Younger Than Ever? Subjective Age Is Becoming Younger and Remains More Stable in Middle-Age and Older Adults Today.

Little is known about historical shifts in subjective age (i.e., how old individuals feel). Moving beyond the very few time-lagged cross-sectional cohort comparisons, we examined historical shifts in within-person trajectories of subjective age from midlife to advanced old age. We used cohort-comparative longitudinal data from middle-age and older adults in the German Ageing Survey (N = 14,928; ~50% female) who lived in Germany and were between 40 and 85 years old when entering the study. They provided up to seven observations over 24 years. Results revealed that being born later in historical time is associated with feeling younger by 2% every birth-year decade and with less intraindividual change toward an older subjective age. Women reported feeling younger than men; this gender gap widened across cohorts. The association of higher education with younger subjective age became weaker across cohorts. Potential reasons for the subjective-rejuvenation effect across cohorts are discussed.

Self-reported hearing and awareness of age-related change : A domain-specific perspective.

BACKGROUND: Impaired hearing is associated with disadvantages in developmental outcomes, such as compromised everyday social communication or reduced well-being. Hearing impairment might also have an impact on how individuals evaluate their own aging as deterioration in hearing can be interpreted as being age-related and as a phenomenon individuals attribute to getting older. OBJECTIVE: This study investigated how self-reported hearing is related to awareness of age-related change (AARC). MATERIAL AND METHODS: AARC is a multidimensional construct comprising perceived age-related gains and losses in general as well as across five functional domains (health and physical functioning, cognitive functioning, interpersonal relations, social cognitive and social emotional functioning, lifestyle and engagement). A sample of 423 individuals (age range 40-98 years; mean age, M = 62.9 years; standard deviation (SD) = 11.8 years) was assessed up to 3 times over approximately 5 years. RESULTS: Based on longitudinal multilevel regression models, controlling for age, gender, subjective health and education, it was found that poorer self-reported hearing was associated with more perceived general AARC losses as well as with more AARC losses in health and physical functioning and in cognitive functioning at baseline. With an older age at baseline, poorer self-reported hearing was associated with a steeper decline in AARC gains regarding interpersonal relations over time, whereas in those who were younger at baseline poorer hearing was related to fewer gains in social cognitive and social emotional functioning at baseline. DISCUSSION: Self-reported hearing reveals differential associations with AARC domains; however, changes in most AARC domains of gains and losses seem to be only weakly related to subjective hearing.

The Impact of the COVID-19 Pandemic on Trajectories of Well-Being of Middle-Aged and older Adults: A Multidimensional and Multidirectional Perspective.

The COVID-19 pandemic has resulted in profound changes of individuals' everyday lives. Restrictions in social contacts and in leisure activities and the threatening situation of a spreading virus might have resulted in compromised well-being. At the same time, the pandemic could have promoted specific aspects of psychosocial well-being, e.g., due to intensified relationships with close persons during lockdown periods. We investigated this potentially multidimensional and multi-directional pattern of pandemic-specific change in well-being by analyzing changes over up to 8 years (2012-2020) in two broad well-being domains, hedonic well-being (life satisfaction) and eudaimonic well-being (one overarching eudaimonic well-being indicator as well as environmental mastery, personal growth, positive relations with others, and self-acceptance), among 423 adults who were aged 40-98 years in 2012. By modelling longitudinal multilevel regression models and allowing for a measurement-specific intra-individual deviation component from the general slope in 2020, i.e. after the pandemic outbreak, we analyzed potential normative history-graded changes due to the pandemic. All mean-level history-graded changes were nonsignificant, but most revealed substantial interindividual variability, indicating that individuals' pandemic-related well-being changes were remarkably heterogeneous. Only for personal growth and self-acceptance, adding a pandemic-related change component (and interindividual variability thereof) did not result in a better model fit. Individuals with poorer self-rated health at baseline in 2012 revealed a pandemic-related change toward lower life satisfaction. Our findings suggest that not all well-being domains - and not all individuals - are equally prone to "COVID-19 effects", and even pandemic-associated gains were observed for some individuals in certain well-being domains.

