A machine of the same: Repetition in the foundational discourse of the Argentinean "being" (1976-1983).

Using the example of the military regime in Argentina (1976-1983) and relevant archival materials, this article demonstrates the prerequisite of exalted language in constructing an enemy and how a discursive 'machine of the same' was put into operation. The author argues that what made this operation unique is its structure of repetition that stimulated "the tendency to merge" what is "foreigner-to-the-ego", and the "enemy outside" into a single concept in the Argentinian national psyche.As a theoretical lens, the author examines the military regime's language through Freud's understanding of groups and civilization and Laplanche's proposition that cultural narratives in the form of mytho-symbolic explanations help us translate the sexual drive and offer a "solution" to the helplessness of the infant-adult.The author further claims that at other times a cultural narration functions as an anti-translation device when set against the emergence of a new net of significations. The nation's founding narrative of an Occidental-Spanish-Catholic "being" that first effaced its indigenous origins and then its Arabic and Jewish inheritance was brought back by the military regime as a mytho-symbolic narration that formed a shield against the repressed remnants of the enigmatic message pressing for a new translation.

Psychophysiological responses to a multimodal physiotherapy program in fighter pilots with flight-related neck pain: A pilot trial.

BACKGROUND: The physical and cognitive demands of combat flying may influence the development and persistence of flight-related neck pain (FRNP). The aim of this pilot study was to analyse the effect of a multimodal physiotherapy program which combined supervised exercise with laser-guided feedback and interferential current therapy on psychophysiological variables in fighter pilots with FRNP. METHODS: Thirty-one fighter pilots were randomly assigned to two groups (Intervention Group: n = 14; Control Group: n = 17). The intervention consisted of 8 treatment sessions (twice per week) delivered over 4 weeks. The following primary outcomes were assessed: perceived pain intensity (Numeric Pain Rating Scale-NPRS) and Heart Rate Variability (HRV; time-domain, frequency-domain and non-linear variables). A number of secondary outcomes were also assessed: myoelectric activity of the upper trapezius and sternocleidomastoid, pain catastrophizing (Pain Catastrophizing Scale-PCS) and kinesiophobia (TSK-11). RESULTS: Statistically significant differences (p≤0.05) within and between groups were observed for all outcomes except for frequency domain and non-linear HRV variables. A significant time*group effect (one-way ANOVA) in favour of the intervention group was found for all variables (p<0.001). Effect sizes were large (d≥0.6). CONCLUSIONS: The use of a multimodal physiotherapy program consisting of supervised exercise with laser-guided feedback and interferential current appears to show clinical benefit in fighter pilots with FRNP.

Internet-Guided Cognitive Behavioral Therapy for Insomnia Among Patients With Traumatic Brain Injury: A Randomized Clinical Trial.

