Including ethnic minorities in dementia research: Recommendations from a scoping review

Recruitment, retention and reporting of variables related to ethnic diversity in randomised controlled trials: an umbrella review

OBJECTIVE

This umbrella review synthesises evidence on the methods used to recruit and retain ethnically diverse participants and report and analyse variables related to ethnic diversity in randomised controlled trials.

DESIGN

Umbrella review.

DATA SOURCES

Ovid MEDLINE, Ovid Embase, CINAHL, PsycINFO and Cochrane and Campbell Libraries for review papers published between 1 January 2010 and 13 May 2024.

ELIGIBILITY CRITERIA

English language systematic reviews focusing on inclusion and reporting of ethnicity variables. Methodological quality was assessed using the AMSTAR 2 tool.

RESULTS

Sixty-two systematic reviews were included. Findings point to limited representation and reporting of ethnic diversity in trials. Recruitment strategies commonly reported by the reviews were community engagement, advertisement, face-to-face recruitment, cultural targeting, clinical referral, community presentation, use of technology, incentives and research partnership with communities. Retention strategies highlighted by the reviews included frequent follow-ups on participants to check how they are doing in the study, provision of incentives, use of tailored approaches and culturally appropriate interventions. The findings point to a limited focus on the analysis of variables relevant to ethnic diversity in trials even when they are reported in trials.

CONCLUSION

Significant improvements are required in enhancing the recruitment and retention of ethnically diverse participants in trials as well as analysis and reporting of variables relating to diversity in clinical trials.

Understanding engagement in diet and dementia prevention research among British South Asians: a short report of findings from a patient and public involvement group

BACKGROUND

Dementia is a global public health challenge. Evidence suggests that individuals from South Asian communities are an at-risk group for dementia, partly as a result of early and cumulative exposure to known dementia risk factors, such as obesity and type 2 diabetes. There needs to be more culturally appropriate community engagement to increase awareness of dementia and identify better strategies to encourage participation in dementia-related research.

METHODS

We aimed to better understand the barriers and facilitators towards engaging with, and participating in, diet and dementia related research among British South Asians. This was achieved using a public and patient involvement (PPI) approach. A community-based, engagement event involving information sharing from experts and roundtable discussions with South Asian communities (n = 26 contributors) was held in June 2023 in Newcastle-upon-Tyne, UK. Collaboration from preidentified PPI representatives (n = 3) informed the content and structure of PPI activities, as well as recruitment. Data were synthesised using template analysis, a form of codebook thematic analysis. This involved deductively analysing data using relevant a priori themes, which were expanded upon, or modified, via inductive analysis.

RESULTS

The findings highlighted the importance of trust, representation and appreciation of cultural barriers as facilitators to engagement in diet and dementia risk reduction research. Consideration of language barriers, time constraints, social influences and how to embed community outreach activities were reported as driving factors to maximise participation.

CONCLUSIONS

This PPI work will inform the design and co-creation of a culturally adapted dietary intervention for brain health in accordance with the Medical Research Council and National Institute for Health and Care Research guidance for developing complex interventions.

Embodied leisure experiences of nature-based activities for people living with dementia

PURPOSE

This article adopts an embodiment lens to explore the individual leisure experiences of people living with dementia when engaging in nature-based pursuits. It focuses on how people living with dementia frame their everyday experiences of nature and how these are shaped by any cognitive challenges and/or other comorbidities affecting physical health.

DESIGN/METHODOLOGY/APPROACH

Taking a phenomenological research approach, we interviewed 15 people living with dementia and 15 family carers of people with dementia to explore how people with dementia engage with nature as a subjective leisure experience. We analysed their accounts using reflexive thematic analysis.

FINDINGS

The findings reveal how people living with dementia frame their experiences of nature-based pursuits through three interlinked themes of 'bodily feelings and emotions', 'sense of self and identity' and 'connectivity to others'.

ORIGINALITY/VALUE

The paper contributes to knowledge by examining through the lens of embodiment a neglected and overlooked dimension of everyday leisure: how nature is encountered, negotiated and enjoyed. The paper illustrates how nature and the outdoors may help people living with dementia to continue to enjoy prior leisure pursuits and thus achieve a degree of continuity in their everyday lives.

