Insights
The COVID-19 lockdown negatively impacted preschool children's emotional-behavioral functioning, with decreased prosocial behavior observed. Attending leisure activities before lockdown predicted worse outcomes, highlighting the need for mental wellbeing awareness during crises.
Area of Science:
- Child Psychology
- Public Health
- Behavioral Science
Background:
- The COVID-19 pandemic necessitated lockdowns and home confinement, raising concerns about unintended negative consequences on child behavior.
- Understanding changes in emotional-behavioral functioning during such crises is crucial for effective interventions in current and future health emergencies.
Purpose of the Study:
- To determine if the Danish COVID-19 lockdown affected emotional-behavioral functioning in preschool children.
- To examine if baseline family and social characteristics predicted changes in child behavior during lockdown.
Main Methods:
- A sub-study of the ODIN-study involving 40 preschool-aged children.
- Parents completed the Strength and Difficulties Questionnaire (SDQ) before and three weeks into lockdown.
- Analysis of SDQ-Total Difficulties (SDQ-TD) and Prosocial Behavioral (PSB) scores, and prediction of changes using baseline characteristics.
Main Results:
- A significant increase in SDQ-Total Difficulties scores (from 6.0 to 7.9) and a significant decrease in Prosocial Behavioral scores (from 8.5 to 7.9) were observed.
- Attending pre-lockdown leisure activities predicted a worsening of children's SDQ-TD scores (mean difference 3.16).
- A modest decrease in overall child emotional-behavioral functioning during lockdown was indicated.
Conclusions:
- The COVID-19 lockdown was associated with a decline in preschool children's emotional-behavioral functioning.
- Parental stress may have contributed to these negative outcomes.
- Increased awareness of child mental wellbeing during lockdown situations is necessary, despite limitations in generalizability due to sample size.
Abstract:
Unintended negative outcomes on child behavior due to lockdown and home confinement following the corona virus disease (COVID-19) pandemic needs highlighting to effectively address these issues in the current and future health crises. In this sub-study of the ODIN-study, the objectives were to determine whether the Danish lockdown and home confinement following the COVID-19 pandemic affected changes in emotional-behavioral functioning of pre-school-aged children using the validated Strength and Difficulties Questionnaire (SDQ) answered by parents shortly before lockdown and 3 weeks into lockdown, and moreover, to examine whether baseline family and social characteristics could predict change in child emotional-behavioral functioning during lockdown. Parents of 40 (82%) children with a mean(SD) age of 5.0(0.7) completed the baseline questionnaire and the lockdown follow-up questionnaire. The SDQ-Total difficulties score (SDQ-TD) and Prosocial Behavioral score (PSB) changed significantly from pre- to lockdown [SDQ-TD mean(SD): 6.0(3.8) and 7.9(5.2); P = 0.02, respectively and PSB mean(SD): 8.5(1.4) and 7.9(1.5); P = 0.03, respectively]. Attending leisure time activities before lockdown was a predicting factor of changes to the worse in the children's SDQ-TD scores, with a mean difference in SDQ-TD between those with and without activities of 3.16 (95%CI 0.27-6.12); P = 0.03. In conclusion, the study showed a modest decrease in child-emotional behavioral functioning during the COVID-19 lockdown, potentially due to parental stress. Although these results might not be generalizable due to small sample size and selected population, the results point to a need of a greater awareness of child mental wellbeing during a lockdown situation.
