Longitudinal measurement invariance and growth curve modeling of psychological resilience across the deployment cycle.

The concept of resilience is embedded within military culture and professional identity. To date, temporal changes in individuals' perceptions of their own resilience have not been systematically assessed in highstakes occupational contexts, like the military. The current study examined change in selfreported resilience over time by: (1) examining the longitudinal measurement invariance of the Brief Resilience Scale (BRS); (2) assessing the longitudinal pattern of resilience across a combat deployment cycle; and (3) examining predictors of postdeployment resilience and change in resilience scores across time. U.S. Army soldiers assigned to a combat brigade completed a survey at four time points over the course of a deployment cycle: (a) prior to deployment to Afghanistan; (b) during deployment; (c) immediately following return to home station; and (d) approximately 2-3 months thereafter. The longitudinal measurement invariance of the BRS was established. Growth curve modeling indicated that, on average, self-reported resilience decreased across the deployment cycle, but there was considerable individual variation in the rate of change. Of note, loneliness, as measured during deployment, predicted the rate of change in self-reported resilience over time. Results have implications for the longitudinal analysis of resilience and for the development of interventions with military personnel.

Insufficient Sleep and Behavioral Health in the Military: A 5-Country Perspective.

PURPOSE OF REVIEW: The goal of this paper was to highlight the degree to which sleep, behavioral health, and leader involvement were interrelated using data from militaries in five English-speaking countries: Australia, Canada, New Zealand, the UK, and the United States. RECENT FINDINGS: Many service members reported sleeping fewer than the recommended 7 h/night: 34.9%, 67.2%, and 77.2% of respondents from New Zealand, Canada, and the United States, respectively. Countries reporting shorter sleep duration also reported fewer insomnia-related difficulties, likely reflecting higher sleep pressure from chronic sleep loss. Across all countries, sleep problems were positively correlated with behavioral health symptoms. Importantly, leader promotion of healthy sleep was positively correlated with more sleep and negatively correlated with sleep problems and behavioral health symptoms. Insufficient sleep in the military is ubiquitous, with serious implications for the behavioral health and functioning of service members. Leaders should attend to these risks and examine ways to promote healthy sleep in service members.

Types of COVID-19 Disaster Work and Psychological Responses in National Guard Service Members.

INTRODUCTION: The National Guard (NG) served as a critical component of the U.S. response to the coronavirus disease 2019 pandemic. Understanding the impact of types of pandemic-related disaster work on mental health responses can aid in sustaining NG service members' health and preparation for subsequent activations and future pandemics. MATERIALS AND METHODS: We surveyed 1,363 NG unit (NGU) service members (88% Army; 80% enlisted; 32% 30 to 39 years old; 84% male) following activation in response to the pandemic. Surveys were administered between August and December 2020, which was approximately 2 to 3 months post-activation. Surveys assessed overall activation stress, participation in different types of disaster work, probable post-traumatic stress disorder (PTSD), anxiety and depression, and anger. A disaster work stress scale assessed different types of disaster work during activation and associated stress levels. For each individual, we calculated an overall work task stress (WTS) scaled score, with a maximum score of 100. Logistic regression analyses were conducted to examine the relationship of high-stress disaster work tasks to post-activation PTSD, anxiety and depression, and anger, adjusting for socio-demographic and service-related variables. The study was approved by the Institutional Review Board of the Uniformed Services University (USU) in Bethesda, MD. RESULTS: Among NGU service members, 12.7% (n = 172) described their activation as very/extremely stressful. The work tasks with the highest scaled scores were as follows: (1) Patient transportation (WTS scaled score = 100); (2) working with the dead (WTS = 82.2); and (3) working with families of coronavirus disease 2019 patients (WTS = 72.7). For each individual's work tasks, we identified the work task associated with the highest WTS score. The top one-third of WTS scores were classified as the high-stress group. Approximately 9% of participants (n = 111) had probable PTSD, 6.7% (n = 85) had clinically significant anxiety and depression, and 12.3% (n = 156) had high anger. Multivariable logistic regression analyses, adjusting for covariates, found that NGU service members exposed to the highest level of disaster WTS were more likely to report PTSD (odds ratio [OR] = 1.48 [95% confidence interval [CI] = 1.13-1.94], χ2 = 7.98), anxiety and depression (OR = 1.91 [95% CI = 1.17-3.13]; χ2 = 6.67), and anger (OR = 1.63 [95% CI = 1.13-2.37]; χ2 = 6.66) post-activation. CONCLUSIONS: Identifying work tasks associated with high levels of stress can help detect individuals at risk for adverse mental health responses post-exposure. Distinguishing features of high-stress work conditions can be generalized to other types of work conditions and disaster response and are important targets for planning and preventive efforts.

