Objective To investigate peritraumatic dissociative experiences and peritraumatic distress after traumatic events, and explore the relationship between peritraumatic dissociative experiences and peritraumatic distress. Methods Peritraumatic dissociative experiences questionnaire (PDEQ) and peritraumatic distress inventory（PDI） were employed to evaluate peritraumatic dissociative experiences and peritraumatic distress, respectively in 60 people who had experienced traffic accidents, industrial accidents or incidents of violence. The gender distribution of different PDI/PDEQ scores was determined, and the relationship between peritraumatic dissociative experiences and peritraumatic distress was explored. Results The median PDI score and PDEQ score were 0.92 and 1.00, respectively, and PDEQ was significantly correlated with PDI （r=0.823, P＜0.001). Those without serious peritraumatic dissociative experiences maintained a low level of peritraumatic distress, and 71.43% and 28.57% of people with serious peritraumatic dissociative experiences had serious and medium peritraumatic distress, respectively. Conclusion Peritraumatic psychological health is an important issue, and it is necessary to conduct psychological evaluation with PDI and PDEQ within a week after traumatic events. Peritraumatic dissociative experiences tend to be caused by serious peritraumatic distress or may be an epiphenomenon of serous peritraumatic distress.
