Insights From African American Older Adults on Brain Health Research Engagement: "Need to See the Need"

The use of photovoice to explore the physical disability experience in older adults with mild cognitive impairment/early dementia

Although co-occurring cognitive impairment and physical disability in older adults is common, there is little understanding of how this group perceives their ability to do their daily activities. This study used photovoice to explore how older adults with MCI/early dementia and physical disability without and with care partners (dyads) perceive challenges with their daily activities. Photovoice is a visual research methodology to capture participants' insight on aspects of their daily lives. No known studies have taken this approach to explore the experiences of older adults with MCI/early dementia and co-occurring physical disability. We used a cross-sectional, exploratory research design to understand participants' (n = 12) experiences in their home environment. Photos and participant thoughts on the photos were categorized based on the Blackfoot Breath of Life Theory and the Hierarchy Model of Needs in Dementia, an adaptation of Maslow's Model. Notable findings included: awareness of physical/cognitive difficulties by older adults, solutions for ADL difficulty in persons with MCI/early dementia, care partners' difficulty recognizing pain without the presence of severe emotional or physical responses, reducing mood severity, and self-esteem needs met with structured, memory-issue adapted, meaningful activities. Older adults with co-occurring physical disability and MCI/early dementia identified both physiological and psychological needs despite challenges impacting their cognition. Photovoice evoked daily situations of these individuals and revealed the importance of developing individualized intervention elements for older adults with dementia and physical disability.

Are We Talking About the Same Thing? Black/African Americans' Response to the BRFSS Cognitive Decline and Caregiver Modules

The Behavioral Risk Factor Surveillance System (BRFSS) is a randomized national U.S. telephone survey administered by state health departments. This study aimed to identify how Black/African Americans understand BRFSS caregiver and cognitive decline surveys and terminology to inform health messaging that centers the Black/African American experience. In focus groups, BRFSS surveys were administered to Black/African Americans (n = 30) aged ≥ 45 in Oregon. Participants were asked how they interpreted BRFSS terms 'memory loss' and 'confusion,' how these terms related to Alzheimer's and dementia, and about caregiving and cognitive decline experiences. The culturally responsive Africana Worldview guided interpretation, which centers the Black/African American experience and individuals within interdependent relationships and community identity when explaining behaviors of people from the African diaspora. BRFSS survey responses differed from focus group responses to the same questions. Two participants reported providing care in the past two years on the survey; in discussions, 21 participants reported providing care in the past two years. Interpretations of BRFSS terminology varied greatly. Differences between age-related cognitive changes, dementia and Alzheimer's disease were unclear. Cognitive decline was largely understood in terms of identity loss and relationship changes with the affected individual, and how that individual's relationship changed within community. Caution is advised when using BRFSS data to frame messaging because key cognitive health terms are not universally understood. Messaging that apply the Africana Worldview centralizes relationships and community rather than impact on individual's day-to-day activities, may be more effective for Black/African Americans and for other groups with different cultural and life experiences.

Cognitive prescriptions for reducing dementia risk factors among Black/African Americans: feasibility, acceptability, and preliminary efficacy

OBJECTIVES

Black/African Americans (B/AAs) have double the risk of Alzheimer's disease and related dementia than Whites, which is largely driven by health behaviors. This study examined the feasibility, acceptability, and preliminary efficacy of a pilot randomized clinical trial of an individualized multidomain health behavior intervention among middle-aged and older B/AAs (dubbed Cognitive Prescriptions [CogRx]).

DESIGN

Thirty-nine community-dwelling B/AA participants aged 45-65 without significant cognitive impairment were randomized to one of three groups: CogRx, Psychoeducation, or no-contact control. The Psychoeducation and CogRx groups received material on dementia prevalence, prognosis, and risk factors, while the CogRx group additionally received information on their risk factor profile across the five CogRx domains (physical, cognitive, and social activity, diet, sleep). This information was used for developing tailored 3-month goals in their suboptimal areas.

RESULTS

The CogRx program had high retention (all 13 CogRx participants completed the 3-month program and 97% of the full sample completed at least 1 follow-up) and was well-received as exhibited by qualitative and quantitative feedback. Themes identified in the positive feedback provided by participants on the program included: increased knowledge, goal-setting, personalization, and motivation. The COVID-19 pandemic was a consistent theme that emerged regarding barriers of adherence to the program. All three groups improved on dementia knowledge, with the largest effects observed in CogRx and Psychoeducation groups. Increases in cognitive, physical, and overall leisure activities favored the CogRx group, whereas improvements in sleep outcomes favored Psychoeducation and CogRx groups as compared to the control group.

CONCLUSION

The CogRx program demonstrated feasibility, acceptability, and preliminary efficacy in increasing dementia knowledge and targeted health behaviors. Further refinement and testing of the implementation and effectiveness of similar person-centered dementia prevention approaches are needed on a larger scale in diverse populations. Such findings may have implications for clinical and public health recommendations.

