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.

Military occupation as a moderator between combat exposure and posttraumatic stress disorder symptoms in US Army personnel.

Military occupational designations are standardized classifications that help define and convey a service member's expected duties and responsibilities. The present study examined how occupational designation was related to adverse combat-reactions, specifically posttraumatic stress disorder (PTSD). It was hypothesized that at comparable levels of combat, non-combat units would display greater symptomology than combat units. The study sample consisted of 785 combat-deployed, active-duty enlisted US Army personnel. Participants were administered self-report questionnaires, including the Combat Experiences Scale and PTSD Checklist for DSM-5. Occupation was coded using the three-branch system (i.e., Operations, Support, & Force Sustainment). Hierarchical multiple linear regression (MLR) was run to examine the effect of occupation, combat, and unit cohesion on PTSD symptoms. Operations units reported the highest frequency of combat exposure; however, Force Sustainment units displayed the highest PTSD symptoms. In MLR analysis, there was a significant interaction between Force Sustainment units and combat exposure (ß = 0.10, p = .019), that was not observed in Operations or Support units. These findings demonstrate that PTSD symptom intensity is not solely a function of combat exposure, and that non-combat units may react differently when exposed to elevated levels of combat.

Aggression in US soldiers post-deployment: Associations with combat exposure and PTSD and the moderating role of trait anger.

Anger and aggression are among the most common issues reported by returning service members from combat deployments. However, the pathways between combat exposure and anger and aggression have not been comprehensively characterized. The present study aimed to characterize the relationship between trait anger, combat exposure, post-deployment PTSD, and aggression. U.S. Army soldiers (N = 2,420) were administered anonymous surveys assessing combat exposure, current PTSD symptoms and aggression, as well as trait anger items 3 months after returning from deployment to Afghanistan. PTSD symptom levels were related to aggression at higher levels of trait anger, but not evident among soldiers who had lower levels of trait anger. The pathway from combat exposure to PTSD, and then to aggression, was conditional upon levels of trait anger, such that the pathway was most evident at high levels of trait anger. This was the first study to our knowledge that concurrently modeled unconditional and conditional direct and indirect associations between combat exposure, PTSD, trait anger, and aggression. The findings can be helpful clinically and for developing screening protocols for combat exposed Soldiers. The results of this study suggest the importance of assessing and managing anger and aggression in soldiers returning from combat deployment. Anger is one of the most common complaints of returning soldiers and can have debilitating effects across all domains of functioning. It is imperative that future research efforts are directed toward understanding this phenomenon and developing and validating effective treatments for it.

APIRE Practice Research Network: accomplishments, challenges, and lessons learned.

The Practice Research Network (PRN) was established in 1993 to bridge the gap between the science base and the clinical practice of psychiatry by expanding the generalizability of findings and involving clinicians in the development and conduct of research. It began as a nationwide network of psychiatrists and has evolved to conduct large-scale, clinical and policy research studies using randomly selected samples of psychiatrists from the AMA Physician Masterfile. This paper provides an overview of major PRN initiatives and the impact of these studies. It describes the benefits to clinicians of participating in PRN research, as well as strategies developed to address key challenges.

Trends in mental health services utilization and stigma in US soldiers from 2002 to 2011.

OBJECTIVES: We characterized trends in mental health services utilization and stigma over the course of the Afghanistan and Iraq wars among active-component US soldiers. METHODS: We evaluated trends in mental health services utilization and stigma using US Army data from the Health-Related Behavior (HRB) surveys from 2002, 2005, and 2008 (n = 12,835) and the Land Combat Study (LCS) surveys administered to soldiers annually from 2003 to 2009 and again in 2011 (n = 22,627). RESULTS: HRB and LCS data suggested increased mental health services utilization and decreased stigma in US soldiers between 2002 and 2011. These trends were evident in soldiers with and without posttraumatic stress disorder (PTSD), major depressive disorder (MDD), or PTSD and MDD. Despite the improving trends, more than half of soldiers with mental health problems did not report seeking care. CONCLUSIONS: Mental health services utilization increased and stigma decreased over the course of the wars in Iraq and Afghanistan. Although promising, these findings indicate that a significant proportion of US soldiers meeting criteria for PTSD or MDD do not utilize mental health services, and stigma remains a pervasive problem requiring further attention.

Unethical battlefield conduct reported by soldiers serving in the Iraq war.

