Abstract:
Depression Anxiety Stress Scales （DASS），Pittsburgh Sleep Quality Index （PSQI）and General Self-Efficacy Scale
（GSES）are used to investigate 575 higher vocational college students.The relationships between their negative emotion，sleep quality and self-efficacy were analyzed by binary Logistic regression analysis method. The results show that the detectable rate of depression，anxiety and stress of higher vocational college students was 25.6%，48%，24.5%，respectively. The prevalence of sleeping problems in them was 29.7% and self-efficacy was（24.07依5.25）which was below that of the national adults（t=-20.826，孕<0.001）. Depression， anxiety and stress had significant positive effects on sleep quality （孕<0.05）；Sleep quality negatively predicted self-efficacy （孕<0.05）；Depression，anxiety and stress indirectly influenced the self-efficacy through the sleep quality（孕<0.01）. A conclusion can be drawn that negative sleep quality and emotion had impacts on the self-efficacy in vocational college students，and the sleep quality played a partly mediating role between negative emotion and self-efficacy in vocational college students.

Key words: vocational college students, negative emotion, sleep quality, self-efficacy
