Using a Nature-based Virtual Reality Environment for Improving Mood States and Cognitive Engagement in Older Adults: A Mixed-method Feasibility Study

Carers and professionals' views on using virtual reality in dementia care: A qualitative study

BACKGROUND AND OBJECTIVES

Virtual reality (VR) interventions provide immersive, interactive computer-simulated virtual environments. There is interest in their use for people with dementia as they may provide stimulating experiences and improve dementia symptoms and quality of life. However, as more insight is needed about carers' and clinical professionals' perspectives to understand how VR may be implemented successfully, we elicited their views on the benefits of, and challenges to, using VR in dementia care.

METHODS

We conducted five qualitative focus groups involving 25 healthcare professionals and informal carers with experience of dementia care. Participants received a demonstration of a VR headset and content and were then questioned following a topic guide asking for views on benefits of, and challenges to, using VR for dementia care.

FINDINGS

The main findings addressed the benefits of, and concerns about, the impact and implications of VR on wellbeing, ethics, implementation, caregivers and services. Overall, participants had a positive attitude toward VR and made several suggestions for its future use to enable enjoyable and immersive experiences. Examples included suggestions to personalise VR content to accommodate heterogenous profiles and stages of dementia, co-developing protocols to address health risks and side effects and further investigating shared experiences of VR with caregivers.

CONCLUSION

Healthcare professionals and informal carers thought that VR had potential to enhance a holistic and personalised approach to dementia care. They suggested changes which could guide future implementation of VR interventions for dementia patients and their caregivers.

Naturalistic assessments across the lifespan: Systematic review of inhibition measures in ecological settings

Inhibitory control is essential for our everyday lives. Despite this, it is commonly assessed using non-naturalistic assessments. In this systematic review, we argue for the importance of taking an ecological approach to assess cognition. The aims are to present the state-of-knowledge in naturalistic assessments of inhibitory control, focusing on their methodological characteristics, including psychometric properties and user experience. PubMed, PsycINFO and Web of Science were searched until September 2024. Studies were included if they used at least one naturalistic method of assessing inhibition. The included studies (N=64) were grouped into three methodological categories: gamification, virtual reality, and brief, repeated assessments in participants' usual environment in the form of ecological momentary assessments. Sample sizes spanned three orders of magnitude (N=12-22,098). We report considerable heterogeneity in the types of tasks used, and the psychometric details reported. Nonetheless, naturalistic tasks were generally comparable with standardised equivalents, although some tasks assessed mixed-domain constructs. Tasks were feasible and acceptable for participants, with generally high completion rates and engagement. Recommendations for future research are discussed.

Exploring Subjective Mental Health Change in Older Adults after Experiencing an Immersive Virtual Reality (IVR) -Based Natural Environment

The study explored subjective mental health change in adults aged 60 to 100 by experiencing immersive virtual reality (IVR)-based on the natural environment. It investigated changes in thinking, behaviour, and emotions from a socioecological perspective. The study conducted quantitative surveys of 540 older adults via IVR who lived in 20 longevity villages in South Korea from Dec. 2022 to Nov. 2023. It also paralleled a qualitative study with 38 of the 540. Study results predicting subjective mental health changes after experiencing IVR in those over 70 showed the highest gladness and happiness. In over 70 compared with 60 to 69 ages, the study found that relieving stress and depression, gladness and happiness, and relaxing the mind have about two-fold subjective mental health changes after experiencing IVR. The study suggests that it can be utilized to promote subjective mental health through the experience of an IVR-based natural environment for older adults.

Virtual Reality Mental Health Interventions in Geriatric Care for Functional or Well-being Enhancement - A Scoping Review

PURPOSE

It has become common to use Virtual Reality (VR) for mental health interventions; however, its use in care of the elederly is limited, especially regarding mood and well-being. In this review, we summarize the results of current VR-based mental health interventions for this population.

METHODS

Peer-reviewed journal articles on immersive VR mental health intervention in seniors, published until 2022, were included.

RESULTS

There were 2697 results found in the database search, of which 40 articles met the inclusion criteria and were included in the final analysis. Most studies did not use an experimental design with randomized controlled trials and follow-up sessions. Function-oriented and entertainment-oriented intervention studies were categorized. VR-based geriatric mental interventions have grown rapidly since 2018, especially the number of interventions that promote wellbeing. The function-oriented interventions used active interactions with varied devices. Entertainment-oriented interaction was primarily passive, seldomly using hand controllers for moving activities. Generally, VR interventions improved the mental health of older adults.

