Personality, self-rated health, and subjective age in a life-span sample: the moderating role of chronological age

Personal views of aging in midlife and older age: the role of personality

Introduction

Personal views of aging (VoA) reflect individuals' perceptions, attitudes, and expectations regarding their aging selves. The present cross-sectional study was aimed at examining whether personality traits, as defined by the Big Five model, are associated with different VoA concepts related to both subjective age and awareness of age-related gains and losses in midlife and older age.

Materials and methods

A sample of 224 participants aged 46-85 years reported their felt age and completed the Awareness of Age-Related Change (AARC) questionnaire, assessing perceptions of age-related gains (AARC-Gains) and losses (AARC-Losses) in various functioning domains, as well as the short version of the Big Five Inventory.

Results

Linear regression models showed that Openness contributed to explain youthful subjective age. Extraversion explained higher AARC-Gains scores, whereas Emotional Stability, along with younger chronological age and perceiving better self-rated health, contributed to explaining lower AARC-Losses scores.

Discussion

These findings confirm the relationship between personality traits and personal VoA. They further suggest that such an association varies depending on the VoA measure considered. They underscore the importance of considering personality among those individual characteristics capable of shaping personal VoA, with implications for the development of tailored interventions and the understanding of the underlying mechanisms linking personal VoA to health and longevity outcomes in midlife and older age.

Association between personality traits and concerns about falling among older patients: the mediating role of subjective age

Background

Older patients are at high risk of falling, and regular assessments of their concerns about falling (CaF) are often recommended. The present study aimed to investigate the association between CaF and personality traits among older patients as well as to elucidate the mediating role of subjective age.

Method

A cross-sectional study was conducted among 407 patients aged over 60 years in a tertiary hospital located in Chengdu, Sichuan Province, from March 2023 to May 2023. Predesigned electronic questionnaires were distributed to collect relevant data. Four different models (both crude and adjusted weighted linear regression models) were constructed based on the confounders. Confounders were gradually put into the models to control for bias and to examine the stability of the correlations. Bootstrap sampling was employed to examine the mediating role of subjective age.

Result

According to the fully adjusted model, neuroticism (β = 0.17, 95% CI: 0.02 to 0.31, p for trend = 0.02), extraversion (β = -0.07, 95% CI: -0.15 to 0.001, p for trend = 0.05), and subjective age (β = 2.02, 95% CI: 1.28 to 2.78, p for trend <0.001) were consistently correlated with CaF. Mediating analysis revealed that extraversion was negatively related with CaF both directly and indirectly, via subjective age [23.2% partial effect, bootstrap 95%CI: -0.024(-0.080, -0.000)]. Higher neuroticism was consistently related to older subjective age (β = 0.002, 95% CI: 0.001 to 0.004, p for trend = 0.006), while higher levels of conscientiousness, openness, and extraversion were consistently correlated with younger subjective age(β = -0.002, p for trend = 0.04; β = -0.003, p for trend = 0.003; β = -0.002, p for trend = 0.0, respectively).

Conclusion

Extraversion and neuroticism were significantly correlated with CaF. Moreover, subjective age partially mediated the relationship between extraversion and CaF. Furthermore, subjective age was found to be associated with both CaF and personality traits. These findings highlighted the important roles of personality traits and subjective age in assessments of CaF and in the development of strategies for preventing falls among older patients.

The reciprocal relationship between prosocial behaviour and self-perceived physical health: The role of positive affect and openness to experience

The present study used a cross-lagged design to explore the bidirectional relationship between adolescents' prosocial behaviour and self-perceived physical health and to explore the mediating role of positive affect and the moderating role of openness to experience. A total of 1525 middle school students (Mage = 12.41, 47% male) in northern China were surveyed for 3 years. The results showed the following: (1) prosocial behaviour at T1 positively predicted self-perceived physical health at T3; and vice versa; and (2) this observed relation between prosocial behaviour and self-perceived physical health was explained by positive affect; (3) the mediating role of positive affect on the path from prosocial behaviour at T1 to self-perceived physical health at T3 was observed only among adolescents with high openness traits. This finding verified the protective effect of prosocial behaviour on the healthy development of the actor.

The prospective relationship between subjective aging and inflammation: Evidence from the health and retirement study

This study tested the prospective associations and potential mediators between subjective aging, indexed by subjective age and self-perceptions of aging (SPA), and a range of inflammatory markers, including C-reactive proteins (CRP) and pro- and anti-inflammatory cytokines among older adults. Participants (N = 6099, 59% women, age range = 50 to 94, Mean Age = 65.32, SD = 8.85) were drawn from the Health and Retirement Study. Subjective age, SPA, and demographic factors were assessed in 2008/2010. Assessments of soluble transformation growth factor-beta 1 (sTGF-β1), interleukin 10 (IL-10), interleukin-1 receptor antagonist (IL-1Ra), interleukin 6 (IL-6), soluble tumor necrosis factor receptors (sTNFR1), and high sensitivity CRP (hsCRP) were measured in 2016. Potential mediators (body mass index, disease burden, physical inactivity, and depressive symptoms) were asssessed at baseline and in 2012/2014. Linear regression analyses indicated that an older subjective age and negative SPA were related to higher level of IL-10, IL-1Ra, IL-6, sTNFR1 and hsCRP. These associations were mediated by higher disease burden and physical inactivity. Negative SPA (but not subjective age) was associated with lower sTGF-β1. The link between subjective aging and inflammatory markers was relatively independent from chronological age. The present study provides new evidence that subjective aging is prospectively associated with inflammation, including systemic inflammation and pro-and anti-inflammatory cytokines.

