Introduction/Objective:
This study aimed to evaluate the impact of virtual reality-based cognitive behavioral group therapy (VR-CBGT) on reducing anxiety and depression in patients with Parkinson's disease.
Methods:
A randomized clinical trial with a pretest and posttest design was conducted involving 90 Parkinson's patients, from Roozbeh Hospital, Tehran in 2023. Participants were randomly assigned to an experimental group receiving 12 sessions of VR-CBGT over 3 months or a control group with no psychological intervention. Both groups completed the Beck Depression Inventory and Beck Anxiety Inventory before and after the intervention. Data were analyzed using multivariate analysis of covariance in SPSS-25.
Results:
The experimental group showed significant reductions in depression and anxiety compared to the control group. VR-CBGT explained 15% of the variance in depression (F = 6.148, P < 0.0005) and 31% in anxiety (F = 17.800, P < 0.0005).
Conclusion:
VR-CBGT effectively alleviates depression and anxiety in Parkinson's patients, offering a promising therapeutic approach. Integrating VR into CBT enhances engagement and real-life skill application, supporting its use as a complementary intervention.
