Long-term and short-term predictors of worries about getting Alzheimer's disease

Perceived Threat of Alzheimer's Disease and Related Dementias Among Chinese Family Caregivers of Older Adults with Cognitive Impairment

Perceived threat of Alzheimer's disease and related dementias (ADRD) has been found a widespread phenomenon in developed countries, but has not yet been fully explored in developing countries. Analyzing data from 300 family caregivers of older adults with cognitive impairment in China, this study found caregiver burden was positively associated with the perceived threat of ADRD, and this association was buffered by higher family income and longer caregiving time. To alleviate undue ADRD concerns, it suggests expanding respite care and community elder care beds, and initiating education programs on reducing unnecessary worries about developing ADRD.

Dementia is the second most feared condition among Australian health service consumers: results of a cross-sectional survey

Fear of disease may act as a barrier to screening or early diagnosis. This cross-sectional survey of 355 people attending outpatient clinics at one Australian hospital found that cancer (34%) and dementia (29%) were the most feared diseases. Participants aged 65 years and over feared dementia the most.

Validation of the Fear and Avoidance of Memory Loss scale in community-based older adults

Introduction

Alzheimer's disease and related dementias (ADRD) are among the most feared conditions. However, research around ADRD-specific fear and avoidance behaviors is lacking. Here, we validated a novel measure of fear and avoidance specific to memory loss, the Fear and Avoidance of Memory Loss (FAM) scale, and examined associations between fear avoidance and psychosocial functioning in older adults.

Methods

We assessed FAM Scale internal reliability and concurrent validity, and candidate subscales across two samples (total N = 813). We then examined associations between fear avoidance and memory performance, anxiety, depressive symptoms, sleep, social functioning, and quality of life.

Results

We identified two subscales: fear and avoidance, which yielded strong psychometric validity. Higher fear was associated with memory failures and sleep disturbance. Higher avoidance was associated with memory failures, poorer verbal memory, reduced social functioning, and quality of life.

Discussion

We present the first measure of fear avoidance specific to memory loss. We propose that targeting fear avoidance can promote ADRD risk reduction and resiliency.

Dementia literacy and worry among older Chinese Americans in Arizona: a comparison between 2013 and 2017

OBJECTIVES

This study examined the change in dementia literacy and dementia worry over a 5-year span among older Chinese Americans living in Arizona.

DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENT

This study used survey data collected among a purposive sample of 703 community-dwelling Chinese Americans aged 55 years or older living in the metropolitan areas of Phoenix, Arizona, from 2013 to 2017. The average age of participants was 73.1 (SD = 8.7) and 64.2% were female. Dementia literacy was measured by dementia knowledge (knowledge about Alzheimer's disease and related dementia) and dementia beliefs (biased attitude toward dementia). Dementia worry was measured by assessing participants' fear toward and concerns of developing dementia.

RESULTS

Regression analyses found dementia knowledge decreased (p < 0.05) and dementia beliefs remained unchanged (p > 0.05) from 2013 to 2017 among participants. Dementia worry only increased among those who lived alone. Significant correlates of dementia worry included low formal education level, depressive symptoms, and family conflict.

CONCLUSIONS

Public health education targeting older Chinese Americans should aim to enhance dementia knowledge and to rectify their biased attitudes toward dementia. Psychosocial education or counseling should be available to older Chinese Americans who present dementia worry, particularly for those who live alone. More studies using diverse study designs, such as a longitudinal design, are needed to examine change in dementia literacy and worry among this population.

Relationship between consistent subjective cognitive decline and occurrence of falls six months later

PURPOSE

To examine the association between consistent subjective cognitive decline and fall occurrence six months later.