Importance: Many military service members and veterans report insomnia after sustaining traumatic brain injury (TBI). Limitations of first-line treatment, cognitive-behavioral therapy for insomnia (CBT-I), include availability of qualified clinicians, low completion rates, and cost. Objective: To investigate the feasibility and efficacy of internet-guided CBT-I (eCBT-I) in military service members and veterans with insomnia and a history of TBI. Design, Setting, and Participants: This randomized clinical trial of fully remote internet-based interventions and evaluations was conducted from September 1, 2020, to June 30, 2021, with 3 months of follow-up. Participants included a volunteer sample of military service members and veterans aged 18 to 64 years with a history of mild TBI/concussion and at least moderately severe insomnia defined as an insomnia severity index (ISI) score of greater than 14 and Pittsburgh Sleep Quality Index of greater than 4. Self-reported race, ethnicity, and educational level were generally representative of the US military. Data were analyzed from October 21, 2021, to April 29, 2024. Intervention: Internet-based CBT-I delivered over 6 weekly lesson modules with assigned homework activities. Main Outcomes and Measures: The prespecified primary outcome measure was change in ISI score over time. Prespecified secondary outcome measures included self-reported measures of depression symptoms, posttraumatic stress disorder (PTSD) symptoms, sleep quality, migraine impact, and fatigue. Results: Of 204 people screened, 125 were randomized 3:1 to eCBT-I vs online sleep education, and 106 completed baseline evaluations (83 men [78.3%]; mean [SD] age, 42 [12] years). Of these, 22 participants (20.8%) were Hispanic or Latino and 78 (73.6%) were White. Fifty participants completed postintervention evaluations, and 41 completed the 3-month follow-up. Baseline mean (SD) ISI scores were 19.7 (4.0) in those randomized to eCBT-I and 18.9 (5.0) in those randomized to sleep education. After intervention, mean (SD) ISI scores were 13.7 (5.6) in those randomized to eCBT-I and 16.6 (5.7) in those randomized to sleep education. The difference in the extent of reduction in ISI scores between groups was 3.5 (95% CI,-6.5 to -0.4 [P = .03]; Cohen d, -0.32 [95% CI, -0.70 to -0.04]). In the eCBT-I group, the extent of insomnia improvement correlated with the extent of depressive symptom improvement (Spearman ρ = 0.68 [P < .001]), PTSD symptoms (ρ = 0.36 [P = .04]), sleep quality (ρ = 0.54 [P = .001]), and fatigue impact (ρ = -0.58 [P < .001]) but not migraine-related disability. Conclusions and Relevance: The findings of this randomized clinical trial suggest that fully remote eCBT-I was moderately feasible and effective for self-reported insomnia and depression symptoms in military service members and veterans with a history of TBI. There is great potential benefit for eCBT-I due to low availability and cost of qualified CBT-I clinicians, although optimization of completion rates remains a challenge. Future studies may use home-based objective sleep assessments and should increase study retention. Trial Registration: ClinicalTrials.gov Identifier: NCT04377009.

Development of Chronic Pain Conditions Among Women in the Military Health System.

Importance: The incidence of chronic pain has been increasing over the last decades and may be associated with the stress of deployment in active-duty servicewomen (ADSW) as well as women civilian dependents whose spouse or partner served on active duty. Objective: To assess incidence of chronic pain among active-duty servicewomen and women civilian dependents with service during 2006 to 2013 compared with incidence among like individuals at a time of reduced combat exposure and deployment intensity (2014-2020). Design, Setting, and Participants: This cohort study used claims data from the Military Health System data repository to identify ADSW and dependents who were diagnosed with chronic pain. The incidence of chronic pain among individuals associated with service during 2006 to 2013 was compared with 2014 to 2020 incidence. Data were analyzed from September 2023 to April 2024. Main Outcomes and Measures: The primary outcome was the diagnosis of chronic pain. Multivariable logistic regression analyses were used to adjust for confounding, and secondary analyses were performed to account for interactions between time period and proxies for socioeconomic status and combat exposure. Results: A total of 3 473 401 individuals (median [IQR] age, 29.0 [22.0-46.0] years) were included, with 644 478 ADSW (18.6%). Compared with ADSW in 2014 to 2020, ADSW in 2006 to 2013 had significantly increased odds of chronic pain (odds ratio [OR], 1.53; 95% CI, 1.48-1.58). The odds of chronic pain among dependents in 2006 to 2013 was also significantly higher compared with dependents from 2014 to 2020 (OR, 1.96; 95% CI, 1.93-1.99). The proxy for socioeconomic status was significantly associated with an increased odds of chronic pain (2006-2013 junior enlisted ADSWs: OR, 1.95; 95% CI, 1.83-2.09; 2006-2013 junior enlisted dependents: OR, 3.05; 95% CI, 2.87-3.25). Conclusions and Relevance: This cohort study found significant increases in the diagnosis of chronic pain among ADSW and civilian dependents affiliated with the military during a period of heightened deployment intensity (2006-2013). The effects of disparate support structures, coping strategies, stress regulation, and exposure to military sexual trauma may apply to both women veterans and civilian dependents.

Changes in emotion regulation difficulties and PTSD symptom severity in an intensive treatment program for PTSD.

