| Objective To explore the current situation of mobile phone addiction, anxiety and sleep quality among college students, and to test the mediating role of anxiety. Methods A random sample included 630 four-year undergraduate college students, including the smartphone addiction scale, sleep status self-assessment scale (SRSS) and anxiety self-assessment scale (SAS), and description statistics, correlation analysis, regression analysis, Bootstrap method and other methods. Results The scores of mobile phone addiction, sleep quality and anxiety were (83.94±23.70), (37.44±10.69) and (55.18±7.53) respectively; smartphone addiction scale total score and SAS score were positively correlated with SRSS total score (r value was 0.868~0.977, P<0.01). The withdrawal behavior, prominent behavior, social comfort, APP use and total score and anxiety positively predicted sleep quality of college students (β=0.297~0.450, t=2.823~66.790, P<0.01), positively predicted anxiety (β=0.303, t=45.159, P <0.01), and the mediation effect was 0.09 (95%CI: 0.048~0.124, P<0.01), accounting for 19.50% of the total effect. Conclusion The overall situation of mobile phone addiction and anxiety among college students is above the average level, and the sleep quality is at the average level; cell phone addiction can predict sleep quality either directly or indirectly through anxiety.【Funded by Social Science Foundation of Jilin Province（Project name: test anxiety status and hypnosis intervention study in Jilin Province under the influence of COVID-19, Project No.: 2020B124）】 |
