In the present study, the relationship between personality dimensions and Circadian Preference was evaluated using a structural equation modeling approach. Participants (N=390; 53.8% female, mean age: 26.8 ± 8.1 yrs) completed measures of Circadian Preference, Impulsivity, Sensation Seeking, and the Big Five factors. A mediation structural equation model assessed the direct and indirect effects of the Big Five factors on Circadian Preference. The results showed that Impulsivity and Sensation Seeking were significantly associated with Eveningness, whereas no significant direct effects of the Big Five traits were detected once the effects of Impulsivity and Sensation Seeking were taken into account.
在本研究中，采用结构方程建模方法评估了人格维度与昼夜节律偏好之间的关系。参与者（N=390；女性占 53.8%，平均年龄：26.8±8.1 岁）完成了昼夜节律偏好、冲动性、感觉寻求和大五因素的测量。一个中介结构方程模型评估了大五因素对昼夜节律偏好的直接和间接影响。结果表明，冲动性和感觉寻求与夜间型显著相关，而在考虑到冲动性和感觉寻求的影响后，大五特质没有检测到显著的直接影响。
