Abstract

fetched live from OpenAlex

Current demographics are shifting rapidly and the proportion of older adults in the population is growing. In addition, older adulthood now spans more than 30 years of life (Oeppen & Vaupel, 2002). Old age is likely to be accompanied by increasing presence of age-related challenges along with diminishing opportunities to attain important life goals (Baltes & Smith, 2003; National Advisory Council on Aging, 2006). Such circumstances may trigger increased psychological stress in the short-term and may require long-term adaptations as important life goals become unattainable (Heckhausen, Wrosch, & Schulz, 2010). Two individual difference variables, dispositional optimism and goal disengagement have been found to be adaptive in the management of stressful life circumstances and may allow older adults to effectively negotiate changes in age-related opportunities and challenges (Scheier et al., 2010; Wrosch et al., 2013). \n\tStudy 1 investigated the role of optimism in the regulation of stress across 6 years in a sample of 135 community dwelling older adults. This study examined the relation between dispositional optimism, perceived stress and cortisol by modelling both, with-in person and between-person associations. Within-person results showed that under circumstances when individuals perceived higher than typical stress levels, optimism buffered against increases across most indicators of cortisol (except CAR). Conversely, between-person results showed that among individuals with higher perceived stress, optimism was associated with a lower CAR. Findings showed that optimism facilitated the physiological management of short-term stress by guarding against increases in cortisol in older adulthood. \n\tStudy 2 examined whether the emotional benefits of optimism vary across older adulthood with declining opportunities to overcome stressors. A total of 171 older adults were assessed over a 6 year period to determine how optimism was related to changes in depressive symptoms and perceived stress across older adulthood. Results showed that dispositional optimism protected participants in early phases of older adulthood from exhibiting elevations in depressive symptoms over time, but had reduced benefits among those in advanced old age. The age-related association between optimism and depressive symptoms was most evident during times of stress. These results suggest that the adaptive effects of dispositional optimism become reduced in advanced old age. \n\tStudy 3 explored the age-related associations between goal disengagement capacities, emotional distress, and changes in disease severity across older adulthood. This study examined 131 older adults to determine whether goal disengagement capacities protect older adults particularly in advanced old age against experienced illness by preventing emotional distress. Results indicated that goal disengagement capacities protected against 6-year increases in older adults’ self-reported cold symptoms, this effect was particularly pronounced among those in advanced old age. Changes in depressive symptoms were found to mediate the age-related association between goal disengagement and changes in cold symptoms. These findings suggest that as older adults advance in age, goal disengagement capacities may become increasingly important for protecting emotional well-being and physical health. \n\tOverall, the findings outlined have important implications for research in the areas of personality, aging and health. Mechanisms through which dispositional optimism and goal disengagement facilitate the adaptive management of stress throughout older adulthood are highlighted. This research broadens existing life-span theories of motivation by integrating theories of personality with goal-specific processes and may reveal pathways to successful development in older adulthood. Limitations and future directions are discussed.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
