Short-video applications use and self-concept clarity among adolescents: The mediating roles of flow and social media self-expansion

Recently, the usage of short-video applications (apps) has become widespread and the potential influence of short-video apps use on individuals has attracted the attention of researchers. However, few studies have explored the influence of short-video apps use on adolescents' self-concept clarity. This study aimed to examine the relationship between short-video apps use and self-concept clarity among adolescents and whether this relationship is mediated by flow and social media self-expansion. A total of 721 Chinese adolescents completed questionnaires on intensity of short-video apps use, flow, social media self-expansion, self-concept clarity, and SNS use intensity. The results revealed that short-video apps use was negatively related to self-concept clarity among adolescents. Flow mediated the association between short-video apps use and self-concept clarity. Moreover, the relationship between short-video apps use and self-concept clarity was sequentially mediated by flow and social media self-expansion. These findings offer new insights into our understanding of adolescents' self-development in the context of digital media and provide implications for fostering healthier online experiences among adolescents.
