Instructed reappraisal has previously been associated with a challenge-oriented cardiovascular response profile, indexed by greater cardiac output (CO) and lower total peripheral resistance (TPR), in response to a single stress exposure. The present study builds on this research by employing a stress habituation paradigm where participants completed a speech task twice; in which prior to the second task participants heard reappraisal instructions (i.e., view feelings of stress arousal as something that is beneficial) or control instructions. This paradigm allowed us to (a) test if reappraisal aids cardiovascular habituation to recurrent stress, and (b) examine if reappraisal leads to a within-participant change in CO/TPR responding from an uninstructed task to an instructed reappraisal task. Habitual use of reappraisal was assessed using the Emotion Regulation Questionnaire. The analyses report upon 173 young adults (121 women, 52 men). Cardiovascular parameters were measured continuously using the Finometer Pro. All participants demonstrated similar cardiovascular habituation during the second stress exposure (lower SBP, CO, and HR); suggesting that reappraisal did not aid cardiovascular habituation to recurrent stress. Reappraisal instructions did not lead to a challenge-oriented response compared to both the control group and responses to the uninstructed task. This study is the first to examine the relationship between instructed reappraisal and cardiovascular habituation and identifies that habitual use of reappraisal does not interact with reappraisal instructions to influence cardiovascular responses to stress.
指导重评先前与一种以挑战为导向的心血管反应模式相关联，其特征是在单次应激暴露下，心输出量（CO）增加和总外周阻力（TPR）降低。本研究通过采用应激习惯化范式进一步研究，其中参与者两次完成演讲任务；在第二次任务之前，参与者听到重评指导（即，将压力引起的情绪视为有益的事情）或对照指导。这种范式使我们能够：（a）检验重评是否有助于心血管对反复应激的习惯化；（b）检验重评是否导致参与者从无指导的任务到指导的重评任务时，CO/TPR 反应发生个体内变化。习惯性使用重评通过情绪调节问卷进行评估。该分析报告了 173 名年轻成年人（121 名女性，52 名男性）的情况。使用 Finometer Pro 连续测量心血管参数。所有参与者在第二次应激暴露期间表现出类似的心血管习惯化（SBP、CO 和 HR 降低）；这表明重评并没有帮助心血管对反复应激的习惯化。与对照组和无指导任务的反应相比，重评指导并没有导致以挑战为导向的反应。这项研究首次检验了指导重评与心血管习惯化之间的关系，并确定习惯性使用重评不会与重评指导相互作用，从而影响对压力的心血管反应。
