Military personnel's stress reactivity during pre-deployment in a war zone.

Many studies have been conducted on the numerous negative post-deployment outcomes for military personnel. However, data on service members' pre-deployment stress reactivity are absent. This is a serious gap in existing research, as stress has an important regulatory role. This study aimed to determine possible manifestations of military personnel's stress reactivity during pre-deployment in a war zone in eastern Ukraine. The study involved 270 Ukrainian service members (all male, aged 18 to 58 years). Sample 1 (n = 108) were preparing to be deployed for the first time, sample 2 (n = 84) were preparing to be deployed and had previous experience of deployment, and sample 3 (n = 108) were not preparing to deploy and had no previous deployment experience. We used the Ukrainian adaptation of the Giessen Subjective Complaints List (GBB-24), the Symptom Checklist-90-Revised (SCL-90-R), the Short Screening Scale for DSM-IV posttraumatic stress disorder and the Combat Exposure Scale (CES). We found that indicators for physical complaints, psychological problems and psychopathological and posttraumatic symptoms among service members from samples 1 and 2 were significantly higher than those of sample 3 in 15 of 18 cases (p < 0.001-0.05). The indicators obtained for sample 2 were higher than those of sample 1 in six of nine cases (p < 0.001-0.05). Both our study hypotheses were confirmed. The present findings can be used to develop efficient psychological interventions for military personnel during pre-deployment in a war zone.

Combat experiences, pre-deployment training, and outcome of exposure therapy for post-traumatic stress disorder in Operation Enduring Freedom/Operation Iraqi Freedom veterans.

The association between exposure to multiple potentially traumatic events (PTEs) and subsequent increased risk of post-traumatic stress disorder (PTSD) is well established. However, less is known about the relation between exposure to numerous PTEs, as is typical with military service, and treatment outcome. Furthermore, there has been little research examining military specific protective factors, such as pre-deployment preparedness, on PTSD treatment response. The current study investigated combat exposure and potential moderators of treatment outcome for exposure therapy in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans with PTSD. One hundred and eleven OEF/OIF veterans diagnosed with PTSD participated in 8 weeks of exposure therapy. Results indicated that increased combat exposure was associated with a reduced rate of change in PTSD symptoms but not depression symptoms. These findings were consistent across two measures of combat exposure. There was preliminary support for the moderating effect of pre-deployment preparedness on the association between combat exposure and treatment response. Together, these findings suggest that increased combat exposure is associated with poor treatment response in veterans with PTSD; however, this can be reduced by elevated pre-deployment preparedness.

A systematic review of psychological training or interventions given to UK military personnel prior to deployment.

INTRODUCTION: Predeployment stress management/mental health training is routinely delivered in an effort to mitigate potential adverse psychological effects. Little is known about the effectiveness of such interventions. METHODS: A systematic literature review explored research outcomes related to this subject, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines. An electronic database search using key terms identified studies published between January 2007 and March 2019. Comprehensive inclusion/exclusion criteria were applied and study quality was appraised by two reviewers using 12 criteria adapted from the Critical Appraisal Skills Programme (CASP) checklist. Papers were excluded if they were allocated CASP scores ≤10 out of 24. RESULTS: 2003 references were identified; 15 papers fulfilled inclusion criteria and quality threshold requirements. Included studies were randomised controlled trial design (n=8), quasi-experimental (n=5), case report (n=1) and cross-sectional (n=1). Duration of follow-up assessment varied from immediately postintervention to 24 months. The included studies were heterogeneous so clear recommendations relating to predeployment training for military personnel could not be made. Although somewhat disparate, predeployment interventions shared the aim of promoting prior to, during and after deployment health and well-being. Social benefits such as improved cohesion and improved stress management skills were identified in some studies, although substantial mental health and well-being benefits were not found. CONCLUSIONS: Evidence for the effectiveness of predeployment psychological interventions is scant. Every attempt should be made to use methods and measures to facilitate comparisons across studies, to attempt a longer follow-up timescale and to clarify key trainer characteristics.

