虽然青春期的特点是增加消极的生活事件和内化的问题，很少有研究调查这种关联作为一个持续的纵向过程。此外，虽然这些现象之间的联系程度存在相当大的个体差异，但对这些差异的起源知之甚少。本研究探讨了早期生活压力（ELS）暴露和青少年早期纵向下午皮质醇水平的预测内化症状和负性生活事件之间的协变在高中。ELS通过母亲在婴儿期的报告进行评估，皮质醇的测量来自11岁，13岁和15岁的评估。在15岁、17岁和18岁时评估生活事件和内化症状。一个两级分层线性模型显示，ELS和皮质醇的内化症状和负性生活事件的协变的独立预测。与ELS水平较低的青少年相比，ELS暴露的青少年表现出更紧密的内在化症状和负性生活事件之间的协变。纵向下午皮质醇较低的青少年表现出更紧密的负性生活事件和内化症状之间的协变，而那些皮质醇较高的表现出较弱的协变，部分原因是当面对较少的负性生活事件时，内化症状的水平增加。
Although adolescence is marked by increased negative life events and internalizing problems, few studies investigate this association as an ongoing longitudinal process. Moreover, while there are considerable individual differences in the degree to which these phenomena are linked, little is known about the origins of these differences. The present study examines early life stress (ELS) exposure and early-adolescent longitudinal afternoon cortisol level as predictors of the covariation between internalizing symptoms and negative life events across high school. ELS was assessed by maternal report during infancy, and the measure of cortisol was derived from assessments at ages 11, 13, and 15 years. Life events and internalizing symptoms were assessed at ages 15, 17, and 18 years. A two-level hierarchical linear model revealed that ELS and cortisol were independent predictors of the covariation of internalizing symptoms and negative life events. Compared to those with lower levels of ELS, ELS-exposed adolescents displayed tighter covariation between internalizing symptoms and negative life events. Adolescents with lower longitudinal afternoon cortisol displayed tighter covariation between negative life events and internalizing symptoms, while those with higher cortisol demonstrated weaker covariation, partially due to increased levels of internalizing symptoms when faced with fewer negative life events.
