A Call to Validate the Stress Continuum Model.

INTRODUCTION: Since the start of the Global War on Terrorism, exponential demands have been put on military personnel, their families, and the military health care system. In response to a Department of Defense Task Force on Mental Health, the U.S. military began developing and fielding programs to promote the psychological health of its personnel. As part of these initiatives, the Navy and Marine Corps developed the Stress Continuum model. The Stress Continuum is a stress classification system ("ready," "reacting," "injured," and "ill") that provides a common language for identifying, engaging, and intervening when stress reactions or stress injuries are present in military personnel. It is the foundation for resilience and prevention efforts across the Navy and Marine Corps. Although the Stress Continuum has strong face validity, is consistent with current theory, and has been agreed up by expert consensus, it has yet to be empirically validated. The goal of the current article is to begin to empirically validate the Stress Continuum using validated measures of psychological stress. MATERIALS AND METHODS: We conducted a retrospective analysis of Stress Continuum data (n = 2,049) collected as part of a program evaluation of two Navy operational stress control programs. Receiver operating characteristic (ROC) curves and analyses were conducted to determine the classification quality of the Stress Continuum using a validated measure of stress (a brief version of the Perceived Stress Scale [PSS-4]). RESULTS: For the first ROC curve, we used the "ill" category (vs. the other three categories) to identify the cut point on the PSS-4. PSS-4 cut point values of 9 and 10, respectively, maximized sensitivity and 1-specificity values. Using the chi-square test, we further found that a more accurate prediction for those in the "ill" category was using the cut point of 9 (79%) relative to 10 (71.8%). For the second and the third ROC curves, we used the "ill" and "injured" categories (vs. the other two categories) and "ill," "injured," and "reacting" categories (vs. the "ready" category), respectively. No optimal cut points on the PSS-4 were identified for these models, indicating that the PSS-4 could not reliably differentiate true-positive and false-positive rates. CONCLUSIONS: We found that the "ill" category of the Stress Continuum was predictive of higher levels of stress on the validated measure of perceived stress. Thus, our findings strongly suggest that the individuals in the "ill" zone likely warrant some type of intervention by a trained professional. FUTURE RESEARCH: The Navy has recently leveraged the Stress Continuum to create the Stress-o-Meter to support the fundamental principles of early recognition, peer intervention, and connection to services at the unit level. The Stress-o-Meter serves as a prevention tool that has the capability to collect information about stress levels throughout the entire unit at any time. Continued work on validating the Stress Continuum model and making it easily accessible to military units will ensure service members get the support they need and leaders are able to address the psychological health of their units.

Promoting resilience and psychological wellbeing of military providers: The Navy Medicine Caregiver Occupational Stress Control (CgOSC) program.

Military Medicine providers (sometimes referred to as caregivers) not only endure the stress of supporting the medical readiness of operational commands, they take on the continuous demands involved in providing direct care to military beneficiaries. Research shows that occupational stress and burnout impacts the health and wellbeing of providers, increases job turnover, and reduces the quality of patient care. Thus, interventions have aimed to reduce burnout and enhance the wellbeing of military providers. Although these efforts have shown promise, there is much room for improvement. Navy Medicine has implemented the Caregiver Occupational Stress Control (CgOSC) program at its commands, with the objectives to enhance provider wellbeing and resilience, improve retention, and ensure the quality of patient care. This article introduces the Navy Medicine CgOSC program, describes the implementation of the CgOSC program at Navy Medicine commands, and delineates how the program is tracked for program adherence. This tracking method can serve as a model for other healthcare organizations that are establishing programs that aim to promote the wellbeing of their providers.

Post-Traumatic Stress Disorder Treatment Outcomes in Military Clinics.