Nine-year changes in self-reported problems with vision and hearing among older adults: do subjective age views matter?

OBJECTIVES: So far, little is known about linkages between subjective age views and long-term changes in vision and hearing. METHOD: We examined the predictive role of two key measures of subjective age views (attitude toward own aging [ATOA]; aging-related cognitions comprising continuous growth, social loss, and physical decline) for changes in self-reported problems with vision and hearing over a period of up to 9 years. A subsample of the German Ageing Survey was used, consisting of 2,499 older adults. RESULTS: Controlling for socio-demographic characteristics, self-rated health, and depressive symptoms, we found that with increasing age, more favorable ATOA scores, as well as higher scores on continuous growth and lower scores on physical decline, were associated with fewer self-reported vision problems at baseline. With advancing age, more favorable ATOA scores were also related with fewer hearing problems at baseline. However, among individuals with an older baseline age, more favorable ATOA scores were associated with a steeper increase in vision problems. Higher scores on continuous growth were related with less increase in hearing problems, independent of age. CONCLUSION: Our findings suggest that subjective age views predict individuals' self-reported vision and hearing problems.

Pain Intensity, Disability, and Quality of Life in Patients with Chronic Low Back Pain: Does Age Matter?

OBJECTIVE: Nonspecific chronic low back pain (CLBP) is a frequent medical condition among middle-aged and older adults. Its detrimental consequences for functional ability and quality of life are well known. However, less is known about associations of chronological age with disability and well-being among CLBP patients. Coping with pain may be harder with advancing age due to additional age-associated losses of physical, sensory, and other resources, resulting in higher disability and lower quality of life. Alternatively, older patients may feel less impaired and report higher quality of life than younger patients because the experience of chronic pain may be better anticipated and more "normative" in old age. METHODS: We investigated an age-heterogeneous sample of 228 CLBP patients (mean age = 59.1 years, SD = 10.2 years, range 41-82 years). Our outcomes were pain intensity, pain disability (as assessed by self-reported activity restrictions and performance-based tests), and measures of quality of life (health-related quality of life: SF-12 physical and mental health; well-being: anxiety, depression, perceived control over life, affective distress). RESULTS: Although older patients had higher performance-based disability, they scored higher on mental health and on most measures of well-being than younger patients. CONCLUSIONS: Our findings provide evidence for a "paradoxical" pattern of age effects in CLBP patients and are thus in line with other studies based on nonclinical samples: Although disability in CLBP patients increases with advancing age, indicators of quality of life are equal or even higher in older patients.

Profiles of Subjective Well-being in Patients with Chronic Back Pain: Contrasting Subjective and Objective Correlates.

OBJECTIVE: The detrimental impact of nonspecific chronic low back pain (CLBP) on quality of life is well known. However, patients with CLBP represent a remarkably heterogeneous group, and not all of them report compromised well-being. METHODS: In this study, we investigated this heterogeneity by identifying profiles (or clusters) of well-being and their correlates in 239 CLBP patients. To take the multidimensionality of subjective well-being into account, we included multiple well-being indicators (depression, anxiety, affective distress, perceived control over life). For an in-depth characterization of the well-being profiles, we assessed 1) sociodemographic indicators (age, gender, education, marital status, occupational status), 2) pain-related measures (pain intensity, subjective and objective pain disability, number of pain locations), 3) psychosocial resources (mental health, resilience, perceived support), 4) biographical factors (trauma), and 5) somatosensory profiles based on quantitative sensory testing. RESULTS: Based on two-step cluster analysis, we identified three distinct well-being profiles, characterized by either generally high well-being (cluster 1, n = 51), moderate well-being (cluster 2, n = 104), or consistently low well-being (cluster 3, n = 77), respectively. Most differences between the derived well-being profiles regarding sociodemographic, psychosocial, and biographical measures were of weak to moderate effect size. Larger effect sizes were observed for differences in pain intensity and subjective, but not objective, pain disability. Finally, the largest effects were found for differences in psychosocial resources. CONCLUSIONS: Our findings suggest that not only in nonclinical samples, but also in patients with chronic pain, well-being is more closely associated with psychological resources and subjective evaluations than with objective parameters.

