Abstract

Objective To explore the relationship between stress sources and anxiety symptoms of medical graduate students, as well as the mediating role of negative emotion and the moderating role of social support. Methods A questionnaire survey was conducted among 1 216 medical students of 16 medical colleges in 13 provinces (municipalities directly under the Central Government) by using graduate stressors scale, Hopkins symptom checklist, the positive and negative affect scale and perceived social support scale.Correlation analysis, regression analysis, SPSS-process mediation and adjustment methods were used for data processing. Results (1) The whole average score of stress source was (2.45±0.54), and the scores of anxiety symptoms, negative emotions and social support were (1.68±0.59), (2.26±0.70) and (5.28 ±1.01). (2) There was a positive correlation between stress and anxiety symptoms (r=0.37, P<0.01), and negative emotion (r=0.38, P<0.01) and a negative correlation between stress source and social support (r=-0.20, P<0.01). (3) Negative emotion plays a significant partial mediating role between stressors and anxiety symptoms (indirect effect value=0.24, SE=0.02, 95%CI: 0.20-0.28), accounted for 58.54% of the total effect.(4) Social support moderated the effects of stressors on negative emotion (R2=0.24) and the effects of stressors on anxiety symptoms (R2=0.44). Conclusion Negative emotion plays a partial intermediary role in stress sources and anxiety symptoms, and social support plays a multiple moderating role. Key words: Medical graduate students; Stressors; Negative emotion; Anxiety symptoms; Social support

医学研究生压力源与焦虑症状：负面情绪的中介作用和社会支持的调节作用

目的探讨压力源与医学研究生焦虑症状的关系，以及负性情绪的中介作用和社会支持的调节作用。方法采用研究生压力源量表、霍普金斯症状表、正、负情绪量表和感知社会支持量表对13省(直辖市)16所医学院的1 216名医学生进行问卷调查。采用相关分析、回归分析、spss过程中介和调整等方法对数据进行处理。结果(1)应激源整体平均得分为(2.45±0.54)分，焦虑症状、负性情绪和社会支持得分分别为(1.68±0.59)分、(2.26±0.70)分和(5.28±1.01)分。(2)应激与焦虑症状呈正相关(r=0.37, P<0.01)，与负性情绪呈正相关(r=0.38, P<0.01)，应激源与社会支持呈负相关(r=-0.20, P<0.01)。(3)负性情绪在应激源与焦虑症状之间起着显著的部分中介作用(间接效应值=0.24,SE=0.02, 95%CI: 0.20 ~ 0.28)，占总效应的58.54%。(4)社会支持调节应激源对负性情绪的影响(R2=0.24)，调节应激源对焦虑症状的影响(R2=0.44)。结论负性情绪在应激源和焦虑症状中起部分中介作用，社会支持在应激源和焦虑症状中起多重调节作用。关键词:医学研究生;压力源;负面情绪;焦虑症状;社会支持