INTRODUCTION: Despite a wide literature describing the impact of PTSD on military personnel, there is limited information concerning the results of PTSD treatment within military clinics mental health. Having such information is essential for making predictions about service members' chances of recovery, choosing best treatments, and for understanding if new interventions improve upon the standard of care. MATERIALS AND METHODS: We reviewed data from the Psychological Health Pathways (PHP) database. Psychological Health Pathways is a standardized battery of demographics and psychometric outcome measures, including measurement of PTSD symptom severity, that is collected in military mental health clinics. We examined changes in PTSD symptom severity scores over time and developed logistic regression models to predict who responded to treatment, showed clinical success, or improved to the point that they could likely stay in the military. RESULTS: After about 10 weeks in mental health clinics, severity scores for PTSD, sleep, depression, resilience, and disability all improved significantly. Of 681 patients tracked, 38% had clinically significant reductions on the PTSD Checklist (PCL) (i.e., "treatment response"), 28% no longer met criteria for PTSD on the PCL, and 23% did both (i.e., "clinical treatment success"). For the ultimate end point of "military treatment success," defined as meeting criteria for both clinical treatment success and reporting that their work-related disability was mild or better, 12.8% of patients succeeded. Depression scores were the most powerful predictor of treatment failure. CONCLUSIONS: Recovery from PTSD is possible during military service, but it is less likely in individuals with certain negative prognostic factors, most notably severe depression.

Reducing Stress and Burnout in Military Healthcare Professionals Through Mind-Body Medicine: A Pilot Program.

INTRODUCTION: A 6-week mindfulness training course, the Mind-Body Medicine (MBM) pilot program for staff, was implemented at a large military treatment facility to examine the preliminary efficacy of the program in reducing stress and burnout in military healthcare professionals. MATERIALS AND METHODS: A retrospective analysis was conducted of data collected from a single-arm prospective MBM pilot program. The program was designed to help staff members increase their awareness of burnout and its consequences and to learn how to utilize mindfulness-based self-care practices as a means for reducing stress and preventing burnout at work. Participants attended a 2-hour MBM group each week for a total duration of 6 weeks. Assessments of stress, resilience, anxiety, somatic symptoms, functional impairment, sleep quality, quality of life, and burnout were administered at baseline (T1), upon completion of the 6-week program (T2), and at least 3 months after program completion (T3). Multilevel modeling was used as the primary statistical model to assess changes in outcomes. Fifty-nine staff members completed assessments at T1, 31 (52.5%) at T2, and 17 (28.8%) at T3. RESULTS: Participants showed improvements on scores of perceived stress, resilience, anxiety, somatic symptoms, quality of life, and burnout variables from T1 to T2 and from T1 to T3 (P < .05). Additionally, they reported improvements in their knowledge, understanding, and utilization of MBM concepts and practices from T1 to T2 and from T1 to T3 (P < .05). CONCLUSIONS: Results from this pilot suggest that the MBM program has the potential to reduce occupational stress and burnout and improve well-being in military healthcare professionals.

ORION: A novel solution for tracking service members exposed to trauma and providing targeted outreach.

In response to the USS Fitzgerald (FTZ) and USS John S. McCain (JSM) collisions in 2017, Navy Medicine developed the Organizational Incident Operational Nexus (ORION) to track Service members and conduct targeted outreach (Caring Contacts) to those at elevated risk for psychological injury after unit-level, non-combat trauma exposure. A 1-year pilot was conducted to test the feasibility of implementing ORION. During the pilot, crews from the FTZ and JSM received Caring Contacts twice, once in winter/spring of 2018 and once in the summer/fall of 2018. Caring Contacts included reaching out to Service members over email, checking in with Service members over the phone, and connecting them to mental health resources, if desired. Sixty-two percent of the crews of the FTZ and JSM completed Caring Contacts. The Caring Contacts were well received and one in five Service members requested assistance connecting to mental healthcare through ORION. Additionally, all paygrades from enlisted to officers and 66% of Service members who separated from Service requested assistance connecting to mental healthcare through ORION. Findings from the Caring Contacts also demonstrated that 50% of the crews needed mental health support after the collision, with 30% of Sailors reporting accessing care since the collision and an additional 20% requesting care during the Caring Contacts. Overall, results suggest Service members greatly benefited from ORION's proactive approach to confidential outreach. Navy Medicine is now working toward implementing ORION throughout the enterprise and collecting more data to refine the program. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

A mind-body program for pain and stress management in active duty service members and veterans.

