Objective:
Our objective is to explore the change in the severity of ADHD, ODD and anxiety during a two-month lockdown among children in France and the moderating role of behavioural regulation.
Method:
In 235 children with ADHD, the symptom severity of ADHD, ODD and anxiety was investigated one and two months after the beginning of lockdown, and one month after its end. Behavioural regulation skills were estimated with the Behaviour Regulation Index.
Results:
ADHD, ODD and anxiety scores were increasing or decreasing depending on BRI.
Conclusion:
Baseline behavioural regulation skills may act as a moderating factor for the persistence of ADHD, ODD and anxiety symptoms related to the lockdown.
