Abstract
This study examined the association between prosocial behavior and posttraumatic growth (PTG) among Chinese caregivers of seriously ill patients, focusing on the mediating roles of social support and deliberate rumination. A total of 232 caregivers (79 males, 153 females) completed the Posttraumatic Growth Inventory, Prosocial Tendencies Measure, Social Support Rating Scale, and Event-Related Rumination Inventory. Regression and mediation analyses showed that prosocial behavior was positively related to PTG. Both social support and deliberate rumination significantly mediated this relationship in parallel. These findings indicate that prosocial behavior has a positive effect on PTG among caregivers of seriously ill patients. This direct effect, as well as the mediating roles of social support and deliberate rumination, highlights both social-contextual and cognitive pathways underlying PTG among caregivers.
