Feasibility of Group-Based Multiple Virtual Reality Sessions to Reduce Behavioral and Psychological Symptoms in Persons Living in Residential Aged Care

Objectives: To assess the feasibility of using group-based fully immersive virtual reality (VR) across multiple sessions to reduce behavioral and psychological symptoms (BPSs), including depression, anxiety, and agitated behaviors, in cognitively diverse aged care residents. Design: A 6-session feasibility trial was conducted within a residential aged care facility using convenience sampling to recruit N = 25 residents of varying cognitive capacity. Groups of 5 residents viewed 360-degree videos on a wireless head-mounted display to provide fully immersive VR experiences. Setting and participants: Half of the participants recruited from the 160-bed facility had a diagnosis of dementia (48%), whereas assessment with the Psychogeriatric Assessment Scale for cognitive impairment revealed that 64% experienced cognitive impairment (mild 20%, moderate 16%, and severe 28%). Additionally, 32% of participants had an existing anxiety or depression diagnosis. Measures: The Cornell Scale for Depression in Dementia, Generalized Anxiety Disorder 7-item, and Cohen Mansfield Agitation Inventory-Short were used to assess changes in persisting BPS pre- to postintervention period. The Person-Environment Apathy Rating apathy subscale, Observed Emotions Rating Scale, and a visual analog scale (Smileometer) were used to assess immediate mood responses from residents at every VR session. VR tolerability and resident feedback was also recorded. Results: Pleasure (z = -5.892, P < .001) and general alertness (z = -2.455, P = .014) of participants improved at VR sessions, whereas apathy diminished (z = -5.275, P < .001). Compared to baseline, postintervention depression was significantly lowered (z = -2.60, P = .009), whereas agitation increased (z = -2.98, P = .003). No significant changes in anxiety were observed. The quality of 360-degree videos and the device used did not induce any major VR-related negative side effects. Conclusions and implications: Overall group-based VR reduced depressive symptoms and apathy, and induced a positive emotional response in most residents, with few observed side effects. Results indicate feasibility of group-based VR technological innovation within RAC. (C) 2021 AMDA - The Society for Post-Acute and Long-Term Care Medicine.

Automated summary

Using fully immersive virtual reality (VR) in multiple sessions can reduce behavioral and psychological symptoms (BPS) in aged care residents, including depression, anxiety, and agitated behaviors, leading to reduced depressive symptoms and apathy, and inducing a positive emotional response.