Evaluation of neurosurgical training of French military surgeons prior to their deployment.

BACKGROUND: A specific training course was formalized in 2007 in order to facilitate the management of cranio-encephalic injuries by French military general surgeons during deployment, within the Advanced Course for Deployment Surgery (ACDS). The objective is to evaluate the neurosurgical pre-deployment training course attended by the military surgeons. METHODS: From June 2019 to September 2019, we conducted a cross-sectional survey in the form of a digital self-completed questionnaire, addressed to all graduated military surgeons working in the French Military Training Hospitals. The survey included: (1) a knowledge assessment; and (2) a self-assessment of the training course. The participating surgeons were classified into two groups according to their participation (group 1) or not (group 2) in the neurosurgical module. The main outcome was the score received on the knowledge assessment. RESULTS: Among the 145 military surgeons currently in service, 76 participated in our study (53%), of which 49 were classified in group 1 (64%) and 27 in group 2 (36%). Group 1 surgeons had a significantly higher score than Group 2 at the knowledge assessment (mean 21.0±7.1 vs. 17.8±6.0, P=0.041). The most successful questions were related to TBI diagnosis and surgical technique, while the least successful questions dealt with "beyond emergency care" and surgical indications. CONCLUSION: The French pre-deployment neurosurgical training course provides a strong neurosurgical background, sufficient to perform life-saving procedures in a modern conflict situation. However, neurosurgical specialized advice should be solicited whenever possible to assist the in-theatre surgeon in surgical decisions.

Using Simulation to Address a Training Gap in Battlefield Ocular Trauma: A Lateral Canthotomy and Cantholysis (LCC) Prototype Training System.

Over the past 15 years of conflict, eye injuries have ocurred at a steady rate of 5-10% of combat casualties, attributed to the enemy's use of improvised explosive devices. Many of these injuries result in a compartment syndrome of the orbit, easily decompressed through the use of a simple procedure called a Lateral Canthotomy and Cantholysis (LCC). Current training curricula at the U.S. Army Center for Pre-Hospital Medicine at Fort Sam Houston, Texas incorporates LCC training presented in lectures and taught using cadavers and goats (resources permitting), but lacks a LCC training device for the development of psychomotor skills. Requirements analysis, iterative design and development, and testing were performed for a simulation-based training system that may be used to practice the LCC procedure. Subject matter experts have conducted numerous reviews of the prototype system, where feedback is used to drive subsequent designs. Further work, including formal analysis of training effectiveness, will be performed to validate the training system. This will benefit will benefit military and civilian training programs by training psychomotor skills to enhance competency in the LCC procedure for preserving eyesight.

Pre-deployment dissociation and personality as risk factors for post-deployment post-traumatic stress disorder in Danish soldiers deployed to Afghanistan.

Objective: This study investigated whether pre-deployment dissociation was associated with previously identified post-traumatic stress disorder (PTSD) symptom trajectories from before to 2.5 years after military deployment. Furthermore, it examined whether the tendency to dissociate, pre-deployment personality factors, conceptualized by the Big Five model, and previous trauma represented independent risk factors for post-deployment PTSD symptoms. Method: This prospective study included the entire team of 743 soldiers from the Danish Contingent of the International Security Assistance Force 7 deployed to Afghanistan in 2009. Data consisted of self-report measures and were collected six times: before deployment; during deployment; and 1-3 weeks, 2 months, 7 months and 2.5 years after homecoming. Results: The findings indicate significant associations between pre-deployment dissociation and six PTSD trajectories (p < 0.001, η2 = 0.120). Based on mean differences in dissociation for the six trajectories, two main groups emerged: a group with high dissociation scores at pre-deployment, which had moderate PTSD symptom levels at pre-deployment and fluctuated over time; and a group with low dissociation scores at pre-deployment, which had low initial PTSD symptom levels and diverged over time. Our study also confirmed previous findings of a positive association between neuroticism and dissociation (r = 0.31, p < 0.001). This suggests that negative emotionality may be a vulnerability that enhances dissociative experiences, although a causal link cannot be concluded from the findings. Finally, pre-deployment dissociation, pre-deployment neuroticism and a history of traumatic events, as independent factors, were significant predictors of post-deployment PTSD (p < 0.001, R2 = 0.158). Conclusions: The study emphasizes the multiplicity of factors involved in the development of PTSD, and group differences in dissociative symptoms support the heterogeneity in PTSD. Further, this study points to specific aspects of personality that may be targeted in a clinical setting and in pre-deployment assessments in the military.

