Emerging mental health problems during the COVID-19 pandemic among presumably resilient youth -a 9-month follow-up.

Our results imply that in the wake of the pandemic, one should be aware of emerging mental health problems among presumably resilient youth, in addition to the more expected and pronounced mental health needs of vulnerable groups. Efforts to reach out to the general youth population with preventive measures in schools may be important actions to normalize the situation for young people, and to identify those in need of more targeted mental health interventions.
