The impact of reported direct and indirect killing on mental health symptoms in Iraq war veterans

Spirituality and Moral Injury Among Military Personnel: A Mini-Review

Introduction: Moral injury (MI) results when military personnel are exposed to morally injurious events that conflict with their values and beliefs. Given the complexity of MI and its physical, emotional, social, and spiritual impact, a holistic approach is needed. While the biopsychosocial aspects of MI are more commonly addressed, less is known of the spiritual dimension and how to incorporate it into treatment that facilitates restoration of one's core self and mending of relationships with self, others, and the sacred/Transcendent. The purpose of this study was to gain a greater understanding of the relationship between spirituality/religion (S/R) and MI as experienced by military members and veterans and to consider how S/R might be better integrated into prevention and treatment strategies. Methods: A mini-review of peer-reviewed articles published between January 2000 and April 2018 regarding the relationship between spirituality and MI among military personnel and veterans was conducted. Results: Twenty-five articles were included in the final review. Five themes were identified and explored, including i) Spirituality: A potential cause of and protective factor against MI, ii) Self and identity: Lost and found, iii) Meaning-making: What once was and now is, iv) Spirituality as a facilitator of treatment for MI, and v) Faith communities: Possible sources of fragmentation or healing. Discussion: Findings identified a cyclical relationship between S/R and MI, whereby S/R can both mitigate and exacerbate MI, as well as be affected by it. Seen as a type of S/R struggle, the use of S/R-specific strategies [e.g., forgiveness, review of S/R beliefs, engagement in S/R practices, and (re)connection with S/R communities], integration of S/R perspectives into general interventions, and help from chaplains may support healing, self-regulation, and mending of relationships, moral emotions, and social connection. Further research is yet needed, however, regarding i) S/R orienting systems, interventions, practices, and rituals/ceremonies that might protect against and treat MI; ii) features of individuals who do/do not experience MI; iii) S/R assessment tools and interventions; and iv) ways to maximize the positive contributions of faith communities.

Moral injury in UK armed forces veterans: a qualitative study

Background: Moral injury has been found to adversely affect US veteran mental health, and the mental health difficulties resulting from moral injury can be particularly challenging to treat. Yet little is known about the impact of moral injury on the well-being of UK armed forces (AF) veterans and how moral injury is currently addressed in treatment. Objective: The aim of this study was to examine UK AF veterans' experiences of moral injury, and the perceptions and challenges faced by clinicians in treating moral injury-related mental health difficulties. Method: Six veterans who reported moral injury exposure and four clinicians who had treated veterans with moral injury were recruited from Combat Stress. Semi-structured qualitative interviews were conducted and data were analysed using thematic analysis. Results: Moral injury was perceived by clinicians to be common in UK AF veterans and, where present, had a considerable negative impact on mental health. Clinicians reported a lack of a manualized approach for treating cases of moral injury and, instead, used a combination of several non-post-traumatic stress disorder (PTSD)-specific therapies. Providing treatment for morally injured veterans could be challenging given the limited number of sessions that clinicians were able to provide. Moreover, moral injury was thought to be poorly understood among UK AF veteran clinical care teams. Conclusion: This study provides some of the first insight into the impact of moral injury on UK AF veteran well-being as well as clinician views of delivering psychological care following moral injury. These findings highlight that moral injury is experienced by UK AF veterans, and further examination of the prevalence of moral injury and whether current treatment approaches are appropriate and efficacious is needed.

A Qualitative Examination of VA Chaplains' Understandings and Interventions Related to Moral Injury in Military Veterans

This study examines VA chaplains' understandings of moral injury (MI) and preferred intervention strategies. Drawing qualitative responses with a nationally-representative sample, content analyses indicated that chaplains' definitions of MI comprised three higher order clusters: (1) MI events, (2) mechanisms in development of MI, and (3) warning signs of MI. Similarly, chaplains' intervention foci could be grouped into three categories: (1) pastoral/therapeutic presence, (2) implementing specific interventions, and (3) therapeutic processes to promote moral repair. Findings are discussed related to emerging conceptualizations of MI, efforts to adapt existing evidence-based interventions to better address MI, and the potential benefits of better integrating chaplains into VA mental health service delivery.

PTSD From a Suicide Attempt: Phenomenological and Diagnostic Considerations

OBJECTIVE

A suicide attempt is at least somewhat life-threatening by definition and is, for some, traumatic. Thus, it is possible that some individuals may develop posttraumatic stress disorder (PTSD) from a suicide attempt.

METHOD

In this article, we consider whether one's suicide attempt could fulfill Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for a PTSD Criterion A event and contribute to the development of attendant PTSD symptoms (e.g., flashbacks, avoidance, shame/guilt, nightmares); discuss theoretical models of PTSD as they relate to suicide attempts; reflect on factors that might influence rates of suicide attempt-related PTSD; highlight methodological limitations that have hampered our understanding of suicide attempt-related PTSD; and posit areas for future scientific and clinical inquiry.

RESULTS

Strikingly, the degree to which a suicide attempt leads to PTSD is unknown.

CONCLUSIONS

We conclude with a call for research to systematically assess for suicide attempts alongside other potentially traumatic experiences (e.g., combat exposure, rape) that are included in standardized PTSD assessments.

Relationship Between Spiritual Well-being and Post-traumatic Stress Disorder Symptoms in United States Air Force Remotely Piloted Aircraft and Intelligence Personnel

BACKGROUND

Remotely piloted aircraft (RPA) are in frequent use by the U.S. Air Force to engage in combat operations from remote locations. RPA operations involve remote killing, which can lead to significant emotional responses. This study addresses a gap in research by examining the association of existential and spiritual health with post-traumatic stress disorder (PTSD) symptoms in RPA and intelligence personnel.

