Abstract
A correlation of r = -0.18 (p = 0.002) was found between the morningness/eveningness dimension and daytime sleepiness in medical students.
- Daytime sleepiness may be influenced by an individual's circadian rhythm or chronotype.
- Higher coefficients of discrimination for identifying morning versus evening types were found in activities such as resting in the afternoon and reading.
- The study involved 310 medical school students, with an average age of 20.5 years.
- Only the morningness/eveningness dimension was significantly related to levels of daytime sleepiness.
