Along with the development of positive psychology, Chinese and western scholars respectively puts forward the Dual-Factor Model of Mental Health(DFM) and Relationship Model between Psychological Suzhi and Mental Health(RM). The DFM theory attention to the accurate assessment of psychological health states, it insists that mental health should be a complete state, assessments of positive indicators (i.e., subjective well-being) are coupled with traditional negative indicators(i.e., Depression) to comprehensively measure mental health(Keyes & Lopez,2005; Suldo & Shaffer,2008). The RM theory focuses on the relations between root (psychological suzhi) and symptoms (mental health states), it sets forth that individual psychological suzhi plays a crucial role in the occurrence and development of illness or wellness(Zhang, 2012; Wang & Zhang, 2012; Wang, 2013). To test the DFM in Chinese college students and its effectiveness, also promote the integration of the DFM and RM, this study using College Students' Psychological Suzhi scale, General Health Questionnaire-12, Satisfaction with Life Scale, Happiness Scale to survey 666 college students those of come from China's ten provinces universities such as Shandong province. The results indicated as follows: (1) A series of confirmatory factor analyses supported an two-factor model of mental health with measures of anxiety and anxiety defining a illness construct and measures of satisfaction with life and happiness defining a wellness construct, fitting index of two dimensional structure of mental health is better than that of unidimensional structure; ⑵the DFM can be used to successfully classify Chinese college students into complete mental health (31.3%), vulnerable (28.2%), symptomatic but content (14.7%), and troubled (25.8%) four types; (3) the four types of mental health state distribution in gender and family locus is no significant difference(p﹥0.05), but significant differences on the grade distribution (p﹤0.05), and the proportion of troubled type to decreases with the grade going up; ⑷the psychological suzhi total score and it’s each factor score have significant difference in four types of mental health states. The psychological suzhi total score and emotional experience, cognition of self, and self adaptive three factors in complete mental health type are significantly higher than vulnerable, symptomatic but content and troubled types, and in troubled type also significantly lower than vulnerable, symptomatic but content and complete mental health types. ⑸The development function of psychological suzhi to positive mental health indicator compared to the treatment function to negative mental health indicators is more outstanding. To sum up, the results revealed that the DFM are applicable in the Chinese college students and their psychological suzhi, the RM theory and the RM theory has a relation of mutual support.