METHODS

Three hundred and five U.S. Air Force RPA and intelligence personnel completed the Spiritual Well-Being Scale (SWBS) and PTSD Checklist-Military Version. Correlational analyses were used to examine the association between SWBS score and PTSD symptoms.

FINDINGS

There was a negative correlation between the SWBS and PTSD Checklist-Military Version scores (Pearson correlation coefficient = -0.49, p < 0.0001). Higher spiritual and existential well-being were associated with lower PTSD symptoms. Further, spiritual and existential scores in this sample were comparable with a number of SWBS norms, suggesting that levels of existential distress may not be high among remote warfare operators.

DISCUSSION

In this sample of U.S. Air Force personnel involved in remote warfare, higher spiritual and existential well-being were associated with less endorsement of mental health symptoms on a PTSD symptom measure. Additionally, levels of spiritual and existential well-being in this sample were comparable with norms used in a number of samples within the general population. Although there are ongoing concerns regarding the psychological impact remote warfare has on RPA operators, the bulk of current research has indicated that operational stressors such as workload, rotating shifts, organizational and leadership concerns, and balancing work and domestic tasks rather than the job duties themselves (i.e., involvement in killing) likely contribute more to reported emotional distress levels.

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.

Deployment of personnel to military operations: impact on mental health and social functioning

This Campbell systematic review examines the effects of deployment on mental health. The review summarizes evidence from 185 studies. All studies used observational data to quantify the effect of deployment. This review includes studies that evaluate the effects of deployment on mental health. A total of 185 studies were identified. However, only 40 of these were assessed to be of sufficient methodological quality to be included in the final analysis. The studies spanned the period from 1993 to 2017 and were mostly carried out in the USA, UK and Australia. The studies all had some important methodological weaknesses. None of the included studies used experimental designs (random assignment). Deployment to military operations negatively affects the mental health functioning of deployed military personnel. For assessments taken more than 24 months since exposure, we consistently found adverse effects of deployment on all mental health domains (PTSD, depression, substance abuse/dependence, and common mental disorders), particularly on PTSD. For assessments taken less than 24 months (or a variable number of months since exposure) the evidence was less consistent and in many instances inconclusive.

Plain language summary

Deployment to military operations negatively affects the mental health functioning of deployed military personnel: While additional research is needed, the current evidence strongly supports the notion that deployment negatively affects mental health functioning of deployed military personnel.What is this review about?: When military personnel are deployed to military operations abroad they face an increased risk of physical harm, and an increased risk of adverse shocks to their mental health.The primary condition under consideration is deployment to an international military operation. Deployment to a military operation is not a uniform condition; rather, it covers a range of scenarios. Military deployment is defined as performing military service in an operation at a location outside the home country for a limited time period, pursuant to orders.The review included studies that reported outcomes for individuals who had been deployed. This review looked at the effect of deployment on mental health outcomes. The mental health outcomes are: post-traumatic stress disorder (PTSD), major depressive disorder (MDD), common mental disorders (depression, anxiety and somatisation disorders) and substance-related disorders.By identifying the major effects of deployment on mental health and quantifying these effects, the review can inform policy development on deployment and military activity as well as post-deployment support for veterans. In this way the review enables decision-makers to prioritise key areas.What are the main findings of this review?: What studies are included?: This review includes studies that evaluate the effects of deployment on mental health. A total of 185 studies were identified. However, only 40 of these were assessed to be of sufficient methodological quality to be included in the final analysis. The studies spanned the period from 1993 to 2017 and were mostly carried out in the USA, UK and Australia. The studies all had some important methodological weaknesses. None of the included studies used experimental designs (random assignment).Does deployment have an effect on mental health?: Deployment to military operations negatively affects the mental health functioning of deployed military personnel. For assessments taken more than 24 months since exposure, we consistently found adverse effects of deployment on all mental health domains (PTSD, depression, substance abuse/dependence, and common mental disorders), particularly on PTSD. For assessments taken less than 24 months (or a variable number of months since exposure) the evidence was less consistent and in many instances inconclusive.What do the findings of this review mean?: The odds of screening positive for PTSD and depression were consistently high in the longer term. This suggests that efforts should be increased to detect and treat mental disorders, as effects may be long-lasting.Overall the risk of bias in the majority of included studies was high. While it is difficult to imagine a randomised study design to understand how deployment affects mental health, other matters such as changes to personnel policy, or unanticipated shocks to the demand for military personnel, could potentially be a rich source of quasi-experimental variation.How up-to-date is this review?: The review authors searched for studies up to 2017. This Campbell systematic review was published in March 2018.

