In this study, we explored whether nightmare distress mediated the correlation between autobiographical memory specificity and depression. 112 participants provided their most recent dreams that happened within one month, and finished some scales that measured depression, autobiographical memory specificity, and nightmare distress. In line with our hypothesis, nightmare distress was the mediator that played a role in the relationship between autobiographical memory specificity and depression. In addition, we found that both nightmare distress and autobiographical memory specificity were correlated with the impact of a dream on one’s life story. By contrast, contrary to our hypothesis, we did not find any correlation between autobiographical memory specificity, or nightmare distress, and dream bizarreness. Potential implications from these results were discussed.本研究旨在探讨噩梦痛苦（nightmare distress）是否在自传体记忆特异性（autobiographical memory specificity）与抑郁之间的关联中发挥中介作用。本研究共招募112名被试，要求其提供近一个月内的最新梦境，并完成用于评估抑郁、自传体记忆特异性及噩梦痛苦的相关量表。与我们的研究假设一致，噩梦痛苦确实在自传体记忆特异性与抑郁的关联中起到了中介作用。此外，本研究还发现，噩梦痛苦与自传体记忆特异性均与梦境对个体人生叙事的影响存在显著相关。与之相反，与我们的初始假设不符的是，本研究未发现自传体记忆特异性或噩梦痛苦与梦境荒诞性（dream bizarreness）之间存在任何关联。最后，本研究对上述结果的潜在研究意义进行了讨论。
