While existing theories suggest a strong link between self-esteem and mobile phone addiction, the underlying mechanism remains unclear. This study aims to examine the relationship between self-esteem and mobile phone addiction in Chinese college students, exploring the chain mediation effects of online upward social comparison and social anxiety.Participants and Methods: A cross-sectional study was conducted using an offline questionnaire survey with 789 Chinese college students, employing convenience sampling in Shaanxi Province, China. Four validated instruments were employed: Self-Esteem Scale, Mobile Phone Addiction Index, Online Upward Social Comparison Scale, and Social Anxiety Scale. Descriptive analysis, correlation analysis, and mediation testing were performed to analyze the data.Results: The results showed that self-esteem influences mobile phone addiction through three pathways: (1) self-esteem → online upward social comparison → mobile phone addiction, with a 95% confidence interval of [− 0.048, − 0.010], indicating a significant mediation effect (effect value = − 0.027, accounting for 14.86% of the total effect); (2) self-esteem → social anxiety → mobile phone addiction, with a 95% confidence interval of [− 0.182, − 0.106], indicating a significant mediation effect (effect value = − 0.143, accounting for 78.57% of the total effect); (3) self-esteem → online upward social comparison → social anxiety → mobile phone addiction, with a 95% confidence interval of [− 0.016, − 0.003], suggesting a significant mediation effect (effect value = − 0.009, accounting for 4.95% of the total effect).Conclusion: These findings indicate that online upward social comparison and social anxiety serially mediate the relationship between self-esteem and mobile phone addiction. The study reveals how self-esteem contributes to mobile phone addiction among college students and provides insights for prevention and intervention strategies.Keywords: self-esteem, online upward social comparison, social anxiety, mobile phone addiction, college students