Executive summary

BACKGROUND: When military personnel are deployed to military operations abroad they face an increased risk of physical harm, and an increased risk of adverse shocks to their mental health. Research suggests that the increased risk to mental health is mainly due to the hazards of war, combat exposure: firing weapons, road side bombs, seeing fellow soldiers, friends, civilians, and enemies being injured, maimed or killed. These experiences may lead to severe mental stress. The adverse impact on mental health is the psychological cost of war, and it is of interest to policymakers to learn the magnitude of these effects. This review sets out to synthesise available evidence about the consequences of deployment for deployed military personnel in the mental health and social functioning domains.OBJECTIVES: The objective of this review isto synthesise the consequences of deployment to military operation on the mental health and social functioning of deployed military personnel.SEARCH METHODS: We searched electronic databases, grey literature, and references from primary studies and related reviews. No language or date restrictions were applied to the searches. We searched the following electronic databases: Academic Search Elite, Cochrane Library, EMBASE, ERIC, MEDLINE, PsycINFO, Science Citation Index, Social Science Citation Index, SocINDEX, as well as the Nordic platforms: bibliotek.dk, BIBSYS, and LIBRIS. The conclusions of this review are based on the most recent searches performed. The last search was performed in April 2017.SELECTION CRITERIA: Primary studies had to meet the following inclusion criteria: Participants: The participants should be military personnel.Intervention: The condition should be deployment to a military operation.Comparison: The relevant comparisons were either comparing a) deployed military personnel to non-deployed military personnel, b) deployed military personnel to military personnel deployed elsewhere, for example personnel deployed to non-combat operations, c) military personnel deployed to the same operation but stratified by combat exposure.Outcomes: The study should report on one or more mental health outcomes, and/or social functioning for the deployed participants. In particular studies should report on one or more of the following mental health outcomes: PTSD, major depression, substance abuse or dependence (including alcohol), and common mental disorders (depression and anxiety disorders). The following social functioning outcomes were relevant: employment, and homelessness.Study Designs: Both experimental and quasi-experimental designs with a comparison group were eligible for inclusion in the review. Studies were excluded if they: Reported on deployments taking place before 1989.Used a within group pre-post study design.Did not report on at least one of the mental health or social functioning outcomes. DATA COLLECTION AND ANALYSIS: The total number of potentially relevant studies constituted31,049records. A total of 185 studies met the inclusion criteria and were critically appraised by the review authors. The final selection of 185 studies was from 13 different countries.Forty eight of the 185 studies did not report effect estimates or provide data that would allow the calculation of an effect size and standard error. Fifty four studies were excluded because of overlapping samples. The majority of those studies were from USA but the main reason for not using studies from USA in the synthesis was lack of information to calculate an effect size. Nearly half the studies from the UK could not be used in the synthesis due to overlap of data samples. Forty three studies were judged to have a very high risk of bias (5 on the scale) and, in accordance with the protocol, we excluded these from the data synthesis on the basis that they would be more likely to mislead than inform., Thus a total of 40 studies, from five different countries, were included in the data synthesis.Random effects models were used to pool data across the studies. We used the odds ratio. Pooled estimates were weighted with inverse variance methods, and 95% confidence intervals were calculated. The meta-analyses were carried out by time since exposure (short, medium, long, and other time since exposure) and by type of comparison (deployed versus non-deployed, all deployed but stratified by either combat operations versus non-combat operations, or stratified by combat exposure). We performed single factor subgroup analysis. The assessment of any difference between subgroups was based on 95% confidence intervals. Funnel plots were used to assess the possibility of publication bias. Sensitivity analysis was used to evaluate whether the pooled effect sizes were robust across components of methodological quality.MAIN RESULTS: The findings were mixed, depending on the outcome, the time since exposure and the approach (deployed versus non-deployed termed absolute or stratified by extent of combat termed relative) used to investigate the effect. It was not possible to analyse the outcomes homelessness and employment. All studies that could be used in the data synthesis reported on the impact of deployment on mental health; PTSD, depression, substance use or common mental disorder.For assessments taken less than 24 months since exposure the evidence was inconclusive either because too few studies reported results in the short and medium term and/or the degree of heterogeneity between studies was large.For assessments taken at other time points (a variable number of months since exposure) the evidence was inconclusive for the relative comparisons due to either too few studies or a substantial degree of heterogeneity between studies. For the absolute comparison the analysis of common mental disorder was inconclusive, whereas the average effects of PTSD and depression were positive and statistically significant (PTSD odds ratio (OR) was 1.91 (95% confidence interval (CI): 1.28 to 2.85) and OR=1.98 (95% CI: 1.05 to 3.70) for depression). The analysis concerning substance use indicated that deployed participants did not have higher odds of screening positive for substance use compared to non-deployed participants (OR=1.15 (95% CI: 0.98 to 1.36)).For assessments taken more than 24 months post exposure, meta-analyses indicated that the odds of screening positive for PTSD, depression, substance use and common mental disorder were higher for participants in the deployed group compared to participants in the group that were not deployed (PTSD OR=3.31 (95% CI: 2.69 to 4.07), OR=2.19 (95% CI: 1.58 to 3.03) for depression, OR=1.27 (95% CI: 1.15 to 1.39) for substance use, and OR=1.64 (95% CI: 1.38 to 1.96) for common mental disorder). Likewise, participants reporting high combat exposure had higher odds of screening positive for PTSD and depression than participants reporting lower exposure for long term assessments (PTSD OR=3.05 (95% CI: 1.94 to 4.80) and OR=1.81 (95% CI: 1.28 to 2.56) for depression). The analyses of substance use and common mental disorder were inconclusive due to too few studies.On the basis of the prevalence of mental health problems in pre-deployed or non-deployed population based comparison sampleswe would therefore expect the long term prevalence of PTSD in post-deployed samples to be in the range 6.1 - 14.9%, the long term prevalence of depression to be in the range from 7.6% to 18%, the long term prevalence of substance use to be in the range from 2.4% to 17.5% and the prevalence of common mental disorder to be in the range from 10% to 23%.Sensitivity analyses resulted in no appreciable change in effect size, suggesting that the results are robust.It was only possible to assess the impact of two types of personnel characteristics (branch of service and duty/enlistment status) on the mental health outcomes. We found no evidence to suggest that the effect of deployment on any outcomes differ between these two types of personnel characteristics.AUTHORS' CONCLUSIONS: Deployment to military operations negatively affects the mental health functioning of deployed military personnel. We focused on the effect of deployment on PTSD (post-traumatic stress disorder), depression, substance abuse/dependence, and common mental disorders (depression and anxiety disorders). For assessments taken less than 24 months (or a variable number of months since exposure) the evidence was less consistent and in many instances inconclusive. For assessments taken more than 24 months since exposure, we consistently found adverse effects of deployment on all domains, particularly on PTSD. There is increased political awareness of the need to address post deployment mental health problems. The odds of screening positive for PTSD and depression were consistently high in the longer term. This suggests that efforts should be increased to detect and treat mental disorders, as effects may be long lasting. Mental illness is of particular concern in the military for operational reasons, but they may be hard to detect in the military setting because a military career is intimately linked with mental and physical strength.It was not possible to examine a number of factors which we had reason to expect would impact on the magnitude of the effect. This would have been particularly relevant from a policy perspective because these are direct parameters that one could use to optimally "organize" deployment in order to minimize impacts on mental health functioning.While additional research is needed, the current evidence strongly supports the notion that deployment negatively affects mental health functioning of deployed military personnel. The next step is to begin to examine preventive measures and policies for organizing deployment, in order to minimize the effects on mental health.

