The source provides a comprehensive synthesis of evidence advocating for a structural paradigm shift in mental health, moving beyond individual clinical treatment to address macro-level societal determinants of wellbeing. It emphasizes that mental health outcomes are fundamentally shaped by upstream factors, such as economic stability, housing quality, and equitable education systems, rather than purely biological or psychological ones. The document reviews evidence for structural interventions across these domains, including universal basic income and anti-discrimination policies, concluding with a multi-sectoral roadmap for governments to create a more just and supportive society, thereby promoting population-level mental health. The ultimate goal is to shift responsibility for mental health from the individual to politics and governance.
