The links between migrant status and psychosis have attracted considerable attention in recent decades. The aim of the study was to explore the demographic and clinical correlates of migrant v. Australia-born status in individuals with psychotic disorders using a large community-based sample.


Data were drawn from a population-based prevalence survey of adults with psychotic disorders. Known as the Survey of High Impact Psychosis (SHIP), it was conducted in seven Australian catchment areas in 2010. Logistic regression was used for the main analyses, examining associations of migrant status with sociodemographic and clinical variables.


Of the 1825 participants with psychotic disorders, 17.8% (n = 325) were migrants, of whom 55.7% (n = 181) were male. Compared to Australia-born individuals with psychosis, migrants were more likely to be currently married, to have completed a higher level at school, to have left school later, and to be employed with full-time jobs. Migrants with psychosis were either no different from or less impaired or disadvantaged compared to their Australian-born counterparts on a range of clinical and demographic variables.


In a sample of individuals with psychotic disorders, there was no evidence to suggest that migrant status was associated with worse clinical or socio-economic outcomes compared to their native-born counterparts.
