The quality and quantity of one's relationships have been reliably linked to morbidity and mortality. More recently, studies have focused on links between relationships and cardiovascular reactivity as a physiological mechanism via the stress-buffering hypothesis. However, not all social relationships are consistently positive which points to the importance of a more comprehensive examination of relationship that includes negative qualities. In this study, we manipulated relationship positivity and negativity with an experimenter and examined its influence on cardiovascular reactivity. Results revealed that relationship positivity was associated with lower systolic blood pressure (SBP) reactivity for men and women. Relationship negativity, on the other hand, was related to less of an increase in diastolic blood pressure (DBP) reactivity in men. Internal analyses showed that perceptions of positivity and negativity interacted such that high positivity/high negativity perceptions (ambivalence) were related to the highest SBP reactivity. Results of this study suggest that the quality of one's relationships is an important moderator of cardiovascular reactivity during stress.
一个人社交关系的质量和数量已被可靠地证明与发病率和死亡率有关。最近，研究聚焦于社交关系与心血管反应性之间的联系，将其作为通过压力缓冲假说的一种生理机制。然而，并非所有的社会关系都始终是积极的，这表明更全面地审视包括消极特质在内的社交关系具有重要意义。在本研究中，我们由一名实验者操控社交关系的积极和消极程度，并考察其对心血管反应性的影响。结果显示，社交关系的积极程度与男性和女性较低的收缩压（SBP）反应性相关。另一方面，社交关系的消极程度与男性舒张压（DBP）反应性增加较少有关。内部分析表明，积极和消极的认知相互作用，以至于高积极/高消极认知（矛盾情绪）与最高的收缩压反应性相关。本研究结果表明，一个人社交关系的质量是压力期间心血管反应性的重要调节因素。
