Effects of Persistent Depression on Recall Memory are Moderated by Subjective Age Levels: Evidence From Community-Dwelling Older Adults

Results concerning memory performance in older adults with persistent-depression versus other depressive states (i.e., no-depression, past-depression and current-depression) are disparate. This study examined if persistent-depression is linked with impaired memory (measured by recall), and whether this link is moderated by one's feeling older or younger (subjective age). The study used data from waves 5 and 6 of SHARE-Israel (Survey of Health, Ageing and Retirement in Europe), collected in 2013 and 2015. This representative sample focuses on adults aged 50 and above (N = 1254, mean age = 68.4 ± 9.02). Each wave assessed depression, immediate and delayed recall, fluency and numeracy; subjective age was assessed only at 2015. The main moderation effect was analysed with a hierarchical regression analysis. Memory impairments in the persistent-depression group were evident only for those feeling older. There were no effects of subjective age on fluency and numeracy tasks. Limitations include usage of self-report measures to assess depression, as well as applying a minimal inter-wave duration (2 years) to assess persistent depression. Results are aligned with a resource-stress account of subjective which claims that one's subjective age refelcts a ratio of resoucres-to-stress. Implications suggest that challenges of ageing in the shadow of depression can be compounded by feeling older, that memory (vs. other cognitive tasks) may be uniquely linked with subjective age, and that feeling older is a potential risk factor for impaired memory in persistent-depression. The importance of possible interventions aimed at lowering subjective age are mentioned.

Age differences in the influence of self-esteem and emotional regulation on memory

Emotion regulation (ER) comprises the processes that recognize, monitor, evaluate, and modify emotional reactions. Although ER refers to events that stem from internal or external situations, few studies have examined the effect of intrinsic emotional states on ER processes deployed on external stimuli. The present research investigated, in old- vs. young adults, the influence of state self-esteem (internal condition) in employing ER strategies while implicitly memorizing negative-valence pictures (external condition). State self-esteem was manipulated by giving random feedback (positive/negative) to a demanding cognitive task. Participants then saw 20 photographs and were asked to reappraise half of them and distract themselves from the other half. They were given a recognition task following a short delay with 20 old photographs and 20 new ones. Results indicated that young people with high self-esteem remembered the reappraised pictures better than the distracted ones. In the low self-esteem state, young adults remembered the distracted photographs better than the reappraised ones. In contrast, in old adults low self-esteem resulted in better recognition than high self-esteem, regardless of the regulation strategy. Thus, only among young participants did emotion regulation strategies moderate the effect of self-esteem on memory for negative emotional images. These findings highlight the intricate interplay between different ER strategies and their relative importance across various stages of life.

Feeling Younger on Active Summer Days? On the Interplay of Behavioral and Environmental Factors With Day-to-Day Variability in Subjective Age

Background and Objectives

Subjective age, that is, how old people feel in relation to their chronological age, has mostly been investigated from a macro-longitudinal, lifespan point of view and in relation to major developmental outcomes. Recent evidence also shows considerable intraindividual variations in micro-longitudinal studies as well as relations to everyday psychological correlates such as stress or affect, but findings on the interplay with physical activity or sleep as behavioral factors and environmental factors such as weather conditions are scarce.

Research Design and Methods

We examined data from 80 recently retired individuals aged 59-76 years (M = 67.03 years, 59% women) observed across 21 days. Daily diary-based assessments of subjective age, stress, affect, and sleep quality alongside physical activity measurement via Fitbit (steps, moderate-to-vigorous physical activity) and daily hours of sunshine were collected and analyzed using multilevel modeling.

Results

Forty-four percent of the overall variance in subjective age was due to intraindividual variation, demonstrating considerable fluctuation. Affect explained the largest share in day-to-day fluctuations of subjective age, followed by stress and steps, whereas sunshine duration explained the largest share of variance in interindividual differences.

Discussion and Implications

In our daily diary design, subjective age was most strongly related to self-reported affect as a psychological correlate. We, however, also found clear associations with objective data on daily steps and weather. Hence, our study contributes to contextualizing and understanding variations in subjective age in everyday life.

Understanding Health, Subjective Aging, and Participation in Social Activities in Later Life: A Regional Finnish Survey

To understand health and well-being in later life, it is vital to consider the meaning of subjective aging. This study aimed to explore how perceived health, self-perceptions of aging, and participation in social activities relate to each other among older persons in the Bothnia region and Åland islands in Finland. Data were analyzed using Spearman's and polychoric correlation and multinomial logistic regression analyses. The perceived good health and the younger physical, psychological, and social dimensions of subjective age were found to be associated with each other and with participation in social activities outside one's home.

The Relationship Between Older Adults' Subjective Age and Perceived Effort on Cognitive Tasks

BACKGROUND

Although engagement in cognitively-demanding activities is beneficial for older adults, research suggests that older adults may be less motivated to engage in these types of activities because of the increased age-related costs associated with task engagement and their perceptions of the task demands.

METHODS

Across three studies, we investigated if older adults' subjective age predicted their perceptions of effort over the course of a working memory task. Younger and older adults reported their subjective age and then completed an increasingly difficult series of working memory trials, indicating perceived task demands and effort after each trial.

RESULTS

Results from all three studies showed that there was no age difference in performance or in perceptions of task difficulty, contrary to previous results. Also, there was no significant association between older adults' subjective age and perceived effort, suggesting that subjective age may not be a reliable predictor of perceptions of task demands in older adults.

DISCUSSION

Participant characteristics and the testing environment may play a role in determining the relationship between subjective age and perceived effort.

What does feeling younger or older than one's chronological age mean to men and women? Qualitative and quantitative findings from the PROTECT study

OBJECTIVE

We explored which factors are associated with subjective age (SA), i.e. feeling younger, the same as, or older than one's chronological age, and whether these factors differ between men and women and between two age sub-groups.

DESIGN

Cross-sectional study using qualitative and quantitative data for 1457 individuals (mean age= 67.2 years).

MAIN OUTCOME MEASURES

Participants reported how old they feel they are and provided comments in relation to their SA judgments.

RESULTS

By using content analysis participants' comments were assigned to 13 categories, grouped into three higher-order categories (antecedents of age-related thoughts, mental processes, and issues when measuring subjective age). SA may result from the interaction between factors that increase or decrease age-related thoughts and mental processes that individuals use to interpret age-related changes. Chi-squared tests show that individuals reporting an older SA are more likely to experience significant negative changes and to engage in negative age-related thoughts than individuals reporting an age-congruent SA or a younger SA. Women experience a more negative SA and more age-salient events than men.

CONCLUSION

Individuals reporting an older SA may benefit from interventions promoting adaptation to negative age-related changes. There is the need to eradicate negative societal views of older women.

