Inclusion criteria
Participants:
This review will include studies focusing on adults aged 18 and over who are living with neurodegenerative conditions. Neurodegenerative conditions will encompass a range of disorders including, Huntington’s disease, Parkinson’s disease, Ataxia, Dystonia, Alzheimer’s disease, Multiple Sclerosis, and Motor neuron disease. Studies that focus on paediatric populations, or adults without diagnosed neurodegenerative conditions, will be excluded. Studies that include conditions beyond neurodegenerative diseases will still be considered for inclusion and, if possible, data will be disentangled.
Concept:
Concept of interest is the range of activities designed to support participation and social connectedness, aimed specifically at reducing loneliness and isolation. Activities may include, but are not limited to, physical activities, recreational programs, social gatherings, peer support groups, and the use of digital technologies as facilitators for such interactions. Although definitions of social participation may vary, the International Classification of Functioning, Disability and Health (ICF) (World Health Organisation 2001) defines social participation as 'involvement in a life situation' especially in relation to community, social and civic life. So, this definition will serve as an umbrella definition, underpinning our assessment of social participation in the included activities.
Context:
The context of this review encompasses community settings which may include, but are not limited to, local community centres, sports clubs, social clubs, residential care, and supported livig facilities. The review will consider studies from any geographic location and will be sensitive to cultural and sub-cultural factors that may influence the design, delivery, and outcomes of the activities. Studies that are based in acute hospital settings, inpatient rehabilitation, or other healthcare-specific environments will be excluded due to the focus of the scoping review being on community-based interventions and supports.
Types of Sources:
The scoping review will consider a range of study designs, including:
- Experimental and quasi-experimental study designs: randomised controlled trials, non-randomised controlled trials, before and after studies, and interrupted time-series studies
- Observational studies: prospective and retrospective cohort studies, case-control studies, and analytical cross-sectional studies
- Descriptive studies: case series, individual case reports, and descriptive cross-sectional studies.
- Qualitative studies: phenomenology, grounded theory, ethnography, qualitative description, action research, and feminist research.
- Systematic reviews will be screened, and any articles used in the review that meet the inclusion criteria and address the research questions, that have not already been identified in searches, will be included.
- Additionally, grey literature that provides relevant insights into the review concepts will also be included.
Studies that are purely theoretical without empirical data will be excluded due to the overarching aim of the review being to identify what is currently being used in real world settings. Moreover, articles that are not published in English will be excluded as the research team do not have the resources to translate the articles.
Methods
The proposed scoping review will be conducted in accordance with the JBI methodology for scoping reviews (Peters et al. 2020), the guidelines stipulated in the JBI Manual for Evidence Synthesis.
Search strategy
A two-step search strategy will be utilised, comprising of an initial search, and then a refined strategy, locating both published and unpublished work. Initial searches on MEDLINE and SCOPUS utilised the keywords "exercise," "social participation," "neurological conditions," "Parkinson’s," "
Huntington’s," "multiple sclerosis," "Alzheimer’s," "motor neuron disease," "community support," and "loneliness.". However, the search was very broad and pulled many irrelevant studies.
So, to further refine the strategy, truncations were added, such as, but not limited to, "Parkinson* disease", “Huntington* disease” and "motor neuron? Disease". The use of an asterisk is useful where a term may have different word endings, such as Huntington, Huntingtons and Huntington’s; the asterisk will search for all word endings. Moreover, extra terms such based on social participation and intervention types were incorporated based on recommendations from a subject librarian at the Cardiff University School of Healthcare Sciences. The final comprehensive search strategy, underpinned by the initial keywords and refined with additional index terms, truncations and synonyms, was collaboratively developed with the subject librarian to ensure robustness of the search strategy. This meticulous strategy was subsequently adapted to and will be applied across several databases, including SCOPUS, CINAHL (via EBSCO), PsycINFO (via OVID), and MEDLINE (via OVID), with the complete search strategy details for MEDLINE outlined in supplementary files, under 'Appendix I'.
The scoping review will selectively include studies published in the English language. This decision is grounded in practical considerations, primarily the constraints associated with the translation of non-English studies which may entail resource-intensive processes and potential for inaccuracies. Moreover, as qualitative studies will be included in this review, using translation software may result in miscommunications between the true essence of what was meant, and what the translation software produces. However, it is acknowledged that this language restriction may introduce a bias by omitting relevant studies published in other languages. The impact of this limitation on the review’s findings will be discussed in the final report. The temporal scope of the search has been established from the year 2008 onwards. This starting point is significant as it coincides with the ratification, and implementation, of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) (United Nations 2006). The convention represents a shift in the domain of disability rights, advocating a more inclusive society and development of effective policies for persons with disabilities, intrinsically linked to the grounding of this review’s topic. It is anticipated that scholarly research and interventions focused on enhancing participation and addressing isolation amongst individuals with neurodegenerative conditions would have increased following the implementation of this specific international human rights treaty in 2008, resulting from the UNCRPD. Thus, 2008 serves as a strategic marker to capture literature reflective of this enhanced global focus on accessibility, social inclusion, and the rights of persons with disabilities in health research and practice.
