负性情绪（NE）的气质特征在经历显著生活压力的成年人中的适应不良中起着重要作用。然而，在经历早期逆境的儿童中，尚未建立儿童NE与随后相关的行为、情绪和生物失调之间的前瞻性关系。使用纵向样本的青年经历了父母离婚在童年（N = 160; 53%男性; 83%白色），我们测试的假设，童年NE将预测生理，情绪和行为失调15年后。在9 ~ 12岁的青少年中，根据母亲的报告评估NE。15年后，年轻的成年人（平均年龄= 25.55岁）参加了心理社会压力任务，以评估皮质醇的反应，并报告了内化症状和有问题的酒精使用。结构方程模型显示，较高的儿童NE预测显着更大的酒精使用，内化症状，总皮质醇输出在压力任务15年后。重要的是，这些发现在调整了儿童内化症状后仍然有效。此外，有问题的酒精使用与更大的皮质醇反应和内化症状有关。研究结果表明，儿童NE是一个关键的风险标志，在成年后的年轻人之间的风险青年相互关联的形式失调。
The temperamental trait of negative emotionality (NE) plays an important role in maladaptation among adults experiencing significant life stress. However, the prospective relation between childhood NE and subsequent interrelated behavioral, emotional, and biological dysregulation in later life has not yet been established among children who experience early adversity. Using a longitudinal sample of youth who experienced parental divorce during childhood (N = 160; 53% male; 83% White), we tested the hypothesis that childhood NE would predict physiological, emotional, and behavioral dysregulation 15 years later. NE was assessed by maternal report when youth were between 9 and 12 years old. Fifteen years later, young adults (mean age = 25.55 years) participated in a psychosocial stress task to assess cortisol reactivity and reported on internalizing symptoms and problematic alcohol use. Structural equation modeling revealed that higher childhood NE predicted significantly greater alcohol use, internalizing symptoms, and total cortisol output during a stress task 15 years later. Importantly, these findings held after adjusting for childhood internalizing symptoms. In addition, problematic alcohol use was associated with greater cortisol reactivity and internalizing symptoms. Findings suggest that childhood NE is a critical risk marker for interrelated forms of dysregulation in young adulthood among at-risk youth.
