Objective: To explore the association between stress, coping style, social support and subjective well-being (SWB) of college Students. Methods: 1773 college students from 8 colleges in Guangzhou were tested with Index of Well-being Questionnaire, College Students’ Stress Scale, Simplified Coping Style Questionnaire(SCSQ) and Social Support Rating Scale (SSRS). And structural equation model (SEM) was built based on the data. Results: SEM revealed ?2/df=2.837, RMSEA=0.032, and indexes of GFI、AGFI、NFI、NNFI、CFI were all above 0.9. Stress and passive coping style had passive effect on SWB (the overall regression weights were -0.377 and -0.130 respectively). Social support and positive coping style had positive effect on SWB (the overall regression weights were 0.286 and 0.277 respectively). Conclusion: Stress, coping style and social support are important forecast variables of SWB.

BACKGROUND: Some scholars thought that social support is one of the key factors in determining self-esteem, and most scholars thought that subjective support is more meaningful than objective support. Yet on the domain of social support, Chinese scholars still put forward a problem about utilizations of social support besides subjective and objective support. However,how is the relationship between self-esteem and social support, especially the utilizations of social support in college students?OBJECTIVE: To probe into relationship between self-esteem and social support of college students and understand self-esteem and social support status of them.DESIGN: Cluster sampling and present situation study based on college students.SETTING: Department of medical psychology and behavior science in medical college of a university.PARTICIPANTS: Totally 154 comprehensive college students in south China were investigated.METHODS: Adopting self-esteem scale(SES) and social support questionnaire(SSQ) to conduct a self-evaluating investigation among 154 students in a comprehensive university in south China.MAIN OUTCOME MEASURES: The scores on SES and SSQ on three dimensions for 154 college students.RESULTS: The boy college students got higher scores on self-esteem than that of girls' ( t = 2. 510, P ＜ 0: 05). Non-only-child college students' total scores and utilizations of social support were significantly higher than only child college students(t= -1.983, P ＜0.05; t= -3.475, P=0.01).The self-esteem was significantly positive correlated with the utilization of social support.CONCLUSION: College students'self-esteem is related to social support.
