Using the natural environment to address the psychosocial impact of neurological disability: A systematic review

Nature-Based Design in Stroke Rehabilitation Environments: A Scoping Review

OBJECTIVE

To identify, examine, and map the characteristics of knowledge of nature-based design in stroke rehabilitation facilities, examine how research in this field has been conducted and identify gaps in knowledge.

BACKGROUND

Many stroke survivors have wide ranging impacts, resulting in long hospital stays to undertake rehabilitation. The physical environment can influence brain recovery; however, there is limited evidence to support the design of effective rehabilitation environments. Conversely, the health benefits available from connection with nature are well established. A nature-based design approach may have benefits and implications for the physical environment of inpatient stroke rehabilitation facilities; however, it is unclear what evidence exists in this field.

METHOD

This scoping review followed the JBI methodological guidance for the conduct of scoping reviews, with systematic searches of six databases.

RESULTS

Twenty-eight studies were included in the review. Aims and research methods varied widely. Investigations in 19 studies related to gardens and other designed outdoor nature-based environments. Other studies explored natural analogues, nature inside, inside/outside connections, and the natural environment. Findings from the studies were spread across the fields of design, use, exposure to, and engagement in nature-based environments.

CONCLUSION

The characteristics of knowledge underpinning nature-based design in stroke rehabilitation environments are highly diverse, and significant gaps exist in the evidence base. A framework developed during this review for mapping knowledge on the intentions and impacts for spaces and services in this field assisted to identify these gaps and may be applied to other areas of healthcare design research.

Enriched Environments in Stroke Units: Defining Characteristics and Limitations

BACKGROUND

Individuals with stroke rehabilitated in an enriched environment (EE) compared to a non-EE are more likely to participate in cognitive and social activities, promoting their rehabilitation and well-being. There is a need for a more comprehensive understanding of methods to implement EEs within complex health systems, particularly in stroke units.

OBJECTIVE

The aim of this systematic review was to compile the concept of an EE in stroke units.

METHODS

The literature was sourced from CINAHL, Embase, and Medline databases. A detailed screening and sifting process was used to identify relevant literature. Multiple reviewers independently appraised the identified literature using a Mixed-methods Appraisal Tool. After screening 336 studies, 11 were included.

RESULTS

This review reveals an EE is challenging to define and almost exclusively about activities based on access to individual and communal equipment. Generally, there are no common descriptions or conceptual agreements.

CONCLUSIONS

To the best of our knowledge, this is the first study to systematically review the concept of an EE in stroke units and shows that more studies on EEs are needed. The weak definitions and unclear theoretical backgrounds of an EE in the included studies could challenge operationalization. Future research should be based on more precise definitions of an EE and broader interventions that include changes to built and natural environments.

The impact of gardening on well-being, mental health, and quality of life: an umbrella review and meta-analysis

BACKGROUND

Gardening and horticultural therapy (HT) has been widely recognised as a multicomponent approach that has affected a broad range of health and well-being outcomes. The aim of this umbrella review and meta-analysis was to compare the findings of previous reviews on the impact of multiple gardening interventions and gardening attributes on different well-being constructs.

METHODS

Electronic databases including PubMed, Web of Science, Science Direct, the Cochrane Library, and Google Scholar were searched from inception to December 2022. Interventional and observational reviews were eligible for inclusion in this umbrella review. Outcome measures included mental well-being, health status and quality of life. The key exposure variables were gardening and horticultural therapy. Narrative synthesis was used to evaluate the overall impact of gardening and HT on study outcomes. For a subsample of studies with available quantitative data, a random effect meta-analysis was conducted.

RESULTS

This umbrella review included 40 studies (10 interventional studies, 2 observational studies, and 28 mixed interventional and observational studies). The reviewed studies reported an overall positive impact of gardening activities on several measures of mental well-being, quality of life, and health status. Meta-analysis showed a significant and positive effect of gardening and HT activities on well-being (effect size (ES) 0.55, 95% confidence interval (CI) 0.23, 0.87, p < 0.001).

