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.
本研究旨在探讨衰老研究中两个核心概念——自我年龄认知（SPA）和生活控制感（COL）之间的纵向关系。数据来自健康与退休研究（HRS）中 9 年的三个测量点。采用随机截距交叉滞后面板模型（RI-CLPM）进行估计。在个体间和个体内随时间变化的水平上，SPA 和 COL 之间的相互关系在 9 年内都很明显。研究结果揭示了 SPA 和 COL 之间的互惠关系：高于平均水平的负面 SPA 预示着 4 年后个体内 COL 的下降，而低于平均水平的 COL 预示着未来个体内负面 SPA 的增加。此外，SPA 对 COL 的影响比 COL 对 SPA 的相应影响略大。本研究通过记录 SPA 和 COL 之间的互惠关系，丰富了刻板印象体现理论和实践。