BACKGROUND: Greater difficulties in emotion regulation (ER) and decreased use of adaptive ER strategies have been associated with higher levels of posttraumatic stress disorder (PTSD) symptoms. To date, limited research has explored whether ER improves with PTSD treatment or whether such improvements are linked with improvements in PTSD symptoms. METHODS: Veterans and service members with PTSD (N = 223) participated in a 2-week intensive treatment program (ITP) based in Cognitive Processing Therapy (CPT). ER was measured using the Difficulties in Emotion Regulation Short Form (DERS-SF) at baseline and on days 4 and 9 of treatment. PTSD symptoms were reported on the PTSD Symptom Checklist for DSM-5 (PCL-5) at baseline, on days 3, 5, 6, and 8 of treatment, and at post-treatment. RESULTS: DERS-SF scores decreased during treatment (Mchange = 5.12, d = 0.38). Baseline DERS-SF did not predict overall PCL-5 scores across timepoints (p = .377). However, scores on the DERS-SF over time were significantly associated with PCL-5 improvement over the course of treatment (p < .001, R2b = 0.07). Finally, improvements in all subscales of the DERS-SF across time except clarity were significantly associated with improvement in PCL-5 over time. LIMITATIONS: Additional treatment components in the ITP beyond CPT may have contributed to ER improvements. Conclusions are also limited by the use of self-report data. CONCLUSIONS: An intensive CPT-based treatment program for veterans and service members can lead to improved ER in two weeks. ER improvements are associated with PTSD symptom severity during the ITP.

Continuous Assessment of Active-Duty Army Special Operations and Reconnaissance Marines Using Digital Devices and Custom Software: The Digital Comprehensive Operator Readiness Assessment (DcORA) Study.

BACKGROUND: Continuous exposure to extreme and chronic stress from uncontrollable events has been linked to increased psychological and physiological reactivity. Prolonged, frequent deployments may test coping skills over time, ultimately rendering Servicemembers vulnerable to mental health problems and suicide. This study develops a methodology for accurately collecting holistic health measures from Servicemembers using digital tools, including custom-built phone software and body-worn sensors. METHODS: The secure research platform and mobile app continuously collect multiple health measures and, after data analysis, deliver continuously updated summary data back to the Servicemember. This system provides novel insights into the relationships between the measures while helping individuals track their progress toward self-established goals. Participants were given an iPhone (including the study app) and an Apple Watch. Participants tracked their data for more than 6 months and responded to baseline, daily, and weekly questions and assessments. Physiologic, psychologic, and cognitive assessment data across the Preservation of the Force and Family program (POTFF) domains were collected, displayed to the individual, and analyzed in aggregate. RESULTS: When coupled with custom-built software, this hardware can be elevated from a fitness tracker to a user-facing health monitoring, educational, and delivery system. CONCLUSION: This wearable system measured vital factors associated with the health and human performance of Servicemembers. In real-time, it engaged Servicemembers in health and human performance optimization practices to achieve a goal of prevention of physical or mental injury.

Recruit Profiles Across the U.S. Armed Forces: Implications for Increasing Gender Integration in Recruit Training.

INTRODUCTION: This article uses recent survey data from a study on gender integration at recruit training across the U.S. Armed Forces to examine service, gender, and training differences in recruit's gender attitudes, beliefs, and cohesion metrics. In addition to providing a descriptive understanding of our recruit sample, this article examines factors germane to gender integration at recruit training such as gender attitudes, sexist beliefs, and unit cohesion. MATERIALS AND METHODS: This article uses data from a survey of U.S. Marine Corps (USMC), U.S. Army, U.S. Air Force, U.S. Navy, and U.S. Coast Guard recruits as part of a USMC-commissioned study to develop alternate models and recommendations for increasing gender integration in USMC recruit training. At all sites but the USMC, recruits completed the survey 1 to 2 weeks before graduation. At the Marine Corps Recruit Depots, recruits participated in the survey at the beginning (week 2) and end (week 11) of their 13-week training cycle. A 19-question survey captured sociodemographic information, perspectives and experiences during recruit training, and gender attitudes and beliefs. Analyses were conducted on the sample with complete data on the measures reported, including those USMC recruits observed at both week 2 and week 11 (n = 629). Descriptive statistics (percentage) were calculated for all categorical outcome variables. Outcome variables (cohesion, gender, and sexism attitudes) were compared between groups using chi-squared tests or Fisher's exact tests, as appropriate. RESULTS: Recruits differed significantly across services in perceptions of unit cohesion on 3 of the 4 indicators: Platoon members are cooperative, know they can depend on each other, and really respect each other (P < .05). These differences appear to be driven by female recruit difference across service. They reported significant differences in gender role attitudes across the services, with USMC recruits being most likely to endorse traditional gender roles compared to other service recruits. Male USMC recruits were significantly more likely than their female peers to agree that men should achieve outside the home and women should take care of the home and family (21.3% versus 6.3%, P < .05). The only statistical differences in attitudes about equality of treatment and opportunity among recruits were between male and female USMC recruits. All items capturing sexist attitudes elicited statistically significant differences between male USMC recruits and male recruits in other services (P < .05). There were significant differences in all sexism measures between male and female USMC recruits (P < .05). There is a significant decline in some sexist attitudes between weeks 2 and 11 of training among male USMC recruits (P < .05). Nearly one-half to three-fourths of male USMC recruits hold sexist attitudes, even near the end of recruit training. CONCLUSIONS: The disparate gender and sexism attitudes of male USMC recruits compared with their peers in other services, and their fellow female USMC recruits suggest efforts to increase gender integration at entry-level training are needed, but also may be challenging since male USMC recruits report the highest levels of sexist attitudes among all recruits.

