Background Coronavirus disease 2019 (COVID-19) has a significant impact on children, adolescents, and their families. So, the purpose of this study is to investigate the prevalence of children’s psychological problems during the COVID-19 pandemic and their association of COVID-19 infection in children and their risk factors. A cross-sectional study was conducted on 148 children aged 6–12 years old categorized into 2 groups based on COVID-19 infection history. Participants were assessed by the Socioeconomic Scale and the Checklist for Children’s Behavior (CBCL). Results Children who had COVID-19 had a high percentage of problems regarding family, school, social, financial, and parent problems due to the COVID-19 pandemic. Regarding CBCL, children who had COVID-19 infection had a higher percentage of clinical rating than the other group regarding withdrawal (11.1% vs. 8.9%), anxious/depressed (33.3% vs. 25%), somatic (11.1% vs. 10.7%), internalizing (61.1% vs. 48.2%), externalizing (38.9% vs. 35.7%), and total problems (50% vs. 44.6%). Family history of psychiatric disorder and the presence of three or more offspring were at high risk for internalizing problems, while those with school problems during pandemic were more vulnerable for internalizing and total problems. Conclusion Children with COVID-19 infection had a higher risk of developing psychological problems, such as withdrawal, anxiety/depression, somatic, internalizing, externalizing, and total problems.

Background Coronavirus disease 2019 (COVID-19) had a tremendous effect on individual’s lives worldwide. The pandemic’s significant socioecological impact is one of the many burdens children confront in the current crises. As a result, this study was designed to determine the psychological impacts of the COVID-19 pandemic on preschoolers, particularly the consequences of COVID-19 infection. This study involved 138 children aged 2–5.11 years old who were classified into two groups based on their COVID-19 infection history, which was documented via a PCR test. All participants were assessed by the Socioeconomic Scale and The Children’s Behavior Checklist (CBCL). Results COVID-19 infection was found in 21.7% of the children who participated in this study. Furthermore, children with COVID-19 had a higher percentage of clinical rating on the CBCL Profile of DSM-5 scales for affective problems (13.3 vs. 7.4%), anxiety problems (13.3 vs. 9.3%), pervasive developmental problems (20 vs. 13%), and oppositional defiant problems (6.7 vs. 5.6%) than children without COVID-19. Anxiety and somatic problems had a positive correlation with the impact of the COVID-19 pandemic on the lives of children. Conclusions Children infected with COVID-19 were more likely to have psychological issues, such as affective disorders, anxiety problems, pervasive developmental problems, and oppositional defiant problems. These psychological issues had a relationship with the impact of the COVID-19 pandemic on the lives of children.
