Background: The COVID-19 pandemic has escalated the global need for remotely delivered and scalable interventions after psychological trauma. A brief intervention involving a computer game as an imagery-competing task has shown promising results for reducing the number of intrusive memories of trauma—one of the core clinical symptoms of posttraumatic stress disorder. To date, the intervention has only been delivered face-to-face. To be tested and implemented on a wider scale, digital adaptation for remote delivery is crucial. An important first step is to develop digitalized intervention materials in a systematic way based on feedback from clinicians, researchers, and students in preparation for pilot testing with target users. Objective: The first aim of this study is to obtain and analyze qualitative feedback on digital intervention materials, namely two animated videos and two quizzes that explain the target clinical symptoms and provide intervention instructions. The second aim is to refine the digitalized materials based on this feedback. Methods: We conducted semistructured interviews with 12 participants who had delivered or had knowledge of the intervention when delivered face-to-face. We obtained in-depth feedback on the perceived feasibility of using the digitalized materials and suggestions for improvements. Interviews were assessed using qualitative content analysis, and suggested improvements were evaluated for implementation using a systematic method of prioritization. Results: A total of three overarching themes were identified from the data. First, participants were highly positive about the potential benefits of using these digital materials for remote delivery, reporting that the videos effectively conveyed key concepts of the symptom and its treatment. Second, some modifications to the materials were suggested for improving clarity. On the basis of this feedback, we made nine specific changes. Finally, participants raised some key challenges for remote delivery, mainly in overcoming the lack of real-time communication during the intervention. Conclusions: Clinicians, researchers, and clinical psychology students were overall confident in the use of digitalized materials to remotely deliver a brief intervention to reduce intrusive memories of trauma. Guided by participant feedback, we identified and implemented changes to refine the intervention materials. This study lays the groundwork for the next step: pilot testing remote delivery of the full intervention to trauma survivors. Trial Registration:

数字化简短干预以减少心理创伤的侵入性记忆：定性访谈研究

背景： COVID-19大流行已经扩大了全球对心理创伤后远程提供可扩展干预措施的需求。一项涉及计算机游戏作为图像竞争任务的简短干预措施已显示出减少创伤性创伤性记忆（创伤后应激障碍的核心临床症状之一）的数量很有希望的结果。迄今为止，干预措施只是面对面提供的。要进行更大规模的测试和实施，远程交付的数字适应至关重要。重要的第一步是根据临床医生，研究人员和学生的反馈，以系统的方式开发数字化干预材料，以准备对目标用户进行试点测试。客观的：这项研究的第一个目的是获得和分析有关数字干预材料的定性反馈，即两个动画视频和两个测验，它们解释了目标临床症状并提供了干预指导。第二个目标是基于此反馈来优化数字化材料。方法：我们进行了半结构化访谈，采访了12位当面交付或已经知道干预措施的参与者。我们获得了关于使用数字化材料的可行性的深入反馈，并提出了改进建议。使用定性内容分析对访谈进行评估，并使用系统的优先排序方法对改进的实施进行评估。结果：从数据中识别出总共三个总体主题。首先，与会人员对使用这些数字资料进行远程分发的潜在好处表示高度肯定，并说视频有效地传达了症状及其治疗的关键概念。其次，建议对材料进行一些修改以提高清晰度。在此反馈的基础上，我们进行了九项具体更改。最后，参与者提出了一些远程交付的关键挑战，主要在于克服干预期间缺乏实时通信的问题。结论：临床医生，研究人员和临床心理学专业的学生对使用数字化材料远程提供简短的干预措施以减少创伤的创伤记忆总体上充满信心。在参与者反馈的指导下，我们确定并实施了更改以完善干预材料。这项研究为下一步工作奠定了基础：对创伤幸存者进行全面干预的远程交付试点测试。试用注册：