Research involving military service members has shown a strong relationship between combat experiences and increased risk for posttraumatic stress disorder (PTSD) and other mental health problems. Comparatively little research has examined the relationship between combat experiences, PTSD, aggression, and unethical conduct on the battlefield, although news stories sometimes suggest links between unethical conduct and disorders such as PTSD. This study systematically examined whether unethical conduct is a proxy for aggression and whether specific combat experiences and PTSD are independently associated with unethical behavior. The results of this study indicate that aggression (ß = 0.30) and specific combat experiences (particularly, witnessing war atrocities [ß = 0.14] and fighting [ß = 0.13]) are much more strongly associated with unethical conduct than is PTSD (ß = 0.04).

Associations of health care staff burnout with negative health and organizational outcomes in the U.S. military health system.

RATIONALE: Burnout is a personal and occupational phenomenon that has been associated with negative physical and psychological outcomes in medical staff. Additionally, there are implications for healthcare organizations, as those staff who are burned out are more likely to have lower productivity or leave the organization. As with the Covid-19 pandemic, future national emergencies and potentially large-scale conflicts will require similar and likely even larger scale responses from the U.S. Military Health System, thus it is important to understand burnout in this population so that the readiness of the staff and the military can remain at a high level. OBJECTIVE: This assessment was designed to examine levels of burnout among United States Military Health System (MHS) staff working at Army installations and the factors that influence the development of burnout. METHODS: Anonymous data was collected from 13,558 active-duty U.S. Soldiers and civilian MHS employees. Burnout was measured using the Copenhagen Burnout Inventory and the Mini-Z. RESULTS: Results showed nearly half of staff who responded (48%) reported being burned out, an increase since last measured in 2019 (31%). Factors related to increased burnout included concerns about work/life balance and workload, low job satisfaction and feeling disconnected from others. Burnout was associated with increases in adverse physical and behavioral health (BH) outcomes. CONCLUSIONS: Results indicate that burnout is a common problem across MHS Army staff and is related to significant adverse health consequences for the individual and reduced retention of staff for the organization. These findings highlight the need to address burnout through policies that standardize health care delivery policies and practices, providing support to leadership to promote a healthy workplace, and individual support to those who experience burnout.

Calibrating the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) for detecting alcohol-related problems among Canadian, UK and US soldiers: cross-sectional pre-deployment and post-deployment survey results.

OBJECTIVES: Excessive alcohol use can bring about adverse health and work-related consequences in civilian and military populations. Screening for excessive drinking can help identify individuals at risk for alcohol-related problems who may require clinical interventions. The brief validated measures of alcohol use such as the Alcohol Use Disorders Identification Test (AUDIT), or abbreviated AUDIT-Consumption (AUDIT-C), are often included in military deployment screening and epidemiologic surveys, but appropriate cut-points must be used to effectively identify individuals at risk. Although the conventional AUDIT-C cut-points ≥4 for men and ≥3 for women are commonly used, recent validation studies of veterans and civilians recommend higher cut-points to minimise misclassification and overestimation of alcohol-related problems. This study aims to ascertain optimal AUDIT-C cut-points for detecting alcohol-related problems among serving Canadian, UK and US soldiers. DESIGN: Cross-sectional pre/post-deployment survey data were used. SETTINGS: Comprised Army locations in Canada and UK, and selected US Army units. PARTICIPANTS: Included soldiers in each of the above-mentioned settings. OUTCOME MEASURES: Soldiers' AUDIT scores for hazardous and harmful alcohol use or high levels of alcohol problems served as a benchmark against which optimal sex-specific AUDIT-C cut-points were assessed. RESULTS: Across the three-nation samples, AUDIT-C cut-points of ≥6/7 for men and ≥5/6 for women performed well in detecting hazardous and harmful alcohol use and provided comparable prevalence estimates to AUDIT scores ≥8 for men and ≥7 for women. The AUDIT-C cut-point ≥8/9 for both men and women performed fair-to-good when benchmarked against AUDIT ≥16, although inflated AUDIT-C-derived prevalence estimates and low positive predictive values were observed. CONCLUSION: This multi-national study provides valuable information regarding appropriate AUDIT-C cut-points for detecting hazardous and harmful alcohol use, and high levels of alcohol problems among soldiers. Such information can be useful for population surveillance, pre-deployment/post-deployment screening of military personnel, and clinical practice.

Development of Training to Prepare Army Medics to Address Behavioral Health Needs of Soldiers in Far-Forward Environments Utilizing Mobile App Technology.