Psychometric Properties of a Modified Moral Injury Questionnaire in a Military Population

Moral injury (MI) results from perpetration of or exposure to distressing events, known as morally injurious events (MIEs), that challenge moral beliefs and values. Due to the type of involvement in recent military conflicts, many veterans report MIEs that may cause dissonance and, in turn, MI. Although two existing measures assess MIEs, neither currently assesses the defining characteristics of MI (i.e., guilt, shame, difficulty forgiving self and others, and withdrawal). The present study reports the initial psychometric test of a modified version (Robbins, Kelley, Hamrick, Bravo, & White, 2017) of the Moral Injury Questionnaire - Military version (MIQ-M; Currier, Holland, Drescher, & Foy, 2015) in a sample of 328 military personnel (e.g., veterans, National Guard/reservists, active duty members). The MIQ-M was modified to assess both MIEs and the defining characteristics of MI. Exploratory factor analyses suggested a three-factor model of MIEs consisting of Atrocities of war, Psychological consequences of war, and Leadership failure or betrayal. The modified MIQ-M factors were correlated with defining characteristics of MI. In addition, each MIE factor and associated defining characteristics of MI were positively correlated with symptoms of posttraumatic stress disorder, depression, and anxiety, as well as substance use. The modified MIQ-M is a reliable measure of MI that is comprised of three subscales that are associated with, but distinct from, mental health outcomes. Although findings are promising, further research evaluating the applicability of the modified MIQ-M in clinical settings is required to establish construct validity of the defining characteristics and secondary manifestations of MI.

"I knew it was wrong the moment I got the order": A narrative thematic analysis of moral injury in combat veterans

OBJECTIVE

Moral injury is a nascent construct intended to capture reactions to events that violate deeply held beliefs and moral values. Although a model of moral injury has been proposed, many of the theoretical propositions of this model have yet to be systematically studied.

METHOD

We conducted semistructured interviews with eight veterans who reported experiencing morally injurious events during war zone deployments.

RESULTS

Using narrative thematic analysis, five main themes and associated subthemes emerged from the data. The main themes capture the timing of the event, contextual factors that affected the decision-making process during the morally injurious event, reactions to the moral injurious event, search for purpose and meaning, and opening up.

CONCLUSION

The findings from the present study supported an existing model of moral injury, while extending it in several important ways. Preliminary clinical recommendations and directions for future research are discussed based on the study findings. These include directly exploring the context surrounding the morally injurious event, examining the veterans' moral appraisals, and helping them assume appropriate responsibility for their actions to reduce excessive self-blame.

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.

Euthanasia of Cattle: Practical Considerations and Application

Simple Summary

Methods recognized as acceptable for the euthanasia of cattle include overdose of an anesthetic, gunshot and captive bolt. The most common injectable anesthetic agent used for euthanasia is pentobarbital and while it may be the preferred method for euthanasia in sensitive situations, it creates significant challenges for disposal of animal remains. Gunshot and captive bolt are the more common methods used on farms and ranches because they are inexpensive, humane and do not complicate carcass disposal. Firearms must be of the proper caliber and loaded with the proper ammunition. Captive bolt, equipped with a penetrating bolt, is to be used on adult animals, whereas the non-penetrating (mushroom head) bolt should be reserved for use in calves (three months of age or less). In addition to selection of the proper firearm or captive bolt, successful euthanasia requires use of the proper anatomic site and adjunctive steps to assure death. The indicators of unconsciousness and death must be clearly understood and confirmed in all situations involving euthanasia. Tools for the efficient depopulation of a large feedlot, dairy or beef cattle operation as may be required in a national animal health emergency situation have been developed and validated as effective. Finally, the human impact of euthanasia cannot be underestimated. Symptoms of mental illness including depression, grief, sleeplessness and destructive behaviors including alcoholism and drug abuse are not uncommon for those who participate in the euthanasia of animals.

Abstract

Acceptable methods for the euthanasia of cattle include overdose of an anesthetic, gunshot and captive bolt. The use of anesthetics for euthanasia is costly and complicates carcass disposal. These issues can be avoided by use of a physical method such as gunshot or captive bolt; however, each requires that certain conditions be met to assure an immediate loss of consciousness and death. For example, the caliber of firearm and type of bullet are important considerations when gunshot is used. When captive bolt is used, a penetrating captive bolt loaded with the appropriate powder charge and accompanied by a follow up (adjunctive) step to assure death are required. The success of physical methods also requires careful selection of the anatomic site for entry of a “free bullet” or “bolt” in the case of penetrating captive bolt. Disease eradication plans for animal health emergencies necessitate methods of euthanasia that will facilitate rapid and efficient depopulation of animals while preserving their welfare to the greatest extent possible. A portable pneumatic captive bolt device has been developed and validated as effective for use in mass depopulation scenarios. Finally, while most tend to focus on the technical aspects of euthanasia, it is extremely important that no one forget the human cost for those who may be required to perform the task of euthanasia on a regular basis. Symptoms including depression, grief, sleeplessness and destructive behaviors including alcoholism and drug abuse are not uncommon for those who participate in the euthanasia of animals.