METHOD

A cohort study was conducted at two time points in community-dwelling older adults. The first survey was conducted from May to July 2020 and the second from November 2020 to January 2021. Older adults without missing data who had not fallen during the past year were analyzed. The questionnaire included sociodemographic data, a questionnaire for medical checkup of older adults, and a frailty screening index. We divided the participants into three groups according to the occurrence of subjective cognitive decline (SCD): 1) no SCD (did not complain of SCD at both time points), 2) unstable SCD (complained of SCD once), and 3) consecutive SCD (consistently complained of SCD). Multiple logistic regression analysis was used to examine the association between fall occurrence and SCD. Fall occurrences were obtained from the second survey.

RESULTS

In total, 322 participants were included in the analysis. The numbers of patients with no SCD, unstable SCD, and consecutive SCD were 226 (70.2%), 61 (19.0%), and 35 (10.9%), respectively. In the second survey, the number of falls was 26 (8.1%). Multiple logistic regression analysis showed that consecutive SCD was associated with fall occurrence, even after adjusting for age, sex, comorbidity, cohabitants, and frailty status (OR:3.143, 95% CI:1.076-9.388); however, unstable SCD was not (OR:2.348, 95% CI:0.816-6.468).

CONCLUSION

Consistent complaints of SCD were associated with the occurrence of falls. We highlighted the importance of evaluating SCD over time when considering falls.

Profiles in Dementia-Related Anxiety: A Latent Profile Analysis

OBJECTIVES

Dementia-related anxiety (DRA) is the concern about current or future cognitive decline and potential diagnosis of Alzheimer's disease or related dementias (ADRD). Existing research suggests that DRA likely develops due to diverse reasons (e.g., family ADRD history, self-perceived risk, and health-related anxiety), and approaches to managing DRA likely differ as well (e.g., future planning). This study aimed to identify profiles in DRA.

METHOD

In a cross-sectional study, a convenience sample of U.S. adults ranging in age from 18 to 82 (N = 492, Mage = 49.25, standard deviation [SDage] = 15.43) completed online assessments of characteristics associated with DRA. Latent profile analysis was used to uncover distinct DRA profiles and promote understanding of individual characteristics associated with varying levels of DRA; multinomial regression assessed if the profiles are further distinguished by covariates.

RESULTS

The resulting four-profile model reveals profile differences are largely due to DRA, self-perceived ADRD risk, and preparedness for future care needs; health-related anxiety, age, ADRD exposure, and anticipated ADRD stigma contribute to profile differences as well. Profiles of the youngest and oldest groups reported the lowest and highest levels of preparedness for future care, along with the lowest DRA and self-perceived risk. Several covariates, particularly those assessing general psychological functioning, were also related to profile membership.

DISCUSSION

The resulting profiles point to several factors associated with elevated anxiety about ADRD, which do not fully match the risk factors for ADRD.

Comparisons of Dementia Knowledge and Attitudes among the Youth and Older Adults: Insights from the Construal Level Theory Perspective

Based on Construal Level Theory (CLT), the youth and older adults have different psychological distances towards dementia that may lead to different dementia knowledge and attitudes. A cross-sectional survey among 239 youth and 62 older adults using a two-step sampling approach in Macao aimed to examine the hypothesis. Results showed older adults had a higher score of dementia knowledge (F(1,299) = 45.692, p <0.001) but a lower score of dementia attitudes (F(1,299) = 161.887, p <0.001) compared to the youth. Age group explained the majority of the variances in the hierarchical multiple regressions for dementia knowledge (R2 = 0.178, F = 9.059, p < 0.001) and for dementia attitudes (R2 = 0.399, F = 24.233, p < 0.001), which are β = 0.47 and -0.56, respectively. Thus, the hypothesis was supported and revealed an interesting pattern of dementia knowledge and attitudes among the youth and older adults. From the CLT perspective, the study implies that reducing and bridging the psychological distance of dementia would probably be an effective strategy to increase dementia awareness among young people, and intergenerational programs may be a good option to increase community acceptance and support for people with dementia.

Factors Associated With Dementia Knowledge and Dementia Worry in the South Korean Elderly Population

OBJECTIVE

South Korea is one of the countries with a very fast aging rate, and the prevalence of dementia is rapidly increasing. However, there are relatively few studies pertaining to sociodemographic and physical health-related factors associated with dementia knowledge and dementia worry.

