摘要反刍思维是一种在多种精神障碍中常见的病理性的习惯性思维模式，与抑郁、焦虑、创伤后应激和强迫障碍等精神障碍的症状严重程度、治疗结局和社会功能结局密切相关。近年来反刍思维成为了精神障碍临床诊疗关注的热点，但反刍思维的研究仍面临挑战，主要包括概念模糊、缺乏一致的评估工具、病理机制不明确以及缺乏有效的干预方法等。为增强对不同精神障碍反刍思维的理解，本文通过回顾国内外相关文献，概述介绍反刍思维的概念、评估、病理机制和干预手段，以期为反刍思维的临床诊疗提供借鉴和参考。

abstractsRumination is a pathological habitual thinking pattern commonly observed in various mental disorders. It is closely associated with the severity of symptoms, treatment outcomes, and social functioning outcomes in conditions such as depression, anxiety, post-traumatic stress disorder, and obsessive-compulsive disorder. In recent years, rumination has become a focal point in the clinical diagnosis and treatment of mental disorders. However, research on rumination still faces challenges, including conceptual ambiguity, lack of consistent assessment tools, unclear pathological mechanisms, and a shortage of effective intervention methods. This paper conducts a comprehensive review by examining relevant domestic and international literature to enhance our understanding of rumination across different mental disorders. The review encompasses the concepts, assessments, pathological mechanisms, and intervention methods of rumination, aiming to provide insights and references for the clinical diagnosis and treatment of rumination.
