<b><i>Background:</i></b> Measures of memory awareness based on evaluative judgement and performance monitoring are often regarded as equivalent, but the Levels of Awareness Framework suggests they reflect different awareness phenomena. Examination of memory awareness among groups with differing degrees of impairment provides a test of this proposition. <b><i>Method:</i></b> Ninety-nine people with dementia (PwD), 30 people with mild cognitive impairment (PwMCI), and their relatives completed isomorphic performance monitoring and evaluative judgement measures of memory awareness and were followed up at 12 and (PwD only) 20 months. In addition to the resulting awareness indices, comparative accuracy scores were calculated using the relatives' data to establish whether any inaccuracy was specific to self-ratings. <b><i>Results:</i></b> When making evaluative judgements about their memory in general, both PwD and PwMCI tended to overestimate their own functioning relative to informant ratings made by relatives. When monitoring performance on memory tests, PwD again overestimated performance relative to test scores, but PwMCI were much more accurate. Comparative accuracy scores indicated that, unlike PwD, PwMCI do not show a specific inaccuracy in self-related appraisals. <b><i>Conclusions:</i></b> The results support the proposition that awareness indices at the levels of evaluative judgement and performance monitoring should be regarded as reflecting distinct awareness phenomena.
ABSTRACT Background/Aims: To compare memory evaluations in healthy older people and people with Alzheimer's disease (AD) and present standardised individual and dyadic methods for classifying degree of memory awareness in the participants with dementia. Methods: Cross-sectional study evaluating awareness of memory functioning and performance and providing normative data for healthy individuals and couples, together with comparison data from people with AD. Results: As a group, older people are reasonably accurate raters of their own memory functioning and performance, although considerable individual differences can be observed, and control dyads show good comparative accuracy. Comparing normative data from the control group to data from participants with AD confirms that significant overestimation is a frequent feature among people with dementia, with approximately two-thirds showing this pattern, although significant under-estimation is also reliably observed in a small proportion of people with dementia. Different types of measure elicit different profiles of memory awareness in participants with dementia. Conclusion: Normative data from older individuals and couples provides useful percentile-based indices for determining level of memory awareness in people with dementia.
ABSTRACT Objectives: Being a family caregiver, and in particular giving care to someone with dementia, impacts mental and physical health and potentially reduces the ability of caregivers to “live well.” This paper examines whether three key psychological resources—self-efficacy, optimism, and self-esteem—are associated with better outcomes for caregivers of people with dementia. Design and Participants: Caregivers of 1,283 people with mild-to-moderate dementia in the Improving the Experience of Dementia and Enhancing Active Life (IDEAL) project responded to measures of self-efficacy, optimism, and self-esteem, and “living well” (quality of life, life satisfaction, and well-being). Multivariate linear regression was used to examine the association between psychological resources and “living well”. Results: Self-efficacy, optimism, and self-esteem were all independently associated with better capability to “live well” for caregivers. This association persisted when accounting for a number of potential confounding variables (age group, sex, and hours of caregiving per day). Conclusions: Low self-efficacy, optimism, and self-esteem might present a risk of poor outcomes for caregivers of people with dementia. These findings encourage us to consider how new or established interventions might increase the psychological resilience of caregivers.
Spouse caregivers of people with dementia (PwD) report relatively poor marital relationship quality (RQ), but few studies have obtained the perspective of the PwD, examined discrepancies between spouses, or considered changes in RQ over time. This study explored caregiver and PwD perceptions of RQ, identified associated factors, and examined changes over an 18-month period. Participants were 54 couples where one spouse had early-stage dementia and 54 were control couples. RQ was assessed with the Positive Affect Index. Measures of mood, stress, and quality of life (QoL) were also administered. The clinical couples were followed up after 9 and 18 months. Caregivers gave significantly lower RQ ratings than controls. PwD ratings did not differ significantly from those of caregivers or controls. Dyadic discrepancies were significantly greater in the clinical than in the control group. Caregiver ratings were associated with stress, whereas PwD ratings were associated with depression and QoL. Discrepancies were associated with caregiver stress and with PwD mood, QoL, and age. Caregiver ratings declined significantly over time; PwD ratings did not decline significantly, but showed different trends for men and women. It is important to consider RQ when considering how to support couples where one partner has early-stage dementia.
