Abstract
Mobile phone addiction has become a widespread phenomenon in Chinese society, attracting significant social attention. However, there is still limited understanding of complexities and relationships concerning anxiety, depression, self-esteem, and mobile phone addiction (MPA) among college students. To better understand the relationships among depression, anxiety, self-esteem, and mobile phone addiction, the aim of this study was to explore these relationships, analyze the factors influencing mobile phone addiction, and examine the mediating effects of anxiety and self-esteem on the relationship between depression and mobile phone addiction. Data from 2023 were collected, and the SDS depression scale, SAS anxiety scale, mobile phone addiction scale, and Robert self-esteem scale were employed. Pearson correlation analysis and structural equation modeling revealed significant associations between depression, anxiety, self-esteem, and mobile phone addiction. Further analysis indicated that anxiety mediated the relationship between depression and mobile phone addiction, meanwhile, self-esteem mediated the relationship between depression and mobile phone addiction. Self-esteem also mediated the relationship between anxiety and mobile phone addiction. Additionally, anxiety and self-esteem played sequential mediating roles in mobile phone addiction. These findings contribute to a better understanding of the mechanisms underlying the relationship between depression and mobile phone addiction. The discussion provides practical and effective recommendations for the prevention and intervention of mobile phone addiction among college students.
