COVID-19 and the impacts on youth mental health: emerging evidence from longitudinal studies

Several experts have warned that the current coronavirus disease 2019 (COVID-19) pandemic and associated confinement measures may have taken a devastating toll on youth mental health. While the COVID-19 pandemic has certainly created important challenges for children and youth, these claims vastly rely on cross-sectional data collected during the pandemic, from which it is difficult to draw firm conclusions. In this commentary, we offer a critical appraisal of the evidence from emerging longitudinal studies spanning the pre- and intra-pandemic period with a focus on internalizing and externalizing disorders, suicidality, eating disorders and substance use. We also discuss important research considerations in the monitoring of the long-term impacts of the COVID-19 pandemic on youth mental health as well as promising interventions to help mitigate potential long-lasting consequences of this unprecedented public health crisis.