Alcohol Misuse in Reserve Soldiers and their Partners: Cross-Spouse Effects of Deployment and Combat Exposure

BACKGROUND

Military deployment and combat are associated with worse outcomes, including alcohol misuse. Less is known about how these experiences affect soldiers' spouses.

OBJECTIVE

The study objective was to explore relationships between deployment, combat exposure, and alcohol misuse; especially cross-spouse effects (effect of one partner's experiences/behavior on the other partner), which has been under-examined in military samples.

METHODS

U.S. Army Reserve/National Guard soldiers and their partners completed a questionnaire covering physical and mental health, military service and substance use. Negative binomial regression models examined number of deployments and combat exposure individually for alcohol misuse and frequent heavy drinking (FHD). In additional models, we examined combat exposure's role on alcohol outcomes, controlling for the soldiers' number of deployments, PTSD symptoms, age, and in cross-spouse models, alcohol use and FHD. We considered individuals' deployment experiences related to their alcohol outcomes and to their spouses' alcohol outcomes.

RESULTS

The study sample included male soldiers with current/lifetime military service (n = 248) and their female partners. Combat exposure was related to FHD (RR: 1.01, p < .05, 95% CI: 1.01, 1.01) among male soldiers while controlling for PTSD symptoms, number of deployments, and age. Female partners of male soldiers were more likely to engage in FHD (RR: 1.01, p < .05, 95% CI: 1.01, 1.01) if their spouse experienced combat.

CONCLUSIONS

Our results demonstrate that male soldiers and their spouses are at increased risk of FHD if the soldier experienced combat. This points to the need for better screening, particularly of spouses of soldiers, whose alcohol misuse may be overlooked.

Measuring Aggregated and Specific Combat Exposures: Associations Between Combat Exposure Measures and Posttraumatic Stress Disorder, Depression, and Alcohol-Related Problems

Research has shown combat exposure to be associated with negative mental health outcomes. Different combat exposure measures are not composed of the same combat experiences, and few combat exposure measures have been directly compared to another measure. Furthermore, research about the unique associations between specific combat experiences and mental health is lacking. We investigated associations between new-onset posttraumatic stress disorder (PTSD), new-onset depression, and alcohol-related problems and two commonly used measures of combat among a sample of 20,719 recently deployed U.S. military personnel. A 13-item measure assessed both direct and indirect combat exposures, and a 5-item measure assessed only indirect exposures. Both combat measures were associated with all outcomes in the same direction (e.g., PTSD, odds ratio [OR] = 2.97 vs. 4.01; depression, OR = 2.03 vs. 2.42; alcohol-related problems, OR = 1.41 vs. 1.62, respectively, for the 5- and 13-item measures). The 13-item measure had a stronger association with some outcomes, particularly PTSD. Each specific item had significant bivariate associations with all outcomes, ORs = 1.43-4.92. After adjusting for other combat exposures, items assessing witnessing abuse, feeling in danger, and knowing someone injured or killed remained associated with all outcomes, ORs = 1.18-2.72. After this adjustment, several items had unexpected protective associations with some mental health outcomes. Results indicated these two combat exposure measures were approximately equally effective for determining risk for negative mental health outcomes in a deployed population, despite having different content. Additional research is needed to replicate and understand how specific combat exposures affect health.

Distinct Trauma Types in Military Service Members Seeking Treatment for Posttraumatic Stress Disorder

We examined the frequency of trauma types reported in a cohort of service members seeking treatment for posttraumatic stress disorder (PTSD) and compared symptom profiles between types. In this observational study, 999 service members (9.2% women; M_age = 32.91 years; 55.6% White) were evaluated using a standardized assessment procedure to determine eligibility for clinical trials. Participants were evaluated for DSM-IV-TR-defined PTSD using the PTSD Symptom Scale-Interview; all participants reported a Criterion A event. Independent evaluators rated descriptions of Criterion A events as belonging to trauma types at a high degree of reliability, κ = 0.80. Aggregated non-life-threat primary trauma types were more frequently endorsed than aggregated life-threat types, 95% CI [17.10%, 29.20%]. Participants who endorsed moral injury-self traumas had a higher level of reexperiencing (d = 0.39), guilt (hindsight bias, d = 1.06; wrongdoing, d = 0.93), and self-blame (d = 0.58) symptoms, relative to those who reported life threat-self. Participants who experienced traumatic loss had greater reexperiencing (d = 0.39), avoidance (d = 0.22), guilt (responsibility, d = 0.39), and greater peri- and posttraumatic sadness (d = 0.84 and d = 0.70, respectively) symptoms, relative to those who endorsed life threat-self. Relative to life threat-self, moral injury-others was associated with greater peri- (d = 0.36) and posttraumatic (d = 0.33) betrayal/humiliation symptoms, and endorsement of aftermath of violence was associated with greater peri- (d = 0.84) and posttraumatic sadness (d = 0.57) symptoms. War zone traumas were heterogeneous, and non-life-threat traumas were associated with distinct symptoms and problems.

Greater prevalence of post-traumatic stress disorder and depression in deployed Canadian Armed Forces personnel at risk for moral injury

BACKGROUND

A link between moral injury (i.e., the psychological distress caused by perceived moral transgressions) and adverse mental health outcomes (AMHO) has been recently proposed. However, the prevalence of exposure to morally injurious events and the associated risk of experiencing AMHO remains understudied.

