以360名大学生为被试，采用匹兹堡睡眠质量指数量表、领悟社会支持量表、担忧问卷以及状态焦虑量表，考察了担忧、焦虑在社会支持和睡眠质量关系之间的多重中介作用。结果表明，复合式多重中介模型能够较好地解释焦虑和担忧在社会支持与睡眠质量之间所起的中介作用。

In the group of Chinese undergraduate students, the problem of sleep quality was severe. Based on the previous research, social support had protective effect on sleep quality. The more social support individual perceived, the less sleep quality problem occurred. However, the mechanism of social support＇s effect on sleep quality was limited, that few researches explored the mediators between social support and sleep quality. According to Thomsen, Mehlsen, Christensen and Zachariae（2003）, pre-sleep negative emotion and cognitive arousal may influence sleep quality directly, and other external variables such as life events had to affect sleep quality through negative emotion or through cognitive activity caused or aggravated by life events. Anxiety and worry respectively as emotional and cognitive variables were popular among college students. Evidence from previous researches, which referred to the relationship among social support, anxiety, worry and sleep quality, could support that anxiety and worry were both mediators between social support and sleep quality. Multiple mediation model was the mediation model containing two mediators or more, contained three type of parallel multiple mediation model, chain multiple mediation model and composited multiple mediation model. And the present study explored that whether composed multiple mediation model of anxiety and worry could explain the influence of social support on sleep quality. The present study selected 360 undergraduate students （male 103, female 257） and adopted Pittsburgh sleep quality index scale, perceived social support scale, worry domains questionnaire and state anxiety inventory. Pearson correlation and SEM were used to analyze the data. The results were that common method biases could be accepted in this study; and that the correlation among perceived social support, worry, anxiety and sleep quality were all significant; that in the composited model X^ 2 = 155.82, X^ 2/df= 2.69, TLI = .94, CFI ： .95, RMSEA = .069, SRMR = .050, which indicated that composited model indicated good fit; the mediating effect in composited model could explain 92.25% of the total effect of social support on sleep quality; the mediating effect of worry in the relationship between social support and anxiety was. 12; the mediating effect of anxiety in the relationship between worry and sleep quality was. 14. The present study concluded that composited multiple mediation model of worry and anxiety could explained the mechanism of influence of social support on sleep quality appropriately, and that the mediating effect could play at the same time, or in a chain.
