摘要：The COVID-19 pandemic increased the incidence of distress in youth, including PTSD symptoms. The purpose of this longitudinal study was to assess the anxiety-related socioemotional predictors of PTSD symptoms in reaction to COVID-19 in youth. To do so, 84 children aged between 9 and 14 who previously participated in a laboratory-based experiment between 2017 and 2019 (T0) were recontacted to take part in this COVID follow-up. They filled online questionnaires in June 2020 (T1: 3 months of home confinement), September 2020 (T2: back to school), and December 2020 (T3). Participants were free of mental illness at T0 and T1. Method: To assess predictors of PTSD symptoms, we measured anxiety sensitivity (Childhood Anxiety Sensitivity Index) at T0, and trait anxiety (State-Trait Anxiety Inventory for Children), intolerance to uncertainty (Intolerance of Uncertainty Scale for Children), and trait rumination (Children’s response style scale) at T1. PTSD symptoms were measured using the Children’s Revised Impact of Event Scale at T1, T2, and T3. Results: Controlling for sex and age, a linear mixed model revealed a main effect of anxiety sensitivity [F (1,66) = 4.187; p = .046], with children high on anxiety sensitivity presenting increased PTSD symptoms. We also found a quadratic time*rumination effect [F(1,66) = 3.023; p = .008], with high ruminators presenting increased PTSD symptoms at T2 [B = .329, p = .004]. Conclusions: Our results suggest that anxiety sensitivity higher symptoms when going back to school after six months of home confinement.