Dying with dementia in nursing homes: A population-based study of decedents and their families

BACKGROUND

Families play a critical role in end-of-life (EOL) care for nursing home (NH) residents with dementia. Despite the important role of family, little is known about the availability and characteristics of families of persons with dementia who die in NHs.

METHODS

This is a retrospective cohort study of 18,339 individuals 65 years and older with dementia who died in a Utah NH between 1998 and 2016, linked to their first-degree family (FDF) members (n = 52,566; spouses = 11.3%; children = 58.3%; siblings = 30.3%). Descriptive statistics, chi-square tests, and t-tests were used to describe the study cohort and their FDF members and to compare sociodemographic and death characteristics of NH decedents with (n = 14,398; 78.5%) and without FDF (n = 3941; 21.5%).

RESULTS

Compared with NH decedents with FDF, NH decedents with dementia without FDF members were more likely to be older (mean age 86.5 vs 85.5), female (70.5% vs 59.3%), non-White/Hispanic (9.9% vs 3.2%), divorced/separated/widowed (84.4% vs 61.1%), less educated (<12th grade; 42.2% vs 33.7%), have Medicare and Medicaid (20.8% vs 12.5%), and die in a rural/frontier NH (25.0% vs 23.4%). NH decedents who did not have FDF were also more likely to die from cancer (4.2% vs 3.9%), chronic obstructive pulmonary disease (COPD; 3.9% vs 2.5%), and dementia (40.5% vs 38.4%) and were less likely to have 2+ inpatient hospitalizations at EOL (13.9% vs 16.2%), compared with NH decedents with FDF.

CONCLUSIONS

Findings highlight differences in social determinants of health (e.g., sex, race, marital status, education, insurance, rurality) between NH decedents with dementia who do and do not have FDF-factors that may influence equity in EOL care. Understanding the role of family availability and familial characteristics on EOL care outcomes for NH residents with dementia is an important next step to informing NH dementia care interventions and health policies.

Assessing the impact of an online dementia awareness initiative co-created with and for English, Arabic and Vietnamese speaking communities: A case study

BACKGROUND

Awareness and understanding of dementia remain limited in ethnically diverse populations in multicultural societies due to culturally inappropriate and inaccessible information.

OBJECTIVE

To establish the impact, helpers and hinderers of an online multilingual dementia awareness initiative co-created with and for English, Arabic and Vietnamese speaking people.

DESIGN

A case study using mixed methods to assess the impact and implementation of an information session on dementia knowledge.

SETTING AND PARTICIPANTS

The study was conducted with English, Arabic and Vietnamese speaking individuals in Canterbury-Bankstown, Australia.

INTERVENTION STUDIED

A dementia alliance co-created an online multilingual dementia information session, which was delivered synchronously in English, Arabic and Vietnamese by trained facilitators.

MAIN OUTCOME MEASURES

In-session group discussions, quizzes and a postsession survey assessed the impact on dementia knowledge. A postimplementation focus group explored the factors that helped and hindered the initiative.

RESULTS

The online dementia information session successfully supported participants understanding of dementia causes, impacts and care strategies. The initiative was hindered by competing priorities and limited accessibility to target audiences, while it was helped by the support of an established organisation and feedback mechanisms.

DISCUSSION

Ongoing dementia education and awareness-raising campaigns that are culturally sensitive are needed in communities to promote dementia literacy and help-seeking.

CONCLUSIONS

An online multilingual dementia information session can be an effective way to improve dementia literacy and advocate for change in multicultural communities.

PATIENT OR PUBLIC CONTRIBUTION

English, Arabic and Vietnamese speaking members of the Canterbury Bankstown Dementia Alliance participated in the co-creation and evaluation of this initiative.

Chinese-Australian carers' perceived needs and preferences in planning to embed an iSupport for Dementia program in aged care services

OBJECTIVE

To assess Chinese-Australian carers' needs and preferences through co-design strategies with stakeholders to embed an evidence-based iSupport for Dementia program into routine community aged care services in Chinese ethno-specific aged care organisations.

