The influence of subjective aging on health and longevity: A meta-analysis of longitudinal data

The goal of this article is to synthesize findings of existing longitudinal studies through a meta-analysis. A systematic search in PsycInfo, Web of Science, Scopus, and Pubmed resulted in 19 longitudinal studies reporting effects of subjective aging on health, health behaviors, and longevity. The authors combine the outcomes reported in these studies using a random effects meta-analysis, assuming that there would be differences in effect sizes across studies. The meta-analysis resulted in an overall significant effect of subjective aging (likelihood ratio = 1.429; 95% confidence interval = 1.273-1.604; p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .001). The analyses revealed heterogeneity, with stronger effects for studies with a shorter period of follow-up, for studies of health versus survival, for studies with younger participants (average age of the studies varies between 57 and 85 years with a median of 63 years), and for studies in welfare systems where state provisions of welfare are minimal. However, effects did not vary either across different operationalizations of subjective aging or by study quality. Subjective aging has a small significant effect on health, health behaviors, and survival. Further theoretical conceptualizations and empirical studies are needed to determine how subjective aging contributes to health and survival.

Examination of Associations Among Three Distinct Subjective Aging Constructs and Their Relevance for Predicting Developmental Correlates

Participants were 819 adults aged 40-98 years from the United States and Germany. Parallel multiple mediation, moderated mediation, and hierarchical regression analyses were used. As hypothesized, AARC mediated the association between the global measures of SA (felt age and ATOA) and the developmental correlates. Specifically, more negative global subjective aging predicted more AARC losses, which predicted poorer health and well-being. Furthermore, this mediation pathway was moderated by chronological age, such that, with increasing age, greater AARC was more strongly related to poorer func...

Zum Erleben von altersbezogenen Veraenderungen im Erwachsenenalter. Eine explorative Studie auf der Grundlage des Konzepts "Awareness of Age-Related Change (AARC)

Der vorliegenden Studie liegt das Konzept "Awareness of Age-Related Change" (AARC; Diehl & Wahl, 2010) und ein entsprechender Fragebogen zu Grunde. Die empirische Grundlage der Studie bildete eine Stichprobe von 265 Personen (69 % Frauen; 40 -87 Jahre). Zunächst wurden in einer Kombination von explorativen und konfirmatorischen Analysen aus ursprünglich 60 generierten Items, die gleichermaßen Gewinne und Verluste in unterschiedlichen Bereichen altersbezogener Veränderungen beinhalteten, ein optimiertes Itemset von 2 x 16 Items identifiziert (Gewinnbasiertes AARC: Cronbachs alpha = .82; Verlustbasiertes AARC: Cronbachs alpha = .87; Interkorrelation: r = -.05; RMSEA = .045). Insgesamt zeigten sich auf dieser Messgrundlage im Wesentlichen die erwarteten Zusammenhänge. So korrelierte vor allem verlustbasiertes AARC deutlich positiv mit Neurotizismus, negativ mit Extraversion und negativ mit Indikatoren erfolgreichen Alterns. Insgesamt bestätigen die Befunde, dass Ä lterwerden vor allem durch ein negativ getöntes Alternsveränderungserleben charakterisiert ist.

Theorists have suggested that researchers should focus on the effects of daily stress and coping rather than focusing exclusively on major life events and chronic stress and have proposed that understanding how adults cope with daily stress is a key aspect of understanding long-term well-being and adaptation in adulthood. After presenting a conceptual model outlining the major components of the daily stress process, the chapter reviews the existing empirical literature on personal risk and resilience factors in the context of daily stress. This research clearly sug-gests that there is no universal generalization that can be made regarding whether chronological age, in and of itself, confers greater vulnerability or resilience onto adults. Instead, we argue that researchers should ask when and under what condi-tions is age associa...
