Organised by EUPHA Section on Public Mental Health, WFPHA, University of Applied Sciences Emden / Leer , Emden, Germany; University of Geneva, Geneva, Switzerland Brief outline of the overall workshop Mental disorder is responsible for at least a fifth of global disease burden due to high prevalence, early onset in the life course and a broad range of public relevant impacts. Mental wellbeing is also an important asset and results in wide ranging impacts. Effective interventions exist to treat mental disorder, prevent associated impacts, prevent mental disorder from arising, and promote mental wellbeing and resilience. Such interventions are delivered by different sectors including public health. Prior to the COVID-19 pandemic, only a minority of those with mental disorder received interventions with negligible coverage of effective interventions to prevent associated impacts, prevent mental disorder or promote mental wellbeing and resilience. This implementation gap has further widened since the COVID-19 pandemic and results in population scale preventable human suffering, public health relevant impacts and associated economic costs. Public Mental Health is therefore an important part of public health and supports the achievement of a range of public health objectives. However, to date, this issue has received little attention in the public health arena. Specific aims / Objectives The workshop session will * Share recent research and insights on mental disorders and wellbeing before and during the pandemic� * Consider reasons for implementation failure of effective PMH interventions and required actions to address this through PMH practice * Create a space sharing knowledge and expertise hearing the insights of the participants as part of interdisciplinary ethical, professional and policy efforts needed to promote Public Mental Health. The key questions that the workshop will address * What is the extent of mental disorder, poor mental wellbeing and associated risk/protective factors at population level and how to assess in order to inform population need? * What are options for mental disorder prevention, amelioration and care, and promotion of mental wellbeing and resilience? * What is the role of public health to support scale implementation of evidencebased PMH interventions?
