Longitudinal Effects of the Pandemic and Confinement on the Anxiety Levels of a Sample of Spanish Children in Primary Education

(1) Background: The psychological effects of confinement due to the SARS-CoV-2 virus pandemic on children are only partially known. In Madrid, Spain, children suffered a strict confinement for 10 weeks and they returned to school under conditions that were far from normal. This work assesses the effects of the pandemic on the anxiety levels of a group of children living in Madrid. (2) Methods: Children were aged 6 to 11 years (N = 215). A self-report measure of anxiety was completed by participants at two time-points: (1) a few months before the beginning of the pandemic and (2) 1 year later. A smaller subgroup of participants also completed the measure during the confinement period (n = 60). (3) Results: A comparison of these three measures shows that the children’s anxiety was reduced during confinement, and that one year later these levels continue below those registered before the start of the pandemic. (4) Conclusions: These results contradict some previous studies, which found an increase in children’s anxiety as a result of confinement and the pandemic. The discussion considers protective and vulnerability factors in the context of the pandemic, which may affect children’s levels of anxiety.
