: A high number of patients who suffer the amputation of a lower limb will present psychological problems such as anxiety, depression, and post-traumatic stress disorder after surgery. This study embodies participants in a self-avatar with a right lower-limb amputation in a virtual reality environment. The aim was to determine if this experience increases anxiety levels compared to embodiment in a normal avatar. The study also examines whether body appreciation is related to anxiety levels. : Subjects completed the Body Appreciation Scale (BAS) questionnaire before being immersed in the virtual environment, the Visual Analogue Scale for Anxiety (VAS-A) after each condition, and the Embodiment Questionnaire at the end of the experiment. : Univariate analysis showed that participants reported significantly higher levels of anxiety when exposed to the virtual avatar with an amputation compared to the full virtual body avatar. These results indicate that lower levels of body appreciation were associated with higher levels of anxiety across conditions, suggesting that participants with lower body appreciation experienced greater psychological maladjustment (measured by anxiety) in response to the virtual scenarios. : The results suggest that the virtual avatar with a lower-limb amputation elicited significantly greater anxiety, and that body appreciation plays a key role in moderating this psychological response. Future research could focus on developing virtual exposure-based therapy for amputees using virtual reality to help reduce the anxiety experienced by patients during this process.
大量接受下肢截肢的患者术后会出现焦虑、抑郁和创伤后应激障碍等心理问题。本研究让虚拟现实环境中右下肢截肢的参与者拥有自我化身。目的是确定与拥有正常化身相比，这种体验是否会增加焦虑水平。该研究还考察身体欣赏与焦虑水平是否相关。：受试者在沉浸于虚拟环境之前完成身体欣赏量表（BAS）问卷，在每种情况后完成焦虑视觉模拟量表（VAS - A），并在实验结束时完成化身问卷。：单因素分析表明，与完整虚拟身体化身相比，参与者在接触截肢虚拟化身时报告的焦虑水平显著更高。这些结果表明，在各种情况下，较低的身体欣赏水平与较高的焦虑水平相关，这表明身体欣赏水平较低的参与者在面对虚拟场景时经历了更大的心理失调（以焦虑衡量）。：结果表明，下肢截肢的虚拟化身引发了显著更大的焦虑，并且身体欣赏在调节这种心理反应中起关键作用。未来的研究可以集中于为截肢者开发基于虚拟现实暴露的疗法，以帮助减轻患者在此过程中所经历的焦虑。
