Abstract：
UNASSIGNED: Rumination is a well-established contributor to the severity of depression and anxiety. It is unknown, however, whether individual differences in the temporal dynamics of rumination over time predict longitudinal increases in depression or anxiety.
UNASSIGNED: The current study examined whether the dynamic indices of ruminative inertia and variability assessed over 14 days via ecological momentary assessment predicted change in symptoms of depression, general anxiety, and social anxiety at a 90-day follow-up (n = 115).
UNASSIGNED: Controlling for ruminative variability, baseline levels of the dependent variable, sex, and mean levels of momentary rumination, ruminative inertia did not predict change in symptoms of depression, general anxiety, or social anxiety at the 90-day follow-up. In contrast, greater ruminative variability predicted increases in symptoms of both depression and social anxiety but not general anxiety at follow-up. Individuals endorsing higher baseline levels of depressive symptoms demonstrated greater amounts of inertia and variability in their momentary rumination. Greater ruminative variability but not inertia was also associated with higher baseline levels of general anxiety and social anxiety.
UNASSIGNED: These results suggest that ruminative variability may be a risk factor for increases in symptoms of depression and social anxiety over time and a potentially useful target for clinical intervention.

摘要：
■沉思是导致抑郁和焦虑严重程度的公认因素。它是未知的，然而,随着时间的推移，沉思的时间动态中的个体差异是否可以预测抑郁或焦虑的纵向增加。
■当前的研究检查了通过生态瞬时评估在14天内评估的反思性惯性和变异性的动态指标是否可以预测抑郁症状的变化，一般焦虑,以及90天随访时的社交焦虑（n=115）。
■控制反思性变异性，因变量的基线水平，性别,和平均短暂的沉思水平，反思性惯性并不能预测抑郁症状的变化，一般焦虑,或者在90天的随访中出现社交焦虑。相比之下,更高的反思性变异性预测抑郁症和社交焦虑症状的增加，但在随访时不是一般焦虑。支持较高基线水平的抑郁症状的个体在其瞬时反思性中表现出更大的惯性和变异性。更大的反思性变异性而不是惯性也与更高的一般焦虑和社交焦虑基线水平相关。
■这些结果表明，反思性变异性可能是抑郁症和社交焦虑症状随时间增加的危险因素，并且是临床干预的潜在有用目标。