[Relationship between the subjective age, higher-life function, and new certification as needing long-term care in community-dwelling older adults: The KAGUYA project longitudinal survey of older adults]

AIM

To determine the relationship between the subjective age, higher-life function, and new certification for the need for long-term care among older adults in the community.

METHODS

A mail survey was conducted in 2016 among community-dwelling older adults, and the 2,323 participants who were available for follow-up in 2019 were included in the analysis. Subjective age was evaluated using the following three items in response to the question "Please answer how old you feel you are": "Same as actual age," "Feel younger," and "Feel older." Other assessments included an evaluation of the higher-life function, Geriatric Depression Scale scores, general self-efficacy, and exercise adherence. In addition, at follow-up, we investigated whether or not participants required new certification for the need for long-term care.

RESULTS

At baseline, participants who felt "older than their actual age" had a significantly lower life function and general self-efficacy and were less likely to exercise at least once a week than the other groups. Furthermore, those who felt "older than their actual age" was more likely than the other groups to be newly certified as needing long-term care, while those who felt "younger than their actual age" were less likely to receive new certification. A logistic regression analysis revealed that "feeling older" was a risk factor for being certified as needing long-term care, even after adjusting for other factors (odds ratio= 3.33, 95% confidence interval: 1.02-10.94, p=0.047).

CONCLUSIONS

Among community-dwelling older adults, those with a subjective age exceeding their chronological age were expected to show a decreased life function in the future and an increased risk of needing long-term care.

Personality and subjective age: Evidence from six samples

Subjective age is associated with health-related outcomes across adulthood. The present study examined the cross-sectional and longitudinal associations between personality traits and subjective age. Participants (N > 31,000) were from the Midlife in the United States Study (MIDUS), the Health and Retirement Study (HRS), the National Health and Aging Study (NHATS), the Wisconsin Longitudinal Study Graduate (WLSG) and Siblings (WLSS) samples, and the English Longitudinal Study of Aging (ELSA). Demographic factors, personality traits, and subjective age were assessed at baseline. Subjective age was assessed again in the MIDUS, the HRS, and the NHATS, 4 to almost 20 years later. Across the samples and a meta-analysis, higher neuroticism was related to an older subjective age, whereas higher extraversion, openness, agreeableness, and conscientiousness were associated with a younger subjective age. Self-rated health, physical activity, chronic conditions, and depressive symptoms partially mediated these relationships. There was little evidence that chronological age moderated these associations. Multilevel longitudinal analyses found similar associations with the intercept and weak evidence for an association with the slope in the opposite of the expected direction: Lower neuroticism and higher extraversion, agreeableness, and conscientiousness were related to feeling relatively older over time. The present study provides replicable evidence that personality is related to subjective age. It extends existing conceptualization of subjective age as a biopsychosocial marker of aging by showing that how old or young individuals feel partly reflects personality traits.

Influence of Contact Experience and Germ Aversion on Negative Attitudes Toward Older Adults: Role of Youth Identity

The world’s population is currently aging, and the issue of ageism has become serious worldwide, including in Japan. Negative attitudes toward older adults can have undesirable effects on the mental and physical health of this group. We focused on the effects of contact experience with older adults and germ aversion, or the degree of aversion to infection, on negative attitudes toward older adults. Additionally, we included a moderating variable; youth identity, or the sense of belonging with younger rather than older age groups. An online survey was conducted with Japanese participants (N = 603). We conducted multiple regression analyses and the results showed that the interaction effect between youth identity and contact experience on negative attitudes toward older adults was significant. The findings suggest that contact experience may help in reducing negative attitudes toward older adults among people with low youth identity. The interaction effect between youth identity and germ aversion, however, was not significant. Academic research on the effects of some psychological interventions (e.g., intergenerational social exchange) should pay particular attention to the role of youth identity. Future directions for empirical studies are also discussed.

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.

Experience of Time and Subjective Age When Facing a Limited Lifetime: The Case of Older Adults with Advanced Cancer

Objectives

We addressed two questions: (1) Does advanced cancer in later life affect a person’s awareness of time and their subjective age? (2) Are awareness of time and subjective age associated with distress, perceived quality of life, and depression?

Methods

We assessed patients suffering terminal cancer (OAC, n = 91) and older adults free of any life-threatening disease (OA, n = 89), all subjects being aged 50 years or older.

Results

Older adults with advanced cancer perceived time more strongly as being a finite resource and felt significantly older than OA controls. Feeling younger was meaningfully related with better quality of life and less distress. In the OA group, feeling younger was also associated to reduced depression. Perceiving time as a finite resource was related to higher quality of life in the OA group.

Discussion

Major indicators of an older person’s awareness of time and subjective aging differ between those being confronted with advanced cancer versus controls.

Associations of Agency and Communion With Domain-Specific Self-Perceptions of Aging: A Cross-Sectional Study In Old-Old Adults in Poor Health

A large body of research indicates that self-perceptions of aging (SPA) play an important role for health in later life. Hence, more research on SPA and correlates is needed, especially in old age and poor health, where negative SPA tend to prevail. Recent studies identified personality as an important correlate of SPA in young-old and relatively healthy samples. Thus, we investigated cross-sectional associations of agency and communion with two SPA domains in a sample of old-old adults in poor health (n  =  154; M_age  =  81.55, SD  =  4.56, 58.4% women). In multiple regression analyses, agency and communion were associated with SPA related to ongoing development beyond health. In contrast, only health as a covariate was significantly associated with SPA related to physical losses. Thus, personality may be a resource associated with gain-related SPA, at least for those in poor health and old age.

