Associations Between Morningness-Eveningness and Sleep Quality Among Female Dormitory Residents

Results: Over 60% of the students were categorized as poor-quality sleepers by the PSQI, 69.2%, 27.5%, and 3.2% of the subjects were intermediate, evening, and morning types, respectively. There was a significant negative correlation between MEQ and PSQI scores and its dimensions such as subjective sleep quality, sleep latency, sleep duration, and sleep efficiency (P < 0.05); while there were no significant differences between sleep disturbances, daytime dysfunction, use of sleep medication, and MEQ scores. Conclusions: The results showed that the quality of evening type sleep was worse than that of the morning type.
