Beliefs about aging are grounded in social experience. This study considered the extent to which married older adults' shared beliefs about aging and markers of aging maintain a concurrent and enduring association with their partners' beliefs about and markers of aging. Data from the 2010/2012 and 2014/2016 waves of the Health and Retirement Study provided measures of husbands' and wives' (3,779 couples) positive and negative beliefs about aging and internal (Cystatin C) and external (grip strength) markers of aging at 2 time points. Latent dyadic models parsed beliefs and markers into partners' individual and shared variances, which were connected both cross-sectionally and longitudinally. Longitudinal analysis showed that the cross-sectional associations between shared beliefs and markers of aging were stable over 4 years. Partners' shared beliefs and markers of aging were found to have enduring associations with each other over time. The enduring association between grip strength and future negative beliefs remained significant after accounting for partner selection and similarity in health. Model comparisons across marriage duration and emotional closeness showed partners' beliefs to be more similar in marriages that were either long established or emotionally close. In all groups, shared beliefs and markers of aging were associated with each other over time. The association between positive beliefs and future grip strength was stronger in long-established than in recent marriages. In summary, this study provides evidence that, within older couples, beliefs about aging are shaped in part through experiences of aging together.

已婚伴侣的共同信念和衰老标志之间的并发和持久关联。

关于衰老的信念基于社会经验。这项研究考虑了已婚老年人对衰老和衰老标志的共同信念在多大程度上与其伴侣对衰老的信念和衰老标志保持同步和持久的关联。来自 2010/2012 和 2014/2016 年健康与退休研究浪潮的数据提供了丈夫和妻子（3,779 对夫妇）对衰老以及内部（胱抑素 C）和外部（握力）衰老标志的正面和负面信念的测量在 2 个时间点。潜在的二元模型将信念和标记解析为合作伙伴的个体差异和共享差异，这些差异在横截面和纵向上都有关联。纵向分析表明，共同信念和衰老标志之间的横断面关联在 4 年内保持稳定。随着时间的推移，合作伙伴的共同信念和衰老标志被发现彼此之间具有持久的关联。在考虑到伴侣选择和健康相似性之后，握力与未来负面信念之间的持久关联仍然很重要。对婚姻持续时间和情感亲密程度的模型比较表明，伴侣的信念在长期建立或情感亲密的婚姻中更加相似。在所有群体中，随着时间的推移，共同的信念和衰老标志相互关联。在长期建立的婚姻中，积极信念与未来握力之间的关联比在最近的婚姻中更强。总之，这项研究提供的证据表明，在老年夫妇中，关于衰老的信念部分是通过共同衰老的经历形成的。