Three-Item Dimensions of Anger Reactions Scale.

Importance: Problematic anger is prevalent and associated with adjustment difficulties in military populations. To facilitate measurement of problematic anger, a very brief valid measure is needed. Objective: To reduce the Dimensions of Anger Reactions 5-item (DAR-5) scale to a very brief measure. Design, Setting, and Participants: This cross-sectional study used survey data collected between 2014 and 2016 in the Australian Transition and Well-Being Research Programme and US Millennium Cohort Study. Participants were service members who were actively serving or had transitioned out of the military (separated). Statistical analyses were performed from September 2021 to June 2023. Main Outcomes and Measures: The DAR-5 was reduced to the 3 experiential items: frequency, intensity, and duration (the DAR-3). Psychometrics for the DAR-3 and DAR-5 were compared in terms of standardized Cronbach α, positive screening result, mean, and SD. Analyses were stratified by Australian and US military service status cohorts (active duty and separated). Results: A total of 71 010 participants were included from Australia and the US. Of 10 900 Australian participants (8145 active duty participants [74.7%]; 2755 separated participants [25.3%]), 5893 (55.2%) were aged 40 years or older and 8774 (80.5%) were male; of 60 110 US participants (24 706 active duty participants [41.1%]; 35 404 separated participants [58.9%]), 28 804 (47.9%) were aged 30 to 39 years and 43 475 (72.3%) were male. The DAR-3 demonstrated good internal consistency in the active duty (Australia: mean [SD] score, 4.97 [2.5]; α = 0.90; US: mean [SD] score, 5.04 [2.6]; α = 0.87) and separated (Australia: mean [SD] score, 6.53 [3.4]; α = 0.92; US: mean [SD] score, 6.05 [3.2]; α = 0.91) samples. The cutoff score of 8 or greater on the DAR-3 had optimal sensitivity and specificity across all samples. DAR-3 and DAR-5 were associated with posttraumatic stress disorder (PTSD), depression, aggression, and relationship conflict. While the scales did not significantly differ in their associations with PTSD, depression, and relationship conflict, the magnitude of association for aggression was significantly lower in US samples using the DAR-3 (eg, US active duty sample: DAR-5 OR, 9.96; 95% CI, 9.01-11.00; DAR-3 OR, 8.36; 95% CI, 7.58-9.22). Conclusions and Relevance: In this cross-sectional study of a very brief measure of anger, each item contributed to the overall strength of the measure without losing psychometric strength compared with the DAR-5. The consistency of these findings across military and veteran samples in Australian and US populations demonstrated the psychometric robustness of the DAR-3.

COVID-19 Concerns, Information Needs, and Adverse Mental Health Outcomes among U.S. Soldiers.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic disrupted U.S. Military operations and potentially compounded the risk for adverse mental health outcomes by layering unique occupational stress on top of general restrictions, fears, and concerns. The objective of the current study was to characterize the prevalence of COVID-19 concerns and information needs, demographic disparities in these outcomes, and the degree to which COVID-19 concerns and information needs were associated with heightened risk for adverse mental health outcomes among U.S. Army soldiers. MATERIALS AND METHODS: Command-directed anonymous surveys were administered electronically to U.S. soldiers assigned to one of three regional commands in the Northwest United States, Europe, and Asia-Pacific Region. Surveys were administered in May to June 2020 to complete (time 1: n = 21,294) and again in December 2020 to January 2021 (time 2: n = 10,861). Only active duty or active reservists/national guard were eligible to participate. Members from other branches of service were also not eligible. RESULTS: Highly prevalent COVID-19 concerns included the inability to spend time with friends/family, social activities, and changing rules, regulations, and guidance related to COVID-19. Some information needs were endorsed by one quarter or more soldiers at both time points, including stress management/coping, travel, how to protect oneself, and maintaining mission readiness. COVID-19 concerns and information needs were most prevalent among non-White soldiers. Concerns and information needs did not decline overall between the assessments. Finally, COVID-19 concerns were associated with greater risk of multiple adverse mental health outcomes at both time points. CONCLUSIONS: COVID-19 concerns and information needs were prevalent and showed little evidence of decrement over the course of the first 6 months of the pandemic. COVID-19 concerns were consistently associated with adverse mental health outcomes. These data highlight two targets and potential demographic subgroups such that local leadership and Army medicine and public health enterprises can be better prepared to monitor and address to maintain force health and readiness in the face of possible future biomedical threats.

