Depressed, tension and anger mood in the university student population during COVID-19 Pandemic: association with sleep quality and sleepiness


To verify the association among the mood state variables (total mood, depression, tension, and anger domains), sleep quality and the sleepiness of the university students during the COVID-19 Pandemic.


To estimate whether mood is associated with the sleep quality and sleepiness in the university student during the COVID-19 Pandemic.


Two hundred and four university students of both sexes, with a mean age of 23.72±5.95 years, registered from the 2nd to the 7th period of both shifts (day and night classes) in three health courses of Brazilian private universities were participated of this study. Sleep quality was measured by Pittsburgh Sleep Quality Index (PSQI), sleepiness by Epworth Sleepiness Scale (ESS) and mood state was measured by Brazil Mood Scale (BRAMS) before classes (day = 7h00 and night = 19h00). The Kolmogorov-Smirnov test was applied to verify the normality of the data. Spearman correlation coefficient was used to calculate the correlation between the following variables. The α-level for all analysis was set at 0.05.


The results showed there was a significant positive association among poor sleep quality (PSQI>5) and the total mood state (r=0.53; p<0.01), depression mood domain (r=0.42; p<0.01), tension mood domain (r=0.38; p<0.001), and anger mood domain (r=0.28; p=0.02). In addition, there was a significant association among sleepiness (ESS>9) and the total mood state (r=0.59; p<0.01), depression mood domain (r=0.40; p<0.01), and the anger mood domain (r=0.25; p=0.05). Depressed, high levels of tension and anger mood were associated with poor sleep quality (PSQI>5) and increased sleepiness (ESS>9).


Therefore, university students were poor sleep quality, high levels of sleepiness, depression, tension, and anger mood before classes in the day-night shifts. The sleep quality and the sleepiness presented positive moderate correlation with the total mood state. In addition, the sleep quality and sleepiness presented positive weak correlation with depressed, stress and anger mood domains. In this context, it is important to highlight that it is necessary to improve the quality of sleep, alertness, and mood state of the university students during the COVID-19 pandemic to increase their academic performance and positive mood.
