The Effects of Sleep Quality on the Course Success Levels of the Students of Music Department “Sleep Hygiene for Musical Memory” - Abstract
Study objective: Sleep disturbances that are thought to be related to bad sleep hygiene are especially high among students of university and higher education institutions. In this study, we aimed at identifying the relationship between the subjective sleep quality and academic performance levels of students of music department.
Methods: A total of 132 volunteer students participated in the study [M/F, 70/62; Mean age ( ±SD), 23.5 ± 3.2 years]. Sleep quality was evaluated with Pittsburgh Sleep Quality Index (PSQI). Mean course success of students was evaluated by their academic transcripts. On a scoring system of 5, a grade point average (GPA) of (mean ± SS): 2.3 ± 0.5 or above was defined as academic success. The GPAs of students with good and poor sleep qualities were compared, while comparing the sleep qualities of students who succeeded and failed academically.
Results: Of the 132 volunteers, 44 (33.3%) had good sleep quality, 88 (66.6%) had poor sleep quality. The students with good sleep quality (n=44) had higher GPA (GPA: 2.9 ± 0.7) (p=0.007). Among the students who had academic failure (GPA: 2.2 ± 0.5) (n=31) 90.3% had bad sleep quality. Of the students with good academic performance (GPA: 2.4 ± 0.4) (n=101), 59.4% had bad sleep quality (p=0,003). Academic failure associated with poor sleep quality was 6.38 higher when compared to academic failure associated with good sleep quality (Odds Ratio= 6.378, 95% CI= 1.818-22.376).
Conclusion: Among the students of Music Department, those who failed academically had significantly low subjective sleep quality. We think that, by providing training on sleep hygiene and information on sleep health, sleep quality of this student group can be improved and associated academic performance can be increased.