METHODS

A cross-sectional survey was conducted from July to August 2022 in three Chinese ethno-specific aged care organisations in Australia. We applied a univariate analysis to test variables associated with carers' needs and preferences when embedding the iSupport for Dementia program into routine practice among community aged care services.

RESULTS

A total of 101 carers completed the survey. Most carers in our study preferred the iSupport program to be provided in their first language, have a program facilitator to lead the program and would like to interact with peers in the program. Most carers indicated that they are willing to pay for the iSupport program using the budget allocated to their home care package. Younger carers (younger than 65 years), and adult children's carers are more likely to use the web-based iSupport manual and invite their family members to the program compared to those older than 65 years. Other demographic characteristics had no significant association with their needs and preferences.

CONCLUSIONS

Chinese-Australian carers' perceived needs and preferences in this study will inform the implementation of a culturally tailored iSupport program to be embedded in community aged care services provided by Chinese ethno-specific aged care organisations. Findings will also inform culturally and linguistically congruent iSupport programs for carers from other culturally and linguistically diverse communities in Australia.

Patient and public involvement and engagement with underserved communities in dementia research: Reporting on a partnership to co-design a website for postdiagnostic dementia support

INTRODUCTION

Despite the advancements in Patient and Public Involvement and Engagement (PPIE), the voices of traditionally underserved groups are still poorly reflected in dementia research. This study aimed to report on a PPIE partnership between academics and members of the public from underserved communities to co-design Forward with Dementia-Social Care, a resource and information website supporting people receiving a dementia diagnosis.

METHODS

The PPIE partnership was set up in four stages: 1-identifying communities that have been under-represented from PPIE in dementia research; 2-recruiting PPIE partners from these communities; 3-supporting PPIE partners to become confident to undertake their research roles and 4-undertaking research co-design activities in an equitable fashion.

RESULTS

To address under-representation from PPIE in dementia research we recruited seven PPIE partners from Black, Asian and other minority ethnic groups; lesbian, gay, bisexual, transgender, queer+ communities; remote/rural area; religious minorities and partners living with rare forms of dementia. The partners met regularly throughout the project to oversee new sections for the study website, refine existing content and promote the website within their communities.

CONCLUSION

Strategies can be used to successfully recruit and involve PPIE partners from underserved communities in co-design activities. These include networking with community leaders, developing terms of reference, setting out 'rules of engagement', and investing adequate resources and time for accessible and equitable involvement. These efforts facilitate the co-design of research outputs that reflect the diversity and complexity of UK contemporary society.

PATIENT OR PUBLIC CONTRIBUTION

This study received support from seven members of the public with lived experience of dementia from communities that have been traditionally underserved in dementia research. These seven members of the public undertook the role of partners in the study. They all equally contributed to the study design, recruitment of participants, development and revision of topic guides for the interviews and development of the website. Three of these partners were also co-authors of this paper. On top of the activities shared with the other partners, they contributed to write independently of the academic team the section in this paper titled 'Partners' experiences, benefits and challenges of the partnership'. Further, they provided input in other sections of the paper on a par with the other (academic) co-authors.

Nonpharmacological interventions in dementia and diversity of samples: A scoping review

BACKGROUND

A public health priority is the increasing number of people with dementia (PwD), and nonpharmacological interventions (NPIs) might offer support. We sought to synthesize types of NPIs tested among PwD and explore sample characteristics.

METHODS

This study was a scoping literature review. Eligible articles were identified using the search terms "nonpharmacological intervention" and "dementia".

RESULTS

36 articles were included. Psychosocial NPIs were implemented the most (n=24) and music-based interventions were found to be the most effective. Gender, race, and ethnicity were not consistently reported (n=30, n=24, and n=6, respectively). White PwD had higher representation, with only 62.5% of studies including Black participants and 25% including Hispanic/Latino participants. Women made up a majority (>50%) of the sample in a greater number of studies (n=20).

CONCLUSION

Findings suggest that future studies need to be intentional about improving diversity of the sample, particularly with respect to including persons identifying as Black or Hispanic/Latino.

