Self-Perceptions of Aging and Control of Life in Late Adulthood: Between-Person and Within-Person Associations.

This study aimed to examine the longitudinal relationship between two central concepts in aging research-self-perceptions of aging (SPA) and perceived control of life (COL). The data came from three measurement points over a 9-year period in the Health and Retirement Study (HRS). A random intercepts cross-lagged panel model (RI-CLPM) was estimated. The covariations between SPA and COL across 9 years were evident at both the between-person level and the within-person within-time level. The results revealed a reciprocal relationship between SPA and COL: Higher than usual negative SPA predicted within-person decreases in COL 4 years later, and lower than usual COL predicted future within-person increases in negative SPA. Furthermore, SPA were found to have a somewhat larger effect on COL than the corresponding influence of COL on SPA. This study enriches the stereotype embodiment theory and the practice by documenting a reciprocal interrelationship between SPA and COL.