CONCLUSIONS

Evidence from observational and interventional studies supports a positive role for gardening and HT activities on well-being and general health. Interventional studies with horticultural-based therapies were effective in improving well-being and quality of life both in the general population and vulnerable subgroups. The high degree of heterogeneity in the included studies cautions against any direct clinical implications of the study findings.

Green spaces and the impact on cognitive frailty: a scoping review

Some literature indicates that contact with green spaces can benefit health and wellbeing, but it is unclear whether this is protective of cognitive health in older people. Using Arskey and O'Malley's framework the aim was to investigate ageing, cognitive frailty and the effects of green access including any causality. The evidence was somewhat inconsistent but suggestive for a beneficial role of green space exposure on cognitive functions. Results suggested that globally, the poorer urban environments are high risk for older people's mental health and these places often lack parks and green spaces. There is evidence that the level of activity and social participation may be greater with access to green spaces and therefore reduces health risks. Green spaces seem to have a role in preventing cognitive frailty, especially for more vulnerable older populations living in poorer urban environments.

Psychosocial Aspects of Rehabilitation in Neurodegenerative Diseases and Fields of Approach

Psychosocial health is a concept included in definition of health by World Health Organization and corresponds to state of emotional and social well-being. In the context of neurological disorder, psychosocial health refers to social reintegration and psychological adjustment. Studies reporting that neurological diseases are associated with negative psychosocial health outcomes such as a decrease in the quality of life, a decrease in ability to establish and maintain social relationships, and an increase in high levels of depression, stress and anxiety have increased in recent years. Therefore, it is important to consider programs and interventions that can improve the psychosocial health of people with neurodegenerative diseases. Currently, it is not clear which psychosocial approaches can produce definitively positive results. The aim of this study is to examine how being an individual with Multiple Sclerosis and Parkinson's, which are the most common neurodegenerative diseases in the clinic, affects psychosocial health in the rehabilitation process and the existing evidence-based psychosocial approaches. For this purpose, a descriptive review was prepared by scanning English and Turkish articles with keywords on psychotherapeutic, psychosocial and mindfulness-based interventions and stress management, published in the determined databases in the last 10 years. Studies have shown that psychosocial approaches such as interventions for acquisition of social integration and adaptive coping strategies, cognitive and social behavioral therapy methods, concentration and movement-based mind-body exercises are effective in rehabilitation of neurodegenerative diseases. These approaches were reported to have benefits in reducing anxiety, depression and fatigue, improving sleep quality and quality of life, relationships, employment, level of participation, motivation and self-efficacy in exercise and physical activity, improving physical functions, facilitating difficult and personal experiences and adaptation to new life in rehabilitation processes and more evidence-based studies are needed.

What is the impact of nature on human health? A scoping review of the literature

Background

The burden of non-communicable diseases (including poor mental health) is increasing, and some practitioners are turning to nature to provide the solution. Nature-based interventions (NBIs) could offer cost-effective solutions by reconnecting individuals with nature, but the success of these interventions depends partially on the way in which people engage with blue and green spaces.

Methods

We conducted a scoping review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) and Cochrane guidelines to establish the evidence base for treating poor mental and physical health with NBIs. We searched five databases and the grey literature. Exposure was the active engagement with natural environments. The primary outcome was mental health and the secondary outcome was physical health defined using established metrics. All data were extracted to a charting table and reported as a narrative synthesis.

Results

952 studies were identified, of which 39 met the inclusion criteria. 92% demonstrated consistent improvements across any health outcome where individuals engaged with natural outdoor environments. Mental health outcomes improved across 98% of studies while physical and cognitive health outcomes showed improvement across 83% and 75% of studies respectively. Additionally, we identified 153 factors affecting engagement with nature, 78% of which facilitated engagement compared with 22% that reduced engagement. Aspects such as the sense of wilderness, accessibility, opportunities for physical activity and the absence of noise/ air pollution all increased engagement.