Psychological Predictors of Perceived Age and Chronic Pain Impact in Individuals With and Without Knee Osteoarthritis

OBJECTIVE

Chronological age is a risk factor in chronic pain; however, aging research supports the premise that physical and psychological health may better predict perceived age. Given the lack of evidence on perceived age in the context of chronic pain, the current study presents novel findings about the relationship between perceived age, chronic pain impact, and psychological function in adults with and without knee osteoarthritis.

METHODS

This secondary analysis was part of an ongoing multisite observational cohort study to understand the progression of knee pain and disability. Community-dwelling adults (N=227) ages 45+ completed measures of trait resilience, trait positive and negative affect, pain catastrophizing, subjective perceptions of age, and the Graded Chronic Pain Scale.

RESULTS

On average, participants reported feeling 10 years younger than their chronological age; however, this effect was attenuated in individuals reporting high-impact pain. Lower perceived age was associated with lower pain impact (low pain/low disability), while higher perceived age correlated with higher pain impact (high pain/high disability) and more adverse psychological effects. Using hierarchical linear regression, high-impact pain and positive affect emerged as statistically significant predictors of perceived age, whereas no differences were observed among trait resilience, negative affect, or pain catastrophizing.

DISCUSSION

These findings highlight the importance of a biopsychosocial approach in understanding the intersection between psychological and physical factors associated with chronic pain. Addressing negative self-perceptions of aging, while simultaneously augmenting positive affect, through psychological therapies may mitigate pain and disability.

Bidirectional relationship between subjective age and frailty: a prospective cohort study

Background

Subjective age refers to how young or old individuals experience themselves to be and is associated with health status, behavioral, cognitive, and biological processes that influence frailty. However, little research has examined the relationship between subjective age and frailty among older adults. This study examined the bidirectional association between subjective age and frailty among community-dwelling older adults.

Methods

We used data from the 2011 to 2015 waves of the National Health and Aging Trends Study. Our sample consists of 2,592 community-dwelling older adults with complete data on main outcome variables. Subjective age was measured by asking participants, “What age do you feel most of the time?” Based on the five phenotypic criteria: exhaustion, unintentional weight loss, low physical activity, slow gait, and weak grip strength, frailty was categorized into robust = 0, pre-frailty = 1 or 2; frailty = 3 or more criteria met. Generalized estimating equation models were used to examine the concurrent and lagged association between subjective age and frailty.

Results

Participants were, on average, 75.2 ± 6.8 years old, non-Hispanic whites (76 %), female (58 %). 77 % of the participants felt younger, 18 % felt the same, and 5 % felt older than their chronological age. About 45 %, 46 %, and 9 % of the participants were robust, pre-frailty and frailty in the first wave, respectively. Generalized estimating equations revealed that an “older” subjective age predicted a higher likelihood of pre-frailty and frailty (OR, 95 % CI = 1.93, 1.45–2.56).

Conclusions

These findings suggest that people with older subjective age are more likely to be pre-frail/frail. Subjective age could be used as a quick and economical screening for those who are potentially frailty or at risk for frailty.

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.

Personality traits relate to chronotype at both the phenotypic and genetic level

INTRODUCTION

Diurnal preferences have been linked to personality but often with mixed results. The present study examines the relationships between sleep timing (chronotype), diurnal preferences, and the Five-Factor Model of personality traits at the phenotypic and genetic level.

METHODS

Self- and informant-reports of the NEO Personality Inventory-3, self-reports of the Munich Chronotype Questionnaire, and DNA samples were available for 2,515 Estonian adults (M_age  = 45.76 years; 59% females). Genetic correlations were obtained through summary statistics of genome-wide association studies.

RESULTS

Results showed that higher Conscientiousness and lower Openness to Experience were significant predictors of earlier chronotype. At the level of facets, we found that more straightforward (A2) and excitement-seeking (E5), yet less self-disciplined (C5) people were more likely to have later chronotypes. The nuance-level Polypersonality score was correlated with chronotype at r = .28 (p < .001). Conscientiousness and Openness were genetically related with diurnal preferences. The polygenic score for morningness-eveningness significantly predicted the Polypersonality score.

CONCLUSION

Phenotypic measures of chronotype and personality showed significant associations at all three of levels of the personality hierarchy. Our findings indicate that the relationship between personality and morningness-eveningness is partly due to genetic factors. Future studies are necessary to further refine the relationship.

Relationship between personality and physical capacities in older adults: The mediating role of subjective age, aging attitudes and physical self-perceptions

Walking speed and muscular strength are two main markers of health in adulthood. Previous studies have shown that personality traits may predict these two outcomes. However, little is known about the mechanisms underlying these relationships. Thus, the present study examined whether personality traits are associated with walking speed and muscular strength through the mediating role of subjective age (how young or old individuals experience themselves to be), attitudes toward aging and physical self-perceptions. Community-dwelling older women (N = 243; M_age = 73.0; SD_age = 6.5) were recruited. For reasons of recruitment feasibility, participants were only older women. They were requested to complete a questionnaire measuring personality, subjective age, attitudes toward aging and physical self-perceptions. Following this, their walking speed and their muscular strength were investigated. Data were analyzed using structural equation modeling. In line with the literature, we extended the associations between extraversion, neuroticism, conscientiousness and walking speed and between conscientiousness, neuroticism, openness and muscular strength. Physical self-perceptions appear to be a robust mediator between personality traits and walking speed whereas attitudes toward aging and subjective age mediated the personality traits/muscular strength relationship. This study provides evidence, for the first time, that the associations between personality traits and physical capacities are different according to the physical capacities investigated. Based on these results, it could be interesting to adapt physical activity interventions to the psychological profile of older adults.

