CoCo-20: a Longitudinal Follow-up Study of the French Paediatric Population During and After the Coronavirus Pandemic COVID-19

In the context of a viral outbreak and of widespread quarantine measures, a significant increase in psychological disorders, such as stress or fear behaviours, had previously been observed. This distress has been described on adults, but no data have been collected yet for paediatric populations.

After a traumatic event, children and adolescents may present several clinical consequences, the most common being Post-Traumatic Stress Disorder (PTSD). Moreover, PTSD in children and adolescents is often associated with comorbid disorders, such Attention Deficit Hyperactivity Disorder, depression, attachment and anxiety disorders, sleep disturbances and behavior problems.

The aim of this study is to present the methodology of "CoCo 20" : is to assess the impact of the pandemic of coronavirus disease 2019 (Covid-19) and of seclusion measures on mental health and on the development of psychological disorders in children in the short to medium term
