在一个包含52名青少年的社区样本中，我们利用多水平生长曲线模型来检验在自然环境下，瞬时情绪状态的个人变化和特质情绪功能的个体差异是否与青少年皮质醇水平有关。在两个典型的工作日，研究人员每天测量唾液皮质醇水平7次，并结合青少年情绪状态的日记报告。获得了特质情绪功能（抑郁、焦虑和愤怒）的问卷报告，以及人口统计、发展和健康控制变量的报告。在考虑了一天中的时间和一系列控制变量的影响后，人体内消极情绪（担心/压力和愤怒/沮丧）的增加与人体内皮质醇的增加显著相关。在检查特质情绪功能时，抑郁症状水平较高的青少年的基础皮质醇水平略低，而特质愤怒水平较高的青少年对觉醒的皮质醇反应明显更强。研究发现了几种发育效应——处于较高青春期发育阶段的青少年，其白天的基础皮质醇曲线更高，日下降幅度更大，皮质醇觉醒反应更少，皮质醇对焦虑/压力的反应随着年龄的增长而增加。青少年独处时的皮质醇水平也比与其他人在一起时高，这种影响随着年龄的增长而显著下降。青少年独处时的皮质醇水平也比与其他人在一起时高，这种影响随着年龄的增长而显著下降。结果表明，青少年的日常情绪体验与皮质醇水平之间存在持续的交易，青少年皮质醇活动受年龄/青春期阶段和特质情绪功能的影响。(c) 2006 Elsevier Ltd.版权所有。
In a community sample of 52 adolescents, multilevel growth curve modeling was utilized to examine whether within-person changes in momentary mood states, and individual differences in trait emotional functioning, were related to adolescent cortisol levels in naturalistic settings. Salivary cortisol levels were measured seven times a day on two typical weekdays in conjunction with diary reports of adolescent mood states. Questionnaire reports of trait emotional functioning (depression, anxiety, and anger) were obtained, as were reports of demographic, developmental, and health control variables. After accounting for the effects of time of day and a wide range of control variables, within-person increases in state negative mood (worry/stress and anger/ frustration) were significantly associated with within-person increases in cortisol. When examining trait emotional functioning, adolescents with higher levels of depressive symptoms had slightly lower basal cortisol levels, and adolescents with higher levels of trait anger had a significantly stronger cortisol response to awakening. Several developmental effects were found-adolescents at higher stages of pubertal development had daytime basal cortisol curves that were more elevated, had a steeper diurnal decline, and showed a lesser cortisol awakening response, and cortisol responses to worry/stress increased with age. Cortisol levels were also higher at moments adolescents were alone rather than with others, an effect that declined significantly with age. Cortisol levels were also higher at moments adolescents were alone rather than with others, an effect that declined significantly with age. Results suggest that ongoing transactions occur between adolescents' everyday emotional experiences and their cortisol levels, and that adolescent cortisol activity is modified by age/pubertal stage and by trait emotional functioning.
