The purpose of the present study was to examine the clinical validation of a Virtual Reality Environment (VRE) designed to normalize eating patterns in Eating Disorders (ED). The efficacy of VR in eliciting emotions, sense of presence and reality of the VRE were explored in 22 ED patients and 37 healthy eating individuals. The VRE (non-immersive) consisted of a kitchen room where participants had to eat a virtual pizza. In order to assess the sense of presence and reality produced by the VRE, participants answered seven questions with a Likert scale (0-10) during the experience, and then filled out the Reality Judgment and Presence Questionnaire (RJPQ) and ITC-Sense of Presence Inventory (ITC-SOPI). The results showed that the VRE induced a sense of presence and was felt as real for both groups, without differences in the experience of "ease" with the VRE, sense of physical space, or the ecological validity assigned to the virtual kitchen and eating virtually. However, the ED patients reported paying more attention and experiencing greater emotional involvement and dysphoria after virtual eating. The results suggest that the VRE was clinically meaningful to the ED patients and might be a relevant therapy tool for normalizing their eating patterns.
本研究旨在检验虚拟现实环境(VRE)在饮食失调(ED)中矫正进食模式的临床验证。研究探索了 22 名 ED 患者和 37 名健康进食个体对 VR 诱发情绪、存在感和 VRE 真实性的效果。VRE(非沉浸式)由一个厨房房间组成,参与者需要在其中吃虚拟披萨。为了评估 VRE 产生的存在感和真实性,参与者在体验过程中用李克特量表(0-10)回答了七个问题,然后填写了现实判断和存在感问卷(RJPQ)和 ITC-存在感量表(ITC-SOPI)。结果表明,VRE 引起了存在感,两组都感觉很真实,对 VRE 的“易用性”、物理空间感或对虚拟厨房和虚拟进食的生态有效性的体验没有差异。然而,ED 患者报告在虚拟进食后更加关注、体验到更大的情绪投入和苦恼。结果表明,VRE 对 ED 患者具有临床意义,可能是一种矫正其进食模式的相关治疗工具。
