Co-rumination (defined as perseverative, negatively-focused discussions about problems) has been linked to internalizing symptoms, especially following psychosocial stress. The sudden outbreak of SARS-CoV-2, the virus causing Coronavirus disease 2019 (COVID-19) during Spring 2020 may have been a common focus of co-rumination. Conceptualized within a contextual behavioral science framework, the current study examined pandemic-focused co-rumination and its components: co-brooding (i.e., passively dwelling on concerns and associated consequences and negative emotions in a dyadic context) and co-reflection (i.e., repetitively discussing problems dyadically to enhance insight). A total of 320 undergraduates (62 %, female, 37 % male, 1 % non-binary gender) completed an online survey from late April-early May 2020 shortly after their universities abruptly ended in-person instruction and removed students from campus. COVID-19-focused co-rumination (specifically co-brooding) was associated with higher levels of internalizing symptoms. Co-brooding and co-reflection each moderated the association between COVID-19 stress exposure and a) internalizing symptoms (COVID-related fears and depressive symptoms) and b) committed action, but in opposite directions, with co-brooding predicting increased symptoms and decreased committed action, and co-reflection predicting the opposite. Results suggest that when the nature of social support-seeking discussions promote psychological flexibility via increased perspective and understanding (vs. dwelling on negative content of experiences), they may ameliorate emotional distress and promote committed action following stress exposure.

共同思考（定义为关于问题的坚持、消极的讨论）与内化症状有关，尤其是在社会心理压力之后。SARS-CoV-2（2020 年春季引起 2019 年冠状病毒病（COVID-19）的病毒）的突然爆发可能是共同思考的共同焦点。本研究在情境行为科学框架内进行了概念化，研究了以大流行为重点的共同反思及其组成部分：共同思考（即在二元情境中被动地关注关注和相关后果以及负面情绪）和共同反思（即，以二元方式重复讨论问题以增强洞察力）。共有 320 名本科生（62 %，女性，37 % 男性，1% 的非二元性别）在 2020 年 4 月下旬至 2020 年 5 月上旬期间完成了一项在线调查，因为他们的大学突然结束了面对面教学并将学生从校园中带走。以 COVID-19 为重点的共同思考（特别是共同孵化）与更高水平的内化症状相关。共同思考和共同反思各自缓和了 COVID-19 压力暴露与 a) 内化症状（与 COVID 相关的恐惧和抑郁症状）和 b) 采取相反方向的行动之间的关联，共同思考预测增加的症状和减少的承诺行动，以及共同反映预测相反的情况。结果表明，当寻求社会支持的讨论的性质通过增加视角和理解（而不是沉迷于体验的负面内容）促进心理灵活性时，它们可能会减轻情绪困扰并促进压力暴露后的坚定行动。
