A virtual reality intervention to improve formal caregivers' understanding of community-dwelling people with dementia: a pilot study.

BACKGROUND: The optimum approach to enhance the understanding toward dementia is to experience how patients feel as they experience the manifestations of the disease. The application of virtual reality (VR) and relevant innovative technologies for developing caregiver training programs allows caregivers to better understand dementia and empathize with patients. OBJECTIVES: To develop a VR-based experiential training course on individualized care for the behavioral and psychological symptoms of dementia (BPSD). METHODS: The participants were caregivers of patients with dementia. They assessed the usability of the VR product after the intervention and the VR experience as a preliminary measure of the effectiveness of the intervention using a usability scale and a self-reported appraisal scale, respectively. RESULTS AND CONCLUSION: Ten in-service and in-home caregivers completed the VR training course. The course yielded a usability score of 74.06 points, indicating excellent usability. The content validity index (CVI) of the self-reported VR experience appraisal scale ranged from 0.8-1, scale-level CVI was 0.81, and reliability (Cronbach's α) was 0.929. The mean score of the overall scale was 4.67 ± 0.33. These findings suggest that the VR-based experiential training course enabled the home caregivers to deepen their understanding of the BPSD shown by community-dwelling patients and, therefore, to provide better care services. The course developed in this study is the first VR course directed toward dementia care in Taiwan. Given its excellent usability, as well as the effectiveness of the VR experience appraisal scale for deepening the caregivers' skills in managing patients' BPSD symptoms, the course can be promoted and applied in caregiver training programs for dementia in the future.

Socially Assistive Robots for People Living with Dementia in Long-Term Facilities: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND AND OBJECTIVE: The purpose of our study was to explore the immediate and long-term effects of socially assistive robots (SARs) on neuropsychiatric symptoms (NPSs), behavioral and psychological symptoms of dementia (BPSD), positive emotional experiences, and social interaction in older people living with dementia. METHODS: We set keywords and used Boolean operators to search the CINAHL, Cochrane Library, EMBASE, IEEE Digital Library, MEDLINE, PsycINFO, PubMed, Web of Science, Scopus, and Chinese Electronic Periodical Service from inception to February 2022 for randomized controlled trials. The Cochrane Collaboration bias assessment tool was used to assess article quality, and RevMan 5.4.1 software was used to conduct the meta-analysis. RESULTS: A total of 14 studies were included in the meta-analysis. SARs can help people living with dementia reduce their NPS of depression and anxiety, provide happiness from positive emotional experiences, and improve their social interaction through conversation. However, there was no significant improvement in agitation behavior, overall BPSD, or quality of life in people living with dementia. In follow-up, it was found that the effect of SRT was limited. CONCLUSION: SARs can reduce depression and increase positive emotions in people living with dementia. They may also reduce the burden on healthcare workers during the COVID-19 pandemic.