Cross-Sectional and Longitudinal Associations between Subjective Sleep Difficulties and Self-Perceptions of Aging

BACKGROUND

Only one study has explored the associations of subjective sleep difficulties with self-perceptions of aging. It focused on a global indicator of self-perceptions of aging (subjective age) despite individuals reporting different experiences of aging in relation to different life domains. The concept of awareness of negative age-related change, capturing perceived losses across five domains (e.g., physical health, cognition), may be more appropriate when relating subjective sleep difficulties to self-perceptions of aging. We examined whether nine different indicators of subjective sleep difficulties predict levels of awareness of negative age-related change and subjective age, measured concurrently and one year later, while controlling for covariates (mood and daily function).

PARTICIPANTS/METHODS

We used data from the PROTECT cohort study; 4,482 UK residents (mean age = 66.1; SD = 6.9) completed measures of awareness of age-related change, subjective age, mood, daily function, and subjective sleep difficulties.

RESULTS

Based on linear regression analyses, poorer quality of sleep, lower alertness after awakening, satisfaction with sleep, depth of sleep, more frequent early awakening, difficulty falling asleep, more times awake during a night, fewer hours of sleep during the night and more hours of sleep during the day predicted higher awareness of negative age-related change at baseline and follow-up (p< .001). Associations were small in size. Associations between subjective sleep difficulties and subjective age were either negligible or statistically non-significant.

CONCLUSIONS

Although subjective sleep difficulties are one of the many factors associated with awareness of negative age-related change, addressing sleep difficulties, alongside negative mood, and poor daily functioning, may promote a small additional increase in positive self-perceptions of aging.

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.

Stuck in the Present: A Human Lack of Ability to Visualise (Different) Needs in the Future May Hamper Timely Implementation of AAL and Supportive Technology

Cities face an evident demographic change, making assistive technologies (AAL) an interesting choice to support older adults to autonomously age in place. Yet, supportive technologies are not as widely spread as one would expect. Hence, we investigate the surroundings of older adults living in Vienna and analyse their "socio relational setup", considering their social integration and psychophysical state compared to others (health, fitness, activeness, contentedness). Method: Our data included 245 older adults (age: M = 74, SD = 6654) living in their own homes (2018-2020 with different grades of needing support). We calculated univariate and multivariate models regressing the socio-relational setup on the change of routines, technology attitude, mobility aid use, internet use, subjective age, openness to move to an institutional care facility in the future, and other confounding variables. Results: We found a strong correlation between all categories (health, fitness, activeness, contentedness) of older adults comparing themselves to their peers. Among others, they are significantly related to institutional care openness, which implies that participants who felt fitter and more active than their peers were less clear in visualising their future: unpleasant circumstances of ageing are suppressed if the current life circumstances are perceived as good. This is an example of cognitive dissonance.

Self-perceptions of ageing and perceived health status: the mediating role of cognitive functioning and physical activity

There is evidence that perceived health status is relevant for older adults' wellbeing, and at the same time perceived health status can be influenced by self-perceptions of ageing. There is a lack of studies on the relationship between these variables. The aim of this study was to explore attitudes towards ageing and self-perceptions of ageing among Spanish middle-aged and older people, and to identify possible mediators in the relationship between self-perceptions of ageing on perceived health status. The sample comprised 1,124 individuals from 50 to 98 years old (mean = 64.84, standard deviation = 10.12) from the Ageing in Spain Longitudinal Study database, Pilot Survey (ELES-PS). Almost 70 per cent of the participants stated that old age begins at a specific chronological age and half of them considered that society treats older people with indifference. Self-perceptions of ageing, physical activity, cognitive functioning and age were significant predictors, and together these variables explained 15.9 per cent in the variance of perceived health status. The multiple mediation analysis revealed that self-perceptions of ageing predicted cognitive functioning (B = 0.848, p < 0.01) and physical activity (B = 2.9046, p < 0.001), and mediated the association between self-perceptions of ageing and perceived health status (B = 0.1144, standard error = 0.0147, p < 0.01). Results from this study highlight the importance of perceptions and attitudes towards ageing for older adults' health and wellbeing, thus this study contributes to a better understanding of how these variables are related. In this sense, results from this study can be useful for designing interventions for fostering wellbeing. Addressing negative self-perceptions of ageing and negative attitudes towards ageing can be particularly useful because they are associated with more pessimistic expectancies about the ageing process.

Does grandchild care affect ageing satisfaction? Findings based on a nationally representative longitudinal study

OBJECTIVE

This study seeks to explore the association between grandchild care and Attitudes Towards Own Ageing, assessing whether the commencement of, or ceasing, grandchild care is associated with changes in grandparents' perspectives on ageing.

METHODS

Longitudinal data were drawn from a population-based sample of community-dwelling individuals aged ≥40 years in Germany. The Attitudes Toward Own Ageing subscale of the Philadelphia Geriatric Center Moral Scale (PGCMS) was used to measure Attitudes Towards Own Ageing. To determine whether respondents provided grandchild care, respondents were asked "I'd now like to go on to learn more about your activities and pastimes. Do you supervise other people's children privately, e.g. your grandchildren, or the children of siblings, neighbors, friends or acquaintances?" Symmetric and asymmetric linear fixed effects regressions were used to assess within-person changes longitudinally.

RESULTS

No statistically significant association between providing care for grandchildren and Attitudes Towards Own Ageing was found. Significant associations were found between Attitudes Towards Own Ageing and employment status. Namely, retirement was associated with more positive Attitudes Towards Own Ageing (β = 0.57, p < .001), as was not being employed (β = 0.57, p < .001). A significant association between self-rated health and Attitudes Towards Own Ageing was also found (β = -0.06, p < .001), with poorer self-rated health associated with more negative Attitudes Towards Own Ageing.

CONCLUSION

Our findings suggest that undertaking grandchild care does not shape Attitudes Towards Own Ageing. As our findings did not align with existing evidence on the associations between grandchild caregiving and measures of subjective ageing, further research is required.

The Association Between Views of Aging and Subjective Cognitive Complaints in Older Adults: Findings From Two Samples

This cross-sectional study examined whether views of aging (VoA) relate to subjective cognitive complaints in two separate cohorts of older adults. Ageist attitudes, attitudes to aging (psychological loss, physical change, and psychological growth), subjective age, and subjective successful aging were examined. A moderating effect of chronological age was also examined. Samples included 572 adults aged 50 or older (Sample 1; mean age = 67.63, SD = 11.39, 49.4% female) and 224 adults aged 65 or older (Sample 2; mean age = 81.50, SD = 6.61, 75.3% female). More negative VoA (higher ageist attitudes, lower psychological growth, lower physical change, older subjective age, and less successful aging) were associated with more subjective cognitive complaints after controlling for covariates. An increase in chronological age strengthened some of these associations. Findings suggest that improving dimensions of VoA may have a complementary positive effect on subjective cognitive complaints in older adults.