CONCLUSION

Geriatric rehabilitation can benefit from this innovative technology to maintain cognitive functions and to improve the well-being of seniors. They have potential for use in aging care and in retirement homes. Future VR interventions may also involve promoting social interaction to combat loneliness among seniors.

How are nature-based interventions defined in mild cognitive impairment and dementia studies? A conceptual systematic review and novel taxonomy

OBJECTIVES

To systematically review research testing nature-based interventions for people living with mild cognitive impairment or dementia, and to report how authors have defined their interventions by presenting a taxonomy of the nature-based interventions.

METHODS

A conceptual systematic review of research published between 2008 and 2024 investigating nature-based interventions for people living with mild cognitive impairment or dementia was conducted. Three reviewers contributed independently. Exclusion criteria: not specifying if participants had mild cognitive impairment or dementia, only recruiting caregivers, no primary data, study protocols, abstracts, reviews, not peer-reviewed journal articles and any other grey literature. Intervention descriptions within the papers were thematically analysed.

RESULTS

Fifty-two articles reporting fifty-one studies were included. The most common interventions were nature virtual reality (VR technology) and gardening. From the definition data, we produced a taxonomy with overarching domains of: (a) Other terms used; (b) Characteristics; (c) Activities. Subdomains included: development or approach, modes of action, location, physical features, and activities. Some interventions could be grouped. Structure and standardisation of the interventions varied, with a lack of clear reporting.

CONCLUSION

This taxonomy provides conceptualisations of nature-based interventions that can be used by future researchers to guide the development, evaluation and reporting of robust interventions in this area.

Best practices for implementing a technology-based intervention protocol: Participant and researcher considerations

Technology-based interventions present a promising approach to support health and wellness for older adults with a range of cognitive abilities. Technology can enhance access to interventions and support scaling of programs to reach more people. However, the use of technology for intervention delivery requires particular attention to users' needs and preferences and ensuring the materials are adaptable and supportive of a diverse range of technology proficiency levels. We share best practices based on lessons learned from the deployment of a randomized controlled trial (RCT) wherein we delivered an 8-week social engagement intervention through a video technology platform called OneClick for older adults with varying cognitive abilities. We developed a set of best practices and guidelines informed by the lessons learned through this RCT implementation. Technology-based interventions require attention to the application (e.g., video calls), system requirements (e.g., system memory, broadband internet), training (e.g., adaptability based on user competency), and support (e.g., handouts, live contact). These best practices relate to user needs; training design; personnel responsibility; structuring delivery and content; and evaluating success. These research-based best practices can guide the design, development, and implementation of technology-based interventions to support older adults with varying cognitive abilities.

Comparing Conventional Physician-Led Education with VR Education for Pacemaker Implantation: A Randomized Study

INTRODUCTION

Education of patients prior to an invasive procedure is pivotal for good cooperation and knowledge retention. Virtual reality (VR) is a fast-developing technology that helps educate both medical professionals and patients.

OBJECTIVE

To prove non-inferiority of VR education compared to conventional education in patients prior to the implantation of a permanent pacemaker (PPM).

METHODS

150 participants scheduled for an elective implantation of a PPM were enrolled in this prospective study and randomized into two groups: the VR group (n = 75) watched a 360° video about the procedure using the VR headset Oculus Meta Quest 2, while the conventional group (n = 75) was educated by a physician. Both groups filled out a questionnaire to assess the quality of education pre- and in-hospital, their knowledge of the procedure, and their subjective satisfaction.

RESULTS

There was no significant difference in the quality of education. There was a non-significant trend towards higher educational scores in the VR group. The subgroup with worse scores was older than the groups with higher scores (82 vs. 76 years, p = 0.025). Anxiety was reduced in 92% of participants.

CONCLUSION

VR proved to be non-inferior to conventional education. It helped to reduce anxiety and showed no adverse effects.

