Introduction: Researchers have proposed several theories of depressive rumination. To compare among them, we conducted a joint factor analysis. Methods: An online sample (n = 498) completed four rumination questionnaires and the Beck Depression Inventory. We examined associations between emerging factors and depressive symptoms. Results: Most commonly, people ruminated about solving problems in their lives, followed by the causes or consequences of negative situations. They least commonly ruminated about their symptoms and sadness. Thoughts about symptoms and causes or consequences of negative situations uniquely related to depressive symptoms. There was a circular covariance relation between depressive symptoms, thoughts about causes or consequences, and problem-solving, suggesting that symptoms are regulated by a negative feedback loop involving problem-solving. This feedback was not present unless models included thoughts about causes or consequences, suggesting that these thoughts benefit problem-solving. Discussion: Depressive rumination may be a dynamic process involving various thoughts, with different combinations of thoughts having different consequences for depression.

抑郁性反刍的性质及其与抑郁症状的关系

简介：研究人员提出了几种抑郁性反刍理论。为了比较它们，我们进行了联合因素分析。方法：在线样本（n = 498）完成了四份反刍问卷和贝克抑郁量表。我们检查了新出现的因素与抑郁症状之间的关联。结果：最常见的是，人们反复思考解决生活中的问题，其次是消极情况的原因或后果。他们最不常反思自己的症状和悲伤。关于与抑郁症状唯一相关的负面情况的症状和原因或后果的想法。抑郁症状、对原因或后果的想法以及解决问题的能力之间存在循环协方差关系，表明症状受到涉及解决问题的负反馈循环的调节。除非模型包含有关原因或后果的想法，否则不会出现这种反馈，这表明这些想法有助于解决问题。讨论：抑郁的反刍可能是一个涉及各种想法的动态过程，不同的想法组合对抑郁有不同的后果。
