对过去、现在和未来事件的看法可能与应激病理生理学有关。我们评估了接受特里尔社会压力测试 (TSST) 的健康成年人（N = 61，年龄 = 18-35，M = 22.9，SD = 4.1）的时间视角 (TP) 是否与皮质醇动态相关。 TP 根据两种情况进行测量：适应不良的平衡 TP 偏差 (DBTP) 和适应性的负 TP 偏差 (DNTP)。使用相对于地面的曲线下面积 (AUCg) 和增加 (AUCi) 来分析八个唾液皮质醇样本。统计分析涉及控制抑郁症状的部分相关性。两性的结果表明，较高的 DBTP 分数与较低的皮质醇 AUCg 分数相关，而较高的 DNTP 分数与较高的皮质醇 AUCg 分数相关。这些新发现表明，适应不良的 TP 谱会影响皮质醇增多症，而适应性 TP 谱会影响皮质醇增多症。因此，TP 分布可能会影响以皮质醇浓度改变为特征的状况。
Perceptions of past, present, and future events may be related to stress pathophysiology. We assessed whether Time Perspective (TP) is associated with cortisol dynamics among healthy adults (N = 61, Ages = 18–35, M = 22.9, SD = 4.1) exposed to the Trier Social Stress Test (TSST). TP was measured according to two profiles: maladaptive Deviation from Balanced TP (DBTP) and adaptive Deviation from Negative TP (DNTP). Eight salivary cortisol samples were analyzed using area under the curve with respect to ground (AUCg) and to increase (AUCi). Statistic analyses involved partial correlations controlling for depressive symptoms. Results for both sexes showed that higher DBTP scores were associated with lower cortisol AUCg scores, while higher DNTP scores were associated with higher cortisol AUCg scores. These novel findings suggest that maladaptive TP profiles influence hypocortisolism, whereas adaptive TP profiles influence hypercortisolism. Thus, TP profiles may impact conditions characterized by altered cortisol concentrations.
