Abstract
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.
