Successful ageing in the oldest old: objectively and subjectively measured evidence from a population-based survey in Germany

Despite rapid increase of people aged 80 and over, concepts of successful ageing (SA) are primarily examined for people below that age. Therefore, successful ageing was examined in a population-based representative sample of N = 1863 people aged 80 to 102 (NRW80+) with 11% living in institutionalized settings. In this survey on quality of life and well-being, multiple linear and logistic regression models were used to calculate the distribution of successful agers. According to Rowe and Kahn’s objective definition, 9% of the sample aged successfully, but one-third (33%) still met four to five SA criteria. This is in line with the theoretical a priori criterion of 10% in a normal distribution of a sample, while 80% age normally and 10% pathologically. However, averages of life satisfaction, affective well-being, positive ageing experience and valuation of life were high. The majority of the oldest old (65%) are successful agers in their own subjective perception, which is not in line with objective measurements. Moreover, 11% of objectively measured successful agers do not meet subjective criteria. These empirical findings reveal a remarkable discrepancy between objective and subjective criteria of SA. Future research on concepts that define successful ageing for the oldest old should consider more holistic markers of success, e.g., outcomes of productive social engagement.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10433-021-00609-7.     

The assessment of views on ageing: a review of self-report measures and innovative extensions

This is a review of existing self-report measures for assessing views on ageing. It provides an overview of instruments, for which basic psychometric properties are available and describes them according to the purposes for which they are suitable. Literature search resulted in the inclusion of 89 instruments which were categorised along eight dimensions. The majority of measures focus on explicit cognitions about people’s own age and ageing or other (older) people. A substantial amount of tools account for the multidimensionality and multidirectionality of views on ageing, i.e. the idea that ageing is accompanied by both gains and losses in several different domains. To some extent, measures reflect that ageing is a long-term process and that views on ageing are malleable, rather than just stable traits. Cluster analysis revealed heterogeneity in instruments regarding the dimensions of Ecosystem, Balance, Stability, Dynamics, and Complexity. It becomes apparent, however, that approaches to measure views on ageing should be extended to more specifically target the implicit level as well as affective, physiological, and behavioural manifestations. Additionally, means for capturing views on ageing on the societal level and tools with a distinct time reference are needed. This is particularly important when one wants to account for the lifelong dynamics of views on ageing.     

Volunteering as a productive ageing activity: the association with fall-related hip fracture in later life

This paper aims to contribute to the literature on the relationship between productive and healthy ageing as two key theoretical concepts in contemporary ageing. Specifically, volunteering as a productive activity in later life has been associated with social and health benefits for older people. Evidence from the literature has generally focused on global outcomes, such as mortality and self-rated health, or on measures of psychological well-being. This study explored whether volunteering is protective of an important adverse health outcome in later life, that of fall-related hip fracture, utilising data from a case control study of 387 participants. The results showed that volunteer activity in older age remained significantly protective of hip fracture risk [OR: 0.61 (0.38–0.99)], independent of social and physical activity, social support and health status, supporting the hypothesis of a relationship between the concepts of productive and healthy ageing. Whilst further studies are clearly needed to establish causality, these results suggest that health benefits of volunteering in later life might be more extensive than previous studies have shown.     

Ageism and older people’s health and well-being during the Covid-19-pandemic: the moderating role of subjective aging

In the Covid-19 pandemic, being older means being in a special focus: Probabilities for severe infections and mortality rise with increasing age and protective measures for this population group have been increased. This was accompanied by public discourse that portrayed older adults stereotypically as vulnerable and frail but also highlighted the hardships younger people have to endure to protect them. Given the possibly detrimental effects of ageism on individuals and societies, we were interested in older adults’ perception of ageism in the Corona-crisis and its relation to their health and well-being. Furthermore, we were interested in subjective aging variables as moderators in the ageism–health relationship. In June 2020, N = 611 independently living people aged 60 + from the Grand Duchy of Luxembourg were recruited via a survey research institute and interviewed online or by phone. They reported on perceived ageism in different contexts, their life satisfaction, subjective health, subjective age and self-perceptions of aging. Depending on context, ageism was perceived by around 20% of participants, and overall negatively related to subjective health and life satisfaction after the onset of the pandemic. Moderated hierarchical regressions showed that a younger subjective age buffered the negative effect of ageism on subjective health, while perceiving aging as social loss increased its effect on life satisfaction. We discuss the importance of addressing and reducing ageism (not only) in times of crisis and the consequences for individuals and societies.     

