확장 현실 (XR) 시뮬레이션 전투 경험 후 불안 및 신체화 증상 변화 연구 = Changes in Anxiety and Somatization Symptoms following XR-based Simulated Combat Experience

다국어 초록 (Multilingual Abstract)

Despite the possibility that extended reality (XR)-based combat experience may affect psychological symptoms, little research has examined these relationships. Thus, the present study aimed to investigate whether anxiety symptoms (ANX) and somatization symptoms (SOM) change following XR combat experience, and to examine the effects of fatigue and cybersickness on these changes. Data were collected from 105 military personnel who participated in XR combat training in 2024. A paired-sample t-test showed that ANX levels did not significantly change, while SOM levels increased from before XR training (T1) to after XR training (T2). Fatigue and cybersickness were positively correlated with SOM at T2. However, only cybersickness had a distinct and strong effect on SOM at T2 in a multiple regression analysis. Additional repeated-measures ANOVAs were conducted using data from 30 participants who completed self-report surveys at three time points: T1 (pre-XR training), T2 (post-first XR training), and T3 (post-second XR training). ANX had no systematic changes over time, while SOM showed a quadratic change, increasing at T2 and then decreasing at T3. Based on these findings, the changes in SOM were interpreted in relation to the characteristics of XR training and associated physiological responses. The study concludes with a discussion of its limitations and implications for future research.
