Abstract

The link between neuroticism and the various indicators of daily cortisol fluctuations is frequently noted to be inconsistent or lacking in strength. The current study aimed to investigate the predictive capacity of both self-assessment and external evaluations of neuroticism, along with their interaction, on multiple indices of diurnal cortisol variations. This research involved the assessment of neuroticism using self-report and external evaluations among 166 working individuals, coupled with the collection of saliva samples over two consecutive workdays. Employing multilevel response surface analysis, our findings indicated that self-reported neuroticism exhibited a stronger association with cortisol indices compared to external evaluations. Additionally, the level of alignment between self-assessment and external ratings of neuroticism specifically impacted the prediction of estimates of daily cortisol production. We discuss the theoretical and practical implications of these results.

昼夜皮质醇测量与自我和他人对神经质的评价明显相关

神经质与皮质醇日波动的各种指标之间的联系经常被指出不一致或缺乏强度。本研究旨在调查神经质的自我评估和外部评价以及它们之间的相互作用对皮质醇昼夜变化的多种指标的预测能力。这项研究使用自我报告和外部评价对 166 名上班族的神经质进行评估，并在连续两个工作日收集唾液样本。通过多层次响应面分析，我们的研究结果表明，与外部评价相比，自我报告的神经质与皮质醇指数的关联度更高。此外，神经质的自我评估和外部评价之间的一致程度特别影响了对每日皮质醇分泌估计值的预测。我们将讨论这些结果的理论和实践意义。

期刊介绍： The International Journal of Psychophysiology is the official journal of the International Organization of Psychophysiology, and provides a respected forum for the publication of high quality original contributions on all aspects of psychophysiology. The journal is interdisciplinary and aims to integrate the neurosciences and behavioral sciences. Empirical, theoretical, and review articles are encouraged in the following areas: • Cerebral psychophysiology: including functional brain mapping and neuroimaging with Event-Related Potentials (ERPs), Positron Emission Tomography (PET), Functional Magnetic Resonance Imaging (fMRI) and Electroencephalographic studies. • Autonomic functions: including bilateral electrodermal activity, pupillometry and blood volume changes. • Cardiovascular Psychophysiology:including studies of blood pressure, cardiac functioning and respiration. • Somatic psychophysiology: including muscle activity, eye movements and eye blinks.
