psychological and functional problems among a significant minority of military veterans, although effects vary based on PMIE type and gender. Implications for veterans and other populations who experience moral injury are discussed.

Psychospiritual Developmental Risk Factors for Moral Injury

There is increasing theoretical, clinical, and empirical support for the hypothesis that psychospiritual development, and more specifically, postconventional religious reasoning, may be related to moral injury. In this study, we assessed the contributions of exposure to potentially morally injurious events, posttraumatic stress symptoms, and psychospiritual development to moral injury symptoms in a sample of military veterans (N = 212). Psychospiritual development was measured as four dimensions, based on Wulff’s theory juxtaposing conventional vs. postconventional levels of religious reasoning, with decisions to be an adherent or a disaffiliate of faith. After controlling for exposure to potentially morally injurious events and severity of posttraumatic stress symptoms, veterans who were conventional disaffiliates reported higher scores on the Moral Injury Questionnaire than conventional adherents, postconventional adherents, or postconventional disaffiliates. We conclude that the role of psychospiritual development offers a theoretical approach to moral injury that invites collaboration between social scientists, philosophers, theologians, and medical professionals.

Mental disorders and medical conditions associated with causing injury or death: A population-based study

The aim of the present study is to examine mental disorders and medical conditions associated with causing harm to another person in the general adult population. The sample (n=22,138) was drawn from a cross-sectional survey designed to characterize mental health needs in France. Twelve-month DSM-IV axis I mental disorders and medical conditions, and lifetime occurrence of potentially traumatic events were assessed with the Composite International Diagnostic Interview-SF Overall, 2% (n=430) of the sample reported having injured or killed someone. Causing harm was associated with male gender, lower education level, and being unemployed. The great majority (85%) of those who caused harm had experienced two or more additional potentially traumatic events. When adjusting for gender, employment status, education and number of events experienced, causing harm was associated with certain anxiety disorders, drug dependence and lifetime suicide attempt but not with major depression or post-traumatic stress disorder. Furthermore, causing harm was not associated with medical conditions in multivariate analyses. These results highlight the need for clinicians to be particularly attentive to the psychological burden that may be experienced by those who have harmed or killed someone.

Moral Injury: An Integrative Review

Individuals who are exposed to traumatic events that violate their moral values may experience severe distress and functional impairments known as "moral injuries." Over the last decade, moral injury has captured the attention of mental health care providers, spiritual and faith communities, media outlets, and the general public. Research about moral injury, especially among military personnel and veterans, has also proliferated. For this article, we reviewed scientific research about moral injury. We identified 116 relevant epidemiological and clinical studies. Epidemiological studies described a wide range of biological, psychological/behavioral, social, and religious/spiritual sequelae associated with exposure to potentially morally injurious events. Although a dearth of empirical clinical literature exists, some authors debated how moral injury might and might not respond to evidence-based treatments for posttraumatic stress disorder (PTSD) whereas others identified new treatment models to directly address moral repair. Limitations of the literature included variable definitions of potentially morally injurious events, the absence of a consensus definition and gold-standard measure of moral injury as an outcome, scant study of moral injury outside of military-related contexts, and clinical investigations limited by small sample sizes and unclear mechanisms of therapeutic effect. We conclude our review by summarizing lessons from the literature and offering recommendations for future research.

Introduction to the Special Issue on Moral Injury: Conceptual Challenges, Methodological Issues, and Clinical Applications

This article introduces a special issue of the Journal of Traumatic Stress devoted to new directions in the study of moral injury (MI), defined as transgressive harms and the outcomes of those experiences. Although a significant body of research has emerged devoted to the study of the MI construct, a number of conceptual and empirical challenges have arisen; these are summarized and discussed in the present article. In addition, this article proposes ways of overcoming these challenges in order to further research and clinical practice in the field. We then go on to introduce the content and themes of the present collection of articles in this special issue, all of which provide examples of some of the most innovative and forward-looking work on the topic and expand into new conceptual frameworks, new methods of investigation, and new populations and contexts.

