Intrusive memories of trauma are recurrent distressing sensory-perceptual impressions of the traumatic event that enter consciousness spontaneously and unwanted. They often contain the worst moment/s ('hotspots') of the trauma memory and have primarily been studied in clinical populations after real trauma. Intrusive memories can also be studied using analogue trauma as an 'experimental psychology model'. Little is known about the features of analogue trauma hotspots. Here we report an ancillary analysis of data from a randomized controlled trial. Seventy non-clinical participants viewed a trauma film containing COVID-19 related footage. Features of hotspots/intrusive memories of the film were explored using linguistic analysis and qualitative content coding. Participants reported on average five hotspots (M = 9.5 words/hotspot). Akin to hotspots soon after real trauma, analogue hotspots/intrusions primarily contained words related to space. Most contained sensory features, yet few cognitions and emotions. Results indicate that features of analogue trauma hotspots mirror those of hotspots soon after real trauma, speaking to the clinical validity of this 'experimental psychology model'.ClinicalTrials.gov ID: NCT04608097, registered on 29/10/2020.
创伤侵入性记忆是指创伤事件反复出现的令人痛苦的感官知觉印象，这些印象会自发地、不受控制地进入意识。它们通常包含创伤记忆中最糟糕的时刻（“热点”），并且主要在经历过真实创伤的临床人群中进行研究。侵入性记忆也可以使用模拟创伤作为“实验心理学模型”进行研究。关于模拟创伤热点的特征，人们知之甚少。在这里，我们报告了一项随机对照试验的辅助分析数据。70 名非临床参与者观看了一部包含与 COVID-19 相关镜头的创伤电影。使用语言分析和定性内容编码来探索电影热点/侵入性记忆的特征。参与者报告平均有五个热点（每个热点 9.5 个单词）。与真实创伤后不久的热点类似，模拟热点/侵入性记忆主要包含与空间相关的词语。大多数包含感官特征，但很少有认知和情绪。结果表明，模拟创伤热点的特征与真实创伤后不久的热点特征相似，这证明了这种“实验心理学模型”的临床有效性。ClinicalTrials.gov ID：NCT04608097，于 2020 年 10 月 29 日注册。
