The Orygen Youth Health (OYH) model has grown from the need for evidence-based mental health services focusing on the unique needs of youth. The model has been developed from a set of key guiding principles which include client-centred early intervention, youth and family participation, clinical staging and evidence-based practice. We work from an integrated model incorporating clinical, research and training & communications expertise within our organisational structure. We work with young people and their families to ensure optimal mental health outcomes. The OYH model has been emulated in many countries around the world, including the US, UK, Canada, Switzerland, Norway, Denmark, The Netherlands, Hong Kong and Singapore.
