Understanding de novo onset of anxiety during COVID-19: Pre-pandemic socio-emotional functioning in vulnerable children.

Background: There is a need to understand and mitigate the psychological impacts of the COVID-19 pandemic for children known to be vulnerable. Data from prior to the pandemic are required to provide robust assessments of the socio-emotional impacts of COVID-19 and identify those who are more vulnerable. Method: This study capitalises on an ongoing UK study of primary school children (4-8 years) identified prior to the pandemic as "at risk" for mental health problems by teachers. We collected mental health and social-emotional functioning data prior to the pandemic (Time 1) and re-assessed this cohort ( Results: Mental health problems, particularly clinically significant anxiety, increased from 34% to 43% during lockdown and to 48% post-lockdown. Parental mental health difficulties (anxiety and depression) were prevalent during lockdown (40%) but had decreased 1 year later (20%). Children who developed clinically significant anxiety during the pandemic had impaired socio-emotional functioning at Time 1 (i.e., impaired emotion recognition, low self-esteem and social problems) and a high proportion (44%) had no contact with any peers during lockdown, which may have contributed to their anxiety, especially their school anxiety. Conclusion: The pandemic appears to have exacerbated anxiety in already vulnerable children. A profile of socio-emotional problems identified a group of children who developed significant anxieties during the pandemic. These socio-emotional processes can be targeted for intervention to mitigate the negative mental health consequences of the pandemic and contribute to resilience in children.
