Results suggest that a better integration of research on subjective aging with clinically relevant developmental outcomes is a promising future pathway.

Recent evidence suggests that the longitudinal association between subjective aging experiences, that is, the way people perceive and evaluate their aging process, and well-being-related developmental outcomes depends on individual differences. We investigated the moderating role of two processing strategies, that is, mindfulness and negative repetitive thought (RT), for the association between subjective aging experiences and depressive symptoms in middle and old adulthood. Analyses were based on two measurements covering a 4.5-year interval (Time 1: 2012, N = 423; age range = 40-98 years; Time 2: 2017, N = 299; age range = 44-92 years). Subjective aging experiences were operationalized as awareness of age-related gains and losses. Data were analyzed by means of a latent change score model based on a structural equation modeling approach. Mindfulness buffered the harmful effect of high levels of awareness of age-related losses on change in depressive symptoms. Conversely, negative RT exacerbated the detrimental effect of high levels of awareness of age-related losses and low levels of awareness of age-related gains on change in depressive symptoms. With regard to the interplay between awareness of age-related gains and mindfulness, effects were less robust, although the direction of findings was consistent with theoretical considerations. Effects were comparable across middle-aged and older adults. Subjective aging experiences are not operating in isolation, but always need to be considered in the context of the way individuals are cognitively dealing with them. (PsycINFO Database Record

Abstract. 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 emerged 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.
