Negative interpersonal interactions are associated with acute increases in ambulatory blood pressure (ABP). Yet, the mechanisms underlying this relationship are unclear.
This study tested whether negative interpersonal interactions predict higher ABP both in the moment and during subsequent observations, and whether increases in negative mood mediate these relations. These associations were tested among Black and Hispanic urban adults who may be at higher risk for negative interpersonal interactions as a function of discrimination. Race/ethnicity and lifetime discrimination were tested as moderators.
Using a 24-hr ecological momentary assessment (EMA) design, 565 Black and Hispanic participants (aged 23-65, M = 39.06, SD = 9.35; 51.68% men) had their ABP assessed every 20 min during daytime accompanied by an assessment of negative interpersonal interactions and mood. This produced 12,171 paired assessments of ABP and self-reports of participants' interpersonal interactions, including how much the interaction made them feel left out, harassed, and treated unfairly, as well as how angry, nervous, and sad they felt.
Multilevel models revealed that more intense negative interpersonal interactions predicted higher momentary ABP. Mediation analyses revealed that increased negative mood explained the relationship between negative interpersonal interactions and ABP in concurrent and lagged analyses. Discrimination was associated with more negative interpersonal interactions, but neither race/ethnicity nor lifetime discrimination moderated findings.
Results provide a clearer understanding of the psychobiological mechanisms through which interpersonal interactions influence cardiovascular health and may contribute to health disparities. Implications include the potential for just-in-time interventions to provide mood restoring resources after negative interactions.
负面的人际互动与动态血压（ABP）的急性升高有关。然而，这种关系的机制尚不清楚。
本研究旨在测试负面人际互动是否会在当下和随后的观察中预测更高的 ABP，以及负面情绪的增加是否会介导这些关系。这些关联是在可能因歧视而面临更高负面人际互动风险的黑人和西班牙裔城市成年人中进行测试的。种族/民族和终身歧视被测试为调节因素。
使用 24 小时生态瞬时评估（EMA）设计，565 名黑人和西班牙裔参与者（年龄 23-65 岁，M = 39.06，SD = 9.35；51.68%为男性）在白天每 20 分钟评估一次 ABP，并评估负面人际互动和情绪。这产生了 12,171 对参与者的 ABP 和自我报告的人际互动评估，包括互动让他们感到被排斥、被骚扰和受到不公平对待的程度，以及他们感到愤怒、紧张和悲伤的程度。
多层次模型显示，更强烈的负面人际互动预测了更高的即时 ABP。中介分析显示，负面情绪的增加解释了负面人际互动与 ABP 在同期和滞后分析中的关系。歧视与更多的负面人际互动有关，但种族/民族和终身歧视都没有调节这些发现。
研究结果更清楚地了解了人际互动影响心血管健康的心理生物学机制，并可能导致健康差距。这包括在负面互动后提供情绪恢复资源的即时干预的潜力。
