动态评估下丘脑-垂体-肾上腺轴对急性自然应激的反应提供了具有高生态效度的应激调节证据。唾液皮质醇取样是这一领域的标准技术。在21名健康的学生教师中，我们评估了示范课的皮质醇反应。在对照日，在类似的时间重复采样。此外，在两天内评估皮质醇唤醒反应（CAR）。参与者还暴露在一个实验室压力源，特里尔社会压力测试，并评估他们的个人慢性工作压力水平。在压力前-压力后评估中，皮质醇水平在课后下降。然而，与对照组相比，应激后皮质醇水平显著升高。此外，当使用对照日作为参考基线时，特里尔社会压力测试产生了更高的皮质醇反应。仅在对照日观察到CAR和慢性应激测量之间的关联。皮质醇对自然压力和实验室压力的反应之间没有显著的关联。我们的结果表明，对照日可能是一个重要的补充，在实验室，特别是在动态应力研究。此外，慢性应激测量和CAR之间的关联可能被急性应激暴露所掩盖。最后，对实验室压力源的反应似乎并不反映自然的压力反应。版权所有©2012 John Wiley & Sons， Ltd。
Ambulatory assessments of hypothalamus–pituitary–adrenal axis responses to acute natural stressors yield evidence on stress regulation with high ecological validity. Sampling of salivary cortisol is a standard technique in this field.In 21 healthy student teachers, we assessed cortisol responses to a demonstration lesson. On a control day, sampling was repeated at analogous times. Additionally, the cortisol awakening response (CAR) was assessed on both days. Participants were also exposed to a laboratory stressor, the Trier Social Stress Test, and rated their individual levels of chronic work stress.In pre‐to‐post‐stress assessment, cortisol levels declined after the lesson. However, post‐stress cortisol levels were significantly higher compared with those on the control day. Also, the Trier Social Stress Test yielded higher cortisol responses when using the control day as reference baseline. Associations between the CAR and chronic stress measures were observed solely on the control day. There were no significant associations between cortisol responses to the natural and laboratory stressors.Our results indicate that a control day might be an important complement in laboratory but especially in ambulatory stress research. Furthermore, associations between chronic stress measures and the CAR might be obscured by acute stress exposure. Finally, responses to the laboratory stressor do not seem to mirror natural stress responses. Copyright © 2012 John Wiley & Sons, Ltd.