INTRODUCTION: Multi-domain operational combat environments will likely restrict key components of current behavioral health (BH) service delivery models. Combat teams in far-forward outposts or extended missions may need to rely on their own internal assets to manage combat and operational stress reactions for extended periods of time. As such, combat medics are expected to take on additional responsibilities as providers of BH support for isolated teams. As they receive limited BH training, medics require additional training to sufficiently respond to combat and operational stress reactions in their assigned teams. This study provided combat medics with a BH training and a mobile application-based support tool that would assist them in identifying and responding to BH concerns in their soldiers. The current analysis examines pre- to post-training changes in attitudes related to utilizing BH skills. MATERIALS AND METHODS: We created a brief training aimed to increase medics' ability and confidence regarding managing BH issues. Its development was part of a study on the feasibility of the Soldier and Medic Autonomous Connectivity Independent System for Remote Environments (AIRE) apps (NOCTEM, LLC), a digital system designed for far-forward BH and sleep monitoring and management. Participants were combat medics from two Army combat brigades preparing for a training rotation through a combat training center (CTC). A total of 16 medics consented to participation with nine medics available at the follow-up after the field exercise. Medics were surveyed before the training and after their return from the CTC. RESULTS: In pre-training surveys, most medics indicated it was within their scope to assess for stress/anxiety, suicidal risk, stress reaction, and sleep problems; assist soldiers with optimizing work performance; and provide interventions for BH concerns and sleep problems. Less than half believed it was within their scope to assess and address team communication issues or provide intervention for stress reactions. After the CTC rotation, more medics endorsed that it was in their scope to provide interventions for acute stress reactions to traumatic events. Before the CTC rotation, at most 60% of the group felt at least moderately confident in utilizing the BH skills of discussing problems, assessing for concerns, and providing interventions. After CTC, the confidence levels for each skill increased or remained the same for most medics. Intervention skills had the highest proportion of medics (66%) reporting increased confidence in using the skills. CONCLUSIONS: A larger proportion of medics believed it was within their scope of work and felt confident in assessing BH problems, and a smaller proportion believed it is within their scope of work and felt confident in applying interventions. The training increased most medics' confidence to administer interventions for BH and team communication issues. Similar training programs can help medics serve as support for a wide variety of circumstances when the brigade's mental health teams are inaccessible. Additionally, the Medic AIRE app expanded the ability to evaluate and provide interventions without extensive training in treatment modalities or BH conditions. This concept shows promise for providing medics with actionable tools when training time is limited such as during preparation for extended deployments.

Mild traumatic brain injury (concussion), posttraumatic stress disorder, and depression in U.S. soldiers involved in combat deployments: association with postdeployment symptoms.

OBJECTIVES: Several studies have examined the relationship between concussion/mild traumatic brain injury (mTBI), posttraumatic stress disorder (PTSD), depression, and postdeployment symptoms. These studies indicate that the multiple factors involved in postdeployment symptoms are not accounted for in the screening processes of the Department of Defense/Veteran's Affairs months after concussion injuries. This study examined the associations of single and multiple deployment-related mTBIs on postdeployment health. METHODS: A total of 1502 U.S. Army soldiers were administered anonymous surveys 4 to 6 months after returning from deployment to Iraq or Afghanistan assessing history of deployment-related concussions, current PTSD, depression, and presence of postdeployment physical and neurocognitive symptoms. RESULTS: Of these soldiers, 17% reported an mTBI during their previous deployment. Of these, 59% reported having more than one. After adjustment for PTSD, depression, and other factors, loss of consciousness was significantly associated with three postconcussive symptoms, including headaches (odds ratio [OR] = 1.5, 95% confidence interval [CI] = 1.1-2.3). However, these symptoms were more strongly associated with PTSD and depression than with a history of mTBI. Multiple mTBIs with loss of consciousness increased the risk of headache (OR = 4.0, 95% CI = 2.4-6.8) compared with a single occurrence, although depression (OR = 4.2, 95% CI = 2.6-6.8) remained as strong a predictor. CONCLUSIONS: These data indicate that current screening tools for mTBI being used by the Department of Defense/Veteran's Affairs do not optimally distinguish persistent postdeployment symptoms attributed to mTBI from other causes such as PTSD and depression. Accumulating evidence strongly supports the need for multidisciplinary collaborative care models of treatment in primary care to collectively address the full spectrum of postwar physical and neurocognitive health concerns.