Physical activity and subjective age across adulthood in four samples

The present study examined the prospective association between physical activity and subjective age across adulthood and factors that mediate this association. Participants were adults aged from 20 to 90 years (N > 10,000) drawn from the Wisconsin Longitudinal Study graduates and siblings samples, the Health and Retirement Study and the Midlife in the United States Survey. In the four samples, physical activity was assessed at baseline and subjective age was measured 8 to 20 years later. Personality, self-rated health, disease burden, depressive symptoms, and cognition were assessed as potential mediators. In the four samples, higher physical activity at baseline was associated with a younger subjective age at follow-up. Logistic regression revealed that physical activity was related to a 30–50% higher likelihood of feeling younger 8 to 20 years later. Significant indirect effects were found through openness to experience and self-rated health in the four samples. This study provides new evidence on the link between a health-related behavior and subjective age. Physically active individuals may sustain health and an open psychological disposition that is associated with feeling younger.     

Serious health events and their impact on changes in subjective health and life satisfaction: the role of age and a positive view on ageing

Various studies have pointed to the great importance of subjective health as an indicator for mortality in older age, while less is known about factors that contribute to changes of subjective (self-rated) health over time. Based on a nationwide longitudinal survey (German Ageing Survey, N = 1,286; initial age 40–85), two major findings emerged: first, the incidence of a serious health event caused greater changes in subjective health and life satisfaction in middle compared to older age. This was as expected because serious health events are less common in middle age and are correspondingly experienced more often as an “off-time event”. Secondly, the study extended previous findings on the impact of a positive view of ageing on health by showing that this optimistic view positively affects subjective health and life satisfaction even in the face of a serious health event. Overall, the study indicates that a positive view on ageing is an important psychological resource in the case of a serious health event, both when it occurs on-time or off-time from a developmental perspective.

Lay perceptions of successful ageing: findings from a national survey of middle aged and older adults in Britain

The main aim of the research presented here was to identify perceptions of successful ageing among people in middle and older age groups. The method was a British population survey of 854 community-dwelling men and women aged 50 or more. Just over three-quarters of respondents rated themselves as ageing successfully (“very well” or “well”). Respondents’ definitions of successful ageing, and the reasons given for their self-ratings, based on open-ended questioning, illustrated the multidimensionality of the concept. Definitions varied with respondents’ characteristics. Self-rated health status and quality of life consistently retained significance in the multivariate models of predictors of self-rated successful ageing, while self-rated quality of life made the greatest contribution to the models. Reporting a longstanding, limiting illness was not significant. The overall models explained about a third of the variation in self-rated successful aging. Lay definitions of successful ageing were multidimensional. A biomedical perspective of successful ageing therefore needs balancing with a psycho-social perspective, and vice versa. This is particularly relevant for biomedical approaches which have largely ignored the rich tradition of social and psychological research on this topic. Self-rated successful ageing should be included in measuring instruments to enhance social relevance. This research, with the use of open-ended questioning, makes a novel methodological contribution to the literature, is unique in questioning middle aged as well as older people, and provides a British perspective on a largely US and German topic.An erratum to this article can be found at     

Daily fluctuations in subjective age and depressive symptoms: the roles of attitudes to ageing and chronological age

Studies indicate that both subjective age—individuals’ perception of their own age as older or younger than their chronological age, and attitudes to ageing are related to physical and mental health. Less is known about the possible dual effect of these two constructs of subjective views of ageing. In the current study, 334 participants (aged 30–90, M?=?58.15) reported their daily subjective age and mental health along 14 consecutive days. Attitudes to ageing were measured at baseline. Results indicated that daily variation in subjective age was related to daily variation in depressive symptoms, such that people experienced more depressive symptoms at days they felt older. Furthermore, we found that attitudes to ageing (perceptions of losses, physical change, and psychological growth) moderated this relationship. The covariation between daily subjective age and daily depressive symptoms was stronger when attitudes to ageing were less favorable (e.g., high perceptions of losses and low psychological growth). The moderating effect of losses was especially prominent among older participants. This indicates that attitudes to ageing moderate the toll that feeling old takes on mental health, especially in older age. The results also emphasize the need to understand how different subjective views on ageing, measured in different time frames, operate interactively to shape individual’s daily experiences.