There is a major need for longitudinal research examining the experiences of people with dementia and their primary carers, as relatively little is known about how the factors associated with capability to 'live well' vary over time. The main aim of the IDEAL-2 study is to investigate how and why, over time, people with dementia and their primary carers might vary in their capability to live well with dementia, whilst exploring both their use of health and care services and their unmet needs. IDEAL-2 will build on the Improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort of 1547 people (who, at recruitment between July 2014 and July 2016, had mild-to-moderate dementia), and their 1283 primary carers in Great Britain. The existing cohort will be enriched with additional participants with mild-to-moderate dementia (and their primary carers where available and willing) from the following groups: people with rarer forms of dementia, and/or those who are ≥90 years or < 65 years of age at time of recruitment. We will assess the primary outcome, capability to live well with dementia, and the factors influencing it using questionnaires at yearly intervals for 3 years. Additionally, we will seek to link the cohort data with administrative data to obtain information about health service use. Some participants will be invited for in-depth face-to-face interviews. The cohort study will be supplemented by linked research focusing on: the co-production of new measures of living well; including the perspectives of people with advanced dementia living in residential care settings; including people with dementia from black, Asian, and minority ethnic groups; and understanding the experience of people living with undiagnosed dementia. IDEAL-2 will provide evidence about the key indicators of, and factors associated with, living well over the course of dementia and how these differ for particular subgroups. It will tell us which combinations of services and support are most beneficial and cost-effective. Moreover, the IDEAL-2 study will gather evidence from under-researched groups of people with dementia, who are likely to have their own distinct perceptions of living well.
Key components of cognitive lifestyle are educational attainment, occupational complexity and engagement in cognitively stimulating leisure activities. Each of these factors is associated with experiencing fewer depressive symptoms in later life, but no study to date has examined the relationship between overall cognitive lifestyle and depressive symptoms. This task is made more complex because relatively few older participants in cross-sectional studies will be currently experiencing depression. However, many more will show evidence of a depressive thinking style that predisposes them towards depression. This study aimed to investigate the extent to which cognitive lifestyle and its individual components are associated with depressive thoughts and symptoms. Two hundred and six community-dwelling participants aged 65+ completed the depressive cognitions scale, the geriatric depression scale and the lifetime of experiences questionnaire, which assesses cognitive lifestyle. Correlational analysis indicated that each of the individual lifestyle factors—education, occupational complexity and activities in young adulthood, mid-life and later life—and the combined cognitive lifestyle score was positively associated with each other and negatively with depressive symptoms, while all except education were negatively associated with depressive thoughts. Depressive thoughts and symptoms were strongly correlated. Cognitive lifestyle score explained 4.6 % of the variance in depressive thoughts and 10.2 % of the variance in depressive symptoms. The association of greater participation in cognitive activities, especially in later life, with fewer depressive symptoms and thoughts suggests that preventive interventions aimed at increasing participation in cognitively stimulating leisure activity could be beneficial in decreasing the risk of experiencing depressive thoughts and symptoms in later life.
With the growing older population worldwide there is increasing emphasis on helping this population age well. Cognitive reserve may provide a pathway to maintaining both cognitive and emotional health in later life. Previous research has shown that higher levels of cognitive reserve are associated with better cognitive function, reduced risk of dementia and lower levels of depressive symptoms. This study of 236 community-dwelling people aged 60+ sought to assess whether cognitive reserve is also associated with greater self-perceived quality of life, self-esteem and self-efficacy. Cognitive reserve was assessed with the Lifetime of Experiences Questionnaire, which assesses a combination of education, occupational complexity, and lifetime engagement in cognitive and social activity. Higher levels of cognitive reserve were associated with significantly higher levels of self-reported quality of life, self-esteem, and self-efficacy. Comparing the individual constituent elements of the cognitive reserve measure, education was the factor most strongly associated with self-efficacy, while engagement in cognitive and social activity in later life was the factor most strongly associated with quality of life and self-esteem. Occupational complexity was not associated with any of the dependent variables, suggesting the results were not attributable solely to socioeconomic status. Encouraging people to continue to engage in the cognitive and social activities associated with higher cognitive reserve may increase well-being in later life in terms of quality of life, self-esteem and self-efficacy as well as helping to maintain cognitive function.
