The objective of this study was to examine the link between ethnic-racial identity (ERI) components (exploration, resolution, and affirmation) and youths' diurnal cortisol slopes.
A sample of 103 U.S.-Mexican adolescents (M = 15.29 years) living in the Southwest participated in an in-home interview and 3-day salivary sampling protocol.
ERI affirmation, but not exploration or resolution, was related to steeper diurnal slopes (greater declines in cortisol from waking to bedtime) after controlling for adolescents' life stressors, acculturation level, ethnic-racial discrimination, and daily behaviors (i.e., caffeine use, hours of exercise, hours of sleep, and medication level).
This study provides initial evidence of the physiological benefits of ERI affirmation. Given that steeper diurnal slopes are thought of as an indicator of positive health, our findings point to the importance of examining cultural processes in the well-being of ethnic-racial minority youth.
本研究旨在探讨族裔认同（ERI）成分（探索、解决和肯定）与青少年日间皮质醇斜率之间的联系。
本研究选取了 103 名居住在美国西南部的美国-墨西哥青少年（M=15.29 岁）作为研究对象，他们参与了一项家庭访谈和为期 3 天的唾液采样方案。
在控制青少年生活压力、文化适应水平、族裔歧视和日常行为（即咖啡因使用、运动时间、睡眠时间和药物水平）后，ERI 肯定与日间斜率（皮质醇从醒来到睡前的下降幅度更大）呈正相关，但探索或解决与日间斜率无显著相关。
本研究初步证明了 ERI 肯定对生理健康的益处。鉴于日间斜率较大被认为是健康的一个指标，我们的研究结果表明，在少数族裔青年的幸福感研究中，检验文化过程的重要性。