     

Morphometric skin characteristics dependent on chronological and biological age: the Leiden Longevity Study

The effect of chronological age on skin characteristics is readily visible, and its underlying histological changes have been a field of study for several years. However, the effect of biological age (i.e. a person’s rate of ageing compared to their chronological age) on the skin has so far only been studied in facial photographs. Skin biopsies obtained from middle-aged offspring of nonagenarian siblings that are genetically enriched for longevity were compared to their partners who represent the general Dutch population. Though of the same chronological age, the offspring were previously observed to be of a younger biological age than their partners. The biopsies were analysed on several aspects epidermal and elastic fibre morphology. We investigated whether these skin characteristics were dependent on chronological age, familial longevity (the difference between the offspring and partners) and Framingham heart risk scores, adjusted for external stressors. A decreased thickness and flattening of the epidermis as well as an increased amount of elastic fibres in the reticular dermis were observed with chronological age (P < 0.001, P < 0.001 and P = 0.03, respectively), but no effect of familial longevity was found. The Framingham heart risk score was associated with some skin characteristics. A slower rate of skin ageing does not mark offspring from nonagenarian siblings. Epidermal and elastic fibre morphometric characteristics are not a potential marker for familial longevity in middle-aged subjects enriched for familial longevity.

Views on ageing: a lifespan perspective

Views on ageing (VoA) have special relevance for the ageing process by influencing health, well-being, and longevity. Although VoA form early in life, so far, most research has concentrated on how VoA affect later middle-aged and older adults. In this theoretical article, we argue that a lifespan approach is needed in order to more fully understand the origins of VoA, how they change over ontogenetic time, and how they shape development across the full breadth of the lifespan. We begin by explicitly linking VoA to fundamental principles of lifespan development. We review existing theories of VoA and discuss their respective contributions and limitations. We then outline a lifespan approach to VoA that integrates existing theories and addresses some of their limitations. We elaborate on three core propositions of a lifespan approach to VoA: (1) VoA develop as the result of a dynamic, ongoing, and complex interaction between biological-evolutionary, psychological, and social-contextual factors; however, the relative importance of different sources changes across the lifespan; (2) VoA impact development across the whole lifespan; however, different outcomes, mechanisms, and time frames need to be considered in order to describe and understand their effects; and (3) VoA are multidimensional, multidirectional, and multifunctional throughout life, but their complexity, meaning, and adaptivity change across the lifespan. We conclude with recommendations for future lifespan research on VoA.     

Shifting self-perceptions of ageing: differential effects of value priorities on self-perceptions of ageing beyond age stereotypes

Self-perceptions of ageing (SPA) are important predictors of health in later life. However, research on antecedents of SPA other than age stereotypes is scarce. To address this gap, this study investigates the impact of personal value priorities beyond age stereotypes on SPA. Can values as the motivational basis of attitudes and evaluations predict gain- and loss-related SPA? To answer this question, we conducted multiple regression analyses of longitudinal data from two waves (2008, 2011) of the German Ageing Survey (DEAS; N = 6089, age range in 2008: 40–93 years). Gain- and loss-related SPA as well as age stereotypes were assessed with two AgeCog scales and personal values with the 21-item Portrait Values Questionnaire. Results indicate that value priorities relate to SPA longitudinally in domain-specific ways: People with a value priority of openness to change and self-transcendence reported more gain-related SPA at follow-up, whereas those who prioritized conservation reported less gain-related SPA. In the domain of loss-related SPA, those people with a value priority of self-enhancement reported more and those prioritizing self-transcendence reported less loss-related SPA at follow-up. These results complement and extend recent findings on the role of personality for SPA. They suggest that whether people focus on the gains or losses that occur with age, whether they perceive ageing as a threat or chance, is not only shaped by their age stereotypes, but also by what they find important—their values.     

The Effects of Functional Health Status on the Everyday Life of Older People in Japan

The effects of functional health status on socio-psychological aspects of everyday life were analysed with data from 2,255 Japanese persons aged 55 years and over. The sample was randomly selected from the residents' registration (response rate was 75.2%). The socio-psychological variables were self-rated health, working status, frequency of going out, leisure activities, social networks, social supports, and subjective well-being. Health status had significant and positive effects on these variables when the effects of age, gender and educational attainment were controlled. The results seem to confirm the notion that health status is the pivotal condition of quality of life in old age and ageing.     

Health and subjective well-being: a replicated secondary data analysis

The purposes of this article are to use replicated secondary data analysis to summarize information about the relationship between health and subjective well-being and to assess the strengths and weaknesses of replicated secondary data analysis as a mode of research synthesis. The findings from thirty-seven replications in seven surveys suggest a moderate and robust relationship between self-rated health and subjective well-being. Physician-assessed health, in contrast, exhibits weaker and less robust associations with subjective well-being. Further, the relationship between health and subjective well-being is conditioned by age and is stronger for measures of negative than positive affect. The principal advantages of replicated secondary data analysis, vis-a-vis other modes of research synthesis, are cost-effectiveness, increased ability to apply multivariate statistical techniques, and greater control and flexibility for the investigator. We suggest, nonetheless, that different modes of research synthesis can best be used for different purposes.     