Assimilative and accommodative coping in older adults with and without sensory impairment: four-year change and prospective relations with affective well-being.

Objectives: Sensory impaired older adults may be particularly dependent on coping strategies such as assimilation (or tenacious goal pursuit [TGP]) and accommodation (or flexible goal adjustment [FGA]) to secure high levels of well-being. We investigated if late-life changes in these coping strategies and prospective associations of TGP and FGA with affective well-being vary according to sensory impairment status. Method: Our study sample consisted of 387 adults aged 72-95 years (M = 82.50 years, SD =4.71 years) who were either visually impaired (VI; n = 121), hearing impaired (HI; n = 116), or sensory unimpaired (UI; n = 150). One hundred sixty-eight individuals were reassessed after approximately 4 years. Results: Both VI and HI revealed a decrease in TGP, whereas TGP remained stable in UI. For FGA, a significant increase in HI was observed, whereas a significant decline emerged in UI. Controlling for age, gender, and cognitive abilities, higher TGP at baseline was significantly associated with higher negative affect 4 years later in VI. Moreover, the positive association between baseline FGA and subsequent positive affect was stronger in HI than in UI older adults. Conclusion: Our findings suggest that older adults with sensory impairments reveal trajectories of assimilative and accommodative coping and associations of TGP and FGA with affective well-being that are different from sensory unimpaired individuals.

Visual Acuity and Cognition in Older Adults With and Without Hearing Loss: Evidence For Late-Life Sensory Compensation?

OBJECTIVES: Relationships between cognitive and sensory functioning become stronger with advancing age, and the debate on underlying mechanisms continues. Interestingly, the potential mechanism of compensation by the unaffected sensory modality has so far been investigated in younger age groups with congenital sensory impairment but not in older adults with late-life sensory loss. We compared associations between visual acuity and cognitive functioning in hearing-impaired older adults (HI), and sensory-unimpaired controls (UI). We expected stronger associations in the HI group as compared with the UI group. DESIGN: Our study sample was drawn from the pools of outpatients from regional university clinics and city registries and consisted of n = 266 older adults (mean age = 82.45 years, SD = 4.76 years; HI: n = 116; UI: n = 150). For the assessment of cognitive performance, multiple established tests (e.g., subtests of the revised Wechsler Adult Intelligence Scale) were used. Moreover, objective visual acuity (distance vision) was assessed. RESULTS: As expected, bivariate correlations between vision and cognitive abilities were stronger in the HI group compared with the UI group. In regression models controlling for age, sex, education, subjective health and number of chronic diseases, distance visual acuity was a significant predictor of general cognitive ability in the HI group only. CONCLUSIONS: Our findings suggest that visual acuity may play an important compensatory role for maintaining cognitive ability when hearing impairment sets in, which may reflect an adaptive process of late-life sensory compensation.

Eye Pain and Dry Eye in Patients with Fibromyalgia.

Objectives: The aim of this study was to examine visual function and eye symptoms in fibromyalgia patients, with a particular focus on dry eye syndrome and eye pain. Methods: A tertiary care center-based cross-sectional study was carried out in chronic musculoskeletal pain patients diagnosed with fibromyalgia. Chronic musculoskeletal pain patients without fibromyalgia were enrolled as a comparison group. Self-reported eye pain was investigated with the McGill pain questionnaire and the numeric rating scale. In addition, we assessed corrected visual acuity, vision-related quality of life, and self-reported dry eye syndrome. Results: A total of 90 musculoskeletal pain patients were included, with 66 patients fulfilling American College of Rheumatology 1990 criteria for fibromyalgia. Sixty-seven percent (95% confidence interval [CI] = 56%-78%) of the fibromyalgia patients reported eye pain, and 62% (95% CI = 43%-81%) of those were without fibromyalgia diagnosis. Sixty-seven percent (95% CI = 56%-78%) of the fibromyalgia patients reported an experience of dry eye compared with 76% (95% CI = 57%-95%) in the nonfibromyalgia group. Vision-related quality of life was noticeably reduced in both groups. Conclusions: Eye pain and dry eye are common in chronic pain patients, with comparable prevalence in musculoskeletal pain patients with and without fibromyalgia.