Objetivo: En este estudio investigamos si la disociación previa a un despliegue militar estaba asociada con trayectorias de síntomas de TEPT previamente identificadas desde antes hasta 2,5 años después del despliegue militar. Además, examinamos si la tendencia a disociarse, los factores de personalidad previos al despliegue, conceptualizados por el modelo Big Five y el trauma previo, representaban factores de riesgo independientes para los síntomas de TEPT posteriores al despliegue.Método: El estudio prospectivo actual incluyó a todo el equipo de 743 soldados del contingente danés de la Fuerza de Asistencia Internacional a la Seguridad Internacional 7 desplegados en Afganistán en 2009. Los datos consistieron en medidas de autoinforme, y se recogieron 6 veces: antes del despliegue, durante el despliegue. 1­3 semanas después del regreso al hogar, 2 meses después del regreso al hogar, 7 meses después del regreso al hogar y 2.5 años después del regreso al hogar.Resultados: Los hallazgos indican asociaciones significativas entre la disociación previa al despliegue y seis trayectorias de TEPT (p < 0.001, η2 = 0.120), y en base a diferencias medias en la disociación para las seis trayectorias surgieron dos grupos principales: Un grupo con puntuaciones de disociación altas previas al despliegue, que tenían niveles moderados de síntomas de TEPT antes del despliegue y fluctuaban con el tiempo. Un segundo grupo con puntuaciones de disociación bajas previas al despliegue, que tenían bajos niveles iniciales de síntomas de TEPT y divergían con el tiempo. Además, nuestro estudio confirmó los hallazgos previos sobre una asociación positiva entre el neuroticismo y la disociación (r = 0.31, p < 0.001). Esto podría sugerir que la emocionalidad negativa puede ser una vulnerabilidad que aumenta las experiencias disociativas, aunque no se puede concluir un vínculo causal a partir de los hallazgos. Finalmente, la disociación previa al despliegue, el neuroticismo previo al despliegue y una historia de eventos traumáticos, como factores independientes, fueron predictores significativos de TEPT posterior al despliegue (p < 0.001, R2 = 0.158).Conclusiones: El estudio enfatiza la multiplicidad de factores involucrados en el desarrollo del TEPT y las diferencias grupales en los síntomas disociativos apoyan la heterogeneidad en el TEPT. Además, este estudio apunta a aspectos específicos de la personalidad en los que se puede trabajarse en un entorno clínico, así como en las evaluaciones previas al despliegue en el ejército.

Educational software usability: Artifact or Design?

Online educational technologies and e-learning tools are providing new opportunities for students to learn worldwide, and they continue to play an important role in anatomical sciences education. Yet, as we shift to teaching online, particularly within the anatomical sciences, it has become apparent that e-learning tool success is based on more than just user satisfaction and preliminary learning outcomes-rather it is a multidimensional construct that should be addressed from an integrated perspective. The efficiency, effectiveness and satisfaction with which a user can navigate an e-learning tool is known as usability, and represents a construct which we propose can be used to quantitatively evaluate e-learning tool success. To assess the usability of an e-learning tool, usability testing should be employed during the design and development phases (i.e., prior to its release to users) as well as during its delivery (i.e., following its release to users). However, both the commercial educational software industry and individual academic developers in the anatomical sciences have overlooked the added value of additional usability testing. Reducing learner frustration and anxiety during e-learning tool use is essential in ensuring e-learning tool success, and will require a commitment on the part of the developers to engage in usability testing during all stages of an e-learning tool's life cycle.