Quantifying self-rated age

Chronological age, in conjunction with population life tables, is widely used for estimating future life expectancy. The aims of this study are to estimate a subjective ageing indicator, namely self-rated age, and to evaluate its concurrent validity in comparison with other age indicators: subjective survival probabilities, subjective age, and biological age. We use data from the Wave 6 of the Survey of Health, Ageing and Retirement in Europe, Wave 12 of the Health and Retirement Study in the United States, and life tables from the Human Mortality Database. For the statistical analysis we use multinomial regression models. Our results indicate that health status and frequency of physical activities imply similar patterns of self- rated age, subjective survival probabilities, subjective age, and biological age. However, the impact of cognitive function differs by geographical region. Self-rated age can be interpreted as a subjective adjustment that better reflects the ageing process.

Subjective Aging and Objectively Assessed Hearing Function: A Prospective Study of Older Adults

OBJECTIVES

Subjective aging is consistently related to a range of health-related outcomes, but little is known about its relationship with sensory functioning. The present prospective study tested whether subjective age and self-perceptions of aging (SPA) are associated with objective hearing function.

METHODS

Participants were 7,085 individuals aged 50-93 years (60% women, mean = 65.15, standard deviation [SD] = 8.71) from the Health and Retirement Study. Measures of subjective age, SPA, and information on demographic factors were obtained in 2008/2010. Objective hearing function was assessed 8 years later in 2016/2018. Furthermore, potential mediating variables (C-reactive protein, body mass index, physical inactivity, and chronic conditions) were assessed in 2012/2014.

RESULTS

In regression analyses that accounted for demographic factors, older subjective age and negative SPA were associated with lower hearing acuity 8 years later. In addition, 1 SD older subjective age and negative SPA were related to a 9% and 7% higher likelihood of hearing impairment. Mediation analyses revealed that physical inactivity and chronic conditions partially mediated subjective age and SPA associations with hearing acuity. There was little evidence that the link between subjective aging and hearing was moderated by hearing aids and partial support for a moderating role of age.

DISCUSSION

This study provides new evidence that subjective aging is prospectively related to hearing function. Individuals with older subjective age or negative SPA have unfavorable behavioral and clinical profiles that explain part of their lower hearing function. Individuals' experience with their aging process is a marker of risk for impaired hearing.

Subjective age and multiple cognitive domains in two longitudinal samples

OBJECTIVE

Subjective age is consistently related to memory performance and global cognitive function among older adults. The present study examines whether subjective age is prospectively related to specific domains of cognitive function.

METHOD

Participants were drawn from the Health and Retirement Study (HRS, N = 2549, Mean Age = 69.66, SD = 7.36) and the Midlife in the United States Survey (MIDUS, N = 2499, Mean Age = 46.24, SD = 11.25). In both samples, subjective age, depressive symptoms, chronic conditions, and demographic factors were assessed at baseline. Four domains of cognition were assessed 8 years later in the HRS and almost 20 years later in the MIDUS: episodic memory, speed-attention-executive, verbal fluency, and numeric reasoning. HRS also assessed visuospatial ability.

RESULTS

Regression analysis revealed that an older subjective age was related to worse performance in the domains of episodic memory and speed-attention-executive in both samples. The effect size for the difference between a younger and an older subjective age was d = 0.14 (MIDUS) and d = 0.24 (HRS) for episodic memory and d = 0.25 (MIDUS) and d = 0.33 (HRS) for speed-attention-executive. Feeling older was related to lower verbal fluency in HRS (d = 0.30) but not in MIDUS, whereas no association was found with numeric reasoning in either sample. An older subjective age was related to lower visuospatial ability in HRS (d = 0.25).

CONCLUSION

Subjective age is prospectively related to performance in different cognitive domains. The associations between subjective age and both episodic memory and speed-attention-executive functions were replicable and robust over up to 20 years of follow-up.

Subjective age and verbal fluency among middle aged and older adults: A meta-analysis of five cohorts

OBJECTIVES

This study aimed to examine the relation between subjective age and verbal fluency in five large samples of older adults to advance knowledge on the role of subjective age in a complex cognitive function that is an intermediate marker of cognitive impairment and dementia risk.

METHODS

Participants (N > 27,000), aged 32 to 99 years old, predominantly white, were from the Wisconsin Longitudinal Study Graduate (WLSG) and Siblings (WLSS) samples, the Health and Retirement Study (HRS), the Midlife in the United States Study (MIDUS), and the English Longitudinal Study of Ageing (ELSA). They provided complete data on subjective age, demographic factors and verbal fluency. Estimates from each sample were combined in a meta-analysis.

RESULTS

Across each of the five samples and in the meta-analysis, an older subjective age was related to lower performance on the verbal fluency task. This association was independent of chronological age and was not moderated by age, sex, nor education. The difference in fluency between individuals with an older and younger subjective age ranged from d = 0.09 to d = 0.37 across the five samples.

CONCLUSIONS

This study found replicable evidence for an association between an older subjective age and lower verbal fluency, extending knowledge about an intermediate marker of cognitive function.

A Systematic Review and Meta-Analysis of Subjective Age and the Association With Cognition, Subjective Well-Being, and Depression

OBJECTIVES

A systematic review and meta-analysis were conducted to quantify the degree to which subjective age is associated with cognition, subjective well-being, and depression.

METHOD

A systematic search was performed in three electronic social scientific databases, PsycINFO, Scopus, and Web of Science in May 2018. A manual forward and backward citation search of articles meeting the criteria for inclusion, including a mean participant age of 40+ years, was conducted in November 2019. Twenty-four independent data sets were included in the meta-analysis.

RESULTS

Overall, a younger subjective age was related to enhanced subjective well-being and cognitive performance, and reduced depressive symptoms (r = .18). This association was stronger among collectivist (r = .24) than individualist (r = .16) cultures. Mean chronological age across samples (ranging from 55 to 83 years), type of subjective age scoring, and gender did not influence the strength of the overall association. Further analysis revealed that subjective age was individually associated with depressive symptoms (r = .20), subjective well-being (r = .17), and cognition (r = .14), and none had a stronger association with subjective age than the other.

DISCUSSION

The results indicate a small yet significant association between subjective age and important developmental outcomes.

