The clinical and functional outcomes of a large naturalistic cohort of young people accessing national early psychosis services.

Aims: Services for individuals with a first episode of psychosis or at ultra-high risk of psychosis have become a treatment model of choice in mental health care. The longitudinal changes in clinical and functional outcomes as a result of real-world treatment remain under-reported.

Methods: We analysed data from first episode of psychosis and ultra-high risk services delivered across Australian primary youth mental health care services known as between 19 June 2017 and 30 September 2019.
