Objective: The aim of this study is to explore the association of mobile phone addiction and positive and negative emotion, and the mediation of sleep quality on this association. Methods: A total of 600 subjects ranging from freshman to senior students in Guangxi University were enrolled in this study from September 2021 to December 2021.Smartphone Addiction Scale(SAS-SV), Positive and Negative Affect Schedule(PANAS) and Athens Insomnia Scale(AIS) were applied to evaluate the condition of mobile phone addiction, positive and negative emotion, and sleep quality. Mediation analysis was performed using an indirect effects mediation model consisting of two linear regression models. Results: Among 600 college students, the rate of mobile phone addiction was 32.2%,and rate of suspected insomnia and insomnia were 21.2% and 19.0%,respectively. Mobile phone addiction was related to gender,professional preference and usual performance(P<0.05). Correlation analysis showed that mobile phone addiction was negatively associated with positive emotion, while positively associated with negative emotion and sleep quality(P<0.05). Mediation analysis revealed mobile phone addiction have a negative effect on positive emotion(β=-0.312,95%CI -0.375~-0.249,P<0.05),and positive effect on negative emotion(β=0.226,95%CI 0.155~0.298,P<0.05). The mediation of sleep quality was significantly in the association of mobile phone addiction and positive and negative emotion. And then the percentage of sleep quality effect contributed by mediation effect were 15.7% and 19.6%,respectively. Conclusion: Sleep quality partially mediated the association between mobile phone addiction and positive and negative emotion, especially in the part of negative emotion. The relevant departments of schools need to conduct health education activities to enhance college students' awareness of healthy sleep, enable them to maintain positive and optimistic emotions and good mobile phone usage habits, and reduce the impact of mobile phone addiction on learning and life. |
