PEREIRA, Victor Hugo Dias et al. Personality traits and behavioral sleep patterns: differences between men and women. Temas psicol. [online]. 2018, vol.26, n.1, pp.183-198. ISSN 1413-389X.

This study aimed to investigate the behavioral effects of sleep on the personality traits of young adults. The sample consisted of 114 volunteers with ages between 18 and 40. The subjects were characterized into three groups according to Horne and Östberg (1975): Moderately Morning (n = 23); intermediary (n = 52) and Moderately Evening (n = 39). The Horne and Östberg Morningness and Eveningness questionnaire and the Big Five Personality Inventory were used for data collection. MANOVA showed a significant difference between the chronotype and personality traits [λ = 0.78; F(10.198) = 2.52; p < .05; η2 = 0.11]. The results showed a significant difference on extraversion [F(2.103) = 3.65; p < .05; η2 = 0.06] and kindness traits [F(2.103) = 8.03; p < .05; η2 = 0.14]. The investigation suggests that among these subjects, different personality traits may influence preference for certain periods of the day to carry out daily activities and that there is a relationship with the standard chronotype. Also, the results indicate that men and women have different personality traits when the effects of the sleep behavior are checked.

Keywords : Chronotype; sleep; personality traits.
