Virtual Reality Relaxation for Patients With a Psychiatric Disorder: Crossover Randomized Controlled Trial

Abstract

Background Virtual reality (VR) relaxation is a promising mental health intervention that may be an effective tool for stress reduction but has hardly been tested in clinical trials with psychiatric patients. We developed an easy-to-use VR self-management relaxation tool (VRelax) with immersive 360° nature videos and interactive animated elements. Objective To investigate the immediate effects of VR relaxation on negative and positive affective states and short-term effects on perceived stress and symptoms in patients with a psychiatric disorder, compared to standard relaxation exercises. Methods A randomized crossover trial was conducted in 50 patients receiving ambulatory treatment for anxiety, psychotic, depressive, or bipolar disorder. Participants were randomly assigned to start with VRelax or standard relaxation and used both interventions for 10 days at home. They completed 8 visual analog scales of momentary negative and positive affective states before and after each session. Global perceived stress and psychiatric symptoms were measured before and after both intervention periods. Treatment effects were analyzed with multilevel mixed model regression analyses and 2-way analysis of variance. Results Both VRelax and standard relaxation exercises led to a statistically significant immediate improvement of all negative and positive affective states. Compared to standard relaxation, VRelax resulted in a significantly greater reduction of total negative affective state (change 16.2% versus 21.2%; t1684=−2.02, 95% CI −18.70 to −0.28; P=.04). Specifically, VRelax had a stronger beneficial effect on momentary anxiety (t1684=−3.24, 95% CI −6.86 to −1.69), sadness (t1684=−2.32, 95% CI −6.51 to −0.55), and cheerfulness (t1684=2.35, 95% CI 0.51 to 5.75). There were no significant differences between short-term effects of the two treatments on global perceived stress and symptoms. Conclusions If the results of this trial are replicated and extended, VRelax may provide a much-needed, effective, easy-to-use self-management relaxation intervention to enhance psychiatric treatments.

Enhanced Mental Health with Virtual Reality Mental Hygiene by a Veteran Suffering from PTSD

“…Previously, VR has mainly been applied to patients with PTSD as an exposure to traumatic events, e.g., war [ 19 ]. In accordance with our results, a recent study of VR of nature videos improved feelings of anxiety and stress in patients with severe psychiatric disorders [ 20 ]. However, it cannot be ruled out that a large proportion of the intervention effect can be attributed to nonspecific factors and not to the specific method.…”

The growing field of digital psychiatry: current evidence and the future of apps, social media, chatbots, and virtual reality

“…Fewer studies have explored virtual reality treatments beyond exposure therapy, with the exception of skills training, which has also demonstrated positive results 99 . Pilot studies have also shown that virtual reality applications can guide people to learn therapeutic skills such as mindfulness 100‐102 , relaxation 103 and self‐compassion 104,105 . Using virtual reality as a vehicle to deliver experiences that help people develop skills to manage mental health difficulties may increase treatment engagement and efficacy.…”

Virtual Reality Relaxation for Reducing Perceived Stress of Intensive Care Nurses During the COVID-19 Pandemic

“…It is also possible that just “a pleasant getaway” from work produced the reduction in perceived stress. However, what argues against this is that in a previous study we found that VRelax when compared to standard relaxation exercises produces a greater improvement in terms of positive mood states, such as cheerfulness ( Veling et al, 2021 ). The additive effect of VR has been confirmed in a broad range of VR studies.…”

“…VR relaxation can support emotion-based coping, as well as meaning-focused coping strategies by leading to a positive affective state and immediate stress reduction ( Veling et al, 2021 ). VR relaxation is easy to use and has an advantage over regular relaxation exercises as it requires far less effort in terms of concentration and attention and leads to a larger increase in positive affect (e.g., happiness, etc.…”

“…VR relaxation is easy to use and has an advantage over regular relaxation exercises as it requires far less effort in terms of concentration and attention and leads to a larger increase in positive affect (e.g., happiness, etc. ; Veling et al, 2021 ). Our VR relaxation intervention (VRelax), consisting of calming natural environments, has shown to lead to immediate decrease in perceived stress and an improvement in overall positive affective states in people with psychiatric problems ( Veling et al, 2021 ).…”