Attitudes and Preferences Towards Screening for Dementia with a Focus on Ethnic Minority and Low Socio-Economic Groups: A Systematic Review of Research Studies Written in the English Language

Background

Increased understanding of dementia risk-reduction and early detection of Alzheimer's disease and related disorders has spurred interest in the identification of risks for dementia, underlying putative biologies, or dementia itself. Implementation of such approaches require acceptability to the public. Research prior to 2012 indicated limited acceptability for population dementia screening. The changing landscape of dementia prevention research may influence recent perceptions. Additionally, perspectives from underserved populations, such as ethnic minorities and low socio-economic groups, are lacking.

Objective

In this systematic review, we sought published studies since 2012 on attitudes and preferences of people with dementia, carers and the general public from ethnic minorities and low socio-economic groups regarding dementia screening.

Methods

This review was preregistered on PROSPERO (CRD42023384115) and followed PRISMA guidelines. Key search terms were entered into five databases. Articles were included if they focused on population or risk screening for dementia via primary/community care-based assessments, and which included majority ethnic minority or low socio-economic groups or discretely considered these groups in data analysis. Data were synthesized narratively.

Results

Seven studies reported perspectives of ethnic minorities regarding dementia screening; one study included people from low socio-economic groups. Results indicated that participants from ethnic minorities were willing to undergo dementia screening. Predictors of willingness included belief in benefits, desire to boost diversity, and to implement lifestyle changes. Unwillingness was associated with anxiety regarding results.

Conclusions

Although there seems to be high acceptability for screening in the studied groups, more research is necessary to explore the practical considerations for screening such as cultural and economic barriers, trust, and post-screening actions.

Breaking the barriers: overcoming dementia-related stigma in minority communities

Dementia is a global health concern that affects individuals irrespective of their cultural or linguistic backgrounds. However, research has long recognized the pronounced stigma associated with dementia, particularly within Culturally and Linguistically Diverse (CALD) communities. This article seeks to summarize the underlying factors contributing to the heightened levels of dementia stigma within CALD communities, through a review of the literature. Our examination shows that cultural beliefs, language barriers, limited awareness, and the impact of migration on perceptions of aging and cognitive decline are contributing factors. Consequently, our analysis highlights the need for tailored, culturally appropriate interventions aimed at mitigating stigma and enhancing dementia care within CALD populations. Our proposed solutions, built on a social-ecological approach, highlights the critical role of collaborative efforts involving policymakers, healthcare providers, community organizations, and CALD community members in fostering a more dementia-inclusive society. This perspective piece aims to shed light on the distinct challenges faced by CALD communities, while advocating for a holistic approach to redefine perceptions and care strategies tailored to these populations.

Development of an item pool for a patient reported outcome measure of resilience for people living with dementia

BACKGROUND AND OBJECTIVES

Policies to support people living with dementia increasingly focus on strengths-based approaches, highlighting the importance of building resilience. This research responds to the lack of a suitable resilience measure for people with dementia. It develops a pool of items to inform a new measure of resilience for this population.

METHODS

A conceptual model and associated data informed the item generation of the draft resilience measure. Regular meetings with professionals (n = 7) discussed response-scale formatting, content and face validity, leading to refinement and item reduction. Cognitive interviews with people living with dementia (n = 11) then examined the face and content validity of items and the suitability of response-scale formatting. These two phases informed subsequent revision and further item reduction of the resilience measure.

RESULTS

The first item generation exercise led to 140 items. These were independently assessed by the professionals and this refinement reduced the measure to 63 items across 7 domains of the conceptual model (psychological strengths; practical approaches for adapting to life with dementia; continuing with hobbies, interests and activities; strong relationships with family and friends; peer support and education; participating in community activities; the role of professional support services). Cognitive interviews explored the 63 items with people living with dementia. Detailed feedback led to items removed due to difficulty with (a) understanding (N = 7); (b) answering (n = 11); (c) low preference for that item (n = 6); and (d) presence of a preferred item within a cluster of similar questions (n = 4). Items were amended to enhance clarity/conciseness (n = 19) leading to a final 37-item pool.

CONCLUSION

Established methods for measurement development included the expertise of people with dementia and led to the generation of a set of items for a new resilience measure that were understandable and acceptable to this target population. This 37-item pool reflects the conceptual understanding of resilience in dementia as being derived across individual, community and societal level resources.

