Abstract: Objective:To study the social support and the mental health status on medical staff from different level hospitals,and analyze the relationshipbetween the social support and mental health status.Methods:Five hundred medical workers were surveyed with the Social Support Rating Sheet (SRRS) and Symptom Checklist (SCL-90) questionnaire.Results:There were significantly differences about social supports in various dimensions between medical staffs with different ages,marital status and job title in hospital.(P＜0.05),but no differences between medical staffs with different gender and education (P＞0.05).There were significantly differences about the SRRS and other factors scores between the hospital staffs from different level hospitals(P＜0.01).The SRSS total score,objective support score,and the utilization of supports had negatively correlated with the SCL-90 total score and other factors score(P＜0.01).Conclusions:The impacts of social support on mental health should be given full consideration when we make psychological counseling programs for medical staff from different level hospitals.