Feeling Younger in Rural Burkina Faso: Exploring the Role of Subjective Age in the Light of Previous Research from High Income Countries

Objectives

Previous research on subjective age (SA), that is, how young or old a person feels relative to their chronological age, has shown that older adults tend to feel younger than they are (by about 15%–20%), but the extent of this effect depends, in part, on their health. However, as most of the studies have been conducted in Western countries, it is unclear how well these results generalize to culturally different samples. Objectives, therefore, were to examine SA in middle-aged and older adults from a very low-income setting in rural Burkina Faso, to examine associations between SA and health/quality of life-related measures, and to compare findings with Western studies.

Methods

Representative, cross-sectional sample of N = 3,028 adults (≥40 years, recruited in 2018) from north-western Burkina Faso. Data included questionnaires on depression (Patient Health Questionnaire-9) and quality of life (World Health Organization Quality of Life scale, including subjective health) as well as performance-based and objective health-related measures (Community Screening Instrument for Dementia as cognitive screening, walking speed).

Results

Respondents felt on average 3% younger (SD = 0.13) than their chronological age, with 48% (95% confidence interval: 0.46–0.50) feeling younger—27 percentage points lower than seen in representative Western studies. Lower depression, better walking speed, cognition, and quality of life were all associated with younger SA.

Discussion

Middle-aged and older adults in Nouna felt less young than similar age groups in Western studies. One of the reasons may be that youthfulness is less of a value outside Western cultures. As in Western studies, parts of the variation in SA can be explained by health parameters.

Subjective age and inflammation risk in midlife adults: Findings from the Midlife in the United States (MIDUS) studies

Recent studies have suggested that subjective age—a subjective evaluation of one's own age—is a promising construct in gerontology that may contribute our understanding of risk for immune dysfunction. Nevertheless, studies documenting the association between subjective age and inflammatory biomarkers remain limited and provide mixed findings. In the present study, we revisited the relation between subjective age and systemic inflammation by utilizing a range of well-established inflammatory biomarkers (C-reactive protein, interleukin-6, fibrinogen, E-selectin, and intercellular adhesion molecule 1) through the collection of fasting blood samples before breakfast. In a large-scale dataset of midlife adults (N = 1800), we found some evidence that an older subjective age is associated with elevated inflammation when indexed by C-reactive protein and fibrinogen, as well as a composite inflammation score. However, these relations were not significant when health variables were controlled for, suggesting that the association between subjective age and systemic inflammation is fully accounted for by better health profiles among those with a younger subjective age. Additionally, the subjective age-inflammation association was influenced by slight variations in the analytic method, highlighting the importance of sensitivity analyses in this area.

•

Subjective age predicted a composite score comprising five inflammatory biomarkers.

•

Subjective age is linked with elevated C-reactive protein and fibrinogen.

•

Subjective age-systemic inflammation link is fully accounted by health profiles.

•

Subjective age predicted the composite score and fibrinogen after correcting for multiple comparisons.

•

Variation in analyses can influence subjective age-inflammation associations.

The Impact of Naturalistic Age Stereotype Activation

Almost self-fulfilling, commonly held negative stereotypes about old age and memory can impair older adults' episodic memory performance, due to age-based stereotype threat or self-stereotyping effects. Research studies demonstrating detrimental impacts of age stereotypes on memory performance are generally conducted in research laboratories or medical settings, which often underestimate memory abilities of older adults. To better understand the "real world" impact of negative age and memory stereotypes on episodic memory, the present research tested story recall performance of late middle-aged and older adults (N = 51) following a naturalistic age stereotype manipulation, wherein every day, newspaper-style materials (comics and puzzles) were either embedded with negative age and memory stereotype stimuli (stereotype group) or neutral stimuli (control group). Furthermore, all participants were tested in favorable, familiar environments. Potential moderators of the stereotype effects, e.g., metamemory beliefs, were assessed at baseline. Current memory evaluation and subjective age, as well as perceived stereotype threat and task-related anxiety, were assessed following the stereotype manipulation as potential mechanisms of the expected stereotype effects. Results suggested a contrast effect, as the stereotype group demonstrated superior story recall performance compared to the control group. Marginally significant moderation effects by age and perceived stereotype threat indicated that stereotype rejection was present for late middle-aged adults but not older adults, indicative of stereotype lift, and for individuals who reported low and average, but not high, levels of perceived stereotype threat. Additionally, a trend suggested more positive memory evaluation for those in the stereotype group who reported awareness of the stereotype stimuli than those who did not notice the stimuli. These results are consistent with other research demonstrating benefits to memory performance in adulthood based on motivational and contextual factors, such as using relevant memory materials and testing in favorable conditions. Moreover, the results of this study contribute to our understanding of individuals' responses to different types of stereotype stimuli, and the differential impact of stereotype manipulations that are subtle versus blatant. Individuals were motivated to counteract negative stereotype effects when conditions were supportive, stereotype presentations were naturalistic, and personal beliefs were positive.

Subjective age, depressive symptoms, and cognitive functioning across five domains

Objective: Younger subjective age predicts better episodic memory and executive functioning performance independent of chronological age. This study examined whether subjective age is associated with performance in five cognitive domains, quantified the extent to which these relationships are mediated by depressive symptoms, and tested whether these associations are moderated by chronological age.Method: Participants in this cross-sectional study included 993 adults aged 65 and older from the Health and Retirement Study's 2016 Harmonized Cognitive Assessment Protocol. Moderated mediation models estimated direct and indirect effects of subjective age on factor scores representing episodic memory, executive functioning, language, visuoconstruction, and speed through depressive symptoms and tested whether associations differed according to chronological age.Results: Depressive symptoms explained 21-32% of the associations between subjective age and language, speed, episodic memory, and executive functioning. Chronological age moderated the indirect effect involving language, such that depressive symptoms were more strongly related to worse language performance at older chronological ages. After accounting for indirect effects, direct effects of younger subjective age remained for language and speed domains.Conclusions: This study extends research on the cognitive correlates of subjective age and demonstrates that depressive symptoms partly mediate these relationships. Subjective age may bemost strongly associated with language among individuals at older chronological ages not because they are more sensitive to the negative mental health impact of feeling older than they are but because they may be particularly vulnerable to the negative effects of depressive symptoms on language ability. Additional longitudinal research is needed to determine whether links between subjective age and cognition are causal versus predictive.

