Circadian preference has been considered related with impulsivity. The purpose of the present study was to evaluate the relationship between circadian typology and impulsivity measured by the Barratt Impulsivity Scale (BIS), sensation-seeking measured by the Sensation Seeking Scale - Form V (SSS-V) and response inhibition elicited by the GO/NO-GO paradigm. A total of 503 Korean healthy college students (288 males and 215 females) completed the Composite Scale of Morningness (CSM) for circadian typology and the BIS and SSS-V for impulsivity and risk taking, respectively. A subset of 142 subjects additionally performed the computerized GO/NO-GO task for motor response inhibition. A significant association was found between the circadian typology of the CSM and impulsivity of the BIS and disinhibition of SSS-V. In addition, there was a difference in trend level between the circadian typology and response inhibition elicited by the GO/NO-GO test. Regarding circadian preference, evening types were significantly associated with higher impulsivity on the BIS, disinhibition on the SSS-V and lower rate of successful inhibition on the GO/NO-GO task compared to morning types. The present results showed significant relationships between circadian preference and impulsivity and sensation-seeking personality traits. In particular, our findings suggest that high impulsivity, disinhibition and impaired response inhibition are more related to evening types. Circadian preference might be associated with psychiatric problems interacting with some aspects of personality traits such as inhibitory control.
昼夜偏好被认为与冲动性有关。本研究的目的是评估昼夜类型与通过巴拉特冲动性量表（BIS）测量的冲动性、通过感觉寻求量表 - 第五版（SSS-V）测量的感觉寻求以及由GO/NO-GO范式引发的反应抑制之间的关系。共有503名韩国健康大学生（288名男性和215名女性）分别完成了用于昼夜类型的晨型综合量表（CSM）以及用于冲动性和冒险行为的BIS和SSS-V。142名受试者的一个子集还进行了用于运动反应抑制的计算机化GO/NO-GO任务。发现CSM的昼夜类型与BIS的冲动性和SSS-V的去抑制之间存在显著关联。此外，昼夜类型与GO/NO-GO测试引发的反应抑制之间在趋势水平上存在差异。关于昼夜偏好，与晨型相比，夜型在BIS上的冲动性更高、在SSS-V上的去抑制更强，并且在GO/NO-GO任务上的成功抑制率更低。目前的结果表明昼夜偏好与冲动性和感觉寻求人格特质之间存在显著关系。特别是，我们的研究结果表明，高冲动性、去抑制和反应抑制受损与夜型更相关。昼夜偏好可能与精神问题有关，这些问题与诸如抑制控制等人格特质的某些方面相互作用。