National Guard Deployment in Support of COVID-19: Psychological and Behavioral Health.

INTRODUCTION: The National Guard (NG) served as a critical component of the USA's response to the Coronavirus Disease 2019 (COVID-19) pandemic, while concurrently managing their personal responses to the pandemic. Determining whether the activation of NG service members in response to the COVID-19 pandemic was associated with a greater psychological strain can identify NG's needs for mental health support. MATERIALS AND METHODS: We surveyed 3993 NG unit (NGU) service members (75% Army NG, 79% enlisted, 52% 30-49 years old, and 81% males) during the COVID-19 pandemic, with surveys administered between August and November 2020. Almost half (46%) of NGU service members reported being activated in response to COVID-19 (mean activation length = 18.6 weeks). Activated service members completed the survey approximately 2 to 3 months post-activation. Surveys assessed demographics, service-related characteristics, unit cohesion and positive leadership skills (leadership), and COVID-19 activation, and outcomes including probable post-traumatic stress disorder (PTSD), clinically significant anxiety and depression, and anger. Descriptive and logistic regression analyses were conducted. The study was approved by the Institutional Review Board of the Uniformed Services University of the Health Sciences in Bethesda, MD. RESULTS: In all, 9.7% met the criteria for probable PTSD, 7.6% reported clinically significant anxiety and depression, and 13.2% reported feeling angry/anger outbursts. Multivariate logistic regression analyses, adjusting for demographic and service-related characteristics, indicated that COVID-19 activation was not associated with a greater risk of PTSD, anxiety and depression, or anger. Regardless of activation status, NGU service members with low levels of unit cohesion and leadership were more likely to report PTSD and anger, and low levels of unit cohesion were associated with clinically significant anxiety and depression. CONCLUSIONS: COVID-19 activation did not increase the risk of mental health difficulties among NGU service members. However, low levels of unit cohesion were associated with the risk of PTSD, anxiety and depression, and anger, and low levels of leadership were associated with the risk of PTSD and anger. The results suggest a resilient psychological response to COVID-19 activation and the potential for strengthening all NG service members through enhancing unit cohesion and leadership support. Future research on specific activation exposures, including the type of work tasks in which service members are engaged, particularly those associated with high-stress work conditions, is needed to help better understand their activation experience and how it may influence post-activation responses.

Impact of mindfulness training and yoga on injury and pain-related impairment: a group randomized trial in basic combat training.

Introduction: Service members are at risk for pain-related difficulties in functioning and physical injury. Previous studies suggest that mindfulness training (MT) and yoga may prevent these outcomes. The present study was designed to determine the impact of MT and yoga on the health, pain, and injury of Army trainees completing 10 weeks of basic combat training (BCT). Methods: Platoons (≈40 trainees per platoon) were randomized to MT and yoga or training-as-usual in October to December 2020 at a large installation in the US. Self-reported outcomes were health, pain level, and pain impact on training, sleep, mood, and stress. Objective outcomes were injury-related medical encounters and number of diagnoses. The trial was registered at ClinicalTrials. Gov (NCT05550610). Results: Intervention trainees reported significantly better health (OR = 1.05, 95% CI [1.00, 1.10]) and less impact of pain on training (OR = 0.81, 95% CI [0.74, 0.90]), sleep (OR = 0.88, 95% CI [0.81, 0.95]), mood (OR = 0.86, 95% CI [0.78, 0.96]), and stress (OR = 0.88, 95% CI [0.79, 0.98]). There was no significant difference in injury-related medical encounters (AOR = 0.70, 95% CI [0.48, 1.03]), but intervention trainees had fewer diagnoses (OR = 0.67, 95% CI [0.47, 0.95]) and were 30% less likely to have a first medical encounter at any time during BCT. This difference emerged 3 weeks into BCT. Discussion: A combined MT and yoga intervention resulted in better trainee health. The US Army and other organizations requiring resilience under extreme stress should consider implementing MT and yoga to offset risks to employee health.

