Item Assessment of Interest and Resources Needed for the Development of Scalable Healthcare Professionals Facilitated Strategies to Diversify Alzheimer’s Disease Research Participation(Wiley, 2025-01-09) Parker, Monica W.; Glover, Crystal M.; Johnson, David K.; Arce Rentería, Miguel; Biber, Sarah A.; Wang, Sophia; Psychiatry, School of MedicineBackground: Increasing underrepresented racial and ethnic minority group (URG) participation in early‐stage Alzheimer’s disease and related dementias (ADRD) research is critical to inclusive characterization of underlying pathology and testing of disease‐modifying treatments. One promising recruitment strategy to accelerate URG participation is for healthcare professionals (HCPs) to facilitate referrals. The use of HCP‐facilitated recruitment strategies across the Alzheimer’s Disease Research Center (ADRC) network, a major referral source for ADRD multisite observational and clinical trials, has not been examined. We hypothesized that there would be interest in the development of scalable HCP‐facilitated recruitment strategies to accelerate URG participation across the ADRC network. Methods: We emailed Outreach, Recruitment and Engagement (ORE) Cores within the NIA‐funded ADRC network to complete a web‐based REDCap™ survey on their current HCP‐facilitated recruitment strategies for URG participants, resources enhancing use of these strategies, and their interest in strategy development. We conducted descriptive statistics using SPSS 29.0. Results: Out of 37 ADRCs, 27 (73.0%) completed the survey. Although the majority of ADRCs (66.7%, N = 18) reported HCPs referring URG participants (Table 1), they mostly relied on HCP faculty based at the ADRC (48.1%, N = 13) or the ADRC affiliated academic medical center (51.9%, N = 14) (Table 2). Nearly all (92.5%, N = 25) ORE Cores expressed interest in participating in or learning more about future efforts to develop HCP‐facilitated recruitment strategies for increasing URG participation. Resources which would increase use of HCP‐facilitated strategies for URG referrals included guidance on outreach and engagement strategies (70.4%, N = 19), culturally tailored resources for HCPs to refer participants (59.3%, N = 16), technology and informatic recruitment strategies (63.0%, N = 17), and staff effort (63.0%, N = 17) (Table 3). Conclusions: Our survey identified key opportunities to develop novel scalable HCP‐facilitated recruitment strategies to accelerate URG participation. Although most ORE Cores expressed interest in expanding their HCP‐facilitated recruitment strategies to have more inclusive research participation, there is need for both higher‐level strategic guidance and ready‐to‐use resources to implement these strategies. Future studies will need to develop and test scalable HCP‐facilitated strategies and resources to systematically accelerate URG research participation.Item The Association of Late Life Cognitive Activity with Healthcare and Financial Decision Making in Community-Dwelling, Non-Demented Older Adults(Elsevier, 2021) Glover, Crystal M.; Yu, Lei; Stewart, Christopher C.; Wilson, Robert S.; Bennett, David A.; Boyle, Patricia A.; Neurology, School of MedicineObjective: The purpose of this study was to test the hypothesis that late life cognitive activity is associated with decision-making in older adults and to examine whether this association varies by level of cognitive function. Design: This study employed a cross-sectional design. Setting: All data were collected in participants' community-based residences. Participants: Participants were 1,084 older adults (mean age = 81.05 years, standard deviation = 7.53) without dementia (median Mini-Mental State Examination score = 29, interquartile range = 27.86-30.00). Measurements: Participants completed assessments of late life cognitive activity, cognitive function, and decision-making. We used linear regression models to examine the associations of late life cognitive activity and cognitive function with decision-making. Results: In a regression model adjusted for age, gender, and education, more frequent late life cognitive activity was associated with better decision-making, as was higher cognitive function. Furthermore, in an additional model that included the interaction of late life cognitive activity and cognitive function, the interaction was significant, such that late life cognitive activity was most strongly associated with decision-making among participants with lower levels of cognitive function. Conclusion: Frequent engagement in late life cognitive activity may help maintain decision-making among older persons, particularly among those with lower levels of cognitive function.Item Childhood Socioeconomic Status Interacts with Cognitive Function to Impact Scam Susceptibility Among Community-Dwelling Older Adults(Taylor & Francis, 2023) Glover, Crystal M.; Yu, Lei; Stewart, Christopher C.; Wilson, Robert S.; Bennett, David A.; Lamar, Melissa; Boyle, Patricia A.; Neurology, School of MedicineObjectives: We examined whether childhood socioeconomic status (SES) is related to scam susceptibility in old age and tested the hypothesis that childhood SES interacts with cognitive function to impact scam susceptibility. Methods: This study employed a cross-sectional design. All data were collected in participants' community-based residences. Participants were 1071 older adults (mean age = 81.05 years, SD = 7.53) without dementia (median MMSE score = 28.29, IQR = 27.86-30.00). Participants completed assessments of childhood SES, cognitive function, and scam susceptibility. We used linear regression