The Impact of Internet Usage Time on Adolescents’ Self-Confidence: An Analysis of the Mediating Effect of Perceived Social Support

Abstract

In the digital era, adolescents’ online usage time continues to increase. As a core dimension of their physical and mental health and social development, self-confidence is susceptible to the influence of online behaviour. This study focuses on the association between online usage time and adolescent self-confidence. Employing quantitative research methods, the study collected data on online usage and self-confidence assessments from 527 adolescents aged 10 to 18 across different regions via questionnaire surveys. Statistical analytical methods were employed to explore the specific mechanisms through which internet usage duration influences adolescents’ self-confidence. Findings indicate that moderate internet usage positively influences adolescent self-confidence through avenues such as social expansion and skill acquisition. Conversely, excessive usage may induce self-perception distortions and withdrawal from real-world social interactions, thereby undermining self-confidence. Consequently, this study proposes targeted intervention strategies to guide adolescents towards rational internet usage and promoting the healthy development of self-confidence.
