Abstract
BACKGROUND/OBJECTIVE: Social media significantly influences adolescents' prosocial behavior. With smartphones becoming ubiquitous, short videos have emerged as the predominant social media format for adolescents. However, the effects of adolescents' engagement with short videos on their prosocial behavior remain uncertain. This study aims to address the problem of how short videos (content and consequences) affect prosocial behavior in adolescents, and simultaneously explores the differences of this effect among individuals with different social value orientations. METHODS: The current study conducted two research laboratory experiments using the between-subject study design of two factors. Study 1 (N=148) reveals that viewing prosocial short videos significantly predicts adolescents' prosocial behavior more so than neutral short videos. The interaction between short video content and social value orientation on prosocial behavior illustrates that the encouraging impact of prosocial content is primarily evident in prosocial individuals, rather than in pro-self individuals. In Study 2 (N=152), we introduce new dimensions by assessing adolescents' response to varying consequences of the same prosocial behavior (ie, reward, punishment) within the short video context. Findings indicate that reward consequences significantly bolster adolescents' prosocial behavior, whereas punitive measures tend to adversely affect it. Furthermore, the interaction between the consequences of prosocial short videos and social value orientation suggests that prosocial individuals exhibit no significant behavioral difference between rewards and punishments; instead, the reward/punishment consequences notably influence the prosocial behavior of pro-self individuals. CONCLUSION: Short videos (content and consequences) and social value orientations interactively influence adolescents' prosocial behaviors. This study underscores the need to recognize individual differences in adolescents' use of short videos and its impact on their prosocial behavior, particularly highlighting the crucial role of their social value orientations. Practically, the research offers valuable insights for parents and professionals seeking to foster adolescents' prosocial behavior.