Travel Website Atmospheres Inducing Older Travelers' Familiarity: The Moderating Role of Cognitive Age

In the environment in which an increasing number of older travelers are participating in online tourism platforms, for older travelers who face multiple barriers in using e-commerce, it is essential to identify factors promoting older travelers' website usage for their well-being and sustainable travel industry. This study aims to identify the key factors of website atmosphere for enhancing older travelers' familiarity, investigate the relationship between older adults' website familiarity and revisit intention, and test the moderating role of cognitive age. A web-based survey was conducted, and the sample consisted of 305 US residents 50 years of age and older who had experienced travel websites. The results indicated that three subdimensions of older travelers' website familiarity-informativeness, effectiveness, and entertainment-positively influence their website familiarity. Additionally, the impact of informativeness on website familiarity is stronger for travelers who identify as younger than their chronological age. Moreover, older travelers' familiarity with a website improves their revisit intention. The current study found not only significant travel website atmosphere factors to boost older travelers' participation in online tourism platforms but also significant older travelers' groups depending on their cognitive age perception to magnify the effect of website atmosphere.

Associations of Awareness of Age-Related Change With Emotional and Physical Well-being: A Systematic Review and Meta-analysis

Background and Objectives

This systematic review aimed to synthesize and quantify the associations of awareness of age-related change (AARC) with emotional well-being, physical well-being, and cognitive functioning.

Research Design and Methods

We conducted a systematic review with a correlational random effects meta-analysis. We included quantitative studies, published from January 1, 2009 to October 3, 2018, exploring associations between AARC and one or more of the following outcomes: emotional well-being, physical well-being, and cognitive functioning. We assessed heterogeneity (I²) and publication bias.

Results

We included 12 studies in the review, 9 exploring the association between AARC and emotional well-being and 11 exploring the association between AARC and physical well-being. No study explored the association between AARC and cognitive functioning. Six articles were included in the meta-analysis. We found a moderate association between a higher level of AARC gains and better emotional well-being (r = .33; 95% CI 0.18, 0.47; p <.001; I² = 76.01) and between a higher level of AARC losses and poorer emotional (r = −.31; 95% CI −0.38, −0.24; p < .001; I² = 0.00) and physical well-being (r = −.38; 95% CI −0.51, −0.24; p < .001; I² = 83.48). We found a negligible association between AARC gains and physical well-being (r = .08; 95% CI 0.02, 0.14; p < .122; I² = 0.00). Studies were of medium to high methodological quality.

Discussion and Implications

There is some indication that AARC gains and losses can play a role in emotional well-being and that AARC losses are associated with physical well-being. However, the number of included studies is limited and there was some indication of heterogeneity.

Does older subjective age predict poorer cognitive function and higher risk of dementia in middle-aged and older adults?

As a biopsychosocial marker of aging, subjective age (i.e., the age individuals feel regardless of their actual age) was related to many health issues in the elderly. The purpose of this study is to investigate whether subjective age is associated with subsequent cognition and dementia risk in middle-aged and older adults. Samples were drawn from the English Longitudinal Study of Ageing (ELSA). Participants reported their subjective ages at the baseline (2004/2005), and their cognitive functions were measured after 10 years (2014/2015). Newly diagnosed dementias were recorded between 2006/2007 to 2014/2015. Overall, 6,475 adults aged 50 years or older were included in the current analyses. The relationship between subjective age reported at baseline and cognition assessed ten years later was modeled using multiple linear regression models. Compared to participants who reported a younger subjective age, those who reported an older subjective age were more likely to have poorer cognition after ten years (β = -0.705, P = .002 for memory, β = -1.567, P = .001 for executive function). A Cox proportional hazard regression model suggested that older subjective age was an independent risk factor for incident dementia (HR = 1.737, 95% CI =1.060-2.848). Other than chronological age, subjective age could also be considered as an important predictor for the development of cognitive dysfunction.

The Association between Subjective Age and Motoric Cognitive Risk Syndrome: Results from a Population-Based Cohort Study

OBJECTIVES

The motoric cognitive risk (MCR) syndrome, characterized by cognitive complaints and slower gait speed, is a pre-dementia syndrome associated with dementia and mortality risk. The present study examined whether subjective age, that is how old or young individuals feel relative to their chronological age, is related to concurrent and incident MCR syndrome. A relation between subjective age and MCR will inform knowledge on psychological factors related to dementia risk, identify who is at greater risk, and suggest a potential target of intervention.

METHOD

The study sample was composed of 6,341 individuals aged 65 to 107 years without dementia from the Health and Retirement Study (HRS), a longitudinal study of adults aged 50 years and older. Participants completed measures of subjective age, cognitive complaints, and gait speed and provided information on demographic factors, cognition, physical activity, depressive symptoms, and body mass index (BMI) at baseline in 2008/2010. Incident MCR was assessed four and eight years later.

RESULTS

Controlling for demographic factors, an older subjective age was related to more than 60% higher likelihood of MCR at baseline and to around 50% higher risk of incident MCR over time. These associations remained significant when cognition, physical inactivity, depressive symptoms, and BMI were included in the analytic models.

CONCLUSION

This study provides evidence that how old individuals feel is related to concurrent and incident MCR beyond the effect of chronological age, other demographic factors, physical inactivity, depressive symptoms, BMI, and cognitive functioning.

Is there a rejuvenating effect of (grand)childcare? A longitudinal study on German data

OBJECTIVES

Provision of grandchild care has been found to be associated with a youthful subjective age. Yet, previous studies on this topic were cross-sectional and ignored the increasing proportions of older people growing old without the opportunity to become a grandparent. This study investigates the effects of childcare to grandchildren and to other children on subjective age using panel data.

METHODS

We exploit the longitudinal nature of data from the German Ageing Survey (DEAS) to examine the association between grandparental childcare and care to other children with subjective age, using fixed-effects regression analyses on a sample of 50-85 years old individuals (men: N=11,151; n=3,984; women: N=10,687; n=3,746, where N is the number of observations and n is the number of individuals).

RESULTS

The results from cross-sectional analyses show a "rejuvenating effect" of provision of both types of childcare in later life, especially for women. However, longitudinal analyses find very small and statistically insignificant effects.

DISCUSSION

We show for the first time that both grandchild care and childcare outside the grandparent-grandchild relationship are associated with a youthful subjective age for older people. However, these associations are likely due to selection effects, i.e. unobserved characteristics of people that make them more likely to engage in childcare and are also associated with subjective age. Our results warn against causal interpretation of associations found in previous studies, but also open up new research questions on the role played by childcare other than to grandchildren.

Changes in Subjective Age During COVID-19

BACKGROUND AND OBJECTIVES

To examine the change in subjective age with the emergence of coronavirus disease 2019 (COVID-19). Two competing hypotheses were tested: (a) people felt increasingly older due to the stress generated by the pandemic and (b) people felt increasingly younger due to psychological distancing from older age, a vulnerability to COVID-19.

RESEARCH DESIGN AND METHODS

An age- and sex-stratified sample of adults from across the United States (baseline N = 3,738) was assessed on 3 occasions: before the COVID-19 outbreak in late January/early February and during the outbreak in late March and again in late April. Multilevel modeling analysis examined the change in subjective age and tested potential moderators of individual differences in the trajectory of subjective age.

