Few studies have examined the links between personality variables and sleep and their combined effect on specific real-world outcomes. Participants in this study completed numerous personality, sleep, and performance measures; we examined the associations among these measures. Personality was assessed using the Five-Factor Model. The personality trait of Conscientiousness (especially its facet of Achievement Striving) was a substantial predictor of academic performance. Analyses of the sleep variables revealed three distinct constructs: quantity, quality, and schedule. Sleep quantity showed few interesting correlates. In contrast, sleep quality was associated with greater well-being and improved psychological functioning, whereas sleep schedule (i.e., average rising and retiring times) was significantly related to Conscientiousness, such that conscientious individuals maintain earlier schedules.