Conclusions

Further research (accompanied by a global improvement in study design) is needed to establish the magnitude and relative effect of nature-based interventions, and to quantify the compounding effect of factors that improve engagement with green and blue spaces. Nevertheless, this review has documented the increasing body of evidence in support of NBIs as effective tools to improve mental, physical, and cognitive health outcomes, and highlighted key factors that improve engagement with the natural world.

Psychological Well-Being and Nature Relatedness

The way people perceive contact with nature may impact their environmental attitudes and psychological well-being (WB). Nature relatedness (NR) refers to the affective, cognitive, and experiential aspects of individuals’ connection to nature. The aim of the presented research concentrates on the assessment of the relationship between well-being, self-control and connectedness with the natural environment. The data was collected via online questionnaire between March and April 2022. In the study, we combined descriptive statistics with analysis of variance. We also quantitatively assessed correlations between major components of NR scale and psychological WB across men’ and women’ inquires. The results showed that there is a statistically significant relationship between the general index of NR and overall psychological WB. Furthermore, correlation between specific aspects of NR and WB subscales were also observed. These interactions are considerable among both men and women. We have also identified a major correlation between NR and self-control, which indicates the link between the way a person approaches oneself and natural environment. Finally, the analysis provides evidence that women are on average more related to nature, although the men may benefit more from this kind of relationship. Further gender differences could be observed in terms of nature-relatedness perspective component, general self-control, score and overall NR score These relationships are highly vital among men while irrelevant among women.

Evaluating an Inpatient Created Art Installation on Perceptions of the Physical Environment, Health Status, and Rehabilitation Motivation

OBJECTIVES

A methodology to assess the impact of involving end users in therapeutic activities to address the hospital physical environment is provided. The impact of participating in a recreational art creation program with the aim of developing an art installation on the immediate feelings of participants and their perception of the physical rehabilitation environment (PPRE) and motivation to participate in rehabilitation (MPR) is investigated.

BACKGROUND

Rehabilitation unit design has largely excluded the perspectives of end users with disability. Including their aesthetic design contributions moves beyond contemporary approaches where their perspectives are considered.

METHODS

A two-period, mixed-methods pre-post intervention design involving within and between group comparisons is proposed. During Period 1, program participants and nonparticipants completed admission (T1) and discharge (T2) surveys including PPRE and MPR measures developed by the authors. Surveys pre and post each art session were completed. The art installation will be implemented within unit corridors. Period 2 participants will complete a T1 survey and their physical environment perceptions compared to Period 1 participants.

RESULTS

Participating in the recreational art program significantly improved immediate levels of calmness, happiness, pain, and physical health. There is a positive relationship between environment perception and rehabilitation motivation.

CONCLUSIONS

People with disability should be actively involved in healthcare environment design. Arts-based programs have relevance to people with neurological injury as it promotes essential sensory stimulation. The methodology and findings can encourage further work which involves end users in the design of healthcare environments and evaluates the impact of their involvement.

Effects of Indoor Plants on Human Functions: A Systematic Review with Meta-Analyses

The influences of indoor plants on people have been examined by only three systematic reviews and no meta-analyses. The objective of this study was therefore to investigate the effects of indoor plants on individuals’ physiological, cognitive, health-related, and behavioral functions by conducting a systematic review with meta-analyses to fill the research gap. The eligibility criteria of this study were (1) any type of participants, (2) any type of indoor plants, (3) comparators without any plants or with other elements, (4) any type of objective human function outcomes, (5) any type of study design, and (6) publications in either English or Chinese. Records were extracted from the Web of Science (1990–), Scopus (1970–), WANFANG DATA (1980–), and Taiwan Periodical Literature (1970–). Therefore, at least two databases were searched in English and in Chinese—two of the most common languages in the world. The last search date of all four databases was on 18 February 2021. We used a quality appraisal system to evaluate the included records. A total of 42 records was included for the systematic review, which concluded that indoor plants affect participants’ functions positively, particularly those of relaxed physiology and enhanced cognition. Separate meta-analyses were then conducted for the effects of the absence or presence of indoor plants on human functions. The meta-analyses comprised only 16 records. The evidence synthesis showed that indoor plants can significantly benefit participants’ diastolic blood pressure (−2.526, 95% CI −4.142, −0.909) and academic achievement (0.534, 95% CI 0.167, 0.901), whereas indoor plants also affected participants’ electroencephalography (EEG) α and β waves, attention, and response time, though not significantly. The major limitations of this study were that we did not include the grey literature and used only two or three records for the meta-analysis of each function. In brief, to achieve the healthy city for people’s health and effective functioning, not only are green spaces needed in cities, but also plants are needed in buildings.