RESULTS

The average trajectory of subjective age followed a concave curve, with a nadir (feeling younger) during the second assessment in late March. Older age, negative expectations about aging, absence of preexisting conditions, and less stress during COVID-19 were associated with feeling younger but did not predict the rate of change. The only significant predictor of change in subjective age was the belief that the "coronavirus is only a threat to older adults": The more individuals agreed with this statement, the more likely it was that they felt increasingly younger at follow-up.

DISCUSSION AND IMPLICATIONS

Subjective age changed during a global health crisis, with people feeling younger with the emergence of COVID-19. The findings support the hypothesis that subjective age partly reflects a coping process of psychological distancing from older age, the age group most vulnerable to COVID-19.

Sociodemographic predictors of knowledge, mosquito bite patterns and protective behaviors concerning vector borne disease: The case of dengue fever in Chinese subtropical city, Hong Kong

Geographic pattern of dengue fever is changing due to the global environmental and climate changes in the 21st century. Evidence of community's knowledge, mosquito bite patterns and protective behavior practices in non-endemic regions is limited. This study examined the knowledge of dengue, mosquito bite patterns, protective behavior practices and their associated factors in Hong Kong, a non-endemic subtropical city. A population-based random telephone survey (n = 590) was conducted three weeks after the government announcement of a local dengue outbreak in August 2018. Sociodemographic status, awareness, knowledge, protective measures, bite patterns of mosquito were collected. Results indicated high level of community awareness of the local outbreak (95.2%), symptom identification (84.0%) and adoption of at least one mosquito protective measures (nearly 80%). About 40% of respondents reported that they were bitten by mosquitoes during the study period, a high mosquito season in Hong Kong. Mosquito bites were prevalent near grassy area (63.4%), at home (42.6%) and at public transportation waiting spots (39.6%). Younger people (< 25 years old), female, those who lived on lower floors (≤the 6th) and near grassy area were at higher risk of mosquito bites at home. Respondents perceived higher threat of dengue to society were more likely to practice mosquito prevention. While residential factors affected their indoor prevention, other socio-demographic factors affected the outdoor prevention. Practicing prevention behaviors were associated with self-reported mosquito bite at home. Furthermore, the general prevention uptake rate unchanged after the announcement of local dengue outbreak. Although the uptake rate of protective measures during August was high, 40% participants reported they were bitten. Also public locations are more common area for bites, which suggested stronger mosquito prevention and control on public environments and more personal protective behaviors should be advocated.

Feeling Young and in Control: Daily Control Beliefs Are Associated With Younger Subjective Ages

OBJECTIVES

Daily variations in control beliefs are associated with developmental outcomes. We predicted that on days when older adults feel more in control than their personal average, they would also report feeling younger, and explored the relationship in younger adults.

METHOD

A total of 116 older and 107 younger adults completed a 9-day daily diary study. On Day 1 participants reported on demographic variables. On Days 2-9, participants reported their daily subjective age, daily control beliefs, daily stressors, and daily physical health symptoms. All measures were completed online via Qualtrics. Results were analyzed using multilevel models.

RESULTS

Controlling for age, gender, education, daily stressors, daily physical health, and average control, there was a significant main effect of daily control beliefs on daily subjective age. Older adults felt significantly younger on days with a greater sense of control than usual, but this effect was absent in younger adults. For younger adults, average exposure to daily stressors and daily fluctuations in physical health were better predictors of daily subjective age.

DISCUSSION

These findings suggest that higher daily control is associated with younger subjective ages in older adults, whereas other factors may play a more central role in the daily variations of younger adults' subjective ages.

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.

Psychological aging, depression, and well-being

Aging is a multifactorial process, which affects the human body on every level and results in both biological and psychological changes. Multiple studies have demonstrated that a lower subjective age is associated with better mental and physical health, cognitive functions, well-being and satisfaction with life. In this work we propose a list of non-modifiable and modifiable factors that may possibly be influenced by subjective age and its changes across an individual's lifespan. These factors can be used for a future development of individual psychological aging clocks, which may be utilized as a sensitive measure for health status and overall life satisfaction. Furthermore, recent progress in artificial intelligence and biomarkers of biological aging have enabled scientists to discover and evaluate the efficacy of potential aging- and disease-modifying drugs and interventions. We propose that biomarkers of psychological age, which are just as important as those for biological age, may likewise be used for these purposes. Indeed, these two types of markers complement one another. We foresee the development of a broad range of parametric and deep psychological and biopsychological aging clocks, which may have implications for drug development and therapeutic interventions, and thus healthcare and other industries.

An exploration of subjective age, actual age, age awareness, and engagement in everyday behaviors

Considerable research has documented relationships between subjective age and consequential outcomes such as life satisfaction, daily stress, health, and even mortality. Less is known about associations between the age people perceive themselves to be and everyday behaviors that may serve as the paths to broader life outcomes. To begin to fill this gap, this study explored the frequency with which 196 US adults aged 55-87 years engaged in behaviors reflecting nine behavioral domains. Respondents also answered questions about their subjective age, age awareness, and actual age. Results showed that whereas actual age predicted engagement in some behaviors (e.g., retirement activities), subjective age predicted engagement in most others (e.g., personal, social, grooming, body-focused, trend activities), and age awareness predicted participation in yet others (e.g., medical activities). The present findings provide insights both about age-related everyday behaviors, and the ways that several perceptions of age are differentially linked to their occurrence.

Day-to-Day Variability in Subjective Age and Ageist Attitudes and Their Association With Depressive Symptoms

Objectives

Evidence of daily fluctuations in subjective age and their association with older adults’ well-being was recently obtained. Yet, neither the simultaneous tracking of two daily views on aging (i.e., daily subjective age and daily ageist attitudes) nor their interactive effect on mental health (i.e., depressive symptoms) has been explored. We hypothesized that (a) at days on which older adults feel older or report high ageist attitudes they would report higher depressive symptoms, (b) combined older subjective age and high ageist attitudes will be associated with the highest daily depressive symptoms.

Method

Community-dwelling older adults (N = 134, mean age = 69.66) completed measures of subjective age, ageist attitudes, and depressive symptoms for 10 consecutive days.

Results

Daily older subjective age and higher ageist attitudes were related to higher depressive symptoms, but there was no combined effect of both on depressive symptoms. There was a significant three-way interaction between subjective age, ageist attitudes, and chronological age, demonstrating the interactive effect of subjective age and ageist attitudes on depressive symptoms only among the old-old respondents. Time-lagged analyses further showed that ageist attitudes during previous days predicted feeling older and more depressed on following days, but not vice versa.

