The current study sought to experimentally assess the differential effects of analytical ruminative processing and distraction on the experience of self-referent naturally occurring intrusive memories in a sample of dysphoric (BDI-II > or = 12) participants. Seventy-seven undergraduate participants completed a memory interview to elicit details about a self-referential intrusion and were randomly assigned to either an analytical rumination or distraction condition. Subsequent to the rumination induction, participants rated their intrusive memory as more negative, more distressing, and more evocative of a negative emotional response compared to participants who were allocated to the distraction induction. Inducing analytical rumination also resulted in participants reporting worse (i.e., more sad) mood relative to those in the distraction condition. The findings align with the suggestion that depressed individuals may get caught up in a ruminative cycle that, due to the documented effects of analytical self-focus, exacerbate the emotional response elicited by intrusions and perpetuate biased attentional focus on them. Directions for future investigations of the cognitive processes that are important in the maintenance of intrusions in depressive disorders are discussed.
本研究旨在通过实验评估分析性反刍加工和分心对抑郁（BDI-II≥12）被试自然发生的自我参照侵入性记忆体验的差异影响。77 名本科生完成了记忆访谈，以引出关于自我参照侵入的详细信息，并被随机分配到分析性反刍或分心条件中。在反刍诱导之后，与被分配到分心诱导的参与者相比，参与者认为他们的侵入性记忆更消极、更痛苦，更能引起负面情绪反应。与分心条件相比，诱导分析性反刍也导致参与者报告更糟糕的（即更悲伤）情绪。这些发现与以下观点一致，即抑郁个体可能陷入一种反刍循环，由于分析性自我关注的记录影响，加剧了侵入性引发的情绪反应，并使他们对其产生偏见的注意力持续集中。讨论了未来对抑郁障碍中侵入性维持的重要认知过程的研究方向。
