Immersive virtual reality as support for the mental health of elderly women: a randomized controlled trial

Several forms of virtual reality (VR) have shown promise in treating mental disorders. However, there is a lack of research investigating the use of multicomponent immersive VR. Therefore, this study aimed to evaluate the effectiveness of an immersive virtual reality (IVR) intervention that incorporated Japanese garden aesthetics, relaxation, and elements of Erickson’s psychotherapy in alleviating depression and anxiety symptoms among elderly women. Sixty women with depressive symptoms were randomly assigned to one of two treatment groups. Both groups received eight (twice a week for four weeks) low-intensity general fitness training sessions. The IVR group ( n = 30) received eight additional VR-based relaxation sessions, whereas the control group ( n = 30) received eight group relaxation. As outcome measures, the geriatric depression scale (GDS; primary) and Hospital Anxiety and Depression Scale (HADS; secondary) were administered before and after the interventions. The protocol was registered in the ClinicalTrials.gov PRS database (Registration number: NCT05285501). Patients receiving IVR therapy exhibited a greater significant reduction in the GDS (adjusted mean post-difference of 4.10; 95% CI = 2.27–5.93) and HADS (2.95; 95% CI = 0.98–4.92) scores than those receiving the control intervention. In conclusion, IVR with elements of psychotherapy, relaxation, and garden aesthetics may alleviate the severity of depression and anxiety symptoms in elderly women.