Four-year reciprocal relationships between personality and functional ability in older adults with and without sensory impairment: focus on neuroticism and agreeableness.

OBJECTIVES: Personality traits have been found to influence health and functional ability (FA) via multiple pathways. However, personality traits may also change in reaction to constraints in FA, particularly in more vulnerable individuals with high risk of decline in independent functioning in daily life (e.g. older adults with sensory impairment). Therefore, conceptually anchored in the World Health Organization's International Classification of Functioning, Disability and Health (ICF model), this study investigated reciprocal relationships between personality, focusing on neuroticism and agreeableness, and indicators of FA (i.e. activities of daily living and subjective autonomy) as well as the potentially moderating role of sensory impairment status. METHOD: The study sample consisted of 387 older adults (mean age at T1: M = 82.50 years, SD = 4.71 years) who were either sensory impaired (SI; i.e. visually or hearing impaired) or sensory unimpaired (UI). A total of 168 individuals were reassessed four years later. RESULTS: Depending on sensory status, personality acted both as predictor and as outcome of FA. Neuroticism was more strongly related with later FA outcomes in SI than in UI individuals. FA variables, in turn, were significant predictors of later neuroticism in UI older adults only and of later agreeableness in SI individuals only. CONCLUSION: These findings suggest that the late-life personality-FA interplay needs to be considered bidirectional, and the direction of associations varies systematically as a function of sensory impairment status.

Cross-sectional and longitudinal relationship between neuroticism and cognitive ability in advanced old age: the moderating role of severe sensory impairment.

OBJECTIVES: Gaining a comprehensive picture of the network of constructs in which cognitive functioning is embedded is crucial across the full lifespan. With respect to personality, previous findings support a relationship between neuroticism and cognitive abilities. However, findings regarding old age are inconsistent. In particular, little is known about potentially moderating variables which might explain some of the inconsistency. Our aim was to examine the moderating effect of severe sensory impairment on cross-sectional and longitudinal associations between neuroticism and cognitive functioning. METHOD: The study sample consisted of 121 visually impaired (VI), 116 hearing impaired (HI), and 150 sensory unimpaired older adults (UI). Mean age was 82.50 years (SD = 4.71 years). Neuroticism was assessed by the NEO Five Factor Inventory, and multiple established tests were used for the assessment of cognitive performance (e.g., subtests of the revised Wechsler Adult Intelligence Scale). RESULTS: Bivariate correlations and multi-group structural equation models indicated stronger relationships between cognitive abilities and neuroticism in both sensory impaired groups (VI and HI) compared to UI older individuals. This relationship was attenuated but still significant in both sensory impaired groups when controlling for age, education and health (number of chronic conditions). In cross-lagged panel models, higher baseline neuroticism was significantly associated with lower cognitive performance four years later in VI and HI individuals. CONCLUSION: Our results suggest that sensory impairment moderates both cross-sectional and longitudinal associations between neuroticism and cognitive function in advanced old age.

Feeling older, feeling pain? Reciprocal between-person and within-person associations of pain and subjective age in the second half of life.

Experiencing pain in middle adulthood and old age might be interpreted as a sign of aging and make people feel older, whereas feeling older has behavioral, motivational, and physiological consequences that might increase the risk of pain. We investigated between-person and within-person associations between pain, subjective age, and chronological age in middle-aged and older adults. Data from the German Ageing Survey were used (n = 13,874 who provided more than 32,000 observations, baseline mean age = 62.3 years). The observation period comprised up to 13 years (M = 4 years) and five (M = 2.4) measurement occasions. Based on the longitudinal multilevel regression models, we found significant between-person and within-person effects in both directions, which were small but robust when controlling for sociodemographic variables, depressive symptoms, and number of chronic diseases. At the between-person level, participants reporting overall more severe pain also felt older than others. Likewise, those who felt overall older than others reported more pain. At the within-person level, when participants experienced more pain than they usually do, they also reported feeling older than usual. Likewise, on measurement occasions when participants reported feeling older than usual, they reported more pain than usual. Additionally, those with overall stronger pain exhibited steeper age-related increases in their subjective age than those with less severe pain. Our findings suggest that an older subjective age may operate as both antecedent and consequence of pain, and pain might prompt a steeper increase in subjective age over time.

