To explore the characteristics of sleep quality, life events and coping style in college students and analyze the relationship among the 3 variables. Pittsburgh Sleep Quality Index (PSQI), Trait Coping Style Questionnaire (TCSQ), Life Event Scale (LES) and a self-edited questionnaire on the general information were adopted for investigating 838 college students who were selected by stratified random sampling from 7 universities in Guangdong Province. (1) The total score of PSQI and LES were (6.09±2.69) and (17.25±20.57), respectively. (2) The score of negative coping and positive coping were (27.26±6.60) and (32.37±6.54), respectively. There is a pairwise correlation among the total score of PSQI, TCSQ and the score of negative coping (r = .246, .122, .148, P < 0.01). There is a pairwise correlation among the total score of PSQI, the score of negative life events and negative coping (r = .281, .122, .163, P < 0.01). There is a pairwise correlation among the total score of PSQI, the score of negative life events and positive coping (r = .281, -.084, -.079., P < 0.05). (3) The negative coping played a partial intermediary role between negative life stimulation and the total score of PSQI, and the intermediary effect accounted for 7.08% of the total effect. Negative life events not only have a direct role on the sleep quality in the undergraduates, but also indirectly influence it through negative coping.
