Lower cardiovascular reactivity is a proposed marker of motivational dysregulation and is related to a range of adverse behavioural and health outcomes. Social participation is a form of motivated behaviour and represents the frequency in which an individual engages in social activities. Low social participation has recently been linked to lower cardiovascular responses to acute psychological stress. With recent work emphasizing the importance of assessing adaptation of the cardiovascular response to recurrent stress, the aim of the current study is to build on previous work by examining the relationship between social participation and cardiovascular stress response adaptation. This study utilised data from the Pittsburgh Cold Study 3 (PCS 3). Two hundred and thirteen participants (M = 30.13; SD = 10.85) completed a social participation measure and had their systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) monitored across two separate standardized stress testing sessions. The testing sessions consisted of a 20-minute baseline and a 15-minute stress task. Results indicated that higher levels of social participation were associated with greater blood pressure habituation to recurrent stress, extending previous work identifying that social participation was associated with higher cardiovascular responses to stress. The present study identifies that those reporting greater levels of social participation may show enhanced stress tolerance when exposed to recurrent stress.
心血管反应较低被认为是动机调节障碍的一个标志物，与一系列不良行为和健康结果有关。社会参与是一种有动机的行为，代表个体参与社会活动的频率。最近有研究表明，社会参与度低与急性心理应激时心血管反应降低有关。由于最近的研究强调了评估心血管对反复应激反应适应性的重要性，本研究旨在在前人的基础上进一步探讨社会参与与心血管应激反应适应性之间的关系。本研究利用了匹兹堡冷应激研究 3（PCS 3）的数据。213 名参与者（M=30.13；SD=10.85）完成了一项社会参与度的测量，他们的收缩压（SBP）、舒张压（DBP）和心率（HR）在两次独立的标准化应激测试中进行了监测。测试包括 20 分钟的基础期和 15 分钟的应激任务。结果表明，较高的社会参与度与血压对反复应激的适应性增强有关，这一结果扩展了先前的研究，即社会参与与对压力的更高心血管反应有关。本研究表明，报告有较高社会参与度的个体在反复暴露于应激时可能表现出更强的应激耐受力。