Reactions to ageing among Australian psychologists

Objective: To assess attitudes towards personal ageing among Australian psychologists. Methods: Six hundred and four practising psychologists were surveyed using the Reactions to Ageing Questionnaire (RAQ). Potential predictors of attitudes to ageing, such as age, gender and number of years in clinical practice were examined, together with the amount and quality of contact with older family members and older friends. Measures related to the training of psychologists were also of interest. Results: The strongest significant predictors of attitudes to ageing were respondents’ age and positive attitudes towards conducting therapy with older clients. Contact and training variables were not associated with scores on the RAQ. Conclusion: These results highlight age as a contributing factor in attitude formation.     

Socioeconomic status and age identity: the role of dimensions of health in the subjective construction of age

OBJECTIVES: This study examines health inequality as a potential explanation for socioeconomic differences in age identity. The following dimensions of health are examined: comparative self-rated health, self-assessed changes in physiological well-being, prospective self-rated health, perceived control over health, chronic conditions, and parents' health. Components of health also are explored as possible mediators of age differences in the effect of socioeconomic status on age identity. METHODS: Using the National Survey of Midlife Development in the United States, ordinary least squares regression models of age identity are estimated for a representative sample of the noninstitutionalized U.S. population between the ages of 25 and 74 (n = 2,864). RESULTS: The older identities held by the less socioeconomically advantaged are explained by their worse health, particularly their less favorable predictions of future health, compared with their wealthier peers. Differences in age identity by education and perceived financial well-being are greatest among older adults; however, health only partially accounts for these age patterns. DISCUSSION: This study reveals that health inequalities shape the subjective experience of aging. Further work using longitudinal data is needed to determine the precise causal pathways linking socioeconomic status, health, and age identity.     

Big Five and psychological and subjective well-being in Colombian older adults

The goal of the current study was to investigate the relationships between the Five Factor Model of personality and the dimensions of subjective well-being (positive affect, negative affect, and life satisfaction), and psychological well-being (self-acceptance, personal growth, environmental mastery, autonomy, positive relations with others, and purpose in life). Participants included 618 Colombian adults aged 60–92 years. Multiple linear regression analyses were conducted. Regarding the subjective well-being, neuroticism was associated with lower scores on life satisfaction, and positively associated with negative affect, whereas extroversion and conscientiousness were associated with higher scores on life satisfaction and positive affect. For psychological well-being, neuroticism showed a negative and significant association with all of the psychological well-being dimensions, except purpose in life, whereas extroversion and conscientiousness showed a significant and positive relationship with the six dimensions. Neuroticism, extraversion, and conscientiousness represent personality predispositions for general well-being. Extraversion and conscientiousness are predictors of optimal aging. Neuroticism was the only significant predictor of negative affect.     

Perceived personal deadlines for late-life preparation across adulthood

Throughout adulthood, individuals follow personal timetables of deadlines that shape the course of aging. We examine 6-year-longitudinal data of perceived personal deadlines for starting with late-life preparation across adulthood. Findings are based on a sample of 518 adults between 18 and 88 years of age. Multilevel regression analyses were conducted to explore changes in personal deadlines for preparation in five domains (i.e., finances, end of life, housing, social connectedness, caregiving) in relation to calendar age, self-rated health, subjective position in life, and sociodemographic variables. Findings suggest that personal deadlines for starting preparatory activities differ depending on calendar age and domain of late-life preparation. Older adults as compared to younger adults are likely to report narrower deadlines for beginning with late-life preparation. Perceived deadlines for late-life preparation were furthermore found to be preponed and slightly dilated over time. Findings suggest that depending on age-graded opportunity structures, individuals flexibly adjust their personal deadlines for late-life preparation.Electronic supplementary materialThe online version of this article (10.1007/s10433-020-00581-8) contains supplementary material, which is available to authorized users.     

Dimensionen und Deutungsmuster des Alterns

Attitudes about older people and being old develop in the early and middle phases of life and influence the subsequent aging process. Because aging processes vary across different domains of life and functioning, one cannot assume unanimously negative or positive attitudes towards old age and aging. Thus, in the psychological part of the project Zones of Transition (??Zonen des übergangs??), age stereotypes and views of the self in old age were assessed in different life domains and for different age groups, and their relation to well-being and the self-concept was investigated. The project also focused on the analysis of attitudes towards one??s personal way of living in old age. A questionnaire was developed that assesses those attitudes on the basis of the dimensions ??active commitment?? and ??pleasure and leisure??. Our results support a multidimensional conception of attitudes towards aging and way of living in old age as well as of their influence on development across the lifespan.