The Mind-Body Medicine (MBM) program at the Naval Medical Center San Diego, created in collaboration with the Benson-Henry Institute for Mind Body Medicine and the Home Base Program at Massachusetts General Hospital, is a 7-week program designed to facilitate stress management habits into patient treatment plans. The aim of this study is to test the feasibility and acceptability of a mind-body program for service members and veterans. Participants (N = 239) were primarily active duty service members of the U.S. Navy and Marine Corps reporting significant perceived stress (Stress Resiliency (SR) group; n = 124), or meeting criteria for chronic pain (Pain Management (PM) group; n = 115). Participants completed measures at preprogram and post-program assessing for perceived stress, pain, functional impairment, quality of life, and psychological and somatic symptoms. Changes in self-reported psychological symptoms and knowledge and practice of mind-body principles were examined. Participants across groups had significant improvement in most outcomes (perceived stress, response to stressful experience, functional impairment, sleep disturbance, depression, PTSD, and anxiety symptoms; and each quality of life domain aside from social relationships), with p values < .0017 (Bonferroni corrected level of significance). The SR group demonstrated significant improvements in primary outcomes of perceived stress and response to stressful experience, and the PM group demonstrated significant improvement in pain severity, but not perceived stress. Significant change was observed in knowledge and practice of mind-body medicine principles, and high satisfaction was reported. Results suggest that a mind-body program may improve physical and psychological functioning for service members, including those facing significant perceived stress and chronic pain.

Sexual Assault and Disabling PTSD in Active Duty Service Women.

INTRODUCTION: Sexual assault in the military is a major concern and may result in significant health problems, such as post-traumatic stress disorder (PTSD). Those developing disabling PTSD symptoms may require a disability evaluation. We examined disability evaluation trends for service women with PTSD to better understand characteristics associated with inability to continue Active Duty service. METHODS: This is a retrospective review of disability reports and electronic medical records for 322 Active Duty women diagnosed with and treated for PTSD by psychiatrists and psychologists at a large military treatment facility between 2011 and 2014. Service women requiring medical disability evaluation for PTSD (n = 159) were included in the study as "IDES cases" (Integrated Disability Evaluation System - IDES). A similar number of women, randomly selected from those seeking care for PTSD but not requiring disability evaluation during the same period, were included in the "control" group (n = 163). Analyzes done to evaluate differences between groups (IDES cases vs. controls) included demographic and service-related characteristics, history of chronic pain, and PTSD index trauma types, such as pre-military trauma and military sexual trauma (MST). Logistic regression was performed to identify the factors associated with inclusion in IDES. RESULTS: MST was the most frequent PTSD index trauma in the IDES group (73.6% vs. 44.8% of control group) and the most significant factor associated with IDES inclusion (OR 2.6, p = 0.032). Those in the IDES group had significantly greater number of mental health visits for PTSD (IDES: m = 68.6 vs. controls: m = 29.6) and more frequent chronic pain history (IDES 40.9% vs. controls 19.6%) than those in the control group. Approximately 65% of women in both groups had a history of childhood abuse, but childhood abuse, as a PTSD index trauma, was negatively associated with IDES inclusion (OR 0.293, p = 0.006). CONCLUSIONS: Active Duty service women with PTSD and a MST index trauma are much more likely to require disability evaluation (IDES) than those with PTSD due to other trauma types. IDES evaluation for conditions such as PTSD may result in early termination of military service and is a potential downstream consequence of MST. Service women requiring greater numbers of mental health visits for PTSD treatment may benefit from a multidisciplinary approach to treating concurrent health conditions, such as chronic pain. Those providing care for service women should evaluate for MST, chronic pain and pre-military trauma, such as childhood abuse; and aggressively treat these conditions to prevent PTSD and disability.

The effectiveness of an attention bias modification program as an adjunctive treatment for Post-Traumatic Stress Disorder.

