Summary

Objective Structured Clinical Examinations (OSCEs) are widely used in nursing education to assess clinical skills but are known to induce significant psychological and physiological stress due to performance anxiety, time pressure, and observation. Exam-related stress has been associated with changes in heart rate variability (HRV), particularly increased low-frequency/high-frequency (LF/HF) ratios, reflecting heightened sympathetic activity. Such stress may negatively affect cognitive performance, clinical competence, and professional readiness.

Nature-based virtual reality (VR) has emerged as a promising intervention for stress reduction by providing immersive, calming environments that promote relaxation and autonomic regulation. Previous studies suggest that short VR-based nature sessions can effectively reduce anxiety and may be more effective than two-dimensional (2D) nature videos, which represent a more accessible but less immersive alternative. However, evidence regarding the use of VR and 2D nature videos for managing stress during high-stakes clinical examinations such as OSCEs is limited.

This randomized controlled study aims to compare the effectiveness of nature-based VR and 2D nature videos in reducing OSCE-related stress among third-year nursing students using physiological (PPG-derived LF/HF ratio) and subjective (STAI and SUD) outcome measures.

Interventions

OTHER

Nature-Based Virtual Reality

Participants in the intervention group will receive a short nature-based virtual reality relaxation session prior to the OSCE examination. The VR content consists of calming natural environments with gentle visual transitions and ambient sounds designed to promote relaxation and reduce stress. The session is delivered using a head-mounted display and lasts approximately 5-10 minutes.

OTHER

2D Nature Video

Participants in the control group will watch a two-dimensional nature video prior to the OSCE examination. The video presents relaxing natural scenes accompanied by ambient sounds and is displayed on a standard screen for approximately 5-10 minutes as a non-immersive relaxation intervention.