METHODS

This was a cross-sectional survey of a community in Seocho-gu, Seoul, Republic of Korea. Overall, 1,869 adults aged 60 years participated. Participants completed an online interview or face-to-face interview. Survey data comprised self-report questions including dementia knowledge, dementia worry, demographic, psychological, exercise, and cognitive activities. We conducted logistic regression analysis.

RESULTS

There was a significant positive association between dementia worry and knowledge. Family history of dementia, education, income, sleep problems, depressed mood and loss of volition, chronic diseases, and presence of a past job were associated with dementia knowledge or worry. Reading, art, or social cognitive activities had a significant positive association with dementia knowledge, and writing or musical cognitive activities had a negative association with dementia worry.

CONCLUSION

We found that people with more dementia knowledge and less dementia worry engaged more in cognitive activities that could prevent dementia. Public education should be planned to improve dementia knowledge and reduce dementia worry.

Fear about Alzheimer's disease among Israeli and German laypersons, persons with Mild Neurocognitive Disorder and their relatives: a qualitative study

OBJECTIVES

Alzheimer's disease (AD), the most common type of dementia, is one of the most feared diseases, obstructing help-seeking, and leading to discrimination. While research interest in fear of developing AD is increasing, little is known about its characterization, triggers, and consequences, especially among different cultures. In this study, we aimed at exploring and characterizing AD fear as experienced by laypersons (LP), persons with Mild Neurocognitive Disorder (MND), and their relatives, in Israel and Germany.

DESIGN

A qualitative study using focus groups (FGs) and semi-structured interviews was used. Thematic content analysis was conducted to extract key themes.

SETTING

Israeli and German not yet diagnosed people.

PARTICIPANTS

The study included a total of 130 participants (63 Israeli and 67 German participants) representing 3 groups: LP (n = 82), persons with MND (n = 28), and relatives of persons with MND (n = 20).

RESULTS

Two overarching themes were identified across groups and countries: fear of developing AD and fear of stigmatization. Other types of fear, such as fear of a person with AD, fear about the impact of a diagnosis of AD on family members, fear of becoming a caregiver, and fear of losing one's self-determination because of developing AD, were specific to a group type or country. Different types of fear were awakened by different triggers, and were dealt with different coping strategies.

Assessment-related anxiety among older adults: development of a measure

Older adults are the largest population seeking neuropsychological assessment services. Anxiety has been shown to impact test scores, yet no anxiety measure currently exists specific to older adult neuropsychological assessment. This study piloted and validated the Feelings About Neuropsychological Testing measure (FANT), a measure of neuropsychological assessment anxiety developed to measure the cognitive, affective, and physiological aspects of test and state anxiety. The measure was validated on 105 community based older adults aged 55 and older. All participants were administered the FANT, the Generalized Anxiety Disorder- seven item (GAD-7), Test Anxiety Inventory- Short Form (TAI-SF), Patient Health Questionnaire- nine item (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), Dementia Worry Scale (DWS), and PROMIS Cognitive Function Short Form- 6a (CFSF). The measure proved feasible to administer, both the State and Test-specific dimensions demonstrated good internal consistency (state: α =.832; test: α =.894), discriminant validity, and external validity (compared to GAD-7, TAI-SF, PHQ-9, DWS, and CFSF). FANT scores may reveal patients for whom anxiety disrupts attention and attentional control, and therefore has promise as a measure that may inform assessment findings and guide possible intervention to maximize performance during testing sessions and to inform data interpretation.

A Randomized Controlled Trial Investigating the Feasibility of a Low-Intensity Psychological Intervention for Fear of Memory Loss and Quality of Life in Older Adults: Protocol for the Reducing Fear and Avoidance of Memory Loss (REFRAME) Study

Background

Dementia is the most feared disease associated with aging. Prolonged fears about memory loss and dementia can have harmful consequences even in the absence of cognitive decline. Fear of dementia is associated with poorer health outcomes and psychological well-being and increased memory failures in older adults.