Greener on the other side? an analysis of the association between residential greenspace and psychological well-being among people living with spinal cord injury in the United States

STUDY DESIGN

Secondary analysis of cross-sectional data from a multisite survey study.

OBJECTIVES

To describe associations between residential greenspace and psychological well-being among adults living with chronic spinal cord injury (SCI).

SETTING

Community.

METHODS

Participants were from the Spinal Cord Injury-Quality of Life (SCI-QOL) Calibration Study (N = 313). Geographic Information Systems (GIS) analysis was used to define five- and half-mile buffer areas around participants' residential addresses to represent community and neighborhood environments, respectively, and to create measures of natural and developed open greenspace. Associations of greenspace measures with two SCI-QOL psychological well-being domains (positive affect and depressive symptoms) were modeled using ordinary least squares (OLS) regression, adjusted for demographic, injury-related, and community socioeconomic characteristics.

RESULTS

People living in a community with a moderate amount of natural greenspace reported less positive affect and more depressive symptoms compared to people living in a community with low natural greenspace. At the neighborhood level, a moderate amount of developed open space was associated with less positive affect and more depressive symptoms than a low amount of developed open space.

CONCLUSIONS

Contrary to expectations, residential greenspace had a negative relationship with psychological well-being in this sample of adults with SCI. Understanding how and why natural spaces are associated with quality of life for people with mobility disabilities can influence public policy and urban planning designs to ensure that residential greenspaces are accessible and beneficial to all.

Greenspace and human health: An umbrella review

Multiple systematic reviews on greenspace and health outcomes exist, but the overall evidence base remains unclear. Therefore, we performed an umbrella review to collect and appraise all relevant systematic reviews of epidemiological studies on greenness exposure and health. We searched PubMed, Embase, and Web of Science from inception to June 28, 2021, and screened references of relevant articles. Systematic reviews with or without meta-analyses of epidemiological studies that examined the associations of greenness with any health outcome were included. Two independent investigators performed study selection and data extraction. We also evaluated the methodological quality of the included systematic reviews using the “Assessing the Methodological Quality of Systematic Reviews 2” checklist. A total of 40 systematic reviews and meta-analyses were included, of which most were cross-sectional studies conducted in high-income countries. Greenspace exposure was estimated with various objective and subjective parameters. Beneficial associations of greenspace with all-cause and stroke-specific mortality, CVD morbidity, cardiometabolic factors, mental health, low birth weight, physical activity, sleep quality, and urban crime were observed. No consistent associations between greenspace and other health outcomes (e.g., cancers) were observed. Most of the included systematic reviews and meta-analyses had one or more limitations in methodology. Our findings provide supportive evidence regarding the beneficial effects of greenspace exposure on some aspects of human health. However, the credibility of such evidence was compromised by methodological limitations. Better performed systematic reviews and meta-analyses as well as longitudinal designed primary studies are needed to validate this conclusion.

•

The evidence concerning greenspace and health outcomes remains unclear

•

We performed an umbrella review of 40 systematic reviews on greenspace and health

•

Greenspace exposure was estimated with various objective and subjective parameters

•

Greenspace was beneficially associated with several aspects of human health

Home Garden With Eco-Healing Functions Benefiting Mental Health and Biodiversity During and After the COVID-19 Pandemic: A Scoping Review

