Although awe has been shown to increase prosocial behavior, there is limited knowledge about the mechanisms underlying this relationship, and about this relationship during unique periods. To bridge these gaps, this study examined the influence of awe on prosocial behaviors, the mediating role of the presence of meaning in life, and the moderating role of perceived social support. Based on longitudinal surveys from 676 Chinese college students we showed that: (1) awe was positively associated with prosocial behavior; (2) the presence of meaning in life mediated this association, and; (3) these associations were moderated by perceived social support. Specifically, the positive relationship between awe and the presence of meaning in life was only significant for college students with low perceived social support; and the positive relationship between the presence of meaning in life and prosocial behavior was stronger for college students with high perceived social support.

The COVID-19 pandemic was an unexpected, long-term negative event. Meaning in life has been linked to better psychological adjustment to such events. The current study uses longitudinal data collected during the COVID-19 pandemic to discover whether perceived social support mediates the relationship between six dimensions of prosocial behavior (Altruistic, Anonymous, Public, Compliant, Emotional, and Dire) and meaning in life. A sample of Chinese college students (N = 514) was tracked at three time points (T1, T2, and T3) during the COVID-19 outbreak. A cross-lagged panel model (CLPM) was used for mediation analysis. The mediation effect was found in all the dimensions of prosocial behavior except for Public prosocial behavior. We also found a longitudinal, bidirectional association between perceived social support and meaning in life. The current study contributes to the growing literature on the significance of prosocial behavior in predicting meaning in life.
