Lack of inhibitory control is present in impulsive and compulsive personality traits. The Go/No-Go task is one of the most effective means to assess response inhibition measured by the ability to appropriately withhold responding to No-Go stimuli. The aim of this work was to study whether differences in performance of Go/No-Go task predicts differences in personality traits related to inhibitory control. For this purpose 63 healthy participants divided into two groups based on the median split of false alarms on the Go/No-Go task completed Barratt Impulsiveness Scale (BIS-11) and the Maudsley Obsessional Compulsive Questionnaire (MOCI). Results showed that participants with high false alarms (H-FA) displayed a high-risk strategy of responding, and higher scores in the MOCI Total and MOCI Checking subscale compared to participants with low false alarms (L-FA). The results show for the first time a relation between the execution of the Go/No-Go task and the MOCI scale. Surprisingly, no relation was found between the Go/No-Go task and the BIS-11 scale. Further studies are needed to define the heterogeneous constructs of compulsivity and impulsivity, and to improve the convergence of the clinical scales and the behavioral measures of these two personality traits.
缺乏抑制控制存在于冲动和强迫人格特质中。Go/No-Go 任务是评估反应抑制的最有效手段之一，通过测量对 No-Go 刺激适当抑制反应的能力来评估。本研究的目的是研究 Go/No-Go 任务的表现差异是否预测与抑制控制相关的人格特质差异。为此，根据 Go/No-Go 任务中的虚报率中位数，将 63 名健康参与者分为两组，完成巴瑞特冲动量表（BIS-11）和莫德斯利强迫症问卷（MOCI）。结果表明，高虚报率（H-FA）参与者表现出高风险的反应策略，且 MOCI 总分和 MOCI 检查子量表的得分高于低虚报率（L-FA）参与者。结果首次表明 Go/No-Go 任务的执行与 MOCI 量表之间存在关系。令人惊讶的是，Go/No-Go 任务与 BIS-11 量表之间没有关系。需要进一步研究来定义强迫和冲动的异质结构，并提高这些两种人格特质的临床量表和行为测量之间的收敛性。
