Abstract

Background: The COVID-19 pandemic has resulted in increased psychological pressure on mental health since 2019. The resulting anxiety and stress have permeated every aspect of life during confinement.

Objective: To provide psychologists with an unbiased measure that can aid in the preliminary diagnosis of anxiety disorders and be used as an initial treatment in cognitive-behavioral therapy, this article introduces automated recognition of three levels of anxiety.

Methods: Anxiety was elicited by exposing participants to virtual environments inspired by social situations in reference to the Liebowitz social anxiety scale. Relevant parameters, such as heart rate variability and vasoconstriction were derived from the measurement of the blood volume pulse (BVP) signal.

Results: A long short-term memory architecture achieved an accuracy of approximately 98% on the training and test set.

Conclusion: The generated model allowed for careful study of the state of seven phobic participants during virtual reality exposure (VRE).

焦虑障碍的虚拟现实暴露辅助诊断系统:三级焦虑识别的长短期记忆架构。

背景:2019年以来，COVID-19大流行导致心理健康压力增加。由此产生的焦虑和压力已经渗透到坐月子生活的方方面面。目的:为了给心理学家提供一种公正的测量方法，可以帮助初步诊断焦虑症，并作为认知行为治疗的初始治疗，本文介绍了三个级别的焦虑的自动识别。方法:参照Liebowitz社交焦虑量表，将参与者暴露在由社交情境激发的虚拟环境中，从而引发焦虑。相关参数，如心率变异性和血管收缩是由测量血容量脉冲(BVP)信号得出的。结果:长短期记忆结构在训练集和测试集上的准确率约为98%。结论:生成的模型允许在虚拟现实暴露(VRE)期间仔细研究7名恐惧症参与者的状态。