Discussion

Results suggest that old-old individuals are more susceptible to a combination of negative views on aging on daily basis. Findings further support a daily assimilation process, whereby previous-day stereotypes are assimilated and manifested into one’s identity and mental health, so that one feels older and more depressed on subsequent days.

Dynamic awareness of age-related losses predict concurrent and subsequent changes in daily inductive reasoning performance

To address gaps in previous research, we examined daily within-person associations between awareness of age-related change (AARC) and cognitive performance in older adults. One hundred twelve adults aged 60-90 participated in an online daily diary study for nine consecutive days. On Day 1, they reported demographic information. On Days 2-9, they reported daily AARC, subjective age, and stressors and completed three tasks that gauged memory (word recall), perceptual speed (number comparison), and reasoning (letter series), respectively, once per day. Unconditional multilevel models revealed significant within-person fluctuations in daily cognitive performance and daily AARC. Controlling for age, education, health, and daily stressors, daily awareness of age-related losses was negatively associated with letter series scores of the same day and changes from one day to the next. The effects held over and above AARC gains and subjective age. Dynamic, naturally occurring perceptions of ageing may influence within-person concurrent and subsequent changes in reasoning performance on a daily basis and point to a promising avenue of intervention.

The role of subjective age in sustaining wellbeing and health in the second half of life

Subjective age (SA) is a core indicator of the individual ageing experience, with important consequences for successful ageing. The aim of the current study was to investigate the directions of the longitudinal associations between domains of SA and subjective wellbeing and physical functioning in the second half of life. We used three-wave survey data (2002, 2007 and 2017) spanning 15 years from the Norwegian Lifecourse, Ageing and Generation Study, including 6,292 persons born between 1922 and 1961. SA was measured with felt-age and ideal-age discrepancies, wellbeing with the Satisfaction of Life Scale and physical functioning with the Short-Form 12. Three-wave cross-lagged panel models were applied to assess the temporal relationships between the different domains of SA, life satisfaction and physical functioning, adjusted for age, gender and education. Findings indicated that wanting to be younger was negatively associated with life satisfaction and physical functioning over time. Felt-age discrepancies did not predict subsequent wellbeing or physical functioning. The results did not reveal any evidence for reversed effects, i.e. from functioning or life satisfaction to SA. Our findings support the psychological pathway from satisfaction with age(ing) to subjective wellbeing and physical functioning over time. Small ideal-age discrepancies reflect positive self-perceptions of ageing, which may help to accumulate psychological resources, guide behavioural regulation and support health.

'Feeling younger, remembering better': the effect of experimentally induced subjective age on memory performance among Chinese older adults

Objectives: This study aimed to explore whether experimentally induced younger subjective age can lead to better memory performance among Chinese older adults.Method: A total of 203 participants aged 60-84 years were randomly assigned to three groups. In the positive and neutral feedback groups, participants were told that their memory performance was better than and equivalent to the same-aged peers after an initial memory task, respectively, in contrast to no feedback in the control group. Participants then completed a second memory measure.Results: The results revealed that participants in the positive feedback group felt younger and showed a significant increase in memory performance, whereas participants in the neutral feedback group felt older but also showed a significant increase in memory performance. For participants in the control group, no significant changes in memory performance were observed.Conclusion: It seems that experimentally induced younger subjective age can lead to better memory performance among older adults, providing a promising strategy to maintain memory functioning in old age.

The Role of Attitude Toward Own Aging for Fluid and Crystallized Functioning: 12-Year Evidence From the ILSE Study

Objectives

Aging attitudes have been shown to affect a variety of important developmental outcomes in old age, including memory. Extending previous research, the present study examined long-term effects of attitudes toward own aging (ATOA), relying on a broader range of cognitive abilities in later life.

Method

Data came from the Interdisciplinary Longitudinal Study of Adult Development and Aging (ILSE), with three measurement waves (1993/1994, 1997/1998, and 2005/2006) covering a 12-year interval. Drawing on the older of two available birth cohorts (1930-1932; n = 500), we analyzed the relationship between ATOA and change in fluid versus crystallized abilities based on overall and gender-specific latent change score models, while controlling for education and objective health.

Results

As expected, ATOA predicted change in fluid functioning-but not in crystallized performance-over 12 years. Gender-specific analyses revealed a stronger association between ATOA and decline in fluid abilities for men, even after controlling for health and education.

Discussion

This study adds to the understanding of long-term implications of aging attitudes for cognitive decline trajectories and shows that negative aging attitudes are a risk factor for age-vulnerable cognitive abilities, particularly among men. Further research is needed to better understand the underlying mechanisms of observed relationships.

Social Comparisons of Health and Cognitive Functioning Contribute to Changes in Subjective Age

Objective

As individuals age, they monitor how well they are aging by comparing themselves with their peers. We examined whether such social comparisons contribute to change in one's subjective age over time and whether they mediate the relationship of health and cognitive functioning with subjective age.

Method

A total of 3,427 participants from the Midlife in the United States study were assessed on subjective age on two occasions 10 years apart. Measures of cognition and health were taken at the second wave along with social comparison measures for health and memory.

Results

The results showed that social comparisons of memory and health mediated the relationship between memory performance and level of subjective age as well as the relationship between functional health and subjective age change.

Discussion

The results suggest that those who have better functioning in aging-relevant domains have a more favorable view of themselves compared with others, which in turn predicted a younger subjective age and smaller increases in subjective age over 10 years. When social comparisons were considered, those who had better health and memory and more favorable comparative assessments did not feel that they had aged as much as those who had lower functioning and assessments.

Subjective Age and Memory Performance Among Older Chinese Adults : A Moderated Mediation Model

This study aims to examine the mediating role of learning self-efficacy in the relationship between subjective age and memory performance as well as the moderating role of education in these indirect and direct relationships. A study was conducted with 200 older adults aged 60 to 81 years who completed measures of subjective age, learning self-efficacy, education, and memory performance. Analysis revealed that learning self-efficacy partially mediated the association between subjective age and memory performance. Further analysis found that the indirect associations between subjective age and memory through learning self-efficacy vary as a function of education. Implications and suggestions for future research are discussed.