The influence of pre-deployment cognitive ability on post-traumatic stress disorder symptoms and trajectories: The Danish USPER follow-up study of Afghanistan veterans.

OBJECTIVE: New trajectories of PTSD symptoms have recently been identified in war exposed army veterans. The aim of this army veterans study was to examine whether pre-deployment cognitive ability is associated with the risk of developing PTSD symptoms or non-resilient PTSD trajectories. METHOD: Follow up study in 428 Danish soldiers, deployed to Afghanistan in 2009, who were assessed at six occasions from pre-deployment to three years post-deployment. Pre-deployment vulnerabilities, deployment and homecoming stressors were measured. Pre-deployment cognitive test scores on Børge Priens Prøve (based on logical, verbal, numerical and spatial reasoning) were converted to a mean of 100 and with a standard deviation of 15. RESULTS: Higher pre-deployment cognitive ability scores were associated with lower risk of PTSD symptoms as assessed by the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) 2.5 years post-deployment (OR=0.97; 95% CI 0.95-1.00) after adjustment for educational length, baseline PCL-C score and perceived war-zone stress. Compared to a resilient trajectory, a non-resilient relieved-worsening trajectory (high baseline mental symptoms, being symptom free during deployment and a drastic increase in PTSD symptoms at the final assessments of PTSD symptoms) had significantly lower cognitive scores by a mean difference of 14.5 (95% CI 4.7-24.3). This trajectory (n=9) comprised 26.5% of soldiers with moderate-severe PTSD symptoms 2.5 years post-deployment. CONCLUSION: We confirmed an inverse association between pre-deployment cognitive ability and risk of PTSD symptoms, and observed significantly lower mean pre-deployment cognitive scores in one non-resilient PTSD trajectory. If replicated, this might inform relevant prevention efforts for soldiers at pre-deployment.

Availability and diversity of training programs for responders to international disasters and complex humanitarian emergencies.

INTRODUCTION: Volunteers and members of relief organizations increasingly seek formal training prior to international field deployment. This paper identifies training programs for personnel responding to international disasters and complex humanitarian emergencies, and provides concise information - if available- regarding the founding organization, year established, location, cost, duration of training, participants targeted, and the content of each program. METHODS: An environmental scan was conducted through a combination of a peer-reviewed literature search and an open Internet search for the training programs. Literature search engines included EMBASE, Cochrane, Scopus, PubMed, Web of Science databases using the search terms "international," "disaster," "complex humanitarian emergencies," "training," and "humanitarian response". Both searches were conducted between January 2, 2013 and September 12, 2013. RESULTS: 14 peer-reviewed articles mentioned or described eight training programs, while open Internet search revealed 13 additional programs. In total, twenty-one training programs were identified as currently available for responders to international disasters and CHE. Each of the programs identified has different goals and objectives, duration, expenses, targeted trainees and modules. Each of the programs identified has different goals and objectives, duration, expenses, targeted trainees and modules. Seven programs (33%) are free of charge and four programs (19%) focus on the mental aspects of disasters. The mean duration for each training program is 5 to 7 days. Fourteen of the trainings are conducted in multiple locations (66%), two in Cuba (9%) and two in Australia (9%). The cost-reported in US dollars- ranges from $100 to $2,400 with a mean cost of $480 and a median cost of $135. Most of the programs are open to the public, but some are only available by invitation only, such as the International Mobilization Preparation for Action (IMPACT) and the United Nations Humanitarian Civil-Military Coordination (UN-CMCoord) Field Course. CONCLUSIONS: A variety of training programs are available for responders to disasters and complex humanitarian emergencies. These programs vary in their objectives, audiences, modules, geographical locations, eligibility and financial cost. This paper presents an overview of available programs and serves as a resource for potential responders interested in capacity-building training prior to deployment.
