The results showed that (1) 7.06 % of university student volunteers had PTSD symptoms to a certain extent, and 2.88 % had obvious PTSD symptoms; (2) PTSD level of university student volunteers was significantly positively correlated with negative coping style, and significantly negatively correlated with social support and positive coping style; on the contrary, the PTG level is significantly positively correlated with social support and positive coping styles. (3) Positive coping style plays a partial mediating role in the influence of social support on PTG; in the influence of social support on PTSD, the mediating effect of positive or negative coping style was not significant. These results show that in the prevention and control of the coronavirus, the positive coping style and social support of university student volunteers can positively predict their PTG level, while the negative coping style can positively predict their PTSD level. Among them, a positive coping style plays a partial mediating role in the influence of social support on the PTG level.
