“…Evidence from other studies provides some clues to the mechanism underlying this pattern of associations. Regarding circadian preferences, it is intriguing that those who score high on conscientiousness, and to a lesser extent high agreeableness, are more likely to be morning type (38) and have a diurnal preference (39, 40). Furthermore, students with lower conscientiousness reported not getting enough sleep (41) and worse sleep quality (42).…”

Objective A nighttime dip in blood pressure is associated with decreased risk of cardiovascular morbidity and mortality. We examined whether personality traits predict nighttime dipping blood pressure. Methods A community-based sample of 2,848 adults from Sardinia (Italy) completed the Revised NEO Personality Inventory and 7.34-years later (SD=0.87) were examined with 24-hour ambulatory blood pressure monitoring. The primary analyses examined the associations of personality traits with continuous and categorical measures of mean arterial, systolic and diastolic blood pressure nighttime dipping. Results Agreeableness and conscientiousness were associated with more nocturnal blood pressure dipping (β = .05, p=.025 and β = .07, p<.001, respectively) and lower systolic blood pressure at night (β = -.045, p=.018 and β = -.032; p=.072, respectively). Non-dippers were particularly more impulsive (p=.009), less trusting (p=.004), and less self-disciplined (p=.001), but there was no significant association between nocturnal dipping blood pressure and trait anxiety (p=.78) or depression (p=.59). The associations were stronger when comparing extreme dippers (nighttime drop ≥ 20%) to reverse dippers (nighttime increase in blood pressure). Indeed, scoring 1 SD higher on conscientiousness was associated with about 40% reduced risk of reverse dipping (OR = 1.43, CI = 1.08-1.91). Conclusions We found evidence that reduced nighttime blood pressure dipping is associated with antagonism and impulsivity related traits but not with measures of emotional vulnerability. The strongest associations were found with conscientiousness, a trait that may have broad impact on cardiovascular health.

“…Yet, when using the FFM personality traits with age and gender to predict morningness-eveningness in a multiple regression model, found that only three personality traits-Openness, Conscientiousness, and Extraversion-remained significant predictors of morningnesseveningness. Thus, based on this and other studies that have demonstrated the importance of gender, age, and education level in chronotype (e.g., Barclay, Eley, Buysse, Archer, & Gregory, 2010;Paine, Gander, & Travier, 2006;Walker, Kribs, Christopher, Shewach, & Wieth, 2014), and personality traits (e.g., McCrae et al, 2004;Schmitt, Realo, Voracek, & Allik, 2008), we will adjust our analyses for these demographic variables. Given that time of year has a significant effect on the epidemiological variation in sleep duration (Allebrandt et al, 2014;Randler & Rahafar, 2017), we will also control for the effect of seasonal variation on chronotype.…”

Introduction: Diurnal preferences have been linked to personality but often with mixed results. The present study examines the relationships between sleep timing (chronotype), diurnal preferences and the Five-Factor Model of personality traits at the phenotypic and genetic level. Methods: Self-and informant-reports of the NEO Personality Inventory-3, self-reports of the Munich Chronotype Questionnaire, and DNA samples were available for 2,515 Estonian adults (Mage = 45.76 years; 59% females). Genetic correlations were obtained through summary statistics of genome-wide association studies.Results: Results showed that higher Conscientiousness and lower Openness to Experience were significant predictors of earlier chronotype. At the level of facets, we found that more straightforward (A2) and excitement-seeking (E5), yet less self-disciplined (C5) people were more likely to have later chronotypes. The nuance-level Polypersonality score was correlated with chronotype at r = .28 (p < .001). Conscientiousness and Openness were genetically related with diurnal preferences. The polygenic score for morningnesseveningness significantly predicted the Polypersonality score. Conclusion:Phenotypic measures of chronotype and personality showed significant associations at all three of levels of the personality hierarchy. Our findings indicate that the relationship between personality and morningness-eveningness is partly due to genetic factors. Future studies are necessary to further refine the relationship.

“…However, it is difficult for most persons to live a daily social life by following their chronotype due to work or school. The factors of WSD other than chronotype should be specified to prevent sleep debt because the chronotype are reported to be influenced by genetic factors ( 5 ) as well as age, and personality ( 9 ).…”

The present study investigates the factors of “Weekday sleep debt (WSD)” by comparing activity data collected from persons with and without WSD. Since it has been reported that the amount of sleep debt as well the difference between the social clock and the biological clock is associated with WSD, specifying the factors of WSD other than chronotype may contribute to sleep debt prevention. We recruited 324 healthy male employees working at the same company and collected their 1-week wrist actigraphy data and answers to questionnaires. Because 106 participants were excluded due to measurement failure of the actigraphy data, the remaining 218 participants were included in the analysis. All participants were classified into WSD or non-WSD groups, in which persons had WDS if the difference between their weekend sleep duration and the mean weekday sleep duration was more than 120 min. We evaluated multiple measurements derived from the collected actigraphy data and trained a classifier that predicts the presence of WSD using these measurements. A support vector machine (SVM) was adopted as the classifier. In addition, to evaluate the contribution of each indicator to WSD, permutation feature importance was calculated based on the trained classifier. Our analysis results showed significant importance of the following three out of the tested 32 factors: (1) WSD was significantly related to persons with evening tendency. (2) Daily activity rhythms and sleep were less stable in the WSD group than in the non-WSD group. (3) A specific day of the week had the highest importance in our data, suggesting that work habit contributes to WSD. These findings indicate some WSD factors: evening chronotype, instability of the daily activity rhythm, and differences in work habits on the specific day of the week. Thus, it is necessary to evaluate the rhythms of diurnal activities as well as sleep conditions to identify the WSD factors. In particular, the diurnal activity rhythm influences WSD. It is suggested that proper management of activity rhythm may contribute to the prevention of sleep debt.
