Intrusive memories occur frequently after potentially traumatic events and form a core symptom of posttraumatic stress disorder (PTSD) if they persist. The translational approach of visuospatial interventions tries to target those intrusive memories in order to reduce their frequency predominantly using an intervention including as one component the computer game Despite promising results, the application of has critical drawbacks, e.g., potential commercial or copyright issues. Furthermore, it remains unclear whether it is this specific game or, as predicted by theory, a visuospatial task that leads to the effect. This study hence aims to compare the effect of with an alternative, bespoke visuospatial task: developed for the current purpose.
= 120 healthy participants watched a trauma film and recorded their intrusive memories in a diary for 6 days. Three days after watching the film, they were randomized to 3 groups and after memory reactivation cue received either or or (no task). Prior to intervention 8 participants reported zero intrusive memories to the film and were excluded from further analyses, therefore 112 participants were included in the analysis.
A mixed Poisson regression model revealed that the group had significantly less frequent intrusive memories after the intervention compared to the control condition (approximately 43%, = 0.0013). There was no significant difference for the group compared to (17% less frequent, = 0.3798).
Our results suggest that visuospatial tasks other than -in this case, -can also lead to a reduction in intrusive memories when administered 3 days after a trauma film. This strengthens the assumption that it is not specifically the game , but rather the visuospatial nature of the task, that is responsible for the reduction. Aspects of further investigating the potential of as well as clinical implications are discussed.
侵入性记忆在潜在创伤性事件后频繁出现，如果持续存在则构成创伤后应激障碍（PTSD）的核心症状。视觉空间干预的转化方法试图针对这些侵入性记忆，主要通过一种包括电脑游戏作为一个组成部分的干预措施来降低其出现频率。尽管取得了有前景的结果，但[具体游戏名称]的应用存在关键缺陷，例如潜在的商业或版权问题。此外，尚不清楚是这款特定游戏，还是如理论所预测的视觉空间任务导致了这种效果。因此，本研究旨在将[具体游戏名称]的效果与另一种为当前目的开发的定制视觉空间任务：[定制任务名称]进行比较。
120名健康参与者观看了一部创伤影片，并在日记中记录他们的侵入性记忆，为期6天。观看影片三天后，他们被随机分为3组，在记忆重新激活提示后，分别接受[具体游戏名称]或[定制任务名称]或[无任务]。在干预前，8名参与者报告对影片没有侵入性记忆，被排除在进一步分析之外，因此112名参与者被纳入分析。
混合泊松回归模型显示，与对照条件相比，[具体游戏名称]组在干预后侵入性记忆的出现频率显著降低（约43%，P = 0.0013）。与[定制任务名称]组相比，[具体游戏名称]组没有显著差异（频率低17%，P = 0.3798）。
我们的结果表明，在创伤影片观看三天后进行视觉空间任务（在本案例中为[定制任务名称]），也可以导致侵入性记忆减少。这强化了这样一种假设，即并非特定的[具体游戏名称]游戏，而是任务的视觉空间性质导致了这种减少。文中讨论了进一步研究[定制任务名称]潜力以及临床意义的相关方面。