Changes in Depressive Symptoms of Korean American Dementia Caregivers After Attending the Savvy Caregiver Program: Preliminary Findings with a Pilot Sample

OBJECTIVES

Language accommodation is indispensable in making evidence-based interventions available and accessible to ethnic minorities with limited English proficiency. As part of the larger effort to culturally adapt the Savvy Caregiver Program for Korean American dementia caregivers, we first conducted linguistic adaptation, and the present study reports the preliminary findings on participants' changes in depressive Symptoms.

METHODS

The linguistically adapted program was delivered to two small groups of Korean American dementia caregivers (total n = 13) by two Savvy-certified Korean-speaking trainers. Participants' depressive symptoms were assessed at three time points (pre-intervention, immediate post-intervention, and 6-month follow-up).

RESULTS

Following the intervention, participants exhibited lowered depressive symptoms (t = 8.64, p < .001, Cohen's d = .89). This benefit was sustained at 6-month follow-up.

CONCLUSIONS

Findings suggest that the therapeutic benefit of the Savvy Caregiver Program could potentially be shared with linguistic minorities when delivered in their native language.

CLINICAL IMPLICATIONS

Although limited in its scope and nature, the pilot study with linguistic adaptation sheds light on efforts to close the gap in the evidence-based intervention delivery.

"Why involve older people in research?" Revisiting Alan Walker's earlier editorial based on recent experiences from the UserAge research programme

Posed 16 years ago in a much-cited editorial by gerontologist, Alan Walker, "Why involve older people in research?" is a question that has since inspired researchers in many countries and from diverse disciplines. In Sweden, researchers and older people have been collaborating in the 6-year UserAge research programme, focusing on user involvement in research on ageing and health, UserAge aims at contributing to an in-depth understanding of the challenges and benefits of user involvement in different phases of the research process. Approaching programme completion, the authors take the opportunity to dwell upon current reasons for and modes of user involvement in ageing research in light of the argument originally put forward by Alan Walker back in 2007.

The development of the Cognitive Assessment for Tagalog Speakers (CATS): A culturally and linguistically tailored test battery for Filipino Americans

INTRODUCTION

Filipino Americans are one of the largest Asian American and Pacific Islander (AAPI) populations in the United States (US). Previous studies suggest that Filipino Americans have one of the highest incidence rates of Alzheimer's disease and related dementias (ADRD) among AAPI subgroups. Despite the expected increase in Filipino Americans with ADRD, no studies to-date have validated neuropsychological measures in the United States for speakers of Tagalog, a major language spoken by Filipino Americans. A significant barrier to dementia care and diagnosis is the lack of linguistically and socioculturally appropriate cognitive tasks for Tagalog speakers. To address this need, we developed and piloted the Cognitive Assessment for Tagalog Speakers (CATS), the first neuropsychological battery for the detection of ADRD in Filipino American Tagalog speakers.

METHODS

Based on evidence-based neuropsychological batteries, we adapted and constructed de novo tasks to measure performance across 4 main cognitive domains: visual/verbal memory, visuospatial functioning, speech and language, and frontal/executive functioning. Tasks were developed with a team of bilingual English/Tagalog, bicultural Filipino American/Canadian experts, including a neurologist, speech-language pathologist, linguist, and neuropsychologist. We recruited Tagalog-speaking participants of age 50+ through social media advertisements and recruitment registries for this cross-sectional study. We present the CATS design and protocol.

RESULTS

To-date, the CATS battery has been administered to 26 healthy control participants (age 64.5 ± 7.8 years, 18F/8 M) at an academic institution in Northern California, United States. The development and administration of the CATS battery demonstrated its feasibility but also highlighted the need to consider the effects of bilingualism, language typology, and cultural factors in result interpretation.

DISCUSSION

The CATS battery provides a mechanism for cognitive assessment of Filipino Americans, a population that has been underrepresented in ADRD research. As we move toward the treatment and cure of ADRD, linguistically and socioculturally appropriate cognitive tests become even more important for equitable care.