The effects of mental health symptoms and organizational climate on intent to leave the military among combat veterans.

Frequent deployments to Iraq and Afghanistan have placed a strain on military retention. There is a need to determine contributing factors predicting intent to leave the military. The purpose of this study was to determine to what extent soldiers' mental health symptoms and perceptions of organizational climate are associated with intent to leave the military. Participants (n = 892) were soldiers of one infantry brigade combat team stationed in the United States, anonymously surveyed approximately 6 months after returning from a combat deployment to Iraq. The survey assessed overall deployment experiences, mental health symptoms, and perceptions of organizational climate. Results showed that soldiers reporting higher perceived organizational support were significantly less likely to report intent to leave and those screening positive for anxiety were significantly more likely to report intent to leave than those not screening positive. Implications of these results for Army clinicians and career counselors are discussed.

2003-2009 marital functioning trends among U.S. enlisted soldiers following combat deployments.

OBJECTIVE: This study examined 2003-2009 trends in three marital functioning indicators: marital quality, infidelity, and separation/divorce intent, and in marital dissolution rates among U.S. soldiers. METHODS: Marital functioning trends were examined with cross-sectional postdeployment sample data collected under the Land Combat Study from married, male, enlisted soldiers who had deployed to Iraq or Afghanistan (n = 5,928). Marital dissolution rates were examined with population data (n = 1,895,571). The relationships between time (measured by year) and all study variables were analyzed with chi2 tests of association, analysis of variance, and logistic regression analyses adjusting for combat exposure, mental and physical health, and demographic variables. RESULTS: Marital quality has declined, and reports of past-year infidelity and separation/divorce intent have increased between 2003 and 2009. However, no increases were observed in marital dissolution rates. CONCLUSIONS: The results indicate that more proximal indicators of marital functioning such as decreased marital quality, infidelity, and separation/divorce intent may better illustrate the strain that increased deployment tempo exerts on marital relationships. The findings provide a better understanding of how Army marriages have been affected by the wars, and suggest that further inquiry is needed on military marriages.

Far Forward Behavioral Health Service Delivery in Future Combat Environments: A Qualitative Needs Assessment.

INTRODUCTION: It is expected that future multi-domain operational (MDO) combat environments will be characterized by limited capabilities for immediate combat stress control support services for soldiers or immediate evacuation from theater. The operational requirements of the future battlefield make it unlikely that current models for behavioral health (BH) treatment could be implemented without significant adjustments. We conducted a qualitative study with Special Forces medics and operators and soldiers who had deployed to austere conditions in small groups in an effort to inform construction of a BH service delivery model for an MDO environment. The objectives of this study were (1) characterizing stressors and BH issues that were encountered and (2) describing mitigation strategies and resources that were useful or needed in these types of deployments. MATERIALS AND METHODS: Six focus groups were conducted at three army installations with 23 active duty soldiers, including three groups of medics using a semi-structured interview guide focused on stressors they encountered during deployments to austere conditions, and the impact of those stressors on mission and focus. Focus group recordings were transcribed, imported into NVivo software (version 12), and independently coded by two researchers. An analysis was then conducted to develop themes across participants. The study was reviewed by the Walter Reed Army Institute of Research Human Subjects Protection Board. RESULTS: Behavioral health concerns were commonly cited as a stressor in far forward environments. Other common stressors included ineffective or inexperienced leaders, as well as poor team dynamics (e.g., communication and cohesion). Four primary strategies were mentioned as mitigations for deployment stressors: leadership, morale, resilience training, and strength of the team. When asked about resources or training that would have helped with these types of deployments, participants frequently mentioned the availability of BH providers and development of new and realistic BH skills trainings for non-providers and leaders. CONCLUSIONS: Current models for treating BH problems need to be adapted for the future MDO environments in which soldiers will be expected to deploy. Understanding what issues need to be addressed in these environments and how they can best be delivered is an important first step. This study is the first to use qualitative results from those who have already deployed to such environments to describe the stressors and BH issues that were most commonly encountered, the mitigation strategies used, and the resources that were useful or needed.

Behavioral Health Provider Attitudes Toward Behavioral Health Profiles in the U.S. Army.

