Personality and psychological traits are known to influence how individuals react to and cope with stress, and thus, have downstream health and aging consequences. However, research considering psychological health traits as individual‐level difference factors moderating the links been racism‐related stress and health for racial and ethnic minorities in the United States is rare. Using intensive daily diaries and a wearable sensor that continuously recorded sympathetic nervous system arousal in a sample of racial and ethnic minority college students (80% African American, first‐generation Black, or African; 20% Latinx), we linked arousal to racism‐related experiences dynamically throughout the day as participants naturally went about their lives. Findings suggest that multiple traits are associated with increased arousal in real time when interpersonal discrimination is perceived, but that only anger and anxiety also predicted increased arousal during moments of rumination and reflection on race‐related inequities. Vicarious discrimination exposure moments were also linked to suppressed arousal in general, but particularly for more anxious individuals. We use a stress appraisal and coping framework to elucidate the ways in which individual psychological differences may inform physiological responses to race‐related stress. The biopsychosocial pathways by which cognitive appraisal and interpersonal race‐related stress contribute to racial health disparities are also discussed.

在自然环境中，特质心理特征是否会调节对种族歧视暴露的同情心唤起？

众所周知，性格和心理特征会影响个人对压力的反应和应对方式，从而对健康和衰老产生下游影响。然而，将心理健康特征视为个体水平差异因素来调节美国少数族裔与种族主义相关压力与健康之间联系的研究很少。我们使用密集的每日日记和可穿戴传感器连续记录少数民族大学生样本（80% 非裔美国人、第一代黑人或非洲人；20% 拉丁裔）的交感神经系统唤醒情况，我们将唤醒与种族主义联系起来。当参与者自然地开始他们的生活时，相关的体验全天动态地进行。研究结果表明，当感知到人际歧视时，多种特征与实时的唤醒程度增加有关，但只有愤怒和焦虑也可以预测在反思和反思种族相​​关不平等时的唤醒程度增加。一般来说，替代歧视暴露时刻也与抑制性兴奋有关，特别是对于更焦虑的人来说。我们使用压力评估和应对框架来阐明个体心理差异如何影响对种族相关压力的生理反应。还讨论了认知评估和人际种族相关压力导致种族健康差异的生物心理社会途径。
