沉思是青少年和成年人出现严重抑郁和焦虑症状的一个公认的危险因素。尽管沉思和内在化精神病理学之间有很强的关联性，但研究可能导致沉思反应风格的因素的研究还很少。在目前的研究中，我们考察了社会环境经历是否与沉思有关。具体地说，我们评估了自我报告的压力生活事件是否预示着随后沉思的增加。我们还调查了沉思是否作为自我报告的应激性生活事件和内化症状之间的纵向联系的一种机制。在两个不同的纵向样本中评估了自我报告的应激性生活事件、沉思以及抑郁和焦虑的症状。在跨越7个月的3个时间点对早期青少年(N=1,065)进行了评估。在跨越12个月的两个时间点对成人样本(N=1,132)进行了评估。在这两个样本中，自我报告的压力生活事件暴露在纵向上与更多的沉思有关。此外，沉思在两个样本中的自我报告压力源与焦虑症状之间的纵向关系以及在成人样本中自我报告的生活事件与抑郁症状之间的关系中起中介作用。找出心理和神经生物学机制来解释在应激源之后更倾向于沉思，这仍然是未来研究的重要目标。这项研究为应激性生活事件在形成对痛苦的特征反应中的作用提供了新的证据，特别是对沉思的参与，强调了旨在预防抑郁和焦虑发作的干预措施的潜在有用目标。
Rumination is a well-established risk factor for the onset of major depression and anxiety symptomatology in both adolescents and adults. Despite the robust associations between rumination and internalizing psychopathology, there is a dearth of research examining factors that might lead to a ruminative response style. In the current study, we examined whether social environmental experiences were associated with rumination. Specifically, we evaluated whether self-reported exposure to stressful life events predicted subsequent increases in rumination. We also investigated whether rumination served as a mechanism underlying the longitudinal association between self-reported stressful life events and internalizing symptoms. Self-reported stressful life events, rumination, and symptoms of depression and anxiety were assessed in 2 separate longitudinal samples. A sample of early adolescents (N = 1,065) was assessed at 3 time points spanning 7 months. A sample of adults (N = 1,132) was assessed at 2 time points spanning 12 months. In both samples, self-reported exposure to stressful life events was associated longitudinally with increased engagement in rumination. In addition, rumination mediated the longitudinal relationship between self-reported stressors and symptoms of anxiety in both samples and the relationship between self-reported life events and symptoms of depression in the adult sample. Identifying the psychological and neurobiological mechanisms that explain a greater propensity for rumination following stressors remains an important goal for future research. This study provides novel evidence for the role of stressful life events in shaping characteristic responses to distress, specifically engagement in rumination, highlighting potentially useful targets for interventions aimed at preventing the onset of depression and anxiety.
