This study investigates whether facets of rumination statistically mediate the relationships between Big Five personality traits and depressive symptoms. Self-reported personality traits and rumination were investigated as predictors of depressive symptoms in a cross-sectional sample of 3043 participants aged 18-60 years (68.8% female). Multiple regression analysis investigated which personality traits and rumination facets best explained variance in depressive symptoms. Structural equation modelling was used to determine whether facets of rumination mediated the relationships between personality traits and depressive symptoms. Multiple regression analysis found that variance in depressive symptoms was best explained by the personality traits neuroticism, extroversion, conscientiousness; and both facets of rumination, brooding and reflection. Structural equation modelling added that the effects of neuroticism, extroversion, conscientiousness and openness on depressive symptoms were statistically mediated by brooding; the effects of neuroticism, extroversion and openness to depressive symptoms were statistically mediated by reflection. Rumination facets statistically mediated the effects of various personality traits on depressive symptoms. These results provide insights into which individuals may be best suited to treatments for depression targeting rumination.
本研究调查了反刍思维的各个方面是否在统计学上中介了五大人格特质与抑郁症状之间的关系。在一项横断面样本中，对 3043 名年龄在 18-60 岁的参与者（女性占 68.8%）的自我报告人格特质和反刍思维进行了调查，以了解其作为抑郁症状的预测因素。多元回归分析调查了哪些人格特质和反刍思维方面最能解释抑郁症状的变化。结构方程模型用于确定反刍思维的各个方面是否在人格特质和抑郁症状之间的关系中起中介作用。多元回归分析发现，抑郁症状的变化最好由神经质、外向性、尽责性和开放性这三个人格特质以及沉思和反省这两个反刍思维方面来解释。结构方程模型进一步表明，神经质、外向性、尽责性和开放性对抑郁症状的影响可以通过沉思来进行统计学上的中介；神经质、外向性和开放性对抑郁症状的影响可以通过反省来进行统计学上的中介。反刍思维方面在各种人格特质对抑郁症状的影响中起到了统计学上的中介作用。这些结果为我们提供了一些见解，即哪些人可能最适合针对反刍思维的抑郁治疗。
