Although recent research demonstrates that intrusive memories represent an overlapping cognitive feature of depression and post-traumatic stress disorder (PTSD), there is still a general paucity of research investigating the prevalence and maintenance of intrusive memories in depression. The current study investigated the association between a range of cognitive avoidant mechanisms that characterize PTSD samples (i.e., suppression, rumination, emotional detachment, and an observer vantage perspective) and intrusive memories of negative autobiographical events in relation to dysphoria. Hypotheses were based on the proposition that employment of these cognitive mechanisms would hinder the emotional processing of the negative event, thus contributing to the maintenance of intrusions. Results supported an association between negative intrusive memories, dysphoria, and avoidant mechanisms. Significant differences were also found between field and observer memories and measures of emotional detachment and rumination. Implications relating to intrusive memory maintenance and treatment approaches are discussed.
尽管最近的研究表明，侵入性记忆是抑郁症和创伤后应激障碍（PTSD）的一个重叠认知特征，但目前仍普遍缺乏对抑郁症中侵入性记忆的患病率和维持情况的研究。本研究调查了一系列表征PTSD样本的认知回避机制（即抑制、沉思、情绪超脱和观察者视角）与与烦躁不安相关的负面自传体事件的侵入性记忆之间的关联。研究假设基于这样的观点，即使用这些认知机制会阻碍对负面事件的情绪处理，从而导致侵入性记忆的维持。结果支持了负面侵入性记忆、烦躁不安和回避机制之间的关联。在现场记忆和观察者记忆以及情绪超脱和沉思的测量方面也发现了显著差异。文中讨论了与侵入性记忆维持和治疗方法相关的意义。
