According to the results of descriptive statistics, sleep quality has six components, and 19 questions have been used to measure each component. Among the components of sleep quality, "mental quality of sleep" with a mean score of 58.14 was the strongest, and "use of sleep drugs" with a mean score of 53 was the weakest component of this item. The mean±SD of descriptive statistics of quarantine scores was estimated at 414.89±54.19. The irritability variable has five dimensions, and the highest mean score belongs to the anxiety/arousal dimension with a mean score of 17.81. On the other hand, the lowest mean score (8.84) belongs to the dissatisfaction and impatience dimension, and finally, the self-esteem variable has three dimensions. Among the dimensions of self-esteem, "social self-esteem (peers)" with a mean weight of 3.06 (based on coefficients) was the strongest, and "general self-esteem" with a mean weight of 3.02 was the weakest dimension of the self-esteem in the subjects.
According to Table 1, it can be observed that the Pearson correlation coefficient shows a positive and significant relationship of about 0.41 between quarantine and total sleep quality (n=377, r=0.405, P<0.01). Therefore, it can be said that a longer time of quarantine leads to the higher total quality of their sleep. Therefore, there is a significant relationship between quarantine and sleep quality. According to Table 2, it can be observed that the Pearson correlation coefficient shows a positive and significant relationship of about 0.33 between quarantine and total irritability (n=377, r=0.334, P<0.01). Therefore, it can be said that the longer time of quarantine results in higher levels of total irritability, and there is a positive and significant relationship between quarantine and all components of irritability, except for dissatisfaction and impatience, as well as incompatibility and perseverance (hostility/haste, lack of focus/impulses to act, and anxiety/arousal) (P<0.05).
Furthermore, the result indicates that a longer time of quarantine in the students leads to higher levels of hostility/haste, lack of focus/impulse, and anxiety/arousal. Among the irritability components, quarantine has the strongest relationship with anxiety/arousal (0.30), and the weakest relationship with dissatisfaction and impatience (0.07).
According to the results of Table 3, it can be noted that the Pearson correlation coefficient shows a positive and significant relationship of about 0.39 between quarantine and total self-esteem (n=377, r=0.391, P<0.01). Therefore, it can be said that a longer time of quarantine results in higher levels of total self-esteem. Moreover, there is a positive and significant relationship between quarantine and all components of self-esteem, except for academic (educational) self-esteem (P<0.05). Accordingly, a longer time of quarantine in the students leads to lower levels of educational self-esteem. Among the components of self-esteem, quarantine has the strongest and weakest relationships with family self-esteem (parents) (0.30) and academic self-esteem (educational) (0.06), respectively.
Discussion
The global pandemic of COVID-19 has affected and paralyzed almost all important economic, political, social, and even military aspects of all countries worldwide. The investigation of the psychological effects of this viral disease on the mental health of people at different levels of society is of great importance. Due to the pathogenicity of the virus, the rate of spread, and the percentage of deaths caused by it, the disease may affect the mental health of people at different levels of society, including patients, health care workers, families, children, students, and psychiatric patients in different ways. Therefore, in the current high-risk situation, identification of the dangers of coronavirus restrictions in this study is in response to the question of whether the quarantine caused by the coronavirus correlated with sleep quality, irritability, and self-esteem of primary school students in District one of Karaj, Iran.
The results of this study were consistent with the findings of studies performed by Ahmadi, Johari, Adnan, Aftab, and Zafar et al. [17]. It was revealed that people who quarantined properly had a higher sleep quality. This can be explained by the fact that breaking the quarantine causes anxiety and worry, and consequently, leads to a decrease in the quality of sleep in people. Therefore, people who observed quarantine properly had a higher quality of sleep. The results of this study were also in line with the findings of a study conducted by Yang, Li, Zhang, Zhang, Cheung, and Xiang [18]; however, the difference is that the aforementioned study was conducted on different groups. In explaining these results, it can be said that quarantine leads to restrictions, such as leaving home; accordingly, children are alone during this period and do not have much fun at home. Sometimes, the only entertainment is playing with smartphones and watching TV, which leads to fatigue and increased impulsivity. In addition, there is a positive and significant relationship between quarantine and all components of self-esteem, except for academic self-esteem, which showed that a longer time of quarantine among students led to higher levels of their academic self-esteem. Among the components of self-esteem, quarantine has the strongest and weakest relationships with family self-esteem (parents) and academic self-esteem (educational), respectively.
Zhou, Snoswell, Harding, Bambling, Edirippulige, and Bai [19] in a study entitled "Understanding Corona Virus 2019 and Corona Virus Disease Based on Evidence" concluded that the complications of Coronavirus 2019 in psychological symptoms are such that all individuals and survivors after illness require specialized counseling in the field of irritability and self-esteem since excessive presence at home leads to self-morbidity and apparent self-criticism that affects self-esteem.
Limitations of the study
Regarding the limitations of this study, one can refer to the lack of similar studies, refusal to transfer information by the respondent, and resistance to answering questions online. Respondents’ patience in answering the questions is one of the other limitations that the indirect researcher faces in such a way that the respondent does not answer some of the questions. Lack of cooperation of individuals, incorrect answers, as well as lack of necessary budget to carry out and advance the research work are other limitations that the researchers face. However, practical suggestions have been provided to reduce the limitations.
Conclusions
The results showed the relationship of quarantine caused by Coronavirus with sleep quality, irritability, and self-esteem of primary school students in District one of Karaj, Iran.