Employable as We Age? A Systematic Review of Relationships Between Age Conceptualizations and Employability

This systematic review aimed to provide an overview of earlier research on the relationships between age conceptualizations (i.e., calendar age, organizational age, lifespan age, psychosocial age, and functional age) and indicators of employability. We have conducted a systematic literature search using PsycINFO, Academic Search Premier, Business Source Complete, CINAHL, ERIC, MEDLINE, and Science Direct. Two raters evaluated the articles and subsequently distinguished k = 41 studies that met the inclusion criteria for this systematic review. Our review revealed that many researchers adopted different operationalizations to measure employability (15 studies were based on an input- or competence-based measure of employability, 23 studies included an output- or labor market-based measure of employability, and three studies included a combination of both measures). Moreover, most studies included calendar age (40 studies, 97.6%) as indicator of aging at work, and were based on a cross-sectional design (34 studies, 82.9%; 17.1% a longitudinal design). Based on the Standardized Index of Convergence (SIC) method, different types of evidence were found for the relationships between age and the employability measures. For relationships between psychosocial age and lifespan age, on the one hand, and employability measures, on the other hand, too few studies were found to draw conclusions. Yet, for relationships between calendar age and labor market-based measures strong consistent negative relationships were found across the studies, and moderately strong positive relationships were found for functional age and labor market- based measures. For organizational age and both competence-based as well as labor market-based measures moderately strong negative relationships were found. We discuss the implications of these results and propose a research agenda for future studies.

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.

The impact of personality traits on medication adherence and self-care in patients with type 2 diabetes mellitus: The moderating role of gender and age

OBJECTIVES

This study aimed to investigate the role of the five-factor model of personality (FFM) and the moderating role of gender and age in predicting medication adherence (MA) and self-care behaviors (SCB) among Iranian patients with type 2 diabetes mellitus (T2DM).

METHODS

This study was conducted on 495 patients with T2DM (73.5% female; n = 364) from two major cities of Iran (Tehran and Qom) in 2019. Pearson's correlation coefficient, multiple regression analysis, and conditional process analysis were performed. P < .05 and P < .10 were considered significant for the relationships and moderation analysis, respectively.

RESULTS

Neuroticism indicated a negative association with MA and SCB. Positive associations were found between MA and personality traits, including extraversion, agreeableness, and conscientiousness, whereas extraversion showed a weak correlation with SCB. According to the covariate-adjusted regression model, neuroticism had a negative effect on MA and SCB. Agreeableness had a positive effect on MA and a negative effect on SCB. However, extraversion exerted a negative effect on MA and a positive effect on SCB. Also, the negative effect of neuroticism on MA was highlighted in women, indicating marginally significant moderation effect. The positive effects of extraversion and conscientiousness on MA were moderated by age. The effect of conscientiousness on SCB was positive in young patients and negative in old patients. No interaction effect was observed between age and gender.

CONCLUSION

This study indicated that neuroticism, extraversion, and agreeableness significantly contributed to MA, but not to SCB. However, the effects were conditioned by age for extraversion and conscientiousness to some extent.

The association between self-compassion and self-rated health in 26 samples

Background

Although there is growing evidence of the relevance of self-compassion for understanding health outcomes, few studies have examined self-compassion in relation to self-reported physical health status, also known as self-rated health (SRH). This study addressed this gap by examining the associations between self-compassion and SRH across multiple samples and after accounting for the contributions of positive and negative affect.

Methods

Data from 26 samples (total N = 6127), comprised of 6 university student, 16 community adult, and 4 chronic illness samples, were included in the current analyses. Participants in each sample completed a survey including measures of self-compassion and SRH. Thirteen samples also completed a measure of positive and negative affect. The associations between self-compassion and SRH were statistically meta-analysed. Moderator analyses were conducted to test whether the associations varied as a function of sample type, age or participant sex. Semipartial correlations were calculated controlling for positive and negative affect in 13 samples and meta-analysed.

Results

Findings indicated that self-compassion was significantly associated with higher SRH across the 26 samples (r_avg = .25; CI: .22, .28). The associations did not however vary significantly across sample types, or as a function of participant sex or age. The meta-analyses of the adjusted effects found that self-compassion remained significantly associated with higher SRH after accounting the contributions of positive (sr_avg = .11; CI: .07, .15) and negative (sr_avg = .25; CI: .06, .15) affect.

Conclusions

The current study demonstrated that self-compassion is robustly associated with higher SRH across 26 samples and that this association remained significant after adjusting for the influence of positive and negative affect in 13 samples. Further longitudinal and experimental research is needed to verify the causal direction between self-compassion and SRH suggested by theory and the current findings.

Relationships of self-perceived age with geriatric assessment domains in older adults with cancer

OBJECTIVES

Older self-perceived age is associated with poor health and higher healthcare utilization in the geriatric population. We evaluated the associations of self-perceived age with geriatric assessment (GA) domain impairments in older adults with cancer.

METHODS

This was a secondary analysis of baseline data from a GA cluster-randomized trial (URCC 13070; PI: Mohile). We included patients aged ≥70 with incurable stage III/IV solid tumor or lymphoma considering or receiving treatment and had ≥1 GA domain impairment other than polypharmacy. Multivariate analyses were used to evaluate the associations of age difference between chronological and self-perceived age (categorized into "feeling younger than chronological age" vs. "feeling the same or older than their chronological age") with GA domain impairments.