Recruit Perspectives on Gender Integration at Recruit Training: A Comparison by Service and Gender.

INTRODUCTION: Recruit training is the initial entry for enlisted personnel in the military. The Services execute gender-integrated recruit training differently. The U.S. Marine Corps (USMC) maintains same-gender platoons led by same-gender drill instructors in integrated companies; further integration occurs at select training events. The other Services train recruits in gender-integrated units with mixed-gender drill instructor teams. We examine recruits' experiences and perceptions of gender integration at recruit training, their desired level of integration, and preferences for increasing gender integration, comparing by Service and gender. MATERIALS AND METHODS: Recruit perspectives and experiences were captured in a 19-question survey (n = 632) and 90-min focus groups (n = 260) near graduation from recruit training. Data were collected from June to November 2021. Because of the Coronavirus disease (COVID-19) pandemic restrictions, the Navy and Air Force were not conducting gender-integrated recruit training during data collection. Outcome variables were compared cross-Service by gender and within Service by gender using chi-squared tests or Fisher's exact tests, as appropriate; focus group data were analyzed using initial and secondary coding schemes. Three USMC training models, varied by level of integration, were also analyzed (Male-Only, Series Track, and Integrated Company). RESULTS: Significant gender differences across and within Service emerged in recruits' experience being trained by an opposite-gender instructor. Male recruits had significant differences by Service (P < .001), and USMC female recruits reported being trained by male instructors more than their male peers by female instructors (Series Track P = .002; Integrated Company P < .001). In the focus groups, recruits described common differences with how men and women embodied being a drill instructor. Significant gender differences across (both male and female P < .001) and within Service were reported for closeness of training with opposite-gender peers (Air Force P = .028; U.S. Marine Corps (USMC) Integrated Company P = .010; Army P = .048), an expected finding given varied integration during data collection. Male and female recruits had significant differences by Service in their preference for integration at the lowest unit level (both male and female P < .001), with those who experienced integrated training showing higher levels of endorsement. In the focus groups, recruits articulated benefits and challenges of gender-integrated recruit training. Significant gender differences across Service emerged in preferences for more integration in specific training activities. Within Service, female USMC Integrated Company recruits wanted more integration in tactical/field, physical fitness, and classroom training than their male peers (P < .001 for all). In the focus groups, USMC recruits of both genders desired more integrated training events, particularly those involving combat and tactical skill development. CONCLUSIONS: This study provided an opportunity to examine recruit perspectives on gender-integrated training. Services valuing opposite-gender instructor exposure in recruit training must ensure that male recruits are being taught and led by female instructors given disproportionate demographics. Recruits who experienced integrated training were more supportive of integration, indicating that this experience may increase their support for gender-integrated training units and environments. Today's recruits understand that they are entering gender-integrated working environments, and our results indicate that they expect recruit training to mirror that reality.

The Role of Drill Instructors and Gender Integration at Recruit Training: Examining Intersections of Gender and Integration in the Recruit Training Environment.

