[Virtual reality therapy in anxiety disorders]

Area of Science:

• Psychiatry and Behavioral Sciences
• Human-Computer Interaction
• Clinical Psychology

Background:

• Traditional imaginal exposure therapy, a component of Cognitive Behavioral Therapy (CBT), faces limitations in patient applicability.
• Virtual reality (VR) has emerged as a potential alternative or supportive psychotherapeutic technique.
• Research has explored VR for anxiety disorders, specific phobias, eating disorders, drug dependence, pain management, and rehabilitation.

Purpose of the Study:

• To examine virtual reality exposure therapy (VRET) as an alternative treatment for mental disorders, particularly anxiety disorders.
• To assess the role of immersion and presence in VRET effectiveness.
• To explore VR's utility in managing conditions like post-traumatic stress disorder (PTSD).

Main Methods:

• Utilizing immersive technologies such as Head-Mounted Displays (HMDs) for individual use and Computer Automatic Virtual Environment (CAVE) for multi-user experiences.
• Leveraging VR's core characteristics: interaction, immersion, and presence.
• Controlling exposure intensity and adapting virtual environments to individual patient needs.

Main Results:

• High levels of immersion and presence in VR environments are associated with enhanced response to exposure therapy and sustained therapeutic gains.
• VRET effectively reduces patient avoidance of phobic stimuli by allowing repeated, supervised exposure.
• VR provides a controlled therapeutic setting, enabling therapists to manage exposure intensity and unexpected events.

Conclusions:

• Virtual reality exposure therapy presents significant advantages over traditional methods, especially for patients with avoidance behaviors or PTSD.
• Despite challenges like technology costs and potential side effects (nausea, dizziness), VR therapy offers a controlled, effective treatment modality.
• Therapist training in VR technology is crucial for optimizing its application and therapeutic outcomes.
