Research paperGender, negative life events and coping on different stages of depression severity: A cross-sectional study among Chinese university students

- This study investigated the specific effects of gender, negative life events and coping on different stages of depression severity.
- The effects of gender, negative life events and coping varied in different stages of depression severity.
- The effects of life events and coping became insignificant with the increasing severity of depression, whereas the effect of gender remained significant.

BackgroundThe effects of gender, negative life events, and coping on depression have been well-documented. But depression is a heterogeneous syndrome of which the severity ranged from mild depression to major depression. This study aimed to investigate the specific effects of gender, negative life events, and coping on different stages of depression severity.MethodA total of 5989 students (aged 16-25 years, M=20.85, SD=0.58), recruited from six universities in the central region of China using the stratified cluster sampling method, completed Life Events Questionnaire, Coping Response Inventory, and Beck Depression Inventory-Ⅱ.ResultsAmong the participants, 708 (11.8%) students presented different severity levels of depression. Gender, negative life events, positive coping, and negative coping all had significant effects on depression. That is, the possibility of being depressed was significantly higher in female university students, or students who had more negative life events, more negative coping, or positive coping. In terms of the different stages of depression severity, all these factors had significant effects on the stage from non- depression to mild depression; only gender, negative life events and positive coping had significant effects on the stage from mild depression to moderate depression; only gender had a significant effect on the stage from moderate depression to major depression.LimitationsThe causal role of these factors on different stages of depression severity could not be inferred. Moreover, the participants were from a non-clinical population.ConclusionsThe effects of gender, negative life events and coping varied in different stages of depression severity. The effects of life events and coping styles became insignificant with the increasing severity of depression, whereas the effect of gender remained significant. The results could provide guidance for the prevention, intervention, and treatment of depression.
