Previous findings on relationships between inhibition that is a core executive function, and trait rumination have been inconsistent. This inconsistency could be overcome by investigating the association between rumination and the two subcomponents of inhibition: response inhibition and attentional inhibition. This study examined whether and how response inhibition and attentional inhibition were related to rumination as well as worry. University students in Japan (N = 213) conducted the Go/No-Go Task and the Modified Stroop Task. They also completed self-report measures of depression, trait rumination, trait worry, stressors, and aggressive behaviors. Results indicated that response inhibition deficits were positively associated with trait rumination, and this association was mediated by increases in aggressive behaviors and interpersonal stressors. The associations between these variables remained significant even after controlling for depression level. There were no significant direct or indirect associations between attentional inhibition deficits and rumination. These results suggest that response inhibition deficits, among the subcomponents of inhibition, have an indirect positive association with rumination through interpersonal processes. Results also showed nonsignificant differences between rumination and worry in the magnitude of correlation coefficients with the two subcomponents of inhibition. Therefore, it remains unclear whether the positive association with response inhibition is unique to rumination.

先前关于作为核心执行功能的抑制与特征反刍之间关系的研究结果不一致。这种不一致可以通过研究反刍与抑制的两个子成分之间的关​​联来克服：反应抑制和注意力抑制。这项研究检查了反应抑制和注意力抑制是否以及如何与反刍和担忧相关。日本大学生（N = 213) 进行了 Go/No-Go 任务和修改后的 Stroop 任务。他们还完成了抑郁、特质反刍、特质担忧、压力源和攻击性行为的自我报告测量。结果表明，反应抑制缺陷与反刍特质呈正相关，这种关联是由攻击性行为和人际压力源的增加介导的。即使在控制了抑郁水平之后，这些变量之间的关联仍然很显着。注意抑制缺陷和反刍之间没有显着的直接或间接关联。这些结果表明，在抑制的子成分中，反应抑制缺陷与人际交往过程中的反刍具有间接的正相关关系。结果还显示，在与抑制的两个子成分的相关系数大小方面，反刍和担忧之间没有显着差异。因此，尚不清楚与反应抑制的正相关是否是反刍特有的。