Provider perspectives on a novel moral injury treatment for veterans: Initial assessment of acceptability and feasibility of the Impact of Killing treatment materials

OBJECTIVE

We assessed whether treatment providers specializing in evidence-based treatment for posttraumatic stress disorder found the Impact of Killing (IOK), a novel treatment for moral injury among combat veterans, acceptable, and feasible.

METHODS

Ten providers from a large veterans administration (VA) medical center were provided with materials from IOK. We audio-recorded a semistructured interview with each provider where we elicited open-ended feedback as well as asked five structured questions about the relative advantage, compatibility, complexity/simplicity, trialability, and observability of IOK.

RESULTS

All providers found IOK feasible, acceptable, and something they could incorporate into their existing practice. Providers reported that the spiritual and moral concerns addressed in IOK were novel, and that self-forgiveness and making amends were critical components promoting healing from moral injury not emphasized in other treatments.

CONCLUSIONS

Among trauma providers, IOK was found acceptable and feasible, offering a novel approach to addressing moral injury among combat veterans.

Sources of moral injury among war veterans: A qualitative evaluation

OBJECTIVE

Service members deployed to war are at risk for moral injury, but the potential sources of moral injury are poorly understood. The aim of this qualitative study was to explore the types of events that veterans perceive as morally injurious and to use those events to develop a categorization scheme for combat-related morally injurious events.

METHOD

Six focus groups with US war veterans were conducted.

RESULTS

Analysis based on Grounded Theory yielded two categories (and eight subcategories) of events that putatively cause moral injury. The two categories were defined by the focal attribution of responsibility for the event: Personal Responsibility (veteran's reported distress is related to his own behavior) versus Responsibility of Others (veteran's distress is related to actions taken by others). Examples of each type of morally injurious event are provided.

CONCLUSIONS

Implications for the further development of the moral injury construct and treatment are discussed.

Killing during combat and negative mental health and substance use outcomes among recent-era veterans: The mediating effects of rumination

OBJECTIVE

Although killing in combat is associated with negative mental health outcomes and hazardous alcohol use, mechanisms that underlie this risk are not well understood. To our knowledge, this present brief report is the first to use mediation analysis to examine associations between killing in combat, distinct facets of rumination (problem-focused thoughts, counterfactual thinking, repetitive thoughts, and anticipatory thoughts), and negative mental health outcomes (i.e., depression, anxiety, PTSD, suicidality) and hazardous alcohol use.

METHOD

Participants were a community sample of 283 military personnel (158 males [60.31%]; mean age = 32.61 [SD = 7.11]) who had deployed in support of recent wars in Iraq or Afghanistan. Participants completed an online self-report survey.

RESULTS

Three rumination facets (i.e., problem-focused thoughts, counterfactual thinking, and anticipatory thoughts) uniquely (controlling for effects of other rumination facets) mediated the associations between killing in combat and negative mental health outcomes and hazardous alcohol use. Taken together, killing in combat was associated with higher levels of each rumination facet, which in turn were distinctly associated with more negative symptoms of mental health and more hazardous drinking (problem-focused thoughts were the only facet to mediate all effects). Beyond these significant mediation effects, killing in combat still had a significant direct effect on every outcome.

CONCLUSION

These findings provide preliminary support for associations between killing in combat and negative mental health outcomes and hazardous alcohol use. Furthermore, rumination (particularly problem-focused thoughts) may be an important consideration in the evaluation and care of recent-era combat veterans.