Impact of the COVID-19 pandemic on army families: Household finances, familial experiences, and soldiers' behavioral health.

The Coronavirus Disease 2019 (COVID-19) pandemic has significantly impacted employment and finances, childcare, and behavioral health across the United States. The Behavioral Health Advisory Team assessed the pandemic's impact on the behavioral health of U.S. Army soldiers and their families. Over 20,000 soldiers at three large installation groups headquartered in the northwestern continental U.S., Republic of Korea, and Germany participated in the cross-sectional survey. Multivariable logistic regression models indicated that key demographics (gender, rank), severity of household financial impact, changes in work situation due to childcare issues, and family members' difficulty coping (both self and spouse/partner and/or child) were independently and consistently associated with greater odds of screening positive for probable clinical depression and generalized anxiety, respectively. These findings highlight how Army families were impacted similarly by the pandemic as their civilian counterparts. Army leadership may action these findings with targeted support for soldiers and their families to ensure they are utilizing supportive services available to them, and that military services continually evolve to meet soldier and family needs during times of crisis and beyond.

Leadership in moral awareness: Initial evidence from U.S. Army soldiers returning from deployment.

OBJECTIVE: To determine whether moral awareness leadership moderated the relationship between combat experiences and soldier mental health symptoms following deployment. METHOD: The Leadership in Moral Awareness Scale (LIMAS) was evaluated using anonymous surveys completed by 177 U.S. Army National Guardsmen. The survey also assessed general leadership, combat experiences, and posttraumatic stress disorder (PTSD), anxiety, and depression symptoms. Following factor analyses of the LIMAS, moderated regression models examined interactions between the LIMAS and combat experiences on mental health symptoms. RESULTS: Six items were selected to comprise the LIMAS. No main effect of the LIMAS was found for mental health variables after adjusting for general leadership. There were significant interaction effects between the LIMAS and combat experiences for depression and anxiety symptoms. Soldiers with higher levels of combat experiences reported fewer mental health symptoms if their leaders were rated highly on the LIMAS. CONCLUSIONS: The LIMAS may offer a useful tool for assessing leader behaviors that can counteract negative mental health outcomes associated with combat. Findings provide support for encouraging leaders to focus on moral awareness during deployment. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Wellness checks: Piloting a universal intervention for soldiers.

As part of an Army pilot program, mandatory annual wellness checks were initiated to introduce individuals to counseling and to support psychological resilience and thriving. The program was evaluated using a cross-sectional survey completed by 7,831 soldiers. Findings revealed that about half of soldiers who reported a wellness check rated the check at least moderately helpful in their professional and personal lives. Participants receiving a wellness check reported being more likely to report willingness to seek help if they were to have mental health problems and to report higher levels of resilience and thriving even after controlling for rank, age, education, months in the unit, and trait negative affect. Participants were also less likely to report stigma-related concerns compared to those who had not received a wellness check. Consistent with theory on the common factors in counseling and the contextual model of psychotherapy (Laska et al., 2014), feeling listened to and learning new skills partially mediated the association between perceived wellness check usefulness and study outcomes, although acquiring a new perspective about problems did not. While not a randomized trial, this evaluation suggests that wellness checks are associated with programmatic goals: improved attitudes toward care seeking, resilience, and thriving. Future work should consider ways to ensure counselors address therapeutic common factors and should use a randomized, longitudinal design. Study findings have implications for implementing programs like wellness checks for military personnel and others working in high-stress occupations like first responders.

Peer-based intervention for acute stress reaction: adaptations by five militaries.

Military service members need to be able to operate under conditions of extreme stress to ensure the success of their team's mission; however, an acute stress reaction (ASR) can compromise team safety and effectiveness by rendering an individual unable to function. Building on an intervention originally developed by the Israel Defense Forces, several countries have developed, tested, and disseminated a peer-based intervention to help service members manage acute stress in others. This paper reviews how five countries (Canada, Germany, Norway, the UK and the USA) adjusted the protocol to fit their organisational culture while retaining essential elements of the original procedure, suggesting there can be interoperability and mutual intelligibility in the management of ASR by military allies. Future research should examine the parameters of effectiveness for this intervention, the impact of intervention on long-term trajectories, and individual differences in managing ASR.

