The authors thank Jennifer Stevens, Ph.D., for her collaboration and willingness to share her materials and methods (namely, the R code used for the clustering analysis and the anatomical regions of interest). The authors also thank the research team at Tel Aviv Sourasky Medical Center (including Naomi Fine, Nili Green, Mor Halevi, Sheli Luvton, Yael Shavit, Olga Nevenchannaya, Iris Rashap, Efrat Routledge, and Ophir Leshets) for their significant contributions to participant screening, enrollment, and assessments. The authors also extend their gratitude to all the participants of this study, who completed assessments at three different time points after experiencing a traumatic event, thus contributing to scientific research of posttraumatic psychopathology.
