尽管该领域的大多数研究都集中在童年应激源作为精神病理学的风险因素上，但也有大量文献聚焦于中等类型的应激事件可能产生的强化作用。本研究对163名早期青少年(女性占52%，高加索人占51%)进行了多波研究，调查了近期生活应激源对抑郁症状的预期变化的影响，以及童年时期中度逆境的历史是否会缓和这种关系。用四波数据进行分层线性建模。有较多中重度早期生活事件的青少年在过去9个月内对近端应激事件的变化表现出迟钝的抑郁症状反应，而较少早期中重度逆境经历的青少年。这些结果是在控制了种族、性别、严重的早期生活压力和四波数据中的平均压力等受试者之间的因素后得出的。研究结果表明，更多地暴露在中等的童年压力源中，可能会缓冲随后的压力源的负面影响，这表明了研究早期生活压力的影响的微妙发展方法的重要性。
Although the majority of research in the field has focused on childhood stressors as a risk factor for psychopathology, a burgeoning body of literature has focused on the possible steeling effect of moderate types of stressful events. The current study investigated the effects of proximal life stressors on prospective changes in depressive symptoms, and whether a history of moderate childhood adversity would moderate this relationship in a multi-wave study of a diverse community sample of early adolescents (N = 163, 52% female, 51% Caucasian). Hierarchical linear modeling was run with four waves of data. Adolescents with greater moderately severe early life events evinced a blunted depressive symptom response to changes in proximal stressful events in the previous 9 months, compared to those with fewer early moderately severe experiences of adversity. These results held after controlling for between-subject factors such as race, gender, severe early life stress, and average stress over the four waves of data. Findings indicate that greater exposure to moderate childhood stressors may buffer against the negative effects of subsequent stressors, suggesting the importance of a nuanced developmental approach to studying the effects of early life stress.