INTRODUCTION: Drill instructors (DIs) are responsible for executing their Services' recruit training programs and for training recruits. DIs assume a variety of roles, including teaching and developing practical skills and knowledge, mentoring, modeling appropriate behavior and attitudes, motivating recruits for success during and after recruit training, applying and instilling discipline, and ensuring the safety and welfare of recruits. This article examines two major research questions at the intersection of gender, gender-integrated training, and the DI role: (1) What differences exist in how DIs experience their role by gender? and (2) how does gender-integrated recruit training affect DIs' approach to training? MATERIALS AND METHODS: This article draws from 87 semistructured interviews conducted with Service leaders, training cadre, and DIs in service of a broader Marine Corps interdisciplinary study on gender integration at recruit training. Interviews were conducted virtually and in-person with Marine Corps, Army, Navy, Air Force, and Coast Guard personnel from June to November 2021. Each interview was coded with initial and secondary codes developed through a flexible coding approach. Data were analyzed across and within relevant categories such as gender and Service to identify themes and patterns. RESULTS: Although the DI role was universally described as demanding and difficult, unique challenges for women consistently emerged from the data. The top reported challenges faced by female DIs were personnel shortages, work and family conflict, culture-driven sexism in the training environment from male peers and recruits, and pressure to excel above and beyond their male peers. In recruit training, DIs are responsible for executing gender-integrated practices. Service leaders, training cadre, and DIs described how gender integration practices affect their approach to the role and implementation of training, including addressing and dismantling sexism, shutting down recruit romantic relationships, training all recruits in an equal manner, knowing gender-specific grooming standards, increasing communication among DIs, and working with mixed-gender DI teams. CONCLUSIONS: Female DIs face additional challenges in and outside the role compared with their male peers, and some of these challenges are preventable. Staffing and personnel issues plague the female DI population and are a persistent and pervasive challenge to gender integration efforts. Women are a necessary and highly desirable population to fill the DI role, particularly as Services aim to expose recruits to leaders of both genders during their critical first training experience. DIs play an important role in ensuring the successful completion of recruit training, ultimately helping to build the future leaders of the military. The success of gender integration efforts depends on DIs' intentional approach to the process. Future research can build on this work by expanding the scope to other military training environments (beyond recruit training) and examining how DIs' own sociodemographic positions (e.g., gender, race, ethnicity, and sexual orientation) inform their perspective on and approach to equity in the training environment.

United States Marine Corps Recruit Training Demands Associated With Performance Outcomes.

INTRODUCTION: United States Marine Corps' (USMC) recruit training is a 13-week program designed to maximize physical and mental performance adaptations. The purpose of this study was to evaluate the training demands and characteristics that are associated with performance outcomes during USMC recruit training. MATERIALS AND METHODS: A total of 196 recruits (M = 97 and W = 99) were monitored and tested throughout training. Laboratory-based performance testing occurred at the start of weeks 2 and 11 and consisted of body mass assessments, countermovement vertical jump, and isometric mid-thigh pull. Military-specific performance testing occurred twice within the first 8 weeks of training and included the physical fitness test (PFT) and combat fitness test (CFT) implemented by the USMC. Resilience data were collected at week 2 using the Connor-Davidson Resilience Scale. Workload, sleep, and stress responses were monitored at weeks 2, 7, and 11. Recruits were provided with a wearable tracking device which utilized heart rate and accelerometry-based technology to determine energy expenditure (EE), distances (DIS), and sleep metrics. Data were averaged over a 3-day period. Salivary cortisol testing occurred at the start of each monitoring week. Change scores were calculated for performance tests, and body mass was calculated from data obtained at week 2 to week 11. Area under the curve was calculated for the workload, sleep metrics, and cortisol responses using the trapezoidal method. Pearson product-moment correlations (r) were used to assess the relationships between training demands and performance. An α level of 0.05 was used to establish significance. RESULTS: A moderate positive correlation was found between changes in body mass and peak power (P < .001; r = 0.43). Weak positive correlations were found between changes in body mass and peak force (P = .002; r = 0.28), as well as body mass and resilience (P = .03; r = 0.19). A moderate negative correlation was observed between changes in body mass and PFT (P < .001; r = -0.49). A weak negative correlation was found between changes in body mass and EE (P = .003; r = -0.24). A weak negative correlation was found between changes in peak power and EE (P = .001; r = -0.29). A weak positive correlation was found between changes in peak power and changes in CFT (P = .05; r = 0.19) A weak negative correlation was found between changes in sleep continuity and CFT (P = .02; r = -0.20). A weak negative correlation was found between cortisol and changes in PFT (P = .05; r = -0.20). A weak negative correlation was found between cortisol and both EE (P = .001; r = -0.27) and DIS (P = .045; r = -0.16). A weak negative correlation was found between EE and sleep continuity (P < .001; r = -0.34). Weak negative correlations were found between sleep duration and both DIS (P = .01; r = -0.18) and steps (P = .003; r = -0.21). CONCLUSIONS: Increases in body mass throughout training were positively associated with strength and power changes, but negatively related to PFT scores. Changes in peak power related to improvements in CFT scores; however, higher workloads (i.e., EE) were negatively associated with peak power. The identification of the USMC physical and physiological training demands that are associated with performance outcomes may be a valuable resource to guide conditioning efforts to boost military readiness.