models to examine the associations of childhood SES and cognitive function with scam susceptibility. Results: In a regression model adjusted for age, gender, and education, poorer cognitive function was associated with higher scam susceptibility, but childhood SES was not. However, in an additional model that included the interaction of childhood SES and cognitive function, the interaction was significant, such that lower childhood SES was associated with higher scam susceptibility among participants with lower cognitive function. Conclusion: Lower childhood SES is associated with higher scam susceptibility among older adults with lower levels of cognitive function. Thus, older adults who experienced limited resources in childhood and have lower cognitive function may represent a specific group for interventions to increase scam awareness and prevent financial exploitation.Item Health and Financial Literacy and the Acquisition of COVID-19 Knowledge in Older Adults(Sage, 2025) Stewart, Christopher C.; Yu, Lei; Byrne, Maeve; Glover, Crystal M.; Bennett, David A.; Boyle, Patricia A.; Neurology, School of MedicineKnowledge about COVID-19 enters into many aspects of decision making, especially for older people who are at increased risk of severe disease or death. Yet little is known about the resources that supported older people's uptake of COVID-19 knowledge. Here, we hypothesized that higher pre-pandemic health and financial literacy was associated with higher COVID-19 knowledge. Participants were 434 community-based older people without dementia. COVID-19 knowledge was assessed via a 5-item measure, and health and financial literacy was assessed via a 32-item measure. In an ordinal regression model adjusted for age, gender, and education, higher literacy was associated with higher COVID-19 knowledge (p < .0001), and this association persisted after further adjusting for robust measures of global cognition or one of five specific cognitive domains (all p's ≤ .0001). These findings suggest that literacy plays a key role in supporting older people's acquisition of impactful knowledge in the real world.Item Loneliness Interacts With Cognition in Relation to Healthcare and Financial Decision Making Among Community-Dwelling Older Adults(Oxford University Press, 2020-11-23) Stewart, Christopher C.; Yu, Lei; Glover, Crystal M.; Mottola, Gary; Bennett, David A.; Wilson, Robert S.; Boyle, Patricia A.; Neurology, School of MedicineBackground and objectives: Cognition is a known determinant of healthcare and financial decision making in old age. Social vulnerabilities also might play a role in such decisions; however, the evidence for this is less clear. Here, we examined the association of loneliness with decision making and tested the hypothesis that loneliness is associated with decision making via its interaction with global cognition. Research design and methods: Participants were 1,121 nondemented older adults from the Rush Memory and Aging Project. Healthcare and financial decision making was assessed via a performance-based measure; loneliness was assessed via the De Jong Gierveld Loneliness Scale; and cognition was assessed via a 19-test neuropsychological battery. Results: In a regression model adjusted for age, sex, and education, global cognition was associated with decision making (B = 2.43, SE = 0.14, p < .001) but loneliness was not (B = -0.04, SE = 0.11, p = .72). However, in a model including the interaction of loneliness with global cognition, the interaction was significant (B = 0.44, SE = 0.20, p = .03), such that the detrimental effect of loneliness on decision making was stronger when cognition was low. In secondary analyses examining the interaction of loneliness with 5 specific cognitive domains, the interaction between loneliness and working memory with decision making was significant (B = 0.35, SE = 0.15, p = .02). Discussion and implications: Our results suggest that loneliness compromises healthcare and financial decision making among older adults with lower global cognition and, more specifically, lower working memory.Item Perspective on the "African American participation in Alzheimer disease research: Effective strategies" workshop, 2018(Wiley, 2020-12) Denny, Andrea; Streitz, Marissa; Stock, Kristin; Balls-Berry, Joyce E.; Barnes, Lisa L.; Byrd, Goldie S.; Croff, Raina; Gao, Sujuan; Glover, Crystal M.; Hendrie, Hugh C.; Hu, William T.; Manly, Jennifer J.; Moulder, Krista L.; Stark, Susan; Thomas, Stephen B.; Whitmer, Rachel; Wong, Roger; Morris, John C.; Lingler, Jennifer H.; Psychiatry, School of MedicineThe Washington University School of Medicine Knight Alzheimer Disease Research Center's "African American Participation in Alzheimer Disease Research: Effective Strategies" Workshop convened to address a major limitation of the ongoing scientific progress regarding Alzheimer's disease and related dementias (ADRD): participants in most ADRD research programs overwhelmingly have been limited to non-Hispanic white persons, thus precluding knowledge as to how ADRD may be represented in non-white individuals. Factors that may contribute to successful recruitment and retention of African Americans into ADRD research were discussed and organized into actionable next steps as described within this report.Item Psychological Wellbeing Relates to Healthcare and Financial Decision Making in a Study of Predominantly White Older Adults(Sage, 2023) Glover, Crystal M.; Stewart, Christopher C.; Yu, Lei; Wilson, Robert S.; Lamar, Melissa; Bennett, David A.; Boyle, Patricia A.; Neurology, School of MedicineThe purpose of this study was to test