RESULTS

We included 533 patients; mean age was 76.6 (SD 5.2). On multivariate analyses, compared to those who felt younger than their chronological age, those who felt the same or older were more likely to have impairments in physical performance [Adjusted Odds Ratio (AOR) 5.42, 95% Confidence Interval (CI) 1.69-17.40)], functional status (AOR 2.31, 95% CI 1.73-3.07), comorbidity (AOR 1.62, 95% CI 1.20-2.19), psychological health (AOR 2.62, 95% CI 1.85-3.73), and nutrition (AOR 1.65, 95% CI 1.20-2.28). They were also more likely to screen positively for polypharmacy (AOR 1.86, 95% CI 1.30-2.65).

CONCLUSIONS

Older adults with cancer who felt the same or older than their chronological age were more likely to have GA domain impairments. Further studies are needed to better understand the relationships between self-perceived age, aging-related conditions, and outcomes in this population.

Subjective Age in Older Korean Americans: The Impact of Functional Disability Mediated by Attitudes Toward Aging

The present study aims to examine how subjective age of older Korean Americans would be affected by functional disability and attitudes toward aging. We hypothesized that (a) both functional disability and attitudes toward aging would have a direct effect on subjective age and (b) the effect of functional disability on subjective age would be mediated by attitudes toward aging. Our analyses of the survey data with 208 community-dwelling Korean Americans aged 60 and older (mean age = 69.6, SD = 7.51) showed that the indirect effect of functional disability on subjective age through attitudes toward aging [-.020 (.009)] was significant (bias-corrected 95% confidence interval [-.039, -.006]). The findings suggest that functional disability fosters negative attitudes toward aging, which in turn leads to the feelings of being older than actual age. Our study suggests ways to preserve and promote positive perceptions of age and aging.

Subjective Age Across the Life Span: A Differentiated, Longitudinal Approach

Objectives

How old people feel compared with their actual age, their so-called "subjective age" (SA), is a central indicator of individual aging experiences and predicts developmental outcomes, such as health and mortality, across the life span. We investigated the multidimensional structure of SA with respect to specific life domains, focusing on domain differences as well as age group differences and age-related changes. Furthermore, we inspected the relationship between SA and how people perceive their future as old persons (future self-views).

Method

We assessed these variables in a sample of 593 persons who completed a questionnaire at two time points 4 years apart (baseline-T1; follow up-T2) and who were aged 30-80 years at T1.

Results

SA differed across life domains and age groups, and the amount of change in SA across time was also contingent on life domain. Future self-views at T1 predicted subsequent changes in SA, with more negative self-views being associated with an increase in SA, especially for middle-aged participants for whom the transition to older age is imminent.

Discussion

Our results provide support for a multidimensional view of subjective aging experiences. They highlight the importance of a differentiated investigation of subjective aging constructs and their relations for understanding how these variables shape the aging process.

The Role of Personality in Becoming Aware of Age-Related Changes

Awareness of age-related change (AARC) refers to an individual's conscious knowledge about the gains and losses resulting from growing older. Personality traits reflect dispositional patterns of behavior, perception, and evaluation and should therefore influence the experience of AARC. The 4.5-year longitudinal study examines this association between personality traits and AARC in a sample of 423 individuals aged 40 to 98 years (M = 62.9 years) using latent change analyses. After controlling for sex, health, and education, a different pattern of associations for cross-sectional vs. longitudinal relations. Cross-sectionally, neuroticism was positively related to AARC losses, whereas openness, conscientiousness, and neuroticism were positively related to AARC gains. Longitudinally, the impact of personality traits on change in AARC was rather limited with only higher conscientiousness acting as a predictor of decreases in AARC losses over time. Overall, the findings add to the existing literature on associations between personality traits and subjective aging. Specifically, the results indicate that personality traits are differentially related to awareness of age-related gains in comparison to awareness of age-related losses.

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).

Though Forced, Still Valid: Psychometric Equivalence of Forced-Choice and Single-Statement Measures

Forced-choice (FC) measures are gaining popularity as an alternative assessment format to single-statement (SS) measures. However, a fundamental question remains to be answered: Do FC and SS instruments measure the same underlying constructs? In addition, FC measures are theorized to be more cognitively challenging, so how would this feature influence respondents’ reactions to FC measures compared to SS? We used both between- and within-subjects designs to examine the equivalence of the FC format and the SS format. As the results illustrate, FC measures scored by the multi-unidimensional pairwise preference (MUPP) model and SS measures scored with the generalized graded unfolding model (GGUM) showed strong equivalence. Specifically, both formats demonstrated similar marginal reliabilities and test-retest reliabilities, high convergent validities, good discriminant validities, and similar criterion-related validities with theoretically relevant criteria. In addition, the formats had little differential impact on respondents’ general emotional and cognitive reactions except that the FC format was perceived to be slightly more difficult and more time-saving.

The associations between objective and subjective health among older adults with type 2 diabetes: The moderating role of personality

BACKGROUND

Objective and subjective health are two powerful constructs which predict morbidity and mortality across a range of conditions including Type 2 Diabetes (T2D). Studies, however, suggest that these two constructs do not necessarily correlate, as some people with poor objective health perceive their health as good, while other people with good objective health perceive their health as poor. We seek to examine the role of personality as a moderator of the associations between objective and subjective health among older adults with T2D, who are likely to experience poor objective and subjective health due to their chronic medical condition.

METHODS

Cross-sectional study of 368 individuals with T2D (72 ± 4 years, 42% women), participating in the Israel Diabetes and Cognitive Decline Study. Personality was conceptualized using the five-factor model (agreeableness, conscientiousness, extraversion, neuroticism, openness). Objective health was operationalized by T2D-related clinical status, cognitive function, and motor ability. Subjective health was assessed using a single self-report question. Hayes' process macro was used for the moderation analyses.

