Cognitive processes in the aftermath of experiencing a major life stressor play an important role in the impact of the event on the person. Intrusive thoughts about the event are likely to be associated with continued distress, while deliberate rumination, aimed at understanding and problem-solving, should be predictive of posttraumatic growth (PTG). The Event Related Rumination Inventory (ERRI), designed to measure these two styles of rumination, is described and validation information is provided. Using a college student sample screened for having experienced highly stressful life events, data were obtained (N=323) to conduct an exploratory factor analysis that supported the two factors of the ERRI. Separate confirmatory factor analyses (CFA) on two additional samples (Ns=186 and 400) supported a two-factor model. The two ERRI factors were validated by comparison with related variables and by assessing their contributions to predicting distress and PTG in two samples (Ns=198 and 202) that had been combined to conduct the second CFA. Data indicate the ERRI has solid psychometric properties, captures variance not measured by stable differences in cognitive styles, and the separate factors are related to posttraumatic distress and growth as predicted by existing models of PTG.
经历重大生活应激源后，认知过程在该事件对个体的影响中起着重要作用。对该事件的侵入性思维很可能与持续的痛苦有关，而旨在理解和解决问题的深思熟虑的反刍则应该预示着创伤后成长（PTG）。旨在衡量这两种反刍风格的事件相关反刍问卷（ERRI）得到了描述和验证信息。使用经过筛选经历过高度应激性生活事件的大学生样本，获得了数据（N=323），以进行支持 ERRI 的两个因素的探索性因素分析。对另外两个样本（N=186 和 400）进行的单独验证性因素分析（CFA）支持了双因素模型。通过与相关变量进行比较，并通过评估它们在两个样本（N=198 和 202）中的贡献，对 ERRI 的两个因素进行了验证，这两个样本被合并进行了第二次 CFA。数据表明，ERRI 具有可靠的心理计量学特性，捕捉到了由认知风格稳定差异无法衡量的差异，并且独立因素与创伤后痛苦和成长相关，如现有 PTG 模型所预测的那样。