Improving immersive experiences in virtual natural setting for public health and environmental design: A systematic review and meta-analysis of randomized controlled trials

In recent years, virtual reality (VR) technology has emerged as a powerful tool in the field of therapeutic landscapes. For hospitalized patients or individuals with limited mobility, VR provides highly personalized therapy by simulating authentic natural environments within a safe, convenient, and engaging setting. This study investigated the effectiveness of immersing patients in virtual natural environments for health recovery and compared the varying impacts of different types of landscapes on patients' recovery levels. The aim was to complement traditional medical approaches and enhance environmental design in the field of public health. Researchers systematically reviewed databases (January 2018 to August 2, 2023) to identify randomized controlled trials comparing the efficacy of virtual nature immersion with other treatments. The inclusion/exclusion criteria were established based on the population, intervention, comparison, outcomes, study design, and other aspects (expanded PICO) framework. The Cochrane tool was employed to assess the risk of bias. Meta-analysis was conducted by pooling the mean differences with a 95% confidence interval. Among 30 trials, a total of 2123 patients met the inclusion criteria, with 15 studies included in the meta-analysis. 30 trials met the criteria. Results show significant improvements in pain, anxiety, fear, and some physiological indicators with virtual nature-based treatments. On the other hand, natural scenes incorporating blue and green elements have been applied more extensively and have shown more significant effects. In comparison to conventional methods, this study strongly advocates that virtual reality environments are a crucial tool in bridging the gap between patients and nature, demonstrating their potential to reshape medical interventions and improve environmental design in the field of public health.

Impact of Virtual Reality-Based Group Activities on Activity Level and Well-Being Among Older Adults in Nursing Homes: Longitudinal Exploratory Study

BACKGROUND

In addition to illness, inactivity is a risk factor for high mortality in nursing homes. Using innovative technology, such as virtual reality (VR), for meaningful group activities could provide new opportunities for solving this problem. VR interventions have already been approved as a promising method for enhancing the health of older adults.

OBJECTIVE

In this study, we examined whether VR-based group activities can have a positive impact on activity level and group interaction among older adults living in nursing homes.

METHODS

We conducted a longitudinal study and provided VR interventions as a group activity once a week for 4 consecutive weeks in nursing homes. Participants were recruited based on the experience of the nursing staff members and the natural decisions of the older adults. Within a virtual cottage, designed according to the needs of the target group, older adults were able to perform daily tasks that they were no longer able to do in real life, such as gardening and making pizza. Overall, 2 psychologists measured the psychosocial capacities, activities of daily life, and well-being before and after the interventions using standardized instruments.

RESULTS

The results focus on a total of 84 older adults from 14 nursing homes who completed at least 3 VR interventions. The results indicate that several psychosocial capacities among the older adults improved, including adherence to regulations (P<.001; η²=0.122), flexibility (P<.001; η²=0.109), and group integration (P<.001; η²=0.141). Problems related to competence also showed a slight decrease (P=.04; η²=0.039). In addition, the VR intervention promoted their proactivity (P<.001; η²=0.104) and mobility (P=.04; η²=0.039). During the VR group intervention, older adults' well-being could be maintained at a high level. The results highlight the beneficial effects of VR intervention as a meaningful activity in nursing homes, showcasing the potential of VR applications in this setting.

CONCLUSIONS

This study provides a novel and naturalistic perspective, offering new insights into the use of VR in nursing homes. The VR intervention was well accepted and fulfilled the aim of enhancing capacity and well-being. It could be a meaningful group activity in nursing homes to improve social group interaction. To provide stronger evidence, randomized controlled trials are necessary.

Effectiveness of Virtual Reality-Based Well-Being Interventions for Stress Reduction in Young Adults: Systematic Review

BACKGROUND

Adolescents can be especially vulnerable to various stressors as they are still in their formative years and transitioning into adulthood. Hence, it is important for them to have effective stress management strategies.

OBJECTIVE

This systematic review investigates current well-being interventions that are aimed at reducing stress among young adults. In particular, interventions using the medium of virtual reality (VR) are explored.

METHODS

This mixed methods systematic review follows the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) guidelines, and papers were gathered from databases such as PsycINFO, PubMed, Science Direct, Web of Science, OpenGrey, and Edutopia. Predetermined criteria and specific keywords were used to search for the papers. Search results were screened and extracted with all article screening or extraction delegated among all authors. Any disagreements after reconciliation were settled by a third author. The quality and risk of bias of included studies were assessed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) Tool for Quantitative Studies. Studies were analyzed qualitatively.

RESULTS

In total, 20 studies were included, and qualitative analysis was performed to evaluate the effectiveness of VR-based interventions in 3 domains: nature, stress, and academics.

