Numerous studies have associated interdependent self-construal (InterSC) with heightened acute salivary cortisol stress responses in collectivist cultures. Hair cortisol concentration (HCC) is an important biomarker of chronic stress and is associated with acute salivary cortisol stress response. However, few studies have explored the association between InterSC and HCC. This study aimed to investigate the role of InterSC in the acute salivary cortisol stress response, HCC, and their associations. Seventy-seven healthy Chinese participants underwent assessments of InterSC, social anxiety, and HCC. The ScanSTRESS paradigm was used to induce an acute stress response and saliva samples were collected. These results replicated earlier findings showing that InterSC was associated with rapid salivary cortisol reactivity and recovery during acute stress. Additionally, InterSC was positively correlated with HCC, and social anxiety mediated this association. Importantly, InterSC moderated the HCC-acute salivary cortisol stress response association. Specifically, high HCC predicted a blunted acute salivary cortisol stress response in participants with low InterSC, including a slow salivary cortisol response during the acute stress reactivity phase and a small overall acute salivary cortisol response. However, this blunting effect was not observed with high InterSC participants, indicating that high InterSC buffered the blunting effect of HCC on the acute salivary cortisol stress response. In conclusion, this study provided new insights into how InterSC is associated with the hypothalamus-pituitary-adrenal axis stress system and revealed the dual-faceted role of InterSC for acute salivary cortisol stress and HCC.
众多研究表明，相互依存的自我构念（InterSC）与集体主义文化中急性唾液皮质醇应激反应升高有关。头发皮质醇浓度（HCC）是慢性应激的重要生物标志物，与急性唾液皮质醇应激反应有关。然而，很少有研究探讨 InterSC 与 HCC 之间的关系。本研究旨在探讨 InterSC 在急性唾液皮质醇应激反应、HCC 及其相关性中的作用。77 名健康的中国参与者接受了 InterSC、社交焦虑和 HCC 的评估。使用 ScanSTRESS 范式诱发急性应激反应，并采集唾液样本。这些结果复制了早期的发现，表明 InterSC 与急性应激期间快速唾液皮质醇反应性和恢复有关。此外，InterSC 与 HCC 呈正相关，社交焦虑介导了这种关联。重要的是，InterSC 调节了 HCC-急性唾液皮质醇应激反应的关联。具体来说，高 HCC 预示着低 InterSC 参与者的急性唾液皮质醇应激反应减弱，包括在急性应激反应阶段唾液皮质醇反应缓慢，以及整体急性唾液皮质醇反应较小。然而，在高 InterSC 参与者中没有观察到这种减弱效应，表明高 InterSC 缓冲了 HCC 对急性唾液皮质醇应激反应的减弱效应。总之，本研究提供了新的见解，说明 InterSC 如何与下丘脑-垂体-肾上腺轴应激系统相关，并揭示了 InterSC 对急性唾液皮质醇应激和 HCC 的双重作用。