RESULTS

The objective-subjective health associations were stronger among individuals with increased neuroticism (proportion of days covered: p = 0.02; cognitive function: p = 0.003; hand grip: p = 0.02; 3-m walk: p = 0.04) as well as decreased openness (cognitive status: p = 0.04) and agreeableness (3-m walk: p = 0.02).

DISCUSSION

Personality traits, and specifically neuroticism, can modify the associations between objective and subjective health in older adults with T2D. Findings contribute to the understanding of health as a multidimensional construct that encompasses medical and psychological aspects, especially among older adults with a chronic illness.

Influence of Sociodemographic, Behavioral and Other Health-Related Factors on Healthy Ageing Based on Three Operative Definitions

OBJECTIVES

Healthy ageing (HA) is a key concept and highly desirable phenomenon in every ageing and already old societies. The aim of our study was to evaluate the influence of socio-economic conditions as well as life-style and other health-related factors on the WHO definition of HA.

DESIGN, SETTING, PARTICIPANTS

The study used cross-sectional data of the PolSenior Project - nationwide research evaluating different aspects of ageing in Poland - which included 4'653 respondents aged 65 years and over.

MEASUREMENTS

Data were collected by trained interviewers in respondents' homes. Three definitions of HA including or not the participants' chronic conditions were analyzed.

RESULTS

The prevalence of HA appeared as high as 17.6% if none or 1 chronic disease was present and 42.8% if no information about chronic diseases was taken into account. The association between known health predictors (age, marital status, education, income) and HA was observed. Moreover, HA appeared in relation with indicators of physical functioning and lifestyle. There was a strong concordance between HA and the fair self-rated health (OR = 1.87; 1.99, and 2.74 for the 1st, 2nd and 3rd definitions, respectively) and opposite relation with self-reported need for help (OR = 0.15; 0.15; and 0.13, respectively).

CONCLUSIONS

The HA definition based on no functional activity limitations, no cognitive impairment, no depressive symptoms, no more than one disease and being socially active seems to be a useful approach of HA.

Subjective Life Expectancy Among College Students

Establishing healthy habits in college is important for long-term health. Despite existing health promotion efforts, many college students fail to meet recommendations for behaviors such as healthy eating and exercise, which may be due to low perceived risk for health problems. The goals of this study were to examine: (1) the accuracy of life expectancy predictions, (2) potential individual differences in accuracy (i.e., gender and conscientiousness), and (3) potential change in accuracy after inducing awareness of current health behaviors. College students from a small northeastern university completed an electronic survey, including demographics, initial predictions of their life expectancy, and their recent health behaviors. At the end of the survey, participants were asked to predict their life expectancy a second time. Their health data were then submitted to a validated online algorithm to generate calculated life expectancy. Participants significantly overestimated their initial life expectancy, and neither gender nor conscientiousness was related to the accuracy of these predictions. Further, subjective life expectancy decreased from initial to final predictions. These findings suggest that life expectancy perceptions present a unique-and potentially modifiable-psychological process that could influence college students' self-care.

Feeling How Old I Am: Subjective Age Is Associated With Estimated Brain Age

While the aging process is a universal phenomenon, people perceive and experience one's aging considerably differently. Subjective age (SA), referring to how individuals experience themselves as younger or older than their actual age, has been highlighted as an important predictor of late-life health outcomes. However, it is unclear whether and how SA is associated with the neurobiological process of aging. In this study, 68 healthy older adults underwent a SA survey and magnetic resonance imaging (MRI) scans. T1-weighted brain images of open-access datasets were utilized to construct a model for age prediction. We utilized both voxel-based morphometry (VBM) and age-prediction modeling techniques to explore whether the three groups of SA (i.e., feels younger, same, or older than actual age) differed in their regional gray matter (GM) volumes, and predicted brain age. The results showed that elderly individuals who perceived themselves as younger than their real age showed not only larger GM volume in the inferior frontal gyrus and the superior temporal gyrus, but also younger predicted brain age. Our findings suggest that subjective experience of aging is closely related to the process of brain aging and underscores the neurobiological mechanisms of SA as an important marker of late-life neurocognitive health.

The Effects of Subjective Age and Aging Attitudes on Mid- to Late-Life Sexuality

This study examined the effects of subjective age and attitudes about aging on frequency of sex and interest in sexual activity among middle-aged and older adults. Data were drawn from two waves of the Midlife in the United States (MIDUS) study (n = 1,170 adults, mean age Time 1 = 53.70 years, SD = 9.08). Regression analyses were used to investigate the effects of subjective age and attitudes about aging on three measures of sexuality: frequency of sex, perceived quality of sexual activity, and interest in sexual activity, over 10 years. The older participants felt and the less positive their views of aging, the less they rated sexual activity as enjoyable over time. Feeling older (though not attitudes about aging) also predicted less interest in sex. Subjective age and beliefs about aging did not have an impact on frequency of sex. Although frequency of sex was not predicted by subjective aging and aging attitudes, the results suggested that subjective age and stereotypic views on aging may shape the experience of sex in later life.

Subjective Age and Its Correlates Among Middle-Aged and Older Adults

The present study evaluates discrepancies in subjective age as reported by middle-age persons (aged 44-64 years) in comparison to older adults (aged 65 years and older), using a multidimensional definition of the concept. A convenience sample of 126 middle-aged and 126 older adults completed subjective age measures (felt age, desired age, and perceived old age), attitudes toward older adults, knowledge about aging, and sociodemographic questionnaires. Overall, participants reported feeling younger than they actually were and wanting to be younger than their chronological age. Perceived mean for old age was about 69 years. Discrepancies in felt age and desired age were significantly larger for the older group compared to the middle-aged group. Regarding perceived old age, compared to the younger group, older adults reported that old age begins at an older age. Findings suggest that middle-aged and older adults' perceptions regarding themselves and regarding old age in general are independent and need, therefore, separate research and practical attention.

