Change in attitudes toward aging: Cognitive complaints matter more than objective performance.

Abstract

Converging longitudinal research suggests that more negative views on aging predict accelerated cognitive decline. Although conceptually suggested, reciprocal relationships between cognitive functioning and attitudes toward aging have remained less clear empirically. We used the 20-year data from the Interdisciplinary Longitudinal Study of Adult Development (ILSE) to better understand such potential bidirectionality. Drawing on 1,002 baseline participants from 2 age groups, a midlife (Mage = 43.7 at baseline) and an old age group (Mage = 62.5 at baseline), we examined longitudinal trajectories between attitude toward own aging, performance-based cognitive measures, and subjective cognitive complaints. Findings from multigroup latent growth curve modeling replicated previous findings that attitude toward own aging predicts cognitive change over 20 years in old age with 2 important specifications: We show that this effect (a) does not apply to midlife and (b) disappears in old age after controlling for depression over time. Further, as expected, cognitive complaints but not cognitive performance were related to change in attitude toward own aging in midlife and old age. Results suggest that differentiating between objective cognitive functioning and subjective cognitive complaints is important when investigating relations between cognitive functioning and attitude toward own aging in different age groups.
