Objective: To identify the treated incidence of psychosis in catchment of the Early Psychosis Prevention and Intervention Centre (EPPIC), Melbourne, Australia. Method: Cases were aged 15–29 years with a first episode of a psychotic disorder accepted into EPPIC between 1997 and 2000. Age‐ and sex‐specific incidence rates per 10 000 person‐years were calculated in 5 year age bands. Rate ratios were used for age group comparisons. Results: The age‐specific treated incidence of first‐episode psychosis in 15–29‐year old individuals was 16.7 per 10 000 person‐years in males, and 8.1 per 10 000 person‐years in females. The incidence was highest in 20–24‐year‐old males and in 15–19‐year‐old females. For both sexes, incidence rates were significantly lower in the 25–29‐year age group. Conclusions: The incidence of psychosis in the catchment of EPPIC was higher than previously reported, especially in female teenagers. Peak rates in 15–24 year olds suggest a youth model approach to early psychosis may be indicated.