Postponing old age: Evidence for historical change toward a later perceived onset of old age.

"At what age would you describe someone as old?" Perceptions of when old age begins might be prone to upward shifts because of historical increases in life expectancy and in retirement age, as well as because of better psychosocial functioning in later life. We investigated historical changes in within-person trajectories of the perceived onset of old age using data from 14,056 participants who entered the German Ageing Survey at age 40-85 years and who completed up to eight assessments across 25 years. Using longitudinal multilevel regression models, we found that at age 64, the average perceived onset of old age is at about age 75 years. Longitudinally, this perceived onset age increased by about 1 year for every 4-5 years of actual aging. We also found evidence for historical change. Compared to the earliest-born cohorts, later-born cohorts reported a later perceived onset of old age, yet with decelerating trend among more recent birth cohorts. Within-person increases of the perceived onset of old age were steeper in later-born cohorts. The described cohort trends were only slightly reduced when controlling for covariates. Being younger, male, living in East Germany, feeling older, reporting more loneliness, more chronic diseases, and poorer self-rated health were each associated with a perceived earlier onset of old age. Our results suggest that there is a nonlinear historical trend toward a later perceived onset of old age, which might have meaningful implications for individuals' perspectives on aging and old age.

Successful Aging and Subjective Aging: Toward a Framework to Research a Neglected Connection.

Research related to subjective aging, which describes how individuals perceive, interpret and evaluate their own aging, has substantially grown in the past two decades. Evidence from longitudinal studies shows that subjective aging predicts health, quality of life, and functioning in later life. However, the existing literature on successful aging has mostly neglected the role of subjective aging. This paper proposes an extended framework of successful aging linking subjective aging conceptually and empirically to Rowe and Kahn's (1997) three original key criteria of successful aging (i.e., avoiding disease and disability, maintaining high cognitive and physical function, and engagement with life). A particular focus is placed on subjective aging as an antecedent of successful aging. A review of the empirical subjective aging literature shows that subjective aging concepts consistently predict all three of Rowe and Kahn's criteria of successful aging. Mechanisms underlying these relations are discussed at three levels, namely psychological, behavioral, and physiological pathways. The proposed addition also takes into consideration the interconnections between subjective aging and successful aging throughout the lifespan and across historical time. Finally, we discuss the importance of facilitating successful aging through systematic interventions that support more positive views of aging at the individual and societal level.

Increasing pain prevalence and intensity among middle-aged and older adults: Evidence from the German Ageing Survey.

OBJECTIVE: Pain is a very common chronic condition in late life that is associated with poorer quality of life and greater functional restrictions. Little is known regarding temporal trends in pain prevalence and pain intensity. Therefore, we estimated trends in pain prevalence and intensity over time among German middle-aged and older adults. METHODS: We used two independent samples drawn in different years from the German Ageing Survey, which is a nationwide population-representative study with a cohort-sequential design. Specifically, a sample of individuals aged 40-85 years who were assessed in 2008 (n = 5961) was compared with a sample of individuals with the same age range who were assessed in 2014 (n = 5809). Individuals were asked if and to what extent they had experienced constant or recurrent pain within the past four weeks. χ2 tests and regression analyses were computed. RESULTS: In 2008, about 44% of all individuals reported suffering from at least very mild pain. In 2014, this proportion was higher by about 7%. Controlling for chronological age, gender, education, region of residence (West vs. East Germany), depressive symptoms, chronic diseases, BMI, and physical activity, the difference in pain prevalence and pain intensity between the samples remained statistically significant. CONCLUSION: Our data suggest an increase in the prevalence and intensity of pain among middle-aged and older German adults between 2008 and 2014, which remained statistically significant when controlling for socio-demographic and health-related indicators. Further research is needed to identify the factors underlying this increasing pain prevalence and pain intensity in order to counteract this negative temporal trend.

