自然灾害会影响心理健康，导致抑郁、焦虑和创伤后应激障碍（PTSD）的症状。回放剧场（英语：Playback Theatre，PT）是一种即兴表演形式，演员在其中回放观众讲述的个人故事。PT是否可以在灾后环境中治疗尚不清楚。我们使用了一系列PT表现，并研究了2017年8月在德克萨斯州休斯顿发生的飓风哈维影响的13人样本中的抑郁，焦虑和PTSD症状水平。在PT表演之前和之后，还研究了大脑成像，特别是杏仁核的静息状态功能连接。在2019年1月至2019年2月的一系列4次PT表演后，焦虑（p = 0.001，科恩d = -1.25）和创伤后应激障碍（p = 0.002，科恩d = -1.0）症状均显著下降。抑郁减少不显著。我们在一系列表演之前和之后进行了静息状态功能连接性（RSFC）MRI。我们使用右侧和左侧杏仁核作为种子进行RSFC分析，发现PT后左侧杏仁核和双侧缘上回之间的连通性增加。与默认模式和显着性网络的双边超边缘连接也增加，这与焦虑分数的降低相关。PT可以为灾难引起的焦虑提供一种干预形式。左杏仁核/缘上回连接的增加可能是潜在的机制。
Natural disasters can affect mental health and result in symptoms of depression, anxiety, and post-traumatic stress disorder (PTSD). Playback Theatre (PT) is a form of improvisation where actors play-back personal stories told by audience members. Whether PT can be therapeutic in post-disaster settings is not known. We used a series of PT performances and studied levels of depression, anxiety, and PTSD symptoms in a sample of 13 people affected by Hurricane Harvey that happened in Houston, TX, August 2017. Brain imaging, specifically resting state functional connectivity of the amygdala was also studied before and after the PT performances. Both anxiety (p = .001, Cohen’s d = –1.25) and PTSD (p = .002, Cohen’s d = –1.0) symptoms significantly decreased after a series of 4 PT performances from January 2019 – February 2019. Depression reduction was not significant. We performed resting state functional connectivity (RSFC) MRI before and after the series of performances. We used the right and left amygdala as seeds for RSFC analysis and found that the connectivity between the left amygdala and the bilateral supramarginal gyri was increased after PT. The bilateral supramarginal connectivity with the default mode and the saliency networks increased too, which correlated with reduction in anxiety scores. PT may offer a form of intervention for anxiety caused by disasters. An increase in left amygdala/supramarginal gyri connectivity may be the underlying mechanism.
