This study explores relations between measures of individuals’ circadian preferences and the Big Five. To this end, we compared a model of circadian preferences that acknowledges morningness (M) and eveningness (E) as separate dimensions to that of a model that places M and E on a single continuum (M-E). Analyses of 620 correlations from 44 independent samples (N = 16,647) revealed weak to modest relations between both dimensions of circadian preferences and the Big Five personality traits. The strongest observed relation was found between Conscientiousness and M (ρ = .37). In the next step, regression analyses revealed that personality traits accounted for between 10.9% and 16.4% of the variance in circadian preferences. Of all the Big Five dimensions, Conscientiousness exhibited the strongest unique relation with M (β = .32), E (β = −.26), and M-E (β = .32). Extraversion and Openness exhibited moderate unique relations with E (β = .23 and β = .17, respectively), whereas relations with M (β = .00 and β = .04), and M-E (β = −.05 and β = −.06) were relatively weak. Neuroticism exhibited a modest unique and negative relation with M (β = −.16), and Agreeableness was largely unrelated to all circadian preference variables. To determine whether these findings translated into anything of applied significance, we explored relations between circadian preference and academic performance. M and E incremented slightly over the Big Five factors in predicting grade-point average. Theoretical and practical implications of these findings are discussed.
