Adolescents change how they cope with stress across different situations, but also differ from one another in their general capacity to cope. The current study examined whether cortisol reactivity to perceived daily stress varies with both situational (within-person) and individual (between-person) differences in coping. First-year college students (N=63; Mage=18.85) provided 15 stress-coping diaries and 15 corresponding saliva samples across 3 weekdays. Results from hierarchical linear growth models revealed that perceiving greater stress than usual in the last hour was significantly associated with elevations in cortisol (relative to diurnal patterning) only during situations characterized by greater than usual diary-reported engagement coping. Regarding individual differences, perceiving greater stress than usual was significantly associated with elevations in cortisol only for adolescents below average on trait measures of engagement coping or belief in their ability to handle stress. Findings indicate that cortisol reactivity to daily stress varies with both situational variation and individual differences in coping.
青少年在不同情境下应对压力的方式会有所变化，而且他们在总体应对能力上也存在个体差异。本研究考察了皮质醇对感知到的日常压力的反应是否会因情境（个体内部）和个体（个体之间）在应对方式上的差异而有所不同。大学一年级学生（N = 63；平均年龄 = 18.85岁）在三个工作日内提供了15份压力应对日记和15份相应的唾液样本。分层线性增长模型的结果显示，仅在日记报告的参与式应对高于平常的情境中，相较于平常，在过去一小时内感知到更大的压力才与皮质醇升高（相对于昼夜模式）显著相关。关于个体差异，仅对于在参与式应对特质测量或应对压力能力信念方面低于平均水平的青少年，相较于平常感知到更大的压力才与皮质醇升高显著相关。研究结果表明，皮质醇对日常压力的反应会因情境变化和个体在应对方式上的差异而有所不同。