CONCLUSIONS

Studies using VR interventions, overall, promoted a reduction in stress and an increase in well-being. The findings suggest that VR may serve as an accessible and affordable medium of stress reduction for students and young adults. Larger sample sizes, and a greater number of included studies, may be required in future directions.

In sickness and in health-A scoping review on social virtual reality clinical applications

Objective

Evidence of virtual reality's (VR) efficacy in hospital settings coupled with the rise of inexpensive consumer devices have led to the development of social virtual reality (SVR) applications being incorporated in hospital settings. SVR provides opportunities for social interactions in virtual environments, allowing individuals to virtually socialize, regardless of geographic or mobility constraints. However, the full range of potential applications and the challenges of deploying SVR in hospital settings remain unexplored. We conducted a scoping review to characterize SVR applications studied in hospital settings to better understand SVR use for inpatient populations overall and in preparation for a National Institutes of Health (NIH)-funded project investigating SVR use with a specific clinical population.

Methods

In this scoping review, we searched MEDLINE, Embase, Scopus, APA PsycInfo, CINAHL, IEEE, and ACM Digital Library. After screening 2334 studies and reviewing 146 full texts, we identified 12 studies as eligible for analysis. Eleven of the 12 were published in the past 7 years, with none older than 12 years.

Results

As this is an emerging field, many publications were case or pilot studies, with small sample sizes ranging from 3 to 200 participants, and with mean participant ages that ranged from 9 to 75 years. Patient populations included those with stroke, cancer, COVID, as well as other health conditions.

Conclusion

Discussion of privacy and accessibility concerns was limited, as was the reported influence of SVR on measures associated with inpatient medical treatment (such as, adherence to clinical treatment while in the hospital while in a SVR intervention), which we highlight as critical issues for SVR's clinical use. We discuss our findings in the context of potential future directions for research in this area.

Customized virtual reality naturalistic scenarios promoting engagement and relaxation in patients with cognitive impairment: a proof-of-concept mixed-methods study

Being immersed in a natural context has a beneficial and pervasive impact on well-being. Virtual Reality (VR) is a technology that can help expose people to naturalistic scenarios virtually, overcoming obstacles that prevent them from visiting real natural environments. VR could also increase engagement and relaxation in older adults with and without cognitive impairment. The main aim of this study is to investigate the feasibility of a customized naturalistic VR scenario by assessing motion-sickness effects, engagement, pleasantness, and emotions felt. Twenty-three individuals with a diagnosis of cognitive impairment living in a long-term care home participated in our study. At the end of the entire VR experimental procedure with older adults, five health staff operators took part in a dedicated assessment phase focused on evaluating the VR procedure's usability from their individual perspectives. The tools administered were based on self-reported and observational tools used to obtain information from users and health care staff professionals. Feasibility and acceptance proved to be satisfactory, considering that the VR experience was well-tolerated and no adverse side effects were reported. One of the major advantages emerged was the opportunity to deploy customized environments that users are not able to experience in a real context.Trial Registration: National Institute of Health (NIH) U.S. National Library of Medicine, ClinicalTrials.gov NCT05863065 (17/05/2023).

Topical Cellular/Tissue and Molecular Aspects Regarding Nonpharmacological Interventions in Alzheimer's Disease-A Systematic Review

One of the most complex and challenging developments at the beginning of the third millennium is the alarming increase in demographic aging, mainly-but not exclusively-affecting developed countries. This reality results in one of the harsh medical, social, and economic consequences: the continuously increasing number of people with dementia, including Alzheimer's disease (AD), which accounts for up to 80% of all such types of pathology. Its large and progressive disabling potential, which eventually leads to death, therefore represents an important public health matter, especially because there is no known cure for this disease. Consequently, periodic reappraisals of different therapeutic possibilities are necessary. For this purpose, we conducted this systematic literature review investigating nonpharmacological interventions for AD, including their currently known cellular and molecular action bases. This endeavor was based on the PRISMA method, by which we selected 116 eligible articles published during the last year. Because of the unfortunate lack of effective treatments for AD, it is necessary to enhance efforts toward identifying and improving various therapeutic and rehabilitative approaches, as well as related prophylactic measures.

