OBJECTIVE This cross-sectional study examines associations between cardiac vagal control and mainstream acculturation by systematically investigating the independent contributions of resting, reactivity, and recovery Respiratory Sinus Arrhythmia (RSA)-physiological factors contributing to adaptive functioning, including social engagement capacity. This study also examines the moderating role of RSA reactivity in associations between perceived ethnic discrimination and mainstream acculturation. METHOD The sample comprised 111 migrants from Maghreb (Morocco, Algeria, and Tunisia) to Montreal, QC, Canada. On average, participants (60 women) were 31 years old and had immigrated 7 years prior to the study. The study design was cross-sectional. We collected both psychophysiological (electrocardiogram) and self-report questionnaire data. RESULTS All three facets of cardiac vagal control are independently associated with mainstream acculturation: Higher mainstream acculturation was associated with higher resting RSA (β = .24), lower RSA reactivity (β = -.27), and higher recovery RSA (β = .26), controlling for several theoretically relevant covariates. Furthermore, lower RSA reactivity to a discrimination-recall task dampened the relation between perceived discrimination and mainstream acculturation (interaction β = -.20). CONCLUSIONS This study replicates and extends prior work linking RSA and mainstream acculturation using a sample of racialized and marginalized migrants. It provides evidence that RSA is related to migrants' adoption of the mainstream culture and may modulate how they handle perceived ethnic discrimination. Thus, this study also provides evidence that RSA is tied to how individuals successfully navigate novel social environments, including novel cultural contexts.

移民中的心脏迷走神经控制:与主流文化适应和种族歧视的关联。



目的 这项横断面研究通过系统地研究休息、反应性和恢复呼吸性窦性心律失常 (RSA) 的独立贡献——有助于适应功能(包括社会参与能力)的生理因素,探讨心脏迷走神经控制与主流文化适应之间的关联。这项研究还探讨了 RSA 反应性在感知种族歧视和主流文化适应之间的调节作用。方法 样本包括 111 名从马格里布(摩洛哥、阿尔及利亚和突尼斯)到加拿大魁北克省蒙特利尔的移民。参与者(60 名女性)平均年龄为 31 岁,在研究前已移民 7 年。研究设计是横断面的。我们收集了心理生理学(心电图)和自我报告问卷数据。结果心脏迷走神经控制的所有三个方面都与主流文化适应独立相关:较高的主流文化适应与较高的静息 RSA (β = .24)、较低的 RSA 反应性 (β = -.27) 和较高的恢复 RSA (β = .24) 相关。 26),控制了几个理论上相关的协变量。此外,RSA 对辨别回忆任务的较低反应性削弱了感知歧视与主流文化适应之间的关系(交互作用 β = -.20)。结论 本研究利用种族化和边缘化移民样本,复制并扩展了之前将 RSA 与主流文化适应联系起来的工作。它提供的证据表明,RSA 与移民接受主流文化有关,并可能调节他们处理种族歧视的方式。 因此,这项研究还提供了证据,证明 RSA 与个人如何成功驾驭新的社会环境(包括新的文化背景)有关。 (PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。