Between-person and within-person associations among sensory functioning and attitude toward own aging in old age: Evidence for mutual relations.

Late-life hearing loss and vision loss might prompt more negative attitudes toward one's own aging because older adults may interpret impaired sensory functioning as a sign of aging. At the same time, more positive attitudes toward own aging might, via various mechanisms, be associated with better sensory functioning. We investigated how objective hearing and vision are associated with attitude toward own aging (ATOA) over time. Our sample comprised 497 participants from the Berlin Aging Study (mean baseline age: 85.15 years, SD = 8.58 years) who provided up to six observations over an average time span of 3.73 years (range 0-15 years). We computed longitudinal multilevel regression models, specifying vision, hearing, and age as within-person and between-person predictors of ATOA, and ATOA and age as between- and within-person predictors of vision and hearing. Covariates were sex, socioeconomic status, suspected dementia, chronic physical diseases, and depression. Significant within-person age effects indicated that vision and hearing declined over time, and ATOA became less favorable over time. At the between-person level, we found that participants with a more favorable ATOA exhibited better hearing, but not better vision, at baseline. Between-person associations of vision and hearing with ATOA were not significant. At the within-person level, there was only one significant effect across all models: On measurement occasions when individuals' vision was better, they also reported more favorable ATOA. This association was stronger among older individuals. Improving prevention and treatment of vision loss could thus help older adults to maintain positive views on their own aging.

Middle-aged and older adults' psychosocial functioning trajectories before and during the COVID-19 pandemic: Evidence for multidirectional trends.

So far little is known with regard to the impact of the COVID-19 pandemic on changes in psychosocial functioning of middle-aged and older adults across multiple indicators, interindividual differences in these changes, as well as the extent to which pandemic-related changes are temporary or not. We investigate different domains of psychosocial functioning (views on aging: attitude toward own aging [ATOA] and subjective age; subjective well-being: life satisfaction and depressive symptoms; health: self-rated health) across up to 7 years (prepandemic measurement occasions: 2014 and 2017; peri-pandemic measurement occasions: Summer 2020 and Winter 2020/2021) among middle-aged and older adults (n = 10,856; Mage in 2014 = 64.3 years, SD = 11.58), based on data of the German Ageing Survey. Longitudinal multilevel regression models revealed that mean-level change toward more negative ATOA over time was aggravated by an additional shift toward more pessimistic ATOA in Summer 2020. In contrast, the mean-level change toward older subjective ages over time was interrupted by a shift toward younger subjective ages in Summer 2020. This shift was more pronounced among chronologically younger individuals. Depressive symptoms remained on average stable over time, but there was a temporary increase in Summer 2020. No pandemic-related change was observed for life satisfaction and self-rated health. Our findings suggest that different psychosocial functioning indicators reveal a different susceptibility to "COVID-19 effects," but all changes were temporary, potentially reflecting processes of adaptation. We discuss our results in the context of established theories, such as socioemotional selectivity theory or set-point theory of well-being.

Contextual determinants of subjective age in midlife and old age: The example of daily variations in COVID-19 infection rates.

Feeling younger than one's age reflects a process of age-group dissociation that is frequently activated when belonging to one's age group has negative connotations. Regarding the Corona pandemic, time periods with a higher number of individuals infected with coronavirus disease (COVID-19) might have elicited younger subjective ages, particularly among older adults as they belonged to a "COVID-19 risk group." We investigated the subjective age of n = 233 German individuals aged 47-94 years who were assessed between June and September 2020. COVID-19 cases in Germany were considerably rising from August 2020 on. We were able to confirm an association between a higher infection rate and a younger subjective age; individuals assessed in June, July, August, and September felt on average 9.2%, 9.6%, 13.2%, and 19.2% younger than their chronological age. Controlling for subjective age assessed prior to the pandemic, current depressive symptoms and health concerns, as well as for age, gender, and education, the effect of month of assessment on subjective age remained significant. Also, the number of new COVID-19 infections reported on each individual's day of assessment was a significant predictor of subjective age. The association between a higher infection rate and a younger subjective age was stronger among individuals who were chronologically older and those who reported stronger health concerns. Our findings thus suggest that individuals-particularly those who are older and those who are more worried about their health-feel younger at times when COVID-19 infection rates are higher, which might be a mechanism to cope with the virus threat.

