Holding oral presentations in a university course is perceived as stressful and can increase stress hormone concentrations and state anxiety. In such a naturalistic setting, further attention should be paid to the relationship between psychological and hormonal measures of acute stress, as well as women's intake of hormonal contraceptives as a potential moderating variable. In the present study, 76 healthy students gave saliva samples before and after their oral presentations in a university course as well as on a second, control day in the same course without giving an oral presentation. Anticipatory state anxiety was rated on both days. Cortisol concentrations as well as state anxiety were substantially higher on the presentation relative to the control day. During the oral presentation, an increase in cortisol concentrations was observed, whereas a decrease occurred on the control day. Nearly the same picture emerged for both variables when looking at men, women taking hormonal contraceptives and free-cycling women separately. A positive correlation was found between the change in anticipatory state anxiety in the presentation compared to the control day and cortisol concentrations before and after the oral presentation. Concluding, oral presentations constitute a potent stressor and do not seem to be substantially different between men, free-cycling women and women taking hormonal contraceptives. Future studies may want to explore changes associated with specific menstrual cycle phases and with specific hormonal contraceptives.
在大学课程中进行口头报告被认为是有压力的,并且会增加应激激素浓度和状态焦虑。在这样的自然环境中,应进一步关注急性应激的心理和激素指标之间的关系,以及女性服用激素避孕药作为一个潜在的调节变量。在本研究中,76名健康学生在大学课程的口头报告前后以及在同一课程的第二个对照日(未进行口头报告)采集了唾液样本。在这两天都对预期状态焦虑进行了评分。与对照日相比,报告日的皮质醇浓度和状态焦虑显著更高。在口头报告期间,观察到皮质醇浓度增加,而在对照日则出现下降。分别观察男性、服用激素避孕药的女性和月经周期正常的女性时,这两个变量出现了几乎相同的情况。与对照日相比,报告中预期状态焦虑的变化与口头报告前后的皮质醇浓度之间存在正相关。总之,口头报告是一种强大的应激源,男性、月经周期正常的女性和服用激素避孕药的女性之间似乎没有实质性差异。未来的研究可能想要探索与特定月经周期阶段和特定激素避孕药相关的变化。
