Abstract
Public health emergencies can trigger posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) in adolescents. However, few studies have explored the distinct and common processes of these outcomes in adolescents from the perspective of social support during public health emergencies, and whether the mechanisms underlying these phenomena are unique or shared remains unclear. This study examined how social support relates to PTSD and PTG, with empathy, positive coping, and negative coping as mediators. A cross-sectional study using self-report questionnaires collected data from 921 Chinese junior middle school students. The results showed that social support was directly negatively associated with PTSD and positively associated with PTG. Social support was negatively associated with PTSD via positive coping styles (PCSs), negative coping styles (NCSs), and through a two-step path from empathy to PCSs. Social support was negatively associated with PTG via NCSs, and positively associated with PTG via empathy, PCSs, and through a two-step path from empathy to PCSs. Findings suggest partly distinct pathways linking social support to PTSD and PTG: empathy was related to PTG but not PTSD, PCSs functioned as a shared pathway, and NCSs showed a double-edged pattern. Parents and teachers should foster adolescents' empathy and PCSs to promote healthy psychological development after public health emergencies.
