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.

反刍方面在人格特质和抑郁症状之间的复杂中介作用

这项研究调查了沉思的各个方面是否在统计上介导了大五人格特质和抑郁症状之间的关系。在 3043 名 18-60 岁参与者（68.8% 女性）的横断面样本中，将自我报告的人格特征和沉思作为抑郁症状的预测因素进行了调查。多元回归分析调查了哪些人格特征和沉思方面最能解释抑郁症状的差异。结构方程模型用于确定反刍的各个方面是否介导了人格特质和抑郁症状之间的关系。多元回归分析发现，抑郁症状的变异最好用神经质、外向、尽责的人格特质来解释；以及沉思、沉思和反思的两个方面。结构方程模型补充说，神经质、外向性、责任心和开放性对抑郁症状的影响在统计学上是由沉思介导的；神经质、外向性和对抑郁症状的开放性的影响在统计上是由反思介导的。反刍方面在统计上介导了各种人格特质对抑郁症状的影响。这些结果提供了洞察哪些人可能最适合针对抑郁症的反刍治疗。反刍方面在统计上介导了各种人格特质对抑郁症状的影响。这些结果提供了洞察哪些人可能最适合针对抑郁症的反刍治疗。反刍方面在统计上介导了各种人格特质对抑郁症状的影响。这些结果提供了洞察哪些人可能最适合针对抑郁症的反刍治疗。
