Youth, as being defined between 12-25 years, is the period of life when most mental ill-health has its onset. Some principles are defined to guide local implementation of youth mental health care in any resource setting or country: 1-awareness, engagement and integration, 2-easy and affordable access 3-youth-specific care, 4-youth partnership, 5-prevention, 6-early intervention, 7-family engagement and support, and 8-continuous improvement. However, care needs are far from being met. The presenters will talk about their experience and studies that attempted to address these principles in different contexts, populations and in different countries of Europe. Ekin Sonmez will discuss how social norms approach could be applied to prevent alcohol and substance use disorders in youth. Diego Quattrone will present an international study aiming to answer questions on cannabis and risk of first-episode psychosis. Aleksandar Savic will propose a model and report on the attempt of utilizing existing clinical programs (first episode psychosis and non-psychosis youth services) in providing adequate care for at-risk youth. Gaia Sampogna will discuss the consequences of being exposed to traumatic events (such as cyberbullying or the recent pandemic) on the mental health of young people. Victor Pereira-Sanchez will present his studies applying social media content analysis on Twitter to explore public perceptions regarding pathological social withdrawal (hikikomori). Ozge Kilic will talk about her experience in youth-specific care and discuss their study on functionality and mental health outcomes in the college population. (This workshop is being proposed for the ECPC track by ECPC Task Force on Research).