Enablers and barriers to engaging under-served groups in research: Survey of the United Kingdom research professional's views

Background

There is a known lack of diversity in research participant populations. This impacts on the generalisability of findings and affects clinician prescribing. In the United Kingdom the research community defines those who are underrepresented as under-served. They are commonly those affected by health inequality and disparity. The notion of under-served is complex, with numerous papers identifying multiple factors that contribute to being under-served and in turn suggesting many strategies to improve engagement.

Methods

Research professionals in the UK were invited to complete an online survey. The broad aim was to explore their views on under-served groups. The findings were analysed using statistical and qualitative methods to identify enablers and barriers to engaging the under-served. Descriptive statistics were utilised with associations compared univariately by chi-square test and logistic regression for multivariable analysis.

Results

A total of 945 completed responses were received. Those identified as under-served in this study reflected the previous body of works with a broader descriptor of ethnic and cultural minorities and the addition of adolescents and young adults. Language and literacy skills had the most impact on being under-served. Only 13% of respondents said they felt equipped to meet the needs of the under-served. The main strategy to increase diversity was community engagement and movement of research delivery into the community. The barriers were funding and time. Training needs identified were linked to community engagement, cultural competence and consent processes.

Conclusions

The UK findings from research professionals reflected the previous literature. Adolescents and young people were added to those identified as under-served. Enablers included community outreach and improvement to communication. Barriers were time, funding, organisational processes and lack of focus. Issues were identified with translation and interpretation services. Training requirements focus on methodologies and methods to engage and the consent processes of those from under-served groups.

An innovative approach to recruiting participants for dementia research: primary care and researcher perspectives

Aim: To describe clinician and researcher perceptions of a new, patient preference focused approach to recruiting patients for research from primary care-based memory clinics. Methods: Memory clinic clinicians completed a survey and key informants completed an individual interview to gather their perceptions of this new program. Results: The majority of clinicians were 'satisfied' or 'very satisfied' with this recruitment approach and indicated that this approach would have minimal negative impact on patient care or create conflict of interest. Key informants valued the program for its patient-centred approach, the integration of research into care and potential for increased recruitment. Discussion: These findings are suggestive of support for this recruitment approach. Pilot testing will inform feasibility, effectiveness and process improvements.

Understanding Barriers and Facilitators to Signing Up for a Mobile-Responsive Registry to Recruit Healthy Volunteers and Members of Underrepresented Communities for Alzheimer's Disease Prevention Studies

BACKGROUND

Alzheimer's disease (AD) disproportionately affects Black/African American and Hispanic/Latino adults, yet they are underrepresented in AD studies. Recruitment challenges for these populations limit generalizability of findings.

OBJECTIVES

This study explores barriers and facilitators to signing up for an AD participant recruitment registry website intended to optimize recruitment of these adults. The registry is geared toward recruitment on smartphones and tablets (mobile devices), as research suggests that mobile-first approaches may be more successful within these populations.

DESIGN

In 2020, we conducted four focus groups (n = 39) and an online survey (n = 1010) with Black/African American and Hispanic/Latino adults. The survey also included Whites as a comparison group.

SETTING

Focus groups were in-person at research facilities in New Orleans, Louisiana, and Los Angeles, California. The online survey was distributed by a survey panel company to participants nationwide.

PARTICIPANTS

Black/African American (n = 360), Hispanic/Latino (n = 359), or White (n = 330) individuals, 45-75 years old, who self-reported not having mild cognitive impairment (MCI), dementia, or AD.

MEASUREMENTS

Barriers and facilitators explored in the focus groups and survey were related to health and AD (e.g., AD-related concerns and past participation/willingness to participate in health or AD studies); current use of mobile devices (e.g., comfort using devices and receptivity to the AD recruitment registry); and participant characteristics and beliefs (e.g., demographics, health literacy level, and trust in government and the scientific community).

RESULTS

The focus groups and survey revealed similar findings. Participants commonly use mobile devices to go online and perform health-related activities. They were aware of AD, expressed concerns with developing it, and were willing to participate in AD-related studies (motivated by personal connection to AD, altruism, and compensation). When presented with the AD recruitment registry, most provided positive feedback (e.g., easy to use and informative) and shared an interest in joining. Barriers to joining the registry with a mobile device included complex or multistep enrollment processes, beliefs that studies are primarily for those with a specific disease, and confusion about how studies can prevent AD among those low-risk for AD. The focus groups also revealed that Black/African American participants expressed more hesitation than Hispanic/Latinos in joining the registry due to greater distrust in the government and scientific community.