Attention bias modification (ABM) may be an effective treatment for anxiety disorders (Beard, Sawyer, & Hofmann, 2012). As individuals with PTSD possess an attentional bias towards threat-relevant information ABM may prove effective in reducing PTSD symptoms. We examined the efficacy of ABM as an adjunct treatment for PTSD in a real-world setting. We administered ABM in conjunction with prolonged exposure or cognitive-processing therapy and medication in a community inpatient treatment facility for military personnel diagnosed with PTSD. Participants were randomized to either ABM or an attention control condition (ACC). While all participants experienced reductions in PTSD symptoms, participants in the ABM group experienced significantly fewer PTSD and depressive symptoms at post-treatment when compared to the ACC group. Moreover, change in plasticity of attentional bias mediated this change in symptoms and initial attentional bias moderated the effects of the treatment. These results suggest that ABM may be an effective adjunct treatment for PTSD.

Mind body medicine in the care of a U.S. Marine with chronic pain: a case report.

Many service members suffer from chronic pain that can be difficult to adequately treat. Frustration has led to more openness among service members to complementary and alternative medicine modalities. This report follows JK, a Marine with chronic pain related to an injury while on combat deployment through participation in a 6-week self-care-based Mind Body Medicine program and for 7 months after completion of the program. JK developed and sustained a regular meditation practice throughout the follow-up period. JK showed a noticeable reduction in perceived disability and improvements in psychological health, sleep latency/duration and quality of life. This report supports further study into the efficacy and feasibility of self-care-based mind body medicine in the treatment of chronic pain in the military medical setting.

Risk of PTSD in service members who were fired upon by the enemy is higher in those who also returned fire.

An unusual characteristic of the recent wars in Iraq and Afghanistan is that, because of attacks by snipers and improvised explosive devices (IED), many U.S. service members may come under attack without having exchanged fire. It was hypothesized that this would be associated with greater severity of post-traumatic stress disorder (PTSD) symptoms. The severity of self-reported symptoms of PTSD and depression were examined among service members who reported being shot at or attacked by an IED, those who had these experiences but who also shot at the enemy, and those who reported neither experience. Results showed that those with neither exposure reported the lowest symptom severity, but, contrary to expectations, service members who had been attacked but not shot at the enemy had less severe symptoms than those who had exchanged fire. This may support findings from earlier generations of veterans that shooting at or killing the enemy may be a particularly traumatic experience.

Effect of virtual reality PTSD treatment on mood and neurocognitive outcomes.

Virtual reality (VR) is an emerging tool to help treat posttraumatic stress disorder (PTSD). Previously published studies have shown that VR graded exposure therapy (VR-GET) treatment can result in improvements in PTSD symptoms. Less is known about the impact on depression, general anxiety, and neuropsychological functioning in patients with PTSD. This study examined changes in self-reports of PTSD, depression, and anxiety before and after treatment, and also examined neuropsychological functioning as assessed by a computerized test of simple reaction time, procedural reaction time, and performance on the congruent, incongruent, emotional, and neutral (match the color of the "nonsense word") Stroop tests. Results showed that subjects treated with VR-GET showed significant reductions in PTSD and anxiety severity and significant improvements on the emotional Stroop test. Changes in depression and other measures of neuropsychological function were not significant. Change scores on the emotional Stroop test did not correlate with changes in self-report measures of PTSD. Overall, these findings support the use of VR-GET as a treatment for PTSD but indicate that benefits may be narrowly focused. Additional treatments may be needed after or alongside VR-GET for service members with neuropsychological impairments.

Apparent comorbidity of bipolar disorder in a population with combat-related post-traumatic stress disorder.

Combat is often associated with the diagnosis of post-traumatic stress disorder. Battle may also lead to other emotional extremes. Sometimes this is enough to meet criteria for a diagnosis of bipolar disorder (BPD), but it is open to debate if this is clinically appropriate. This study examined the rate of BPD, as assessed by structured interview, in combat veterans who clinicians believed met the criteria for post-traumatic stress disorder but not BPD. Structured interviews were conducted with 109 such participants. Close to 81% endorsed a history of a major depressive episode, 34.9% endorsed a history of manic episode, and 27.5% endorsed a history of a hypomanic episode. According to the interviews, 54.1% participants experienced BPD, including 34.9% who experienced BPD type I. Clinicians were aware of these results and observed the individuals for a prolonged period afterward, but the clinical diagnosis did not change to include BPD in any of these individuals. Future research is needed to establish reliable and valid methods to make a diagnosis of BPD in the presence of comorbid conditions and stressors and thus guide clinicians with better treatment options.