Awareness of Age-Related Changes Among Middle-Aged and Older Adults: Longitudinal Trajectories, and the Role of Age Stereotypes and Personality Traits.

Awareness of Age-Related Change (AARC) describes to what extent people become aware of changes which they attribute to getting older. So far little is known regarding how different AARC dimensions change over time, to what extent these changes in different domains of AARC gains and losses are interrelated, and which predictors account for inter-individual differences in within-person longitudinal trajectories. Specifically, the extent to which individuals perceive age-related gains and losses might be shaped by their chronological age, their personality as well as by their general views on aging (i.e., their age stereotypes). We investigated changes in global and domain-specific AARC gains and losses over about five years in a sample of originally N = 423 participants aged 40 to 98 years at baseline. We analyzed the role of personality traits and age stereotypes for levels and changes of AARC, taking into account participants' age at baseline and controlling for gender, education, and subjective health. Based on longitudinal multilevel regression models, we observed mean-level declines in most AARC gain domains. In contrast, perceived general AARC losses, as well as AARC losses in health and physical functioning, in cognitive functioning and in social-cognitive/socio-emotional functioning remained, on average, stable over time. Baseline scores on AARC gains (global scale) were higher among individuals with higher neuroticism, openness, conscientiousness and more positive age stereotypes. Additionally, the association of higher neuroticism with higher AARC gain scores was stronger among individuals with more positive age stereotypes. Higher neuroticism and more negative age stereotypes also predicted higher baseline scores on AARC losses (global scale). At the same time, higher neuroticism was associated with a steeper decrease in AARC loss perceptions over time. Most of the intercorrelations within the intercepts and within the intra-individual trajectories of the different AARC domains were positive, but small in size. Our findings show the importance of considering trajectories of age-related gains and losses in parallel and across multiple developmental domains when investigating the subjective perception of the aging process. They also suggest that personality traits and general age stereotypes are related with individual experiences of aging.

Trajectories of Pain in Very Old Age: The Role of Eudaimonic Wellbeing and Personality.

Pain is common in very old age and in the last years prior to death. However, little is known regarding longitudinal trajectories of pain in very old age and at the end of life. Moreover, whereas medical and morbidity-related factors contributing to pain are established, the role of psychosocial factors, such as eudaimonic wellbeing or personality as potential determinants of late-life pain trajectories has so far not been sufficiently investigated. We used data from the LateLine project. The sample consisted of n = 118 very old adults (M = 90.5 years, SD = 2.8 years) who were living alone at baseline and who had died between 2009 and 2021. They took part in up to 16 measurement occasions (M = 5.2, SD = 4.7, range 1-16) within an observational interval of 7 years. Assessment of pain was based on the SF-36 bodily pain subscale. Key indicators of eudaimonic wellbeing (autonomy, environmental mastery, and purpose in life) as well two of the Big Five personality traits (neuroticism and extraversion) were included as predictors. We controlled in all analyses for gender, education, subjective health, and depressive symptoms. Contrasting pain trajectories over chronological age (time since birth) vs. time to death, a time-to-death-related model resulted in a better model fit and accounted for a larger amount of pain variability than the age-related model. Mean-level change in pain, both over age and time to death, was not significant, but there was substantial interindividual variability in intraindividual trajectories. Age-related change in pain was significantly predicted by autonomy and neuroticism, with increasing pain among those who had lower initial autonomy scores and higher initial neuroticism scores. With regard to time-to-death-related trajectories of pain, higher purpose in life as well as lower extraversion at baseline predicted less increase or even steeper decrease in pain with approaching death. Our findings suggest that, despite overall mean-level stability in pain both over age and time to death, there is a substantial proportion of individuals who reveal deterioration in pain over time. Regarding the role of psychosocial predictors, personality traits and eudaimonic wellbeing are related with late-life pain trajectories both over age and time-to-death.
