Rumination is a well-established transdiagnostic vulnerability. However, few studies have explored the transdiagnostic role of event-related rumination. Moreover, there is a paucity of longitudinal studies clarifying the temporal precedence of event-related rumination. Therefore, this study aimed to longitudinally examine the mediating paths of event-related rumination between perceived stress and diverse symptomatic dimensions.
A representative sample of Korean adults ( = 316) was recruited online and they completed a package of self-reported measures twice over a one-year period. Using prospective two-wave data collected during the pandemic, longitudinal indirect effects were examined using the hypothesized path model.
As expected, intrusive rumination acted as a transdiagnostic mediator in both internalizing and externalizing psychopathology and was positively associated with all subsequent symptom dimensions, except mania. Meanwhile, the beneficial role of deliberate rumination was less-transdiagnostic.
These initial findings suggest that event-related rumination could be considered a transdiagnostic mediator and a target for prevention and intervention to maintain mental health during and after the pandemic.
反刍是一种已被充分证实的跨诊断易感性因素。然而，很少有研究探讨与事件相关的反刍的跨诊断作用。此外，缺乏纵向研究来阐明与事件相关的反刍的时间先后顺序。因此，本研究旨在纵向考察与事件相关的反刍在感知压力和多种症状维度之间的中介路径。
通过网络招募了具有代表性的韩国成年人样本（n = 316），他们在一年时间内分两次完成了一套自我报告测量。利用在疫情期间收集的前瞻性两波数据，使用假设路径模型检验纵向间接效应。
正如预期的那样，侵入性反刍在内化和外化精神病理学中均充当跨诊断中介，并且除躁狂症外，与所有后续症状维度均呈正相关。同时，刻意反刍的有益作用的跨诊断性较低。
这些初步发现表明，与事件相关的反刍可被视为一种跨诊断中介，以及在疫情期间及之后维持心理健康的预防和干预目标。