The COVID-19 pandemic has led to tremendous impacts on human lives and society, which are not only because of negative effects on people's mental health due to isolation policies and physical distance for mitigating the spread of SARS-CoV-2, but also because the incident post-acute sequelae of the coronavirus will cause mental disorders. A green environment is a health resource, which cannot only benefit human physical and mental health, but also increases biodiversity, contributes to flood mitigation, and cools urban areas. A home garden, as a kind of small green space, can provide ecosystem services with eco-healing functions in reducing mental stress during the isolation period of the COVID-19 pandemic through the garden itself and physical activities in it. Such an eco-healing approach within a mini-therapeutic landscape can also benefit biodiversity by enhancing plant diversity in residence and increasing biodiversity at a large scale. In this article, we propose a conceptual framework describing a home garden as "ecological medicine" with healing functions to improve mental health, as well as indirectly enhancing urban biodiversity. A home garden, as a mini-type of green landscape with biodiversity content, allows people to get close with nature so that it can promote comfortable and natural feelings during the pandemic. Furthermore, such an eco-healing home garden approach benefiting urban biodiversity can meet the challenges in maintaining environmental and mental health in post COVID-19 pandemic recovery, as well as preparing unknown next-surge risks with potential isolation regulations.

Effectiveness of Therapeutic Gardens for People with Dementia: A Systematic Review

This paper is a systematic review of quantitative studies conducted on the benefits of visiting gardens and gardening therapy for people with dementia (PWD) in an effort to assess the effectiveness of such treatments and obtain information on the most appropriate garden design for this population. This review followed the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) guidelines. Four databases were searched (PubMed, Web of Science, PsycINFO, Scopus), with no time limits. Out of a total of 480 articles considered, 16 studies were selected for review. In all but two of the studies examined, gardening therapy and the use of therapeutic gardens induced psychophysiological improvements in PWD. The areas showing the greatest effects were Engagement, Agitation, Depression/Mood, Stress, and Medication. It also emerged that interest in this sphere has been growing in the last decade, but there is still a shortage of empirical evidence of the beneficial effects of therapeutic gardens in relation to the type and severity of dementia, and of garden design guidelines. Despite the limited number of studies investigated, the review confirmed the benefits of gardening and therapeutic gardens in PWD. There is nonetheless a need to conduct more quantitative research to support currently-available evidence and generate more information, focusing on garden design criteria, in-garden activities, the type and severity of dementia examined, and effects on caregivers as well as on PWD.

Towards a standardized approach of assessing social context of persons receiving home care in Flanders, Belgium: the development and test of a social supplement to the interRAI instruments

BACKGROUND

Apart from a person's physical functioning, the early identification of social context indicators which affect patient outcomes - such as environmental and psychosocial issues - is key for high quality and comprehensive care at home. During a home care assessment, a person's biomedical and functional problems are typically considered. Harder to define concepts, such as psychosocial well-being or living arrangements, are not routinely documented, even though research shows they also affect functioning and health outcomes. The purpose of this study is to develop and test a concise, integrated assessment (BelRAI Social Supplement) that evaluates these social context indicators for persons receiving home care to complement existing interRAI- instruments.

METHODS

The development of the BelRAI Social Supplement is a multi-stage process, based upon the revised MRC-framework, involving both qualitative and quantitative research with stakeholders such as; clients, informal caregivers, care professionals and policy makers. The developmental process encompasses four stages: (I) item generation based on multiple methods and content validation by a panel of stakeholders (II) assessing feasibility and piloting methods, (III) early evaluation, and (IV) final evaluation. Stage II and III are covered in this paper.

RESULTS

During Stages I and II, a testable version of the BelRAI Social Supplement was developed in an iterative process. In Stage III, 100 care professionals assessed 743 individuals receiving home care in Flanders between December 2018 and December 2019. Using inter-item correlation matrixes, frequency distributions and regular feedback from the participants, the BelRAI Social Supplement was improved and prepared for Stage IV. The updated version of the instrument consists of four main sections: (1) environmental assessment; (2) civic engagement; (3) psychosocial well-being; and (4) informal care and support. In total, the BelRAI Social Supplement contains a maximum of 76 items.

CONCLUSIONS

The BelRAI Social Supplement was reviewed and shortened in close collaboration with care professionals and other experts in Flanders. This study resulted in an instrument that documents need-to-know social context determinants of home dwelling adults.