Experiences of people with dementia and informal caregivers with post-diagnostic support: Data from the international COGNISANCE study

OBJECTIVES

The study aims to describe people with dementia and informal caregivers' respective experiences of support after diagnosis and compares these experiences. Additionally, we determine how people with dementia and informal caregivers who are satisfied with support differ from those dissatisfied.

METHODS

A cross-sectional survey study in Australia, Canada, the Netherlands, Poland, and United Kingdom was carried out to examine people with dementia and informal caregivers experience with support (satisfaction with information, access to care, health literacy, and confidence in ability to live well with dementia). The separate surveys contained closed questions. Analysis consisted of descriptive statistics and Chi-square tests.

RESULTS

Ninety people with dementia and 300 informal caregivers participated, and 69% of people with dementia and 67% of informal caregivers said support after diagnosis helped them deal more efficiently with their concerns. Up to one-third of people with dementia and informal caregivers were dissatisfied with information about management, prognosis, and strategies for living positively. Few people with dementia (22%) and informal caregivers (35%) received a care plan. People with dementia were more often satisfied with information, had more often confidence in their ability to live well with dementia, and were less often satisfied with access to care compared to informal caregivers. Informal caregivers who were satisfied with support were more satisfied with information and access to care compared to informal caregivers not satisfied with support.

CONCLUSIONS

Experience of dementia support can be improved and people with dementia and informal caregiver differ in their experiences of support.

Recruiting Socially Disconnected Latinos Caring for a Person with Alzheimer's Disease and Related Dementias During the COVID-19 Pandemic: Lessons Learned

OBJECTIVES

The purpose of this article is to present conceptual and methodological challenges to recruitment strategies in enrolling socially disconnected middle-aged and older Latino caregivers of a loved one with Alzheimer's disease and related dementias (ADRD).

METHODS

Middle-aged and older Latino ADRD caregivers were recruited into two early stage, intervention development studies during the COVID-19 pandemic via online or in-person methods. Recruitment criteria included Latino ADRD caregivers over the age of 40 reporting elevated loneliness on the UCLA 3-item Loneliness Scale (LS) during screening.

RESULTS

Middle-aged, Latino caregivers were recruited predominantly from online methods whereas older caregivers were mostly recruited from in-person methods. We report challenges identifying socially disconnected Latino caregivers using the UCLA 3-item LS.

CONCLUSIONS

Our findings support previously reported disparities in recruitment by age and language and suggest further methodological considerations to assess social disconnection among Latino caregivers. We discuss recommendations to overcome these challenges in future research.

CLINICAL IMPLICATIONS

Socially disconnected Latino ADRD caregivers have an elevated risk for poor mental health outcomes. Successful recruitment of this population in clinical research will ensure the development of targeted and culturally sensitive interventions to improve the mental health and overall well-being of this marginalized group.

Health equity considerations in pragmatic trials in Alzheimer's and dementia disease: Results from a methodological review

Introduction

To improve dementia care delivery for persons across all backgrounds, it is imperative that health equity is integrated into pragmatic trials.

Methods

We reviewed 62 pragmatic trials of people with dementia published 2014 to 2019. We assessed health equity in the objectives; design, conduct, analysis; and reporting using PROGRESS-Plus which stands for Place of residence, Race/ethnicity, Occupation, Gender/sex, Religion, Education, Socioeconomic status, Social capital, and other factors such as age and disability.

Results

Two (3.2%) trials incorporated equity considerations into their objectives; nine (14.5%) engaged with communities; 4 (6.5%) described steps to increase enrollment from equity-relevant groups. Almost all trials (59, 95.2%) assessed baseline balance for at least one PROGRESS-Plus characteristic, but only 10 (16.1%) presented subgroup analyses across such characteristics. Differential recruitment, attrition, implementation, adherence, and applicability across PROGRESS-Plus were seldom discussed.

Discussion

Ongoing and future pragmatic trials should more rigorously integrate equity considerations in their design, conduct, and reporting.

Highlights

Few pragmatic trials are explicitly designed to inform equity-relevant objectives.Few pragmatic trials take steps to increase enrollment from equity-relevant groups.Disaggregated results across equity-relevant groups are seldom reported.Adherence to existing tools (e.g., IMPACT Best Practices, CONSORT-Equity) is key.