The databases to be searched include:
- MEDLINE (via OVID): For its extensive biomedical literature, including neurology and rehabilitation studies.
- CINAHL (via EBSCO): For nursing and allied health literature relevant to patient care and community support.
- PsycINFO (via OVID): For psychological aspects of disability, participation, and integration.
- SCOPUS: For a broad scope of scientific literature.
The search will include grey literature accessed via ProQuest Dissertations and Theses Global, to capture data not available in academic journals, focusing on conference proceedings, organisational reports, and government documents related to social participation and neurodegenerative conditions.
Study/Source of evidence selection
Following the search, all identified citations will be collated and uploaded into EndNote 20.6 (Clarivate Analytics, PA, USA) and duplicates removed by using the ‘Find Duplicates’ dialog function in EndNote. Following a pilot test, titles and abstracts will then be screened by two or more independent reviewers for assessment against the inclusion criteria for the review. Potentially relevant sources will be retrieved in full, and their citation details imported into a subgroup in EndNote 20.6 (Clarivate Analytics, PA, USA). The full text of selected citations will be assessed in detail against the inclusion criteria by the lead reviewer, with any queries settled amongst 2 or more independent reviewers. Reasons for exclusion of sources of evidence at full text that do not meet the inclusion criteria will be recorded and reported in the scoping review. Any disagreements that arise between the reviewers at each stage of the selection process will be resolved through discussion, or with an additional reviewer/s. The results of the search and the study inclusion process will be reported in full in the final scoping review and presented in a PRISMA flow diagram (Page et al. 2021).
Data extraction
Data will be extracted from papers included in the scoping review solely by the lead reviewer using a data extraction tool. The data extraction tool for this scoping review will be an adapted form based on the established Cochrane data extraction template. The Cochrane template, known for its rigorous approach to systematic reviews, has been modified to better fit the unique requirements of this study (Cochrane Effective Practice and Organisation of Care 2017) .The adapted template will include fields specific to our research questions such as mode of delivery, neurodegenerative condition researched, and activity details, whilst also keeping components of the original template such as, study design, and key findings. The Cochrane template's comprehensive nature allows for capturing nuanced data on study design, population demographics, intervention specifics, and outcomes, providing a structured approach to extract and analyse the relevant data systematically. The process will be piloted on a small subset of included studies to confirm the template’s efficacy in capturing all necessary information and will be revised accordingly. Any modifications made to the original Cochrane template will be documented to maintain transparency of the methodology. Moreover, any disagreements that arise between reviewers will be resolved through discussion, or with an additional reviewer/s. The final version of the adapted data extraction form is included in supplementary files under 'Appendix II'.
Data analysis and presentation
The analysis of the extracted data will be designed to align directly with the review's overarching objective: to map the evidence on social participation and support mechanisms for adults with neurodegenerative conditions. The presentation of the data will be carried out using both graphical/diagrammatic representations and tabular formats to facilitate clear, concise, and comprehensive communication of the findings. For graphical representation, we will employ charts and diagrams where appropriate; one way in which we aim to do this is via pie charts displaying the distribution of neurodegenerative conditions included in the final scoping review. Moreover, diagrammatic representations such as PRISMA flow diagrams (Page et al. 2021) will be used to illustrate the study selection process, while thematic maps will be used to depict the relationships and themes identified within the literature. Tables will be used to summarise the characteristics and findings of the included studies, allowing for quick reference and comparison. These tables will cover study details such as authors, year, study design, population, intervention types, outcomes, and key findings related to social connectedness and neurodegenerative conditions. A narrative summary will accompany the visual and tabular presentations of data, providing context and interpretation of the results. This narrative will explain how the findings relate to the review's objectives and questions, discussing the nuances and implications of the evidence, and identifying gaps in the current research landscape.
In preparation for the final review, a pilot phase will be undertaken to determine the most effective way to present and map the data. This phase will involve experimenting with different styles of data visualisation to establish which method best conveys the information to the reader in a clear and meaningful way. By employing a combination of presentation methods, we aim to ensure that the data is accessible to a broad audience, including healthcare professionals, individuals with lay expertise, and stakeholders with an interest in the support systems for individuals with neurodegenerative conditions.