METHOD

The impact of exposure to potentially morally injurious experiences (PMIEs) was explored in relation to past-year PTSD and MDD, using the 2013 Canadian Armed Forces Mental Health Survey dataset of Afghanistan mission deployed regular force and reserve personnel. A series of logistic regressions were conducted, controlling for relevant sociodemographic, military, deployment, and trauma-related variables.

RESULTS

Over half of the deployed personnel endorsed at least one PMIE. Several demographic and military variables were associated with exposure to PMIEs. Those exposed to PMIEs demonstrated a greater likelihood of having past-year PTSD and MDD; feeling responsible for the death of Canadian or ally personnel demonstrated the strongest association with PTSD and MDD. Mental health training was not a moderator for PMIE exposure and AMHO.

CONCLUSIONS

Exposure to PMIEs during deployments is common and represents an independent risk factor for past-year PTSD and MDD. Improved training that targets moral-ethical dilemmas and treatment interventions that address moral injury expressions is warranted.

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.

Perpetrating Violence Increases Identification With Violent Groups: Survey Evidence From Former Combatants

Heightened group identification motivates individuals to perpetrate violence, but can perpetrating violence-in and of itself-increase identification with violent groups? I test this idea using archival surveys of ex-combatants. In Liberia, where many combatants joined their violent group willingly, the data show a positive association between perpetrating violence and identification with one's violent group (Study 1). These results hold even when controlling for potentially confounding variables such as being abducted into the group versus joining willingly, length of time in the group, and personally experiencing violence. Study 2 replicates and extends this finding with data from ex-combatants in Uganda who were abducted into their group, using a natural experiment in which some abductees were forced to perpetrate violence whereas other abductees were not. These findings support a cycle of violence in which perpetrating violence increases identification with violent groups and heightened identification increases future violent behavior.

Moral Injury: Contextualized Care

Amidst the return of military personnel from post-9/11 conflicts, a construct describing the readjustment challenges of some has received increasing attention: moral injury. This term has been variably defined with mental health professionals more recently conceiving of it as a transgression of moral beliefs and expectations that are witnessed, perpetrated, or allowed by the individual. To the extent that morality is a system of conceptualizing right and wrong, individuals' moral systems are in large measure developmentally and socially derived and interpreted. Thus, in seeking to provide care and aid in reintegration for combat veterans, it is necessary to consider communities that have contributed to an individual's formation and that might have participated in the interpretation of his/her suffering. This can take many forms, but given that morality is often complexly intertwined with issues of religion, faith, and spirituality for many individuals, and recognizing that much of the current focus on moral injury is emanating out of healthcare contexts, we devote particular attention to how chaplains might be more intentionally engaged in healthcare systems such as the Veterans Health Administration to provide non-judgmental, person-centered, culturally-relevant care rooted in communities of practice to veterans with moral injury.

A Review of Military Health Research Using a Social–Ecological Framework

Objective:

We aim to contextualize the growing body of research on the sequelae of military service in the wars in Afghanistan and Iraq. We employ a social–ecological (SE) framework for the taxonomy of military health research and classify risk as arising from the individual, family, community, and the institutional levels. We intend for this review to inform enhanced health promotion efforts in military communities.

Data Source:

Articles reviewed were extracted from Web of Science, PubMed, and Scopus.

Inclusion and Exclusion Criteria:

Research focused on somatic and psychological sequelae of combat deployment published from 2001—the year the war in Afghanistan began—through the end of 2014. We excluded studies of non-US military personnel, other systematic reviews, meta-analyses, book chapters, and theoretical papers.

Data Extraction:

We examined and summarized the aims, participants, methods, study design, SE framework tier, risk factors, and health outcomes.

Data Synthesis:

Studies were categorized according to SE tier, whether they focused on somatic, behavioral, or psychological outcomes, and by risk factor.

Results:

Of the 352 peer-reviewed papers, 84% focused on war’s sequelae on the index military personnel, and 75% focused on mental or behavioral health outcomes—mostly on post-traumatic stress disorder. We find comparatively little research focusing on the family, community, or institutional tiers.

Conclusions:

We know relatively little about how family and community respond to the return of personnel from combat deployment; how family resources affect the health of returning military personnel; and how a war’s persistence presents challenges for federal, state, and local agencies to meet military health-care needs. Such work is especially salient as US troops return home from war—particularly in communities where there are substantial military populations.

"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.

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.

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

Web-based alcohol intervention for veterans: PTSD, combat exposure, and alcohol outcomes

OBJECTIVE

The purpose of the current study was to evaluate the relationship between baseline levels of posttraumatic stress disorder (PTSD), combat exposure, and alcohol outcomes in a sample of Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans using a web-based self-management intervention (VetChange) for problem drinking.

METHOD

The current study focuses on 523 veterans who participated in a larger randomized clinical trial. Analyses in the current study include (a) multivariable linear regression models to assess the relationship between PTSD, combat exposure, and alcohol variables at baseline, and (b) general linear models accounting for correlated data within subjects to analyze change over time for alcohol outcomes as a function of baseline PTSD symptoms, combat exposure, and covariates.

RESULTS

There was a positive association between PTSD symptom severity and alcohol use and alcohol problem severity at baseline. However, participants with higher baseline PTSD symptoms demonstrated a significantly greater reduction in alcohol use during the intervention and a greater reduction in alcohol problems from baseline to 3-month follow-up. Combat exposure severity was positively associated with alcohol problems at baseline. However, veterans with higher exposure demonstrated a greater reduction in average weekly drinking between end of intervention and follow-up, and otherwise showed changes similar to participants with lower exposure.

CONCLUSIONS

Higher levels of baseline PTSD symptoms and combat exposure severity did not prevent OEF/OIF veterans from achieving positive alcohol outcomes through participation in a self-management web intervention for problem drinking. (PsycINFO Database Record

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.