Influence of military sexual assault and other military stressors on substance use disorder and PTS symptomology in female military veterans

Servicewomen exposed to traumatic stressors over the course of their military service are at increased risk of developing symptoms of substance use disorder (SUD) and posttraumatic stress (PTS). They are also at risk for exposure to military sexual assault (MSA), which is also associated with SUD and PTS symptomology. Research is unclear about the incremental contributions of different forms of traumatic stressors on co-occurring SUD and PTS symptomology. In this study we examined the independent and combined effects of MSA and other military stressors on SUD and PTS symptomology in a sample of female veterans (N=407). Results indicate that MSA and other military stressors exhibit incremental effects on SUD and PTS symptomology. Results further suggest that women exposed to both MSA and other military stressors are at increased risk for developing co-occurring SUD and PTSD. These findings extend previous research on comorbid SUD and PTSD, highlighting the cumulative effects of traumatic stressors on posttraumatic psychopathology, and have implications for future research and clinical practice with female veterans.

Psychopathology of children of genocide survivors: a systematic review on the impact of genocide on their children`s psychopathology from five countries

Background

: The health consequences of genocides on children of survivors are increasingly discussed but conclusions have been conflicting.

Methods

We systematically reviewed studies from five electronic databases (EMBASE, PILOTS, PUBMED, PsycINFO, Web of Science), which used a quantitative study design and included: (i) exposure to the genocides of Armenians in Nazi Germany, Cambodia, Rwanda and Bosnia; (ii) mental health outcomes; (iii) validated instruments; (iv) statistical tests of associations. Study quality was appraised using a quality assessment tool for genocide studies. PRISMA reporting guidelines were followed.

Results

From 3352 retrieved records, 20 studies with a total of 4793 participants involving 2431 children of survivors and 2362 controls met the eligibility criteria. Studies were conducted in seven countries: Australia, Canada, Italy, Israel, Norway, Rwanda and the USAs over the past seven decades, using the Genocide Studies Quality Assessment Tool. Data from the high quality studies provide no consistent evidence that children of genocide survivors are more likely to have mental health problems than comparators who were not children of genocide survivors.

Conclusions

Methodological characteristics were associated with findings: studies investigating random samples of genocide survivors did not find an impact of genocides on health of children of survivors. Potential confounders (e.g. recent life events, poverty) need further investigation. Future studies of the impact of genocides on mental health should report using a standardized structure, such as the quality tool used here.

Combat Experiences and their Relationship to Post-Traumatic Stress Disorder Symptom Clusters in UK Military Personnel Deployed to Afghanistan

The association of post-traumatic stress disorder (PTSD) symptom clusters with combat and other operational experiences among United Kingdom Armed Forces (UK AF) personnel who deployed to Afghanistan in 2009 were examined. Previous studies suggest that the risk of developing PTSD rises as combat exposure levels increase. To date, no UK research has investigated how specific classes of combat and operational experiences relate to PTSD symptom clusters. The current study was a secondary analysis of data derived from a two-arm cluster, randomized-controlled trial of a postdeployment operational stress-reduction intervention in deployed UK AF personnel. 2510 UK AF personnel provided combat exposure data and completed the PTSD checklist (civilian version) immediately post-deployment while 1635 of the original cohort completed further followed-up measures four to six months later. A 14-item combat experience scale was explored using principle component analysis, which yielded three main categories of experience: (1) violent combat, (2) proximity to wounding or death and (3) encountering explosive devices. The association of combat experience classes to PTSD 5-factor "dysphoric arousal" model (re-experiencing, avoidance, numbing, dysphoric-arousal and anxious-arousal symptoms) was assessed. Greater exposure to violent combat was predictive of re-experiencing and numbing symptoms, while proximity to wounding or death experiences were predictive of re-experiencing and anxious-arousal symptoms. Explosive device exposure was predictive of anxious-arousal symptoms. The present study suggests that categories of combat experience differentially impact on PTSD symptom clusters and may have relevance for clinicians treating military personnel following deployment.

Moral injury process and its psychological consequences among Israeli combat veterans

OBJECTIVES

We aim to examine the link between exposure to potentially morally injurious events (PMIEs) and posttraumatic stress disorder symptoms (PTSS). We also aim to explore the mediating roles of depressive attributions, trauma-related guilt and shame, and self-disgust in the relationship between PMIEs and PTSS among combat veterans.

