Cultural mismatch theory suggests that a poor fit between the cultural values endorsed by individuals and the institutions to which they belong results in emotional distress and activation of physiological stress processes, particularly for underrepresented groups. To test a novel paradigm for reducing perceptions of this cultural mismatch, the current experiment evaluated whether reminding first-year Latino university students (N = 84; Mage = 18.56; SD = 0.35; 63.1% female; 85.7% Mexican descent; 65.5% first-generation college students) about institutional support for cultural diversity and inclusion would reduce neuroendocrine and affective responses to psychosocial stress. Prior to completing a modified version of the Trier Social Stress Test, participants were randomly assigned to view either a video conveying university commitment to cultural diversity and inclusion (n = 45) or a control video (n = 39) depicting a campus tour. Five saliva samples assayed for cortisol and corresponding negative affect measures were collected to assess stress reactivity and recovery patterns (pre-task baseline, post-task +30 min, +45 min, +60 min, +75 min). Repeated measures data were analyzed using bilinear spline growth models. Viewing the culture video (compared to control) significantly reduced cortisol reactivity to the TSST and post-task negative affect levels, specifically for students endorsing higher Latino cultural values (e.g., familism, respect). Post-task cortisol levels were also reduced for students endorsing higher U.S. mainstream cultural values (e.g., self-reliance, competition). Results provide novel evidence for cultural diversity in stress responsivity and individual variation in approaches to reduce perceived cultural mismatch.

减少文化上的不匹配：文化多样性和包容性提示后，拉丁美洲学生的神经内分泌和情感压力反应。

文化失配理论表明，个人认可的文化价值观与其所属机构之间的不恰当融合会导致情绪困扰和生理压力过程的激活，尤其是对于代表性不足的群体而言。为了测试一种新颖的范式来减少对这种文化不匹配的认知，当前的实验评估了是否提醒拉丁裔大一学生（N = 84； Mage = 18.56； SD = 0.35； 63.1％的女性； 85.7％的墨西哥血统； 65.5％的女性）对文化多样性和包容性提供机构支持的三代大学生将减少神经内分泌和对心理压力的情感反应。在完成Trier社会压力测试的修改版本之前，随机分配参与者观看视频，这些视频传达了大学对文化多样性和包容性的承诺（n = 45）或描述校园之旅的控制视频（n = 39）。收集了五份唾液样品，分析皮质醇含量和相应的负面影响，以评估压力反应性和恢复模式（任务前基线，任务后+30分钟，+ 45分钟，+ 60分钟，+ 75分钟）。使用双线性样条增长模型分析重复测量的数据。观看文化视频（与对照视频相比）显着降低了皮质醇对TSST的反应性和任务后的负面影响水平，特别是对于那些认可较高拉丁裔文化价值观（例如，家族主义，尊重）的学生。支持美国主流文化价值观（例如，自力更生，竞争）的学生的任务后皮质醇水平也降低了。
