Abstract: To explore the correlations between post-traumatic stress response and coping styles and emotion regulation in medical students. Methods 405 college students accepted examinations with Symptom Selfrating Scale of Posttraumatic Stress Response, Emotion Regulation Questionnaire, Coping Styles Questionnaire and Positive and Negative Affects(PANAS). Based on the self-rating scale standard, they were divided into the symptom group and the control group. Results Compared with the control group, the symptom group had more avoidance and suppression in positive emotion, and also had more rumination in negative emotion(P＜0.001 or P＜0.05), while they had less positive emotion than the control group. In the coping styles, the symptom group preferred fancy, selfreproach, keeping out of the way and rationalization. The posttraumatic stress responses were positively correlated with avoidance in positive emotion, rumination in negative emotion, and self-reproach(P＜0.01),　 while negatively correlated with suppression in negative emotion, problem solving and asking for help(P＜ 0.05 or P＜ 0.01). Stepwise linear regression showed that rumination in negative emotion, frequency of experiencing negative emotion and fancy were independently predictive variables of posttraumatic stress responses. ConclusionsThere are close relationships between the posttraumatic stress response and inappropriately coping styles and emotion regulation.