High-quality relationships strengthen the benefits of a younger subjective age across adulthood

Feeling younger than one's chronological age-a younger subjective age bias-has been consistently linked to healthy aging. However, little is known about conditions under which such benefits are strengthened. In high-quality relationships, partners affirm individuals' self-views and offer support that can encourage individuals to engage in behaviors compatible with their subjective age. Thus, we hypothesized the benefits of a younger subjective age bias would be stronger among adults in high-quality relationships. Hypotheses were supported in a 10-year longitudinal study of married adults (ages 34-84; N > 600): Relationship quality moderated the effect of subjective age bias on memory performance and heart rate variability, such that individuals in higher-quality relationships showed stronger beneficial effects of a younger subjective age bias. Results suggest psychological and relational resources may work together to jointly influence healthy aging. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Forever young? An analysis of the factors influencing perceptions of ageing

Drawing on the revived literature on the subjective dimension of ageing, this paper investigates whether people aged 65+, usually defined as old, do actually feel old and which events they associate with feeling old. Logistic models are used on unique data from the 2013 survey called ‘I Do Not Want to Be Inactive’, conducted on individuals aged 65–74 in Italy (N = 828). It is found that a large proportion of respondents do not feel old at all. The analyses show that women are more likely than men to feel old and to think that society considers them old. While men feel old mainly when they retire, women associate this feeling with loneliness, loss of independence and death of loved ones. Higher-educated people are less likely to associate feeling old with loneliness and boredom than their lower-educated counterparts. The findings have important implications for the conceptualisation of ageing. Most people who are old according to the standard threshold of 65 do not consider reaching this age as a distinctive marker of old age in their lifecourse. This suggests that absolute thresholds for setting the start of old age are questionable. Feeling old seems to be mainly influenced by events, such as retirement and death of loved ones, hinting to the importance of the social construction of ageing in addition to its biological dimension. Researchers and policy makers are encouraged to give more attention to layperson views on ageing.

'It is nothing more than a senior moment': the moderating role of subjective age in the effect of change in memory on self-rated memory

OBJECTIVE

The association between memory performance and self-rated memory is yet to be understood. More specifically, little is known about the factors that lie at the base of self-evaluations of memory in relation to actual changes in memory. In this study, we suggest that subjective age modifies the effect of objective change in memory on self-rated memory.

METHOD

We used two waves of the Health and Retirement Study (N = 4624) to examine whether subjective age moderates the effect of experienced changes in memory between T1 and T2 on self-rated memory at T2.

RESULTS

Our results suggest that subjective age is a significant moderator of the effect of change in memory on self-rated memory. The effect is weaker among those with younger subjective age, and stronger for those with older subjective age.

CONCLUSION

While preserving a young subjective age is usually considered an adaptive strategy, it also has potential negative effects, masking changes in memory performance.

Subjective age and depressive symptoms among Chinese older adults: A moderated mediation model of perceived control and self-perceptions of aging

Although subjective age has been shown to play an important role in older adults' experiences of depressive symptoms, the mediating and moderating mechanisms underlying this relationship have not been adequately examined. The present study aimed to investigate the mediating role perceived control plays between subjective age and depressive symptoms, as well as the moderating role self-perceptions of aging plays in this indirect relationship. To examine this, a cross-sectional study was conducted with 609 Chinese older adults, who completed measures of subjective age, perceived control, self-perceptions of aging, and depressive symptoms. The results indicated that: (1) possessing a younger subjective age is significantly associated with less depressive symptoms; (2) perceived control partially mediates the relationship between subjective age and depressive symptoms; and (3) the indirect effect of subjective age on depressive symptoms, through perceived control, is moderated by self-perceptions of aging, while the mediated path is stronger for older adults with less favorable self-perceptions of aging. The findings underscore the importance of identifying the mechanisms that moderate the mediated paths between subjective age and depressive symptoms.

“Shall We Dance?” Older Adults’ Perspectives on the Feasibility of a Dance Intervention for Cognitive Function

We explored perceptions of social dance as a possible intervention to improve cognitive function in older adults with subjective memory complaints. A total of 30 participants (19 females; mean age = 72.6 years; SD = 8.2) took part in the study. This included 21 participants who had self-reported subjective memory complaints and nine spouses who noticed spousal memory loss. Semistructured interviews were conducted, and a thematic analysis was used to analyze the data. Three main themes were constructed: (a) dance seen as a means of promoting social interaction; (b) chronic illness as a barrier and facilitator to participation; and (c) social dance representing nostalgic connections to the past. Overall, the participants were positive about the potential attractiveness of social dance to improve cognitive and social functioning and other aspects of health. In future research, it is important to examine the feasibility of a social dance intervention among older adults with subjective memory complaints.

Does negative information about aging influence older adults' physical performance and subjective age?

This study investigated the way negative stereotypes influence older adults' physical performance and how old they feel mentally and physically. Sixty-four older adults aged 65 years and older performed different physical tasks using a 3D optoelectronic system under a low or high stereotype threat condition. Self-perceptions of aging were considered as a moderator of the effects of threat. Overall, the effects of threat on physical performance were mostly not significant across tasks. However, threat condition influenced older adults' mental subjective age after they had performed the physical tests; people in the high-threat condition felt closer to their chronological age. Threat also influenced participants' physical subjective age, and this effect was moderated by self-perceptions of aging. More precisely, participants in the high-threat condition felt 7% physically older than their chronological age when they had more negative self-perceptions, while participants in the low-threat condition felt 13% younger. No differences emerged for participants who had more positive self-perceptions. The present findings suggest that performing physical tests under stereotype threat might worsen older people's subjective experience of their own aging by making them feel older.

Subjective age and risk of incident dementia: Evidence from the National Health and Aging Trends survey

The present study examines the association between subjective age and risk of incident dementia in a large longitudinal sample of older adults. Participants were adults aged 65 years and older from the National Health and Aging Trends Study (NHATS). Subjective age, covariates, and cognitive status were assessed in 2011 and cognitive status was again assessed in 2012, 2013, 2014 and 2015. Incident dementia was determined based on answers from self and proxy respondents. The analyses included 4262 participants without dementia at baseline. Adjusting for demographic factors and baseline cognition, an older subjective age was related to higher likelihood of incident dementia. This association was partly accounted by depressive symptoms. Beyond the effect of chronological age, feeling older is associated with the risk of incident dementia.

Leisure-Time Physical Activity, Subjective Age, and Self-Rated Memory in Middle-Aged and Older Adults

Memory concerns are common in middle-aged and older adults. This study investigated the relation of leisure-time physical activity to self-rated memory and the possible mediating role of subjective age in this relationship in middle-aged and older adults. Cross-sectional analyses were conducted with a sample of 1,608 middle-aged and older adults from the second wave of the National Survey of Midlife Development in the United States (MIDUS2). In a path analysis conducted with Mplus, a higher level of leisure-time physical activity was associated with a more positive appraisal of memory compared to others of one's age; younger subjective age partially mediated this relationship. Neither gender nor age-group moderated the association. Age, race, education, marital status, health status, and negative affect were controlled for in the analyses. These findings suggest a possible role of physical activity in countering the effects of age stereotypes on perceived memory.