INTRODUCTION: U.S. Army healthcare providers' use of profiles to document and communicate behavioral health (BH) condition limitations to commanders is vital to understanding both the individual soldier's BH readiness for missions and, as an aggregate, the unit's overall BH readiness status. Quantitative work exploring the link between soldier attitudes toward BH profiles and treatment utilization found that profiles may actually promote increases in treatment-seeking behavior in those receiving conventional BH services. BH provider attitudes on the subject, however, have not been quantitatively explored. Using data from the recently described Behavioral Health Readiness and Decision-Making Instrument (B-REDI) study, the current inquiry addresses this by examining BH providers' pre-/post-B-REDI attitudes toward BH profiles, including therapeutic alliance, to better understand how BH profiles may impact BH treatment. METHODS: This study was approved by the WRAIR Institutional Review Board and is part of the larger B-REDI study. BH providers (n = 307) across five installations supporting active duty U.S. Army Divisions completed surveys longitudinally across three time points from September 2018 to March 2019. The survey specific to this study included five items, developed by WRAIR, assessing BH provider attitudes toward BH profiles. Of the providers who completed the survey, 250 (81%) consented to participate in the study and 149 (60%) completed the 3-month follow-up survey. RESULTS: Over 80% of BH providers expressed agreement with each of three items assessing rationale for issuing BH profiles in both the pre- and post B-REDI period. Specifically, most providers agreed that profiles facilitate commander support to the soldier, afford soldiers resources for recovery, and give commanders increased understanding of soldier health for mission planning. Twenty-six percent of BH providers agreed, 46% were neutral, and 28% disagreed on whether profile impact on the soldier was positive or not in the pre-B-REDI period, but there was a significant positive trend relative to baseline in the post B-REDI period. The vast majority of providers (≥94%) did not endorse agreement that BH profiles negatively impact therapeutic alliance in either the pre- or post-B-REDI period. CONCLUSIONS: Assuming that therapeutic alliance and perceptions of BH profile impact on soldiers are useful proxy measures of how treatment utilization may be affected by profiling, this inquiry fails to establish any meaningful negative association between them. This may provide some additional reassurance to BH providers and policymakers that efforts to improve readiness decision-making, such as B-REDI, and increased profiling in conventional military BH settings may not negatively impact treatment utilization rates.

Suicide Behavior Results From the U.S. Army's Suicide Prevention Leadership Tool Study: The Behavioral Health Readiness and Suicide Risk Reduction Review (R4).

INTRODUCTION: The U.S. Army developed a new tool called the Behavioral Health Readiness and Suicide Risk Reduction Review (R4) for suicide prevention. A 12-month evaluation study with the primary objective of testing the hypothesis (H1) that Army units receiving R4 would demonstrate improved outcomes in suicidal-behavior measures following the intervention, relative to control, was then conducted. The results of analyses to answer H1 are herein presented. MATERIALS AND METHODS: The R4 intervention (R4-tools/instructions/orientation) evaluation study, Institutional Review Board approved and conducted in May 2019-June 2020, drew samples from two U.S. Army divisions and employed a repeated measurement in pre-/post-quasi-experimental design, including a nonequivalent, but comparable, business-as-usual control. Intervention effectiveness was evaluated using self-report responses to suicide-related measures (Suicide Behaviors Questionnaire-Revised/total-suicide behaviors/ideations/plans/attempts/non-suicidal self-injuries) at 6-/12-month intervals. Analyses examined baseline to follow-up linked and cross-sectional cohorts, incidence/prevalence, and intervention higher-/lower-use R4 subanalyses. RESULTS: Both divisions demonstrated favorable in-study reductions in total-suicide burden, with relatively equivalent trends for total-suicide behaviors, total-suicide risk (Suicide Behaviors Questionnaire-Revised), suicidal ideations, and non-suicidal self-injuries. Although both demonstrated reductions in suicide plans, the control showed a more robust trend. Neither division demonstrated a significant reduction in suicide attempts, but subgroup analyses showed a significant reduction in pre-coronavirus disease 2019-attempt incidence among those with higher-use R4 relative to control. CONCLUSIONS: There is no evidence of harm associated with the R4 intervention. R4 effectiveness as a function of R4 itself requires confirmatory study. R4 is judged an improvement (no evidence of harm + weak evidence of effectiveness) over the status quo (no safety data or effectiveness studies) with regard to tool-based decision-making support for suicide prevention in the U.S. Army.

Interdisciplinary rehabilitation of mild TBI and PTSD: a case report.

