New interventions for mild-to-moderate disorders can represent good value for money. Stepped care for mild-to-moderate mental illness has been supported as a cost-effective approach with good outcomes by a wide range of clinical guidelines, and low-intensity interventions such as bibliographic and guided self-help, peer support groups, and a range of new internet-based interventions can be effectively implemented with low costs, especially when backed with support from primary carers. For cases which need higher intensity interventions, an expanded and more diverse workforce is needed, along with a wider range of available treatments. Specialist vertical programmes targeted at significantly expanding available treatment for mild-to-moderate disorders have been put in place in a small number of cases with considerable success.
