This is not unique to the United Kingdom, as mental health problems are gradually becoming the main cause for disability claims across OECD countries, accounting on average for a third of the total and often more than half for young people (OECD, 2012b). According to an evaluation for the OECD Mental Health and Work project (OECD, 2013), the United Kingdom is among the most advanced countries in terms of awareness about the costs of mental illness for employers and society as a whole, and of the mental-health benefits of employment. Integration of health and employment services is also well developed, as illustrated by the Improving Access to Psychological Therapies (IAPT) initiative which aims to provide access to both evidence-based psychological therapies and matching employment services.