Who Moves After SCI? Individual, Health, and Neighborhood Predictors of Residential Mobility Among Participants in the National Spinal Cord Injury Model Systems Database

OBJECTIVE

To investigate residential mobility among community-living adults with spinal cord injury (SCI) and the individual, health, and neighborhood factors associated with the propensity to relocate.

DESIGN

Retrospective analysis of data from the National SCI Model Systems (SCIMS) Database collected between 2006 and 2018 and linked with the American Community Survey 5-year estimates.

SETTING

Community.

INTERVENTIONS

Not applicable.

PARTICIPANTS

People with traumatic SCI (N=4599) who participated in 2 waves of follow-up and had residential geographic identifiers at the census tract level.

MAIN OUTCOME MEASURES

Moving was a binary measure reflecting change in residential locations over a 5-year interval. Move distance distinguished nonmovers from local movers (different tracts within the same county) and long-distance movers (to different county or state). Move quality included 4 categories: stayed/low poverty tract, stayed/high poverty tract, moved/low poverty tract, and moved/high poverty tract.

RESULTS

One in 4 people moved within a 5-year interval (n=1175). Of the movers, 55% relocated to a different census tract within the same county and 45% relocated to a different county or state. Thirty-five percent of all movers relocated to a high poverty census tract. Racial and ethnic minorities, people from low-income households, and younger adults were more likely to move, move locally, and relocate to a high poverty neighborhood. High poverty and racial/ethnic segregation in the origin neighborhood predicted an increased risk for remaining in or moving to a high poverty neighborhood.

CONCLUSIONS

Although people with SCI relocated at a lower rate than has been reported in the general population, moving was a frequent occurrence postinjury. People from vulnerable groups were more likely to remain in or relocate to socioeconomically disadvantaged neighborhoods, thus increasing the risk for health disparities and poorer long-term outcomes among minorities and people from low-income households. These findings inform policy makers' considerations of housing, health care, and employment initiatives for individuals with SCI and other chronic disabilities.

Pressure injuries, obesity and mental health concerns on admission to rehabilitation are associated with increased orthopaedic rehabilitation length of stay

OBJECTIVE

To investigate the association between a set of comprehensive factors across international literature and rehabilitation length of stay.

METHOD

A chart audit of 197 Australian hospital rehabilitation unit orthopaedic inpatients (2016-2018) was conducted. Items significantly associated with length of stay throughout univariate regressions were entered into a subsequent hierarchical multiple regression analysis, where variables were regressed against length of stay in two steps. Items which were relevant prior to admission to the rehabilitation unit, or immediately upon admission, were regressed against length of stay during the first step, while variables which emerged during admission were entered during the second step.

RESULTS

Having pressure injuries during rehabilitation (p < .001), limited compliance in rehabilitation programs (p = .007), mental health concerns on admission to rehabilitation (p = .007), being obese (p < .001), and having significant pain impacting function (p = .03) were all independently significantly associated with an increased length of stay. Higher Functional Independence Measure motor (p < .001) subscale scores on admission to rehabilitation were associated with decreased length of stay. A hierarchical multiple regression analysis found that pressure injuries during rehabilitation (p = .002), being obese (p = .04), having mental health concerns on admission to rehabilitation (p = .03), and Functional Independence Measure subscale scores on admission (p = .04) were significantly associated with length of stay.

CONCLUSION

It is imperative that clinical programs and interventions promoting mental health outcomes, and addressing the distinct needs of obese inpatients, are delivered in the rehabilitation context.

