Abstract Objective To explore the mediating effect of sleep quality on mobile phone dependence and loneliness in university students, so as to provide evidence for prevention and intervention of mobile phone dependence. Methods A survey was conducted from December 2019 and January 2020 among the students of Guangzhou Medical University. The general information questionnaire, mobile phone dependence index scale, UCLA loneliness scale and Pittsburgh sleep quality index scale were used to analyze the mediating effects of sleep quality on mobile phone dependence and loneliness. Results A total of 575 questionnaires were distributed and 573 valid ones were collected, with an efficiency of 99.65%. The detection rate of 115 students with mobile phone dependence was 20.07%, and that of 203 students with sleep quality problems was 35.43%. The students scored ( 48.03±6.07 ) points in loneliness, and 405 of them had high level. Mobile phone dependence was positively correlated with loneliness and sleep quality ( r=0.299, 0.385, both P<0.05 ); loneliness was positively correlated with sleep quality ( r=0.553, P<0.05 ). Mobile phone dependence and sleep quality both could positively predict loneliness, mobile phone dependence could positively predict sleep quality, and sleep quality and gender had a significant interaction effect on loneliness ( all P<0.05 ). The mediating effect value of sleep quality on mobile phone dependence and loneliness was 0.290 ( 95%CI: 0.186-0.400 ) in males and 0.131 ( 95%CI: 0.084-0.187 ) in females. Conclusion Sleep quality has a mediating effect on mobile phone dependence and loneliness among university students. Male students are susceptible to the negative effects of mobile phone dependence.