Objective

We will conduct a randomized controlled trial to determine the feasibility of a tailored, web-based mindfulness program to reduce fear of memory loss and increase quality of life in older adults experiencing heightened fear.

Methods

Eighty participants will be recruited and divided into 2 groups (40 in each group). One group will receive psychoeducation plus mindfulness training. A second group will receive psychoeducation, mindfulness training, and additional modules targeting maladaptive behavioral avoidance (ie, social and cognitive withdrawal).

Results

Our recent etiological model posits that maladaptive behavioral avoidance strategies critically underlie psychosocial dysfunction associated with fear of memory loss. Thus, we predict better outcomes in the second group, including reduced fear of memory loss (primary outcome), Alzheimer disease, anxiety, and subjective memory failures, and increased quality of life (secondary outcomes). Outcome measures will be applied at 5 time points (before, baseline, interim, and after the intervention, and at 3-month follow-up). Data will be analyzed using mixed models and correlations.

Conclusions

Results from this study will contribute to the current literature on dementia-related fear and improve our understanding of how to effectively address and reduce these fears.

A 2-Study Psychometric Evaluation of the Modified Dementia Worry Scale

A modified version of the Dementia Worry Scale (DWS) used the terminology “Alzheimer’s disease and related dementias” (versus the DWS’ use of “dementia”). Two studies investigated psychometric properties of the modified DWS (MDWS). Study 1 compared the psychometric properties of the DWS and MDWS; both versions had single factor structures and exhibited excellent internal consistency (αs ≥ .95). The MDWS exhibited greater test-retest reliability after a 4-week interval (DWS r = .68; MDWS r = .90). In Study 2, the MDWS again displayed a single factor structure, excellent internal consistency (α = .95), and good test-retest reliability after an 8-week interval (r = .78). Additionally, results support convergent validity between the MDWS and fear of dementia, subjective memory, general anxiety, health anxiety, and neuroticism. The MDWS is psychometrically consistent with the DWS, maintains strong test-retest reliability, and is appropriate for use in cross-sectional and longitudinal research.

Alzheimer Disease Worries, Fears, and Stigma and Their Relationship to Genetic and Interventional Research Engagement

BACKGROUND

Alzheimer disease (AD) research increasingly requires healthy individuals willing to undergo genetic testing.

OBJECTIVE

This study seeks to: (1) describe older adults' beliefs about AD genetic testing, worry about AD, and fear of AD stigma, and (2) explore how these constructs relate to research participation.

METHODS

Surveys were sent to participants active in AD-observational research and those that were not. Three measures of research participation were explored: (1) being a current research participant, (2) self-report of clinical trial participation, and (3) expressing genetic registry interest.

RESULTS

The majority of the 502 respondents perceived greater benefit than the risk associated with AD genetic testing. AD worry and perceptions of AD stigma were low. Higher levels of AD worry and lower perceptions of AD stigma were associated with being a current AD research volunteer. AD worry and stigma were unrelated to clinical trial participation or genetic registry interest; these research participation measures were associated with AD genetic testing benefit.

CONCLUSIONS

Beliefs about AD genetic testing, AD worry, and AD stigma are related to research participation, but relationships vary based on the research participation investigated. Future work should identify how these findings can inform outreach and recruitment efforts.

Conceptualization, measurement and correlates of dementia worry: A scoping review

PURPOSE

The combination of a growing population of older adults and increasing prevalence and awareness of dementia diagnoses suggests that dementia worry may also intensify. As a relatively new area of investigation, the dementia worry literature is growing, but variability in definitions and measurement continue. A scoping review was conducted to gather and examine existing research, as well as assist in guiding future studies in this area. The review focused on characterizing the conceptualization, measurement, and correlates of dementia worry.

METHODS

Using PubMed, CINAHL, AgeLine, and PsycINFO, a search of literature concerning dementia worry was completed.