Forest and Wellbeing: Bridging Medical and Forest Research for Effective Forest-Based Initiatives

Research Highlights: This review gives an overview of existing literature on the emerging topic of human wellbeing-forest contact nexus and provides a preliminary framework linking forests to wellbeing by highlighting key variables affecting this relationship. Background and Objectives: Existing literature reveals the psychological, physiological and social wellbeing benefits of contact with forest ecosystems; however, the role of forests in this relationship remains largely unexplored. The objectives of this review are twofold: (i) to provide an overview of the contributions of forest experiences to human wellbeing and the related interplay with forest ecosystems and (ii) to identify knowledge gaps to inform future research and systematize information available for forest managers and planners to support the development of effective forest-based initiatives. Materials and Methods: A scoping review was performed with a five-phase method integrating a systematic approach on Scopus, Web of Science and PubMed databases and snowball search. Studies were analyzed using a descriptive-analytical method. Results: Overall, 93 papers were included in the review. These are mainly from health-related sciences providing limited information for forest managers, planners and practitioners. Four main underlying variables of the forest-wellbeing relationship are identified: interaction, forest features, sensorial dimension of the forest and individual traits and reactions. Conclusions: Forest-based initiatives provide good opportunities for supporting public health and time spent in contact with forests seems to have a “health-bonus”. Whether and to what extent forest management can contribute to this is still poorly investigated. There is the need to better study causal relationships between specific forest features, type of interactions, frequency and “dose” of experiences, individual reactions and needs and wellbeing effects to maximize benefits from forest-based initiatives.

What Is the Impact of Engaging With Natural Environments Delivered Via Virtual Reality on the Psycho-emotional Health of People With Spinal Cord Injury Receiving Rehabilitation in Hospital? Findings From a Pilot Randomized Controlled Trial

OBJECTIVES

This study investigated (1) the effect of engaging with 20-minute simulated natural environments delivered via virtual reality (VR) on current mood state and (2) the effect of engaging with multiple VR sessions over a period of a week on the depressive symptoms of people with a spinal cord injury (SCI).

DESIGN

Randomized controlled trial design.

SETTING

Spinal Cord Injury Rehabilitation Unit in Australia.

PARTICIPANTS

Participants (N=24) were assigned to a group engaging in VR sessions during week 1 (group 1, n=10) or week 2 (group 2, n=14).

INTERVENTIONS

The intervention week involved participation in up to three 20-minute VR sessions over 3 consecutive days. The control condition involved regular rehabilitation practice over a week.

MAIN OUTCOME MEASURES

The Patient Health Questionnaire-8 (PHQ-8) was completed prior to the first week (T1), after the first week and prior to the second week (T2), and after the second week (T3). Current feeling states, including depressed/happy, anxious/relaxed, and not feeling good/feeling good, were rated immediately prior and after each VR session.

RESULTS

Levels of happiness, relaxation, and feeling good were significantly higher subsequent to engaging with each VR session. Between-group differences in PHQ-8 scores were significantly greater for participants who experienced the intervention during the first week compared to participants within the control group: intervention participants had significant improvements in psycho-emotional health. Within-group PHQ-8 scores were reduced for each group subsequent to experiencing the intervention; however, differences were not significant.

CONCLUSIONS

Engaging with simulated natural environments delivered via VR can favorably affect the psycho-emotional health of people with SCI receiving rehabilitation in hospital. Future research including larger samples and investigating the effect over a longer time period is required to confirm the findings presented.

School Green Space and Its Impact on Academic Performance: A Systematic Literature Review

Background: Scholars and policymakers have criticized public education in developed countries for perpetuating health and income disparities. Several studies have examined the ties between green space and academic performance, hypothesizing that green space can foster performance, and, over time, help reduce such disparities. Although numerous reviews have analyzed the link between nature and child health, none have focused on academic achievement. Methods: We identified 13 peer-reviewed articles that examined associations between academic outcomes, types of green spaces, and distances in which green spaces were measured around schools. Results: Of the 122 findings reported in the 13 articles, 64% were non-significant, 8% were significant and negative, and 28% were significant and positive. Positive findings were limited to greenness, tree cover, and green land cover at distances up to 2000 m around schools. End-of-semester grades and college preparatory exams showed greater shares of positive associations than math or reading test scores. Most findings regarding writing test scores were non-significant, and moderation effects of socioeconomic status, gender, and urbanization showed mixed results. Conclusions: The extant literature on green space and academic performance is small, shows mixed results, and mostly includes articles using observational, school-level research designs. Regardless, there is sufficient evidence to warrant further research on this topic, including effect moderation and mechanistic pathways.
