Subjective views of aging in very old age: Predictors of 2-year change in gains and losses.

This study examined trajectories of awareness of age-related change (AARC; Diehl & Wahl, 2010) across 2 years in a large representative sample of very old adults. We also examined the predictive role of health, functional status, cognitive functioning, and engagement with life for AARC change. The initial sample comprised 1,863 individuals aged 80 years or older. Of the 1,612 individuals recontacted 2 years later, 912 took part in the follow-up. Measures included the AARC-Short Form, assessing perceived AARC Gains and AARC Losses. Measures of multimorbidity and functional health, a cognitive screening test, and indicators of engagement with life (e.g., leisure activity) were examined as predictors of AARC change, using semi-cross-lagged fixed effects modeling. Higher overall levels of AARC Gains were observed compared to AARC Losses for all but respondents aged 90 years or older. Intra-individual levels of AARC Gains decreased significantly over the 2-year period, whereas a significant increase was found for AARC Losses. AARC Losses across time were predicted by loss of instrumental activities of daily living (IADL) independence, but not by change in multimorbidity, cognitive performance, or engagement with life. One indicator of engagement with life, reduced leisure activity, predicted smaller AARC Gains at wave 2. These results were robust in models controlling for potential reverse causation. These findings suggest that a significant increase in perceived AARC Losses appears to be an inherent characteristic of very old age. Very old age may be a stage in life in which changes in multimorbidity and cognitive performance no longer impact individuals' views on aging.