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.

Optimizing Performance and Mental Skills With Mindfulness-Based Attention Training: Two Field Studies With Operational Units.

INTRODUCTION: Mental skills such as focusing attention and managing emotions are essential for optimal performance in high-stress occupations. Studies with military samples have demonstrated that mindfulness training (MT) led to improved computer-based cognitive performance. MATERIALS AND METHODS: To examine the impact of MT on operational performance, mental skills, and psychological health, a short-form program, Mindfulness-Based Attention Training (MBAT), was delivered to active duty soldiers as part of two randomized trials. Participants in study 1 (n = 121) and study 2 (n = 77) were randomized to one of three conditions: MT with proctored practice, MT with unproctored practice, or a waitlist control. Weekly 2-hour MBAT sessions were offered to participants in both MT conditions for 4 weeks. Beyond these sessions, participants also engaged in mindfulness practice that was proctored (within the occupational context) or unproctored (left up to the individual) for four subsequent weeks. RESULTS: Overall, the frequency of mindfulness practice was generally associated with better performance and improvements in mental skills. In study 1, those who practiced 3 or more days per week performed better on marksmanship under physical stress and reported fewer attentional lapses, less emotion regulation difficulties, greater mental toughness, and higher self-reported mindfulness compared to those who did not practice. In study 2, the frequency of mindfulness practice was associated with fewer attentional lapses and emotion regulation difficulties. CONCLUSIONS: Consistent with prior findings, results suggest that regular engagement in MT practice may help to optimize operational performance and improve mental skills in military cohorts.

Management of Acute Stress Reactions in the Military: A Stepped Care Approach.

PURPOSE OF THE REVIEW: This review highlights knowledge gaps surrounding the development and use of interventions for Acute Stress Reactions (ASRs). First, we propose that a stepped care approach to intervention for ASR be developed and utilized in military operational environments. A stepped care approach would include detection and assessment, followed by behavioral intervention, and then medication intervention for ASRs. Second, we discuss potential strategies that can be taken for the development of safe and effective ASR medications. RECENT FINDINGS: ASRs commonly occur in operational environments, particularly in military populations. ASRs impact the safety and performance of individual service members and teams, but there are currently limited options for intervention. Efforts to improve ASR detection and assessment, and development and delivery of ASR interventions for implementation in operational environments, will be critical to maintaining the safety and performance of service members.

Problematic Anger in the Military: Focusing on the Forgotten Emotion.

PURPOSE OF REVIEW: Problematic anger is common in veteran and military populations, yet understudied relative to other mental health difficulties. However, in recent years, more clinical and research attention has been turned to problematic anger. This paper highlights important new findings in the epidemiology, course, and neurobiology of anger, the associations of anger with other mental health problems and risk, and next steps for research and practice. RECENT FINDINGS: In longitudinal research, findings show that problematic anger changes over the life course of military members and veterans, and that deployment increases the likelihood of problematic levels of anger. Problematic anger is related to a range of mental health issues, most perniciously aggression and suicidality. Promising new assessment and treatment approaches are emerging, including innovations that leverage digital technology. Key areas of research include advancing assessment of problematic anger to identify patterns of heterogeneity, as well as advancing the evidence base for anger treatments. Recommended progress in clinical practice include conducting routine assessment of problematic anger in veteran and military populations, developing prevention and early intervention for at risk individuals, and optimizing the timing of interventions throughout the military lifecycle.

Association of Problematic Anger With Long-term Adjustment Following the Military-to-Civilian Transition.

