Subjective age, that is the age people feel in relation to their chronological age, can vary on a day-to-day and even momentary basis. Previous long-term and daily-diary studies have shown that elevated stress covaries with older subjective age. However, it is an open question whether such links can also be observed at the momentary level within a given day and go beyond self-reports of stress. Moving ahead, we investigated how two indicators of stress (self-reported: perceived stress; physiological: salivary cortisol) are associated with the age people feel on a momentary basis. We examined data from 118 older (Mage = 66.67 years) and 36 very old adults (Mage = 85.92 years) who reported their momentary subjective age and perceived stress and also provided saliva samples up to seven times a day over seven consecutive days. Dynamic structural equation models showed that both higher momentary perceived stress and higher cortisol levels preceding the measurement predicted an older momentary subjective age. In contrast, subjective age at the previous measurement did not predict subsequent stress. These effects were moderated by participant age group and grip strength, albeit not consistently. Our results corroborate and extend earlier findings that both self-reported and physiological stress are important explanatory variables for people’s subjective age variation even on relatively short time scales, and shed light on differential time-ordered dynamics between stress and subjective age in daily life. Findings also inform theoretical models of subjective age that highlight the importance of contextual, momentary influences on how old people feel and help better understand how biological and psychological processes are intertwined in later life.

“I Felt so Old This Morning.” Short-Term Variations in Subjective Age and the Role of Trait Subjective Age: Evidence from the ILSE/EMIL Ecological Momentary Assessment Data

Subjective age, how old people feel compared to their chronological age, is a central indicator of age identity and highly predictive for developmental outcomes. While mostly used as a trait-like concept in previous research, recent studies employing experimental designs and daily assessments suggest that subjective age can vary after experimental manipulations or between days. However, less is known about whether subjective age varies over even shorter time frames such as within moments on a given day, how such short-term variability differs by age and its association with trait subjective age. We examined these questions with data obtained from 123 young–old (Mage = 67.19 years) and 47 old–old adults (Mage = 86.59 years) who reported their momentary subjective age six times a day over 7 consecutive days as they were going about their everyday lives. Participants felt younger on a large majority of occasions, and 25% of the total variability in subjective age could be attributed to within-person variation. Within-person variability in subjective age amounted to an average of about 3 years from one moment to the next and did not differ between age groups. However, those with younger trait subjective ages exhibited larger moment-to-moment variation. Our findings extend the literature on subjective age by showing that how old people feel can vary on a momentary basis and that state and trait components of subjective age are related. Further research should investigate the contextual predictors of variability in subjective age and the links between trait and state concepts and developmental outcomes. [less ▲]

The effects of age stereotypes on physical and mental health are mediated by self-perceptions of aging

Examining the Interplay of Generalized and Personal Views on Aging on Physical and Mental Health Across 2.5 Years

It remains unknown how distinct types of views on aging (VoA) are related to one another, and to aging outcomes. We used a latent-variable structural equation model to test the hypothesis that generalized views on aging (assessed as Age Stereotypes (AS)) would influence personal views on aging (assessed as Self-Perceptions of Aging (SPA)), which in-turn would influence later physical and mental health. Data came from a longitudinal survey on VoA (N= 537, MageT1 = 64.13, age rangeT1 = 40-98). As expected, SPA mediated the effect of AS on physical (loss-SPA: β = .23, p< .001; gain-SPA: β = .06, p< .001; R2 = .62) and mental health (loss-SPA: β = .13, p< .001; gain-SPA: β = .03, p< .01, ; R2 = .31). Congruent with theoretical assumptions, our findings provide empirical support for a directional pathway by which generalized views on aging affect health outcomes via personal views of aging.

Big Five personality traits are assumed to be linked with attitudes toward own aging. Since both constructs have central importance for the aging process, it is surprising that to our knowledge no study so far comprehensively addressed their mutual connection over time. We used data from the ILSE study, a longitudinal study capturing personality and attitudes toward own aging at four measurement occasions, spanning 20 years and including two participant cohorts in midlife (n = 501; born 1950–52) and later life (n = 500; born 1930–32). Dual latent change score models showed that personality was longitudinally related to change in attitudes toward own aging: Lower Neuroticism, higher Conscientiousness, and higher Openness predicted more positive attitudes, whereas the direction of the effect for Extraversion varied by time. Furthermore, the role of personality seems to be confined to certain sensitive periods in midlife and early old age. Contrary to our expectations, attitudes toward own aging had only marginal longitudinal impact on the Big Five. Our results shed light on the developmental co-dynamics of personality and subjective perceptions of aging across the second half of the lifespan. [less ▲]

How do views on aging affect health outcomes in adulthood and late life? Explanations for an established connection

Personal views on aging, such as age stereotypes and subjective aging, can affect various health outcomes in later life. For the past 20 years or so, a large body of experimental and longitudinal work has provided ample evidence for this connection. Thus, it seems timely to better understand the pathways of this linkage. The majority of existing studies has either focused on age stereotypes or subjective aging. This theoretical paper provides a systematic comparison of major theoretical approaches that offer explanations through which different views on aging may affect health. After a short review of findings on the short- and long-term effects of different views on aging, we describe theoretical approaches that provide explanations of underlying mechanisms for the effect of both uni- and multidimensional views on aging on health outcomes. We compare the specific characteristics of these approaches, provide a heuristic framework and outline recommendations for future research routes. A better understanding of the impact of different views on aging on health outcomes is not only relevant for basic research in life-span developmental psychology, geropsychology and health psychology, it has also implications for intervention research and public health practices.
