Abstract
Daytime sleepiness has great medical and social significance and depends on a variety of internal and external factors. The disadvantage of existing modern questionnaire methods is that they do not include many clinical manifestations of somnolence.
The purpose of the study was creation and testing of an original scale for assessing daily sleepiness (Clinical Sleepiness Scale — СSS) using a wider range of clinical manifestations.
Material and methods. 28 clinical questions were included in the questionnaire, assessing the severity of the physical and mental manifestations of daytime sleepiness. The CSS was approbated on 72 healthy students of a medical university (average age — 22 years). The results were compared with the Epworth sleepiness scale e and Insomnia severity index.
Results. It is shown that CSS has a high degree of coherence. The Alpha-Cronbach correlation coefficient was 0,86, the standardized Alpha coefficient was 0,79. More pronounced daytime sleepiness in CSS was observed in students with reduced quality of sleep. The Epworth scale correlated with CSS (+0,488, p < 0,001), and could not reliably distinguish between different levels of sleepiness in students with different sleep quality, whereas CSS significantly distinguished the severity of sleepiness associated with the quality of night sleep of students.
Conclusion. The created original CSS is a complete questionnaire supplementing the ability to assess daytime sleepiness. CSS compared with the Epworth scale turned out to be a more sensitive indicator of sleepiness.