METHOD

A volunteers' sample of 191 Israeli combat veterans responded to self-report questionnaires in a cross-sectional design study.

RESULTS

More than one-fifth of the sample reported experiencing PMIEs but only betrayal based experience was related to PTSS. Importantly, betrayal based experience was associated with depressive attributions which increased the level of trauma-related distressing guilt, intrinsic shame and self-disgust, which in turn were associated with high levels of PTSS.

CONCLUSIONS

PMIEs, and especially betrayal based experiences, are related to PTSS among Israeli veterans. Depressive attributions, trauma-related distressing guilt, intrinsic shame, and self-disgust might serve as possible mechanisms for the links between PMIEs and PTSS.

"Opening a Door to a New Life": The Role of Forgiveness in Healing From Moral Injury

For military veterans struggling with moral injury, forgiveness can become both an animating concern and a potential path to healing. In this perspective piece, we draw on our clinical work and research findings to examine why forgiveness matters to veterans who feel guilt and shame about their actions in war, what type of forgiveness is attainable and meaningful, and what role clinicians can play in facilitating forgiveness. We conclude by reflecting on the potential, as well as the limits and tensions, of forgiveness work in the context of military moral injury.

A Comparison of Veterans Who Repeat Versus Who Do Not Repeat a Course of Manualized, Cognitive-Behavioral Therapy for Posttraumatic Stress Disorder

Despite evidence that cognitive-behavioral therapy (CBT) for posttraumatic stress disorder (PTSD) is effective, some individuals do not experience clinically significant reduction or remission of their PTSD symptoms. These individuals may return for additional PTSD-focused psychotherapy. However, there is no research to know whether PTSD treatment repeaters have worse symptoms prior to the initial treatment episode or display differences in other pretreatment characteristics versus nonrepeaters. Research is also needed to explore whether treatment repeaters exhibit PTSD symptom changes during an initial or second course of treatment. The current study examines differences in pretreatment characteristics and treatment response among U.S. military veterans who participated in either a single course (n = 711) or in two separate courses (n = 87) of CBT for PTSD through an outpatient Veterans Affairs PTSD treatment program. Veterans completing two courses of CBT for PTSD were more likely to be married and employed and more likely to drop out of their initial course of treatment versus those who completed a single course. Hierarchical linear models showed that reductions in PTSD symptoms during treatment were not different for those who completed a second versus single course of CBT for PTSD. However, for those participating in two courses of CBT for PTSD, a relapse in PTSD symptoms was observed between the first and second course. These findings show that a second course of CBT may be viable for those with ongoing PTSD symptoms.

Understanding the Impact and Treatment of Moral Injury Among Military Service Members

Moral injury refers to a set of reactions to acts of perpetration or commission that violate an individual's deeply held beliefs and moral values. Although there is consensus that military service increases exposure to morally injurious events, there is no clear definition on what events do and do not constitute moral injury, which makes drawing firm conclusions regarding the prevalence of moral injury among military populations difficult. Exposure to morally injurious events places individuals at a greater risk for a range of poor mental health outcomes, which may be mediated by negative posttraumatic cognitions. Therefore, treatments that emphasize restructuring such cognitions are likely to be effective in treating the effects of moral injury, though data are lacking. In this article, we provide an overview of the key scientific findings regarding moral injury and highlight areas where future research is needed. Potential challenges in treating the negative sequelae of moral injury are also discussed.

Physical and Mental Health Consequences of War-related Stressors Among Older Adults: An Analysis of Posttraumatic Stress Disorder and Arthritis in Northern Vietnamese War Survivors

Objectives

We examine the impacts of trauma exposures and family stressors associated with the Vietnam War on musculoskeletal health and posttraumatic stress disorder (PTSD) outcomes in elderly Vietnamese who were widely impacted by the war as young adults. Noting that wars' impacts extend beyond male veterans in most survivor populations, we give attention to male and female war survivors placed in a variety of roles vis-a-vis the war.

