Thus far, successful aging has been conceptualized and operationalized as a relatively static construct. Investigating daily successful aging provides a dynamic approach highlighting how successful aging can be achieved through everyday actions, giving older adults a stronger sense of control over their lives.
We used 8-day diary data from Midlife in the United States 2's U.S. national sample of older adults (N = 716, Mage[standard deviation, SD] = 68.80[6.45]). Participants reported daily physical symptoms, functioning, and engagement in life (collectively, successful aging indicators), alongside daily stressors and positive events. We also correlated the personal mean and standard deviation of the indicators with 1-time measures of health and well-being.
Intraclass correlation revealed substantial within-person variability in successful aging indicators. These indicators were associated with daily stressors and positive events. One-time health and well-being indicators were positively associated with personal mean levels of successful aging, although their correlations with personal SDs were less consistent.
Intraindividual variations in successful aging as everyday symptoms, functioning, and engagement with life are observable among a national sample of older adults, challenging the static view of successful aging and, instead, emphasizing the need to understand "micro-level" contributors of successful aging.
到目前为止，成功老龄化一直被概念化为一种相对静态的结构并加以实施。研究日常的成功老龄化提供了一种动态方法，突出了如何通过日常行动实现成功老龄化，让老年人对自己的生活有更强的掌控感。
我们使用了来自美国中年研究2的美国全国老年人样本（N = 716，年龄均值[标准差，SD]=68.80[6.45]）的8天日记数据。参与者报告了日常身体症状、功能状况以及生活参与度（统称为成功老龄化指标），同时还报告了日常压力源和积极事件。我们还将这些指标的个人均值和标准差与健康和幸福感的一次性测量结果进行了关联。
组内相关显示成功老龄化指标在个体内部存在很大差异。这些指标与日常压力源和积极事件相关。一次性的健康和幸福感指标与成功老龄化的个人平均水平呈正相关，尽管它们与个人标准差的相关性不太一致。
在全国老年人样本中可以观察到成功老龄化在日常症状、功能状况和生活参与度方面的个体差异，这挑战了成功老龄化的静态观点，相反，强调了理解成功老龄化“微观层面”影响因素的必要性。
