The coronavirus disease (COVID-19) pandemic is causing a global health crisis of unprecedented proportions in modern times. Importantly, the pandemic is expected to have negative health consequences beyond those caused by the coronavirus per se – including significant psychological distress. This symposium will focus on the mental health consequences of the COVID-19 pandemic. First, Dr. Christoph U. Correll will provide an overview of the design of the “Collaborative Outcomes study on Health and Functioning during Infection Times” (COH-FIT), putting it in the context of available evidence when the study started. He will present also global results from over 100 countries across 6 continents, focusing on the subgroup of >15,000 minors, in whom their caregivers rated the impact of COVID-19 on their physical and mental well-being. Second, Dr. Marco Solmi will present global results of COH-FIT study in adults from over 100 countries and >50,000 participants across 6 continents, with a specific focus on Italian sample (over 7,000 respondents, including a nationally representative sample). Third, Dr. Karolina Skonieczna-Żydecka will present results of the COH-FIT study in Poland with >1500 participants, with a specific focus on health workers. Fourth, Dr. Søren D. Østergaard will present the results of a survey in which 6000 randomly drawn patients with mental disorders undergoing treatment in the psychiatric services of the Central Denmark Region (catchment area of 1.3 million people) will be involved. The survey, which will be conducted in June 2020, will focus on well-being and symptom levels of the participants during the COVID-19 pandemic.
