Abstract: Objective To understand the relationship among the mental health level, academic tasks, and social support of medical postgraduates, and provide an effective basis for conducting targeted mental health education interventions.Methods Self-assessment scale (SCL-90) and Occupational Stress Scale(OSI-R) were used to evaluate 778 graduate students in a well-known university in the west of China.Results The detection rate of medical postgraduates' psychological problems was 36.9%(287/778). The SCL-90 overall score were significantly higher than the national youth norms(1.57±0.55 vs 1.44±0.43); each factor of SCL-90 was significantly positively related to overweight tasks(r=0.127), and significantly negatively related to social support(r=-0.228);the overall scores of the SCL-90 factors in the group of the task overload reorganization were higher than those in the normal load group (1.61±0.59 vs 1.51±0.50),and high social support group were significantly lower than the general social support group(1.51±0.49 vs 1.73±0.67).Conclusions The mental health level of medical postgraduates is worse than that of normal young people. The heavier academic load and the lack of social support lead to the worse mental health level. We can improve the mental health of medical postgraduates by building a good social support system.
