Abstract:Combining the theory and method of subjective and psychological well- being, this paper made a case study on undergraduates of different levels and majors in 6 universities in Wuhan so as to probe into the nature and constitution of well- being and consequently provide suggestions based on an overview of the well- being of undergraduates. The results showed that the subjective and psychological well- being of undergraduates was relatively in a low level, and the negative effect of subject well- being is significantly negative correlated with psychological well- being. Data analysis also demonstrated that these loadings of the higher order factor structure did not vary according to gender, grade or major. Further, suggestions were made to improve the level of well- being, namely helping undergraduates establish the correct values and reasonable life goals; strengthening the education of frustration to encourage psychological adjustment; providing guidance for students to establish harmonious interpersonal relationship; reinforcing the campus cultural construction and improving the comprehensive quality and the sensitivity of the positive emotions experience of college students.
