In light of the global crisis created by the outbreak of the coronavirus and the disease it causes, coronavirus disease 2019, the goal of the study was to detect factors that might enhance people's ability to experience positive psychological change during traumatic events. As such, this study examined the relationship between social participation and posttraumatic growth (PTG) during the coronavirus outbreak and tested the mediating role of hope, social support, and cognitive reappraisal in explaining this relationship. The sample consisted of 275 participants (21.8% male, and 78.2% female, with an average age of 33.42, SD = 13.63), subjected to social-distancing regulations during this period. Results demonstrated a serial mediation model in which social participation predicted PTG directly and indirectly through hope (pathways and agency), social support, and cognitive reappraisal. The importance of social participation in nourishing personal resources and practical implications including the need for prevention programs are discussed.
