摘要

Co-rumination involves excessive discussion about personal problems, which can either exacerbate depressive symptoms or enhance social support through improved friendship quality. current study aims to discover the role of perceived social support as a mediator in the relationship between co-rumination and depression within a clinical population. This study is cross-sectional and involved 260 participants (73% female, aged 18–30) diagnosed with MDD according to DSM-5 criteria. Participants completed the Beck Depression Inventory-II (BDI-II), Co-Rumination Questionnaire (CRQ), and Multidimensional Scale of Perceived Social Support (MSPSS). Structural Equation Modeling (SEM) was employed to test the hypothesized mediational model. Model fit was assessed using multiple indices, and bootstrapping with 5000 samples was used to test the significance of indirect effects. The structural equation model demonstrated excellent fit indices (CMIN/DF = 1.683, RMSEA = 0.052, CFI = 0.982, TLI = 0.962, GFI = 0.969, AGFI = 0.939). Results revealed that perceived social support fully mediated the relationship between co-rumination and depression. While co-rumination showed no significant direct relationship with depression (β = 0.170, p > 0.05), it had a significant positive association with perceived social support (β = 0.580, p < 0.001), which in turn was negatively associated with depression (β = -0.402, p < 0.05). The indirect effect through social support was significant (β = -0.233, p < 0.05). The results, highlight the importance of social support in addressing depressive symptoms, the findings have implications for psychologists in understanding and addressing depression in clinical populations.
