The Relationship between Mobile Phone Addiction and Sleep Quality in College Students: Anxiety as a Mediator

Objective: To investigate the relationships between mobile phone addiction, anxiety, and sleep quality among college students. Methods: A total of 444 undergraduate students were assessed using the Mobile Phone addiction Index, the Self-Rating Anxiety Scale, and the Pittsburgh Sleep Quality Index. Among all distributed questionnaires, 421 were valid, resulting in a valid response rate of 94.8%. Results: (1) Significant positive correlations were found among mobile phone addiction, anxiety, and sleep quality in college students. (2) Anxiety partially mediated the effect of mobile phone addiction on sleep quality, with the mediation effect accounting for 40.5% of the total effect. Conclusion: Mobile phone addiction not only directly impacts sleep quality but also indirectly affects it through anxiety. This study provides a basis for interventions aimed at improving sleep quality in college students, highlighting the need to closely monitor mobile phone usage and implement targeted strategies to alleviate anxiety in this population.
