Youth violence is a global public health problem. It includes a range of acts from bullying and physical fighting, to more severe sexual and physical assault and even homicide. According to OECD PISA report “How prevalent is bullying at school”, 30,6% of 15-year-olds reported having faced physical or psychological abuse at school several times a month. Results of the research “Addressing Sexual Bullying Across Europe” (2015) showed that 73% of youth aged 13 to 18 have been sexually assaulted more than once in their life. According to data provided by UNESCO (2019) “Behind the numbers: Ending school violence and bullying” - Globally, one in three children experiences bullying and a similar proportion are affected by physical violence. Worldwide an estimated 200 000 homicides occur among youth 10–29 years of age each year, making it the fourth leading cause of death for people in this age group. Youth homicide rates vary dramatically between and within countries. Globally, 83% of youth homicide victims are males, and in all countries males also constitute the majority of perpetrators (source: World Health Organization). Sexual violence also affects a significant proportion of youth. For example, 3–24% of women surveyed in the “WHO Multi-country study on women's health and domestic violence” reported that their first sexual experience was forced. The rate of bullying among children and youth is a key indicator of well-being and an important marker for comparing global social development. Both victims and perpetrators (and to an extent, witnesses; UNESCO, 2016) of bullying in childhood suffer across various dimensions, including personal social development, education, and health, with negative effects persisting into adulthood. Effective prevention of violence among adolescents and young adults is a key strategy for reducing rates of bullying, gender-based violence (GBV) and school dropout, and empowering social inclusion. In 2010, MARTA Centre started a prevention program - YOUTH GROUP METHODOLOGY - for youth (ages 13-18) aiming to raise their awareness of gender equality, challenge the traditional gender stereotypes and thus reduce the risk for young boys and girls to experience violence and become victims of human trafficking and/or to become perpetrators. Evaluation of methodology shows that by participating in youth groups young people have raised their self-confidence, increased the ability to critically analyze and reflect on the world, act in an informed way towards bullying and violence, make responsible and informed decisions about their emotional, mental and physical health and interactions, create and maintain healthy, respectful relationships with their peers, teachers, parents and themselves and show more interest and engagement into social processes on local, national and international level. We see the relevance of wide spreading this methodology to meet the needs of project partner countries. OBJECTIVES: - Reduce violence-supportive attitudes by working directly with young girls and boys (ages 13-18) and by changing underlying harmful social norms and gender stereotypes that drive gender inequality and violence towards and among children and youth; - Through conducting training of Youth Group Methodology, provide needed knowledge to educational and support staff in schools and youth centers to recognize and stop violence among and towards youth (ages 13-18); - Through further local activities and international cooperation within and after this project, take part in achieving Sustainable Development Goal (SDG) 5 - achieve gender equality and empower all women and girls; SDG 4, which aims to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all, and SDG 16, which aims to promote peaceful and inclusive societies. This project aimed to unite the youth workers, educators and other professionals working with young people from the participating countries, equip them with already existing and tested knowledge of Youth Group Methodology approach, guide them through adaptation of it to local needs and cultural context, test and evaluate its effectiveness and work on next steps and future collaboration. The implementation of this project helped to realize policy strategies of European Commission by strengthening and reinforcing EU and partner countries relations in cooperation to fight discrimination, inequality and to build capacities in the field of working with youth by equipping youth workers/educators with needed knowledge, skills and attitudes to prevent violence among and towards children and youth.
