Virtual Reality-Based Psychotherapy in Social Anxiety Disorder: fMRI Study Using a Self-Referential Task

Area of Science:

• Neuroscience
• Psychiatry
• Psychology

Background:

• Virtual reality (VR) therapy shows efficacy comparable to cognitive behavioral therapy for social anxiety disorder (SAD).
• The impact of VR on pathological self-referential processing in SAD remains underexplored.

Purpose of the Study:

• To investigate changes in self-referential processing after VR treatment in individuals with SAD.
• To identify the neural mechanisms underlying these changes using functional magnetic resonance imaging (fMRI).

Main Methods:

• Participants with SAD and controls underwent clinical assessments and baseline fMRI scans.
• SAD participants received 6 sessions of VR-based exposure therapy.
• Post-treatment fMRI scans assessed self-referential word judgments (positive, negative, neutral).

Main Results:

• SAD participants showed altered neural responses in medial temporal and frontal cortexes during positive self-referential processing.
• Increased left insular and decreased right middle frontal gyrus activation occurred during negative self-referential processing.
• Post-VR therapy, reduced SAD symptoms correlated with increased activity in self-referential brain regions and decreased rumination.

Conclusions:

• fMRI findings suggest enhanced cognitive and physiological processing of self-referential information in individuals with SAD post-VR therapy.
• VR exposure therapy provides neural evidence for its effects on social anxiety and self-derogation.
