The present study evaluated the frequency and severity of stress symptoms and associated demographic factors in children and adolescents aged 4 - 18 years during the COVID-19 outbreak in Shiraz, Iran. According to the results, children were worried about this unknown disease and the probability of their parents’ death resulting from the disease (
17).
In this study, all the 26 items of the questionnaire were reported as symptoms of stress by children and adolescents. The symptoms of stress were classified into cognitive-emotional and physical symptoms. Our results revealed that participants had experienced cognitive-emotional symptoms more than physical ones. More than 50% of participants reported symptoms, including worrying, anger, and bad temper, and more than 35% of them reported sadness and no clear thoughts. These results are consistent with the findings of an Iranian study in terms of reporting worrying and sadness as the most common cognitive-emotional symptoms of stress in children (
13). In addition, the Center for Diseases Control and Prevention (CDC) stated that children show symptoms such as excessive worrying or sadness, crying or irritation, irritability etc., during the COVID-19 outbreak (
18).
The present study showed that the least symptoms that pediatric cases reported were related to physical ones, including cold feeling, chilling, fast heart beating, face flushing, sweating, hunger, etc. On the contrary, a study showed that physical symptoms such as headache and stomach-ache were the most common symptoms of stress in children (
19). Another study also approved the physical symptoms of stress (
20). These controversies can be related to the unique situation of the COVID-19 outbreak because this unknown disease with high transmissibility and mortality has caused a great deal of panic and fear in the communities. In our study, weakness, unwell feeling, skin rash, nausea and vomiting, and stomach-ache were identified as the most common physical symptoms of stress. Since stress can be the main factor causing many psychosomatic diseases, especially during the pandemic, the parents and caregivers are suggested to pay more attention to children's mental health.
Frequency and severity of physical symptoms of stress had a significant relationship with the age group, such that older children showed more physical symptoms of stress. As other studies showed that children are aware of their surroundings even from two years (
9), it seems essential that parents inform their children based on their age. This effective relationship can benefit children and even their families to improve their psychological well-being during the outbreak.
A previous study showed that children aged 4 - 7 years have magical thinking so that their thoughts and beliefs can cause an external event such as a disease (
21). Our findings revealed that participants aged 4 - 7 years reported feeling weird more than other age groups. Thus, adults should help the children to refrain from blaming themselves during illness or not consider their illness as a punishment for their destructive behaviors. On the other hand, in the COVID-19 outbreak, the parents have an essential role in protecting children from stress and preventing negative emotions.
Quarantine and its psychological effects are other problems resulting from COVID-19. Parents' involvement with the consequences of COVID-19 may cause them to ignore to respond to their children's distress timely. On the other hand, children may show challenging external behaviors such as fight instead of routine responses to stress (
22). Our results showed that children who spent more time at home quarantine reported more cognitive-emotional symptoms of stress, including bad temper, sadness, and a tendency to fight. In this regard, the World Health Organization (WHO) announced that parents and child caregivers should help children find positive methods for expressing their feelings of fear and sadness during the COVID-19 outbreak, and they should keep their children close to themselves (
23).
As our results showed, the children whose mothers worked in a hospital or university-related centers reported more stress-related cognitive-emotional symptoms, including no clear thoughts. Therefore, it is recommended that parents involve their children in creative activities such as playing and drawing during the quarantine period and encourage them to state their thoughts in a safe and supportive environment.
Moreover, due to quarantine, it is suggested that parents use mental health improvement strategies, including spending time with children, answering questions, and sharing facts about COVID-19 in a way that they can understand, guiding children into regular activity schedule, and even consulting with a pediatric psychologist at the time of severe symptoms of stress.
5.1. Strengths and Limitations
This study had some limitations. We used the online sampling strategy because of the limited face-to-face contact and time sensitivity of the COVID-19 outbreak. Therefore, the study population may not reflect the actual pattern of the general population. Furthermore, self-reported symptoms of stress may not always be aligned with assessments evaluated by mental health experts. Likewise, respondents might have provided socially desirable responses in terms of satisfaction with the health information received.
Regardless of the limitations mentioned above, this study provides invaluable information on symptoms of stress among children in the first four months after the outbreak of COVID-19. To the best of our knowledge, few studies have used an online questionnaire to examine both physical and psychological symptoms of stress in children and adolescents. Given the home quarantine situation, it was impossible to access people. Also, paper questionnaires could increase the risk of virus transmission and more samples attrition. Therefore, online questionnaires could help to achieve better results. Our study was conducted with an almost acceptable response rate.
5.2. Conclusions
During the first four months of the COVID-19 outbreak, most of the respondents reported the degree of stress as low-to-moderate, and almost 25% of participants reported moderate-to-severe stress. The most common symptoms of stress in children were worrying, anger, and weakness. Also, older children, those being the first child, and children living with both parents were more exposed to stress. Therefore, these items should be included in the training provided to the health care team. Besides, psychological experts should formulate evidence-based guidelines and cost-effective psychological plans to cope with COVID-19 outbreak-related symptoms of stress in children and adolescents. This study confirmed the presence of stress symptoms in children aged 4-18 years during the COVID-19 outbreak. Therefore, it is recommended to conduct further longitudinal studies on the impact of long-term consequences of stress caused by the COVID-19 pandemic. Future studies can help to design the management and reduction interventions of stress to promote the health of this age group.
