Abstract

The cortisol awakening response (CAR) has been hypothesized to prepare the body for anticipated demands of the upcoming day. This pilot study investigates the influence of anticipated stress on the upcoming day on the CAR, using an intensive longitudinal design with ecological momentary assessments. Over a 30-day period, three healthy participants collected saliva samples each morning at three time points after awakening to measure cortisol levels and completed a questionnaire each evening on the anticipated stress for the following day. Additionally, they wore a smart headband to objectively determine the time point of awakening. There was high variability in the CAR magnitude within participants over time. A multi-level model was estimated to investigate the influence of anticipated stress on the CAR. Results indicated that anticipated stress is predictive of the CAR on the following morning, with higher anticipated stress being associated with increased cortisol levels at the post-awakening time points. These findings underscore the role of stress anticipation in modulating the CAR and highlight the importance of considering within-person variation and temporally lagged effects in biopsychological research.

预期压力可预测皮质醇觉醒反应：强化纵向试验研究。

皮质醇唤醒反应（CAR）被认为是让身体为即将到来的一天的预期需求做好准备。这项试验性研究采用生态瞬间评估的密集纵向设计，调查了未来一天的预期压力对皮质醇觉醒反应的影响。在为期 30 天的时间里，三名健康的参与者每天早上在起床后的三个时间点采集唾液样本以测量皮质醇水平，并在每天晚上填写一份关于第二天预期压力的问卷。此外，他们还佩戴了一个智能头带，以客观地确定觉醒的时间点。随着时间的推移，参与者体内的 CAR 值变化很大。为研究预期压力对 CAR 的影响，我们估算了一个多层次模型。结果表明，预期压力可预测第二天早上的 CAR，预期压力越大，觉醒后时间点的皮质醇水平越高。这些发现强调了压力预期在调节CAR中的作用，并突出了在心理生物学研究中考虑人内差异和时滞效应的重要性。

期刊介绍： Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
