Abstract
Background Graduate students frequently face life events,many of which may adversely affect their mental well-being.However,the interaction between life events and the development of depression,anxiety,and somatic symptoms remains unclear.Objective To explore the relationship between life events and the development of depressive,anxiety and somatic symptoms in graduate students,thereby informing prevention strategies for these conditions.Methods A sample of 6 722 newly enrolled graduate students at a comprehensive university in Southwest China from September to November 2018 was selected.The assessment was conducted using the Adolescent Self-rating Life Events Checklist(ASLEC),the 7-item Generalized Anxiety Disorder scale-7 item(GAD-7),the Patient Health Questionnaire Depression Scale-9 item(PHQ-9),and the Patient Health Questionnaire-15(PHQ-15).Network analysis was implemented by using the bootnet and qgraph packages in the R software(version 4.2.3),with centrality indices calculated to identify core and bridge symptoms within the network.Results The study encompassed a total of 6 171 graduate students,representing 91.80%of the target population.The prevalence rates of anxiety,depressive,and somatic symptoms among graduate students were 12.59%(777/6 171),16.63%(1 026/6 171),and 27.66%(1 707/6 171),respectively.Network analysis revealed that'academic stress'was the core symptom with the highest strength and expected influence(both values=1.207),while'feeling down,depressed,or hopeless'was the bridge symptom with the highest bridge strength and bridge expected influence(both values=0.454).There was no significant difference in global network strength and edge weight between women and men(P>0.05).Conclusion Academic stress,emerging as the core symptom,assumes a dominant position within the symptom network and exhibits strong interactions with other negative affective states.There was no gender difference in the network structure.关键词
