压力和消极的情感状态与日常生活中的皮质醇有关。然而，目前还不清楚什么类型的压力和情感状态产生这些协会，和特质焦虑的影响是未知的。本研究探讨了日常生活中特定任务相关应激源和负性情感状态与唾液皮质醇的关系，探讨了状态负性情感和特质焦虑的中介机制和调节机制。使用手持计算机收集自我报告和时间戳，并使用电子设备监测唾液采样依从性。压力的措施，包括在日常工作中的表现压力和失败的经验;措施的负面影响，包括磨损，紧张，不高兴，生气。使用多级固定场合models.Momentary性能进行了测试，压力下的瞬时表现与较高的瞬时皮质醇措施，白色平均任务失败与较低的每日皮质醇浓度。表现压力与皮质醇的关联在不同的受试者之间存在差异，这种差异可以用特质焦虑来解释，在特质焦虑得分高的参与者中产生了更强的关联。没有证据表明，一个中介的状态negative affect.These结果描述了良好的记录协会的日常压力和影响与唾液皮质醇更精确，这表明，性能压力是一个显着的条件相关的短期变化皮质醇。特质焦虑得分高的受试者处理压力相关信息的方式似乎放大了表现压力与下丘脑-垂体-肾上腺轴反应的关联。(C)2006爱思唯尔有限公司保留所有权利。
Stress and negative affective states are associated with cortisol in everyday life. However, it remains unclear what types of stressors and which affective states yield these associations, and the effect of trait anxiety is unknown. This study investigates the associations of specific task-related stressors and negative affective states in everyday lif e with salivary cortisol, and explores the mediating and moderating rote of state negative affect and trait anxiety, respectively.Salivary cortisol, subjective stress, and state negative affect were measured three times a day on 2 days in 71 participants in everyday life, using a handheld computer to collect self-reports and time stamps and an electronic device to monitor saliva sampling compliance. Stress measures comprised the experience of performance pressure and failure during daily tasks; measures of negative affect comprised worn-out, tense, unhappy, and angry. Effects were tested using multilevel fixed-occasion models.Momentary performance under pressure was related to higher momentary cortisol measures, white mean task failure was related to lower daily cortisol concentrations. The association of performance pressure with cortisol varied between subjects, and this variation was explained by trait anxiety, yielding stronger associations in participants scoring high on trait anxiety. No evidence was found for a mediating rote of state negative affect.These results describe the well-documented associations of everyday stressors and affect with salivary cortisol more precisely, suggesting that performance pressure is a significant condition related to short-term changes in cortisol. Subjects scoring high on trait anxiety seem to process stress-relevant information in a way that amplifies the association of performance pressure with reactions of the hypothalamus-pituitary-adrenal axis.