"I WILL SURVIVE" A Construct Validation Study on the Measurement of Sustainable Employability Using Different Age Conceptualizations

Though the importance of sustainable employability throughout people's working life is undisputed, up till now only one attempt for a conceptual definition has been made (van der Klink et al., 2016). Following the suggestions to further refine and improve this definition recently put forward by Fleuren et al. (2016), we propose an approach to sustainable employability that is based on the Ability-Motivation-Opportunity (AMO) framework, and incorporates three indicators: the ability, the motivation, and the opportunity to continue working, respectively. As sustainable employability is considered to be an important aspect of successful aging at work, this study used four different conceptualizations of aging at work to set up convergent and divergent validity of our operationalization of sustainable employability: calendar age, organizational age (job and organizational tenure), functional age (work ability), and life-span age (partner and children). We formulated several hypotheses that were tested by analyzing data from an online survey among 180 employees from Dutch public service organizations who filled out a questionnaire on different age concepts, and their ability, motivation, and opportunity to continue working. Multiple regression analyses were performed, and results showed that the four conceptualizations of aging were differently related to the three indicators of sustainable employability. Life-span age, in terms of having children, had the strongest negative relationship with the ability to continue working, organizational age (i.e., organizational tenure) had the strongest negative relationship with the motivation to continue working, and functional age had the strongest negative relationship with the opportunity to continue working. Moreover, functional age was significantly negatively related to the other two indicators of sustainable employability too, while life-span age appeared to enhance the ability and motivation to continue working (in terms of having children) and the perceived opportunity to continue working (in terms of having a partner). Calendar age was only important for the opportunity to continue working and appeared to have a negative association with this outcome variable. These results lend support to our proposed operationalization of sustainable employability by showing that the three indicators are differently related to different age conceptualizations thus expanding previous research on the conceptualization of sustainable employability.

Felt Age, Desired, and Expected Lifetime in the Context of Health, Well-Being, and Successful Aging

This study examines the interrelations of three different aspects of the subjective age: felt, desired and expected, as well as their relations with the chronological age (CA), health, and psychological well-being variables. Four hundred and twenty-three community-dwelling Croatian adults, aged 60-95 years, participated in the study. All three subjective age measures significantly correlated with the CA. Self-rated health were better predictors of the subjective age compared to the psychological variables. Among psychological variables, successful aging was the only significant predictor of the felt and expected age, while optimism showed to be the only significant predictor of the desired age. Results indicate the importance of some sociodemographic, psychological, and health variables for understanding older persons' subjective age identity and their desires and expectations regarding length of life. Besides the CA, it is very useful to include subjective age measures in research with elderly people.

Subjective Age and Dementia

OBJECTIVE

Existing evidence indicates that a younger subjective age is a marker of successful aging, including better health and cognition. Building upon this evidence, it is likely that individuals with dementia might feel older. However, subjective evaluation of age might not be affected by dementia because these individuals tend to be anosognosic and report positive health-related quality of life.

METHODS

Data from two cross-sectional samples from France and the United States were used to compare the subjective age ratings of individuals with and without dementia.

RESULTS

Results from both samples revealed that individuals with dementia felt younger than their age but did not differ from the controls, even after controlling for sex, chronological age, education, and self-rated health.

CONCLUSION

The present study suggests that there are no large differences in the subjective experience of age between healthy individuals and those with dementia.

The Importance of Team Health Climate for Health-Related Outcomes of White-Collar Workers

Occupational health researchers and practitioners have mainly focused on the individual and organizational levels, whereas the team level has been largely neglected. In this study, we define team health climate as employees’ shared perceptions of the extent to which their team is concerned, cares, and communicates about health issues. Based on climate, signaling, and social exchange theories, we examined a multilevel model of team health climate and its relationships with five well-established health-related outcomes (i.e., subjective general health, psychosomatic complaints, mental health, work ability, and presenteeism). Results of multilevel analyses of data provided by 6,449 employees in 621 teams of a large organization showed that team health climate is positively related to subjective general health, mental health, and work ability, and negatively related to presenteeism, above and beyond the effects of team size, age, job tenure, job demands, job control, and employees’ individual perceptions of health climate. Moreover, additional analyses showed that a positive team health climate buffered the negative relationship between employee age and work ability. Implications for future research on team health climate and suggestions for occupational health interventions in teams are discussed.

Influence of personality traits in self-evaluative salience, motivational salience and self-consciousness of appearance

Aim

The aim of this study was to understand the possible influence of personality traits on the importance and significance of perception of body image and self-awareness of appearance in individuals.

Method

214 online recruited subjects between the ages of 17 and 64 years answered to a socio-demographic questionnaire, the Portuguese version of the instruments NEO-FFI (NEO-Five Factor Inventory), ASI-R (The Appearance Schemas Inventory – Revised) and DAS-24 (Derriford Appearance Scale – short).

Results

It was found that age, Neuroticism and Agreeableness dimensions significantly influence an individual's investment in body image and self-awareness of appearance. Sexual orientations differed with regard to Self-Evaluative Salience and Self-Consciousness of Appearance.

Conclusion

The performed analysis showed that neuroticism and agreeableness are related to Self-Evaluative Salience and Self-Consciousness of Appearance.

Subjective age and perceived distance-to-death moderate the association between posttraumatic stress symptoms and posttraumatic growth among older adults

OBJECTIVES

Little research has addressed the association between posttraumatic stress (PTS) symptoms and posttraumatic growth (PTG) in the second half of life. This study examined whether subjective age and perceived distance-to-death moderate this association.

