过度自传式记忆（OGM）已被发现是抑郁症和创伤相关精神病理（如创伤后应激障碍）的重要认知现象，研究人员一直对更好地理解导致这种脆弱性因素的因素感兴趣。迄今为止最突出的OGM机制模型是CaR-FA-X模型。该模型提出了影响OGM的三个过程：捕获和反刍、功能性回避和执行控制受损。作者通过评估38项研究，回顾了CaR-FA-X模型的支持现状，这些研究已经检查了OGM和模型的一个或多个机制。总的来说，这些研究有力地支持了OGM与反刍和执行控制受损之间的联系。OGM似乎也是一种认知回避策略，有证据表明，在发生厌恶事件后，避免提取特定记忆可以减少痛苦，至少在短期内如此。强调了尚未解决的重要问题，包括捕获现象的性质，创伤在功能性回避中的作用，以及功能性回避的发展性质。对未来的研究提出了建议，以加强对导致OGM的因素的理解。
Overgeneral autobiographical memory (OGM) has been found to be an important cognitive phenomenon with respect to depression and trauma-related psychopathology (e.g., posttraumatic stress disorder), and researchers have been interested in better understanding the factors that contribute to this proposed vulnerability factor. The most prominent model of mechanisms underlying OGM to date is CaR-FA-X model. This model proposes that three processes influence OGM: capture and rumination, functional avoidance, and impaired executive control. The author reviews the current state of support for the CaR-FA-X model by evaluating 38 studies that have examined OGM and one or more mechanisms of the model. Collectively, these studies reveal robust support for associations between OGM and both rumination and impaired executive control. OGM also appears to be a cognitive avoidance strategy, and there is evidence that avoiding the retrieval of specific memories reduces distress after an aversive event, at least in the short term. Important issues that have been left unresolved are highlighted, including the nature of the capture phenomenon, the role of trauma in functional avoidance, and the developmental nature of functional avoidance. Recommendations for future research that will enhance understanding of the factors that contribute to OGM are suggested.