Time-course of PTSD symptoms in the Australian Defence Force: a retrospective cohort study

AIMS

Understanding the time-course of post-traumatic stress disorder (PTSD), and the underlying events, may help to identify those most at risk, and anticipate the number of individuals likely to be diagnosed after exposure to traumatic events.

METHOD

Data from two health surveys were combined to create a cohort of 1119 Australian military personnel who deployed to the Middle East between 2000 and 2009. Changes in PTSD Checklist Civilian Version (PCL-C) scores and the reporting of stressful events between the two self-reported surveys were assessed. Logistic regression was used to examine the association between the number of stressful events reported and PTSD symptoms, and assess whether those who reported new stressful events between the two surveys, were also more likely to report older events. We also assessed, using linear regression, whether higher scores on the Kessler Psychological Distress Scale or the Alcohol Use Disorder Identification Test were associated with subsequent increases in the PCL-C in those who had experienced a stressful event, but who initially had few PTSD symptoms.

RESULTS

Overall, the mean PCL-C scores in the two surveys were similar, and 78% of responders stayed in the same PCL-C category. Only a small percentage moved from having few symptoms of PTSD (PCL-C < 30) in Survey 1 to meeting the criteria for PTSD (PCL-C ≥ 50) at Survey 2 (1% of all responders, 16% of those with PCL-C ≥ 50 at Survey 2). Personnel who reported more stressful lifetime events were more likely to score higher on the PCL-C. Only 51% reported the same stressful event on both surveys. People who reported events occurring between the two surveys were more likely to record events from before the first survey which they had not previously mentioned (OR 1.48, 95% CI (1.17, 1.88), p < 0.001), than those who did not. In people who initially had few PTSD symptoms, a higher level of psychological distress, was significantly associated with higher PCL-C scores a few years later.

CONCLUSIONS

The reporting of stressful events varied over time indicating that while the impact of some stressors endure, others may increase or decline in importance. When screening for PTSD, it is important to consider both traumatic experiences on deployment and other stressful life events, as well as other mental health problems among military personnel, even if individuals do not exhibit symptoms of PTSD on an initial assessment.

Rates and consequences of posttraumatic distress among American Indian adults with type 2 diabetes

This study examined the prevalence of screened posttraumatic stress disorder (PTSD) and associated diabetes-related outcomes. A sample of American Indian adults with type 2 diabetes (n = 218) participated in interviewer-administered surveys. Using a cutoff of 3 on the Primary Care PTSD screener, 21.8 % of participants screened positive for PTSD. PTSD symptoms were negatively associated with self-rated health status and positively associated with past year hospitalization after controlling for several demographic factors, but not after controlling for depressive symptoms. Past month frequency of hyperglycemia symptoms was not related to PTSD symptoms. When grouped by mental health conditions (neither screened PTSD nor depressive symptoms, screened PTSD only, depressive symptoms only, and both), those with both screened PTSD and depressive symptoms reported the highest proportion of any past month hyperglycemia, past year hospitalization, and low self-rated health status. Screened PTSD, especially in those with comorbid depressive symptoms, is an important consideration in diabetes care.

Drinking to ease the burden: a cross-sectional study on trauma, alcohol abuse and psychopathology in a post-conflict context

BACKGROUND

It is likely that alcohol use and abuse increase during and after violent conflicts. The most prominent explanation of this phenomenon has been referred to as self-medication hypothesis. It predicts that psychotropic substances are consumed to deal with conflict-related psychic strains and trauma. In northern Uganda, a region that has been affected by a devastating civil war and is characterized by high levels of alcohol abuse we examined the associations between war-trauma, childhood maltreatment and problems related to alcohol use. Deducing from the self-medication hypothesis we assumed alcohol consumption moderates the relationship between trauma-exposure and psychopathology.

METHODS

A cross-sectional epidemiological survey targeting war-affected families in post-conflict northern Uganda included data of male (n = 304) and female (n = 365) guardians. We used standardized questionnaires in an interview format to collect data on the guardians' socio-demography, trauma-exposure, alcohol consumption and symptoms of alcohol abuse, PTSD and depression.

RESULTS

Symptoms of current alcohol use disorders were present in 46 % of the male and 1 % of the female respondents. A multiple regression model revealed the unique contributions of emotional abuse in the families of origin and trauma experienced outside the family-context in the prediction of men's alcohol-related symptoms. We found that alcohol consumption moderated the dose-effect relationship between trauma-exposure and symptoms of depression and PTSD. Significant interactions indicated that men who reported more alcohol-related problems experienced less increase in symptoms of PTSD and depression with increasing trauma-exposure.

CONCLUSIONS

The gradual attenuation of the dose-effect the more alcohol-related problems were reported is consistent with the self-medication hypothesis. Hence, the functionality of alcohol consumption has to be considered when designing and implementing addiction treatment in post-conflict contexts.

Help-Seeking Behaviors Among Active-Duty Military Personnel: Utilization of Chaplains and Other Mental Health Service Providers

Military chaplains not only conduct religious services, but also provide counseling and spiritual support to military service members, operating as liaisons between soldiers and mental health professionals. In this study, active-duty soldiers (N = 889) reported help-seeking behaviors and mental health. Using logistic regressions, we describe the issues for which soldiers reported seeking help, then outline the characteristics of those who are most likely to seek help from a chaplain. Of the soldiers who sought help from a chaplain within the previous year, 29.9% reported high levels of combat exposure, 50.8% screened positive for depression, 39.1% had probable PTSD, and 26.6% screened positive for generalized anxiety disorder. The participant’s unit firing on the enemy, personally firing on the enemy, and seeing dead bodies or human remains predicted seeing a chaplain. Future research should examine ways to engage soldiers who have had more combat experiences with the chaplain community to address spiritual issues.