BACKGROUND: Prevalence of mild traumatic brain injury (mTBI) or concussion on the battlefield in Iraq/Afghanistan has resulted in its designation as a 'signature injury'. Civilian studies have shown that negative expectations for recovery may lead to worse outcomes. While there is concern that concussion screening procedures in the Veteran's Affairs Healthcare System and the Department of Defence could fuel negative expectations, leading to negative iatrogenic effects, it has been difficult to document this in clinical settings. The aim of this report is to describe the case of a veteran with comorbid mTBI/PTSD with persistent symptoms of unknown aetiology and the effects of provider communications on the patient's recovery. METHODS: Case report of a veteran with reported mTBI, including provider communications, neuropsychological test results and report of functioning after changes in provider messages. RESULTS: Two-years post-mTBI, the patient attributed cognitive difficulties to his brain injury, but neuropsychological assessment found that his cognitive profile was consistent with psychological rather than neurological dysfunction. After providers systematically emphasized expectations of recovery, the patient's daily functioning improved. CONCLUSIONS: This case illustrates difficulties in mass screening for and treating mTBI. Recommendations for improvement include clinician training in effectively communicating positive expectations of recovery after concussion.

Results of the Behavioral Health Readiness Evaluation and Decision-Making Instrument Study.

INTRODUCTION: Recent reports have demonstrated behavioral health (BH) system and individual provider challenges to BH readiness success. These pose a risk to winning on the battlefield and present a significant safety issue for the Army. One of the most promising areas for achieving better BH readiness results lies in improving readiness decision-making support for BH providers. The Walter Reed Army Institute of Research (WRAIR) has taken the lead in addressing this challenge by developing and empirically testing such tools. The results of the Behavioral Health Readiness Evaluation and Decision-Making Instrument (B-REDI) field study are herein described. METHODS: The B-REDI study received WRAIR Institutional Review Board approval, and BH providers across five U.S. Army Forces Command installations completed surveys from September 2018 to March 2019. The B-REDI tools/training were disseminated to 307 providers through random clinic assignments. Of these, 250 (81%) providers consented to participate and 149 (60%) completed both initial and 3-month follow-up surveys. Survey items included a wide range of satisfaction, utilization, and proficiency-level outcome measures. Analyses included examinations of descriptive statistics, McNemar's tests pre-/post-B-REDI exposure, Z-tests with subgroup populations, and chi-square tests with demographic comparisons. RESULTS: The B-REDI resulted in broad, statistically significant improvements across the measured range of provider proficiency-level outcomes. Net gains in each domain ranged from 16.5% to 22.9% for knowledge/awareness (P = .000), from 11.1% to 15.8% for personal confidence (P = .001-.000), and from 6.2% to 15.1% for decision-making/documentation (P = .035-.002) 3 months following B-REDI initiation, and only one (knowledge) failed to maintain a statistically significant improvement in all of its subcategories. The B-REDI also received high favorability ratings (79%-97% positive) across a wide array of end-user satisfaction measures. CONCLUSIONS: The B-REDI directly addresses several critical Army BH readiness challenges by providing tangible decision-making support solutions for BH providers. Providers reported high degrees of end-user B-REDI satisfaction and significant improvements in all measured provider proficiency-level domains. By effectively addressing the readiness decision-making challenges Army BH providers encounter, B-REDI provides the Army BH health care system with a successful blueprint to set the conditions necessary for providers to make more accurate and timely readiness determinations. This may ultimately reduce safety and mission failure risks enterprise-wide, and policymakers should consider formalizing and integrating the B-REDI model into current Army BH practice.

Methodology of the U.S. Army's Suicide Prevention Leadership Tool Study: The Behavioral Health Readiness and Suicide Risk Reduction Review (R4).

