The goal of the current study was to examine the role of brooding rumination in children at risk for depression. We found that children of mothers with a history of major depression exhibited higher levels of brooding rumination than did children of mothers with no depression history. Examining potential mechanisms of this risk, we found no evidence for shared genetic influences (BDNF or 5-HTTLPR) or modeling of mothers' rumination. However, we did find that children with a history of prior depressive disorders exhibited higher current levels of brooding rumination than children with no depression history. Importantly, children's brooding predicted prospective onsets of new depressive episodes over a 20-month follow-up even when we statistically controlled for depressive symptom levels at the initial assessment, suggesting that the predictive effect of brooding rumination in children was not due simply to co-occurring depressive symptoms.
本研究旨在探讨沉思反刍在抑郁风险儿童中的作用。我们发现，有抑郁史母亲的孩子比没有抑郁史母亲的孩子表现出更高水平的沉思反刍。研究这种风险的潜在机制，我们没有发现共同的遗传影响（BDNF 或 5-HTTLPR）或母亲反刍的模仿的证据。然而，我们确实发现，有先前抑郁障碍史的儿童比没有抑郁史的儿童当前表现出更高水平的沉思反刍。重要的是，即使我们在初始评估时统计控制了抑郁症状水平，儿童的沉思反刍也预测了 20 个月随访中新的抑郁发作，这表明儿童沉思反刍的预测效应并非仅仅归因于同时存在的抑郁症状。