METHOD

339 community-dwelling older adults (age range 50-90; M = 65.44, SD = 9.77) were sampled through random dialing to Jewish residents in the south of Israel. Participants completed a phone-questionnaire on PTS symptoms, level of PTG, subjective age, and perceived distance-to-death.

RESULTS

Higher levels of PTS symptoms were both linearly and curvilinearly related to higher PTG. Additionally, subjective age and perceived distance-to-death moderated this association in a linear way, so that the association was strongest in participants who reported younger subjective age and further distance-to-death.

DISCUSSION

The findings emphasize the moderating effect of two time perspectives, one that focuses on time since birth and another that concerns the time that remains before death. These two perspectives affect the association between posttraumatic stress and posttraumatic growth within older individuals.

Stress and Subjective Age: Those With Greater Financial Stress Look Older

Subjective indicators of age add to our understanding of the aging process beyond the role of chronological age. We examined whether financial stress contributes to subjective age as rated by others and the self. The participants ( N = 228), aged 26-75, were from a Boston area satellite of the Midlife in the United States (MIDUS) longitudinal study. Participants reported how old they felt and how old they thought they looked, and observers assessed the participants' age based on photographs (other-look age), at two occasions, an average of 10 years apart. Financial stress was measured at Time 1. Controlling for income, general stress, health, and attractiveness, participants who reported higher levels of financial stress were perceived as older than their actual age to a greater extent and showed larger increases in other-look age over time. We consider the results on accelerated aging of appearance with regard to their implications for interpersonal interactions and in relation to health.

Activities of the elderly and their satisfaction with life

Successful aging (Rowe & Kahn, 1997) is conditioned by aspiration to be active and by the ability to maintain social relations. Activity improves the emotional lives of seniors and is associated with a reduction of some symptoms of aging. Our study verifies if the number of activities (informal and solitary) is associated with quality of life and whether subjective age may be a mediator of this relationship. The 136 seniors above 60 were tested by our authorial scale of activity and the WHOQOL-BRIEF. The results showed that older persons’ higher quality of life levels are related not only to the number of activities undertaken, but also to the frequency that these activities are engaged in. The mediating role of subjective age in relation to one’s activities and quality of life was also indicated, which, concerning general quality of life, turned out to be a cooperative suppression.

The interactive effect of subjective age and subjective distance-to-death on psychological distress of older adults

OBJECTIVES

Subjective age refers to how young or old people experience themselves to be, while subjective distance-to-death reflects how far or close they experience themselves to be from their death. The present study examined whether subjective age and subjective distance-to-death interact in predicting psychological distress.

METHOD

A sample of 1073 community-dwelling older adults at the age range of 50-86 (M = 58.1, SD = 5.3) evaluated their subjective age, subjective distance-to-death, psychological distress, and rated several measures of physical health.

RESULTS

After controlling for background characteristics and physical health indices, perceiving death as far and reporting younger subjective age predicted lower psychological distress. The combination of feeling close to death and older subjective age was related to the highest ratings of psychological distress. Moreover, the effect of subjective distance-to-death on psychological distress was mitigated by younger subjective age.

CONCLUSION

The findings underscore the importance of an integrative view of two time perspectives - one that focuses on time since birth and another that concerns time left till death - to psychological distress of older adults.

How old do you feel? The role of age discrimination and biological aging in subjective age

Subjective age, or how young or old individuals experience themselves to be relative to their chronological age, is a crucial construct in gerontology. Subjective age is a significant predictor of important health outcomes, but little is known about the criteria by which individuals' subjectively evaluate their age. To identify psychosocial and biomedical factors linked to the subjective evaluation of age, this study examined whether perceived age discrimination and markers of biological aging are associated with subjective age. Participants were 4776 adults (M_age = 68) from the 2008 and 2010 waves of the Health and Retirement Study (HRS) who completed measures of subjective age, age discrimination, demographic variables, self-rated health and depression, and had physical health measures, including peak expiratory flow, grip strength, waist circumference, systolic and diastolic blood pressure. Telomere length was available for a subset of participants in the 2008 wave (n = 2214). Regression analysis indicated that perceived age discrimination, lower peak expiratory flow, lower grip strength, and higher waist circumference were associated with an older subjective age, controlling for sociodemographic factors, self-rated health, and depression. In contrast, blood pressure and telomere length were not related to subjective age. These findings are consistent with the hypothesis that how old a person feels depends in part on psychosocial and biomedical factors, including the experiences of ageism and perceptible indices of fitness and biological age.

Subjective age and cognitive functioning: a 10-year prospective study

OBJECTIVES

The present study examines whether subjective age (i.e., how old or young individuals feel) is associated with cognitive functioning and tests potential mediators of this association.

DESIGN

Data from the two waves of measurement of the Midlife in the United States survey were used, with assessments conducted at the first wave in 1994-1995 and at the second wave in 2004-2006.

PARTICIPANTS

A total of 1,352 men and women aged from 50 to 75 years at baseline (M: 59.32; SD: 6.72).

MEASUREMENTS

Subjective age, body mass index (BMI), physical activity, and the covariates sex, age, education, marital status, and disease burden were assessed at baseline to predict episodic memory and executive function measured 10 years later.

RESULTS

Multiple regression analysis revealed that a younger subjective age at baseline was prospectively associated with better episodic memory and executive function. Bootstrap analysis indicated that the association of subjective age with episodic memory and executive function was partially mediated by BMI and frequency of physical activity respectively.

CONCLUSION

Even after accounting for chronological age and other risk factors for cognitive decline, such as disease burden and sedentary lifestyle, the subjective experience of aging predicts cognitive functioning in old age.