the hypotheses that psychological well-being is associated with healthcare and financial decision making in older adults and that this association varies by the level of cognitive function. Participants were 1082 older adults (97% non-Latino White; 76% women; mean age = 81.04 years; SD = 7.53) without dementia (median MMSE score = 29.00, IQR = 27.86-30.00). In a regression model adjusted for age, gender, and years of education, higher levels of psychological well-being were associated with better decision making (estimate = 0.39, standard error [SE] = 0.11, p < .001), as was better cognitive function (estimate = 2.37, SE = 0.14, p < .0001). In an additional model, an interaction of psychological well-being and cognitive function was significant (estimate = -0.68, SE = 0.20, p < .001), such that higher levels of psychological well-being were most beneficial for decision making among participants with lower levels of cognitive function. Higher levels of psychological well-being may help sustain decision making among older persons, particularly those with lower levels of cognitive function.Item Purpose in Life and Cognition Interact to Impact Healthcare and Financial Decision Making in Old Age(Sage, 2022) Stewart, Christopher C.; Yu, Lei; Glover, Crystal M.; Bennett, David A.; Wilson, Robert S.; Boyle, Patricia A.; Neurology, School of MedicineObjectives: Little is known about the contribution of positive psychological factors, such as purpose in life, to healthcare and financial decision making in aging. Here, we examined the relationship between purpose and decision making and tested the hypothesis that purpose benefits decision making, particularly when cognition is limited. Methods: Participants were 1081 community-based older adults without dementia. Healthcare and financial decision making was measured via a 12-item performance-based instrument. Purpose was measured via a 10-item scale. Results: In a linear regression model adjusted for age, sex, and education, higher global cognition was associated with better performance on the decision making measure, as expected. Purpose was not directly related to decision making. However, the interaction of purpose with cognition was significant, such that greater purpose was associated with better decision making among persons with lower cognition. Discussion: Purpose in life may promote better decision making among older adults with lower cognition.Item Referral Sources Across Racial and Ethnic Groups at Alzheimer’s Disease Research Centers(IOS Press, 2024) Chan, Carol K.; Lane, Kathleen A.; Gao, Sujuan; Adeoye-Olatunde, Omolola A.; Biber, Sarah; Glover, Crystal M.; Johnson, David K.; Risacher, Shannon L.; Saykin, Andrew J.; Wang, Sophia; Radiology and Imaging Sciences, School of MedicineBackground: Despite the need to increase engagement of underrepresented groups (URG) in Alzheimer's disease and related dementias (ADRD) studies, enrollment remains low. Objective: Compare referral sources across racial and ethnic groups among participants enrolled in ADRC studies. Methods: Data for this cross-sectional secondary analysis were extracted from the National Alzheimer's Coordinating Center Uniform Data Set. We performed mixed effects logistic regression models using generalized estimating equations for professional referral versus non-professional referral by racial and ethnic group, adjusted for age, gender, education, visit year, and Clinical Dementia Rating scale (CDR) with a random effect for study site. Results: Included in the analysis were 48,330 participants across 46 ADRCs (mean [SD] age, 71.3 [10.5] years; 20,767 female [57%]; 4,138 Hispanic [8.6%]; 1,392 non-Hispanic Asian [2.9%]; 6,766 non-Hispanic Black [14%] individuals; and 676 individuals [1.4%] of other races. Non-Hispanic Black and Asian participants had lower odds of being referred by a professional contact compared to non-Hispanic White participants (Black: adjusted OR = 0.61, 95% CI = 0.44-0.86, p = 0.005; Asian: adjusted OR = 0.65, 95% CI, p = 0.004). In participants who had completed an MRI, there was no significant difference in referral source across ethnic and racial groups. Conclusions: Further studies are needed to better understand the systemic and structural factors that contribute to differences in referral sources and disparities in recruitment of URG into ADRD studies.Item Susceptibility to Scams in Older Black and White Adults(Frontiers Media, 2021-07-12) Han, S. Duke; Barnes, Lisa L.; Leurgans, Sue; Yu, Lei; Stewart, Christopher C.; Lamar, Melissa; Glover, Crystal M.; Bennett, David A.; Boyle, Patricia A; Neurology, School of MedicinePrevious reports on racial differences in scam susceptibility have yielded mixed findings, and few studies have examined reasons for any observed race differences. Older Black and White participants without dementia (N = 592) from the Minority Aging Research Study and the Rush Memory and Aging Project who completed a susceptibility to scam questionnaire and other measures were matched according to age, education, sex, and global cognition using Mahalanobis distance. In adjusted models, older Black adults were less susceptible to scams than older White adults (Beta = −0.2496, SE = 0.0649, p = 0.0001). Contextual factors did not mediate and affective factors did not moderate this association. Analyses of specific items revealed Black adults had greater knowledge of scam targeting of older adults and were less likely to pick up the phone for unidentified callers. Older Black adults are less susceptible to scams than demographically-matched older White adults, although the reasons remain unknown.
