For example, in Australia the Early Psychosis Prevention and Intervention Centres (EPPIC) scheme was extended to young people to improve their access to mental health care. The motivation for doing this came from survey findings that 25% of people reporting mental disorders in Australia have their first mental ill-health episode before the age of 12, and 64% before the age of 21, and that a large treatment gap existed for this group. To take an example from Finland, when survey information highlighted groups with a particularly high suicide rate, suicide prevention was appropriately tailored towards these groups and successfully contributed to a reduced suicide rate. Investments in population-targeted surveys are most fruitful if such surveys are used to promote access to appropriate treatment, which necessitates investment and reflection around good referral and treatment pathways.
