Studies have demonstrated the importance of optimism in predicting perceived general health. However, the handful of studies focusing on cardiovascular biomarkers show inconsistent effects. Additionally, no study examined whether spousal levels of optimism and pessimism affect an individual’s biological markers of cardiovascular health. Thus, our objectives were to examine whether partners’ optimism and pessimism affect individual biological markers, differentiating between between‐dyad associations and within‐dyad predictive processes.

年长夫妇的乐观，悲观和健康生物标志物。

研究表明，乐观在预测感知的总体健康方面非常重要。但是，针对心血管生物标志物的少数研究显示出不一致的效果。此外，没有研究检查配偶的乐观和悲观程度是否会影响个人心血管健康的生物学指标。因此，我们的目标是检验伴侣的乐观和悲观情绪是否会影响个体的生物标志物，从而区分二联体之间的关联和二联体内部的预测过程。