Unit cohesion, traumatic exposure and mental health of military personnel

BACKGROUND

The benefit of military unit cohesion to morale and psychological resilience is well established. But it remains unclear whether unit cohesion modifies the association between deployment-related traumatic exposure and mental health problems.

AIMS

To examine the association between unit cohesion, traumatic exposure and poor mental health [symptoms of post-traumatic stress disorder (PTSD), psychological distress and alcohol dependency] and assess whether the relationship between traumatic exposure and poor mental health differs by level of unit cohesion.

METHODS

A self-reported cross-sectional survey of Australian military personnel deployed to Iraq or Afghanistan between 2001 and 2009.

RESULTS

Among 11411 participants, those with low levels of unit cohesion had higher odds of PTSD symptoms [aOR (95% CI): 2.54 (1.88, 3.42)], very high psychological distress [aOR (95% CI): 4.28 (3.04, 6.02)] and a high level of alcohol problems [aOR (95% CI): 1.71 (1.32, 2.22)] compared with those reporting high unit cohesion on deployment. Higher exposure to traumatic events on deployment was associated with greater risk of PTSD symptoms, very high levels of psychological distress and high levels of alcohol problems in this cohort. However, there was no evidence of a statistically significant interaction between unit cohesion and traumatic exposures in influencing poor mental health.

CONCLUSIONS

Our findings suggest that both unit cohesion and traumatic exposure are independently associated with poor mental health. Efforts to improve military unit cohesion may help to improve the mental health resilience of military personnel, regardless of their level of traumatic exposure.

Discriminatory experiences associated with posttraumatic stress disorder symptoms among transgender adults

Discrimination has been shown to disproportionately burden transgender people; however, there has been a lack of clinical attention to the mental health sequelae of discrimination, including posttraumatic stress disorder (PTSD) symptoms. Additionally, few studies contextualize discrimination alongside other traumatic stressors in predicting PTSD symptomatology. The current study sought to fill these gaps. A community-based sample of 412 transgender adults (mean age 33, SD = 13; 63% female-to-male spectrum; 19% people of color; 88% sampled online) completed a cross-sectional self-report survey of everyday discrimination experiences and PTSD symptoms. Multivariable linear regression models examined the association between self-reported everyday discrimination experiences, number of attributed domains of discrimination, and PTSD symptoms, adjusting for prior trauma, sociodemographics, and psychosocial comorbidity. The mean number of discrimination attributions endorsed was 4.8 (SD = 2.4) and the 5 most frequently reported reasons for discrimination were: gender identity and/or expression (83%), masculine and feminine appearance (79%), sexual orientation (68%), sex (57%), and age (44%). Higher everyday discrimination scores (β = 0.25; 95% CL [0.21, 0.30]) and greater number of attributed reasons for discrimination experiences (β = 0.05; 95% CL [0.01, 0.10]) were independently associated with PTSD symptoms, even after adjusting for prior trauma experiences. Everyday discrimination experiences from multiple sources necessitate clinical consideration in treatment for PTSD symptoms in transgender people. (PsycINFO Database Record

The Effect of Distance on Moral Engagement: Event Related Potentials and Alpha Power are Sensitive to Perspective in a Virtual Shooting Task

In a shooting video game we investigated whether increased distance reduces moral conflict. We measured and analyzed the event related potential (ERP), including the N2 component, which has previously been linked to cognitive conflict from competing decision tendencies. In a modified Go/No-go task designed to trigger moral conflict participants had to shoot suddenly appearing human like avatars in a virtual reality scene. The scene was seen either from an ego perspective with targets appearing directly in front of the participant or from a bird's view, where targets were seen from above and more distant. To control for low level visual features, we added a visually identical control condition, where the instruction to "shoot" was replaced by an instruction to "detect." ERP waveforms showed differences between the two tasks as early as in the N1 time-range, with higher N1 amplitudes for the close perspective in the "shoot" task. Additionally, we found that pre-stimulus alpha power was significantly decreased in the ego, compared to the bird's view only for the "shoot" but not for the "detect" task. In the N2 time window, we observed main amplitude effects for response (No-go > Go) and distance (ego > bird perspective) but no interaction with task type (shoot vs. detect). We argue that the pre-stimulus and N1 effects can be explained by reduced attention and arousal in the distance condition when people are instructed to "shoot." These results indicate a reduced moral engagement for increased distance. The lack of interaction in the N2 across tasks suggests that at that time point response execution dominates. We discuss potential implications for real life shooting situations, especially considering recent developments in drone shootings which are per definition of a distant view.

International military operations and mental health--A review

BACKGROUND

Volunteering in international military missions has been scrutinized for its effects on mental health. Different kinds of exposures to traumatic events are associated with a variety of mental disorders, mainly heightened rates of post-traumatic stress disorder (PTSD) and alcohol abuse.

AIMS

Based on the literature we discuss risk and protective factors concerning the psychological well-being of soldiers attending to international military operations.

METHODS

A systematic literature search was carried out using relevant search terms to identify the articles for this review.

RESULTS AND CONCLUSIONS

The ability to recognize and treat acute stress reactions during deployments is important. Post-deployment psychosocial support and services have a role in lowering barriers to care, diminishing stigma and also in recognizing individuals who suffer from psychological distress or psychiatric symptoms, to connect them with appropriate care. Further investigation of gender differences and the role of stigmatization is warranted. Most of those participating in international military operations are repatriated without problems, but repeated exposure to combat situations and other stressors may affect mental health in various ways. Stigmatization is still a barrier to care.

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.
