Twenty-three persons participated in a study examining the relationship between daily stressors and daily fluctuations in cortisol. For 21 days, the participants completed the Assessment of Daily Experience scale, which yielded frequency and intensity stress scores and gave an indication of the subjects' perceptions of their control over the daily stressors. Nightly urines were collected and assayed for cortisol. The prospective design of the research allowed the authors to examine individual differences in cortisol over time as well as the often-studied pooled differences. Results from pooled and individual data showed that the intensity of the worst daily stressor was a significant but modest predictor of daily cortisol. The authors concluded that the relationship between cortisol and psychological events for pooled data is small because of the wide variability in individual responses.
23人参与了一项研究，该研究旨在探究日常应激源与皮质醇每日波动之间的关系。在21天的时间里，参与者完成了《日常经历评估量表》，该量表得出了应激频率和强度得分，并表明了受试者对自身应对日常应激源的控制感。每晚收集尿液并检测其中的皮质醇。该研究的前瞻性设计使作者能够考察皮质醇随时间的个体差异以及经常被研究的总体差异。汇总数据和个体数据的结果均表明，每日最严重应激源的强度是每日皮质醇水平的一个显著但较为适度的预测指标。作者得出结论，由于个体反应差异很大，汇总数据中皮质醇与心理事件之间的关系较小。
