血压与基于声音的VR放松视频中自我报告压力之间的关系

虚拟现实（VR）放松环境日益被提议作为压力管理的便捷工具，然而在VR暴露期间，自我报告压力的生理相关性仍不清楚，尤其是血压（BP）。我们进行了一项受试者内研究（N=18），参与者通过HTC Vive Focus Vision头显观看放松的360度视频，这些视频被分为四种声音设计类别，如节奏性（RHYT）、非周期性（APRD）、连续性（CONT）和低环境（LOWE）声音。在每个类别后，使用Omron 3系列监测器记录收缩压（SYS）和舒张压（DIA），并通过固定间隔的0-100视觉模拟量表（VAS）收集自我报告压力。虽然总体血压在不同声音类别间无显著差异，但自我报告压力存在显著差异（Friedman卡方(4)=12.07，p=.017），其中节奏性声音引发的压力显著低于非周期性和连续性声音。关键的是，DIA（而非SYS）与跨条件下的自我报告压力显著相关（r=.31，p=.003）。这表明在短期VR暴露中，DIA可能比SYS更敏感地反映主观压力的生理指标。我们讨论了这些发现对设计和评估VR心理健康干预措施的启示，以及低成本生理传感与自我报告相结合的价值。

英文摘要

Virtual reality (VR) relaxation environments are increasingly proposed as accessible tools for stress management, yet the physiological correlates of self-reported stress during VR exposure remain unclear, particularly for blood pressure (BP). We conducted a within-subjects study (N = 18) in which participants viewed relaxing 360-degree videos, grouped into four sound-design categories, such as videos with rhythmic (RHYT), aperiodic (APRD), continuous (CONT), and low-ambient (LOWE) sound through an HTC Vive Focus Vision headset. Systolic (SYS) and diastolic (DIA) BP were recorded after each category using an Omron 3 Series monitor, and self-reported stress was collected via a 0-100 Visual Analogue Scale (VAS) with fixed intervals. While overall BP did not differ significantly across sound categories, self-reported stress did (Friedman chi-square(4) = 12.07, p = .017), with rhythmic sound eliciting significantly lower stress than aperiodic and continuous sound. Critically, DIA, but not SYS, correlated significantly with self-reported stress across conditions (r = .31, p = .003). This suggests that DIA may be a more sensitive physiological indicator of subjective stress than SYS in short VR exposures. We discuss implications for designing and evaluating VR mental health interventions and the value of low-cost physiological sensing alongside self-report.