Method

Utilizing data from the 2010 Vietnam Health and Aging Pilot Study (N = 405), we use logistic and Poisson regression models to estimate the effect of wartime trauma exposures and family stressors on disabling arthritis and PTSD symptoms in male and female northern Vietnamese adults aged 55 and older.

Results

The odds of experiencing recent PTSD symptoms are greater in respondents who report involvement in killing/causing severe injury and who observed war atrocities. In women, PTSD is positively correlated with war era child death and spousal separation. Arthritis also exhibits a significant, positive association with killing/causing severe injury.

Discussion

Our study provides insights into the burden of conflict upon health among populations of the global south that survived war and are now entering older adulthood. The pattern of results, indicating greatest suffering among those who inflicted or failed to prevent bodily harm or loss of life, is consistent with the concept of moral injury.

Characteristics of veterans and military service members who endorse causing harm, injury, or death to others in the military

OBJECTIVE

The purpose of the present research was to examine the demographic and mental health characteristics of veterans and service members who endorsed having caused harm, injury, or death to another person on deployment, while taking these individuals' total number of other lifetime traumas into account.

METHOD

Data for the present study were collected as part of the standard clinical evaluation for 228 treatment-seeking veterans and service members.

RESULTS

Those who reported having caused harm, injury, or death to another person on deployment (22.4%) were more likely to be male, to have served in the Marines, to have served post 9/11, and to endorse other traumas commonly reported on deployment than those who did not endorse causing harm, injury, or death. Those who endorsed causing harm on deployment were less likely to have served in the Air Force, and to have experienced sexual assault than those who did not cause harm. Causing harm, injury, or death was associated with higher levels of posttraumatic stress disorder (PTSD), drug use, and expressive anger at the bivariate level, but was no longer associated with mental health problems after accounting for the number of other lifetime traumas.

CONCLUSIONS

Examining the role of causing harm in isolation may lead to false conclusions. Clinicians and researchers should assess for veterans' and service members' entire trauma histories. (PsycINFO Database Record

Predictors of PTSD 40 years after combat: Findings from the National Vietnam Veterans longitudinal study

BACKGROUND

Few studies have longitudinally examined predictors of posttraumatic stress disorder (PTSD) in a nationally representative sample of US veterans. We examined predictors of warzone-related PTSD over a 25-year span using data from the National Vietnam Veterans Longitudinal Study (NVVLS).

METHODS

The NVVLS is a follow-up study of Vietnam theater veterans (N = 699) previously assessed in the National Vietnam Veterans Readjustment Study (NVVRS), a large national-probability study conducted in the late 1980s. We examined the ability of 22 premilitary, warzone, and postmilitary variables to predict current warzone-related PTSD symptom severity and PTSD symptom change in male theater veterans participating in the NVVLS. Data included a self-report Health Questionnaire survey and a computer-assisted telephone Health Interview Survey. Primary outcomes were self-reported PTSD symptoms assessed by the PTSD Checklist for DSM-5 (PCL 5) and Mississippi PTSD Scale (M-PTSD).

RESULTS

Predictors of current PTSD symptoms most robust in hierarchical multivariable models were African-American race, lower education level, negative homecoming reception, lower current social support, and greater past-year stress. PTSD symptoms remained largely stable over time, and symptom exacerbation was predicted by African-American race, lower education level, younger age at entry into Vietnam, greater combat exposure, lower current social support, and greater past-year stressors.

CONCLUSIONS

Findings confirm the robustness of a select set of risk factors for warzone-related PTSD, establishing that these factors can predict PTSD symptom severity and symptom change up to 40 years postdeployment.

Moral injury in U.S. combat veterans: Results from the national health and resilience in veterans study

BACKGROUND

Combat exposure is associated with increased risk of mental disorders and suicidality. Moral injury, or persistent effects of perpetrating or witnessing acts that violate one's moral code, may contribute to mental health problems following military service. The pervasiveness of potentially morally injurious events (PMIEs) among U.S. combat veterans, and what factors are associated with PMIEs in this population remains unknown.