CONCLUSIONS

Recruiting more Black/African American and Hispanic/Latino participants into AD studies is vitally important. This mixed methods study suggests that adults in these underrepresented groups are motivated to prevent AD and willing to sign up for an AD participant recruitment registry using mobile devices. Most barriers to joining a registry can be addressed through slight modifications to the registry's design and functionality and by adding content. These findings can help enhance the appeal of joining AD recruitment registries to ultimately enroll more diverse, representative groups of participants and increase the generalizability of AD study findings.

Mechanisms by which Cultural-Centric Narrative Influences Interest in ADRD Research Among African American Adults

BACKGROUND AND OBJECTIVES

Insufficient ethnoracial diversity is a pervasive challenge in Alzheimer's disease (AD) research. The Recruitment Innovations for Diversity Enhancement (RIDE) is grounded in the premise that culturally informed narratives of research participation can inspire individuals from a given culture-sharing group to consider research enrollment. This study examines factors associated with interest in AD research among Black or African American adults following exposure to RIDE narrative campaign materials.

RESEARCH DESIGN AND METHODS

A community-based sample of 500 Black or African American adults viewed RIDE narrative materials online and completed a survey of perceptions about research, AD risk, and likelihood of enrolling in AD research. Logistic regression examined predictors and mediators of self-reported likelihood of participating in AD research.

RESULTS

Most (72%) participants reported interest in being contacted for AD research opportunities. After controlling for key variables, prior experience with clinical research and trust in medical researchers emerged as independent predictors of likelihood of enrolling in AD research. Perceived burden of AD research partially mediated the effects of prior research experience and trust on likelihood of enrollment. Perceived benefits of AD research also played a mediating role, accounting for over one third of the effect of trust on likelihood of enrollment.

DISCUSSION AND IMPLICATIONS

This study advances the field's understanding of how narrative may function to enhance diversity in AD research. Findings suggest that participant narratives should address experiences regarding the burdens and potential benefits of AD research participation as these factors may influence decisions leading to subsequent research enrollment.

Feasibility and Acceptability of a Dietary Intervention to Reduce Salt Intake and Increase High-Nitrate Vegetable Consumption in Malaysian Middle-Aged and Older Adults with Elevated Blood Pressure: Findings from the DePEC-Nutrition Trial

The DePEC-Nutrition trial is a complex dietary and behavioural intervention of salt intake reduction combined with increased high-nitrate vegetable consumption among Malaysian middle-aged and older adults with elevated blood pressure. This study aimed to assess the feasibility and acceptability of the trial. Participants were recruited from the South East Asia Community Observatory (SEACO) database and randomised into one of four groups: (1) low salt; (2) high-nitrate vegetable; (3) combined high-nitrate vegetable and low salt; and (4) control. The intervention included a combination of group counselling sessions, information booklets, reinforcement videos and text messages to modify dietary behaviour. The primary outcomes evaluated were the measures of feasibility and acceptability of (1) recruitment, follow-up attendance and retention; (2) data collection procedures and clinical outcome measures; and (3) individual and combined multi-modal dietary interventions. A total of 74 participants were recruited, and the 10-month retention rate was 73%. Data collection procedures were acceptable with minimal missing data. All intervention strategies were feasible and acceptable, with group counselling being the most acceptable strategy. This study provides important insights into improving the screening process of participants, facilitating their access to the research facilities and refining the measurement protocols and dietary recommendations, which are instrumental in formulating the design of a full-scale definitive DePEC-Nutrition trial.

Older adults' motivations to participate or not in epidemiological research. Qualitative inquiry on a study into dementia in Switzerland

INTRODUCTION

High participation in epidemiological studies is crucial for both external and internal validity. Because response rates have declined in recent years, there is an increasing need to understand the drivers and the barriers to research participation. This study aims to uncover the motivations in favour and against participation of older adults to an epidemiological study on health and dementia.

METHODS

Twenty-two older adults, who already took part to the preliminary phase of an epidemiological study in Switzerland, agreed to participate to semi-structured, face-to- face interviews. An experienced researcher carried out all interviews in a quiet place of choice of the interviewee either at their domicile or the university, between November 2019 and January 2020. The interviews were audio and video taped, transcribed verbatim, and thematically analysed by two independent researchers.

RESULTS

We identified three main themes for the motivations in favour of participation (i.e. personal, related to the outcomes of research, and altruistic motivations), and we highlighted subthemes for each theme (e.g. personal motivations: curiosity; civic engagement; interest in the topic; trust in science; everyone counts; openness; play the game). Motivations against participation reflected the first two themes, while there was no counterpart for altruistic motivations.

CONCLUSIONS

Our thematic analysis revealed that older adults hold specular motivations in favour and against participation to research. Studying jointly motivations in favour and against provides information for recruitment strategies and to overcome barriers to participation, respectively. Participatory action research can inform the design and conduction of and should precede epidemiological studies in older adults, and can potentially contribute to attain high response rates.