The lived experience of military beneficiaries with amputations at the hip and pelvic level.

BACKGROUND: Hip- and pelvic-level amputations are devastating injuries that drastically alter patient function and quality of life. This study examined the experience of military beneficiaries with a hip- or pelvic-level amputation to better characterize their challenges and specific needs and to optimize treatment in the future. METHODS: We conducted a retrospective review of the Military Health System and identified 118 patients with a history of one or more amputation(s) at the hip or pelvic level between October 2001 and September 2017. Surviving participants (n = 97) were mailed a letter which explained the details of the study and requested participation in a telephonic interview. A total of six individuals (one female, five males) participated in structured interviews. RESULTS: The study group included four participants with hip disarticulations and two participants with hemipelvectomies (one internal, one external). All six participants reported significant challenges with activities related to prosthetic use, mobility, residual limb health, pain, gastrointestinal and genitourinary function, psychiatric health, and sexual function. CONCLUSIONS: These interviews highlight the unique needs of individuals with hip- and pelvic-level amputations and may improve access to higher echelons of care that would enhance the function and quality of life for these participants.

Applying the PTSD Checklist-Civilian and PTSD Checklist for DSM-5 crosswalk in a traumatic brain injury sample: A veterans affairs traumatic brain injury model systems study.

This study evaluates the use of the crosswalk between the PTSD Checklist-Civilian (PCL-C) and PTSD Checklist for DSM-5 (PCL-5) designed by Moshier et al. (2019) in a sample of service members and veterans (SM/V; N = 298) who had sustained a traumatic brain injury (TBI) and were receiving inpatient rehabilitation. The PCL-C and PCL-5 were completed at the same time. Predicted PCL-5 scores for the sample were obtained according to the crosswalk developed by Moshier et al. We used three measures of agreement: intraclass correlation coefficient (ICC), mean difference between predicted and observed scores, and Cohen's κ to determine the performance of the crosswalk in this sample. Subgroups relevant to those who have sustained a TBI, such as TBI severity, were also examined. There was strong agreement between the predicted and observed PCL-5 scores (ICC = .95). The overall mean difference between predicted and observed PCL-5 scores was 0.07 and not statistically significant (SD = 8.29, p = .89). Significant mean differences between predicted and observed PCL-5 scores calculated between subgroups were seen in Black participants (MD = -4.09, SD = 8.41, p = .01) and those in the Year 5 follow-up group (MD = 1.77, SD = 7.14, p = .03). Cohen's κ across subgroups had a mean of κ = 0.76 (.57-1.0), suggesting that there was moderate to almost perfect diagnostic agreement. Our results suggest the crosswalk created by Moshier et al. can be applied to SM/V who have suffered a TBI. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The UK VIRTUS helmet: User feedback from Operation TORAL in Afghanistan.

In 2015, the VIRTUS helmet was introduced to UK Armed Forces and will ultimately replace the Mark 7 combat helmet. The VIRTUS helmet has a reduced trimline compared to the Mark 7 helmet and can incorporate attachments such as a visor, mandible guard and nape protection. An anonymous questionnaire was provided to 200 UK Armed Forces personnel deployed to four locations on Operation TORAL in Afghanistan between September and October 2019. This is the first User feedback survey assessing the VIRTUS helmet in an operational environment. Users were measured to ascertain the fit of their helmet and asked to rate perceived helmet mass and comfort using a 5-point Likert scale. Users were also asked whether the VIRTUS helmet was better than previous helmets and about their use of the nape protection. The VIRTUS helmet was perceived to be an improvement over previously issued UK combat helmets in terms of both comfort and mass.

