Homelessness among youth is devastating, with high rates of substance use disorders and mental health comorbidity. Mindfulness-based interventions that include meditation and mindfulness skills training reduce stress and symptoms of anxiety or depression. However, engaging high-risk youth in interventions is challenging. Virtual reality is a more flexible platform for delivering meditation and may be appealing to youth.
The study objectives were to evaluate the feasibility of delivering virtual reality meditation and of collecting outcome measures, including anxiety and physiologic stress.
A sample of 30 youth experiencing homelessness was enrolled in the study. Youth were randomized to receive 10 minutes of one of three interventions: (1) virtual reality meditation, (2) audio meditation (through a web-based platform), or (3) virtual reality imagery of historical pictures and text. Subjects who consented to the study attended two research visits. The first visit collected survey measures of demographics, mental health, and substance use, and oriented subjects to the intervention platforms. The second visit (1-3 days later) delivered the intervention and collected pre and post outcome measures of anxiety and physiologic stress (salivary cortisol). Changes in anxiety and cortisol at the second visit were compared across groups using a linear regression model in which the primary analysis compared virtual reality meditation to audio meditation and secondary analyses compared virtual reality meditation to virtual reality imagery.
Anxiety scores decreased in all groups, with a larger reduction among the virtual reality meditation group (difference=10.8) compared to the web-based meditation or virtual reality images groups (difference=5.8 and 5.0, respectively). After controlling for baseline values, there were no significant group differences in changes in anxiety scores or cortisol levels. In comparing virtual reality meditation and audio meditation, the effect size for anxiety was moderate (Cohen d=0.58) while the effect size for cortisol was small (Cohen d=0.08).
Preliminary results suggest that virtual reality meditation has a moderate benefit for anxiety but not physiologic stress. Future research is needed to confirm these results in a larger sample and to investigate whether the effects are sustained or increase with repeated use of virtual reality mediation. Virtual reality meditation appears feasible to deliver among homeless youth and merits further study.

青少年无家可归的状况极具破坏性,物质使用障碍和心理健康合并症的发生率很高。包括冥想和正念技能训练在内的基于正念的干预措施可减轻压力以及焦虑或抑郁症状。然而,让高危青少年参与干预具有挑战性。虚拟现实是一种更灵活的提供冥想的平台,可能对青少年有吸引力。
本研究的目的是评估提供虚拟现实冥想以及收集包括焦虑和生理压力在内的结果指标的可行性。
招募了30名无家可归的青少年作为研究样本。青少年被随机分配接受三种干预之一,时长为10分钟:(1)虚拟现实冥想,(2)音频冥想(通过网络平台),或(3)历史图片和文字的虚拟现实图像。同意参与研究的受试者参加了两次研究访视。第一次访视收集了人口统计学、心理健康和物质使用的调查指标,并让受试者熟悉干预平台。第二次访视(1 - 3天后)实施干预,并收集焦虑和生理压力(唾液皮质醇)的干预前后结果指标。使用线性回归模型比较各组在第二次访视时焦虑和皮质醇的变化,其中主要分析将虚拟现实冥想与音频冥想进行比较,次要分析将虚拟现实冥想与虚拟现实图像进行比较。
所有组的焦虑评分均下降,与基于网络的冥想组或虚拟现实图像组相比,虚拟现实冥想组的下降幅度更大(差异分别为10.8、5.8和5.0)。在控制基线值后,焦虑评分变化或皮质醇水平在各组之间无显著差异。在比较虚拟现实冥想和音频冥想时,焦虑的效应量为中等(科恩d = 0.58),而皮质醇的效应量较小(科恩d = 0.08)。
初步结果表明,虚拟现实冥想对焦虑有中等益处,但对生理压力无影响。需要进一步的研究在更大样本中证实这些结果,并调查这些效果是否会持续或随着虚拟现实冥想重复使用而增强。虚拟现实冥想在无家可归青少年中实施似乎可行,值得进一步研究。