Importance: Few studies have examined the role of problematic anger in long-term adjustment of service members transitioning out of the military. Objective: To determine the prevalence of problematic anger during the military-to-civilian transition period and the association of problematic anger with adjustment to civilian life. Design, Setting, and Participants: This cohort study used 2 waves of survey data administered approximately 5 years apart (time 1 [T1; September 26, 2014, to August 25, 2016] and time 2 [T2; October 23, 2019, to August 31, 2021]) from the Millennium Cohort Study, a population-based military study. Participants were US active-duty service members within 24 months of separating from military service at T1. Statistical analysis was performed from September 2021 to May 2022. Exposures: Problematic anger was operationalized as scoring at least 12 points on the 5-item Dimensions of Anger Reactions scale at T1. Main Outcomes and Measures: Behavioral and functional health (depression, posttraumatic stress disorder, problem drinking, functional limitations), relationship health (relationship quality, coping with parental demands, social support), and economic health (major financial problems, financial insecurity, homelessness, employment status) were assessed at T2. Covariates, assessed at T1, included demographics, military characteristics, mental health, problem drinking, and physical health. Results: Of the 3448 participants, 2625 (76.1%) were male, 217 (6.3%) were Hispanic, 293 (8.5%) were non-Hispanic Black, and 2690 (78.0%) were non-Hispanic White; the mean (SD) age was 40.1 (8.5) years; 826 (24.0%) met criteria for problematic anger. Prevalence of problematic anger was 15.9% (95% CI, 12.2%-19.7%) 24 months prior to military separation and 31.2% (95% CI, 26.2%-36.2%) 24 months following separation. After adjusting for covariates, problematic anger was associated with greater likelihood of behavioral and functional health outcomes (eg, posttraumatic stress disorder: adjusted odds ratio, 1.55, 95% CI, 1.23-1.96), relationship health difficulties (eg, low social support: aOR, 1.66; 95% CI, 1.23-2.24), and economic difficulties (eg, substantial financial insecurity: aOR, 1.64; 95% CI, 1.13-2.39) at T2. Conclusions and Relevance: This cohort study found an association between prevalence of problematic anger during the military-to-civilian transition and problematic anger with subsequent adjustment difficulties among US service members. These findings suggest the need to equip service members proactively with skills to identify and manage anger as a way to support them before and during this period of transition.

Combat exposure and behavioral health in U.S. Army Special Forces.

Although combat has been found to be associated with adverse health outcomes, little is known about the impact of specific combat exposures, particularly among specialized personnel. This study examined the association of different types of combat exposures with behavioral health outcomes, and whether these associations differed by Army occupational specialization: General Purpose Forces infantrymen (n = 5,361), Ranger Qualified infantrymen (n = 308), and Special Forces personnel (n = 593). Multivariable regression models estimated the association of combat severity, type of combat event (fighting, killing, threat to oneself, death/injury of others), and type of killing with mental health disorders, trouble sleeping, and problem drinking. Combat severity, each type of combat event, and killing noncombatants were associated with adverse health outcomes after adjusting for covariates and other combat exposures. Except for trouble sleeping, these associations did not differ by occupational specialization, though the prevalence and odds of outcomes were generally lower for Special Forces personnel.

US soldiers and the role of leadership: COVID-19, mental health, and adherence to public health guidelines.

BACKGROUND: Previous studies have documented the impact of domain-specific leadership behaviors on targeted health outcomes in employees. The goal of the present study was to determine the association between specific leadership behaviors addressing COVID-19 and US soldiers' mental health and adherence to COVID-19 public health guidelines. METHODS: An electronic, anonymous survey was administered to US Army soldiers across three major commands (N = 7,829) from December 2020 to January 2021. The primary predictor of interest was soldiers' ratings of their immediate supervisors' behaviors related to COVID-19. The outcomes were soldiers' mental health (i.e., depression and generalized anxiety) and adherence to COVID-19 public health guidelines. Covariates were rank, gender, ratings of immediate supervisors' general leadership, level of COVID-19 concerns, and COVID-19 status (e.g., tested positive, became seriously ill). Logistic regressions were used to model the unique association of COVID-19 leadership behaviors with outcomes after adjusting for covariates. RESULTS: High levels of COVID-19 leadership behaviors were associated with lesser likelihood of soldiers' screening positive for depression (AOR = 0.46; 95% CI [0.39, 0.54]) and anxiety (AOR = 0.54; 95% CI [0.45, 0.64]), and greater likelihood of frequent adherence to preventive health guidelines (AORs = 1.58; 95% CI [1.39, 1.80] to 2.50; 95% CI [2.01, 3.11]). CONCLUSION: Higher levels of COVID-19 leadership behaviors may support soldiers' mental health and encourage their adherence to COVID-19 public health guidelines. Given the link between these leader behaviors and soldier adaptation to the pandemic over and above general leadership, training for supervisors should focus on targeting specific health-promoting behaviors. Results can inform leader training for the military and other high-risk occupations.
