Social support and subjective well-being among postgraduate medical students: the mediating role of anxiety and the moderating role of alcohol and tobacco use
Abstract
Medical students often face pressures from various sources in the course of postgraduate studies, and these factors have a negative impact on their subjective well-being. Previous researches have revealed that social support is a vital factor influencing subjective well-being, but unfortunately the underlying mechanism for this is unclear, especially for postgraduate medical students. The current study has inspected the effects of social support on subjective well-being of postgraduate medical students, the mediating role of anxiety and the moderating role of alcohol and tobacco use in the association between social support and subjective well-being of postgraduate medical students. A sample of 900 postgraduate medical students (Mage = 27.01 years, SD = 3.33) from The Second Affiliated Hospital of Nanchang University completed the Social Support Rating Scale, the Generalized Anxiety Disorder-7, the Tobacco and Alcohol Use Questionnaire and the Subjective Well-Being Scale. Analysis of the structural equation model revealed that anxiety partially mediated the relationship between social support and subjective well-being of postgraduate medical students, while alcohol and tobacco use moderated the relationship between anxiety and subjective well-being of postgraduate medical students. This study revealed how social support act upon subjective well-being of postgraduate medical students. This study provides a theoretical basis for promoting and enhancing the subjective well-being of postgraduate medical students.
