Traumatic events are often perceived as unforgettable, yet scientific evidence highlights the complexity of memory recall in the aftermath of traumatic experiences. While some studies observed amplification of traumatic memory, others reveal rapid forgetfulness and falsification of details. The primary objective of this study is to investigate how initial memories of the Beirut Port Blast in 2020 fluctuate over time. Going beyond full-threshold self-reported post-traumatic stress disorder (PTSD) and self-reported acute stress disorder (ASD), the research aims to explore subthreshold self-reported PTSD and individual self-reported ASD symptoms as potential predictors of recall bias among healthcare workers. This study draws on data from four waves of the ongoing B.L.A.S.T. (Beirut Longitudinal Assessment Study of Trauma) study which spans so far over a period of two years. Being a clinical professional and having higher self-reported ASD symptoms in wave 1, specifically intrusion symptoms, were associated with recall diminishment. Higher self-reported PTSD, subthreshold self-reported PTSD diagnoses (six plus or majority) and higher anxiety scores were significantly associated with exaggeration of recall. The study underscores the importance of assessing a broad range of symptoms, beyond conventional diagnoses, to gain a comprehensive understanding of how traumatic memories are recalled and potentially altered over time.
创伤性事件通常被认为是令人难忘的，但科学证据凸显了创伤经历后记忆回忆的复杂性。虽然一些研究观察到创伤记忆的增强，但另一些研究则揭示了快速遗忘和细节伪造的现象。本研究的主要目的是调查2020年贝鲁特港口爆炸的初始记忆如何随时间波动。该研究超越了完全阈值的自我报告创伤后应激障碍（PTSD）和自我报告急性应激障碍（ASD），旨在探索亚阈值自我报告的PTSD和个体自我报告的ASD症状，作为医护人员回忆偏差的潜在预测因素。本研究借鉴了正在进行的B.L.A.S.T.（贝鲁特创伤纵向评估研究）的四轮数据，该研究迄今跨越了两年时间。作为临床专业人员，在第一波中自我报告的ASD症状较高，特别是侵入性症状，与回忆减少有关。较高的自我报告PTSD、亚阈值自我报告PTSD诊断（六个及以上或大多数）和较高的焦虑得分与回忆夸大显著相关。该研究强调了评估广泛症状的重要性，超越传统诊断，以全面了解创伤记忆如何被回忆以及随着时间推移可能如何改变。
