The incidence of posttraumatic stress disorder (PTSD) in returning OEF/OIF military personnel is creating a significant healthcare challenge. This has served to motivate research on how to better develop and disseminate evidence-based treatments for PTSD. One emerging form of treatment for combat-related PTSD that has shown promise involves the delivery of exposure therapy using immersive Virtual Reality (VR). Initial outcomes from open clinical trials have been positive and fully randomized controlled trials are currently in progress to further validate this approach. Based on our research group's initial positive outcomes using VR to emotionally engage and successfully treat persons undergoing exposure therapy for PTSD, we have begun development in a similar VR-based approach to deliver stress resilience training with military service members prior to their initial deployment. The Stress Resilience In Virtual Environments (STRIVE) project aims to create a set of combat simulations (derived from our existing Virtual Iraq/Afghanistan exposure therapy system) that are part of a multi-episode narrative experience. Users can be immersed within challenging combat contexts and interact with virtual characters within these episodes as part of an experiential learning approach for training a range of psychoeducational and cognitive-behavioral emotional coping strategies believed to enhance stress resilience. The STRIVE project aims to present this approach to service members prior to deployment as part of a program designed to better prepare military personnel for the types of emotional challenges that are inherent in the combat environment. During these virtual training experiences users are monitored physiologically as part of a larger investigation into the biomarkers of the stress response. One such construct, Allostatic Load, is being directly investigated via physiological and neuro-hormonal analysis from specimen collections taken immediately before and after engagement in the STRIVE virtual experience.
在从阿富汗和伊拉克战争归来的军事人员中,创伤后应激障碍(PTSD)的发病率给医疗保健带来了重大挑战。这促使人们开展研究,探索如何更好地开发和推广基于证据的PTSD治疗方法。一种新兴的与战斗相关的PTSD治疗方法显示出了前景,即使用沉浸式虚拟现实(VR)进行暴露疗法。开放临床试验的初步结果是积极的,目前正在进行完全随机对照试验,以进一步验证这种方法。基于我们研究小组使用VR让PTSD患者在暴露疗法中产生情感共鸣并成功治疗的初步积极成果,我们已开始开发一种类似的基于VR的方法,在军事人员首次部署前为他们提供压力恢复力训练。虚拟环境中的压力恢复力(STRIVE)项目旨在创建一组战斗模拟场景(源自我们现有的“虚拟伊拉克/阿富汗”暴露疗法系统),作为多集叙事体验的一部分。用户可以沉浸在具有挑战性的战斗情境中,并在这些情节中与虚拟角色互动,这是一种体验式学习方法的一部分,用于训练一系列心理教育和认知行为情感应对策略,这些策略被认为可以增强压力恢复力。STRIVE项目旨在在部署前将这种方法呈现给军事人员,作为一个项目的一部分,该项目旨在让军事人员更好地应对战斗环境中固有的各种情感挑战。在这些虚拟训练体验中,会对用户进行生理监测,这是对压力反应生物标志物进行更广泛调查的一部分。其中一个指标,即负荷应激,正在通过对参与STRIVE虚拟体验前后立即采集的样本进行生理和神经激素分析来直接研究。