METHODS

Data were analyzed from the National Health and Resilience in Veterans Study (NHRVS), a contemporary and nationally representative survey of a population-based sample of U.S. veterans, including 564 combat veterans, collected September-October 2013. Types of PMIEs (transgressions by self, transgressions by others, and betrayal) were assessed using the Moral Injury Events Scale. Psychiatric and functional outcomes were assessed using established measures.

RESULTS

A total of 10.8% of combat veterans acknowledged transgressions by self, 25.5% endorsed transgressions by others, and 25.5% endorsed betrayal. PMIEs were moderately positively associated with combat severity (β = .23, P < .001) and negatively associated with white race, college education, and higher income (βs = .11-.16, Ps < .05). Transgressions by self were associated with current mental disorders (OR = 1.65, P < .001) and suicidal ideation (OR = 1.67, P < .001); betrayal was associated with postdeployment suicide attempts (OR = 1.99, P < .05), even after conservative adjustment for covariates, including combat severity.

CONCLUSIONS

A significant minority of U.S combat veterans report PMIEs related to their military service. PMIEs are associated with risk for mental disorders and suicidality, even after adjustment for sociodemographic variables, trauma and combat exposure histories, and past psychiatric disorders.

Veterans’ Perspectives on the Psychosocial Impact of Killing in War

Based on focus group and individual interviews with 26 combat veterans, this qualitative thematic analysis examines the psychosocial and interpersonal consequences of killing in war. It describes the consequences that veterans identify as most relevant in their lives, including postwar changes in emotions, cognitions, relationships, and identity. Furthermore, it illustrates the linked psychological and social dimensions of those consequences—namely, how the impact of killing in war is rooted in the unique perspectives, actions, and experiences of individual veterans, as well as the social worlds they confront upon returning from war. We found that, for many veterans, killing provokes a moral conflict with a lasting impact on their sense of self, spirituality, and relationships with others. In working with combat veterans, mental health professionals should be sensitive to the complexities of discussing killing and attuned to the psychosocial challenges veterans may face after taking a life in war.

Intimate partner aggression-related shame and posttraumatic stress disorder symptoms: The moderating role of substance use problems

A dearth of literature has examined the consequences of women's use of aggression in intimate relationships. Women's use of aggression against their intimate partners, regardless of their motivation (e.g., self-defense, retaliation), may elicit shame. Shame, in turn, may contribute to the maintenance and/or exacerbation of posttraumatic stress disorder (PTSD) symptoms, which are commonly experienced in this population. Further, emerging research suggests that emotionally avoidant coping strategies, such as substance use, may strengthen the relation between shame and PTSD symptoms. The goal of the present study was to examine whether women's shame concerning their use of intimate partner aggression is associated with their PTSD symptoms, and whether drug and alcohol use problems moderate this association. Participants were 369 community women who had used and been victimized by physical aggression in an intimate relationship with a male partner in the past six months. The intimate partner aggression-related shame × drug (but not alcohol) use problems interaction on PTSD symptom severity was significant. Analysis of simple slopes revealed that women's intimate partner aggression-related shame was positively associated with their PTSD symptoms when drug use problems were high, but not when drug use problems were low. Findings have implications for the potential utility of PTSD treatments targeting a reduction in shame and maladaptive shame regulation strategies (i.e., drug use) in this population. Aggr.

[Psychiatric, Cognitive and Emotional Profile in Ex-combatants of Illegal Armed Groups in Colombia]

INTRODUCTION

Exposure to armed conflict produces biological adaptations oriented to handle the highly stressful conditions in war environments. The special features of The Colombian armed create a special scenario to evaluate the human behavior.

OBJECTIVE

In this study, psychiatric, cognitive and emotional processing characteristics of a group of Colombian armed illegal forces of ex-combatants are described.

