A replication and extension of the prosocial effect of online social interactions among Chinese and American emerging adults

The recent global crisis has had a profound and widespread impact on humanity, eliciting a heightened appreciation for the importance of prosociality. In response, interdisciplinary scholars have called for further research to investigate strategies for cultivating kindness, generosity, and cooperation. To answer this call, we conducted a study examining the potential prosocial impact of online social interactions (OSIs) in two distinct cultures. Through a survey of 644 emerging adults from China and the United States, we found that OSIs positively led to prosocial tendencies in both samples, with social connectedness and trust serving as significant mediating factors. Nevertheless, among the American sample, trust can serve as the sole mediator linking OSIs and prosocial tendencies. Conversely, among the Chinese sample, the development of prosociality stemming from OSIs requires the intervening facilitation of social connectedness. This divergence may speak to cultural research regarding the essential role of interpersonal relationships in fostering trust and prosociality in collectivist societies. This study contributes to prosociality scholarship by highlighting the role of OSIs as a crucial enhancer across two distinct cultures, clarifying the underlying mechanisms, and identifying cultural differences in the process of prosocial development. The results have implications for both prosocial theory and practice.
