Cross-sectional study shows rumination mediates the link between childhood trauma and depression severity in adults, suggesting new intervention strategies.
Key Points
The study aims to investigate how rumination mediates the relationship between childhood trauma and major depressive disorder (MDD).
Conducted a cross-sectional study with 94 MDD patients and 91 healthy participants.
Collected sociodemographic data and administered the Beck Depression Inventory, Childhood Trauma Questionnaire-33, and Rumination Scale.
Analyzed data using statistical methods to evaluate direct and indirect effects.
Rumination was significantly predicted by childhood trauma (standardized coefficient=0.44, p<0.001).
Rumination also predicted depression severity (standardized coefficient=0.56, p<0.001).
A significant direct effect was noted between childhood trauma and depression severity (p=0.01, b=0.50).
The mediating model indicated both direct (p=0.011, b=0.24) and indirect effects through rumination (p=0.003, b=0.25).