Neuropsychological Profiles of Deployment-Related Mild Traumatic Brain Injury: A LIMBIC-CENC Study.

BACKGROUND AND OBJECTIVES: Traumatic brain injury (TBI) is a concern for US service members and veterans (SMV), leading to heterogeneous psychological and cognitive outcomes. We sought to identify neuropsychological profiles of mild TBI (mTBI) and posttraumatic stress disorder (PTSD) among the largest SMV sample to date. METHODS: We analyzed cross-sectional baseline data from SMV with prior combat deployments enrolled in the ongoing Long-term Impact of Military-relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium prospective longitudinal study. Latent profile analysis identified symptom profiles using 35 indicators, including physical symptoms, depression, quality of life, sleep quality, postconcussive symptoms, and cognitive performance. It is important to note that the profiles were determined independently of mTBI and probable PTSD status. After profile identification, we examined associations between demographic variables, mTBI characteristics, and PTSD symptoms with symptom profile membership. RESULTS: The analytic sample included 1,659 SMV (mean age 41.1 ± 10.0 years; 87% male); among them 29% (n = 480) had a history of non-deployment-related mTBI only, 14% (n = 239) had deployment-related mTBI only, 36% (n = 602) had both non-deployment and deployment-related mTBI, and 30% (n = 497) met criteria for probable PTSD. A 6-profile model had the best fit, with separation on all indicators (p < 0.001). The model revealed distinct neuropsychological profiles, representing a combination of 3 self-reported functioning patterns: high (HS), moderate (MS), and low (LS), and 2 cognitive performance patterns: high (HC) and low (LC). The profiles were (1) HS/HC: n=301, 18.1%; (2) HS/LC: n=294, 17.7%; (3) MS/HC: n=359, 21.6%; (4) MS/LC: n=316, 19.0%; (5) LS/HC: n=228, 13.7%; and (6) LS/LC: n=161, 9.7%. SMV with deployment-related mTBI tended to be grouped into lower functioning profiles and were more likely to meet criteria for probable PTSD. Conversely, SMV with no mTBI exposure or non-deployment-related mTBI were clustered in higher functioning profiles and had a lower likelihood of meeting criteria for probable PTSD. DISCUSSION: Findings suggest varied symptom and functional profiles in SMV, influenced by injury context and probable PTSD comorbidity. Despite diagnostic challenges, comprehensive assessment of functioning and cognition can detect subtle differences related to mTBI and PTSD, revealing distinct neuropsychological profiles. Prioritizing early treatment based on these profiles may improve prognostication and support efficient recovery.

The role of unit cohesion and perceived resilience in substance use disorder.

Soldiers have high rates of substance use disorders (SUD), often in the aftermath of stressors experienced during military deployments. There are several factors that protect against SUD. For example, individual factors like perceived resilience and group factors such as unit cohesion may make someone less likely to abuse substances. However, there is little research on the differential influence of these resilience factors on SUD over and above deployment stressors. In this study, we examined the relative effects of perceived resilience, unit cohesion, and deployment stressors on SUD in a sample of 21,449 active duty and reserve soldiers from the U.S. Army (primarily White and male, mean age = 28.66, SD = 7.41) using structural equation modeling. We found that unit cohesion (ß = -.17) and perceived resilience (ß = -.16) had negative effects on SUD over and above deployment stressors. The study findings clarify research on resilience to SUD and have implications for addressing substance use in the military, specifically regarding the importance of building unit cohesion.

A reasoned action approach to meditation behavior among cadets at the United States Military Academy.

