Adolescence is a transitional period during which a child undergoes social and emotional changes, adding a layer of vulnerability to increased anxiety symptoms. The COVID-19 pandemic disrupted many lives, confining adolescents to their homes and inducing external stressors for parents. For this study, we found that less parental support of adolescents’ reappraisal was associated with higher levels of adolescent anxiety. This effect was more significant among families who were highly impacted by the pandemic.
