The project aimed to contribute to the promotion of Mental Health (MH) and well-being of young people and break down the stigma around it. The European Youth Forum in 2017-2018 made mental health and well-being the fifth youth goal that should be addressed by the new EU Youth strategy. Adolescence and young adulthood (age 16-25y) are crucial periods for laying the foundations for healthy development and well-being. There is compelling evidence that the promotion of mental well-being and prevention interventions, when implemented effectively, can reduce risk factors for mental disorders, enhance protective factors for good mental and physical health and lead to lasting positive effects on a range of educational, social and economic outcomes for young people. The interest for MH in youth work is increasing due to an increasingly competitive and demanding society and wrong (digital) representations of a perfect life. These situations can cause lower self-esteem and a sense of failure and this can result in stress in young people’s lives. Mental health (MH) has been defined by the WHO as a state of well-being in which an individual can realize his or her own potential, cope with the normal stresses of life, work productively and make a contribution to the community. This also means that MH is more that just the absence of psychopathology. In modern society, plenty of (young) people do not have a diagnosed mental disorder but are still not flourishing/thriving in their lives. This flourishing means that people are able most of the time to live up to their full psychological potential, being able to deal with the normal stresses of life (resilience), have emotional intelligence, experience meaning, and purpose in life, and are able to function positively in the social aspect of life. Where psychopathology falls under the domain of the health care sector, the youth sector can make major contributions to improve young people´s (including those with fewer opportunities/ special needs) positive mental health and wellbeing, often addressed through personal developmental approaches. So the main aim was to improve the wellbeing of young people, in a direct (youth exchange) and indirect way (training course). The objectives achieved by this project were: - Enhanced young people's well-being competencies (awareness, skills and attitudes) with an emphasis on intercultural peer-learning. - Improved participant’s foreign language skills and enhanced participants' knowledge of cultural diversity and European citizenship. - Fostered active participation in their local communities and society at large; in particular, in relation to promoting sustainably sound attitudes and behaviors to the wellbeing of individuals, groups and society - Increased the competencies of the youth workers from the partner organisations in order to increase the quality of their youth work on mental health promotion. - Established and provided partner organisations with a network opportunity to increase the internationalization of their youth work on wellbeing promotion.
