Objective:

To synthesize the most common application areas and intervention characteristics in order to quantify and compare the effectiveness of VR for stress reduction across various settings and target groups, including specific demographics.

Key Findings:

• VR-based interventions have shown effectiveness in reducing perceived stress levels (PSLs) in the general population, with a noted percentage reduction in stress levels.
• The effectiveness of VR interventions may vary based on intervention design, VR content, technological features, and individual characteristics such as age and prior experiences.

Interpretation:

The study highlights the potential of VR as an accessible tool for stress reduction, emphasizing the need for tailored interventions to meet diverse individual requirements and improve overall mental health outcomes.

Limitations:

• Previous reviews have focused on specific target groups or interventions, leaving a gap in broader comparisons that could inform future research.
• The heterogeneity of stressors and individual characteristics may influence the effectiveness of VR interventions, suggesting a need for more nuanced analysis.

Conclusion:

Investigating predictors that enhance the stress-reducing effects of VR interventions is crucial for developing effective, individualized stress management tools, particularly in diverse populations.
