摘要

According to the 53nd Statistical Report on the Development of China’s Internet, the total number of short video users in China has reached 1.053 billion. The uneven quality of short video content, coupled with excessive information, can significantly influence adolescents' self-perception and evaluation of their abilities. This study aims to explore the relationship between adolescent short video usage and core self-evaluation, while examining the mediating roles of information overload and maladaptive internet cognition. The goal is to address the limitations of previous research and provide more robust evidence to support adolescents' physical and mental health. In November 2023, a survey was conducted on 1519 adolescents from two universities in Henan Province, China, using the Chinese version of Short Video Use Intensity Scale, Online Maladaptive Cognitions Scale, Information Overload Scale, and Core Self Evaluation Scale. The collected data were analyzed using SPSS 19.0 for descriptive statistics, independent samples t-tests, ANOVA, and Pearson correlation analysis. Subsequently, AMOS 24.0 was employed to test the mediating effects among the variables and to construct a chain mediation model. The results of this study indicate that adolescents' short video usage does not directly affect core self-evaluation (β = -0.054, P > 0.05). The indirect effect of short video usage → information overload → core self-evaluation is 0.077, accounting for 29.30% of the total effect, with a 95% CI [0.050, 0.112]. The indirect effect of short video usage → maladaptive cognition in internet use → core self-evaluation is 0.208, accounting for 78.80% of the total effect, with a 95% CI [0.157, 0.267]. The indirect effect of short video usage → information overload → maladaptive cognition in internet use → core self-evaluation is 0.025, accounting for 9.30% of the total effect, with a 95% CI [0.014, 0.039]. In summary, the chain mediation effect of information overload and maladaptive cognition in internet use between short video usage and core self-evaluation is established, with a total effect size of 0.264. This study demonstrates that while short video usage does not directly impact adolescents' core self-evaluation, it exerts an indirect influence through information overload and maladaptive internet cognition. Specifically, excessive short video consumption leads to information overload, which then fosters maladaptive cognitive patterns, ultimately negatively affecting core self-evaluation. These findings highlight the importance of managing digital consumption and addressing maladaptive cognition to safeguard adolescents' psychological well-being.