The effects of therapeutic virtual reality experience to promote mental well-being in older people living with physical disabilities in long-term care facilities

BACKGROUND

Mental well-being is poor in long-term care facilities (LTCF) residents. Physical disabilities, impaired social engagement, and environmental stress are also common in LTCF which exacerbate the decline of the mental well-being of older people living in LTCF. Protective elements, including nature-based, reminiscence, outdoor, and group activities, are known to be effective to promote the mental well-being of older people living in LTCF. However, limited by their physical disabilities and poor social support, older people living in LTCF are not likely to benefit from these effective measures. Virtual reality has been proven to be feasible to be environmentally unrestricted to providing LTCF residents with all protective elements promoting mental well-being. However, its effects on the mental well-being of LTCF residents living with physical disabilities are unclear.

METHODS

This study employs a single-blinded, two-parallel-group (intervention-to-control group ratio = 1:1), non-inferiority, randomized controlled trial. Eligible participants are aged 60 years or above, LTCF residents, and living with physical disabilities. The study will be conducted in LTCF. In the intervention group, participants will receive a 6-week VR experience program. In the control group, participants will receive the usual care provided by the LTCF. The primary outcome is mental well-being, as measured by World Health Organization Five Well-being Index at the time point of baseline (i.e., week 0) and after completion of the intervention (i.e., week 7). This study aims to recruit a total of 216 participants. Generalized estimating equations (GEE) will be used to examine the effects of the intervention.

TRIAL REGISTRATION

The trial has been registered at ClinicalTrials.gov (Identifier: NCT05818579 ), Registered on April 5, 2023. The latest version of the protocol was published online on 19 April 2023. All items come from the World Health Organization Trial Registration Data Set. This study has been approved by the Research Ethics Committee of Tung Wah College, Hong Kong (reference number: REC2023158). The findings will be disseminated in peer-reviewed journals, presented at international and local conferences with related themes, and shared in local media.

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.

Using Immersive Virtual Reality to Enhance Social Interaction Among Older Adults: A Cross-Site Investigation

Background and Objectives

Virtual reality (VR) applications are increasingly being targeted toward older adults as a means to maintain physical and cognitive skills and to connect with others, especially during the coronavirus disease 2019 era. Our knowledge about how older adults interact with VR is limited, however, since this is an emerging area and the related research literature is still rather slim. The current study focused specifically on older adults' reactions to a social-VR environment, examining participant's views about the possibility of meaningful interactions in this format, the impacts of social-VR immersion on mood and attitude, and features of the VR environment that affected these outcomes.

Research Design and Methods

The researchers designed a novel social-VR environment with features intended to prompt conversation and collaborative problem-solving among older adults. Participants were recruited from 3 diverse geographic locations (Tallahassee, FL; Ithaca, NY; and New York City, NY), and were randomly assigned to a partner from one of the other sites for social-VR interaction. The sample consisted of 36 individuals aged 60 and older.

Results

Reactions to the social VR were quite positive. Older adults reported high levels of engagement in the environment and perceived the social VR to be enjoyable and usable. Perceived spatial presence was found to be a central driver of positive outcomes. A majority of the participants indicated a willingness to reconnect with their VR partner in the future. The data also identified important areas for improvement that were of concern to older adults, such as the use of more realistic avatars, larger controllers more suited to aging hands, and more time for training/familiarization.

Discussion and Implications

Overall, these findings suggest that VR can be an effective format for social engagement among older adults.

Affective Out-World Experience via Virtual Reality for Older Adults Living with Mild Cognitive Impairments or Mild Dementia

Older adults with cognitive impairments may face barriers to accessing experiences beyond their physical premises. Previous research has suggested that missing out on emotional experiences may affect mental health and impact cognitive abilities. In recent years, there has been growing research interest in designing non-pharmacological interventions to improve the health-related quality of life of older adults. With virtual reality offering endless opportunities for health support, we must consider how virtual reality can be sensitively designed to provide comfortable, enriching out-world experiences to older adults to enhance their emotional regulation. Thirty older adults living with mild cognitive impairment or mild dementia participated in the study. Affect and emotional behavior were measured. The usability and the sense of presence were also assessed. Finally, we assessed the virtual reality experiences based on physiological responses and eye-tracking data. The results indicated that virtual reality can positively enhance the mental health of this population by eliciting a positive affective state and enhancing their emotional regulation. Overall, this paper raises awareness of the role of virtual reality in emotion elicitation, regulation, and expression and enhances our understanding of the use of virtual reality by older adults living with mild cognitive impairments or mild dementia.