INTRODUCTION: The Secretary of the U.S. Army issued two directives in late 2017 to directly combat the problem of suicide in the U.S. Army. The first was to develop an Army tool to assist commanders and first-line leaders in preventing suicide and improving behavioral health (BH) outcomes, which has been previously published as the BH Readiness and Risk Reduction Review (R4). The second was to conduct an evaluation study of the tool with Army units in the field. This study is the first to empirically examine the Army's tool-based methods for identifying and caring for the health and welfare of soldiers at risk for suicide, and this article outlines the methodology employed to study the effectiveness of the R4 tools and accomplish the Secretary's second directive. METHODS: The Walter Reed Army Institute of Research Institutional Review Board approved the R4 study. The study employed a repeated measurements in pre/post quasi-experimental design, including a nonequivalent but comparable business-as-usual control group. The R4 intervention consisted of the R4 tools, accompanying instructions, and an orientation. Samples were drawn from two geographically separated U.S. Army divisions in the continental United States, each composed of four comparable brigades. Study implementation consisted of three phases and three data collections over the course of 12 months. Soldiers completed anonymous survey instruments to assess a range of health factors, behaviors, characteristics, tool-related decision-making processes, and the frequency, type, and quality of interactions between soldiers and leaders. RESULTS: The R4 study commenced on May 6, 2019, and concluded on June 4, 2020. Sample size goals were achieved for both the divisions at all three data collection time points. CONCLUSIONS: The methodology of the R4 study is critical for the U.S. Army from both a precedential and an outcome-based standpoint. Despite the use of many previous tools and programs for suicide prevention, this is the first time the Army has been able to empirically test the effectiveness of tool-supported decision-making among Army units in a rigorous fashion. The methodology of such a test is a critical marker for future interventional inquiries on the subject of suicide in the Army, and the results will allow for more informed decision-making by leaders when approaching these ongoing challenges.

Mild traumatic brain injury (concussion) during combat: lack of association of blast mechanism with persistent postconcussive symptoms.

OBJECTIVE: To determine whether screening for a blast mechanism of concussion identifies individuals at higher risk of persistent postconcussive symptoms (PCS). SETTING: United States Army post. PARTICIPANTS: 3952 US Army infantry soldiers were administered anonymous surveys 3 to 6 months after returning from a yearlong deployment to Iraq. MAIN OUTCOME MEASURES: Self-reported concussion (defined as an injury that resulted in being "dazed, confused, or 'seeing stars'"; "not remembering the injury"; or "losing consciousness [knocked out]): Patient Health Questionnaire 15-item scale for physical symptoms and PCS; Posttraumatic Stress Disorder Checklist; and Patient Health Questionnaire depression module. RESULTS: Of the 587 soldiers (14.9% of the total sample) who met criteria for concussion, 201 (34.2%) reported loss of consciousness, and 373 (63.5%) reported only an alteration of consciousness without loss of consciousness; 424 (72.2%) reported a blast mechanism, and 150 (25.6%) reported a nonblast mechanism. Among soldiers who lost consciousness, blast mechanism was significantly associated with headaches and tinnitus 3 to 6 months postdeployment compared with a nonblast mechanism. However, among the larger group of soldiers reporting concussions without loss of consciousness, blast was not associated with adverse health outcomes. CONCLUSIONS: Blast mechanism of concussion was inconsistently associated with PCS, depending on the definition of concussion utilized. A self-reported history of blast mechanism was not associated with persistent PCS for the majority of US soldiers with concussions.

Mental Health Service Utilization and Perceived Barriers to Receiving Care in Deployed Soldiers.

INTRODUCTION: Scant research has examined mental health treatment utilization and barriers to care in deployed U.S. soldiers. This study aims to assess mental health treatment utilization in deployed soldiers, including providers used and barriers to care. MATERIALS AND METHODS: U.S. Army soldiers (n = 2,412) in a combat environment were surveyed on psychiatric symptoms, mental health help received, sources of care, and perceived barriers to care by Mental Health Advisory teams from 2009 to 2013. RESULTS: Of the 25% of soldiers at mental health risk, 37% received mental health help, with 18% receiving help from a provider. Nonprovider sources of care were utilized significantly more frequently than providers. Soldiers at mental health risk reported significantly greater anticipated career-related stigma, organizational barriers to care, self-reliance views, and negative attitudes toward care, yet these constructs did not differ between who did or did not receive help. Soldiers who received help from providers exclusively reported significantly more anticipated career-related stigma and fewer organizational barriers to care than those that received no help. Soldiers who spent no time living outside the forward operating base and soldiers with six or more types of combat exposures were more likely to receive help. CONCLUSIONS: Prevalence of common psychopathology and receipt of care in a combat environment was similar to previous reports from postdeployment settings. Nonprovider sources of care were more frequently utilized as compared to an in-Garrison report. Findings suggest important differences exist in sources of help and barriers to care in deployed vs. postdeployment environments. The hypothesized barriers to care did not preclude receiving any help, however, less than one-half of soldiers at mental health risk received help. Thus, future research should identify factors that have the greatest influence on help seeking behavior in both deployed and Garrison settings.