Military members face emotion-regulation challenges due to the high-pressure nature of the profession as evidenced by rates of mental health issues within military populations. Identifying behaviors that are efficient and effective at promoting emotion-regulation and helping military members adopt them is essential. Recently, meditation has been shown to reduce stress, enhance attention control and emotion regulation, along with reducing military-related Post Traumatic Stress Disorder symptoms. One way to promote this behavior in a military context is to enable future officers to adopt the behavior. We aimed to examine determinants of meditation intention and behavior among cadets at the United States Military Academy using the Reasoned Action Approach, a behavior framework used to explain and change behavior. By identifying these determinants, military practitioners can tailor meditation interventions to increase the likelihood that cadets will adopt the practice and eventually help soldiers under their command use meditation as well. We conducted a pilot study and a replication study that confirmed Reasoned Action Approach constructs were predictive of behavior and behavioral intention. Of significance was the perceived norm impact on meditation intention, specifically injunctive norms. Implications include the importance of authority figures within cadets' social context providing support for meditation's utility.

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.

Pain neuroscience education improves post-traumatic stress disorder, disability, and pain self-efficacy in veterans and service members with chronic low back pain: Preliminary results from a randomized controlled trial with 12-month follow-up.

Post-traumatic stress disorder (PTSD) and chronic low back pain (CLBP) are frequently co-morbid. Some research suggests that PTSD and CLBP may share common neurobiological mechanisms related to stress. Traditional biomedical education may be ineffective for PTSD and CLBP, especially when co-morbid. The purpose of this study is to determine if pain neuroscience education (PNE) is more effective than traditional education in reducing PTSD, disability, pain, and maladaptive beliefs in patients with CLBP. Participants with CLBP and possible PTSD/PTSD-symptoms were recruited for this study. Participants were randomly allocated to a PNE group or a traditional education group. The intervention included 30 minutes of education followed by a standardized exercise program once a week for 4-weeks with a 4 and 8-week follow-up and healthcare utilization assessed at 12-months. Forty-eight participants consented for this research study with 39 allocated to treatment (PNE n = 18, traditional n = 21). PNE participants were more likely to achieve a clinically meaningful reduction in PTSD symptoms and disability at short-term follow-up. At 12-months, the PNE group utilized healthcare with 76% lower costs. In participants with CLBP, PNE may reduce hypervigilance toward pain and improve PTSD symptoms. Participants who received PNE were more confident body-tissues were safe to exercise. These beliefs about pain could contribute to a decrease in perceived disability and healthcare consumption for CLBP.

Pre-existing parental stress and youth internalizing symptoms predict parent-reported COVID-related stress in military families.

Understanding the extent to which youth and families experienced COVID-related stress requires accounting for prior levels of stress and other associated factors. This is especially important for military families, which experience unique stressors and may be reluctant to seek outside help. In this prospective study, we examined the role of pre-pandemic family factors in predicting parent and youth stress during the COVID-19 pandemic. Participants were 234 families with at least one active-duty parent and a 3rd or 5th-grade child. Findings revealed that preexisting factors predicted youth and family COVID-related stress. Specifically, heightened pre-pandemic parental stress and youth internalizing symptoms were significant predictors of COVID-related stress. Implications for mental health professionals and other organizations supporting military parents and families during the COVID-19 pandemic as well as other times of upheaval are discussed.

Family Physician's Satisfaction Report: Military 2021 vs. Civilian 2020 and 2022.

INTRODUCTION: In the Medscape 2020 Compensation Report, family physicians ranked low for feeling fairly compensated, choosing their specialty again and choosing medicine again. However, the Medscape data may not represent military family physicians. METHODS: A large survey was emailed to 2,562 military family physicians via a military professional organization list-serve from February to April 2021. The inquiry included 6 statements pertaining to professional satisfaction. The main outcome measures were proportions of "agree" and "strongly agree." The proportions were compared to the Medscape Compensation Report 2020 and 2022. Statistical analysis was completed with a two-tailed Z-score for 2 populations. RESULTS: Sixty-one percent of military family physicians feel fairly compensated compared to 54% of civilian family physicians in 2020 and 55% in 2022 (P = .065, .119). Eighty-six percent of military family physicians would reselect medicine compared to 74% of civilian family physicians in 2020 and 73% in 2022 (P < .001 for both). Eighty percent of military family physicians would reselect their specialty again compared to 70% of civilians in 2020 and 68% in 2022 (P = .004, P = .001, respectively). CONCLUSIONS: Military family physicians were more likely to choose medicine generally and family medicine specifically again. Military family physicians and civilian family physicians do not statistically differ in feeling fairly compensated. A strong majority of military family physicians are satisfied with their military-sponsored medical education.
