Across three studies, we provide a proof-of-concept evaluation of an integrative psychotherapeutic application of virtual reality (VR) technology. Study 1 ( = 36) evaluated an unguided "safe-place" imagery task, where participants were instructed "to create a safe space… [such as] a scene, item, design, or any visual representation that makes you feel safe" using either the Google Tilt Brush application (VR condition), the standard Microsoft Paint application (2-D condition), or via eyes-closed mental imagery alone (IMG condition). Study 2 ( = 48) evaluated a narrative episodic recall task, where participants viewed their childhood and adult homes and places of schooling either using either the Google Earth VR application (VR condition) or the standard Google Earth application (2-D condition) or recalled these places with their eyes closed via mental imagery alone (IMG condition). Finally, Study 3 ( = 48) evaluated a guided wilderness imagery task, during which different scripts were narrated, specifically, a trail walk in autumn, a spring meadow, and a hillside walk in snowy winter, while either these same scenes were visually presented using the Nature Treks VR application (VR condition), the scenes were presented using the same software but shown on standard computer monitor (2-D condition), or participants' eyes were closed (IMG condition). Order of intervention format was randomized across participants. Across all three studies, quantitative survey ratings showed that the VR format of intervention delivery produced greater positive affect and satisfaction and perceived credibility ratings as an intervention for trauma- and stressor-related disorders and psychological well-being as rated by university students who varied in traumatic and stressful life event history and symptoms of posttraumatic stress disorder, whereas qualitative findings revealed additional themes of experiential response including increased experience of presence and vividness in the VR condition. Future research directions and clinical applications are discussed.
在三项研究中,我们对虚拟现实(VR)技术的综合心理治疗应用进行了概念验证评估。研究1(n = 36)评估了一项无指导的“安全空间”意象任务,参与者被指示“使用谷歌倾斜画笔应用程序(VR条件)、标准的微软画图应用程序(二维条件)或仅通过闭眼心理意象(IMG条件)来创建一个安全空间……[例如]一个场景、物品、设计或任何让你感到安全的视觉呈现”。研究2(n = 48)评估了一项叙事性情节回忆任务,参与者使用谷歌地球VR应用程序(VR条件)或标准的谷歌地球应用程序(二维条件)查看他们童年和成年后的家以及学校所在地,或者仅通过闭眼心理意象回忆这些地方(IMG条件)。最后,研究3(n = 48)评估了一项有指导的荒野意象任务,在此期间讲述了不同的脚本,具体来说,是秋天的小径漫步、春天的草地和雪天的山坡漫步,同时使用自然徒步VR应用程序以视觉方式呈现相同的场景(VR条件),使用相同软件但在标准电脑显示器上显示场景(二维条件),或者参与者闭眼(IMG条件)。干预形式的顺序在参与者中是随机的。在所有三项研究中,定量调查评分显示,对于有不同创伤和压力生活事件史以及创伤后应激障碍症状的大学生而言,作为创伤和应激源相关障碍及心理健康的一种干预措施,VR形式的干预交付产生了更大的积极影响、满意度和感知可信度评分,而定性研究结果揭示了体验反应的其他主题,包括在VR条件下存在感和生动感的增强。讨论了未来的研究方向和临床应用。