RESULTS

A total of 45 articles examining dementia worry fulfilled the inclusion criteria. Most studies were cross-sectional (n = 39), quantitative (n = 38), and conducted in the United States (n = 22). Inconsistencies in the conceptualization, measurement, and correlates examined make it difficult to determine the meaning and true levels of dementia worry.

CONCLUSIONS

Recent attention to dementia worry has increased awareness of the basic concept and its correlates. However, the lack of unity in the definition and measurement of dementia worry impedes advancement in this research area, as well as in establishing its clinical significance.

The fear of Alzheimer's disease: mediating effects of anxiety on subjective memory complaints

Objectives: To determine if the fear of developing Alzheimer's disease (FDAD) construct, in combination with similar psychoemotional factors, could help elucidate the nature of older adults' subjective memory complaints (SMCs) and subsequent objective memory performance.Methods: One hundred ninety-three healthy older adults (aged 65-93) were administered clinician and self-report measures of depression, worry, anxiety, illness attitudes, and memory, and each rated their concern with developing AD.Results: Self-reported FDAD was not associated with objective memory performance (p > .05). FDAD, trait anxiety, general anxiety, and general and illness-related worry were independently associated with subjective memory report (ps < .05). The relationship between FDAD and subjective memory report was mediated by measures of general trait and state anxiety, but not general worry or illness-specific worry.Conclusions: FDAD was not associated with objective memory functioning, suggesting AD concerns were not reflective of memory pathology. The mediating effect of anxiety on the relationship between FDAD and subjective memory report suggests that assessment of anxiety, beyond AD fear, may help identify older adults at risk for developing negative perceptions of memory and related distress.

Combined Influences of Dementia Exposure and Personality on Self-Reported Memory Problems

The current study investigated whether having a first-degree relative with dementia influenced older adults' self-reported memory, if personality traits moderated these associations, and whether these associations differed by the type of item asked (ie, frequency of memory problems vs perceived memory decline). Data drawn from the Einstein Aging study included 454 older adults (Mage = 76.64, standard deviation = 4.77, 66.96% white, and 63% female). Multilevel modeling analyses showed participants who had a first-degree relative with dementia reported more frequent memory problems and were more likely to report memory decline over the past year. Among participants with a first-degree relative with dementia, higher levels of neuroticism were related to reports of more frequent memory problems at baseline, whereas higher levels of conscientiousness and lower levels of extraversion were related to reports of more frequent memory problems over time. Future research should consider personality traits and family history of dementia as potential contributors to self-reported memory problems.

Examining the Relationship Between Religious and Spiritual Motivation and Worry About Alzheimer's Disease in Later Life

As awareness of Alzheimer's disease and related disorders and diagnosis rates rise, concern about developing such conditions may also increase, referred to here as dementia worry (DW). Few studies have examined DW and potential protective factors. Religiosity provides diverse psychological benefits and may be associated with lower DW; however, intrinsic/extrinsic motivations were expected to differentially relate to DW. Among 83 older adults (M = 69.48 years), both greater intrinsic and extrinsic-social religious motivation were associated with lower DW. Results suggest internalizing one's religious beliefs and building a social network within a religious community may provide a psychological buffer against DW.

An Examination of Age-Based Stereotype Threat About Cognitive Decline

"Stereotype threat" is often thought of as a singular construct, with moderators and mechanisms that are stable across groups and domains. However, this is not always true. To illustrate this, the current review focuses on the stereotype threat that older adults face about their cognitive abilities. Drawing upon the multithreat framework, I first provide evidence that this is a self-concept threat and not a group-reputation threat. Because this differs from the forms of stereotype threat experienced by other groups (e.g., the threat that minority students face about their intellectual abilities), the moderators of stereotype threat observed in other groups (i.e., group identification) do not always generalize to age-based stereotype threat about cognitive decline. Looking beyond the forms of stereotype threat elicited, this review also provides evidence that the mechanisms underlying stereotype-threat effects may vary across the adult life span. Because of age-related improvements in emotion-regulation abilities, stereotype threat does not seem to reduce older adults' executive-control resources. Overall, this review highlights the need to approach the concept of stereotype threat with more granularity, allowing researchers to design more effective stereotype-threat interventions. It will also shed light on why certain stereotype threat effects "fail to replicate" across domains or groups.