METHODS

Sixty-three ex combatants and 22 controls were assessed with WAIS (IQ), INECO frontal screening (executive functions), Interpersonal Reactivity Index (empathy), emotional features recognition and MINI (psychiatric profile).

RESULTS

When compared to the control group, ex-combatants showed higher frequency of antisocial personality disorder (P=.031) and behavioral dissocial disorder (P=.017). In cognitive profile, the ex-combatants showed a lower score in the executive function test (Me=18.50; RQ=4.00), control (Me=23.00; RQ=5.25), with a poor personal distress in emphatic profile (Me=10.00; RQ=5.00) compared to control group (Me=37.00; RQ=7.25).

CONCLUSIONS

We found differences in cognitive and psychiatric profile in ex-combatants in comparison with controls.

Violent Offending Promotes Appetitive Aggression Rather than Posttraumatic Stress-A Replication Study with Burundian Ex-Combatants

Research has identified appetitive aggression, i.e., the perception of committed, violent acts as appealing, exciting and fascinating, as a common phenomenon within populations living in precarious and violent circumstances. Investigating demobilized soldiers in the Democratic Republic of Congo (DRC) demonstrated that violent offending is associated with appetitive aggression and not necessarily with symptoms of posttraumatic stress. In the present study, we sought to replicate these results in an independent and larger sample of demobilized soldiers from Burundi. As with the Congolese ex-combatants, random forest regression revealed that the number of lifetime perpetrated violent acts is the most important predictor of appetitive aggression and the number of lifetime experienced traumatic events is the main predictor for posttraumatic stress. Perpetrated violent acts with salient cues of hunting (pursuing the victim, the sight of blood, etc.) were most predictive for perceiving violent cues appealingly after demobilization. Moreover, the association of violent acts and appetitive aggression as well as traumatic events and posttraumatic stress remains strong even years after demobilization. Patterns of traumatic events and perpetrated acts as predictors for posttraumatic stress and appetitive aggression seem to be robust among different samples of ex-combatants who fought in civil wars. Psychotherapeutic interventions that address these complementary facets of combat-related disorders—namely, posttraumatic stress and appetitive aggression—are indispensable for a successful reintegration of those who fought in armed conflicts and to achieve a successful transition to peace.

Combat high or traumatic stress: violent offending is associated with appetitive aggression but not with symptoms of traumatic stress

Former members of armed groups in eastern DR Congo had typically witnessed, experienced, and perpetrated extreme forms of violence. Enhanced trauma-related symptoms had been shown in prior research. But also lashing out in self-defense is a familiar response to threat defined as reactive aggression. Another potential response is appetitive aggression, in which the perpetration of excessive violence is perceived as pleasurable (combat high). What roles do these forms of aggressive behavior play in modern warfare and how are they related to posttraumatic stress symptoms? To answer the question, we sought to determine predictors for appetitive aggressive and trauma-related mental illness, and investigated the frequency of psychopathological symptoms for high- and low-intensity conflict demobilization settings. To this end, we interviewed 213 former members of (para)military groups in the eastern Democratic Republic of Congo in regard to their combat exposure, posttraumatic stress, appetitive aggression, depression, suicidality, and drug dependence. Random forest regression embedded in a conditional inference framework revealed that perpetrated violent acts are not necessarily stressful. In fact, the experience of violent acts that typically implicated salient cues of hunting (e.g., blood, suffering of the victim, etc.) had the strongest association with an appetite for aggression. Furthermore, the number of lifetime perpetrated violent acts was the most important predictor of appetitive aggression. However, the number of perpetrated violent acts did not significantly affect the posttraumatic stress. Greater intensity of conflict was associated with more severe posttraumatic stress symptoms and depression. Psychotherapeutic interventions that address appetitive aggression in addition to trauma-related mental illness, including drug dependence, therefore seem indispensible for a successful reintegration of those who fought in the current civil wars.
