What does a mental health-in-all-policies approach look like?

This chapter provides the rationale of a whole‑of-government approach, set out in the OECD Recommendation on Integrated Mental Health, Skills and Work Policy, and explains the importance of an integrated, cross-sectoral approach to mental health policy. It introduces the “who, when and what” (or the three Ws) of effective integrated mental health policy as outlined in the implementation report on the Recommendation, which argues that countries need to take into account “who” is carrying out an intervention, “when” intervention is taking place, and “what” such interventions look like.