Concern about developing Alzheimer's disease or dementia and intention to be screened: An analysis of national survey data

OBJECTIVE

Early diagnosis of Alzheimer's disease (AD) or dementia is important so that patients can express treatment preferences, subsequently allowing caregivers to make decisions consistent with their wishes. This study explored the relationship between people's concern about developing AD/dementia, likelihood to be screened/tested, if experiencing changes in cognitive status or functioning, and concerns about sharing the diagnostic information with others.

METHOD

A descriptive study was conducted using Porter Novelli's SummerStyles 2013 online survey data. Of the 6105 panelists aged 18+ who received the survey, 4033 adults responded (response rate: 66%). Chi squares were used with case-level weighting applied.

RESULTS

Almost 13% of respondents reported being very worried or worried about getting AD/dementia, with women more worried than men (p<.001), and AD/dementia caregivers more worried than other types of caregivers (p=.04). Women were also more likely than men to agree to be screened/tested if experiencing changes in memory and/or thinking (p<.001). The greater the worry, the more likely respondents would agree to be screened/tested (p<.001). Nearly 66% of respondents were concerned that sharing a diagnosis would change the way others think/feel about them, with women reporting greater concern than men (p=.003).

CONCLUSION

Findings demonstrate that level of worry about AD/dementia is associated with the reported likelihood that individuals agree to be screened/tested. This information will be useful in developing communication strategies to address public concern about AD/dementia that may increase the likelihood of screening and early detection.

Do Worries About Cognitive Functioning and Concerns About Developing Alzheimer’s Disease Affect Psychological Well-Being?

Objective: The objective of this study is to determine if cognitive worries affect psychological well-being, if these effects are long-term, and if such concerns affect well-being more so among persons with a parent having Alzheimer’s disease (AD). Method: We used structural equation models with three waves of data collected from persons ages 40 to 60 at T1. We created summative scores on five indicators of concerns about cognitive functioning and worries about dementia. Well-being measures included depression, life satisfaction, stress, and mastery. Results: We found (a) cognitive worries at Waves 1, 2, and 3 were generally associated with lower levels of psychological well-being at each of these waves; (b) there was no evidence of long-term, lagged effects, and (c) these relationships were statistically similar across groups of adult children and controls. Discussion: Because concerns about cognitive functioning and developing AD are pervasive among middle-aged and older persons, practitioners should be aware of their potentially deleterious effect on psychological well-being.

The impact of aging stereotypes on dementia worry

Dementia worry, an anxiety-related response to the possibility of developing dementia, represents an important yet underexplored health concern for an aging population. Such a construct is likely impacted by stereotypes concerning aging, including biased associations of aging with inevitable cognitive decline. The present article explores the impact of mixed positive and negative aging stereotype messages on levels of dementia worry. The Fear of Alzheimer's Disease Scale (FADS) was used to measure impact of priming with different proportions of positive and negative aging stereotype words. The priming intervention was modeled after Levy (J Pers Soc Psychol 71:1092-1107, 1996, doi:10.1037/0022-3514.71.6.1092). Eighty older adult participants (M_age = 71.65, SD = 6.57) were exposed to mostly positive aging stereotype words, half positive/half negative words, mostly negative words, all negative words, or non-stereotype words. Mean FADS item response was significantly impacted by priming such that those in the all negative condition had highest levels of dementia worry, F(4, 75) = 2.48, p = .05, [Formula: see text]. This effect was strengthened when relevance of aging stereotypes was controlled for, p < .01. Results suggested that brief exposure to negative aging stereotype content increased levels of dementia worry, particularly when stereotypes were self-relevant. These findings indicate addressing aging stereotypes may be one way of impacting dementia worry.
