| Summary: | Objective: There are many internal and external factors that can affect sleep deterioration. The
adopted model of the relationship between chronotype, stress, life satisfaction and sleep quality
was verified in the study. Material and Methods: In total, 335 healthy university students were
surveyed using the Morningness-Eveningness Questionnaire, Perceived Stress Scale, Satisfaction
with Life Scale and Pittsburgh Sleep Quality Index. The study included two groups: individuals
involved in sport activities (student athletes, n=207) and those who declared (in the short form of
the International Physical Activity Questionnaire) low physical activity level (non-athlete students,
n=128). Results: Student athletes were less stressed (p<0.001) and declared higher life satisfaction
(p<0.001) and sleep quality (p<0.001) compared to non-athletes. Non-athletes tended to identify
the evening hours as their best time for functioning (p<0.001), but the mean results of both groups
oscillated around the so-called intermediate type. Despite the differences in mean values, the model
invariance for both groups was confirmed, which means that the proposed theoretical model applies
equally to student athletes and non-athletes. The path analysis results indicate that chronotype has a
direct negative influence on sleep quality (preferring morning hours results in higher sleep quality).
However, perceived stress partially mediates this relationship (p<0.001). Discussion: Sleep quality
should not be considered without taking into account circadian preferences. Effective coping with
stress may also be a buffer in reducing sleep problems. |
