The application addresses the societal challenge posed by the increasing mental illness among young people and how it contributes to unequal chances of passing school. Incomplete grades from grade 9 increase the risk of exclusion and future psychosocial problems. Despite several efforts by society, ill-health is on the rise. Society finds it difficult to tackle the problem as the current way of working and organization is not optimized for complex challenges. There has been an increasing focus on prevention, but efforts are still reactive, short-term and fragmented, even though the challenge is based on the same root causes: lack of good and equal conditions for growth. To better address root causes, foster social innovation and create more sustainable approaches to mental health, the project sees the problem on three levels: First, the "outcome level" that occurs at the individual level: increasing mental ill-health and school failure, as well as the systemic level (Blekinge and national): that the system around children and young people for various reasons is not designed to proactively promote health and equal chances of coping with school, and finally the local level; a specific context (Rödeby) where the local conditions are taken into account in the implementation of social innovations that have arisen at the three levels. The project's objectives and approach are based on all three levels. The problem is due to complex causal relationships between various factors such as lack of parental relationships and access to safe adults, negative school ties, low school attainment, social isolation, lack of meaningful leisure time and poor financial conditions. Since April 2023, a county-wide collaboration project has been underway that has created the conditions for the application to come about. Reasons that emerged when system actors met were, among other things, the target group's lack of influence, lack of common goals and objectives, hampered collaboration both within and between sectors and an individualized, performance-oriented system. There is also a low level of competence in the system to promote innovation from a system perspective. The consequences of the problem for the individual are exclusion, more physical and mental illness and difficulties in participating actively in society. For society, the costs are high in both economic and human terms. Among other things, SKR estimates that every study break costs society around SEK 11 million over a person's lifetime. The project's target group is children and young people in Rödeby and the surrounding area who live in or at risk of social and economic vulnerability. The vulnerability is due to a lack of protective and healthy factors that can lead to school absenteeism and drop-out. The needs of the target group have been mapped based on surveys, student dialogues, focus groups and parental dialogues. The project's actors consist of organizations from the public, idea-based and private sectors, all of which are actively involved in the already ongoing project and all have been involved in the development of the project idea and the respective actors' contributions. Karlskrona municipality is the "problem owner" and thus also the project owner, but Region Blekinge and all municipalities in the county are in a larger sense system owners and thus clients via the cooperation body LSVO (Leadership cooperation health and social care). Save the Children, RF Sisu and Schvung have important skills and networks that enable new and more effective ways of working with the challenge. The overall goal is to implement at three levels (individual, local and system level) a number of initiatives that have been developed based on knowledge of how innovation is promoted in complex contexts, in order to create a movement that affects the system in a more health-promoting direction. The idea is that this will really strengthen the conditions for lasting change. System-level objectives: 1.1 Actors from the public, non-profit and private sectors have gathered together around a common challenge and have a better ability to work to promote students' mental health and reduce study breaks together and counter systemic errors. 1.2 The project has contributed to actors having greater knowledge of the target group, needs and methods and working methods to better interact and meet the needs of the target group from a holistic perspective. 1.3 The project has contributed to increased knowledge among collaborative actors in order to involve children and young people in processes that concern them. 1.4 The work at this level has been brought together with the individual and local level in order to gain feedback, insight and be able to further develop. Targets at local and individual level: 2.1 Based on local needs, the project has identified together with young people, developed and tested interventions aimed at strengthening the target group's protective factors and increasing heal
