RESUMEN
BACKGROUND: 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. METHOD: 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. RESULTS: 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. CONCLUSIONS: 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.
RESUMEN
Playback Theatre (PT) is an improvisational form of theatre in which a group of actors "play back" real life stories told by audience members. In PT, a conductor elicits moments, feelings and stories from audience members, and conducts mini-interviews with those who volunteer a moment of their lives to be re-enacted or "played" for the audience. A musician plays music according to the theme of each story, and 4-5 actors listen to the interview and perform the story that has just been told. PT has been used in a large number of settings as a tool to share stories in an artistic manner. Despite its similarities to psychodrama, PT does not claim to be a form of therapy. We offered two PT performances to first year medical students at Baylor College of Medicine in Houston, Texas, to bring the students a safe and fun environment, conducive to sharing feelings and moments related to being a medical student. Through the moments and stories shared by students, we conclude that there is an enormous need in this population for opportunities to communicate the many emotions associated with medical school and with healthcare-related personal experiences, such as anxiety, pride, or anger. PT proved a powerful tool to help students communicate.
